Initial Operation - Scheppach HL760L Original Bedienungsanleitung

10. Initial operation

Before start-up, place the splitter on a stable, level and
flat workbench at a height of 72 - 85 cm. Fasten the
machine with 2 screws (M8 x X = thickness of the work-
bench) on the workbench. To do so, use the two holes
on the foot (16).
Make sure the machine is completely and expertly as-
sembled. Check before every use:
• the connection cables for any defective spots
(cracks, cuts etc.).
• the machine for any possible damage.
• the firm seat of all bolts.
• the hydraulic system for leakage.
• the oil level and
• the safety devices
10.1 Checking the oil level (Fig. 15)
The hydraulic unit is a closed system with oil tank, oil
pump and control valve. Check the oil level regularly
before every use. Too low an oil level can damage the
oil pump. The correct oil level is approx. 10 to 20 mm
below the oil tank surface. If the oil level is at the lower
notch, then the oil level is at a minimum. Should this be
the case, oil must be immediately added. The upper
notch indicates the maximum oil level. The machine
must be on level ground. Screw in the oil dipstick fully,
to measure the oil level.
10.2 Ventilation screw
Before operating your machine, the bleed screw
(7) should be loosened by some rotations until air
can go in and out of the oil tank smoothly. Failed to
loosen the bleed screw will keep the sealed air in
hydraulic system being compressed after being de-
compressed. Such continuous compression/decom-
pression will blow out the seals of the hydraulic system
and cause permanent damage to your machine. Be-
fore moving your machine, make sure the bleed
screw is tightened to avoid oil leaking from this point.
10.3 Splitting logs
Only split logs that have been sawn off straight. To do
this, proceed as follows:
1. Place the log plain onto the work table (9).
2. Your machine is equipped with Two-hands Control
System that requires to be operated by both hands
of the user – left hand controls the control lever (12)
while right hand controls the push button switch (6)
.
3. Simultaneously push button switch (6) to start the
splitting action.
The log splitter will freeze upon absence of either hand.
Never force your machine 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 should
be discarded to protect the log splitter.
10.4 Hoist limiting
It is reasonable to limit the hoist of the pressure plate
(10) for short splitting material. Thereto press the con-
trol lever (12) and the release button (6) and let the
pressure plate (10) move just in front of the splitting
material.
Release the release button now and mount the hoist
limiting ring (7a) to the housing and tighten it. After-
wards you can release the hydraulics lever.
The pressure plate will now be resting in the selected
position.
10.5 Wrongly placed log (fig. 11)
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 logs
on the upper part. This will break the blade or 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.
10.6 Jammed log (fig. 12 + 13)
Do not try to knock the jammed log off. Knocking about
will damage the machine or may launch the log and
cause accident.
1. Release both controls.
2. After the log pusher moves back and completely
stops at its starting position, insert a wedge wood
under the jammed log (see figure 13).
3. Start the log splitter to push the wedge wood under
the jammed one.
4. Repeat above procedure with sharper slope
wedge woods until the log is completely freed.
