VACUUMING DRY MATERIALS
1. The Filter must always be correctly installed to
avoid leaks and possible Vac damage.
2. To maintain peak performance when vacuuming
fine dust, clean the Drum and Filter regularly.
NOTE: Do not use a wet Filter when picking up dry
material. The Filter will quickly clog and be difficult to clean.
3. If the Filter is wet, you must allow it to dry
completely or replace it with a dry Filter before
using the Vac to pick up dry material.
VACUUMING LIQUIDS
1. Vacuuming up small amounts of liquid (less than
2" (5 cm) collected in Dust Drum) does not require
Filter removal.
2. When larger amounts of liquid are to be picked up,
remove all dry use only Paper Filter(s) and replace
with a RIDGID wet application Foam Filter. Do Not
remove the Filter Cage or Float. The Foam Filter is
specifically designed for high volume liquid pick up.
If the paper Filter is used and becomes saturated,
you may see "mist" coming from the Blowing Port.
3. When the Drum is "full" the Float will rise and cut
off airflow. The motor sound will rise in pitch and
its speed will increase indicating the Drum is "full".
Turn OFF the Vac and unplug the power cord before
emptying the Drum.
