The Bernardo PT305 planer thicknesser is a woodworking machine designed for surface planing and thicknessing solid timber. With its 305 mm working width, it allows woodworkers to flatten timber faces, straighten edges and produce workpieces with a consistent thickness.
Like any woodworking machine, it contains mechanical and electrical components that may become worn over time.
A damaged drive belt, worn feed roller, faulty switch or blunt planer knives can affect machine performance and the quality of the finished work.
At Probois Machinoutils, we offer a selection of spare parts for the Bernardo PT305 planer thicknesser, helping you maintain your machine, replace damaged components and extend its service life.
In this category, you will find drive belts, an electric motor, planer knives, a feed roller, a motor pulley, a switch, knife clamping wedges, fixing screws, a chip collector and protective components.
The 711J5 drive belt, also identified as 5PJ711, is an essential component of the Bernardo PT305 transmission system.
It transfers movement between the mechanical components specified by the manufacturer.
This Poly-V belt features 5 longitudinal ribs, allowing it to run on the appropriate pulleys.
It is offered for several compatible planer thicknessers, including:
Bernardo PT305.
Zipper ZI-HB305.
Scheppach HMS1250.
A worn belt may cause unusual noises, slipping, vibrations or loss of power during operation.
If your planer thicknesser develops these symptoms, we recommend checking the belt before considering the replacement of other components.
To order the correct reference, check the markings on the original belt and its position in the machine's exploded parts diagram.
We also offer the 559J4 Poly-V belt, intended for several compatible machines, including the Bernardo PT305.
This belt features 4 ribs, making it different from the 5-rib 711J5 belt.
It is also offered for selected machines from the following brands:
Zipper, including the ZI-HB305.
Scheppach, including the HMS1250.
Lurem.
Woodstar, including the PT106.
These two belts are not interchangeable. They have different dimensions and profiles and are designed for specific positions within the machine.
Before ordering a replacement belt, it is essential to check its exact reference.
Replacing a defective belt can restore smooth transmission when the belt is the actual cause of the problem.
The Bernardo PT305 motor provides the power required to drive the cutting and transmission mechanisms.
We offer an 1800 W single-phase replacement motor, intended particularly for the following planer thicknessers:
Bernardo PT305.
Zipper ZI-HB305.
Scheppach HMS1250.
Motor replacement may be necessary when an electrical or mechanical fault has been confirmed.
However, a motor that no longer starts is not necessarily beyond repair.
Before ordering a new motor, it is advisable to check the electrical supply, switch, starting components and any possible mechanical obstructions.
A damaged drive belt, blunt planer knives or an excessive depth of cut can also make the motor appear to lack power.
A preliminary diagnosis helps avoid the unnecessary replacement of an expensive component.
The KJD12 10 A switch is an electrical component used to control the starting and stopping of certain planer thicknessers.
Our catalogue includes a single-phase KJD12 switch with an emergency stop device, compatible in particular with:
Bernardo PT305.
Zipper ZI-HB305.
Zipper ZI-HB204.
A defective switch may prevent the machine from starting or interfere with its operation.
Symptoms may include failure to start, a switch that will not remain engaged or a damaged push-button mechanism.
However, starting problems should not automatically be attributed to the switch.
Other electrical components must also be checked.
All work on the electrical circuit must be carried out with the machine disconnected from the power supply and by a suitably qualified person.
The 305 mm planer knives play an essential role in the cutting quality of the Bernardo PT305.
They remove material to produce a flat, even surface during surface planing and thicknessing operations.
We offer 305 mm planer knives for the Bernardo PT305 and Zipper HB305.
Knives in good condition provide a better surface finish and help reduce the load placed on the motor.
Conversely, blunt or damaged knives may cause:
Torn wood fibres.
Marks on machined surfaces.
An uneven finish.
Increased cutting resistance.
Vibrations or unusual noises.
Before replacing the knives, check their exact dimensions and fixing system.
After installation, the knives must be adjusted in accordance with the manufacturer's instructions.
The planer knife clamping wedges secure the planer knives in their slots on the cutterblock.
These components are essential for ensuring that the cutting tools are correctly fixed.
We offer a set of 2 knife clamping wedges, corresponding to position 106 in the exploded parts diagram, for the following machines:
Bernardo PT305.
Zipper ZI-HB305.
A clamping wedge that is bent, cracked or has damaged contact surfaces may compromise the secure fixing of the knife.
When working on the cutterblock, it is important to inspect both the wedges and their fixing screws.
An incorrectly secured planer knife represents a serious safety risk during machine operation.
It is therefore essential to use suitable replacement parts and follow the manufacturer's installation procedure.
The planer knife clamping screws secure the clamping wedges to the cutterblock.
Our catalogue includes M6 x 16 mm screws, intended particularly for the following planer thicknessers:
Bernardo PT305.
Zipper ZI-HB305.
Zipper ZI-HB204.
A screw with damaged threads, a worn head or an inability to provide proper clamping must be replaced with a suitable reference.
Using a screw with a different length or specification is not recommended unless its compatibility has been confirmed.
Incorrect clamping may compromise the safety of the cutterblock assembly.
The Bernardo PT305 feed roller helps move timber through the machine during thicknessing operations.
It ensures that workpieces advance smoothly and consistently.
We offer a feed roller corresponding to position 95 in the exploded parts diagram, intended for:
Bernardo PT305.
Zipper ZI-HB305.
A worn or damaged roller may cause feeding difficulties, irregular movement or marks on the timber.
However, feeding problems do not necessarily originate from the roller itself.
They may also be caused by dirt accumulation, transmission problems, an excessive depth of cut or incorrect adjustments.
Before replacing the roller, we therefore recommend checking the feeding mechanism and the machine's operating conditions.
The motor pulley transfers movement between the motor and the driven mechanisms.
We offer a motor pulley, reference 3902203013, intended for several compatible planer thicknessers from Scheppach, Bernardo and Zipper.
A damaged or misaligned pulley may cause:
Premature drive belt wear.
Unusual vibrations.
Mechanical noises.
Poor transmission performance.
Before replacing a pulley, it is important to check the condition of the belt and the alignment of the various components.
The dimensions, bore diameter and fixing system of the original pulley must also be checked.
The Bernardo PT305 chip collector helps direct the wood shavings produced during surface planing and thicknessing towards the machine's chip removal system.
We offer a chip collector, reference 10001313, intended for the following planer thicknessers:
Bernardo PT305.
Zipper ZI-HB305.
A damaged or incorrectly positioned chip collector may interfere with chip removal.
An accumulation of wood shavings may also obstruct certain mechanisms or affect the cleanliness of the working area.
It is therefore important to keep the chip removal ducts and components clean and in good condition.
The collector must be correctly installed before using the machine.
The Bernardo PT305 adjustment handle is one of the components used to operate or adjust a mechanism on the machine.
We offer an adjustment handle, reference 1000968, corresponding to position 23 in the exploded parts diagram, for:
Bernardo PT305.
Zipper ZI-HB305.
A broken or cracked handle, or one with a damaged fixing system, may make certain adjustments difficult.
Before replacing the entire mechanism, it may be useful to check whether only the handle is defective.
The position number in the exploded parts diagram helps identify the exact component required.
The bridge guard is an essential safety device on a planer thicknesser.
It covers the unused section of the cutterblock during surface planing operations.
We offer a bridge guard arm, reference 10001554, intended for:
Bernardo PT305.
Zipper ZI-HB305.
This arm helps support and position the protective device.
A broken, bent or incorrectly secured arm may prevent the guard from functioning properly.
Damaged safety components must be repaired or replaced before the machine is used again.
A planer thicknesser must never be operated with a missing, damaged or disabled cutterblock guard.
Certain Bernardo PT305 spare parts are also compatible with other planer thicknessers of similar design.
Several references in this category are offered for the Zipper ZI-HB305, including planer knives, the motor, drive belts, feed roller, clamping wedges, screws and selected accessories.
Other components, such as certain drive belts and the motor, are also offered for the Scheppach HMS1250.
Depending on the reference, compatibility may also exist with selected Lurem, Woodstar or other Zipper machines.
However, a spare part compatible with the Bernardo PT305 is not automatically suitable for all these machines.
Specifications and mounting systems may vary depending on the model and manufacturing version.
It is therefore essential to check the compatibility information provided on each individual product page.
Regular maintenance helps preserve the performance of your Bernardo PT305 planer thicknesser and reduces the risk of breakdowns.
We recommend the following checks:
Inspect the drive belts for cracks, wear or signs of slipping.
Check the condition of the planer knives and sharpen or replace them when necessary.
Clean the working tables to remove wood shavings and resin deposits.
Inspect the feed roller to maintain consistent timber feeding.
Check the motor pulley for abnormal wear.
Clean the chip collector and keep the chip removal ducts clear.
Inspect the knife clamping wedges and screws when servicing the cutterblock.
Check the bridge guard and safety devices before each use.
Adjust the depth of cut according to the width and hardness of the timber.
A worn belt may cause power loss, while blunt planer knives increase the cutting effort required.
Similarly, incorrect adjustments or an accumulation of wood shavings may interfere with machine operation even when no component is defective.
Before carrying out any maintenance or repair work, the machine must be switched off and completely disconnected from the electrical supply.
When ordering a spare part for the Bernardo PT305, it is important to identify the required component accurately.
