GENERAL PRECAUTIONS
Some recommended and standard maintenance services for your engine are included in this section. When performing main-
tenance on your engine, be careful not to get injured by using improper work procedures. Improper or incomplete work can
cause a malfunction of the engine, which may result in personal injury and/or property damage. If you have any questions
about performing maintenance, please consult your Hino dealer.
When working on your engine, observe the following general precautions to prevent death, personal injury and/or
property damage, in addition to the particular DANGERS, WARNINGS, CAUTIONS and NOTICE in each chapter.
•
Always wear safety glasses or goggles to protect your eyes.
•
Remove rings, watches, ties, loose hanging jewelry and loose clothing before starting work on the vehicle.
•
Bind long hair securely behind the head.
•
When working on the vehicle, apply the parking brake firmly, place the gear shift lever in "Neutral" or "N" and
block the wheels.
•
Always stop the engine and turn off the starter switch, unless the operation requires the engine running.
Removing the key from the switch is recommended.
•
To avoid serious burns, keep yourself away from hot metal parts such as the engine, exhaust manifold, radia-
tor, muffler, exhaust pipe and tail pipe.
•
Do not smoke while working on the vehicle, since fuel and gas from battery are flammable.
•
Take utmost care when working on the battery. It contains corrosive sulfuric acid.
•
Large electric current flows through the battery cable and starter cable. Be careful not to cause a short, which
can result in personal injury and/or property damage.
•
Read carefully and observe the instructions placed on the jack before using it.
•
Use safety stands to support the vehicle whenever you need to work under it. It is dangerous to work under a
vehicle supported only by a jack.
•
If it is necessary to run the engine after the hood is raised (tilted), make sure that the parking brake is firmly
applied, the wheels are blocked, and the gear shift lever is positioned in "Neutral" before staring the engine.
•
Run the engine only in a well-ventilated area to avoid inhaling of carbon monoxide.
•
Keep yourself, your clothing and your tools away from moving parts such as the cooling fan and V-belt when
the engine is running.
•
Be careful not to damage lines and hoses by stepping or holding on them.
•
Be careful not to leave any tool in the engine compartment. Tools may be hit by moving parts, which can cause
personal injury.
