Bearing Block
Lubricate the bearing block every 25 hours or at least once a season. Simply apply
oil at each end of the cover plate. See Figure 13.
Edger Blade Care
The edger blade is sharp. Wear leather work gloves to protect your hands
when working around the edger blade.
Periodically inspect the blade for cracks, especially if you strike a foreign object.
Replace when necessary. Follow the steps below for blade service.
1.
Disconnect spark plug boot from spark plug.
2.
Use two wrenches (one wrench to prevent the hex bolt head from spinning and
the other to remove the flange nut) to remove the edger blade. Refer to Figure 14.

SERVICE
3.
Remove and discard the edger blade but retain the flange nut and
flat washer.
4.
Install the flat washer, replacement edger blade, and flange nut removed
earlier. Use a torque wrench to tighten the flange nut to between 37 ft-lbs
and 50 ft-lbs.
NOTE: Make certain that the drive belt is seated correctly on the blade
spindle and that it is riding smoothly on the spindle sheaves (see Figure 16)
and is not pinched between them. Repeat the first three steps if the belt
is pinched.
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 15.
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 15.
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 15.
