OPERATION

WARNING! Before operating the log splitter, the bleed screw (13) Fig. 3, 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 while the log splitter is
!
under operations.
When finishing work, or before moving the log splitter, make sure the bleed screw is
tightened to avoid oil leaking from this point.
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
OUT THE SEALS OF THE HYDRAULIC SYSTEM AND CAUSE PERMANENT
DAMAGE TO THE LOG SPLITTER.
DO NOT ADJUST THE MAX PRESSURE LIMITING SCREW (14) IN FIG. 4!
Max pressure was set before the log splitter ex work and the max pressure
limiting screw is tightened to ensure the log splitter works under pressure no
more than 5 tons. The setting was done by qualified mechanic with
professional instruments.
Figure 3
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.
The max pressure limiting screw is protected by a plastic cap (15) as shown in
Fig. 4, and never to loose and adjust it.
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 as shown in Fig. 5. The log splitter will stop
working upon absence of either hand. Only after both hands release the controls,
the log pusher starts to return backward to the starting position.
Never force the log splitter for more than 5 seconds by keeping pressure on it
to split excessively hard wood.
Figure 4
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.
NOTE: During operation, the metal part connected to the motor remains cold or may
reach a temperature only slightly higher than the ambient temperature. After several
hours of use with particularly difficult wood, the pump may become very hot. This is
Figure 5
not a dangerous situation for the machine, which returns to full functioning capacity
after being cooled. On the other hand, it is very important not to cause overheating
of the oil, and thus the pump, by forcing the machine in an attempt to split logs that
exceed the capacity of the machine.
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.
