This log splitter is equipped with '2HW 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 freeze 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 splltter for more than 5
seconds by keeping pressure on it to split

sxcesslvely hard wood.
Fig. 5
After this time interval, the oil under pressure
will be overheatedand the machine could be
damaged. For such extremely hard log, rotate
it by 90' to see whether it can be split in a
differentdirection. In any case, if you are not
able to split the log. this means that its
hardness exceeds the capacityof the machine
and thus that lcg should be discarded to
pmtectthe logsplitter.
NOTE: During operation, the metal part
connected to the motor remains coldor in any
case reaches a temperatureonly slightly
higherthan
the ambient temperature. After
several hours of use with particularly difficult
wood, the pump may, become very hot. This is
not a dangeroussituation for the machine,
which
returns to fullfunctioning capacity after
beingcooled. On the other hand, it is very
important not to cause overheating of the oil,
and thus the pump, by forcing the machinein
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 wilt
not twist, rock or slip while being split. Da
not force the bladeby splitting the log on
the upper part. Thb will break the blade or
damage the machine.
Break log in the direction of its grown grain. Do
not place log across the log splitter for splitting.
It may be dangerous and may seriously
damage the machine.
Do not atfempt to split 2 pieces of logs at the
same time. One of themmay fly up and hit
you.
