11.4.5 Checking the belt tension
Warning:
Only check the belt tension with the engine off. Remove the spark plug cap.
• At the inner side of protective cover over the drive contains a
black, round cap. Pull it away from the hole.
• Through the opening you can clearly see the V-belt. When
pressing the belt down with one's thumb (applied force ap-
proximately 7.5 kg), it should not move more than 1 cm. In that case, the tension is sufficient.
• Place back the rubber cap after checking the belt tension.
• If the belt tension proves to be too loose or too tight, it must be adjusted. A loose drive belt
will bang against the protective cover.
• Because a new belt will expand somewhat during the first period of operation, it is recom
-
mended to adjust the tension after 10 hours of operation (see § 11.5.5 Adjusting belt tension).
