

Repair any machine damage or malfunction

before operating the machine.



Unless otherwise specified, perform each

procedure with the machine in the following

configuration:

•

Machine parked on a firm, level surface

•

Key switch in the off position with the key

removed

•

The red Emergency Stop button in the off

position at both the ground and platform

controls

•

Wheels chocked

•

All external AC power supply disconnected

from the machine

•

Platform in the stowed position

Before Troubleshooting:



Read, understand and obey the safety rules

and operating instructions in the appropriate

operator's manual on your machine.



Be sure that all necessary tools and test

equipment are available and ready for use.



Read each appropriate fault code thoroughly.

Attempting short cuts may produce hazardous

conditions.



Be aware of the following hazards and follow

generally accepted safe workshop practices.

Crushing hazard. When testing

or replacing any hydraulic

component, always support

the structure and secure it

from movement

Electrocution/burn hazard.

Contact with electrically charged

circuits could result in death or

serious injury. Remove all rings,

watches and other jewelry.

Bodily injury hazard. Spraying

hydraulic oil can penetrate and

burn skin. Loosen hydraulic

connections very slowly to allow

the oil pressure to dissipate

gradually. Do not allow oil to

squirt or spray.

Indicates that a specific result is expected

after performing a series of steps.

Indicates that an incorrect result has occurred

after performing a series of steps.

About This Section

When a malfunction is discovered, the fault code

charts in this section will help a service

professional pinpoint the cause of the problem.

To use this section, basic hand tools and certain

pieces of test equipment are required — voltmeter,

ohmmeter, pressure gauges.
