10. Maintenance and repair

Switch off the motor and pull the power supply plug
before undertaking any converting, maintenance, or
cleaning work.
m Always pull power plug!!
Skilled craftsmen can execute smaller repairs on the
machine themselves.
Repair and maintenance work on the electrical
system may only be carried out by an electrician.
All protection and safety devices must be replaced
immediately after completing repair and mainte-
nance procedures.
We recommend:
• Thoroughly clean the machine after every use.
• Splitting knife
The splitting knife is a wearing part that should be
reground or replaced by a new one, if necessary.
• Two-hand control
The combined supporting and control unit must be
kept easy-going. Occasionally grease with a few
drops of oil.
• Moving parts
Keep splitting knife guides clean from dirt, wood
chips, bark etc.
Grease sliding rails with oil spray or grease.
• Checking the hydraulic oil level
Check hydraulic connections and bolts for tightness
and wear. Retighten the bolts if necessary.
Checking the oil level
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.
Note: The level of oil must be checked when the riv-
ing knife is pulled back. The measuring stick for the
oil is located on the base in the ventil cap (K) (Fig.
7) and has two notches. 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 up-
per notch indicates the maximum oil level.
The splitting column must be retracted before the
check, the machine must be level.
When must the oil be changed?
First oil change after 50 operating hours, then every
500 operating hours.

Changing the oil (Fig. 6, 7)
• Completely retract the splitting column.
• Put a bin of at least 10 litres capacity underneath
the log splitter
• Release the venting cap (K).
• Open the drain plug (L), allow the oil to run out.
• Close the drain plug (L) again and tighten it prop-
erly.
• Fill bit by bit 9 litres of new oil in with the help of
a clean funnel and check in between times the oil
level.
• Refit the venting cap (K) after the correct oil level
has been reached.
Dispose of the used oil in a correct manner at a
public collection facility. It is prohibited to drop
old oil on the ground or to mix it with waste.
We recommend the following hydraulic oils:
Aral Vitam gf 22
BP Energol HLP-HM 22
Mobil DTE 11
Shell Tellus 22
or oils of same quality.
Do not use any other types of oil as they would
influence the function of the hydraulic cylinder.
Splitting spar
Before use, the spar of the splitter must be slightly
greased. Repeat this procedure every five operating
hours. Slightly apply grease of oil spray. The spar
may never run dry.
Hydraulic system
The hydraulic unit is a closed system with oil tank, oil
pump and control valve.
The system is complete when the machine is deliv-
ered, and may not be changed or manipulated.
Regularly check the oil level.
Too low an oil level damages the oil pump.
Regularly check the hydraulic connections and bolts
for tightness. Retighten if necessary.
Before undertaking any maintenance or checking
work, the working area must be cleaned. Keep the
necessary tools within the reach of your hand.
The intervals mentioned herein are based on normal
conditions of use. An excessive use of the machine
shortens the intervals accordingly.
Clean the panels, screens and control levers with a
soft cloth. The cloth should be dry or slightly humid
with a neutral cleaning agent. Do not use any sol-
vents like alcohol or benzene as they could damage
the surfaces.
Store oil and grease outside the reach of unauthor-
ized personnel. Strictly follow the instructions on the
bins. Avoid direct contact with the skin. Rinse well
after use.
