ASSEMBLY

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 Always remove battery

pack before changing or removing acces-

sories. Only use accessories specifically

recommended for this tool. Others may be

hazardous.

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 ﬁ lter in place.

CAUTION Keep ﬁ lter clean. Efﬁ ciency of

the HAMMERVAC™ is largely dependent on

the ﬁ lter. A dirty ﬁ lter will reduce the air ﬂ ow

and overall efﬁ ciency of the system. Do not

clean with water or compressed air. Remove

from dust box and tap clean.

Attaching the HAMMERVAC™ to a Rotary

Hammer/Hammer Drill

The HAMMERVAC™ is provided with three clamp-

ing collar assemblies and one side handle grip.

Choose the correct clamping collar assembly for

the tool being used (see Speciﬁ cations). The side

handle grip should be unscrewed from one as-

sembly to be used on another.

1. Turn OFF, remove the battery pack from the

HAMMERVAC™, and disconnect power from

the tool.

2. Remove the tool side handle.

3. Partially screw side handle grip onto clamping

collar assembly

4. Slide the HAMMER-

VAC™ side handle

clamping collar as-

sembly over the

chuck and onto the

neck of the tool. The

clamp lever must be

facing up (3).

5. Attach the side han-

dle clamping collar

assembly onto the

HAMMERVAC™, ﬁ rst

the upper jaw, then

lower jaw.

6. Press down the clamp lever (3) to secure the

clamping collar assembly to the HAMMER-

VAC™.

7. Rotate the HAMMERVAC™ and side handle

grip to the desired position, and tighten securely.

Adjusting the Side Handle Position

1. Loosen the side handle clamping collar assembly

by unscrewing the side handle grip until the side

handle clamping collar assembly rotates freely.

2. Rotate the side handle grip to the desired posi-

tion.

3. Tighten the side handle grip securely.

Installing/Removing the Bit

Slide the bit through the nozzle and then install

into the tool according to the tool manufacturer's

instructions. For best results, use a bit 6" in length

or shorter.

Fitting the HAMMERVAC™ to the Tool and Bit

For proper suction and depth control, position the

nozzle assembly so the bit is ﬂ ush 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 ﬂ ush 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.

Setting the Drilling Depth

1. Fit the HAMMERVAC™ to the Tool and Bit.

2. Press and hold the depth gauge button and

slide the depth gauge to the desired depth. The

drilling depth is the last visible measurement

shown when viewed from the top of the tool.

Drill Depth

To ensure the HAMMERVAC™ is properly set

to the tool, bit, and desired depth, always drill

a test hole.

Installing/Removing the

Dust Box and HEPA Filter

To remove the dust box:

1. Turn OFF the tool.

2. Remove the battery pack.

Press the dust box latch down.

4. Pull the dust box away from

the HAMMERVAC™.

5. Empty dust from the dust box.

6. If necessary, pull the HEPA

ﬁ lter away from the dust box

and tap clean. Do not clean

with water or compressed

air. After about 1500 holes or

loss of suction, discard and

replace HEPA ﬁ lter (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.
