Cleaning the Cooling System
Before each use, check and clean the engine cooling
system. Remove any build-up of grass, dirt, or other
debris from the cylinder and cylinder head cooling fins,
air intake screen on flywheel end, and carburetor-governor
levers and linkage. This will help to ensure adequate
cooling and correct engine speed and reduce the
possibility of overheating and mechanical damage to the
engine.
Servicing the Brake
Before each use, check the brakes for proper operation.
Always set the parking brake when you stop the machine
or leave it unattended. If the parking brake does not hold
securely, an adjustment is required.
Checking the Brake
1. Park the machine on a level surface, disengage the
blade control (PTO), and set the parking brake.
2. Push the machine forward.
The rear wheels should lock. If the wheels turn and do
not lock, adjust the brake; refer to Adjusting the
Brake, page 28.
3. Release the brake and press upper control bar very
lightly, approximately 1/2 inch (13 mm).
The wheels should rotate freely. If not, adjust the
brake; refer to Adjusting the Brake, page 28.
Adjusting the Brake
The brake lever is on the upper control bar (Fig. 13). If the
parking brake does not hold securely or the control bar is
not parallel with the fixed bar, an adjustment is required.
