Adjusting belt tracking

While the belt is running, use the adjusting knob to center the belt tracking.
Failure to do so can result in frayed belt edges and wear on the sander frame.
Dust bag

Attach the dust bag onto the dust spout. The dust spout is tapered. When
attaching the dust bag, push it onto the dust spout firmly as far as it will go to

prevent it from coming off during operation.
When the dust bag is about half full, remove the dust bag from the tool and pull

the fastener out. Empty the dust bag of its contents, tapping it lightly so as to
remove particles adhering to the insides which might hamper further collec-
tion.
NOTE:
• If you connect a Makita vacuum cleaner to this tool, more efficient and
cleaner operations can be performed.
