Important!
Before operating the log splitter, the Bleed Screw (15) should
be loosened by some rotations until air can go in and out of
the oil tank smoothly. Air flow through 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.
Warning!
Failure 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 lout the seals of the hydraulic system and cause
permanent damage to the log splitter.
17. Max Pressure Limiting Screw.
Warning!
DO NOT ADJUST THE MAX PRESSURE LIMITING SCREW!
Max pressure has been set at the time of manufacture to limit
compression to either a 5 ton or 4 ton settings. The setting
was done by qualified mechanics with professional instruments.
Unauthorised resetting will cause the hydraulic pump
fail to output enough splitting pressure or RESULT IN SERIOUS
INJURY AS WELL AS DAMAGE TO THE MACHINE.

Pusher Adjustment
The pusher has three holes for adjustment. To extend or retract
the pusher, remove the slider pin and align the required hole on the
pusher with the hole in the piston rod and replace the slider pin.
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.
A 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 pushing the Hydraulic Control Lever forward.
Warning!
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 90° 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.
Warning!
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.
Important!
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 two 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.
Important!
Do not try to knock the jammed log off. Knocking about
will damage the machine or may launch the log and
cause accident.
Changing the 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 litres
capacity container to drain the hydraulic oil off, diagram ‘A’
• for 5 Ton models, diagram ‘C’ for 4 Ton models, below.
• Turn the log splitter on the the motor side, diagram ‘B’ for 5
Ton models, diagram ‘D’ for 4 Ton models, below.
• 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 the two
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.
Important!
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:
Any hydraulic fluid sold at farm, hardware or automotive supply
stores. For example
SHELL Tellus 22.
BP Hyspin AWS 22.
Sharpening the Wedge
After using the log splitters 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.
