WARNING
Never operate the
edger without the
spindle sheaves belt
guard in place.

Replacing the Drive Belt

IMPORTANT: 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 10.
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 10.
2. With your other hand, carefully reach under the
rear of the unit and remove the belt from around the
engine flywheel pulley.
3. Remove the spindle sheaves belt guard by removing
the two self-tapping screws which secure it to the
blade plate assembly. See Figure 10.
4. Carefully remove the belt from off of the pulleys,
again making sure to note the orientation of the belt.
Discard the belt.
Install the replacement belt (Part No. 754-04032B) in the
same configuration that the original belt was routed as
follows:

Off-Season Storage

Observe the following when preparing the edger for
long-term storage:
1. Clean and lubricate unit thoroughly as instructed on
page 11 of this manual.
2. Refer to the Engine Manual packed separately
with the edger for engine manufacturers's storage
instructions.
5. Working from the front of the edger, place the belt onto
the spindle sheaves, route it back onto the two idler
pulleys, and then place it onto the engine flywheel
pulley.
IMPORTANT: 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.
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.
IMPORTANT: 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.
WARNING: Never operate the edger
without the spindle sheaves belt guard
in place.
3. Coat the edger blade with chassis grease to prevent
rusting and corrosion.
4. Store the edger in a dry, clean area. Do not store next
to any corrosive materials, such as lawn fertilizer.
5. Coat the edger, especially any springs and bearings
with a light oil or silicone spray.
IMPORTANT: When storing any type of power equipment
in an poorly ventilated or metal storage shed, care should
be taken to rustproof the equipment.
