Operating Instructions
39
WARNING
A brake stops the cutter blades and GHS
blower from freewheeling within five (5)
seconds after disengaging the clutch. If
the brake sys tem malfunctions and the
blades do not stop within five (5) seconds,
the brake should be repaired or replaced
before further operation of the mower.
Contact your Walker dealer for service.
4. Slow the engine to idle, put throttle in
IDLE
position; 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 op-
erators from starting the engine.
5. Engage the parking brake by moving the lever
forward.
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 slippage in the hydrostatic trans-
missions, especially when transmission fluid is
warm. Also, engaging the parking brake is
recommended when stopping or parking the
machine in a confined space with little toler-
ance for movement.
CAUTION
An operator presence switch (seat switch)
will cause the engine to stop if the parking
brake is in the DISENGAGED position and
the operator is not in the seat. The function
of this switch should be checked by the op-
erator raising off the seat with the parking
brake lever in the DISENGAGED position
(tractor not moving and blade clutch disen-
gaged); the engine should stop. NOTE: Al-
low 1/2 second “off the seat” for the time
delay function. If the safety sys tem is not
working, it should be repaired or replaced
before operating the mower. DO NOT dis-
connect the safety switches; they are for
the operator’s protection.
WARNING
In case the transmission drive belt breaks
during operation, and if the machine is on
a slope, the machine will freewheel down
the slope. To maintain control, immediate-
ly (1) Release the steering levers and si-
multaneously (2) Move the FSC to the NEU-
TRAL-PARK position. When the machine
is stopped or moving slowly, engage the
parking brake.
NOTE:
The emergency stop procedure is
exactly the same procedure as used to nor-
mally stop and park the machine.
ADJUSTING CUTTING HEIGHT
WARNING
The engine must be stopped before adjust-
ing cutting height. Disengage the blade
clutch (PTO), engage the parking brake,
stop the engine, and remove the ignition
key. Wait for all move ment to stop before
getting off the seat.
