1. Have a certified electrician run the Power Supply to
motor. Refer to the data plate found on the motor for proper
power supply and wire size.
RISK OF EXPLOSION
This equipment has internal arcing or parts that may spark
and should not be exposed to flammable vapors. Motor
should not be located in a recessed area or below floor level.
NEVER expose motor to rain or other damp
environments. DAMAGE TO MOTOR CAUSED BY WATER
IS NOT COVERED UNDER WARRANTY.
STEP 14
(Inspecting The Slack Safety Springs)
The following steps involve the SLACK CABLE SAFETY
DEVICE and MAIN SAFETY. Failure to follow these steps
could result in serious injury or death in the event of cable
failure.
1. Inspect the ends of the ALL SAFETY LOCK SPRINGS
as shown. Make sure the spring ends are secure at both
ends.
DO NOT ATTEMPT TO RAISE THE LIFT UNTIL THE
SLACK SAFETY SPRINGS ARE ATTACHED AND THE
ROLLERS ARE PULLED CLEAR FROM THE LADDER.
(See Fig. 14.1)
2. Repeat this step for each corner of the lift.
STEP 15
(Lift Start Up / Final Adjustments)
1. Make sure the Power Unit reservoir is full with 12 quarts
of 10-WT hydraulic oil or Dexron-III automatic transmission
fluid.
2. Spray the inside of the Columns where the Slide Blocks
glide with a light lubricant or WD-40.
3. Test the Power Unit by pressing the push-button switch.
If the motor sounds like it is operating properly, raise the
lift and check all Hose Connections for leaks. If the motor
gets hot or sounds peculiar, stop and check all electrical
connections.
4. Before proceeding, double-check to make sure all Cables
are properly positioned within the grooves of ALL Sheaves.
Make sure all Cable Sheave retaining pins and/or clips are
secure.
IMPORTANT NOTE:
CAUTION Never operate the motor on line voltage
less than 208V. Motor damage may occur which is not
covered under warranty. Have a certified electrician run
appropriate power supply to motor. Size wire for 25
amp circuit. See Motor Operating Data Table.
IMPORTANT: Use separate circuit for each power unit.
Protect each circuit with time delay fuse or circuit
breaker. For single phase 208-230V, use 25 amp fuse.
Three phase 208-240V, use 25 amp fuse. For three
phase 400V and above, use 15 amp fuse. All wiring must
comply with NEC and all local electrical codes.
