SAFETY WARNINGS & CAUTIONS
SYMBOL AFFIXED TO THE
MACHINE SAFETY WARNINGS & INSTRUCTIONS
 UNDERSTAND YOUR LOG SPLITTER
Read and understand the owner’s manual and labels
affixed to the log splitter. Learn its application and
limitations as well as the specific potential hazards
peculiar to it.
 INSPECT YOUR LOG SPLITTER
Check your log splitter before turning it on. Keep guards
in place and in working order. Form a habit of checking to
see that keys and adjusting wrenches are removed from
tool area before turning it on. Replace damaged, missing
or failed parts before using it.
 AVOID DANGEROUS CONDITIONS
Put the log splitter on a 60 - 75cm high, stable, flat, and
level work bench where there is plenty of room for
handling, and help the operator stay alert. Bolt the log
splitter to the work surface if it tends to slip, walk, or
slide. Keep your work area clean and well lighted.
Cluttered areas invites injuries.
Do not use the log splitter in wet or damp areas or expose
it to rain. Do not use it in areas where fumes from paint,
solvents or flammable liquids pose a potential hazard.
 DRUGS, ALCOHOL AND MEDICATION
Do not operate the log splitter while under the influence
of drugs, alcohol, or any medication that could affect your
ability to use it properly.
 INSPECT YOUR LOG
Make sure there are no nails or foreign objects in logs to
be split. The ends of the logs must be cut square.
Branches must be cut of flush with the trunk

PROTECT YOUR EYES AND FACE
Any log splitter may throw foreign objects into the eyes.
This can cause permanent eye damage. Always wear
safety goggles. Everyday eyeglasses have only impact

3
resistant lenses. They are not safety glasses. Do not put
the log splitter on the ground for operations. This is
awkward operating position that the operator has to bring
his face close to the machine, and thus risks being struck
by wood chips or debris
 EXTENSION CORDS
Improper use of extension cords may cause inefficient
operation of the log splitter which can result in
overheating. Be sure the extension cord is no longer than
10m and its section is no less than 2.5mm2to allow
sufficient current flow to the motor.
Avoid use of free and inadequately insulated connections.
Connections must be made with protected material
suitable for outdoor use.

AVOID ELECTRICAL SHOCK
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.
Ground the log splitter. Prevent body contact with
grounded surfaces: pipes, radiators, ranges, and
refrigerator enclosures.
Never open the pushbutton box on the motor. Should this
be necessary, contact a qualified electrician.
Mark sure your fingers do not touch the plug’s metal
prongs when plugging or unplugging the log splitter.
 KEEP VISITORS AND CHILDREN AWAY
The log splitter must be always operated by one person
only. Other people should keep a safe distance from the
work area, especially when the log splitter is under
operations. Never use another people to help you with
freeing jammed log.
 DRESS PROPERLY
Do not wear loose clothing, gloves, neckties or jewelry
(rings, wrist watches). They can be caught in moving
parts.
Protective electrically non conductive gloves and non-skid
footwear are recommended when working. Wear

LOG SPLITTER OPERATION

11
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. 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.
Trigger type lock-out device is adopted to avoid accidental Hydraulic Control
Lever pushdown. To operate the Hydraulic Control Lever, draw the Trigger
backward with the index finger before push the Hydraulic Control Lever forward.
Never force the log splitter for more than 5 seconds by keeping pressure

12
on it to split excessively hard wood.
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 90oto 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.
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 growing 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

13
 Release both controls.
 After the log pusher moves back
and completely stops at its starting
position, insert a wedge wood
under the jammed log.
 Start the log splitter to push the
wedge wood to go completely
under the jammed one.
 Repeat above procedure with
sharper slope wedge woods until
the log is completely freed.
Do not try to knock the jammed log
off. Knocking about will damage the
machine or may launch the log and
cause accident.
REPLACING HYDRAULIC OIL

14
Replace the Hydraulic oil in the log splitter after
every 150 hours of use. Take following steps to
replace it.
 Make sure all moving parts stops and the log
splitter is unplugged.
 Unscrew Oil Drain Bolt with Dipstick to remove
it.
 Turn the log splitter on the Support Leg side
over an 4 liters capacity container to drain the
hydraulic oil off.
 Turn the log splitter on the the motor side.
 Refill fresh hydraulic oil at the volume as per
the hydraulic oil capacity of a particular model
indicated in above specifications table.
 Clean the surface of Dipstick on the Oil Drain
Bolt and put it back into the oil tank while
keep the log splitter vertically.
 Make sure the level of the refilled oil is just
between 2 grooves around the Dipstick.
 Clean the Oil Drain Bolt before thread them
back. Make sure they are tightened to avoid
leakage before place 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.
Following hydraulic oils or equivalent are recommend for the log splitter’s
hydraulic transmission system:
• SHELL Tellus 22
• MOBIL DTE 11
