10.7.1 Ignition (Key) Switch
By using the key, the ignition switch (5, Fig. 10.17)
may be turned clockwise from the OFF position to
the RUN, THERMO START (Perkins only) AND
START positions. The THERMO START (Perkins
only) AND START positions are spring-loaded to
return to the RUN position and must be manually
held in place for cold starting or normal starting.
When starting in cold weather, momentarily hold
the key in the THERMO START position (Perkins
only) before turning it fully to the START position.
• In the OFF position, the entire electrical
system is shut down (there is power to
ignition switch and to starter solenoid only).
• In the RUN position, all controls and indica-
tors are operable.
• In the RUN position with the Park Lock
engaged, oil pressure and alternator lights
must be ON. Press Bulb Check switch;
remaining warning lights must turn ON.
• Perkins Only - In the THERMO START
position, the ignition switch energizes the
Thermo Start plug (Fig. 10.12) which ignites
a fuel/air mixture in the intake manifold to
facilitate cold weather starting. Refer to
paragraph 10.5.5 for Thermo Start plug
removal and installation instructions.
• In the START position (with the parking lock
engaged and the travel select lever in
neutral) the starter pinion engages the
flywheel to start the engine.
If the key binds in the lock, check for a sticky,
painted or bent key. If key is sticky, clean key. If
key is painted, remove paint. If key is bent,
straighten key. If the key is straight and usable,
sprinkle some powdered graphite on the sides of
the key and insert key in lock several times to
distribute the graphite. If the lock should fail to
accept key or fail to turn due to freezing tempera-
tures, warm the key switch using a hair dryer or
use a liquid lock deicer to lower the freezing point
and evaporate the moisture within the lock.
IMPORTANT: Use only graphite or a liquid lock
deicer within the lock. Severe lock malfunctions
may require the services of a locksmith.
