Warm-up
On AL 300 Series machines, the parking
brake must be left engaged for three min-
utes after starting a cold engine, or damage to the hydraulic pump
may result.
Note: The operator may leave the operator’s seat while warming a cold engine.
Apply the parking brake before leaving the operator’s position; the engine will
stop if the operator’s seat is not occupied and the parking brake is not applied.
Important: Do not run a cold engine under load; engine life may be shortened.
1. Run the engine at a low, consistent speed for a few minutes before operating
any controls. Check for any unusual sounds and vibrations.
2. Check if any indicators illuminate (see “Warning Indicators” on page 58).
Important: If unusual sounds or vibrations occur, or if any warning indicators
illuminate, stop the engine immediately and determine the cause. Repair or
replace parts as necessary before re-starting the engine.
3. Exhaust gas color should be light blue or colorless.
Note: Black exhaust indicates possible engine malfunction. See “Engine Trouble-
shooting” on page 153.
Important: Do not run a malfunctioning engine under load; engine life may be
shortened.
4. During warm-up, test the following for proper function:
• Brake/Inch pedal. See “Controls and Switches” on page 52. See “Travel”
on page 74.
• Steering. See “Controls and Switches” on page 52.
• Accelerator pedal. See “Controls and Switches” on page 52.
• Multi-purpose joystick. See “Multi-purpose Joystick” on page 78.
