EVACUATOR VALVE
Open the evacuator valve once a week
under ordinary conditions - or daily when
used in a dusty place - to get rid of large
particles of dust and dirt.
IMPORTANT
The air cleaner uses a dry ele-
ment, never apply oil.
Do not run the engine with filter
element removed.
Be sure to refit the cover with the
arrow
(on the rear of cover)
upright. If the cover is improp-
erly fitted, evacuator valve will not
function and dust will adhere to
the element.
Do not touch the secondary ele-
ment except in cases where re-
placing is required.

ondary Element” in Every 1 Year

CLEANING AIR CLEANER PRIMARY
ELEMENT

1. The air cleaner uses a dry element.
Never apply oil.
2. Do not let dust build up to more than a
half of the dust cup. Detach the dust
cap and clean out the dust and clean
the element normally once a week. But
everyday check if working conditions
are especially dusty.
CLEANING AIR FILTER ELEMENT
To clean the element, use only clean dry
compressed air on the inside of the
element. Air pressure at the nozzle must
not exceed 29 psi (2 kgf/cm²). Maintain
reasonable distance between the nozzle
and the filter.
IMPORTANT
The air cleaner will only fulfill its
function if it is correctly and regu-
larly maintained. A poorly main-
tained air cleaner will mean loss
of power, excessive fuel con-
sumption and a reduction in en-
gine life.
3. Do not touch the filter element except
in cases where cleaning is required.
4. When cleaning the element, refer to
the instructions that follow.
5. If the element is stained with carbon
or oil, replace the filter.
6. Change the element every 6 months
or every 100 hours.
