Genie Articulated Boom Lift S85/2WD

- Inspect the Boom Extend/Retract Cables

Manufacturers specifications require that this procedure be performed by personnel that are competent in cable / wire rope inspection

Note: Additional or more frequent inspections may be required due to the following:

• exposed to hostile or corrosive environmental conditions

The boom extend/retract cables are responsible for the extension and retraction of the boom tubes

- Test or Replace the Hydraulic Oil

Replacement or testing of the hydraulic oil is essential for good machine performance and service life. Dirty oil and a clogged suction strainer or hydraulic filters may cause the machine to perform poorly and continued use may cause component damage. Extremely dirty conditions may require oil changes to be performed more frequently

Note: Before replacing the hydraulic oil, the oil may be tested by an oil distributor for specific levels of contamination to verify that changing the oil is necessary. If the hydraulic oil is not replaced at the 2000 hour inspection, test the oil quarterly. Replace the oil when it fails the test

Note: When removing a hose assembly or fitting, the O-ring (if equipped) on the fitting and/or hose end must be replaced. All connections must be torqued to specification during installation. Refer to Specifications, Hydraulic Hose and Fitting Torque Specifications

Complete the hydraulic oil testing with an oil distributor

If the hydraulic oil passes testing at the 2000 hour maintenance interval, the oil must be tested every quarter by an oil distributor until the oil fails the test and is replaced

If the hydraulic oil fails testing at the 2000 hour maintenance interval, the oil must be replaced

After the oil has been replaced, continue the scheduled quarterly maintenance inspection

Check for leaks Oil, fuel and coolant systems

Clean/replace air cleaner element

Check electrical wiring for chafing or damage

Warning: This procedure must be performed by personnel competent in cable/wire rope inspection.

Note: Additional or more frequent inspections may be required due to hostile or corrosive environmental conditions, boom overload, shock load, electrical arcing, or extended periods of disuse.

Inspect and adjust the boom extend/retract cables. Are they in good condition?

Inspect for foreign objects, damage and/or improper adjustment of the boom extend/retract cables and related components. Any issues found?

Check the boom extend and retract functions. Do they operate smoothly and free of hesitation, jerking and unusual noise?

Refer to the appropriate procedure for your model

- 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
