Conduct Proper Maintenance Of Air Cleaner - Mitsubishi S 12 R User And Maintenance Manual

Conduct proper maintenance of
air cleaner
The major cause of abnormal wear on engine parts
is dust entering with intake air. Worn parts result in
an increase of oil consumption, decrease of output,
and starting difficulties. Conduct maintenance of
the air cleaner according to the following directions
to ensure optimum air filtering performance.
• Do not conduct maintenance of the air cleaner
while the engine is operating.
Without the air cleaner in place, the turbocharger
can suck foreign particles into the engine,
decrease the load immediately so that the engine
operates at appropriate output and load.
• When removing the air cleaner, do not allow dust
attached on the air cleaner to enter into the
engine.
• If equipped with a dust indicator, conduct mainte-
nance only when the clog warning sign appears.
While servicing the air cleaer, do not let dust
enter into the air cleaner, damage or deform the
element.
Observe safety rules at workplace
Observe the safety rules established at your work-
place when operating and maintaining the engine.
Do not operate the engine if you are feeling ill.
Operation of the engine with reduced awareness
may cause accidental operations that may result in
accidents. In such case, you should inform your
supervisor of your condition.
When working in a team of two or more persons,
use specified hand signals to communicate among
the workers.
Wear proper work clothes and
protective gear
Wear the work clothes specified by your workplace.
Wear a hardhat, face shield, safety shoes, dust pro-
tective mask, gloves and other protective gear as
needed.
When handling compressed air, wear safety gog-
gles, hardhat, gloves and other necessary protec-
tive gear. Compressed air may cause personal
injury when not wearing the proper protective gear.
Chapter 1
BASIC SAFETY PRECAUTIONS
Use appropriate tools for mainte-
nance work
Use appropriate tools according to the type of
maintenance work, and use them correctly.
If tools are damaged, replace with new tools.
Do not operate starter for pro-
longed time
Do not use the starter for more than 10 seconds at
a time. If the engine does not start, wait for at least
30 seconds before cranking again.
Continuous operation of the starter will cause drain-
ing of the battery as well as the starter to seize.
Do not turn off battery switch
while engine is operating
Do not turn off the battery switch while the engine is
in operation.
Turning off the battery switch while the engine is in
operation not only stops the instrument operations
but also damages the electronic devices on the
secondary side.
Cautions concerning transporta-
tion
When transporting the engine using a truck, con-
sider the engine weight, width and height to ensure
safety. Abide by the pertinent laws and regulations.
