MAINTENANCE

• Using a low to medium pressure air stream, gently blow

any dirt and dust bunnies from the ventilation holes from both

sides of the drive inverter.

Note: Safety glasses should be worn

during this procedure.

• Re-install the cover and you are done with this

maintenance portion of the Vortek hoist.

• Last thing to check is the attachment connections for the

hoist to the structural steel.

These two 9/16" hex head bolts will need to be checked

for torque values of 17-20ft/lb.

Check both sets of clamps.

Check the nuts on the backbone

stiffeners for tightness.
