ELECTRICAL REQUIREMENTS
Connect the main leads to a standard 230V+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 0.03A.
SET UP AND PREPARATION FOR OPERATION
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.
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.
Max Pressure Limiting Screw
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 .

LOG SPLITTER OPERATION
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 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
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.

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.
