Cold-Weather Starting
The ether cold starting aid may be used to assist
the engine starting in temperatures at or below 0°C
(32°F).
CAUTION: STARTING FLUID IS HIGHLY FLAMMABLE.
DO NOT USE NEAR FIRE, SPARKS, OR FLAMES. BE
SURE ALL OPERATORS READ THE CAUTIONARY
INFORMATION ON CONTAINERS.
NOTE: The vehicles electronic control system prevents
ether from being injected into the engine if the engine
coolant temperature is above 27˚ C (80˚ F).
After following steps 1 to 10 under “Engine Starting,”
proceed as follows:
1. If the engine does not start within 15 seconds
of cranking, depress the ether aid button (1) for
two seconds while the engine is cranking to inject
starting fluid and then release. If the engine does
not start after 15 more seconds, release the
ignition switch. Allow the starter motor to cool
down for two minutes, and repeat the procedure.
NOTE: The ether injection function only operates
while the start motor is cranking the engine.
IMPORTANT: Use only one starting fluid charge per
engine crank cycle of 30 seconds. Never hold the
button longer than 5 seconds, as damage to the
electric solenoid valve may result.
2. If, after the engine starts, it runs roughly while at
low idle with an outside ambient temperature
below 0° C (32° F), it is permissible to press the
cold start button and inject an additional amount
of starting fluid into the engine to aid in engine
warm-up.
NOTE: The cold start system injects a 4.8 cc metered
shot of starting fluid into the engine with each
depression of the switch.
ATTENTION: Use a maximum of three injections of
starting fluid into the engine for initial start-up and
engine warm-up. If the engine will not start or will not
smooth out, shut the tractor off and investigate the
cause. See “Engine Troubleshooting” in Section 4 of
this manual.
3. Once the engine has started, allow it to warm up
before putting it under load.
IMPORTANT: Pay attention to the warning light bar
and electronic monitor for any indication of a problem.
Stop the tractor immediately and investigate the
problem.
NOTE: If the engine fails to start after three attempts,
use a block heater or other means to warm the
engine.
