Adjusting the Blade Brake
Cable
Service Interval: Every 100 hours
Whenever you install a new blade brake cable assembly
or replace the belt, adjust the blade brake cable.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Figure 12).
3. Loosen the cable clamp screw until the brake cable
conduit slides (Figure 31).

4. Pull the cable to the remove slack, but do not put
tension on the spring. Tighten the cable clamp screw
to lock the adjustment in place.
Do not overtighten the blade brake cable.
Overtightening the blade brake cable could
cause the blade brake to come off of the brake
drum. If the brake does not contact the drum,
the blade will not stop rotating when you release
the control bar. A rotating blade could cause
serious personal injury.
• Each time you adjust the brake cable, ensure
that the brake stops the blade in 3 seconds
or less.
• If the blade does not stop rotating in 3
seconds or less, bring the lawn mower to
an Authorized Service Dealer for inspection
and repair.

Blade Maintenance
Maintaining the Cutting Blade
Always mow with a sharp blade. A sharp blade cuts
cleanly and without tearing or shredding the grass blades.
1. Stop the engine and wait for all moving parts to stop.
2. Disconnect the wire from the spark plug (Figure 12).
3. Drain the gasoline from the fuel tank; refer to
Emptying the Fuel Tank and Cleaning the Fuel Filter.
4. Tip the lawn mower onto its right side (Figure 32).

Inspecting the Blade
Service Interval: Before each use or daily
Carefully examine the blade for sharpness and wear,
especially where the flat and the curved parts meet
(Figure 33A). 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 (Figure 33B
and Figure 33C), replace the blade; refer to Removing
the Blade.
