3. INSPECTION OF EACH PART

1) Inspection of the cleaner body

(1) Check the cleaner exterior for cracks, deformation,or damage and repair or replace if necessary.

(2) Check each packing for fatigue or damage and replace if necessary.

Note:

Especially note the glue portions of the paper and metal parts.

4. CLEANING THE AIR CLEANER

Clean the air cleaner after 100 hours of operation or less depending on conditions in the following manner.

1) When the air cleaner is cleaned or the element is replaced,dust accumulated inside the air cleaner body should be removed with a cloth.As inhaled dust causes engine wear,remove a dust accumulated inside the inlet pipe,the rubber hose which connects in the inlet pipe and the air cleaner,the inlet manifold,and inlet port.

(1)When accumulated dust is dry.

-When removing the dust in the element,hold the element by a hand and pat the side wall with other hand.Never hit the element against a stone or a concrete wall because that might cause its side wall to peel off.

2) Inspection of rubber hoses

Check the rubber hoses for fatigue or damage and replace if necessary.

3) Inspection of the paper element

To check the element for damage,Dry it sufficiently after washing and put an electric bulb in to the element and look for damage.

-apply compressed air from inside of the element to blow dust off while turning the element by hand.

Note:

The compressed air to be applied should not have a pressure of more than 7㎏/㎠(99.6psi) Maintain sufficient distance between the air gun and the element.

(2)When accumulated dust is oily.

-Use a solution of TC 101 element detergent or the quality household neutral detergent. Leave the element in the solution for approximately 30 minutes and then wash it by dipping it in and out of the solution.

-After soaking,rise it in fresh water.

-Let it in a shaded and well ventilated place. Forced drying by heat or compressed air is prohibited.

Note:

Water applied to rinse the element should not have a pressure of more than 2.8kgf/㎠ (39.8psi).

An element which has been washed 5 times must be replaced with a new one.

5.ELEMENT INSTALLATION

Install the element in the reverse order of disassembly,but follow these instructions.

1) Each tightening bolt must be secured and care must be taken not to miss the packing and washers.

2) Before installing the element,clean the rubber packing on the top of the element.

Note:

The wing bolt retaining the element should be tightened sufficiently so that it will not become loose during operation
