Cleaning Under The Belt Cover; Maintaining The Cutting Blade - Lawn-Boy Silver Series Operator's Manual

Cleaning under the Belt Cover

Under certain conditions, clippings can collect under the
belt drive cover and in the pulley groove. This can cause
the belt to slip, the self-propel drive to lose power, or the
the self-propel drive not to disengage.
Clean grass clippings and debris from under the belt cover
every 25 operating hours.
1. Remove the screw from the belt cover and slide the
belt cover to the rear, unhooking the tab on the front of
the cover from the deck opening (Fig. 21).

3. Reverse the procedure to install belt cover.

Maintaining the Cutting Blade

A straight, sharp blade provides maximum cutting
performance. Inspect and sharpen or replace the blade
every 50 operating hours (more frequently if the blade
edge dulls quickly in rough or in sandy conditions).
Warning
The blade is sharp; contacting the blade can result
in serious personal injury.
Wear gloves or wrap the sharp edges of the blade
with a rag.
1. Disconnect the wire from the spark plug (Fig. 8).
2. Tip the lawn mower onto its right side (air filter up)
(Fig. 18).

Inspecting the Blade
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Fig. 22A). Because sand and abrasive material can wear
away the metal that connects the flat and curved parts of
the blade, check the blade before using the lawn mower. If
you notice a slot or wear (Figs. 22B and 22C), replace the
blade; refer to Removing the Blade on page 16.

Note: For the best performance, install a new blade before
the cutting season begins. During the year, file down any
small nicks to maintain the cutting edge.
Danger
A worn or damaged blade can break, and a piece
of the blade could be thrown into the operator's
or bystander's area, resulting in serious personal
injury or death.
Inspect the blade periodically for wear or
damage.
Replace a worn or damaged blade.
