• 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
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
2.5mm2 to 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.
Keep you hands away from splits and cracks which open in the log; They may close
suddenly and crush or amputate your hands.
Do not remove jammed logs with you hands.
• DON'T FORCE TOOL
It will do a better and safer job at its design rate. Never try to split logs larger than those indicated
in the specifications table. This could be dangerous and may damage the machine.
Don't use log splitter for a purpose for which it was not intended.
• NEVER LEAVE TOOL RUNNING UNATTENDED
Don't leave tool until it has come to a complete stop.

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 PERMANT DAMAGE TO THE LOG SPLITTER.
DO NOT ADJUST THE MAX PRESSURE LIMITING SCREW !.
Max pressure was set before the log splitter ex work and the max pressure limiting screw is sealed
with glue 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 .

Before operating the log splitter, the Bleed Screw 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 during 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.

LOG SPLITTER OPERATION
EN
EN
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 dam-
age 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
• 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.
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 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 90o 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.
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
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.
