Table 4. Proc_Cal_002: Hydraulic Valve Calibration Warm Up and Air Bleed (Continued)
NOTE: Optional for initial manufacture.
Information: To ensure that the oil temperature is optimal, warm up the hydraulic fluid until it is within a range of
50 to 65°C (122 to 149°F).
Action:
• Ignition: ON
• Engine: High Idle
• Transmission: Neutral
• Park Brake: ON
Step 1: (Optional hoist valve air bleed): Activate Lift Control from neutral to full lift and back to neutral at a
rate of one or two times per second. Repeat until the lift function is operating smoothly and there is no
mast movement upon engine start.
Step 2: (Optional cylinder air bleed): Cycle function completely two or three times; repeat if necessary.
NOTE: Optional for initial manufacture.
Step 3: (Required warm up for service): Activate tilt at relief pressure until the hydraulic fluid temperature
is within the optimum range 50 to 65°C (12 to 149°F).
Step 4: Proceed to calibrate desired electro-hydraulic functions.
Information: You do not need to START or turn OFF the vehicle if you are performing other procedures.
