ecause flter elements For the Scraper cab’s air system are located on the rooF they
sometimes don’t get regular cleaning.
The fltering elements can
keep you supplied with clean
air, regardless oF how dusty
work sites can be. But, iF you
want clean air circulating in
your cab, you’ve got to keep the
flter elements clean.
BeFore you start using low-
pressure air (30 psi or less) to
clean the elements, make sure
that leaves, dirt, ice or snow
aren’t blocking the air inlets.
To help keep elements clean,
start your day’s run by removing
the elements and tapping them
with your hand to loosen and
dislodge trapped dirt.
Don’t bang elements against
the cab or other hard surFaces!
That would bend sealing edges
or crush its fltering material.
Then you’d really be hitting the
dusty trail.

eeping a multipurpose tool around when doing maintenance really helps.
If you need a stainless steel pocket tool with just a knife and pliers, order one with NSN
5110-01-346-5339, or order the flat black version with NSN 5110-01-346-5341.
Carry the multipurpose tool in a pocket or, if authorized, wear it on your belt using the
black sheath that comes with it. Appendix A of CTA 50-970 is your authority for ordering.
Remember, though, while it may be OK to use a multipurpose tool during maintenance,
don’t use it for critical repairs. Always use the correct tool to complete a maintenance task
like your IETM/manual says.
