SAFETY
GENERAL PRECAUTIONS
2-19
DO NOT GO CLOSE 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 starting 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 near 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 con-
firmed that the electricity has been shut off.
Also, do not let anyone near the machine.
ENSURE GOOD VISIBILITY
This machine is equipped with mirrors to improve the visibility, but even with mirrors, there are places, which can-
not be seen from the operator's seat, so always be careful when operating.
When operating or traveling in places with poor visibility, if it is impossible to confirm the condition of the job side or
obstacle is in the area around the machine, there is danger that the machine may suffer damage or the operator
may suffer serious personal injury. When operating or traveling in places with poor visibility, always observe the
following items strictly.
q
If the visibility cannot be sufficiently assured, position a flagman if necessary. The operator should pay careful
attention to the signs and follow the instructions of the flagman.
q
The signals should be given only by one flagman.
q
When working in dark places, turn on the working lamps and front lamps of the machine, and if necessary, set
up additional lighting in the area.
q
Stop operations if there is poor visibility, such as in fog, snow, rain, or sand storms.
q
Check the mirrors on the machine before starting operations every day. Clean off any dirt and adjust the view
to ensure good visibility.
