BEFORE YOU OPERATE
49
DAILY CHECKS
Before you begin any job, make sure the Isuzu C
series engine is in good operating condition. Make
sure you check the following items before you start
your shift and have any repairs completed before
you start work.
WARNING
High-Pressure Hazard!
• Avoid skin contact with the
high-pressure diesel fuel spray
caused by a fuel system leak
such as a broken fuel injection
line. High-pressure fuel can
penetrate your skin and result
in serious injury. If you are
exposed to high-pressure fuel
spray, obtain prompt medical
treatment.
• Never check for a fuel leak with your hands.
Always use a piece of wood or cardboard.
Have your Isuzu Distributor repair the
damage.
• Failure to comply could result in death or
serious injury.
NOTICE
Make it a habit to perform daily checks. See Daily
Checks in the Before You Operate Section of this
manual.
Periodic maintenance prevents unexpected
downtime, reduces the number of accidents due to
poor machine performance and helps extend the
life of the engine.
Visual Checks
1. Check for engine oil leaks.
2. Check for fuel leaks.
3. Check for engine coolant leaks.
4. Check for damaged or missing parts.
5. Check for loose, missing or damaged fasteners.
6. Check the electrical harnesses for cracks,
abrasions, and damaged or corroded
connectors.
7. Check hoses for cracks, abrasions, and
damaged, loose or corroded clamps.
8. Check and clean radiator fins as necessary.
See Check and clean radiator fins on page 76.
9. Check the water separator for presence of
water and contaminants. If you find any water or
contaminants, drain the water separator. See
Drain water separator on page 71. If you have
to drain the water separator frequently, drain the
fuel tank and check for the presence of water in
your fuel supply. See Drain fuel tank on
page 75.
NOTICE
If any problem is noted during the visual check, the
necessary corrective action should be taken before
you operate the engine.
Check Diesel Fuel, Engine Oil and
Engine Coolant Levels
Follow the procedures in Diesel Fuel on page 36,
Engine Oil on page 43 and Engine Coolant on page
46 to check these levels.
Check Engine Speed Control
Check the engine speed control for smooth
operation, adjust and lubricate or clean as
necessary. See Check and adjust the governor
lever and engine speed control (except
electronically controlled engines) on page 77.
