DANGER !
Do not attempt to remove the velocity fuse until the lift is
securely supported with the maintenance locking 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!
VELOCITY FUSE REPLACEMENT
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. Tape fragments can
cause malfunctioning of the fuse. See Pipe Thread Sealant above.
3.
Check all fitting connections for hydraulic leaks and tighten as necessary.
