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.
