Cleaning the Filters
SECTION 6: MAINTENANCE
In order to maintain optimal operation, the filters
in the double air filter should be checked, cleaned
and/or replaced regularly depending on usage.
Checking the filters once a week in a small home
shop is a good habit. Checking them once a day
during heavy use is important. Always wear a
respirator when checking the filters.
To check, clean or replace the filters:
1. Disconnect power to the double air filter.
2. Lift the primary filter so it can clear the retain-
ing rim; remove and examine carefully and
replace as needed. Figure 9
3. Remove the secondary filter, place it inside a
trash bag, and gently shake the dust from the
filter.
4. The secondary filter can be washed with
water to remove the last of the dust and help
maximize its filtering effect. DO NOT use
compressed air to clean the filter as it will be
damaged and lose its filtering capabilities.
5. Be sure the secondary filter is completely dry
before installing it into the double air filter.
6. Install a new primary air filter over the sec-
ondary filter.
During regular use, the secondary filter can
be cleaned several times before it needs to be
replaced. It is important to look for holes in the
filter that would reduce the filtering effect. Please
see the current Grizzly catalog for replacement
information.
