UL Label “EE”

Underwriters Laboratories (UL) ratings indicate that specific criteria are met by the manufacturer, and tested and documented by UL. “EE” designated lift trucks are electrically powered units that have, in addition to all of the requirements for “E” and “ES” units, electric components completely enclosed. In certain applications, an “EE” lift truck may be used where an “E” or “ES” lift truck may not be considered suitable.

•prolongs truck life

•reduces costly down time

•avoids unnecessary repairs

Scheduled maintenance includes:

•Lubrication

•Cleaning

•Inspection

•Service

Perform all of the scheduled checks and maintenance during the suggested intervals. The time intervals given in this guide are based on Deadman Hours (HD) under normal operating conditions.

What to do Refer to

BatteryCheck the weight stamped on the battery in the lift truck against the minimum and maximum allowable weights on the specification tag for the lift truck. Report any lift trucks that are running with batteries under the minimum or over the maximum allowable weight. Check for voltage leaks to frame. If cleaning does not remove voltage to frame, install a new battery. Inspect all battery connectors and leads for damage and cuts in protective coatings. Make sure the battery gates are in place and not damaged. Make sure the battery has no more than 0.5 inch (13 mm) free play in any direction.

Brakes In an open area, measure stopping distance. Traveling at 2 to 3 mph (3.2 to 4.8km/h.) empty, push the EPO switch; the empty lift truck should stop within 2 to 4 feet (0.6 to 1.2 m). During normal operation, with a rated load and traveling at top speed, the lift truck should stop within approx. one and one-half truck lengths. Stopping distance depends on the load, floor, and tire condition. Examine for signs of oil on the pads or rotor. If oil is present, disassemble brake, clean rotor, and replace the pads. Check brake gap.

Contactors Inspect contactor tips for burnt or pitted surfaces. Failure to replace the tips may prevent the contactor from opening or closing causing unscheduled downtime. With the key switch OFF and the battery disconnected, check the plunger for smooth operation with no binding. If binding occurs, the lift truck may malfunction or exhibit intermittent fault codes.

NOTE: For EE lift trucks, remove cover to inspect tips.

Control HandleVerify travel function is smooth and responsive through full range of motion. Check for play in center position of travel control. Verify all handle switches function correctly.

Deadman PedalCheck for smooth operation with no binding. Check correct activation and deactivation of the deadman switch by the pedal

Drive Unit Inspect for leaks. Check fluid level. Make sure O-ring is present on the dipstick. Examine for radial ring wear. Apply grease to the steer gear on the drive unit. Lubricate all grease points on the drive unit.

Electrical CablesInspect all power cables for nicks or cuts. Give special attention to those cables that are not stationary, for example, cables to the traction motor. Replace any cable that is damaged or shows signs of excessive heat. Failure to do so causes intermittent system shutdowns and/or electronic failures. Check the tension of the over-the-mast pulley cables. Set tension so the cables just stay on the pulleys. Higher tension causes premature failure. Maximum spring tension is 5 to 7 in. lb. (0.57 to 0.79 Nm).
