Sign off on the 50 Hourly Bulldozer Maintenance

WARNING: The engine is at high temperature immediately after the machine has been operated. Wait for the engine to cool down before replacing the filter. Do not bring fire or sparks near the fuel.

Prepare a filter wrench and a container to catch the fuel.

Set the container under the filter cartridge to catch the drained oil.

Using a filter wrench, turn filter cartridge (1) counterclockwise to remove it.

Clean the filter holder, fill the new filter cartridge with clean fuel, then coat the packing surface with oil and install to the filter holder.

NOTICE: When filling with fuel, use clean fuel and be careful not to let any dust or dirt get in. Portion (B) at the center is the clean side, so be particularly careful not to let any dust or dirt get in. When adding fuel, always add from small hole (A) at eight places on the dirty side.

When installing, tighten until the packing surface contacts the seal surface of the filter holder, then tighten it up 1/2 to 3/4 of a turn.

If the filter cartridge is tightened too far, the packing will be damaged and this will lead to leakage of fuel. If the filter cartridge is too loose, fuel will also leak from the packing, so always tighten to the correct amount.

Loosen the knob of feed pump (2) and operate it 50 to 60 times up and down. This will bleed the air.

CHECK, CLEAN AND REPLACE AIR CLEANER ELEMENT

If inspection, cleaning, or maintenance is carried out with the engine running, dirt will get into the engine and damage it.

Always stop the engine before carrying out these operations.

When using compressed air, there is danger that dirt may be blown around and cause serious injury.

Always use protective glasses, dust mask, and other protective equipment.

Whenever the red piston in dust indicator (1) appears, clean the air cleaner element.
