Safety locks may not engage at exactly the same time
when vehicles are being raised. They should be close. Be
sure that all four corners have passed the SAME safety
ladder bar slot before lowering lift on the safety locks.
NEVER lower lift on different safety lock position or dam-
age to the lift may result.
STEP 18
(Adding Grease)
1. Lift must be fully lowered before changing or adding fluid.
2. Add grease fittings to the locations shown on page 44. If
the grease fittings are already installed, skip this step.
3. Add grease to the grease fittings.
STEP 19
(Bleeding)
1. Lift must be fully lowered before changing or adding fluid.
2. Raise and lower lift six times. The cylinder is
self-bleeding. After bleeding system, fluid level in power unit
reservoir may be down. Add more fluid if necessary to raise
lift to full height. It is only necessary to add fluid to raise lift
to full height.
3. To pressure test, run lift to full rise and run motor
for approximately 3-seconds after lift stops. This will place
pressure on the hydraulic system. Stop and check all
fittings and hose connections. Tighten or reseal if required.
