Genie Articulated Boom Lift ZXq135/70

Required maintenance procedures and additional engine information are available in the manufacturer's manuals. Refer to Specifications, Engine Operator and Maintenance Manuals

• Valve clearance - check/adjust

• Bolts, nuts and fasteners - check/tighten

- Grease the Turntable Rotation Bearing and Rotate Gear

Perform this procedure more often if dusty conditions exist and when operating the machine in high temperature environments

Frequent application of lubrication to the turntable bearing and rotate gear is essential to good machine performance and service life. Continued use of an improperly greased bearing and gear will result in component damage

1. Locate the grease fitting for the turntable rotate bearing

2. Pump grease into the turntable rotation bearing. Rotate the turntable in increments of 4 to 5 inches / 10 to 13 cm at a time and repeat this step until the entire bearing has been greased

3. Models with Drive Gear: Apply grease to each tooth of the drive gear, located under the turntable

Models with Worm Drive Gear: Grease each tooth on the outside of the turntable rotation bearing

1. Locate the 2 grease fittings on top of the worm drive housing

- Inspect the Tires, Wheels and Lug Nut Torque

- Grease the Turntable Rotation Bearing and Rotate Gear

- Check the Turntable Rotation Bearing Bolts

- Replace the Hydraulic Filters;

- Test the Safety Envelope and Circuits - S-100, S-105, S-120, S-125, S-100HD and S-120HD

Testing the machine safety envelope is critical to safe machine operation. If the boom is allowed to operate when a safety switch is not functioning correctly, the machine stability is compromised and may tip over

Note: Use the following chart to identify the description of each LCD screen control button used in this procedure

1. Start the engine from the ground controls

2. Raise the boom to approximately 60°

S-100, S-105 and S-100HD Models: Proceed to step 28

101 feet / 30.8 m Length Safety Switch, LSB2RS:

3. Extend the boom to more than 80 feet / 24.4 m

4. Push in the red Emergency Stop button to the off position

- Check the Turntable Rotation Gear Backlash - ALC1000 Models

Properly adjusted turntable rotation gear backlash is essential for good machine performance and service life. Improperly adjusted turntable rotation gear backlash will cause the machine to perform poorly and continued use will cause component damage. The turntable rotation drive hubs are mounted on an adjustable plate on the swing chassis behind the fixed side cover at the ground controls side of the machine

This procedure does not apply to the Z-60/80 models

Note: Perform this procedure with the machine fully stowed and the counterweight at the square end of the machine

Note: Perform this procedure with the machine on a firm, level surface that is free of obstructions

1. Rotate the turntable until the boom is centered between the circle end wheels

2. Apply approximately 20 lbs / 89 N of side force to the platform, moving the platform to one side as far as it will go

3. Using a feeler gauge, measure the gap between the swing hub pinion gear and the turntable rotation bearing at the center tooth on one of the drive hubs. The gap should be measured on one side of the pinion gear on the center tooth

Note: The pinion gear can be accessed on the outside of the chassis under the pinion gear guard
