INSPECTION AND ADJUSTMENT
1. INSPECTION AND ADJUSTMENT
1-1. Safety Precautions for Inspection and Adjustment
WARNING
Unexpected machine movement may cause a serious accident. When inspecting the machine while the
engine is running, always follow the instructions below.
• Park the machine on level, fl at ground.
• Apply the parking brake.
• Set chocks in front and behind each drum or tire.
• Make sure that service personnel are given the appropriate information at the appropriate time.
• Make sure that no one can enter any hazardous area.
CAUTION
Do not work on the hydraulic system while the engine is running and the system is hot and under
pressure. Do not disconnect hydraulic hoses or
fi ttings until the system has cooled and pressure has
been properly relieved.
Before removing any plugs from the pressure measurement ports, always release any residual pressure
from the piping and open the cap of the
fl uid tank to release and pressure.
WARNING
Inadvertent starting the engine may cause a serious accident.
When inspecting the engine, make sure to exchange the appropriate cues and hand signal with the person
at the operator station to avoid any accidents.
CAUTION
Before inspecting inside of the engine compartment, always stop the engine.
Contact with the fan, V-belt or exhaust system parts while the engine is running may cause serious injury.
1-2. Preparation for Inspection and Adjustment
• Prepare the necessary measuring instruments. In addition, particularly when measuring pressure values, make
sure to prepare the appropriate hoses, adapters and a plug removal tool for the pressure reading port.
• Make sure that the instruments to be used operate normally.
When handling the instruments, exercise suf fi cient caution not to drop or apply any impact to them. Doing
so may adversely affect the calibration. Another important point is to inspect the instruments regularly. An
instrument that does not start from the appropriate zero point may give an inaccurate reading.
1-3. Precautions for Inspection and Adjustment
• When performing inspections and adjustments, pay special attention to safety.
• For each inspection, always take three measurements for each measurement point. If the measurements
signi fi cantly differ, the measurement method may be incorrect. In such a case, take measurements once again
and calculate their average.
1-4. Warm-up
• Machinery will not exhibit their true performance under the cold condition. Before taking measurements, always
warm up the engine and make sure that the fl uid and engine coolant are warmed to their speci fi ed normal
operating temperatures.
1-5. Inspection and Adjustment of Engine Related Items
• Refer to shop manual of engine manufacturer for inspection and adjustment of engine itself.
