Clean and Lubricate the Columns
Clean and properly lubricated columns are
essential to good machine performance and
safe operation. Extremely dirty conditions may
require that the columns be cleaned and
lubricated more often.
1 Raise the platform to the maximum height.
2 Visually inspect the inner and outer
channels of the columns for debris or
foreign material. If necessary, use a mild
cleaning solvent to clean the columns.
3 The bearing between chain wheel with the
shaft is lubricated with the calcium base
grease in raising.
4 Lubricate the place between chain wheel
with chain used grease gun.
5 Lubricate the lead rail with the calcium
base grease in raising.
This procedure will require
the use of additional access equipment. Do
not place ladders or scaffold on or against any
part of the machine. Performing this procedure
without the proper skills and tools may result in
death or serious injury. Dealer service is
strongly recommended.

Test the Up Limit Switch
Maintaining the limit switches is essential to
safe operation and good machine
performance.
Operating the machine with a faulty limit switch
could result in reduced machine performance
and a potentially unsafe operating condition.
Perform these procedures with the machine on
a firm, level surface that is free of obstructions.
1 Turn the key switch to ground control
2 While raising the platform from the ground
controls, push in the roller of the up limit
switch to activate the limit switch.
⊙ Result: The platform stops raising. The
machine is functioning properly.
¤ Result: The platform continues to raise.
