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.
NEVER start the engine if there is any indication that
maintenance or service work is in progress, or if a warning tag is
attached to controls in the cabin.
A machine that has not been used recently, or is being operated
in extremely cold temperatures, could require a warm-up or
maintenance service before start-up.
Check gauges and monitor displays for normal operation before
starting the engine. Listen for unusual noises and remain alert for
other potentially hazardous conditions at the start of the work cycle.
Do not short circuit the starting motor to start the engine. This is
not only dangerous, but may also damage the machine.
When starting the engine, sound the horn as an alert.
Start and operate the machine only while seated.
