Cold temperature starting aids
WARNING
Explosion hazard!
DO NOT use ether starting fluid. Serious engine damage, explosion, death, or serious personal injury
could occur.
Failure to comply could result in death or serious injury.
This machine may be equipped with an engine grid heater. Turn the key switch to ON, and wait for the engine grid
heater indicator lamp to go out. The indicator light may come on again during cranking and shortly after the engine
starts for post heating. This allows for smooth running conditions during cold weather warm up. Contact your autho-
rized dealer for additional cold weather starting aids.
Machine warm up
To properly warm the machine in cold conditions:
1. Set engine speed to 1200 - 1400 RPM. Operate the
ground drive at no greater than speed 8.
2. Cycle the implement system functions by moving each
function the full cylinder stroke several times.
3. Repeat Step 2 for 10 min or until hydraulic oil temper-
ature is at least 10.0 °C (50.0 °F).
If the machine idles in cold temperatures, the engine will stay warm, but the hydraulic oil and brake oil will cool. The
oil and components can become cold, which will affect hydraulic function response time. If this should happen you
MUST go through the complete warm up procedure.
Make sure the track system is clean when you park the machine. In cold weather, park the machine on planks. This
will prevent the tracks from freezing to the ground.
NOTICE: If the track freezes to the ground, do not try to drive the machine. This will cause damage to the power train.
4 - OPERATING INSTRUCTIONS
NOTE: Warm oil to above 20.0 °C (68.0 °F) for opti-
mized performance.
4. Once the engine has started, run the engine at about
half throttle ( 1650 RPM) for a minimum of four min-
utes under no load. This will help stabilize the engine.
5. Operate the machine in a clear safe area. Check the
full operation of the machine.
