Lubrication
Wheels
Lubricate the wheels and bearings at least once a season with a light oil. Also if the
wheels are removed for any reason, lubricate the surface of the axle bolt and the
inner surface of the wheel with light oil.
Pivot Points
Lubricate the pivot points on the blade control, blade depth control lever, the blade
adjustment lever, and curb height adjustment lever with light oil at least once a
season.
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.
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 foot-
lbs. and 50 foot-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.
