TEMPERATURE OF WATER AND OIL
It is dangerous to drain hot oil or water or replace filters immediately after the engine is stopped. Wait
for them to cool down. On the other hand, if oil is cold, warm it for about 5 minutes to about 20 to 40
degrees C (68 to 104 degrees F) with low idling before draining it.
USE OUR GENUINE PARTS
・
For replacement of parts, grease and oil, be sure to use our genuine parts.
Use grease and oil with the specified viscosity depending on the ambient temperature.
・
Store containers for grease and oil in a clean room to keep them away from dust and water.
BE CAREFUL WITH INNER PRESSURE
Release the inner pressure before removing the piping, coupling or other parts of the hydraulic system,
air system, fuel system or cooling system to which inner pressure is applied.
For removing the inner pressure of the hydraulic oil tank, see "CHECKING HYDRAULIC OIL LEVEL
AND MAKING UP" in Chapter 3.
KEEP OUT DUST
Attach a plug or cap to the lubrication hole of a removed hydraulic hose or hydraulic component to
keep out foreign materials.
INSPECT DRAIN OIL AND FILTERS
When replacing oil or filter, check the drain oil or old filter for metallic powder or other foreign materials
mixed. Contact the person in charge and take appropriate measures if any foreign materials are found.
HANDLING OF WASTE OIL AND ANTIFREEZE
Be sure to drain waste oil and antifreeze in containers and ask a public service company for disposal
of them as the industrial waste.
CLEAN THE SEALING SURFACE
After removing the O-ring or gasket seal, clean the sealing surface to replace it with a new one.
Apply thin oil to the O-ring or seal to attach it into the groove.
DO NOT MIX OILS
Never mix different kinds of oil. When using another kind of oil, replace the total amount of old oil.
LOCK THE INSPECTION DOOR
When performing the maintenance with the inspection door open, be sure to lock the door. Sudden
door close by a blast, etc. may cause injury if the door is left open and unlocked during the
maintenance.
CLEANING AND REPLACING THE RADIATOR CAP
・
The radiator cap is an important part which pressurizes coolant to avoid overheat.
・
Remove any dirt or water scale adhered on the gasket surface.
・
It is not capable of pressurizing due to steam leakage if an aged groove on the gasket surface is
created. Replace it with a new one.
・
Replacing it every year is a guideline.
PRECAUTIONS IN REFILLING
Do not remove the strainer at refill if it is fitted to the filler port.
