Prevent serious injury or death.

Do not attempt to remove Hydraulic Velocity Fuse (HVF) until maintenance
device securely supports lift and all hydraulic pressure has been relieved.

HVF is attached to elbow fitting in pressure port of cylinder. Do not use a
swivel fitting between HVF and cylinder. If HVF is installed improperly, it
will not lock up in event of a hydraulic line failure.


Pressurized fluids can penetrate the skin.

Hydraulic hoses can fail from age, damage and exposure.

Do not search for hydraulic leaks without body and face protection. A tiny,
almost invisible leak can penetrate the skin, thereby requiring immediate
medical attention.

Use wood or cardboard to detect hydraulic leaks, never your hands.


Spilled fluids and lubricants may be slippery and may also
present a fire hazard.

Clean up spilled fluids and lubricants.
