Wear safety shoes and close-fitting clothes when working with this device.
Only use the machine outdoors.
Wear protective gloves.
Never split angle-cut wood.
Keep the work area free of chips and wood residues.
Shut the drive down before removing any jammed pieces of wood.

Safety instructions for rope winches
The rope winch may only be used when the machine is connected to the three-point linkage
of the tractor!
Ensure that the rope is not pulled over sharp edges!
Never guide the rope by hand whilst reeling it in!
Noise
The workplace-related, A-rated emission sound pressure level is 70 dB(A), measured at the
operative's ear.
In the case of machines with a PTO drive, the noise level depends on the noise of the tractor.
The stated values are emissions values, and thus do not necessarily represent reliable
values for the work area. Although there is a correlation between emission and pollutant
levels, it is not possible to deduce reliably from that whether or not additional precautionary
measures are necessary. Factors that influence the level of pollutants present in the work
area include the individual nature of the work area, other sources of noise, e.g. the number
of machines and other work operations being carried out in the vicinity. Equally, permissible
values for a work area may vary between different countries. However, this information
should enable the user to estimate the dangers and risks more accurately.
Remaining risks
Even if all safety precautions are observed and the machine is used in accordance with the
instructions, some risks still remain:
▪ Touching of revolving parts or tools.
▪ Injury caused by flying logs or log pieces.
▪ Risk of burns if the engine is not properly ventilated.
▪ Hearing loss if ear protection is not worn when working.
▪ Human error (e.g. due to excessive physical exertion, mental strain, etc.)
With every machine, some risks still remain. Therefore you should always be very careful
when working. It is up to the operating personnel to ensure that work is carried out safely.

Driven by tractor via universal joint shaft (type
PZG)
▪ Assemble the machine on the three-point linkage of the tractor.
▪ Attach the universal joint shaft and secure with the safety chain.
▪ Clockwise rotation of the tractor PTO shaft.
▪ Turn the tractor's manual throttle to minimum.
▪ Slowly engage the tractor PTO shaft and allow the machine to start moving.
▪ Set the required PTO speed using the manual throttle.
Maximum PTO shaft speed:
▪ 300 rpm (by model LH)
▪ 380 rpm
The maximum PTO shaft speed must on no account be exceeded, otherwise the oil will
become too hot. This leads to premature wear and leaks in the pump, cylinder and hydraulic
pipes.
Before disengaging the universal joint shaft, set the manual throttle of the tractor to
minimum.
The universal joint shaft must be stored in the universal joint shaft linkage when it is
disconnected.
Driven by the tractor's hydraulic system (type PS)
▪ Assemble the machine on the three-point linkage of the tractor.
▪ Connect the hydraulic hoses to the tractor's hydraulic system.
▪ Turn the control valve on the tractor to the "On" position.
Ensure that the viscosity of the tractor hydraulic oil is compatible with that of the splitter.
▪ Hydraulic oil HLP M46
Observe the flow and return.

Driven by tractor with shaft-mounted pump (type
PZ)
1. Assemble the machine on the three-point linkage of the tractor.
2. Attach the transmission to the tractor PTO shaft and secure with the chain to prevent
twisting.
– The chain must not be more than 30° to the vertical.
– The transmission must not lean more than 45° from the vertical, otherwise oil may
escape from the ventilation screw.
3. Clockwise rotation of the tractor PTO shaft.
4. Turn the tractor's manual throttle to minimum.
5. Slowly engage the tractor PTO shaft and allow the machine to start moving.
6. Set the required PTO speed using the manual throttle.
Maximum PTO speed:
▪ 380 rpm
The maximum PTO speed must on no account be exceeded, otherwise the oil will become
too hot. This leads to premature wear and leaks in the pump, cylinder and hydraulic pipes.
Before disengaging the universal joint shaft, set the manual throttle of the tractor to
minimum.

Operation
At outdoor temperatures below 0°C, let the machine idle for approximately five minutes
to allow the hydraulic system to reach the correct operating temperature (the hydraulic pipes
will then be warm to the touch).
"Autospeed"
"Autospeed" enables pressure-controlled switching between the two feed speeds.
▪ "Autospeed" responds to the required splitting pressure and automatically adjusts the
splitting speed.
The advantages:
Automatic pressure-controlled switching between the two feed speeds gives a faster
working speed.
▪ This in turn leads to a 30% increase in splitting performance.
The smooth, gentle switchover ensures the minimum of hydraulic wear.
Position Function
0Control levers in home position, splitting tool does not move.
IBoth control levers pressed downwards simultaneously. As long as the
control levers remain in this position, the splitting tool continues to
extend.
▪ The splitting speed is matched to the splitting pressure.
II If both control levers are pressed upwards simultaneously, the splitting
tool returns to its home position and then goes back to position "0".
In the case of switched off machines with "Autospeed", the splitting tool can fall
independently.
This slow fall is caused by the "Autospeed" valve and thus normal status.

▪ Place the log upright under the splitting knife and press it against the timber holder tip
so that even relatively thin logs stand without needing to be held.
▪ Pull both control levers downwards at the same time.
– The splitting knife advances and splits the log.
– As soon as the control levers are released, the splitting knife halts.
▪ Press the two control levers upwards to retract the splitting knife again.
▪ The return stroke of the splitting blade can be changed using the shut-off rod.
– Loosen the wing nut and push the shut-off rod into the desired position.
If the wood presses against the guard bracket during the splitting process, the guard
bracket jumps out of the detent position and swings downwards. This means that the guard
bracket is not damaged.
Before starting a new splitting process, the guard bracket must be pressed back up again
into the working position.
