AIR CLEANER MAINTENANCE
Proper air cleaner servicing will result in maximum engine protection against the ravages of dust. Proper servicing
can also save you time and money by increasing filter life and dust cleaning efficiency. Two of the most common
servicing problems are:
1. Over-servicing: New filter elements increase in dust cleaning efficiency as dust builds up on the media.
DON'T BE FOOLED by filter appearance, it should look dirty. By using proper filter restriction measurement
tools you will use the full life of the filter at maximum efficiency.
2. Improper Servicing: Your engine is highly vulnerable to abrasive dust contaminants during the servicing process.
THE MOST COMMON CAUSE OF ENGINE DAMAGE IS DUE TO CARELESS SERVICE PROCEDURES. By
following the steps shown below and on the next few pages, you can avoid unnecessary dust contamination
to the engine.
The following steps should be taken on a daily basis or more often in severe conditions:
1. Check to ensure that the air cleaner bonnet is free of leaves, twigs, etc. that are drawn in while the machine is
working. (See Figure 1).
NOTE: This is especially important in the fall months, as the trees shed their leaves.
2. Empty the pre-cleaner dust cup. Frequency of dust cup service will vary with dust conditions. See Emptying The
Dust Cup.
3. Check the restriction indicator daily. When indicated, change the element. See Checking Air Cleaner Restriction.
EMPTYING THE DUST CUP
Check the dust cup daily for dust build-up. When reinstalling the dust cup, make sure it seals 360 degrees around the
air cleaner body and the directional arrows are pointed in the UP position. See Figure 2 on next page.
