leather work gloves to protect your hands
when working around the edger blade.
_
WARNING: Disconnect the spark plug wire
and
ground
against
engine
before
performing the following
steps.
•
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 15.
•
With your other hand, carefully reach under the rear
of the unit and remove the belt from around the
engine flywheel pulley.
•
Remove the spindle sheaves belt guard by
removing the two self-tapping screws which secure
it to the blade plate assembly. See Figure 9.
•
Use two wrenches (one wrench to prevent the hex
bolt head from spinning and the other to remove the
hex lock nut and bell washer) to remove the edger
blade. Refer to Figure 10.
•
Remove and discard the edger blade but retain the
bell washer and hex lock nut.
•
Install the replacement edger blade, the bell
washer (cupped side facing inward) and the hex
lock nut removed earlier.
IMPORTANT:Use a torque wrench to tighten the hex
lock nut to between 37 foot-lbs, and 50 foot-lbs.
Reinstall the spindle belt guard with the self tapping
screws removed earlier.
Carefully place the drive belt back onto the engine
flywheel pulley, and retighten the flange lock nut on
the top of the frame.
IMPORTANT:Make certain that the drive belt is seated
correctly on the blade spindle 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.
