Wheel Loader Safety
High-pressure oil that is released can cause a hose to whip or oil
to spray. Fluid penetration can result in death or serious injury. If
fluid enters skin or eyes, get immediate medical attention from a
physician familiar with this injury.
Obey all local laws and regulations for disposal of liquids.
To prevent hot coolant from spraying out, stop engine and wait
for coolant to cool. Using gloves, slowly loosen cap to relieve
pressure.
Flying or Falling Objects
On work sites where there is a potential hazard that flying or
falling objects can come in contact with operator's cabin, select
and use a guard to match operating conditions for additional
operator protection.
Working in mines, tunnels, deep pits, and loose or wet surfaces,
can produce hazard of falling rocks or flying objects. Additional
protection for operator's cabin may be required such as a Falling
Object Protective Structure (FOPS) or window guards. Contact
your DOOSAN distributor for information on available protective
guards.
To prevent personnel from being struck by flying objects, keep
personnel out of work area.
Personal Protective Equipment (PPE)
Do not wear loose clothing and accessories. Secure long hair.
These items can snag on controls or on other parts of equipment.
Do not wear oily clothes. They are highly flammable.
Do not forget that some risks to your health may not be
immediately apparent. Exhaust gases and noise pollution may not
be visible, but these hazards can cause disabling or permanent
injuries. Breathing masks and/or ear protection may be required.
Wear a hard hat, safety shoes, safety goggles, mask, leather
gloves, earplugs and other protective equipment, as required.
While working on machine, never use inadequate tools. They
