COLD START PROCEDURES FOR +32° TO -26°F (0° TO -32°C)
AND -26° TO -40°F (-32° TO -40°C) -- CONTINUED
Warm Up Procedure: -26° to -40°F (-32° to -40°C)
Slowly operate the steering to full lock each way for 1 minute.
Then select the hose reel (without hand tool attached) for 1 minute.
With the service brake depressed operate parking brake 5 seconds off, 5 seconds on for 1 minute. The handbrake should
be ON before proceeding on to step 4.
Then operate each of the loader and backhoe services (up and down, crowd and dump, etc. as relevant) in turn blowing
relief for 10 seconds only each time.
Repeat steps 1 through 4 for at least 10 minutes.
When the hydraulic oil temperature reaches 32°F (0°C) (when oil cold light goes off) you can begin to operate the suspen-
sion from transport mode (down) to travel mode (up) repeat for 5 minutes, making sure the suspension is locked in mode
(light is solid on selected mode) before proceeding to the next step.
Test and ensure correct operation of the brake system when moving off. Failure to do so may result
in injury or death to personnel.

PARKING MACHINE IN EXTREME COLD WEATHER +32° TO -25°F (0° TO -31°C)
Refuel the machine immediately after operation. This will reduce condensation inside the fuel tank.
Park the machine in a sheltered area, if possible. Cover to protect engine, accessories, and controls from snow and ice.
Park the machine on high, dry ground, or on planks or brush. This will prevent the tires from freezing to the ground.
Block up the front loader bucket, to prevent it freezing to the ground.
Clean wet snow or mud from the tires and the hydraulic cylinders before it freezes.
In extremely cold weather, notify Field Maintenance to remove the batteries and store them in a moderately warm area.
Have the batteries reinstalled just prior to starting the engine.
