WARNING! Hot oil and components could cause serious injury. Do not allow hot oil or components to contact your skin.

Remove the hydraulic tank filler cap only after the engine has been stopped and the cap is cool enough to remove with your hands.

Remove the hydraulic tank filler cap slowly to relieve pressure.

Operate the lift truck for a few minutes to warm the oil.

Park the lift truck on a level surface, with the forks lowered, mast tilted back, parking brake applied, transmission in NEUTRAL, engine stopped and the wheels blocked.

Remove the hydraulic tank filler cap by turning it counterclockwise.

Check oil level on the dipstick.

Add oil needed to raise it to the correct level range on the dipstick.

Put the hydraulic tank filler cap back on.

Park the lift truck on a level surface, parking brake applied, transmission in NEUTRAL, forks lowered, lubricant warm, engine stopped and the wheels blocked.

WARNING! At operating temperature, the engine coolant is hot and under pressure. Steam could cause injuries. DO NOT let it contact your skin and eyes.

To avoid having scalding coolant or steam blow out of the radiator, do not remove the radiator cap unless the engine is cold.

Muffle the cap in a thick cloth and turn it slowly to release all pressure before removing the cap.

The lift truck must be level, the forks lowered, the parking brake applied, the transmission in NEUTRAL, engine stopped and the wheels blocked. The engine must be cooled down.

Maintain the coolant level between the FULL and LOW marks on the reserve tank.

WARNING! Keep fire away from undiluted antifreeze as it is FLAMMABLE

CAUTION! DO NOT add water only. This dilutes the antifreeze/summer coolant protection and adversely affects the engine. Be sure to premix antifreeze/summer coolant with tap water (soft water).

If coolant has to be added frequently, have your Cat lift truck dealer check the cooling system.

WARNING! Check the lift chains periodically and determine if they are still in usable condition. Check the lift chains for wear, cracks and worn or seized link pins. Improper maintenance of the lift chains can cause accidents. If something is wrong with the chains, consult your Cat lift truck dealer for repair or replacement. DO NOT put your foot under the fork.

Check the lift chains for wear. Use the following chart to determine if it is still in usable condition.

Lift Chain Elongation Limit:(/20 links)

Lift the forks high enough to put their full weight on the carriage and chains.

Check to be sure the lift chains have equal tension.

If the chains are loose or the tension is not equal, have the chains adjusted.

Loosen the locknut 1 and the nut. Then turn the nut to adjust tension.

Hold the nut and tighten the nut to torque A. Hold the nut 3 and tighten the locknut to torque B.

WARNING! Hot oil and components could cause serious injury. Do not allow hot oil or components to contact skin.
