AIR CLEANERS WITH VACUATOR VALVE
On vacuator valve equipped models, (see figure 3)
dust cup service is cut to a minimum. A quick check
to see that the vacuator valve is not inverted,
damaged, or plugged is all that is necessary.

CHECKING AIR CLEANER RESTRICTION
Check the Air Cleaner Restriction Indicator daily for restriction. Restriction is caused by dust and dirt
accumulating on the Air Cleaner Element. The method used to check the restriction will depend upon the type of Air
Cleaner on the machine.
AIR CLEANERS WITH RESTRICTION INDICATORS
These air cleaners have a restriction indicator mounted to the Air
Cleaner body (see Figure 4). The indicator plunger will be in the
green zone when the Air Cleaner is empty - and will move up
towardsthe red zone when the Air Cleaner is full of dust and dirt.
When in the red zone, this means the AirCleaner element needs
to be replaced. See Replacing The Air Cleaner Element later
on.
Figure 4
AIR CLEANERS WITHOUT RESTRICTION INDICATORS:
Measure the restriction of the Air Cleaner with a service gauge, or a water manometer at the restriction tap provided in
the Air Cleaner, the transfer pipe, or the blower intake. Replace the element only when the restriction has reached the
maximum allowed by the engine manufacturer. Contact the Barko Service Department for maximum values and any
other questions concerning this method.
CAUTION
Check the Air Cleaner Assembly daily for cracks,
loose clamps, or any other damage. If debris is able
to bypass the Air Cleaner for any reason, it can
damage the engine.
REPLACING THE AIR CLEANER ELEMENT
For minimum vehicle downtime, replace dirty air cleaner element with a new element. DO NOT TRY TO CLEAN THE
ELEMENT! Do not leave air cleaner open to the environment longer than it takes to remove element, inspect and
clean inside of air cleaner body, and install a new element.
When restriction indicates that element servicing is required, see the replacement steps on the next page.
SAFETY ELEMENT SERVICE (IF APPLICABLE)
The safety element is not intended to be cleaned.
For maximum engine protection and air cleaner service life, replace the safety element with a new safety element
every third primary element change.
