7. TROUBLESHOOTING WARNING Prevent serious injury or death. Disconnect and/or lock out electrical supply to power unit prior to any maintenance being performed. ^ WARNING Prevent serious injury or death. Never go under lift platform until load is removed and scissors mechanism is securely blocked in open position. Follow OSHA lock-out/tag-out procedure. See "Maintenance Devices" section. ^ WARNING Pressurized fluids can penetrate the skin. Hydraulic hoses can fail from age, damage and exposure.
PROBLEM Lift Raises, Slowly. Then Lowers POSSIBLE CAUSE AND SOLUTION Down solenoid may not be seating. Remove solenoid coil and check. If lift does not hold with solenoid coil removed, remove and clean down valve cartridge or replaced as necessary. Oil line, hose, or fitting may be leaking. Check and repair if necessary. Lift Lowers Slowly. Check valve in pump assembly may not be seating. This is indicated by pump shaft and motor turning backward on their own with no power applied.
PROBLEM Lift Does Not Raise, Continued. POSSIBLE CAUSE AND SOLUTION Breather holes in reservoir fill plug may be clogged. Remove and clean. Voltage may be too low to run pump with existing load. Check by measuring voltage at motor terminals, or as near as possible, while pump is running under load. Inadequate or incorrect wiring can starve motor when source voltage is ample. Correct as necessary. Down valve may be energized by faulty wiring or stuck open. Remove solenoid and check.
PROBLEM Lift Seems During Operation. Bouncy Motor Labors Or Heats Excessively. POSSIBLE CAUSE AND SOLUTION Lower lift to collapsed position and continue to hold “DOWN” button an additional 10-30 seconds to bleed air from cylinder. Do not confuse spongy or jerky operation with small surges that may occur when operating on rough or uneven floors. Check for oil starvation. Voltage may be low. Check voltage at motor terminals while pump is running under load, not at line source or while pump is idling.
