BELT REPLACEMENT
NOTE: To aid in reassembly, note the orientation of the drive belt on
the two idler pulleys and the engine flywheel pulley prior to performing
the following steps. Refer to Figure 17.
The edger drive belt is subject to wear and should be replaced if any
signs of cracking, shredding or rotting are present. To replace the belt,
proceed as follows:
1. Working in front of the edger, loosen the flange lock nut on top of
frame, allowing the idler pulley assembly to pivot slightly out from
the frame. See Figure 17.

2. With your other hand, carefully reach under the rear of the edger
and remove the belt from around the engine flywheel pulley. See
Figure 17.

4. Carefully remove the belt from off of the pulleys, again making
sure to note the orientation of the belt. Discard the belt. See
Figure 18.
5. Working from the front of the edger, place the belt onto the spindle
sheaves, route it back onto the top and bottom idler pulleys, and
then place it onto the engine flywheel pulley.
NOTE: Make certain that the "V" side of the belt is seated into the top
pulley and the flat side of the belt is seated into the bottom pulley. See
Figure 18.
6. Reinstall the spindle sheaves belt guard with the self tapping
screws removed earlier.
7. Make certain that the drive belt is on the engine flywheel pulley
and idler pulleys, and retighten the flange lock nut on the top of
the frame.
NOTE: Make certain that the drive belt is seated correctly and that it
is riding smoothly on the spindle sheaves and is not pinched between
them. Repeat the first three steps if the belt is pinched.
Never operate the edger without the spindle sheaves belt guard in
place.
