The hydrostatic gear is equipped with an expansion
tank (on the gear, g. 6.9 and 6.10) and factory-made
lled with corresponding hydraulic oil (refer to section
6.7). There is a cold/warm mark at the expansion tank.
In cold condition the oil level should not exceed the
cold mark (lower mark).
The cooling ns of the gear box are to be kept clean to
avoid overheating. Oil overheating might lead to gear
damages. Overheated oil has lost its greasing proper-
ties and has to be replaced. It can be recognised by its
black colour.
Change the CF-2116 D’s feed gear oil as follows:
1. Warm up (operate the machine) the hydrostatic feed
gear oil in order to drain the used oil components
tending to sedimentation as well.
2. Remove the water tank.
3. Place a suitable drip cup for approx. 0.65 litres hot
hydraulic oil beneath the hydrostatic feed gear.
DANGER!
Danger of injury due to hot hydraulic oil!
Wear appropriate gloves and use suitable
tools.
4. Loosen and remove the oil drain screw beneath the
hydrostatic feed gear (g. 6.10) and collect the oil.
5. Loosen and remove the ventilation/lling screw at
the hydrostatic feed gear (right beside the expansion
tank, g. 6.9).
ATTENTION!
Observe the safety instructions in chapter
3 and section 6.6.1. Handle the hydraulic
oil according to the supplier’s instructions.
Collect and discharge the used and leaked
hydraulic uid environment-friendly, according to
the local laws.
Provide information from the competent authority!

6. Clean the area of the oil drain screw and tighten the
screw together with a new seal ring.
7. Clean the bleeder screw’s position and brim-fully ll
in new hydraulic oil (section 6.7). If necessary, use a
funnel. Pay attention to utmost cleanliness. Neither
dirt nor water might penetrate the oil circuit.
Provide cleanliness when changing the
hydraulic oil!
Dirt is the greatest enemy of hydraulic
installations. Close all opened ller plugs as soon as
possible.
Provided that changing the hydraulic oil is effected in
time the hydrostatic feed gear has been designed for a
long lifetime. Polluted hydraulic oil will short the gear’s
lifetime considerably.
8. Hand-screw the bleeder screw together with a new
seal ring.
9. Fill the oil expansion tank with new hydraulic oil up to
2 cm below the cold mark. Close the lid.
10. Start the joint cutter’s motor, engage the feed gear
and drive the joint cutter for a short while with the
hydrostatic feed gear.
11. Disengage the feed gear and shut off the joint cut-
ter.
