PIPE THREAD SEALANT
Loctite PST #567 pipe thread sealant or equivalent is recommended. Do not use
Teflon tape. Tape fragments can cause malfunctioning of the hydraulic system.
VELOCITY FUSE REPLACEMENT
DANGER !
Do not attempt to remove the velocity fuse until the lift is securely
supported with the lift blocking devices and all hydraulic pressure has
been removed from the lifting cylinders and hydraulic hoses. Failure to
follow these instructions could result in personal injury or death!
Never attempt to take a velocity fuse apart and repair it. These are precision devices
that are factory assembled under exacting conditions. Velocity fuses should always be
replaced.
1. The arrow on the exterior surface of the velocity fuse shows the direction of the
restriction to the oil flow. The arrow should always point away from the cylinder.
2. Do not use Teflon tape on the threaded connections of a velocity fuse. Tape
fragments can cause malfunctioning of the fuse.
3. Check all fitting connections for hydraulic leaks and tighten as necessary.
WARNING !
To avoid serious injury or death, GUARDS, INTERLOCKS, and SAFETY
DEVICES must be restored to correct operation when installing parts or
making repairs.
