'Measuring Air Restriction'.
Safety element (3) is installed in each air cleaner
assembly inside of primary element (2). This element
increases the reliability of the air cleaner’s protection
of the engine from airborne dirt. It protects the engine
from dirt admitted by a damaged primary element (2),
or dirt that might be dropped into the air cleaner
assembly while servicing primary element (2).
MAINTENANCE
Numbers in parentheses refer to Fig. 1, unless
otherwise specified.
WARNING
Always shutdown the engine before servicing
air cleaner.
The air cleaner elements should be serviced only
when the maximum allowable restriction has been
reached, as indicated by air cleaner restriction
indicator light. The elements should not be serviced on
the basis of visual observation as this would lead to
over service. When restriction readings finally indicate
a change, remove primary element (2) carefully and
clean/replace as required. Refer to 'Primary Element'.
Never attempt to clean safety element (3). Change
safety element (3) after every third primary element (2)
service.
Make sure vacuator valve (6) is not damaged or
plugged and that the joint with cover assembly (4) is
not broken. If vacuator valve (6) is lost or damaged,
replace it to maintain pre-cleaner efficiency and normal
filter element service life.
Check condition of clamps (9 & 10, Fig. 3), hump
hoses (6 & 7, Fig. 3), elbows (8 & 15, Fig. 3), tube
assembly (1, Fig. 3) and tube (2, Fig. 3). Tighten/
replace as necessary.
