2 PRODUCT DESCRIPTION
2.1 Designated use
The log splitter is intended exclusively for splitting
perpendicularly cut 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 op-
erated only by one person.
This appliance is intended solely for use in non-
commercial applications. Any other use as well
as unauthorised conversions or modifications are
regarded as contrary to the intended use and will
result in voiding of the warranty as well as loss of
conformity; the manufacturer will thus decline any
responsibility for damage and/or injury suffered
by the user or third parties.
2.2 Possible foreseeable misuse
The following applications are expressly forbid-
den:
■Splitting of logs in which metal parts such as
nails, wire, staples, etc. are embedded.
■Operation by more than one person
■Operation in a potentially explosive atmo-
sphere
Use for any other purpose that the designated
use is forbidden.
2.3 Residual risks
Even during correct use of the appliance, there is
always a certain residual risk that cannot be ex-
cluded. Depending on the use, the following po-
tential risks may arise from the type and con-
struction of the appliance.
Danger of serious injury from:
■Shattering logs and flying pieces of wood
during splitting
■Falling logs
■Tipping of the appliance
2.4 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 de-
vices repaired.
■Never disable safety and protective devices.
2.4.1 Motor protection switch
The motor protection switch switches off the mo-
tor if the log splitter is overloaded.
Do not deactivate the function of the motor pro-
tection 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.
2.4.2 Two-hand operation
The log pusher moves only when the ON button
and control lever are actuated simultaneously.
This avoids the risk of the operator’s hands being
in the danger area.
2.4.3 Protective cover
The protective cover prevents the hands of the
operator or of another person getting into the
splitting area during the splitting process.
2.4.4 Anchoring to the ground
Anchoring to the ground prevents the log splitter
from tipping over and helps to avoid serious inju-
ries.

2.6 Electrical requirements
2.6.1 Mains connection
DANGER! Risk of electric shock if the log
splitter is operated without residual current
circuit breaker. Operation of the appliance with-
out 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 leak-
age 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.

443281_a 17
Product description
■AC 230V / 50Hz
■Minimum fusing of the mains connection =
16A
2.6.2 Mains cable
WARNING! Risk of injury from electric
shock. A defective mains cable can result in seri-
ous 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
2.5mm².
■The maximum permissible cable length is
10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 ca-
ble (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.
