• Taking a Blue Shop towel or clean towel spread a small
amount of the 3-in-1 oil onto the towel and wipe it on/over
the Drum Shaft using this first towel to clean the shaft of
dust and grit. Use a second towel that is liberally anointed
with the 3-in-1 oil to lubricate the shaft, making sure to
wipe all around the shaft.
• Always use a clean towel when doing the first wipe
down on the Drum Shaft to avoid spreading the grime
from unit to unit.
• Lubricating the Acme Screw is similarly just as easy.
One difference is that you want as much of the screw
showing as possible. To achieve this, raise the batten to its
highest point of travel. Take another Blue Shop Towel as a
backing towel to prevent over spray and spray the Acme
Screw White Lithium lubricant onto the screw. Just one quick pass
usually suffices for lubricating this screw.
• When you finish with this step go ahead and replace
the cover making sure to fit the cover into the channels on
the aluminum backbone.
• Next and last step is blowing out the dust from the
electrical enclosure with the compressed air.
• Turn off power at the circuit breaker and unplugging the
communications plug from the top of the Vortek hoist you
will have made it safe to open up the enclosure.
• Using the same 7/32" hex key, remove the 2 Allen
head screws from the top of the Electrical enclosure and
swing down the cover.
• Hint: pushing the cover up at the curved hinges
while swinging the cover down will help in opening the
enclosure.
