Operating Instructions
CAUTION
If the cutting blades strike a stationary ob ject while mowing, stop the mower imme diately, disconnect the spark plug wires, lift the deck, and inspect the deck and blades thoroughly for damage. Make sure that the blade timing has not been disturbed (the blades should be at 90 degrees to each other). Refer to REPLACING/REPAIRING the Blade Overload Shear Bolts in Mainte- nance Instructions if blades are out of time. Also, make sure the blade retaining nuts are torqued to 60 lb·ft (81 N·m).

STOPPING THE MACHINE
1.Pull the steering levers to the
2.Slow the engine to a fast idle; put the throttle in the 1/2 throttle position.
3.Disengage the blade clutch.
IMPORTANT: DO NOT disengage the blade clutch with high engine speed (above 1/2 throt tle) since the brake action on the blade drive will cause increased wear of the brake band.
WARNING
A brake stops the cutter blades and blower from freewheeling within five (5) seconds after disengaging the clutch. If the brake system malfunctions and the blades do not stop within five (5) seconds, the brake should be adjusted or repaired before op erating the mower. Contact your Walker dealer.
4.Slow the engine to idle, put throttle in IDLE po sition; and turn the ignition switch OFF.
WARNING
Remove the key from the ignition switch when leaving the mower unattended. This will prevent children and inexperienced operators from starting the engine.
5.Engage the parking brake. Also, engaging the parking brake is recommended when stopping or parking the machine in a confined space with little tolerance for movement.
IMPORTANT: The hydrostatic transmissions lock to prevent the mower from rolling freely with the engine stopped. However, if the mower is parked on a slope, it is necessary to ENGAGE the parking BRAKE to prevent the mower from creeping. This is due to a small amount of slip page in the hydrostatic transmissions, especially when transmission fluid is warm.
