• Never perform unauthorized modifications on the Liftgate. Modifications may result in early failure of the Liftgate and may create hazards for Liftgate operators and maintainers. • Use only Maxon Authorized Parts for replacement parts. Provide Liftgate model and serial num- ber information with your parts order. Order replacement parts from: MAXON LIFT CORP.
PERIODIC MAINTENANCE CHECKLIST ! ! ! ! ! WARNING Never operate the Liftgate with parts loose or missing. Annually Visually check the entire Liftgate for excessively worn parts and broken welds, especially the Hinge Pins. See PARTS BREAKDOWN section for replacement parts. Also, do the Semi- annual and Quarterly Maintenance checks.
CHANGING HYDRAULIC FLUID CAUTION Keep dirt, water and other contaminants from entering the hydraulic system. Before opening the hydraulic fluid reservoir filler cap, drain plug and hydraulic lines, clean up contaminants that can get in the openings. Also, protect the open- ings from accidental contamination.
PLATFORM ADJUSTMENT Open and RAISE Platform to bed level as shown in Operation Manual M-00-40. Platform should be pointing up at bed level and pointing down at ground level (FIG. 2A and FIG. 2B). If the platform is level at bed height (FIG. 2C) and sags at ground level (FIG.

REPLACING PLATFORM TORSION SPRING 1. Manually fold Flipover onto Platform as shown in Operation Manual M-00-40. 2. Raise Liftgate to a convenient work height to gain access and release tension on the HAMMER Torsion Spring. CAUTION ! ! ! ! ! To prevent injury and equipment damage, make sure there is no tension on torsion spring before removing hinge pin.

5. Drive Platform Hinge Pin into correct position through the Platform Hinge Bracket with a hammer and pin punch as shown in (FIG. 7). Line up the hole in the Platform Hinge Pin with the hole in the Pin Collar. Install the roll pin through the Pin Collar until roll pin protrudes equally from both sides of the collar (FIG.
SAFETY HOOK MAINTENANCE GREASE FRONT SURFACE OF HOOK WITH AUTOMOTIVE GREASE GREASE ALL HOLES THE ROD PASSES THRU FIG. 8 EXTENSION PLATE CHECK SAFETY HOOK FUNCTION 1. When the Platform is raised to full “Stowed” position, SAFETY HOOK listen for an audible snap when Safety Hook engages the Platform Loop.

PLATFORM WILL NOT RAISE 1. Use voltmeter to verify that power is being supplied to Solenoid Terminal “A”. Recharge the battery if less than 12.6 volts. CAUTION Keep dirt, water and other contaminants from entering the hydraulic system. Before opening the hydraulic fluid reservoir filler cap, drain plug and hydraulic lines, clean up contaminants that can get in the openings.
PLATFORM RAISES BUT LEAKS DOWN COIL 1. Check if Solenoid Valves are constantly energized by touch- ing a screwdriver to the top nut of the Solenoid (FIG. 1). Try pulling the screwdriver away from the solenoid. If the solenoid nut attracts the screwdriver (magnetically) without pushing the toggle switch, the control circuit is operating incorrectly.
PLATFORM RAISES PARTIALLY AND STOPS CAUTION Keep dirt, water and other contaminants from entering the hydraulic system. Before opening the hydraulic fluid reservoir filler cap, drain plug and hydraulic lines, clean up contaminants that can get in the openings. Also, protect the openings from accidental contamination during maintenance.
LIFTGATE WILL NOT LIFT RATED CAPACITY 1. Use voltmeter to verify that the Battery shows 12.6 volts or more under load from pump motor. 2. Check for Structural damage or lack of lubrication.Replace worn parts. CAUTION ! ! ! ! ! Keep dirt, water and other contaminants from entering the hydraulic system.
PLATFORM RAISES SLOWLY 1. Use voltmeter to verify that power is being supplied to Solenoid Terminal “A”. Recharge the battery if volt- meter indicates less than 12.6 Volts ( FIG. 6). CAUTION Keep dirt, water and other contaminants from entering the hydraulic system.
PLATFORM WILL NOT LOWER, LOWERS TOO SLOWLY, OR LOWERS TOO QUICKLY 1. Use voltmeter to verify that power is being supplied to Solenoid Terminal “A”. Recharge the battery if voltmeter indicates less than 12.6 Volts ( FIG. 9). 2. Check for structural damage or poor lubrication. Replace worn parts.
