12. Electrical:
Have a certified electrician run
appropriate power supply to motor, Fig. 21 & 22. Size
wire for 20 amp circuit. See Motor Operating Data Table.
CAUTION
Never operate the motor on line voltage less
than 208V. Motor damage may occur.
IMPORTANT:
Use separate circuit for each power unit.
Protect each circuit with time delay fuse or circuit breaker.
For single phase 208-230V, use 20 amp fuse. Three phase
208-240V, use 20 amp fuse. For three phase 400V and
above, use 10 amp fuse. For wiring see Fig. 21 & Fig. 22.
All wiring must comply with NEC and all local electrical
codes.
Note:
60Hz. single phase motor
CAN NOT
be run on
50Hz. line without a physical change in the motor.
13. Overhead switch:
Check overhead switch assembly
to assure that switch bar is depressing switch plunger
sufficiently to actuate the switch. The overhead switch
is wired normally open, see Fig. 15a, Fig. 16a, and Fig.
16b. Lift will not operate until weight of switch bar is
depressing switch plunger. Verify that Power Unit stops
working when switch bar is raised, and re-starts when the
bar is released.
CAUTION
When bleeding, hold a shop cloth over
bleeder screw to buffer the air and fluid while bleeder
valve is open.
14. Oil Filling & Bleeding:
Use Dexron III ATF, or
Hydraulic Fluid that meets ISO 32 specifications. Remove
fill-breather cap, Fig. 15b. Pour in (8) quarts of fluid.
Start unit, raise lift about 2 ft. Open cylinder bleeders
approx. 2 turns, Fig. 9.
Close bleeders when fluid streams. Fully lower lift. Add
more fluid until it reaches fill line on the tank. System
capacity is (14) quarts. Replace fill-breather cap.
CAUTION
If fill-breather cap is lost or broken, order
replacement. Reservoir must be vented.
