MAINTENANCE
The amount of air filter operation has a direct bearing on
when you must clean or replace the filters.
To maintain efficient operation, check the filters
approximately every 40 hours of use in light or moderately
dusty environments. In very dusty environments, check
the filters every eight hours of use. Always wear a
respirator when checking the filters.
To.change.and.service.the.filters,.do.these.steps:
1. DISCONNECT MACHINE FROM POWER!
2. Un-latch the filter retaining clips from the top and
bottom of the unit, as shown in Figure.13, and
remove the outer filter. Place the filter in a trash
bag and shake it gently to remove the bulk of the
dust.
If you choose to use compressed air to further clean
the filter, do so outdoors and in an appropriate
environment where people are not in the immediate
vicinity.
3. Remove the inner filter, place it inside a trash bag
and gently shake the dust from the inside of the
filter.
Optional: Wash the inner filter with water to remove
the remaining dust, then let it air dry completely.
4. Re-install the inner filter, then re-install the outer
filter with the wire mesh facing to the inside.
5. Re-latch the retaining clips to secure the filters.
Note: During regular use the filters can be cleaned
several times before replacement becomes necessary. To
determine whether the filters need to be replaced, hold
them up to the sunlight and visually inspect them. If you
cannot see through the filters due to caked dust and
grim, replace them before putting air filter back into
operation.
