MAINTENANCE-FREE MOTOR
Both the 120 Volt and the 24-Volt VSD-7500 lifts use a high-
torque motor. This is an extremely efficient and durable
internally geared motor that has the brake built into it. Its sealed
oil-filled gear box keeps the internal gears permanently
lubricated, making the motor virtually maintenance-free.
VSD PRE-INSTALLATION
CHECK LIST
Prior to installing your lift please follow this check list to
confirm proper operation
1. Raise the lift up to confirm operation of upper limit
switch. Approach the upper-limit cautiously by pressing
the UP button in short bursts as you near the top of the lift
travel. A properly working limit switch will stop the lift
before the ball screw reaches its limit of travel. If the limit
switch does not stop the lift and the ball-nut reaches the
end of the ball-screw you will be able to see the drive unit
twisting slightly, indicating that the motor is trying to run.
Also, you probably would have heard the ball nut hitting
the metal stop at the end of the screw. The brake will still
click when stopped at the limits.
2. Lower the lift down to confirm operation of lower limit
switch. Again, as you approach the bottom of the lift travel
press the DOWN button in short bursts. The lift should
stop with a small amount of slack in the lifting cable after
the cradle contacts the lift frame. If the limit switch does
not stop the lift and the ball-nut reaches the end of the
ball-screw you will be able to see the drive unit twisting
slightly indicating that the motor is trying to run. Also, you
probably would have heard the ball nut hitting the metal
stop at the end of the screw.
If either limit switch does not stop the lift correctly,
contact your FLOE dealer and do not use the lift until
the problem is corrected.
3. Listen for unusual noises during lift operation.
Squeaking may indicate that the lift may not have
been greased. The ball screw MUST be greased
before using the lift. Please see owners’ manual for
details.
4. If you have a wireless remote it would be a good
idea to test it at this time. There is no need to go all
the way to the limit switches since those were
tested above. Also check the mast light if you have
one. The lights come on when their buttons are
pressed and go off after about 15 minutes.
TROUBLE SHOOTING
OPTIONAL LIGHT SYSTEM
The optional light system has a circuit breaker on the
Advanced Switch Control (ASV) (Fig. 5 on page 6)
If the circuit breaker trips:
Step 1: Check to see if the light bulb(s) is good.
Step 2: Check to see if the wireless remote is working
by trying to raise and lower the lift. If the wireless
remote is not working, see the trouble-shooting steps on
page 10.
Step 3: Check wiring to make sure coating has not
rubbed away exposing the internal wires.
