IMPORTANT SAFETY

INSTRUCTIONS

READ ALL INSTRUCTIONS BEFORE

USING THIS DUST EXTRACTOR



WARNING: To reduce the risk of fire,

electric shock, or injury:

• DO NOT allow to be used as a toy. Close attention

is necessary when used by or nearchildren.

• USE ONLY as described in this manual. Use only

manufacturer’s recommendedattachments.

• DO NOT use with damaged cord or plug. If

appliance is not working as it should, has been dropped, damaged, left outdoors, or dropped into water, return it to a servicecenter.

• DO NOT handle plug or appliance with

wethands.

• DO NOT put any object into openings. Do not use

with any opening blocked; keep free of dust, lint, hair, and anything that may reduce airflow.

• KEEP hair, loose clothing, fingers, and all parts of

body away from openings and movingparts.

or smoking, such as cigarettes, matches, or hotashes.

• DO NOT use without dust bag and/or filters

inplace.

SAVE THESE INSTRUCTIONS

Personal Safety

a ) Prevent unintentional starting. Ensure the switch

is in the off-position before connecting to battery pack, picking up or carrying the appliance.

Carrying the appliance with your finger on the switch or energizing appliance that have the switch on invitesaccidents.

b ) Disconnect the battery pack from the appliance

before making any adjustments, changing accessories, or storing appliance. Such preventive

safety measures reduce the risk of starting the applianceaccidentally.

c ) Recharge only with the charger specified by the

manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another batterypack.

d ) Use appliances only with specifically designated

battery packs. Use of any other battery packs may create a risk of injury andfire.

e ) When battery pack is not in use, keep it away

from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may

cause burns or afire.

f ) Under abusive conditions, liquid may be ejected

from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

g ) Do not use a battery pack or appliance that

is damaged or modified. Damaged or modified

batteries may exhibit unpredictable behavior resulting in fire, explosion or risk ofinjury.

h ) Do not expose a battery pack or appliance

to fire or excessive temperature. Exposure to fire or temperature above 265°F (130°C) may causeexplosion.

i ) Follow all charging instructions and do not

charge the battery pack or appliance outside of the temperature range specified in the instructions. Charging improperly or at temperatures

outside of the specified range may damage the battery and increase the risk offire.

Additional Safety Information



WARNING: ALWAYS use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETYEQUIPMENT:

• ANSI Z87.1 eye protection (CAN/CSA Z94.3),

• ANSI S12.6 (S3.19) hearing protection,

• NIOSH/OSHA/MSHA respiratoryprotection.



WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicalsare:

• lead from lead-based paints,

• crystalline silica from bricks and cement and other masonry products, and

• arsenic and chromium from chemicallytreatedlumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopicparticles.

• Avoid prolonged contact with dust from power

sanding, sawing, grinding, drilling, and other construction activities. Wear protective clothing and wash exposed areas with soap and water. Allowing

dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmfulchemicals.

ENGLISH

• Do not use without dustbox and/or filter inplace.

• Do not use the appliance to pick up flammable or

combustible liquids, such as gasoline, or use in areas where flammable or combustible liquids arepresent.

• Do not pick up anything that is burning or smoking, such as cigarettes, matches or hotashes.

• To avoid spontaneous combustion, empty dust box after eachuse.

• Do not leave dust extractor unattended when battery is installed. Remove battery pack when not in

use and beforeservicing.

• Do not put any objects into the openings. Do not use with any opening blocked; keep free of dust, lint, hair and anything else that may reduce airflow.



WARNING: Use of this tool can generate and/ or disburse dust, which may cause serious and permanent respiratory or other injury. Although the filter material removes 99.97% of airborne particles

0.3 microns or greater, the dust extration system may not capture all of the dust created by the drilling operation. Always use NIOSH/OSHA approved respiratory protection appropriate for the dust exposure. Direct particles away from face andbody.



WARNING: Always wear proper personal hearing protection that conforms to ANSI S12.6 (S3.19) during use. Under some conditions and duration

of use, noise from this product may contribute to hearingloss.



CAUTION: When not in use, place tool on its side on a stable surface where it will not cause a tripping or falling hazard. Some tools with large

battery packs will stand upright on the battery pack but may be easily knockedover.

• Air vents often cover moving parts and should be avoided. Loose clothes, jewelry or long hair can be caught in movingparts.



WARNING: For your own safety, read the tool instruction manual before using any accessory. Failure to heed these warnings may result in personal injury and serious damage to the tool and the accessory. When servicing this tool, use only identical replacementparts.

ENGLISH



WARNING: Do not use the tool without the filter inplace.

Proper Hand Position (Fig. F)



WARNING: To reduce the risk of serious personal injury, ALWAYS use proper hand position as shown.



WARNING: To reduce the risk of serious personal injury, ALWAYS hold securely in anticipation of a suddenreaction.

Proper hand position requires one hand on the main handle of the hammer and one hand on the side handle. The side handle must be installed for properuse. Fig. F

Switch

The extraction system automatically starts when the rotary hammer is turnedon.

Since your dust extractor is mechanically powered by the rotary hammer, continue running the tool after drilling is complete for a few seconds longer to vacuum the remaining dust particles in the internal parts and collect the dust in the dust collectionbox.

Filter Cleaning Mechanism

The filter cleaning mechanism is a feature that uses the motor in the rotary hammer to force air through the HEPA filter. Refer to Emptying the Dust Collection Box for instructions on properuse.

Setting the Drilling Depth (Fig. A)

Press the depth adjustment button

6

on top of the front slider and move it to the desired drilling depth. Release thebutton.

Adjusting the Drill Length (Fig. A)

1. Insert the appropriate drill bit. The dust extractor head is designed for bits up to 1" (25 mm)diameter.

2. Hold the dust extraction head

8

against awall.

3. Push the tool to make the drill bit touch thesurface.

4. Press the length adjustment button

7

on top of the back slider and move it to the desired length. Release thebutton.

5. Gently withdraw the tool assembly from the wall, taking care that the spring-loaded mechanism does notrelease.
