11. Next using the 3/8 x 1 ½ shoulder screw provided, connect the Cross Rail chain
to the chain anchor welded to the base plate of the Main side Leg (
see Fig. 5C
).
Next move the Cross Rail over the chain connector. IMPORTANT – The chain
must be in a vertical position. It cannot be cocked towards the front or rear of the
chain anchor (
See Fig. 5C
)
12. Step #4, repeat steps #3 on the other Main side Leg and Cross Rail.
13. Step #5, positions each Offside Leg about 6” from the end of each Cross Rail,
and put a 4 x 4 board under each Cross Rail.
14. Step #6, connect threaded chain connector to free end of chain using the 3/8 x 1
¼ shoulder screw provided (
see Fig. 5D
). Run threaded chain connector into the
hole from the inside to the top of Offside Leg. Run 2–1 1/8-12
UNF
hex nut all the
way down until connector is flush with the top of the hex nut. Repeat step #5 &
#6 on other Cross Rail.
15. Step #7, Move Offside Legs inside chalk line hold 20’-5 ½” from center to center
of legs. You can go ahead and drill the holes for the anchor bolts on the Offside
Leg per the Anchoring Tip Sheet. Leave the bolts loose until the legs are
plumbed and the lift is operating without getting in a bind.
16. Step #8, extend hydraulic cylinder, which lower both Top Rail chain to connect
them to the chain connectors on Cross Rail (
see Fig. 5E
). This is done by
removing the breather from rear of the cylinder as shown in see Fig. #1. Pull on
the chain to extend the cylinder rod. Use the 3/8 shoulder screw (2 pcs–
91259A640) and 5/16-18UNC nylon lock nut (2 pcs–90640A130) to secure the
chain. Do not substitute this bolt! Repeat on other Cross Rail. Then place
breather back on cylinder.
17. Step #9 is to mount the power unit to the Main side Leg with the mounting
brackets using 5/16-18
UNC
x 1” bolts, 5/16-18
UNC
hex nuts and 5/16 lock
washers respectively. Then connect power unit to the hydraulic cylinder using a
3/8 hydraulic hose (ALIF-412-029). Next connect the electricity to the power unit.
Power requirements: 230 Volt, single-phase power, and 29 amps. Requires a
minimum of 10-gage wire (prefer 8-gage wire). Use separate circuit for each unit
and protect each circuit with 30-amp time delay fuse or circuit breaker.
18. Fill pumping unit with 10wt anti-foam, anti-rust hydraulic oil or ATF Dexron
III
.
Do Not Use oils with Detergents.
19. Step #10 is to connect the 3/8 hydraulic hose from the power unit to the cylinder.
Next secure the 3/8 hydraulic hose using the ¾ rubber cushion steel loop (4 pcs–
3225T6) and #10 x ½ self-threading screws (4 pcs-90096A242) (
see Fig. 6B
). A
#19 drill is used to drill the holes for the #10 self-threading screws.
20. Step #11 is to connect the pneumatic control valve to the 1 1/16 diameter
cylinders using the components shown in Fig. #6a & #6B. Secure the 5/32 black
tube next to the control valve with a ¼ plastic loop and a #10 self-threading
screw.
21. Before operating lift visually inspect lift to make sure the chains and hoses are
not rubbing on hardware or lift parts. Also make sure long chain is not twisted
inside Top Rail tube. DO NOT TIGHTEN THE ANCHORS ON THE OFFSIDE
LEGS YET.
