CHAPTER 5:
ADJUSTMENT
5.1. START
5.2. BLEEDING
• Make sure all pins and bolts to insure proper mounting
• Make sure the electrical system feeding voltage is equal to that specied in the nameplate on the
motor
• Make sure the electric connections are in compliant with the electrical diagram.
• Make sure no leakage or blow-up in hydraulic line
• Make sure the working area is free from people and objects
• Grease sliding seats of blocks placed under platforms and on bases
• Pour oil in the tank (about 5 liters more then one time)
• Verify that the control unit is powered
• Verify that the motor direction of rotation is that shown on the label by pushing UP button. If
motor gets hot or sounds peculiar, stop immediately and recheck the electric connections
• Turn on the two leveling valves, raising the lift slowly by pressing UP button until cylinders bottom
out and the lift stops. DO NOT continue pressing button after lift reaches full height. Damage to
motor can occur if continued.
• Cylinders may jump upon initial start up which is normal due to trapped air inside the hydraulic
lines. In case that the lift cannot be raised upon initial start up due to trapped air inside the pump:
unloose the maximum pressure valve, in-push the UP button and retighten the valve after trapped
air has escaped, then raise the lift at full height.
• Lower the lift completely.
• Repeat raise and lower the lift completely at least 3 times to equalize the oil pressure in each
cylinder.
• Trun off two leveling valves, raising lift to check if two platforms are in the same level. If not, turn
on the leveling valve on the platform which raise slowly, then rising two platforms to the same
level.
• Turn off two leveling valves, pressing LOWERI to lower the lift, if two platforms not in the same
level, turn on the leveling valve on the platform which lower slowly, then lowering two plat forms
to the same level.
• Turn off the leveling valves, press UP to check the platforms are in the same level. If not, pls repeat
the above last two steps.
