2.3 Precautions during operation Safety
2-22
WA80M-7, WA100M-7 – VENAM03001
Precautions in cold areas
 Allow the machine to warm up for a maximum of 20 minutes.
If the machine is not thoroughly warmed up before the control
levers are operated, the reaction of the machine will be slow,
which can lead to unexpected accidents.
 If the battery electrolyte is frozen, do not charge the battery
or start the engine with a different power source. There is a
hazard of the battery ingniting or exploding.
Before charging or starting the engine, allow the battery fluid
to thaw slowly and ensure that no electrolyte escapes.
2.3.2 Operation
Checks before operation
 Wear seat belt.
 Check the driving controls, the steering, the brake system,
and the work equipment control system.
 Check for any abnormality in the sound of the machine, vibra-
tion, heat, smell, and check the gauges. Check that there is
no leakage of oil or fuel.
 If any abnormality is found, carry out repairs immediately.
Precautions when travelling in forward or reverse
 Before travelling, check again that there is no one in the sur-
rounding area, and that there are no obstacles blocking the
machine.
 Before travelling, sound the horn to warn people in the area.
 Always sit in the operator's seat when operating the machine.
 Do not allow anyone apart from the operator to ride on the
machine.
 Check that the back-up alarm (alarm buzzer when machine
travels in reverse) works properly.
 Always lock the door and windows of the operator's cab in
position (open or closed).
 When travelling or carrying out operations, always keep a
safe distance from people, structures, or other machines to
avoid coming into contact with them.
