If the machine is slow or stops flushing, but the motor
and air still operate, please follow these procedures.
Clean the filter(s): Cleaning the filters should be
done as a normal part of machine maintenance to
prevent problems from occurring.
1. Locate the external filter at the end of the black
service hose where it attaches to the machine.
Figure 1-3
2. Unscrew the cup portion from the filter housing.
3. This filter screen can be cleaned with tap water
and then blown out with compressed air. The screen
is permanently glued to the cup section of the filter
housing; do not attempt to remove it.
4. Replace the cup taking care not to pinch the
gasket.
Some of the older machines may also have an internal
filter (Figure 1-4) that can be cleaned or removed
(current production machines do not use an internal
filter).
To access and clean the internal filter:
1. Remove the rear bottom service panel behind the
machine and see if there is a filter attached to the
pump. It may be either a silver Y shaped filter, or a
black canister type. The silver version can be
opened and the screen cleaned; the black one may
be back flushed in the direction opposite the flow
arrow.
2. Clean either type with water or cleaner solvent
and blow out with compressed air.
