DISTANCE TO HIGH VOLTAGE CABLES
Do not travel or operate the machine near electric cables. There
is a hazard of electric shock, which may cause serious injury or
property damage. On jobsites where the machine may go close to
electric cables, always do as follows.
q
Before starting work near electric cables, inform the local
power company of the work to be performed, and ask them to
take the necessary action.
q
Even going close to high-voltage cables can cause electric
shock, which may cause serious burns or even death. Always
maintain a safe distance (see the table on the right) between
the machine and the electric cable. Check with the local
power company about safe operating procedure before start-
ing operations.
q
To prepare for any possible emergencies, wear rubber shoes
and gloves. Lay a rubber sheet on top of the seat, and be
careful not to touch the chassis with any exposed part of your
body.
q
Use a signalman to give warning if the machine approaches
too close to the electric cables.
q
When carrying out operations near high voltage cables, do not let anyone come close to the machine.
q
If the machine should come too close or touch the electric cable, to prevent electric shock, the operator should
not leave the operator's compartment until it has been confirmed that the electricity has been shut off.
Also, do not let anyone come close to the machine.
ENSURE GOOD VISIBILITY
q
Check for any persons or obstacles in the area around the machine and check the conditions of the jobsite to
ensure that operations and travel can be carried out safely. Always do as follows.
q
Position a signalman if there are areas at the rear of the machine where the visibility is not good.
q
When working in dark places, turn on the working lamp and front lamps installed to the machine, and set
up additional lighting in the work area if necessary.
q
Stop operations if the visibility is poor, such as in mist, snow, rain, or dust.
VENTILATION FOR ENCLOSED AREA
Exhaust fumes from the engine can kill.
q
If it is necessary to start the engine within an enclosed area,
or when handling fuel, flushing oil, or paint, open the doors
and windows to ensure that adequate ventilation is provided
to prevent gas poisoning.
