Attach Drilling Dust Extraction System to Vertical or

Horizontal Surface (Fig. 1, 3, 8, 9)

The dust extraction system (D) has a suction system that allows the unit to be fixed into place

on a vertical or horizontal surface.

1. With the correct drilling head (G, H) fitted and the drilling dust extraction system securely

connected to the dust extractor vacuum, turn the dust extractor vacuum on as instructed in

the dust extractor vacuum instruction manual.

2. Depress and hold the quick release buttons (E) and place the dust extraction system (D) on

surface to be drilled.

NOTE: The suction system will not hold the unit in place on very rough or uneven surfaces.

Secure the dust extraction system in place as shown in figure 9 if drilling on an uneven

horizontal surface.

3. Release the quick release buttons (E) and the dust extraction system will be secured in

place.

4. To make fine location adjustments, depress the quick release buttons (E) and the seal will

release so the unit can be moved or removed from the surface completely.

WARNING: To reduce the risk of injury, DO NOT turn off the dust extractor vacuum before

removing the drilling dust extraction system from the surface as instructed. Turning off the dust

extractor vacuum before removing the drilling dust extraction system from the surface will cause

the drilling dust extraction system to fall from the surface possibly causing injury.

Remove Drilling Dust Extraction System From Surface

(Fig. 1, 3)

WARNING: To reduce the risk of injury, DO NOT turn off the dust extractor vacuum before

removing the drilling dust extraction system from the surface as instructed. Turning off the dust

extractor vacuum before removing the drilling dust extraction system from the surface will cause

the drilling dust extraction system to fall from the surface possibly causing injury.

Depress the quick release buttons (E) on the dust extraction system to remove it from the

surface.

Attach Hole Cleaning Nozzles (Fig. 1, 6, 7)

Hole cleaning is required to expose the full drilled depth and when using certain types of

chemical fixing anchors to ensure maximum adhesion.

1. Select the correct hole cleaning nozzle to be used:

• Hole cleaning nozzle (A): used for small holes 0.32"–0.56" (8–14mm) in diameter.

• Hole cleaning nozzle (B) used for holes 0.56" (14mm) in diameter and above.

2. Remove/replace hole cleaning nozzle:

Grip the nozzle (A, B) firmly and pull it from the connection point (J).

Push the nozzle into the connection point (J) until it stops.

3. Push the dust extractor vacuum hose nozzle (K) into the connection point (C) until tight. For

a more secure connection the AirLock connection system may be used.

NOTE: Ensure hose connection is secure.

OPERATION

WARNING: ALWAYS turn off tool and disconnect the tool from the power source

before making any adjustments or removing or installing attachments or accessories.

This applies to both the drill and the dust extractor vacuum. Such preventative safety

measures reduce the risk of starting the tool accidentally.

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.

NOTE: The amount of dust retained by the dust extractor vacuum is dependent on its filter

system. Refer to the dust extractor vacuum instruction manual for more information.

1. Complete the Attach Drilling Dust Extraction System to Vertical or Horizontal

Surface procedure. The unit is now ready to use.

2. Place the drill bit into the center of the drilling head (G, H) and proceed to drill as shown.

Hole Cleaning (Fig. 10)

1. Complete the Attach Hole Cleaning Nozzles procedure.

2. Turn the dust extractor vacuum on as instructed in the dust extractor vacuum instruction

manual.

3. Place the hole cleaning nozzle (A, B) into hole to be cleaned.

MAINTENANCE

WARNING: ALWAYS turn off tool and disconnect the tool from the power source

before making any adjustments or removing or installing attachments or accessories.

This applies to both the drill and the dust extractor vacuum. Such preventative safety

measures reduce the risk of starting the tool accidentally.

Your drilling dust extraction system has been designed to operate over a long period of time

with a minimum of maintenance. Continuous satisfactory operation depends on proper tool care

and regular cleaning.

TO REPLACE THE SUCTION PAD (FIG. 1)
