TROUBLE-SHOOTING
ANCHOR BOLTS DO NOT TIGHTEN, OR PULL OUT OF FLOOR
1] Faulty concrete, or insufficient floor thickness: Have floor checked for proper specifications.
2] Wrong size drill bit size was used. Move the lift and drill new holes with the correct size bit.
LIFT DOES NOT RISE; NO MOTOR NOISE
1] No power: Check breaker, power to Power Unit; verify proper wiring.
2] Bad switch: Check, replace if necessary.
3] Cut-off switch engaged (if present): Verify wiring of cut-off switch.
4] Bad motor: Repair or replace.
MOTOR RUNS, BUT LIFT DOES NOT RISE
1] No draw from pump: Verify fluid is flowing through hose. Check pick-up tube inside reservoir.
2] Check lowering valve for debris or bad o-ring. Inspect check-valve, if present.
3] Bad pump: repair or replace.
4] Bad motor: Repair or replace.
LIFT RAISES, BUT LABORS
1] Wrong Voltage: Lift may be wired at 110vac; verify 220vac.
2] Improper flow: Check pressure rating of pump, and verify out-put.
3] Vehicle too heavy for lift: Verify weight of vehicle.
4] Bad power unit: Repair or replace.
LIFT SHUDDERS OR SHAKES WHEN RAISING OR LOWERING
1] Mechanical Binding: Inspect and correct.
2] Incorrect fluid used: Verify AW-32, and replace incorrect fluid if necessary.
3] Air in lines: Should bleed through reservoir cap; check for restrictions. Bleed manually if necessary.
LIFT RAISES TOO SLOWLY
1] Wrong voltage or fluid flow (see above).
2] Excessive weight (see above).
3] Mechanical binding in structure: Inspect for binding; verify the plum and square of installation.
4] Hydraulic flow is restricted: Check hoses and fittings for blockage. Check lowering valve for by-pass.
CARRIAGES RAISE UNEVENLY
1] Uneven distribution of weight: Vehicle improperly loaded or out of balance. Re-check and correct.
2] Cables out of adjustment: Readjust. Check cables for stretching, fraying or wear. Replace if necessary.
3] Unequal hydraulic fluid flow: Check hoses and fittings for restrictions.
4] Mechanical binding in one tower: Check and correct as necessary.
CARRIAGE LOCKS DO NOT ENGAGE, OR ENGAGE OUT OF SYNC
1] Carriages are not raising evenly: (See above.)
2] Locking mechanism(s) are dirty or require lubrication: Lubricate with WD-40, or similar oil.
3] Locks are restricted: Check and verify release cable or locking mechanism is not restricted, or jammed.
4] Defective components: Inspect and correct or replace as necessary.
5] Grease or oil on inside of post is preventing the latch from resetting.
LIFT LOWERS UNEVENLY
1] Uneven distribution of weight: Vehicle improperly loaded or out of balance. Re-check and correct.
2] Mechanical binding: Inspect and correct.
3] Hydraulic restriction: Inspect and correct.
4] Cables out of adjustment: Inspect and correct.
LIFT LOWERS SLOWLY
1] Mechanical binding: Inspect and correct.
2] Hydraulic restriction: Inspect and check. Check Lowering valve for dirt, debris or defect. Clean or replace.
LIFT LOWERS TOO QUICKLY
1] Wrong fluid used in lift: Verify AW-32, and replace incorrect fluid if necessary.
2] Improper Hydraulic Flow: Check for leaks, or defective flow-restrictors or lowering valve.
LIFT WILL NOT COME DOWN
1] Verify Carriage Locks are disengaged.
2] Check for mechanical binding or restriction. Verify carriages are level.
3] Consult professional.
