Safety
areas. If the ground should collapse, the machine could fall or tip
over and this could result in serious injury or death.
Remember that the soil after heavy rain, blasting or after
earthquakes, is weakened in these areas.
Earth laid on the ground and the soil near ditches is loose. It can
collapse under the weight of vibration of your machine and
cause your machine to tip over.
Install the head guard (FOPS) if working in areas where there is
danger of falling rocks.
Checks Before Starting Engine
Every day before starting the engine for the first time, carry out
the following checks. If these checks are not carried out
properly, there is danger of serious injury.
Completely remove all wood chips, leaves, grass, paper and
other flammable materials accumulated in the engine
compartment and around the battery. They could cause a fire.
Remove any dirt from the window glass, mirrors, handrails, and
steps.
Do not leave tools or spare parts laying around in the operator's
compartment. The vibration of the machine when traveling or
during operations may cause them to fall and damage or break
the control levers or switches. They may also get caught in the
gap of the control levers and cause the work equipment to
malfunction or move dangerously. This may lead to unexpected
accidents.
Check the coolant level, fuel level, and hydraulic tank oil level,
and check for clogged air cleaner and damage to the electrical
wiring.
Adjust the operator's seat to a position where it is easy to
operate the machine, and check the seat belt and mounts for
damage and wear.
Check the operation of the gauges and the angle of the mirrors,
and check that the safety lever is in "LOCKED" position.
If any abnormalities are found in the above checks, carry out
repairs immediately.
Engine Starting
Walk around your machine before getting in the operator's
cabin. Look for evidence of leaking fluid, loose fasteners,
misaligned assemblies or any other indications of possible
equipment hazard.
All equipment covers and machinery safety guards must be in
place, to protect against injury while the machine is being
operated.
Look around the work site area for potential hazards, people or
properly that could be at risk while operation is in progress.
