1. Supply correct voltage to motor

2. Clean lowering valve

3. Replace relief valve cartridge

4. Check vehicle weight and/or balance vehicle weight on lifts.

Lift slowly settles down

1. Trash in check valve seat

2. Trash in lowering vale seat

3. External oil leaks

2. Clean lowering valve

3. Repair external leaks

Slow lifting speed or oil blowing out filler breather cap

1. Air mixed with oil

2. Air mixing with oil in suction tube

3. Oil return tub loose.

1. Change oil to

    Dexron II ATF

2. Tighten all suction line fittings

3. Reinstall oil return tube

Lift going up unevenly

1. Equalizer cable out of adjustment

2. Lift installed on unevenly floor

1. Adjust equalizer cables to current tension

2. Shim lift to level columns (Not to exceed 1/2”).  If over 1/2” break out floor and level

Anchors will not stay tight

1. Holes drilled oversize

2. Concrete floor thickness or holding strength not sufficient

1. Use a fast setting cement to pour into oversize holes and reset anchors–or-relocate lift using a new bit to drill holes.

2. Break out old concrete and re-pour new pads for lift

Locking latches not resetting

1. Coupling nut on reset rod missing or not adjusted.

1. Install or adjust coupling nut so latches will reset when lift is completely lowered.

Locking latches do not operate

1. Dog pivot pins rusted. (Usually occurs on outside installations or in high humidity areas such as vehicle wash bays.)

2. Dog pivot spring broken

1. Raise lift to full travel, pour a little oil down back side of each carriage on to the latch mechanism while activating reset lever.
