
Be Certain All Fittings and Connections are Tight. It is the installers responsibility
to ensure system is leak-free.
Fill the Power Unit with three gallons of clean ISO 32
(10 weight) hydraulic oil. Do Not Use Oils with any detergent additives.

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.

Install 4mm safety release air line from air valve assembly thru opening in runway to
Tee fitting, Figure 17 .

Pull out all 4mm release poly tube stored inside cross beam, route power side front and
rear cross beam air lines through power runway to Tee fitting. Route idler side front and
rear cross beam air lines through idler runway and connect together with 4mm poly tube
splice provided. Route airline through welded rings on the outside internal edge of
runways,
Figures 17, 19 and 20 .

Remove the lubricator cap from lubricator and fill with Snap-on Air Tool oil or equivalent,
reservoir should be 80% full.
Connect air source to the filter and adjust the pressure to 90
- 120 PSI. Adjust
the drop speed to be 2-3 drops per minute.

Air supply must be clean, dry, lubricated, and regulated to 90-120 psi. Failure to
provide clean, dry, lubricated, and pressure regulated air will void warranty on
pneumatic components.

Energize air valve assembly and make sure that all air cylinders are working properly.

Level the runways and crossbeams using laser level and height gauge. With the lift
resting in its locks, place the laser level at appropriate location. Place height gauge at all
four corners of cross beams and adjust location of laser level to ensure all four corners
are within laser range. Find the highest corner and adjust the other three column ladder
bars until reach the same reading from height gauge of all four corners. Tighten jam nut
against bottom side of each column top plate.

Adjust cables until all four cables are tight and locks synchronized when lift is raised.
(One should be able to hear a click sound when lock engages, all four engage sound
should happen at the same time.) Tighten cable jam nuts against adjustment nuts.

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.

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.
