Clean the bag regularly, preferably daily.
Dry-Collector bag dry cleaning
• The dry collecting bag can be brushed or tapped. Allow
the unit to run in idle gas.
Warning:
Do not breathe
in the dust generated, protect yourself with suitable
respiratory protection.
Dry-Collector bag wet cleaning
• Leave the safety bag on the machine and start the
engine. Now the bag inflates.
• Open the zipper by approx. 15 cm.
• Now you can comfortably spray the bag from the inside
out with the lance of a high-pressure cleaner or with a
hose.
• If you allow the engine to run for a short time after
splashing the bag, it will dry quickly.
You can also clean the collection bag in a water bath or
have it cleaned in a commercial cleaning machine. Rub
the zipper with talcum after cleaning to ensure a perfect
function.
