GENERAL PRECAUTIONS
SAFETY AT WORKSITE
q Before starting operations, thoroughly check the work area
for dangerous working conditions.
q Inspect the surface of the soil in the working area and
determine the optimum and safest procedure.
q When carrying out operations near combustible materials
such as thatched roofs, dry leaves or dry grass, there is a
hazard of fire, so be careful when operating.
q Determine the required safety measures against dangers
on public roads in co-operation with the owners, users, and
responsible authorities.
q On sites where there are underground water pipes, gas
pipes, or conduits for high voltage cables, contact the
responsible supply company to determine the lines' posi-
tions. Ensure that these facilities will not be damaged.
q When working with water or crossing sand banks, first
check the subsoil and depth and flow rate of the water.
Ensure that the permitted water depth will not be
exceeded.
q Take action to prevent unauthorized people from approach-
ing the jobsite.
WORKING ON LOOSE GROUND
q Do not drive the machine too close to edges of hills, overhangs, and deep ditches.
q If the soil starts to sag at these locations, the machine may tip over, fall down, or roll over, thus injuring you
severely.
q Take into account that the soil is wet and soft after heavy rainfall, or very loose after blasting.
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.
