Fitting the HAMMERVAC™ to the Tool and Bit For proper suction and depth control, position the nozzle assembly so the bit is flush with the for- ward face of the nozzle: 1. Press and hold the tool and

bit adjustment button.

2. Push in the nozzle assem-

bly until the bit is flush with the front face of the nozzle.

3. Release the tool and bit ad- justment button.

NOTE: Fully extend the HAM- MERVAC™ before storing to preserve spring life.

WARNING Always remove battery pack before changing or removing acces- sories. Only use accessories specifically recommended for this tool. Others may be hazardous.

Inserting/Removing the Battery

To remove the battery, push in the release buttons and pull the battery pack away from the tool.

To insert the battery, slide the pack into the body of the tool. Make sure it latches securely into place.

WARNING To reduce the risk of in- jury, always remove the battery pack before removing the dust box. Do not use tool with- out dust box and HEPA filter in place.

Installing/Removing the

Dust Box and HEPA Filter

loss of suction, discard and
replace HEPA filter (Cat. No.
49-90-2306).
To install the dust box:

1.Slide the dust box into the body of the HAM- MERVAC™.

2.The dust box latch should snap into place. NOTE: Do not operate the HAMMERVAC™ with- out the dust box and HEPA filter in place. Dust box cannot be installed without HEPA filter.

CAUTION Keep filter clean. Efficiency of the HAMMERVAC™ is largely dependent on the filter. A dirty filter will reduce the air flow and overall efficiency of the system. Do not clean with water or compressed air. Remove from dust box and tap clean.
