PRECAUTIONS FOR JOBSITE
INVESTIGATE AND CONFIRM JOBSITE CONDITIONS
On the jobsite, there are various hidden dangers that may lead to personal injury or death. Before starting
operations, always check the following to confirm that there is no danger on the jobsite.
Check the terrain and condition of the ground at the worksite, and determine the safest method of operation. Do
not operate where there is a hazard of landslides or falling rocks.
Take necessary measures to prevent any unauthorized person from entering the operating area.
When traveling or operating in water or on soft ground, check the water depth, speed of the current, bedrock, and
shape of the ground beforehand and avoid any place that will obstruct travel.
Maintain the travel path on the jobsite so that there is no obstruction to travel operations.
WORKING ON LOOSE GROUND
Avoid traveling or operating your machine too close to the edge of cliffs, overhangs, and deep ditches. The
ground may be weak in such areas. If the ground should collapse under the weight or vibration of the machine,
there is a hazard that the machine may fall or tip over. Remember that the soil after heavy rain or blasting or after
earthquakes is weak in these areas.
When working on embankments or near excavated ditches, there is a hazard that the weight and vibration of the
machine will cause the soil to collapse. Before starting operations, take steps to ensure that the ground is safe
and to prevent the machine from rolling over or falling.
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 personal
injury or death. On jobsites where the machine may go close to
electric cables, always do as follows.
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.
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.
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.
Use a signalman to give warning if the machine approaches too
close to the electric cables.
Voltage of Cables Safety Distance
100V - 200V Over 2 m (7 ft)
6,600V Over 2 m (7 ft)
22,000V Over 3 m (10 ft)
66,000V Over 4 m (14 ft)
154,000V Over 5 m (17 ft)
187,000V Over 6 m (20 ft)
275,000V Over 7 m (23 ft)
500,000V Over 11 m (36 ft)
When carrying out operations near high voltage cables, do not let anyone near the machine.
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 near the machine.
