Clark Electric Rider Lift Trucks GTX 20s

Warning: Do not attempt to repair a worn chain. Lift chain repairs and adjustments should be made by trained service personnel.

Inspect and lubricate the lift chains every PM (50-250 hours). When operating in corrosive environments, inspect the chains every 50 hours.

Check for corrosion, cracked plates, raised or turned pins, tight joints, wear, and worn pins or holes.

Measure chain wear. When a section of chain is 3% longer than a section of new chain, the chain is worn and must be discarded.

Do not repair chains by cutting out the worn section and joining in a new piece. If part of a chain is worn, replace all the chains on a truck.

Replace all chains as a set. Do not remove factory lubrication or paint new chains. Replace anchor pins and worn or broken anchors when installing new chains. Adjust tension on new chains. Lubricate chains when they are installed on the upright.

NOTICE! The steering system, steer axle, and steering linkage on your truck should be inspected periodically for abnormal looseness and damage, leaking seals, etc. Also, be alert for any changes in steering action. Hard steering, excessive free play (looseness), or unusual sound when turning or maneuvering indicates a need for inspection or servicing.

Check the steering system by moving the steering handwheel in a full right turn and then in a full left turn.

Return the handwheel (steer wheels) to the straight ahead position.

The steering system components should operate smoothly when the steering wheel is turned.

IMPORTANT! Never operate a truck with a malfunctioning steering system.

Begin the PM routine with a visual inspection of the lift truck and its components.

Walk around the truck and take note of any obvious damage and maintenance problems. Check for loose fasteners and fittings.

Check to be sure all capacity, safety, and warning plates or decals are attached and legible.

NOTICE! NAMEPLATES AND DECALS: Do not operate a lift truck with damaged or lost decals and nameplates. Replace them immediately. They contain important information.

Inspect the truck for any sign of external leakage: transmission fluid, brake oil, electrolyte, etc.

Check for hydraulic oil leaks and loose fittings.

CAUTION! HYDRAULIC FLUID PRESSURE: Do not use your hands to check for hydraulic leakage. Fluid under pressure can penetrate your skin and cause serious injury.

Be sure that the driver's overhead guard, load backrest extension, and safety devices are in place, undamaged, and attached securely.

Then check all of the critical components that handle or carry the load.

Check the function of the lift system and controls

Pull back on the tilt control lever and hold until the upright reaches the full back tilt position

Push forward on the lever to return the upright to the vertical position

Release the lever. It should spring back to the neutral position freely without assistance

Pull back on the lift control lever and raise the fork carriage to full height

Watch the upright assembly as it rises. All movements of the upright, fork carriage, and lift chains must be even and smooth, without binding or jerking

Watch for chain wobble or looseness; the chains should have equal tension and move smoothly without noticeable wobble

Release the lever. It should spring back to the center position

If the maximum fork height is not reached, this indicates there is an inadequate (low) oil level in the hydraulic sump tank or severe binding within the upright

Warning: This maintenance task requires trained personnel with PPE!
