Protect Ears From Noise; Wear Ear Plugs; Be Careful Of Burns; Do Not Touch The Engine During Or Immediately After Operation - Mitsubishi S4S-DT Operation & Maintenance Manual

Chapter 1 BASIC SAFETY PRECAUTIONS

Protect ears from noise

Wear ear plugs

Always wear ear plugs when entering
the machine room (engine room).
Combustion sound and mechanical
noise generated by the engine can
cause hearing problems.

Be careful of burns

Do not touch the engine during
or immediately after operation
To avoid burns, do not touch the
engine during or immediately after
operation.
A hot engine can cause burns.
To conduct maintenance and inspec-
tion work, wait until the engine has cooled sufficiently
by checking the temperature gauge.
Do not open the radiator filler
cap when the engine is hot
Never open the radiator filler cap while the engine is
running or immediately after the engine is stopped.
When opening the cap, stop the engine and allow the
coolant temperature to lower sufficiently.
When opening the radiator filler cap, open slowly to
discharge the pressure inside the tank. Also to avoid a
risk of getting scalded by steam, wear thick rubber
gloves or wrap a cloth around the cap.
When closing the cap, be sure to tighten securely.
The coolant is hot while engine is running and immedi-
ately after the engine stops. If the cap is opened when
the coolant is at operating temperature, steam and hot
coolant may blow out and result in burns.
Do not touch high pressure
injection fuel
If fuel leaks or sprays out from the high pressure injec-
tion pipe, do not touch the fuel.
Fuel in the fuel injection pipes is under high pressure
and if the fuel contact your skin, it goes into deep tis-
sues and may result gangrene.
Refill coolant only after the
coolant temperature dropped
When refilling of coolant, perform it after coolant tem-
perature drops, not immediately after the engine is
stopped. Otherwise you are scalded with hot coolant.
