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.

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 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 90

0

.

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 90

0

to
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

7

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.

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.

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.

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 2.5mm

2

and
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 (230V/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.

ASSEMBLY AND OPERATION

Warning! For your own safety, do not connect the log splitter to the power source until the
machine is completely assembled and you read and understand the entire instruction
manual.

Warning! For your own safety, never forget to bolt the support leg to the log splitter, lift the
log splitter by the handles at both ends and place it on a 60-75cm high, stable, flat and level
work surface.

Warning! Never use the log splitter if it is not in perfect order or if it needs servicing. Before
starting work, check correct functioning of all the safety devices (ZHB, push button).

Assembly

1. Before operating the log splitter, it is
necessary to fit the rolling wheel (2) Fig. 2,
on supporting shaft (1) as shown. Insert
the wheels on the shaft, block it using the
washer (3), and fasten by the lock nut (4).

2. Assemble the supporting leg on the
machine body, use the two bolts, elastic
washers and flat washers to fasten the
supporting leg on the machine body.

Fig. 2

11

3. Use two screws, elastic washers and flat
washers to fasten the safety guard on the
supporting bracket to protect the ZHB
hydraulic control lever.

4. Turn the rubber knob onto the ZHB
hydraulic control lever for comfortable
operation.

Operation

Warning! Before operating the log splitter,
the Bleed Screw (13) Fig. 3, 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. 3

DO NOT ADJUST THE MAX PRESSURE
LITITING SCREW (14) IN FIG. 4!

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. 4, and never to loose and adjust it.

Fig. 4

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.

5. 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

13

12

12

excessively hard wood.

Fig. 5

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 90

0

to 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.

Fig. 6

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.

Fig. 7

Do not try to knock the jammed log off.
Knocking will damaged the machine or

13

may launch the log and cause accident.

Fig. 8

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.

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.
