34) Remove the 3/8-18 NPT plug on the side of
the power unit and replace with the 3/8-18
NPT x 9/16-18 adapter and attach the 90
degree elbow to the adapter,

.
Fig 16 – Return Line, Side
NOTE: When attaching the return line to the
bulk head in the runway, make sure it is
securely attached at the power unit, and the
hose is not twisted or torque in a position that
will lead it to getting caught on the power unit
reservoir. 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.
35) 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.
36)
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 15 amp single throw
circuit breaker to operate lift at full capacity.

38) 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.
39) 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.
40)
Adjust cables until all four locks are
synchronized when lift is raised. Tighten
cable jam nuts against adjustment nuts.
41) 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.
42) 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.
