• The ROPS must be replaced if a overturn incident occurs. The protection

offered by the ROPS will be impaired if it has been damaged in an

overturn incident.

• Never operate the machine without a ROPS or FOPS installed.

Electrical Energy

• Stay away from high-voltage lines. Serious injury or death can result from

contact or proximity to high-voltage electric lines. The machine does not

have to make physical contact with power lines for current to be

transmitted. Use a spotter and hand signals to keep away from power lines

not clearly visible to the operator.

• Depending upon the voltage in the power line and atmospheric conditions,

strong current shocks can occur if the bucket is closer than 3 m (10 ft.) to

the power line. Very high voltage and rainy weather can further increase

the safe operating distance.

• If the machine comes into contact with a live wire:

- Do not leave the machine.

- If possible, drive the machine out of the danger area.

- Warn others not to approach or touch the machine.

- Have the live wire de-energized.

- Do not leave the machine until the wire has been safely de-energized.

• Work on the machine’s electrical system must be performed only by

trained technicians.

• Inspect and check the machine’s electrical equipment at regular intervals.

Problems found, such as loose connections or scorched cables, much be

repaired before using the machine.

• Only use proper, original equipment fuses/circuit breakers with the

specified current rating. Turn off the machine immediately if there is any

indication of a problem with the electrical system.

Service Safety Practices

• Only trained and authorized personnel, with a full awareness of safe

procedures, should be allowed to operate or perform maintenance or

service on the machine.

• Use warning tag/control lockout procedures during service. Alert others

that service or maintenance is being performed by tagging operator’s

controls — and other machine areas if required — with a warning notice.

• Never attempt to bypass the keyswitch to start the engine. Use only the

proper jump-starting procedure explained in “Using a Booster Battery

(Jump-Starting)” on page 142.
