INSPECTION
The valve clearance specification is different for intake and
exhaust valves. Valve clearance adjustment must be checked
and adjusted, 1) at the time of periodic inspection, 2) when the
valve mechanism is serviced, and 3) when the camshaft is dis-
turbed by removing it for servicing.
Be sure to position the element snugly and correctly,
so that no incoming air will by-pass it. Remember, the
rapid wear of piston rings and the cylinder bore is
often caused by a defective or poorly fitted element.
If driving under dusty conditions, clean the air cleaner
element more frequently. The surest way to accelerate
engine wear is to operate the engine without the ele-
ment or to use a torn element. Make sure that the air
cleaner is in good condition at all times. The life of the
engine depends largely on this component!
Inspect initially at 1 month and every 6 months there-
after.
