LOG SPLITTER OPERATION
MAKE SURE THAT THE SCREWS ARE
TIGHTENED UP PROPERLY BEFORE
OPERATING THE LOG SPLITTER!
THE BLEED SCREW SHOULD BE
LOOSENED BY SOME ROTATIONS
BEFORE OPERATING THE MACHINE!
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 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.
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.
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.
