COLD WEATHER WARM UP PROCEDURE
When air temperatures are cold, it may be necessary to warm up the unit’s hydraulic oil before you start
your daily route operation. Follow these steps:
1. Start the truck and let the engine idle.
2. APPLY the parking brake and make sure it holds.
3. Engage the hydraulic pump for approximately five minutes.
Moving parts on the unit are dangerous. Serious injury or death may occur if
a person is struck by the equipment. Clear all people of the area before you operate the unit
4. MAKE SURE the area around the unit is clear of all people before you operate the controls.
5. Operate the lift and body hydraulic functions through 10 (ten) cycles while the engine idles. This
warms the hydraulic oil.
6. Check for fluid leaks again. Repair if necessary.
7. The unit is now ready to go on route.
