4.15DAILY INSPECTION AND

MAINTENANCE

Thoroughly read and understand the section, “SAFETY PRECAUTIONS” of this MANUAL before operating or servicing the machine. The following inspection and maintenance shall be carried out before starting / after starting and after work.

REFER TO SECTION “BASIC MACHINE OPERATION” IN THE FOLLOWING ITEMS FOR INSPECTION AND MAINTENANCE:

• Check Coolant Level •Check Coolant Leakage •Check Fuel Level •Check Fuel Leakage •Check Belt •Check Hydraulic Oil Level •Check Engine Oil Level •Check Warning Lamps •Check Working Light •Check Exhaust Gas Color, Abnormal Sound and

Smell •Check each Switch and Lever

A.CHECK EXTERNAL CONDITIONS OF

MACHINE

A dent or distortion which apparently seems not to be severe damage, may be abnormal contact on internal parts or hoses.

Consult with your Dealer for advise and/or for repairs.

B.CHECK CAPSCREWS AND NUTS FOR

LOOSENESS AND/OR MISSING

Check for missing capscrews and nuts and replace as needed. Check and make sure all capscrews and nuts are properly tighten.

Likewise, check and make sure all hose clamps are properly tighten.

The abnormal sound during operation may cause leakage or fire. Use torque values.

NOTE: Use the tools suitable for the work referring to Section IV “ TOOLS”.

C.CHECK EACH CYLINDER, PIPING AND HOSE FOR LEAKAGES AND DAMAGES

WARNING

Hydraulic line is always highly pressurized. Make sure to release the pressure in the line before starting service and/or maintenance, or refilling. Never use hands to check for leaks. High pressure fluid leaks will penetrate the skin and cause severe injury.

WARNING

Be cautious of hot fluids and surfaces, wear goggles, safety shoes, hard hat, work clothes, and work gloves to perform inspection and maintenance on this machine.

Hydraulic oil leakage will slow down a machine. Move the machine to firm level ground and place the attachment in the oil check position and stop the engine. 1.Set the safety lock lever to “LOCKED” position, then stop the engine. 2.To check the location of leakage, take a time to allow getting the temperature on each portion of the machine down to around 40˚C(104˚F). Make sure to wear the protective glasses and gloves for the check. 3.Press the rubber cap of the air breather on the top of the hydraulic oil tank several (five to seven) times to release the internal pressure of the tank.

NOTE: When any abnormalities happen on the machine, immediately stop operation, and ask for repairs as needed. When the volume becomes insufficient for the engine coolant or oil due to leakage, an warning lamp is illuminated.

D.CHECK TRAVEL SYSTEM FOR LEAKAGE

AND ABRASION

1.Check the lower roller, idler and travel motor for any leakages. 2.Check the lower roller, idler, and sprocket for abnormal wear and loosened fixing bolts. 3.Slowly travel the machine and check for any abnormal sound.

NOTE: Consult with your Dealer for advise and/or repairs as needed.
