Adjusting the Blade Brake

Cable

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.
3. Loosen the cable clamp screw until the brake
cable conduit slides (Figure 29).

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 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 30).
