Whenever you install a new blade brake cable assembly
or replace the belt, adjust the blade brake cable.

4. Pull the cable to the remove slack, but do not
compress the spring. Tighten the cable clamp screw
to lock the adjustment in place.
WARNING
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 mower to an Authorized Service
Dealer for inspection and repair.

Blade Maintenance

Maintaining the 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.
3. Drain the gasoline from the fuel tank.
4. Tip the mower onto its left side (air cleaner
up)(Figure 34).

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 35A). 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
mower. If you notice a slot or wear (Figure 35B and C),
replace the blade; refer to Removing the Blade.
