The Holzmann ZS560U is a drum sander designed for sanding and thicknessing large wooden workpieces. With a sanding width of 560 mm in a single pass, it can also handle workpieces up to approximately 1100 mm wide by turning the workpiece around. Its aluminium sanding drum and conveyor belt with adjustable feed speed provide consistent sanding and accurate thicknessing.

The machine operates on 230 V with a 1500 W main motor, while the conveyor system has its own feed motor. The feed speed is adjustable from 0 to 3 m/min, allowing the operator to adapt the feed rate to the type of wood, abrasive grit and sanding operation.

This category contains spare parts for the Holzmann ZS560U drum sander, including drive gears, motor, switch, transformer, electronic control board, conveyor feed components, protective and dust extraction parts, as well as sanding strips in various grit sizes.

Drive system parts for Holzmann ZS560U

The drive system plays an essential role in the operation of the drum sander. In particular, it ensures a smooth and consistent feed of the workpiece beneath the sanding drum.

Available parts include various drive gears for the Holzmann ZS560U, including gears identified as items 35 and 101, as well as the rubber ring associated with gear item 35.

These small mechanical components are subject to transmission forces and can gradually wear. Damaged teeth, excessive play or a worn gear can interfere with the feed system and cause irregular operation.

Before replacing the feed motor, it is therefore particularly important to inspect these mechanical components.

230 V motor for Holzmann ZS560U drum sander

The main motor is naturally one of the key components of the machine.

A 230 V single-phase motor compatible with the Holzmann ZS560U is available among the replacement parts. This motor may also be suitable for certain other drum sanders of similar design.

However, a machine fault does not automatically mean that the motor has failed. The power supply, switch, electrical connections and other components should be checked before replacing it.

Accurate troubleshooting helps avoid unnecessarily replacing an expensive component.

KJD16 switch for Holzmann ZS560U

The KJD16 switch is one of the electrical components that may require replacement after extensive use.

A faulty switch can prevent the machine from starting or cause irregular operation.

Before replacing it, however, the entire electrical supply should be checked to make sure that the switch is actually responsible for the fault.

Any work on electrical components must be carried out with the machine disconnected from the power supply and, where necessary, by a qualified person.

Transformer and electronic speed control board

The Holzmann ZS560U uses several electrical and electronic components for the operation of its feed system.

These include the transformer item 104 and the electronic speed control board item 117.

The control board helps regulate the conveyor feed speed. A fault in this component may therefore affect the adjustment or operation of the conveyor system.

However, the feed motor, electrical connections and mechanical drive components should also be checked before concluding that the electronic board is faulty.

Conveyor feed motor and electronic control unit

The conveyor belt speed of the ZS560U is adjustable, allowing the workpiece feed rate to be adapted to the sanding operation.

This category includes an electronic control unit with conveyor feed motor for 560 mm drum sanders.

This assembly is directly involved in the movement of the conveyor system. If the feed stops working, becomes irregular or no longer responds correctly to speed adjustment, this component may need to be inspected.

However, gears and other mechanical transmission components should not be overlooked, as they can cause similar symptoms.

Protective and dust extraction parts for Holzmann ZS560U

Sanding generates a considerable amount of fine dust. Efficient dust extraction is therefore essential for correct operation and helps keep the machine clean.

Available parts include various components for the protective and dust extraction hood for 560 mm drum sanders, including the hood itself, hinge, handle and certain locking components.

A damaged hood, broken hinge or faulty locking mechanism should be repaired to ensure that the machine's protective components remain in good condition.

The Holzmann ZS560U has a 100 mm dust extraction port and should be connected to a suitable dust extraction system during operation.

Sanding strips for Holzmann ZS560U drum sander

The ZS560U uses sanding strips designed for 560 mm drum sanders.

Several grit sizes are available, including 80, 100, 120 and 240 grit, allowing the sanding process to be adapted to the required result.

An 80 grit abrasive provides more aggressive material removal. Intermediate grits can be used for progressive sanding, while a finer grit such as 240 is better suited to finishing work.

Sanding strips for this type of machine are available in dimensions such as 3280 mm long and 77 mm wide, with a profile designed for correct installation around the sanding drum.

When should the ZS560U sanding strip be replaced?

The sanding strip is a consumable and should be replaced regularly.

A heavily clogged, worn or torn sanding strip, or one whose abrasive grains have lost their cutting efficiency, will reduce sanding performance. This may encourage the operator to remove too much material in a single pass, placing unnecessary strain on the machine.

Keeping the abrasive in good condition therefore helps achieve better sanding results while reducing unnecessary load on the motor and feed mechanism.

Regular use of an abrasive cleaning stick can also help extend the service life of sanding strips.

Why is the Holzmann ZS560U conveyor feed not working?

If the workpiece no longer feeds correctly beneath the sanding drum, there may be several possible causes.

Before replacing a component, it is advisable to inspect the transmission system, drive gears, feed motor, electronic speed control board, transformer and electrical connections.

An irregular feed therefore does not necessarily mean that the conveyor feed motor is faulty.

In some cases, a damaged drive gear alone may be enough to disrupt the operation of the mechanism.

Check the item numbers on the ZS560U exploded diagram

To accurately identify a Holzmann ZS560U spare part, the machine's exploded diagram is particularly useful.

Certain components are identified directly by their item numbers, such as drive gear item 35, drive gear item 101, transformer item 104 and speed control board item 117.

Checking the item number against the spare part listed on our website helps identify the correct component and reduces the risk of ordering the wrong part.

Some parts are compatible with several drum sanders

Several components available for the Holzmann ZS560U may also be suitable for other drum sanders of similar design.

This is particularly true for certain electrical, mechanical and protective components. 560 mm sanding strips may also be suitable for other machines using the same dimensions.

However, this does not mean that all parts are interchangeable.

IMPORTANT: BEFORE PURCHASING, always check the list of compatible machines shown on the product page and, where required, the month and year of manufacture or the serial number of your machine.

Visual similarity between two components does not guarantee compatibility.

Maintain your Holzmann ZS560U drum sander

A drum sander produces a large amount of dust and therefore requires regular maintenance.

Keep the dust extraction system clean and efficient, remove accumulated sanding dust from around the mechanisms and periodically inspect the condition of the drive components.

The sanding drum, feed system and transmission components should operate freely without abnormal mechanical noise.

It is also advisable to replace worn sanding strips promptly to avoid placing unnecessary strain on the machine.

Before carrying out any maintenance, inspection or repair, always disconnect the Holzmann ZS560U from the power supply.

Repair your Holzmann ZS560U with the correct spare part

An electrical fault, conveyor feed problem or damaged gear does not necessarily mean that the entire drum sander needs to be replaced.

Our selection of spare parts for the Holzmann ZS560U drum sander allows many components to be replaced individually, including drive gears, motor, KJD16 switch, transformer, electronic control board, conveyor feed motor, protective and dust extraction components, and 560 mm sanding strips.

Correctly identifying the cause of the fault and the required spare part before ordering is the best way to repair your Holzmann ZS560U and extend its service life.
