®
Mowers Dealer.
The safety interlock system should always function per
steps 4 and 5. If it does not function properly, it should be
corrected immediately. Do not operate machine without
properly functioning seat safety switch
Engine starting
The mower’s safety start interlock system is also designed to
protect the operator and others from accidental injury due to
unintentional engine starting. The engine starting motor will not
engage until:
1.
Steering control levers are in the park brake position.
2.
Deck clutch switch is in the down (OFF) position.
The safety interlock system must not be disconnected or
bypassed. Doing so could cause the machine to operate
unexpectedly resulting in personal injury.
NOTE:
The operator’s seat is equipped with a separate
safety switch. If for any reason the operator should become
unseated when the steering control levers are not in the park
brake position (park brake switches are disengaged) or the deck
clutch switch is engaged the engine will stop.
The following steps are the correct procedures for starting the
engine. If difficulty is encountered, contact the BigDog
®
Mowers Dealer in your area.
1.
Before starting mower each day, perform daily pre-
operation checking. (See
Safety Start Interlock System

Make sure the steering control levers are in the park
brake position and deck clutch switch is disengaged.
Only start the engine from the operator’s position.

5.
Insert key in ignition switch and rotate full clockwise to
engage starting motor. Release key when engine starts.
IMPORTANT:
The engine starter should not be operated
for periods longer than 30 seconds at a time. An interval
of at least two minutes should be allowed between such
cranking periods to protect the starter from overheating
and burn-out.
6.
Perform test to make sure safety start interlock system is
operating properly. Refer to
Safety Start Interlock System
section.
7.
As soon as engine begins to run, check to make certain
the oil warning light is off. If not, stop engine
immediately and check for the cause.
NOTE:
Some mowers have an engine malfunction light
and/or an alternator warning light in addition to the oil
warning light. Check to make certain these lights are off
as soon as the engine begins to run. If not, stop engine
immediately and check for the cause.
8.
Allow the engine to idle a few minutes before advancing
the throttle and/or engaging the deck clutch.
