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, first try to clean them with spirits. If they are heavily coated, take the machine to an authorized service workshop to fix 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.Refit 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 first 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.

9.Adjust the belt guides as necessary and refit the belt guard.
