MAINTENANCE

Lubrication

All bearings are sealed and permanently lubricated, no
lubrication is required.
Make a habit of inspecting your dust collector each time
you use it to ensure optimum performance.
Check for the following conditions and repair or
replace when necessary:
• Worn or damaged switch, switch-safety key, electri-
cal cords and plugs.
• Loose mounting bolts, loud rubbing, vibration or
tapping noises coming from motor or impeller hous-
ing.
• Clogged, frayed, or leaking dust collection bags.
• Any other condition that can cause an unsafe condi-
tion.

General

Emptying the collector bag exposes
you to harmful dust. Always wear a
respirator and safety goggles when
emptying the collector bag!

Emptying Collected Dust

The lower bag on the dust collector should be emptied
when it becomes 2⁄3 to 3⁄4 full.
1. ALWAYS WEAR A RESPIRATOR WHEN EMPTYING
DUST COLLECTION BAGS (see Figure 26).
2. Shake the upper bag and let the dust inside settle
for a few minutes.
3. Loosen the latch clamp holding the bag.
4. Take the bag off of the collector body and close up
the opening.
5. Place a garbage bag over the opening of the collec-
tion bag. Invert both bags to empty.
6. Clean or reinstall the bag on the dust collector.
Figure 26. Wearing a respirator and safe-
ty goggles for personal dust protection.
The lower dust storage bag is intended to be cleaned by
simply emptying it. Once a year under heavy use, hand
wash in cold water with a mild soap, and hang dry only.
DO NOT wash bags in a laundry machine or tumble dry.
