Maintenance

How To Replace The Filter Bag

Any other servicing should be done by an authorized service representative.

If appliance is not working as it should, has been dropped, damaged, left outdoors, or dropped into
water, take it to a service center prior to continuing use.

THERMAL PROTECTOR STATEMENT

A thermal protector has been designed into your cleaner to protect it from overheating.
When the thermal protector activates the cleaner it will stop running.
If this happens proceed as follows:

1. Turn cleaner OFF and remove battery pack.

2. Check fullness of bag, change if needed.

3. Inspect the air path for any obstructions. Clear obstructions if present.

4. When battery pack is removed and motor cools for 30 minutes, the thermal protector will
deactivate and cleaning may continue.

If the thermal protector continues to activate after following the above steps, your cleaner
needs servicing.

WARNING

NOTE: When using the vacuum to pick up very fine dust, such as sawdust or drywall dust, it will be
necessary to replace the bag and clean the filters at more frequent intervals to maintain maximum
suction. Fine dust will clog bag pores and reduce suction, prior to bag becoming full.
