DIMENSIONS OF THE SPLIT LOG
• Figure (fig. 8) shows the maximum dimensions of the split log. The diameter of the log is
decisive: a small log can be difficult to chop if it contains knots or unevenness, if the wood
has straight lines, it isn‘t difficult to split a log with a diameter larger than shown (fig. 8).
It‘s important not to try to split the log further if it doesn‘t do it at the first attempt. There is
a risk of damage to the pump due to overheating of the oil.
SPLITTING
• Secure the wheels with wedges to prevent movement during work.
• Plug the splitter into an AC outlet
• Check the switch and control lever for correct operation. Check the hydraulic system for oil leaks.
• Place the log lengthwise and straight on the splitting bed. The log must lie flat on the wedge
splitter and must be covered with guide plates. Make sure that the wedge and the pressure
plate catch the log at both ends vertically.
• Press the electromotor switch (fig. 9, 10 A). Wait a few seconds before the engine starts
and the pressure is generated in the hydraulic pump.
• Push / turn the hydraulic control lever with the other hand (fig. 10 B). (If the machine is
equipped with a non-accidental trigger guard, first press the lock to lock the lever.)
• The pressure plate presses the log onto the wedge, therefore splitting the log.
• If the log is split, release the control lever (fig. 10 B). The pressure plate returns to the starting
position.
• If you don‘t continue splitting immediately, release the engine switch.
• After work, don‘t forget to retighten the bleed screw (fig. 11).
• Never leave the machine unattended. If you leave the machine, even for a very short time,
unplug the power cord or take all possible steps to avoid unexpected start-up.
PROCEDURE FOR RELEASING A STUCK LOG
• Release both controls.
• After returning the pressure plates back to the starting position, place a wooden wedge
under the stuck log (fig. 12).
• Start the splitter and push on the wooden wedge that is inserted under the stuck log.
• Repeat with a wedge that has a larger angle until the jammed log is released.
MAINTENANCE AND STORAGE
CAUTION! A
To ensure proper functioning of the machine, it is necessary to have it checked and
adjusted by qualified personnel in an authorized service centre at least once a year.
Proper maintenance is essential for safe, economic and trouble-free operation of the machine.
