Cutting unit
Checking the drive belt
1. Allow the engine to cool.
2. Remove the spark plug cable.
3. Remove the belt guard (see illustration) on the left
side of the machine.
4. Check that the belt is running in the proper track;
the pulleys should guide the belt in a straight line.
5. Check that the belt and pulleys are not oily. If they
are, fi rst try to clean them with spirits. If they are
heavily coated, take the machine to an authorized
service workshop to fi x the oil leakage and replace
the belt.
6. Check the belt for cracks, heat damage or worn
edges. If these symptoms appear, replace the drive
belt; see “Replacing the drive belt”.
7. Check that guide and tensioning equipment
for the belt is not loose and is properly set; see
“Replacing the drive belt”.
8. Refi t the belt guard.
Replacing the drive belt
Replace the drive belt as follows:
1. Allow the engine to cool.
2. Remove the spark plug cable.
3. Remove the belt guard.
4. Remove the old belt.
5. Check for wear on the pulleys and replace as
necessary.
6. Check the pulley setting against the rotor pulley
and adjust as necessary. The belt should run in
the track.
7. Check the tensioning pulley. The bearings should
rotate freely and evenly. The rocking lever on the
tensioning pulley should be free with a lateral play
of not more than 6.5 mm (0.25") (see illustration).
Replace as necessary.
8. Fit a new belt by fi rst pulling it over the lower
pulley and then the engine pulley. Check that the
tensioning pulley and belt guides end up outside
the belt loop.
