Before performing service operations, inquire into the customer’s complaints and ascertain the conditions by
checking the total distance traveled, the conditions under which the vehicle is operated, and other relevant factors
about the vehicle. And note the necessary information. This information will help you to service the truck efficiently.
•
Check the location of the fault, and identify its cause. Based on your findings, determine whether parts must be re-
moved or disassembled. Then, follow the service procedure given in this manual.
•
Prepare all the general and special tools necessary for the job.
WARNING
• Special tools must be used wherever specified in this man-
ual. Do not attempt to use other tools since they could
cause injuries and/or truck damage.
•
Take extreme care when removing/installing heavy items such
as engine, transmission and axle. When lifting heavy items using
a cable etc., observe the following precautions.
•
Identify the weight of the item being lifted. Use a cable that is
strong enough to support the weight.
•
If lifting eyes are not provided on the item being lifted, tie a ca-
ble around the item taking into account the item’s center of
gravity.
•
Never work in shoes that have oily soles.
When working with a partner or in a group, use pre-arranged
signals and pay constant attention to safety. Be careful not to
touch switches and levers unintentionally.
•
Inspect for oil leakage etc. before washing the vehicle. If the or-
der is reversed, any oil leakage or fault that may exist could go
unnoticed during inspection.
