a. REMOVAL

WARNING

Use extreme caution when handling heavy parts. Lifting device is required when

parts weight over 50 lb (23 kg) for a single person lift, over 100 lb (45 kg) for a two

person lift, and over 150 lb (63 kg) for a three or more person lift. Keep clear of heavy

parts supported only by lifting device. Failure to follow this warning may cause

serious injury or death to personnel.

DO NOT attempt to replace both lift cylinders at the same time unless dolly halves are

attached to each other or top beam is supported by a suitable lifting device. If top

beam is not supported, it will fall to the ground. Failure to follow this warning will

cause serious injury or death to personnel.
