PRECAUTIONS FOR OPERATION SAFETY
2-20
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 ensure good visibility, but even then there are places that cannot be seen
from the operator's seat, so be careful when operating.
Before traveling or operating the machine, the operator should sound the horn to warn people in the area.
When traveling or carrying out operations in places with poor visibility, it is impossible to check for obstacles in the
area around the machine and to check the condition of the jobsite. This leads to danger of serious personal injury
or death. When traveling or carrying out operations in places with poor visibility, always observe the following.
q Position a signalman if there are areas where the visibility is not good.
q Only one signalman should give signals.
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.
q When checking the mirrors installed to the machine, remove all dirt and adjust the angle of the mirror to ensure
good visibility.
CHECKING SIGNS AND SIGNALMAN'S SIGNALS
q Set up signs to inform of road shoulders and soft ground. If the visibility is not good, position a signalman if
necessary. Operators should pay careful attention to the signs and follow the instructions from the signalman.
q Only one signalman should give signals.
q Make sure that all workers understand the meaning of all signals and signs before starting work.
