Hints

Large objects or pieces of wood may be removed after the shredder has been operated several times both in cutting and in release direction.

Use a tamper or hook to remove jammed objects from the hopper or ejection slot.

Always wait until the shredder has come to a completely stand still before restarting it.

Working with the garden shredder

• Choose a working position alongside the equipment or behind it. Never stand near the ejection opening.
• Provide a safe standing position and keep at any time the balance. Do not lean forward. When placing material into the shredder, always stand on the same level as the machine.
• Always keep away from the ejection area when starting the machine.
• Longer material that is protruding from the device could spring back when it is drawn in by the blades! Observe safety distance!
• Never reach into the filling or ejection opening.
• Keep your face and body away from the filling opening.
• Never place hands, other parts of the body or clothing into the filler funnel, ejection channel or in the vicinity of other moving parts.
• Check that no chopped residues are in the filling hopper before switching on the device.
• Do not tilt or transport the machine (relocation) while the motor is running.
• Make sure that the motor is free from waste material and other material accumulation to protect it against damage and to prevent fire.
• When filling, be careful that no pieces of metal, stones, bottles or other objects unintended for processing, enter the filling hopper.

• Power off the device before attaching or removing the collecting bag.

• Immediately switch off the equipment and allow it to come to a stop, if foreign objects enter the filling hopper or if the equipment starts to make unusual noises or vibrates. Remove the mains plug and carry out the following checks:

inspect for damage,
- replace or repair damaged parts,
- check the equipment and tighten loose parts.

You must not repair the equipment yourself if you are unauthorized to do so.

What can I shred?

Yes:

• all types of branches up to a max. diameter, depending on wood species and freshness.
• withered garden refuse which has lain a number of days.
  Only shred in alternation with branches.

No:

• glass, metal, plastic, plastic bags, stones, cloth, roots with soil
• refuse which does not have a solid consistency, e. g. kitchen waste

Special tips on shredding:

Always fill the material to be shredded into the filling hopper from the right.
- Branches, twigs and wood should be broken down immediately after they have been cut

Material of this kinds gets very hard when it is dry, and the maximum allowed branch diameter to be processed has to be reduced.

Remove any side shoots from branches with a large number of twigs.
How to shred garden and kitchen waste with hight water content and a tendency to clog
to prevent the machine from clogging, alternate waste with wood containing material.
Do not allow the shredded material to pile up too high in the area of the ejection opening. This can lead to shredded material blocking the ejection channel, and backing up to the filler opening.
Clean out the filler opening and ejection channel thoroughly if the machine becomes blocked. Before doing this, switch the motor off and disconnect the machine from the mains power supply.
Please do not exceed the maximum branch diameter specified (cutting fresh wood) for your appliance (see Technical data). Depending on the wood's nature and freshness the maximum branch diameter the machine can process may be smaller.
The cutter automatically draws the shredding material into the machine through the slow rotation of the cutting rollers.
Automatic switch-over in the direction of rotation:
If the unit suddenly clogs, the blades may start to turn in the opposite direction and push the shredded material back out.
Switch off unit

Wait until the blades come to a standstill
Switch unit back on and use material which is easier to process.
If the machine is overloaded, a protective motor switch ensures that the machine turns itself off automatically.

• Turn the shredder on again after about 5 minutes.
• If you cannot turn on the machine after this waiting time refer to „Operational faults".

Adjusting the fixed counter blade

It is possible to adjust the counter blade (B) at the cutting roller (A) free of clearance. For an effective operation, an as small as possible clearance should be maintained.

Soft material or wet branches may tear instead of being cut. A counter blade that is worn after repeated use may also lead to this problem.

Setting the clearance.

Switch on the device.

There is an adjustment device on the right hand side of the plastic housing. To adjust the distance turn the adjusting knob (D) clockwise so that the screw (C) moves toward the cutting roller. (A). Turn until fine aluminium chips are falling from the ejection slot.

Maintenance / Cleaning / Storage

Each time before starting maintenance work:

• Switch off the motor and pull out the mains plug.
• Allow the machine to cool down.

Risk of injury through moving hazardous parts.

Wear protective gloves in order to avoid injury to the hands.

When the machine is stopped for purpose of maintenance, storage or accessory replacement make sure that the energy source is isolated and the mains plug is disconnected. Make sure that all movable parts are stationary and the key (if applicable) is removed. Allow the machine to cool down before maintenance, adjustment etc.

The cutters will not come to a standstill immediately after cut-off. Before starting any service work wait until all parts are stationary.

When performing maintenance operations on the cutting tool be aware that it can still move due to the start

mechanism even if the motor does not run by the cover interlocking.

Be sure to have removed any tools from the machine after completion of service work.

• Generally garden shredders require little maintenance. To maintain their efficiency and a long life, observe the following:

• Keep vent slits clean and free from obstructions.

• Check the locking screws (tighten where necessary).
  Clean the device after shredding.

To clean your product only use a warm moist cloth and a soft brush.

Never use cleaning agents or solvents. Otherwise the device may be damaged irreversibly. Plastic parts may be corroded by chemicals.

• Do not clean the machine with running water or high-pressure cleaners.

• After each operation treat bare metal parts with an environment-compatible biodegradable spray oil to protect them against corrosion.

• the cutting roller and shaving plate are expendable parts, though with normal use and correct adjustment they have a service life of many years.

• Replace worn and damaged single parts as a whole set to prevent any unbalance.

Dislocation / Transport

Before each dislocation / transport

• Switch off device.
  Wait for standstill of the device.
  Pull out mains plug.

Dislocation:
