Replacing and adjusting the

The centre belt runs between the engine shaft and the
gearbox.
Adjusting the centre belt
•
Unscrew the adjuster screws a few turns.
•
Adjust the belt by moving the gear forwards or
backwards.
MAINTENANCE
•
The belt should be stretched so that it can move
10mm in the centre. That corresponds to a pull of
approx. 3 kg. Use a fishing scale to check.
•
Tighten the adjustment screws properly.
•
Check the drive operation, as adjustment of the gear
affects the belt tension in the gearbox.
Replacing the centre belt
•
Remove the cutter.
•
Loosen the adjustment screws.
•
Replace the belt with a new one and tighten the
adjustment screws a little.
•
Adjust the centre belt. See instructions under the
heading "Adjusting the centre belt".
•
Assemble the blade.
Air filter
•
Remove the air filter cover and take out the filter.
•
Clean the filter by knocking the filter against a flat
surface. Never use solvent with petroleum, for
example, kerosene, or compressed air to clean the
filter.
•
An air filter that has been in use for a long time cannot
be cleaned completely. The filter must therefore be
replaced with a new one at regular intervals. A
damaged air filter must always be replaced.
•
When reassembling, make sure that the filter
completely seals against the filter holder.
Oil change
•
Empty the fuel tank.
•
Excellent S H, Comet S H, Pro 19 S H Close the fuel
tap.
•
Unscrew the oil filler cap.
•
Place a suitable vessel to collect the oil in.
•
Drain the oil by tipping the engine so that the oil runs
out through the filler pipe. Ask where you can dispose
of surplus engine oil at your local petrol station.
•

instructions in the section "Technical data".
