General Precautions
Contact a Dealer of Mitsubishi

Repair Service
Repairing a malfunctioning engine may require special
equipments or involve potentially dangerous work,
except for relatively simple procedures such as the
change and addition of fuel, engine oil and coolant.
When repairing malfunctioning engine, contact a
dealer of Mitsubishi Heavy Industries, Ltd.
Considerations Before Work
Before troubleshooting, consider possible causes of
the problem and try to find out if the same problem
have occurred in the past.
Check the parts that may be causing the problem in
the most efficient order.
When disassembling a component, pay close atten-
tion to the disassembly sequence so that you can
reassemble the component in reverse order of disas-
sembly.
Cautions Against Contamina-
tion
Dust and foreign materials are the most common
cause of rapid wear of parts.
When disassembling a component, take measures to
prevent dust and foreign materials from entering the
component being disassembled.
Cautions Regarding Parts Han-
dling
Handle parts carefully.
When replacing parts, use only genuine parts by refer-
ring to the parts catalogue.
Safety Work
Be sure to use wrenches of the correct size. Using a
wrench of the wrong size can cause not only nut dam-
age but also the personal injury.
Use correct tools and perform apposite work with the
most careful attention.
Be sure to accurately estimate the weight of the part
being dismounted. If the removed part is much heavier
than you have estimated, it may fall down during lifting
and can result in the damage to the parts or personal
injury.
