Genie Articulated Boom Lift Z-34/22 DC

Warning: Two people are required to perform this procedure.

Perform this procedure with the engine at normal operating temperature.

Connect an rpm gauge to the engine, and then start the engine from the ground controls. Enter the rpm reading.

If the low idle rpm is not correct, proceed to step 6.

Did you adjust the low idle rpm by loosening the lock nut and turning the low idle adjustment screw?

Recheck the rpm after adjustment. Enter the new rpm reading.

Move the engine idle control switch to high idle (rabbit symbol) from the ground controls. Is the high idle rpm 3000?

If the high idle rpm is not correct, proceed to step 10.

Warning: This procedure requires trained personnel!

Key switch turned to ground control and red Emergency Stop button in the on position

Boom lowered to the stowed position

Platform adjusted to a level position

Primary boom raised and lowered through a full cycle

Enter the platform level in degrees

Sign off on the platform self-leveling test

Warning: Collision hazard. Be sure that the machine is not in free-wheel or partial free-wheel configuration. Refer to maintenance procedure, Confirm the Proper Brake Configuration.

Note: Select a test area that is firm, level and free of obstructions.

Mark a test line on the ground for reference.

Lower the boom to the stowed position.

Turn the key switch to platform controls.

Choose a point on the machine (i.e., contact patch of a tire) as a visual reference for use when crossing the test line.

Bring the machine to top drive speed before reaching the test line. Release the drive joystick when your reference point on the machine crosses the test line.

Measure the distance between the test line and your machine reference point.

Connect the leads from an ohmmeter between the far left glow plug and ground.

Enter the resistance reading. The resistance should be approximately 1Ω.

If the ohm reading is different than 1Ω, remove the wire and connector plate from the three individual glow plugs. Then, one glow plug at a time, measure the resistance between the glow plug and ground.

Enter the resistance reading for each individual glow plug. The resistance should be approximately 1.8Ω for each individual glow plug.

Turn the key switch to ground control and pull out the red Emergency Stop button to the on position.

Connect the red positive (+) lead from a volt meter to one of the glow plugs. Connect the black negative (-) lead to ground.

Hold the glow plug switch in the on position.

Enter the volt meter reading. The volt meter should read 12V DC or more.

Repeat steps 4 and 5 for the other glow plug.
