SPECIAL SAFETY INSTRUCTIONS FOR LOG SPLITTER
1. The log splitter must always be used by one operator only.
2. Nobody must be allowed to use the log splitter unless they have read the instruction manual
and have been instructed in the regulations to follow for correct and safe use.
Operators must receive necessary training and instructions.
3. The machine must be used by adults only. Use of the log splitter by apprentices of not less
than 16 years of age must be supervised by an adult authorized to use the machine.
4. Never wear loose, unbuttoned clothing which may become trapped in moving parts.
5. Position the machine on a support surface of 60-75 cm height, free from any objects that could
prevent complete freedom of movement for the operator while working. The surface must be
perfectly leveled to prevent the machine from falling during operation.
6. It is prohibited to work with the machine on the ground. This is not only an uncomfortable
working position but it can also be dangerous because the operator has to bring his face close
to the machine, and thus risks being struck by chips or debris.
7. Check that the logs to be split are free from nails or wire, which may fly up or damage the
machine, the ends of the logs must be cut square, branches must be cut off flush with the
trunk.
8. Never try to split logs larger than those indicated in the technical specifications. This could be
dangerous and may damage the machine.
9. Break wood in the direction of the grain, do not place wood across the log splitter and leave it
in that position for splitting; it may be dangerous and may seriously damage the machine.
10. Never attempt to cut two logs at once, one may fly up and hit you.
11. If the log moves away from the blade, retract the ram or the blade and turn the log through 900.
12. Do not attempt to load the log in the log splitter while the ram is in motion, you could get
trapped and injured.
13. Keep your hands well away from any splits and cracks which open in the log; these may close
suddenly and crush or amputate your fingers.
14. Never force the log splitter for more than 5 seconds keeping the cylinder under pressure in the
attempt to split excessively hard wood. After this time interval, the oil under pressure is
overheated and the machine could be damaged. It is thus better to stop and rotate the log by
900to see whether it can be split in a different position. In any case, if you are not able to split
the log, this means that its hardness exceeds the capacity of the machine and thus that log
should be discarded so as not to damage the lop splitter.
15. Do not force the blade by pushing the log on the upper part, as this can cause the blade to
break or damage the body of the machine. Always set the log on the guides.
16. Never leave the machine unattended while it is running. If you leave the machine, even for a
short time, remove the power supply or any possible cause of accidental start-up.
17. The log splitter must never be used by an operator who is under the influence of alcohol, drugs,
medicines, or who is tired. A clear mind is essential for safety.
18. Never request the assistance of another person to help you remove a jammed log.
19. Do not use machines with electric motor if natural gas, petrol fumes or other inflammable
vapours are present.

7
20. Check that the electric circuit is adequately protected and that it corresponds with the power,
voltage and frequency of the motor, check that there is a ground connection, and a regulation
differential switch upstream.
Check on the functioning of the machine.
21. Never open the switch box on the motor. Should this be necessary, contact a qualified
electrician.
22. Make sure that the machine and the cable never come in contact with water.
23. Treat the power cable with care, do not attempt to move the machine by pulling the cable, do
not yank the cable to unplug it; keep the cable away from excessive heat, oil and sharp
objects.
24. Never leave the machine unattended with the power supply “on”, also disconnect the power
cable when not in use, when carrying out maintenance work, when changing attachment or
moving the machine.
25. Before starting work, hydraulic pipes and hoses shall be inspected and the stopping devices
shall be tested.
26. Keep the working area free from obstructions, e.g. logs, split wood etc.
27. Stop the machine before cleaning or making adjustments.
28. The hazards may arise from particular characteristics of wood when being split(e.g.knots, logs
of irregular shape etc.)

WARNING! Connect the main leads to a
standard 240V±10% (50Hz±1Hz) electrical
supply which has protection devices of
under-voltage, over-voltage, over-current
as well as a residual current device (RCD)
which maximum residual current rated at
30mA.
Replacing cables or plugs
Immediately throw away old cables or plugs
when they have been replaced by new ones. It
is dangerous to insert the plug of a loose cable
in the wall outlet.
Using extension cables
1. As a supply for this machine always use
an unloaded line and/or extension with
conductor of at least 2.5mm2and
protected with a 20A fuse. Be sure that
this extension cable is not longer than 10
meters. Excessively long cables or
inadequate section can cause voltage
drops that prevent motor from developing
its full power.
2. Only connect your machine and/or
extension cable to an earthed electricity
mains.
3. This machine can be switched to the
single-phase network (240V/50Hz), if you
are in doubt about the earth of the
electricity provisions, consult an electrician
first.
Grounding
In the event of an electrical short circuit,
grounding reduces the risk of electric shock by
providing a path of least resistance to disperse
electric current. This machine is equipped with
a power cord having a equipment-grounding
prong
1. Reduce the risk of electrocution by
keeping all connections dry and off the
ground. Do not touch plugs with wet hands.
Failure to follow these warning could result
in serious injuries.
2. This machine must have a ground prong
in the plug to help ensure that it is
grounded. Do not remove ground prong
from plug to fit into a two-pronged outlet! If
the plug will not fit the outlet, have the
proper outlet installed by a qualified
electrician.
UNPACKING
WARNING! To prevent accidental starting that
could cause possible serious personal injury,
assemble all parts to your log splitter before
connecting it to power supply. Log splitter
should never be connected to power supply
when you are assembling parts, making
adjustments, installing or removing drill bit, or
when not in use.
zCarefully remove all parts from the carton
and place the log splitter on a level work
surface of the height not less than 60cm.
Separate and check against the list of
loose parts.
WARNING! If any parts are missing, do not
operate this machine until the missing parts
are replaced. Failure to do so could result in
serious personal injury.
zDo not discard the packing materials until

2. Size of the logs to be split
The figure 1 shows the maximum log sizes
that can be split.
The diameter of the log is indicative: a small
log can be difficult to split if it has knots or a
particularly tough fiber. On the other hand, if
the wood has regular fibers it is not difficult to
split logs with diameter greater than the
maximum shown in fig. 1. It is important not
to insist when the log does not split on the
first attempt, as the pump may be damaged
by the overheating of the oil when the
machine is made to work under the
maximum stress in the attempt to split
excessively hard wood.
3. Recommended oils
We recommend use of the following oils for
the hydraulic cylinder.
SHELL TELLUS T22
ARAL VITAM GF22
SP ENERGOL HCP22
MOBILE DTE 11 OR equivalent
DO NOT USE OTHER GRADE OILS

Operation
Warning!
Before operating the log splitter, the Bleed
Screw (13) Fig. 16, should be loosened by
some rotations until air can go in and out
of the oil tank smoothly.
Air flow thru the Bleed Screw hole should
be detectable while the log splitter is under
operations.
Before moving the log splitter, make sure
the Bleed Screw is tightened to avoid oil
leaking from this point.
FAILED TO LOOSEN THE BLEED SCREW
WILL KEEP THE SEALED AIR IN
HYDRAULIC SYSTEM BEING
COMPRESSED AFTER BEING
DECOMPRESSED. SUCH CONTINUOUS
AIR COMPRESSION AND
DECOMPRESSION WILL BLOW OUT THE
SEALS OF THE HYDRAULIC SYSTEM AND
CAUSE PERMANENT DAMAGE TO THE
LOG SPLITTER.
Fig. 16
DO NOT ADJUST THE MAX PRESSURE
LITITING SCREW (14) IN FIG. 17!
Max pressure was set before the log
splitter ex work and the max pressure
limiting screw is tightened to ensure the
log splitter works under pressure no more
than 4 tons. The setting was done by
qualified mechanic with professional
instruments.
Unauthorized resetting will cause the
hydraulic pump fail to output enough
splitting pressure or RESULT IN SERIOUS
INJURY AS WELL AS DAMAGE TO THE
MACHINE.
The max pressure limiting screw is
protected by a plastic cap (15) as shown in
Fig. 17, and never to loose and adjust it.
Fig. 17
This log splitter is equipped with “ZHB” control
system that requires to be operated by both
hands of the user – left hand controls the
hydraulic control lever while right hand
controls the pushbutton switch as shown in Fig.
18. The log splitter will freeze upon absence of
either hand. Only after both hands release the
controls, the log pusher starts to return
backward to the starting position.
Never force the log splitter for more than 5
seconds by keeping pressure on it to split
excessively hard wood.

14
After this time interval, the oil under pressure
will be overheated and the machine could be
damaged. For such extremely hard log, rotate
it by 900to see whether it can be split in a
different direction. In any case, if you are not
able to split the log, this means that its
hardness exceeds the capacity of the machine
and thus that log should be discarded to
protect the log splitter.
NOTE: During operation, the metal part
connected to the motor remains cold or in any
case reaches a temperature only slightly
higher than the ambient temperature. After
several hours of use with particularly difficult
wood, the pump may become very hot. This is
not a dangerous situation for the machine,
which returns to full functioning capacity after
being cooled. On the other hand, it is very
important not to cause overheating of the oil,
and thus the pump, by forcing the machine in
an attempt to split logs that exceed the
capacity of the machine.
Always set logs firmly on the log retaining
plates and work table. Make sure logs will
not twist, rock or slip while being split. Do
not force the blade by splitting the log on
the upper part. This will break the blade or
damage the machine.
Break log in the direction of its grown grain. Do
not place log across the log splitter for splitting.
It may be dangerous and may seriously
damage the machine.
Do not attempt to split 2 pieces of logs at the
same time. One of them may fly up and hit
you.
Freeing a jammed log
1. Release both controls.
2. After the log pusher moves back and
completely stops at its starting position,
insert a wedge wood under the jammed
log.
3. Start the log splitter to push the wedge
wood to go completely under the jammed
one.
4. Repeat above procedure with sharper
slope wedge woods until the log is
completely free.
Do not try to knock the jammed log off.
Knocking will damaged the machine or
may launch the log and cause accident.
Replacing hydraulic oil
Replace the hydraulic oil in the log splitter after
every 150 hours of use. Take following steps
to replace it.
1. Make sure all moving parts stops and the
log splitter is unplugged.
2. Unscrew oil drain bolt with dipstick to
remove it.

15
3. Turn the log splitter on the motor side over
an 3 liters capacity container to drain the
hydraulic oil off.
4. Turn the log splitter on the support leg
side.
5. Refill fresh hydraulic oil at the volume as
per the hydraulic oil capacity of a particular
model indicated in the specifications table.
6. Clean the surface of Dipstick on the oil
drain bolt and put it back into the oil tank
while keep the log splitter vertically.
7. Make sure the level of the refilled oil is just
between 2 grooves around the dipstick.
8. Clean the oil drain bolt before thread them
back. Make sure they are tightened to
avoid leakage before placing the log
splitter horizontally.
Periodically check oil level to ensure it is
between 2 grooves around the dipstick.
Upon lower oil level, oil refilling is required.
Warning: Never mix oil with general waste!
Used oil must be disposed of according to
current regulations in the country where
the machine is used.
Sharpening the wedge
After using the log splitter for some time,
sharpen the wedge of the log splitter using a
fine-toothed file and smooth any burrs or
crushed area along the cutting edge.
