Spare Parts for Holzmann HOB305ABS: Maintain and Repair Your Planer Thicknesser

Discover our selection of spare parts for the Holzmann HOB305ABS planer thicknesser, specially grouped together to make maintenance, troubleshooting and repairs on your woodworking machine easier.

The Holzmann HOB305ABS is a planer thicknesser equipped with an integrated dust extraction system. It performs two essential woodworking operations: surface planing, which produces a flat face and a reference edge, and thicknessing, which brings wooden workpieces to the required thickness.

Over time, certain components may wear out, deteriorate or require replacement. A damaged belt, worn drive chain, defective pulley or electrical fault can interfere with the machine's operation.

At Probois Machinoutils, we offer replacement parts for the main mechanical and electrical assemblies of your Holzmann HOB305ABS.

Our selection includes transmission belts, a drive chain, a motor pulley, dust extraction components, planer knives, and electrical control and protection components.

Each part must be selected according to its reference number, technical specifications and the list of compatible machines provided on its product page.

940J5 (370J) Motor Drive Belt, Position 116, for Holzmann HOB305ABS

The motor drive belt transmits movement between the motor and the planer thicknesser's drive system.

Our selection includes the 940J5 (370J) Poly-V motor drive belt, position 116, intended in particular for the 230 V version of the Holzmann HOB305ABS.

Its specifications are:

• Marking: 940J5 / 370J.

• Type: Poly-V belt.

• Number of ribs: 5.

• Position on the exploded parts diagram: 116.

A motor drive belt may need replacing if it shows cracks, damaged ribs, deformation or breakage.

Slipping can also cause irregular power transmission.

However, a loss of power is not necessarily caused by the belt. The pulleys, the condition of the driven mechanism and the operating conditions should also be checked.

Before fitting a new belt, inspect the pulleys for damage that could cause premature wear.

Important: the 940J5 motor drive belt must not be confused with the 520J3 impeller belt or the 695 × 10 mm flat belt. These three references perform different functions.

520J3 (205J) Impeller Drive Belt, Position 126, for the Dust Extraction System

The Holzmann HOB305ABS features an integrated dust extraction system designed to collect wood chips produced during machining.

Our category includes the 520J3 (205J) impeller drive belt, position 126.

This Poly-V belt transmits the movement required to drive the dust extraction impeller on compatible machines.

Its specifications are:

• Reference: 520J3 (205J).

• Number of ribs: 3.

• Type: Poly-V belt.

• Position: 126.

An impeller belt may need replacing if it is broken, worn, stretched or damaged.

If the dust extraction system is no longer working correctly, start by checking the condition of this belt, as well as the impeller and the chip extraction circuit.

Insufficient extraction can also be caused by a clogged filter bag, a blocked extraction outlet or an accumulation of wood chips.

Check the 520J3 (205J) marking and position 126 before ordering this belt.

695 × 10 mm Flat Belt, Position 151, for Holzmann HOB305ABS

Our selection also includes a 695 × 10 mm flat transmission belt, position 151, intended in particular for the 230 V version of the Holzmann HOB305ABS.

This belt is different from the two Poly-V belts described above.

Its specifications are:

• Type: Flat belt.

• Specified length: 695 mm.

• Width: 10 mm.

• Position: 151.

A flat belt may need replacing if it is cut, cracked, deformed or no longer provides proper power transmission.

Before ordering, identify the exact belt that needs replacing on your machine's exploded parts diagram.

Also check the dimensions of the original component.

A belt with apparently similar dimensions is not necessarily a suitable replacement.

53-Link Drive Chain, Position 82, for Holzmann HOB305ABS

The drive chain forms part of the planer thicknesser's feed mechanism.

Our category includes a 53-link drive chain, position 82, specifically listed for the Holzmann HOB305ABS and HOB305ABSSMW2 models.

Its specifications are:

• Number of links: 53.

• Position: 82.

• Holzmann reference: 10017602.

This chain transmits movement between the relevant mechanical components.

A chain may need replacing if it shows significant wear, damaged links, deformation or breakage.

Unusual mechanical noises and irregular operation of the mechanism may also indicate that an inspection is necessary.

Before replacing the chain, it is important to check the condition of the sprockets and investigate any possible cause of mechanical blockage.

A damaged sprocket can cause premature wear of a new chain.

Important: this chain has 53 links. It must not be confused with another drive chain that has a different number of links.

The manufacturer's reference 10017602 and position 82 make identification easier.

Motor Pulley, Position 113: Holzmann References 10002928 and 10017609

The motor pulley transmits movement between the motor and the components driven by the belt.

Our selection includes the motor pulley, position 113, associated with Holzmann references 10002928 and 10017609.

It is intended in particular for the Holzmann HOB305ABS and HOB305ABSSMW2 planer thicknessers, according to the compatibility information.

A motor pulley may need replacing if it shows:

• Cracks or breakage.

• Deformation.

• Damage to the grooves.

• Abnormal wear.

• A defective fastening system on its shaft.

A damaged pulley can cause vibrations, poor drive transmission or accelerated belt wear.

Before replacing the pulley, also check the condition of the motor drive belt and the fastening system.

Always identify position 113 and references 10002928 / 10017609 before ordering.

A visually similar pulley may have a different diameter, bore or profile.

How to Diagnose a Transmission Problem on the Holzmann HOB305ABS

If your planer thicknesser experiences a loss of drive, unusual noises or irregular operation, several components may be involved.

Always unplug the machine before carrying out an inspection.

Check the following in particular:

• The 940J5 motor drive belt.

• The 695 × 10 mm flat belt.

• The 53-link drive chain.

• The motor pulley.

• The other pulleys and sprockets in the mechanism.

A broken belt can interrupt power transmission.

A damaged chain can prevent the mechanism it drives from operating correctly.

A damaged pulley can cause incorrect belt positioning.

It is important to investigate the exact cause of the problem before ordering a part.

Replacing a belt will not necessarily solve the fault if a pulley or an associated mechanism is defective.

Cotton Filter Bag for Holzmann HOB305ABS and HOB305ABSSMW2

The integrated dust extraction system collects wood chips produced during surface planing and thicknessing.

Our category includes a cotton filter bag for Holzmann HOB305ABS and HOB305ABSSMW2, also listed for the Bernardo PT305D(S) models.

The filter bag helps separate and collect extracted dust and wood chips, depending on the system configuration.

Over time, it may become clogged or deteriorate.

Replacement may be necessary if it shows:

• Tears.

• Damaged seams.

• A damaged fastening system.

• Significant fabric wear.

• Deterioration that prevents proper use.

However, reduced extraction performance does not automatically mean that the bag needs replacing.

Start by checking its condition, the level of clogging and whether the extraction circuit is obstructed.

Follow the manufacturer's instructions for cleaning and maintaining the system.

Belts, Impellers and Extraction Outlets: Components of the Integrated Dust Extraction System

The dust extraction system depends on several components working together.

The impeller drive belt transmits movement.

The impeller or fan generates the airflow required for extraction.

The extraction outlet directs wood chips towards the collection system.

The filter bag helps collect the extracted material.

Our category also includes dust extraction components offered for various Holzmann and Bernardo planer thicknessers.

However, the presence of an extraction outlet or fan in this category does not automatically confirm compatibility with the Holzmann HOB305ABS.

Certain product pages specifically mention the HOB260ABS, PT260 or PT305D models.

Before ordering an extraction outlet or fan for your HOB305ABS, check that this exact model is explicitly included in the list of compatible machines.

Do not rely solely on the appearance of the component.

Holzmann HOB305ABS Dust Extraction Is No Longer Working: What Should You Check?

If your machine is no longer extracting wood chips correctly, several causes should be considered.

Check the following in particular:

• The condition of the 520J3 impeller drive belt.

• Whether the extraction outlet is blocked.

• The condition of the fan or impeller.

• The condition of the filter bag.

• Whether excessive wood chips have accumulated.

A broken belt can prevent the impeller from being driven.

A blocked extraction outlet can significantly reduce airflow.

A heavily clogged filter bag can also reduce system performance.

Before carrying out any work, unplug the machine and follow the manufacturer's instructions.

Never put your hands or a tool into a moving mechanism.

Once the cause has been identified, you can select the appropriate spare part.

308 × 20 × 2.5 mm Planer Knives for Holzmann HOB305ABS

Planer knives are the cutting elements of the cutterblock.

They directly affect the quality of surface planing and thicknessing.

Our selection includes a planer knife made from steel containing 18% chromium, measuring 308 × 20 × 2.5 mm, sold individually.

Its specifications are:

• Length: 308 mm.

• Width: 20 mm.

• Thickness: 2.5 mm.

• Steel specified as containing 18% chromium.

• Packaging: Sold individually.

Blunt knives can reduce cutting quality, cause tear-out or increase the effort required during machining.

Chipped knives can also leave marks on wooden workpieces.

Before replacing the knives, check their exact dimensions and compatibility with your machine's cutterblock.

Follow the manufacturer's instructions for installation, adjustment and tightening.

Important: these planer knives are sold individually. Check the quantity required before ordering.

Never operate the machine if the knives are damaged or their fastening system shows any signs of a fault.

Emergency Stop Switch for the 230 V Holzmann HOB305ABS Planer Thicknesser

The emergency stop switch is an essential component of the electrical control and safety system.

Our category includes a replacement emergency stop switch intended for several Holzmann and Bernardo planer thicknessers in 230 V versions.

It allows the machine to be stopped quickly when a situation requires immediate intervention.

An emergency stop switch may need replacing if it is broken, damaged or no longer operates correctly.

A malfunction may involve the button, its mechanism or the associated electrical contacts.

Before ordering, check compatibility with your machine and the specifications of the original component.

Never operate your planer thicknesser if its emergency stop switch is defective.

Any work on the electrical circuit must be carried out with the machine unplugged and by a person with the necessary skills.

15 A Overload Protector, Position 194, for Holzmann HOB305ABS

Our selection includes a 15 A overload protector, position 194, intended for several Holzmann and Bernardo planer thicknessers in 230 V versions.

This electrical protection device responds to overloads or excessive current to help protect the motor and electrical circuit.

Its main specifications are:

• Rated current: 15 A.

• Position: 194.

• Intended for: Compatible 230 V machines.

An overload protector may need replacing if it is defective or no longer performs its function correctly.

However, repeated tripping does not necessarily mean that the protector itself is faulty.

It may indicate a mechanical overload, a motor problem or an electrical fault.

Before replacing this component, it is therefore essential to investigate the cause of the tripping.

Never bypass the overload protector or replace it with a device having different electrical specifications without technical approval.

QKS8 Switch: Identify the Correct Electrical Component

Our category also includes a QKS8 switch intended for various woodworking machines from several brands.

A switch forms part of the machine's electrical control system.

When a switch becomes defective, the machine may have difficulty starting or may stop working altogether.

However, these symptoms can also originate from other electrical components.

Before ordering a QKS8 switch, always check:

• The reference printed on the original switch.

• The electrical voltage.

• The number of terminals.

• The terminal arrangement.

• The electrical specifications.

• Compatibility with your machine.

The presence of the QKS8 switch in this category does not guarantee that it is suitable for every version of the Holzmann HOB305ABS.

Never modify the original wiring to adapt a non-compliant switch.

Holzmann HOB305ABS Will Not Start: How Can You Identify the Cause?

A planer thicknesser that will not start may be affected by different types of faults.

The problem may originate from the power supply, a safety device, the control system or a mechanical issue.

Several components should be considered:

• The electrical power supply.

• The emergency stop switch.

• The overload protector.

• The switch or contactor.

• The machine's safety devices.

• The condition of the motor and driven mechanism.

If the overload protector trips, investigate the cause before attempting another start.

If the motor makes an unusual noise or struggles to start, do not repeatedly attempt to restart it.

Repeated attempts may make the fault worse.

Unplug the machine and have the electrical checks carried out by a qualified person.

A component should only be replaced after the fault has been identified and the original reference has been checked.

Are Holzmann HOB305ABS Spare Parts Compatible with the HOB305ABSSMW2 Version?

Certain spare parts are shared by the Holzmann HOB305ABS and HOB305ABSSMW2 models.

This is particularly the case for several references in our selection, including:

• The 940J5 motor drive belt, position 116.

• The 520J3 impeller drive belt, position 126.

• The 695 × 10 mm flat belt, position 151.

• The 53-link drive chain, position 82.

• The motor pulley, position 113.

• The cotton filter bag.

However, compatibility of these references does not mean that all parts from the two machines are interchangeable.

Differences may exist between versions or manufacturing periods.

It is therefore essential to consult the list of compatible machines on each product page.

Also check the month and year of manufacture and the serial number whenever this information is required.

Compatibility with Bernardo PT305D and PT305DS

Certain parts for the Holzmann HOB305ABS are also offered for the Bernardo PT305D and PT305DS planer thicknessers.

Several belts and the motor pulley are among the components associated with these different models.

This compatibility can make it easier to identify certain shared references.

However, it must not be generalised to the entire machine.

A part compatible with a Bernardo PT305D is not automatically compatible with a Holzmann HOB305ABS.

Fastening systems, dimensions and mechanical specifications may vary between components.

Only the compatibility list provided on each spare part's product page can confirm which models are supported.

How to Identify the Correct Spare Part for Holzmann HOB305ABS

Before ordering, start by identifying your machine precisely.

Record the information on its identification plate and consult the exploded parts diagram corresponding to your model.

Useful information includes:

• Brand: Holzmann.

• Exact model: HOB305ABS.

• Supply voltage.

• Serial number.

• Month and year of manufacture.

• Part position on the exploded diagram.

• Manufacturer's reference.

• Dimensions and specifications of the original component.

For a belt, check its marking and number of ribs.

For a chain, check the number of links.

For a pulley, identify its reference and position number.

For an electrical component, check the specifications printed on the original part.

For a planer knife, check its exact dimensions.

WARNING: BEFORE PURCHASING, you must check that your machine appears in the LIST OF COMPATIBLE MACHINES provided on the spare part's product page. Where necessary, also check your machine's month and year of manufacture and serial number.

Maintain Your Holzmann HOB305ABS Planer Thicknesser Regularly

Regular maintenance helps identify signs of wear and reduce the risk of breakdowns.

With the machine unplugged, periodically inspect accessible components in accordance with the manufacturer's instructions.

Pay particular attention to the condition of the belts, pulleys and transmission mechanisms.

Also check the integrated dust extraction system and remove accumulated wood chips using the recommended methods.

Inspect the filter bag and make sure that the extraction circuit is not obstructed.

Watch for unusual noises, vibrations and feed problems.

Regularly check the condition of the planer knives and follow the correct installation and adjustment procedures.

Electrical safety devices must remain fully functional.

Any fault involving the emergency stop switch or overload protector must be addressed before the machine is returned to service.

Appropriate maintenance helps preserve your machine's performance and extend its service life.

Repair Your Holzmann HOB305ABS Instead of Replacing the Entire Machine

A localised fault does not necessarily require replacing your entire planer thicknesser.

A broken belt, worn chain, damaged pulley or deteriorated filter bag can be replaced individually when a compatible spare part is available.

However, it is important to investigate the cause of the failure.

A belt that wears out quickly may indicate a pulley defect.

A broken chain may be the result of a mechanical blockage.

An overload protector that trips repeatedly may indicate a more serious problem.

Replacing the visibly defective component must therefore not conceal another fault.

A targeted repair, carried out after an appropriate diagnosis, allows you to retain components that are still functional and extend the service life of your equipment.
