STARTING THE ENGINE

The following procedure is for starting cold engines.
1. Ensure the FWD/REV pedal is in the neutral
position, the mow switch is off, the throttle
setting is in a mid position and the parking
brake is applied.
2. Turn the ignition switch to position No.2 and
hold until the glow plug light goes off (5-10
sec.)
3. Turn ignition key fully clockwise to the start
position and operate the starter motor until
the engine starts (This should only take a
few seconds)
4. When the engine starts, release the key
immediately and it will return to the RUN
position.
5. If the engine does not start, preheat the
glow plugs and try again.
NOTES:
• Warm engine - When the engine is warm
because of surrounding temperature or
recent operation, step No.2 of the cold
engine starting procedure may be omitted
(no need to preheat glow plugs).
• If the engine fails to start after two attempts
(with preheat if necessary), wait 20
seconds and try again.
• The starter motor should never be run
continuously for longer than 30 seconds or
it may fail.

brake is released before attempting to go
forward or reverse.

FWD/REV foot pedal to reach desired
ground speed.
• To stop - Gently return the FWD/REV foot
pedal to the neutral position.
• To hold the vehicle stationary on a slope it
may be necessary to apply a certain
amount of reverse traction.
NOTES:
