that will lead to getting caught on the power
unit reservoir or the stud on the column
sides. Raise the lift and carefully watch the
path the hose is riding up the column, adjust
connection at the power unit and/or runway
bulkhead to allow the hose to move up
between the power unit and column. Make
sure the hose doesn’t catch on the column
caster lug as the lift rises...
36) Install O-Ring end of the straight hydraulic
fitting (9/16-18 O-Ring x M14x1.5-6g) to
power unit output port. Connect the
hydraulic hose to the hydraulic bulkhead
fitting in the power runway.
Do Not Use Teflon Tape or Pipe Dope
on
fittings.
37)
Connect the power unit to a suitable
electrical power source. The standard power
unit is 115 volt 50/60 Hz single phase
requiring a dedicated single throw circuit
breaker to operate lift at full capacity. For
230V power unit, refer to
Fig 22
.

39) Energize the power unit and raise the lift
approximately 1 ft off the ground and look
underneath the power runway to verify that
the cable lugs are resting firmly against the
cylinder pull bar and all cables are routed
properly, riding in sheaves correctly and not
crossed.
40) Raise lift to working height and lower lift onto
locks. Attach the mechanical lock bar to both
cross beams using the hairpin cotter pins,
make sure the lock bar is positioned onto the
saddle/hook inside the runway.
Verify the
mechanical lock release moves freely and
lock pawl return spring doesn’t interfere
with Lock Ladder.(See Fig 4)
41) To level the runways and crossbeams use a
4 ft. level. With the lift resting in its locks, find
the highest corner and adjust the other three
column ladder bars until the runways are
level front-to-rear and side-to-side. Tighten
jam nut against bottom side of each column
top plate.
42)
Adjust cables until all four locks are
synchronized when lift is raised. Tighten
cable jam nuts against adjustment nuts.
43) Raise and lower lift several times to bleed
hydraulic cylinder. Hydraulic cylinder is self
bleeding. Lower lift and check fluid level in
reservoir. Add fluid as needed.
44) Run lift to full rise and continue running motor
approximately 5 more seconds. Check
hydraulic hose and connections for leaks.
Re-tighten fitting if leaking.
