Hot Coolant and Oils - Burn Prevention
Do not touch any part of an operating engine. Immediately after
operations are stopped, coolant, engine oil, and hydraulic oil are
at their highest temperatures. The radiator and hydraulic tank
are still under pressure. Always wait for temperature to cool
down. Attempting to remove caps, drain oil or coolant, or
replacing filters may lead to serious burns, if done when hot.
Relieve all pressure in air system, hydraulic oil system,
lubrication system, fuel system, and cooling system, before any
lines, fittings or related items are disconnected.
To prevent hot oil or coolant from spraying out, stop engine and
wait for oil and coolant to cool. Using gloves, slowly loosen cap
to relieve pressure.
Fire and Explosion Prevention
All fuels, most lubricants and some coolant mixtures are
flammable and can cause a fire resulting in death or serious
injury, and property damage. Flammable fluids that are leaking
or spilled onto hot surfaces or onto electrical components can
cause fire.
Inspect for and remove all flammable materials such as spilled
fuel and oil, and debris from machine. Do not allow any
flammable materials to accumulate on machine.
Always observe the following:
•
Add fuel, oil, antifreeze and hydraulic fluid to machine
only in a well ventilated area. Machine must be
parked with controls, lights and switches turned
"OFF." Engine must be "OFF" and any flames,
glowing embers, auxiliary heating units or spark
causing equipment must be extinguished, or turned
"OFF" and kept well clear of machine.
•
Dust that is generated from repairing or grinding
nonmetallic hoods or nonmetallic fenders can be
toxic, flammable
components in a well ventilated area away from
flames or sparks and wear a dust mask when
grinding painted parts.
