The log splitter is intended exclusively for splitting perpendicularly cut and well-dried logs. The dimensions of the logs must not exceed the dimensions given in the technical data. Only one person may remain in the working area of the log splitter, and the log splitter may be operated only by one person. This appliance 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.

Splitting of logs in which metal parts such as nails, wire, staples, etc. are embedded if forbidden.

Operation in a potentially explosive atmosphere is forbidden.

Use for any other purpose that the designated use is forbidden.GB

2.3 Safety and protective devices

WARNING! Risk of injury Defective and disabled safety and protective devices can lead to serious injury.

Have any defective safety and protective devices repaired.

Never disable safety and protective devices.

2.3.1 Motor protection switch

The motor protection switch switches off the motor if the log splitter is overloaded. Do not deactivate the function of the motor protection switch. If the motor protection switch has switched off the log splitter, proceed as follows:

1. Disconnect the log splitter from the mains.

2. Determine the cause of the overload.

3. Allow the log splitter to cool down for several

minutes, then connect to the mains again.

4. Switch on the log splitter.

WARNING! Risk of injury from electric shock A defective mains cable can result in serious injuries due to electric shock.

Ensure that the mains cable is not damaged or severed.

Use only rubber-sheathed cables of quality H07RN-F according to VDE 0282 Part 14 with a conductor cross section of at least 2.5mm².

The maximum permissible cable length is 10m. 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, cuts, crushed or kinked points in the insulation) must not be used.

Repairs to the mains cable, mains plug and coupling socket may only to be carried out by qualified electricians.

Do not expose plug connectors to moisture.

If the mains cable is damaged, immediately disconnect it from the mains.

3.6 Electrical safety

The connection plug of the power tool must fit into the socket. The plug is not allowed to be changed in any way. Do not use any plug adapters together with earthed power tools. Unmodified plugs and matching sockets reduce the risk of electric shock.

Avoid physical contact with earthed surfaces such as on pipes, heaters, cookersGB

34 KHS 3704 | KHS 5204 | KHS 8552

Safety instructions and refrigerators. There is an increased risk of electric shock if your body is earthed.

Keep electrical tools out of the rain and away from moisture. Water getting into an electrical tool increases the risk of an electric shock.

Do not use the connection cable for incorrect purposes such as carrying the electrical tool, hanging it up or for pulling the plug out of the socket. Keep the connection cable away from heat, oil, sharp edges and moving parts. Damaged or tangled connection cables increase the risk of electric shock.

If you are working outside with a power tool, only use extension cables that are also suitable for outside. Using an extension cable that is suitable for outside decreases the risk of electric shock.

If the operation of the power tool in a humid environment cannot be avoided, use a fault current circuit breaker. Using a fault current circuit breaker decreases the risk of electric shock.

3.7 Use and handling of the

Do not overload the power tool. Use the appropriate power tool for the job you are doing. Using the appropriate power tool will enable you to work more effectively and safely in the specified performance range.

Do not use a power tool if it has a defective switch. A power tool that can no longer be switched on or off is dangerous and must be repaired.

Disconnect the plug from the socket and/or remove the battery before you make adjustments to the appliance, replace parts or put the power tool away. This precautionary measure will prevent the power tool from starting inadvertently.

Keep unused power tools out of the reach of children. Do not allow people to use the power tool if they are not familiar with it or have not read these instructions. Power tools are dangerous if they are used by inexperienced people.462706_l 35 Safety instructions

Look after power tools and the insertion tool with care. Check whether moving parts function perfectly and do not stick, whether there are any broken parts or parts that are damaged in such a way that the function of the power tool is impaired. Have damaged parts repaired before using the power tool. Many accidents are caused by failure to maintain power tools properly.

Keep cutting tools sharp and clean. Carefully maintained cutting tools with sharper cutting edges are less likely to stick and are easier to control.

Use power tools, accessories, insertion tools, etc. according to these instructions. When doing so, take account of the working conditions and the activity to be undertaken. Using power tools for applications other than the intended purpose can result in dangerous situations.

Keep the grips and grip surfaces dry, clean and free from oil and grease. Slippery grips and grip surfaces prevent safe operation and control of the power tool in unforeseen situations.
