ley and the crank pulley with a finger, to check the fan
belt tension.
Pressing force : Approximately 22.1 lbs. (10 kg)
Correct slack : 0.4 to 0.6 in. (10 to 15 mm)
3) Adjust the tension if necessary.

Things to prepare
• Wooden bar (e.g., the handle of a hammer)
1) Open the cover (1) under the operator's seat (2).
2) Tilt the operator's seat (2) forward, remove the mount-
ing bolts (3) and remove the cover (4).
3) Loosen the generator mounting bolt (5).
4) Insert a wooden bar between the generator (6) and the
cylinder block, and move the generator (6) to adjust the
tension of the fan belt (7) so that the belt will be de-
pressed approximately 0.4 to 0.6 in. (10 to 15 mm) with
a pressing force of 22.1 lbs. (10 kgf).
• Stop the engine, take out the starter switch key,
and attach the "SERVICING IN PROGRESS" tag
to a control lever.
