At Probois Machinoutils, we offer a selection of replacement parts to help you repair defective components without replacing the entire machine.

To find the correct replacement, it is essential to identify your exact model, its supply voltage and the reference of the original component.

Important: the Holzmann HOB305PRO must not be confused with the HOB305ABS, HOB305ABSSMW2 or HOB305PROSMW2 models. Their components are not necessarily interchangeable.

305 × 25 × 3 mm Planer Blades for Holzmann HOB305PRO

Planer blades are essential for achieving an even wood surface and a high-quality finish.

The Holzmann HOB305PRO with a conventional cutterblock is equipped with four planer blades measuring 305 × 25 × 3 mm.

Our selection includes HSS planer blades with these dimensions, sold individually.

Their specifications are:

• Length: 305 mm.

• Width: 25 mm.

• Thickness: 3 mm.

• Material: High-speed steel (HSS).

• Quantity fitted to the conventional cutterblock: 4 blades.

Sharp planer blades provide a consistent cut and help reduce excessive cutting forces during surface planing and thicknessing.

Conversely, blunt blades can cause poor surface quality, torn wood fibres, increased cutting resistance or feeding difficulties.

They may also place additional strain on the motor and transmission components.

The blades should be inspected regularly and replaced or sharpened when their condition requires it.

To maintain proper cutterblock balance and operation, follow the manufacturer's instructions concerning blade replacement, adjustment and the balancing of the complete assembly.

Before ordering, always check the 305 × 25 × 3 mm dimensions and the cutterblock configuration of your machine.

Conventional planer blades are not suitable for a helical cutterblock equipped with carbide inserts.

Blade Fastening Screws and Clamping Components

Correctly securing the planer blades to the cutterblock is essential for machine safety and precision.

Depending on the configuration of your Holzmann HOB305PRO, different fastening components may be required when working on the cutterblock.

A clamping screw or fastening component may need replacing if it shows:

• Damaged threads.

• A damaged screw head.

• Deformation.

• Cracks or breakage.

• An inability to provide the specified clamping force.

It is essential to use components that meet the manufacturer's specifications.

A screw with an unsuitable length or strength may compromise the secure fastening of the blade.

Never replace a blade fastening screw with one that merely looks similar.

Before ordering, identify the exact position on the exploded parts diagram and check the dimensions of the original component.

After working on the blades, carry out the checks and adjustments specified by the manufacturer before returning the machine to service.

Drive Belts for Holzmann HOB305PRO

Drive belts transmit movement between the motor and the mechanical components of the planer thicknesser.

Over time, they may stretch, crack, become deformed or break.

A damaged belt can cause vibrations, unusual noises, irregular power transmission or the complete failure of a mechanism.

If your Holzmann HOB305PRO shows these symptoms, inspecting the belts may be necessary.

In particular, check:

• The overall condition of the belt.

• Its original marking.

• Its profile.

• Its dimensions.

• The condition of the pulleys.

• The alignment of the transmission components.

A new belt will not provide a lasting solution if a pulley is damaged or a mechanism remains blocked.

Important: do not order a belt intended for the HOB305ABS or HOB305ABSSMW2 without confirming its compatibility with the HOB305PRO.

The machine model and the original belt specifications must match the information provided on the product page.

Drive Chains and Feed Mechanisms: Identify the Fault Before Ordering

The feed mechanism of a planer thicknesser contains several components that transmit movement to the wood-feeding system.

When the wood no longer feeds correctly, moves in jerks or stops during thicknessing, the cause of the malfunction must be identified.

Components that may require inspection include chains, sprockets, rollers and transmission parts.

A loose, worn or broken chain can interfere with the mechanism. However, a feeding problem may also originate from another component.

Before replacing a part, unplug the machine and perform the checks recommended by the manufacturer.

Chains offered for other Holzmann models are not automatically compatible with the HOB305PRO. Check their dimensions, number of links and position on the exploded parts diagram.

Our selection also includes a 6 A fuse for the Holzmann HOB305PRO.

This fuse is a separate reference from the 20 A model.

The two components must not be considered interchangeable.

The correct choice depends on the relevant circuit and the electrical configuration of your machine.

Before ordering, check:

• The current rating marked on the original fuse.

• The component's specifications.

• The voltage and version of the machine.

• The compatibility information on the product page.

A 6 A fuse must not be replaced with a 20 A fuse simply because both are offered for the Holzmann HOB305PRO.

Always use the fuse rating and specifications prescribed by the manufacturer.

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

Cutterblock Guard for Holzmann HOB305PRO Planer Thicknesser

The cutterblock guard is an essential safety component of the planer thicknesser.

Our category includes a cutterblock guard intended for the Holzmann HOB305PRO.

When correctly installed and adjusted, this component helps restrict access to the cutting area during surface planing.

A guard may need replacing if it is broken, deformed, cracked or if its fastening system can no longer hold it securely.

Wood No Longer Feeds Through Your Holzmann HOB305PRO: Which Parts Should You Check?

When wood no longer feeds correctly through the thicknesser, several possible causes should be considered.

The problem may appear as irregular feeding, jerky movement, a stationary workpiece or difficulty at the machine's exit.

Before any inspection, switch off and unplug the machine.

Then check the following components in accordance with the operating manual:

• The condition of the feed rollers.

• The transmission mechanism.

• The belts.

• Chains and sprockets, depending on the configuration.

• Any wood chips blocking the mechanism.

• The condition and adjustment of the planer blades.

Blunt blades can increase cutting resistance and contribute to difficulties during thicknessing.

An excessive depth of cut can also place considerable strain on the machine.

It is therefore important to distinguish a genuinely defective component from an adjustment or operating problem.

Never force a wooden workpiece through the machine when the feed mechanism is malfunctioning.

Your Holzmann HOB305PRO Is Losing Power: How to Identify the Cause

A loss of power can have several causes.

It does not automatically mean that the motor needs replacing.

A transmission problem, a slipping belt, blunt blades or excessive cutting loads can affect the machine's performance.

Start by observing the symptoms without dismantling or working on the machine while it is running.

If the motor operates but movement is not transmitted correctly to the cutterblock, the transmission system may be responsible.

If the machine struggles mainly during cutting, check the condition of the blades and the cutting conditions.

An electrical supply problem can also cause abnormal operation.

Electrical inspections must be entrusted to a qualified person.

Do not automatically replace the motor or fuses without first identifying the cause of the problem.

A targeted repair helps avoid purchasing an unnecessary part and addresses the actual cause of the failure.

Differences Between Holzmann HOB305PRO and HOB305PROSMW2

The Holzmann HOB305PRO and HOB305PROSMW2 belong to the same family of planer thicknessers, but there is an important difference in their cutterblock design.

The conventional HOB305PRO is equipped with a cutterblock holding four 305 × 25 × 3 mm planer blades.

The HOB305PROSMW2 features a helical cutterblock equipped with carbide inserts.

Their cutting components and fastening systems are therefore different.

Conventional HOB305PRO blades cannot replace the carbide inserts fitted to the HOB305PROSMW2.

Likewise, the fastening components specific to each cutterblock must be identified separately.

Certain other components may be shared, such as the V-belt offered in our category, but this compatibility must never be generalised.

Before ordering, check your machine's complete model designation.

Spare Parts Compatibility Between 230 V and 400 V Versions

The Holzmann HOB305PRO is available in 230 V and 400 V versions.

Certain mechanical components may be shared by both versions, but electrical components require particular attention.

Motors, control devices and protective components may have different specifications depending on the power supply.

Before ordering an electrical part, record the information shown on your machine's identification plate and on the original component.

In particular, check:

• Supply voltage.

• Rated current.

• Manufacturer's references.

• Component specifications.

• List of compatible machines.

Never order an electrical component solely because it is described as suitable for the HOB305PRO.

The voltage and exact machine version must also be taken into account.

How to Identify the Correct Spare Part for Holzmann HOB305PRO

Before ordering a component, start by identifying your machine precisely.

The information on its identification plate is essential.

Record the following details:

• Brand: Holzmann.

• Exact model: HOB305PRO.

• Voltage: 230 V or 400 V.

• Serial number.

• Month and year of manufacture, where indicated.

• Part position on the exploded parts diagram.

• Manufacturer's reference.

• Dimensions of the original component.

For a planer blade, check the 305 × 25 × 3 mm dimensions.

For a clamping wedge, check its length and fastening system.

For a screw, check the thread, length and head shape.

For a fuse, check its current rating and other electrical specifications.

For the drive wheel, identify position 312, the 264 mm diameter and the approximately 27.8 mm bore.

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.

Visual similarity alone is not sufficient to guarantee that a component is compatible.

Maintain Your Holzmann HOB305PRO Planer Thicknesser Regularly

Regular maintenance helps preserve your machine's operation and identify signs of wear before they cause a breakdown.

Before any maintenance work, switch off and unplug the machine, and wait until all moving components have come to a complete stop.

Regularly inspect the planer blades and check their cutting performance.

Also check the feed mechanism and the condition of the transmission components.

Belts should be inspected for cracks or other damage.

Protective devices must remain in perfect working condition.

The cutterblock guard must be correctly positioned before every use.

The dust extraction system should also be maintained to limit the accumulation of wood chips inside the machine.

Use a dust collector suitable for your equipment's specifications.

Finally, pay attention to unusual noises, vibrations and adjustment difficulties.

These symptoms may indicate a fault requiring inspection before work continues.

Repair Your Holzmann HOB305PRO Instead of Replacing the Entire Machine

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

A damaged planer blade, defective clamping wedge, worn belt, faulty fuse or damaged drive wheel can be replaced individually when a compatible spare part is available.

However, an effective repair requires identifying the cause of the failure.

A broken belt may result from a mechanical blockage.

A blown fuse may indicate an electrical fault.

Blades that become blunt unusually quickly may require a review of the operating conditions and materials being machined.

A drive mechanism that operates irregularly should be inspected before replacing components at random.

An appropriate repair allows you to retain parts that are still functional and extend the service life of your equipment.
