Service Interval: Every 100 hours
Whenever you install a new blade brake cable assembly or
replace the belt, adjust the blade brake cable.

2. Disconnect the wire from the spark plug.
3. Loosen the cable clamp screw until the brake cable
conduit slides (Figure 35).

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 machine 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 machine to the side, with the dipstick down
(Figure 36).

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 37A).
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 machine. If you notice a slot
or wear (Figure 37B and C), replace the blade; refer to
Removing the Blade (page 25).
