HOW TO
REPLACE THE DRIVE BELT
To replace the drive belt, the trimmer head
and shield must be removed as follows.
WARNING: Before you remove
the drive belt, disconnect the
wire from the spark plug.
1. Remove the two fasteners that hold the
rear of the shield to the trimmer housing
(See Figure 14).
2. Remove the four fasteners that hold the
front of the shield and trimmer head to
the trimmer housing.
3. Remove the “V” pulley from the idler
bracket.
4. Raise the front of the trimmer housing
and remove the drive belt. On some mod-
els, it is necessary to loosen the mount-
ing bolt for the drive pulley to remove the
drive belt (see Figure 15). Do not bend the
belt guides.
NOTE: Make sure you replace the drive
belt only with a replacement belt from
the factory.
5. To assemble the drive belt, reverse the
above steps. Make sure all fasteners are
tight. Make sure the mounting bolt for the
drive pulley is tight.
6. Check the routing of the drive belt. Make
sure the drive belt is inside of all belt
guides shown in Figure 15.
IMPORTANT: Test the drive system. Start
the engine and move the throttle control to
the FAST position. Engage and disengage
the trimmer head several times. When dis-
engaged, make sure the trimmer head com-
pletely stops when resting on the ground. If
the trimmer head continues to rotate, take
the machine to the nearest authorised
Service Dealer.
