PRODUCT DESCRIPTION

3.1 Intended use
The machine is intended for the shredding of twigs and branches from trees and bushes with a maximum diameter of 40 mm. This trailer is intended solely for use in non-commercial applications. Any other use (as well as unauthorised conversions or add-ons) are regarded as contrary to the intended use and will result in exclusion of the warranty as well as loss of conformity (CE mark); the manufacturer will thus decline any responsibility for damage and/or injury suffered by the user or third parties.
P40: continuous operation with interruptions
The appliance can be operated continuously but with regular interruptions at high loads. If it is operated for too long at high loads, the overload protection switches the appliance off. The appliance has been tested and approved for operation at full load for 40 s followed by an idling time of 60 s.
3.2 Possible foreseeable misuse
■ The machine is not intended for commercial use or in agriculture and forestry.
■ Do not use the machine in rainy weather.
■ The safety devices on the machine must not be dismantled or bypassed.
3.3 Residual risks
Even during correct use of the appliance, there is always a certain residual risk that cannot be excluded. Depending on the use, the following po-tential risks can be derived from the type and construction of the appliance:
■ Injuries from flying cuttings
■ Injuries due to inhaling cutting particles
■ Injuries due to reaching into the shredder mechanism
■ Injuries due to the machine tipping over
3.4 Symbols on the machine

cable is damaged or cut.
| Switch off the engine before starting any work on the appliance.
| Wear protective glasses and ear defenders.
| Wear gloves.
| Protect against moisture.

3.5 Safety and protective devices
WARNING! Risk of injury. Defective and disabled safety and protective devices can result in serious injury.
■ Have any defective safety and protective devices repaired.
■ Never disable safety and protective devices.
Motor protection switch
The motor protection switch disconnects in the case of overload. Hereby, switch (07/3) pops out of the control panel. The switch can be pushed back in again after a cooling-down phase of approx. 5 minutes, and the machine can be switched on. If the switch does not remain by itself in the pressed position, extend the coolingdown phase. If the problem continues to exist, take the machine to a specialist workshop.
Restarting protection
For your safety, the machine is fitted with a 0 voltage switch, which automatically  witches off the machine in the case of a power interruption. Once the voltage supply is re-established, the machine does not restart automatically. Press the On switch (07/1) to restart.
Protection switch on the upper shredder part
The shredder upper section is equipped with a protection switch, which switches off if the closing screw (01/8) is loosened. The motor is thus prevented from unintentional starting.
The machine can only be switched on again when the housing (01/1) has been fitted and the closing screw tightened.
3.6 Electrical requirements
3.6.1 Mains connection
DANGER! Risk of electric shock if the log
splitter is operated without residual current circuit breaker. Operation of the appliance without residual current circuit breaker in the mains connection can result in serious injuries or even death due to electric shock.
■ Before connecting the appliance, check whether the mains connection has a residual current circuit breaker for a maximum leakage current of 0.03 A.
■ If you cannot be sure that a residual current circuit breaker is installed: Use an additional portable residual current device with switched PE conductor.
■ Mains voltage, see “Technical data”. Do not use any other mains voltage!
Only for Great Britain (240 V)!
■ This machine must be earth!
■ Never use a faulty power cable!
■ Check the power cable regularly for signs of wear and tear!
Wiring instructions:
When wiring the English 3 pin plug, please follow the instruction according to the colour coding as shown below:

WARNING! Risk of injury from electric shock. A defective mains cable can result in serious injuries due to electric shock.
■ Make sure that the mains cable is not damaged or severed.
■ Use only rubber-sheathed cables of quality H05RN-F according to DIN 57282, Part 817 / VDE 0282, Part 817 with a rubber-coated plug connector and a conductor cross section of at least 1.5 mm² (230 V: 3 x 1.5 mm², 400 V: 5 x 1.5 mm²). The cable must not be of a lighter type. For the United Kingdom only: rubbersheathed cables of type BS 6500 (1984), Table 16 PVC 3 core flex, 300/500 V HOS VV-F with a rubber-coated plug connector and a 13 A fuse.
■ The maximum permissible cable length is 50 m. A longer cable impairs the motor power and hence the performance and function of the log splitter.
■ Mains cable, mains plug and coupling socket must be undamaged. A defective mains cable (e.g. with cracks/fractures, cuts, crushed or kinked points in the insulation) must not be used.
■ Check the condition of your mains cable each time prior to use.
■ Protect the mains cable from heat and sharp edges. Do not expose plug connectors to moisture.
■ Do not pull on the mains cable to remove the mains plug from the socket.
■ If the mains cable is damaged, immediately disconnect it from the mains.
■ Repairs to the mains cable, mains plug and coupling socket may only to be carried out by qualified electricians.
