2. Align the interface of the attachment with the power tool guide and slide it on the tool until it locks with a double click
sound.
3. After installing the attachment on the power tool, make sure that it is secured properly.
To remove the dust collection system, follow the procedure below.
1. Hold the power tool so that finger(s) does not press the switch trigger. (Fig. 2)
2. Press the release button on the attachment and with the button pressed pull it away from the power tool.
OPERATION
CAUTION:
• Do not use the tool in wet conditions such as work on concrete surface and the similar.
Adjusting the tip protrusion length
The protrusion of the tip is adjustable according to your hammer drill bit length.
1. Hold the power tool so that finger(s) does not press the switch trigger. (Fig. 3)
2. CAUTION: When the stroke adjusting button is pressed, the telescopic section is released and then it may jump
out up to 100 mm under spring pressure. Wear goggles.
Keep the bar tip of the attachment away from any objects keeping the above jumping-out distance in mind and
never point the attachment at yourself, a bystander or animals.
Press the stroke adjusting button and keep pressing it.
NOTE:
• Before starting pressing the stroke adjusting button, push the nozzle forward.
3. Press the power tool with the hammer drill bit installed against the wall until the drill bit tip touches the wall.
4. Release the stroke adjusting button to lock it.
Setting the drilling depth (depth gauge)
If holes require to be drilled to an exact depth, the correct depth needs to be determined by drilling test holes.
1. Hold the power tool so that finger(s) does not press the switch trigger. (Fig. 4)
2. Press the depth gauge button and with the button pressed slide the lock button carriage to the desired length and
release it.
The distance (X) between the attachment housing and the depth gauge button is equal to the drilling depth.
Operation
CAUTION:
• Always follow the instruction in OPERATION of the instruction manual for Makita hammer drills. Failure to observe
the instruction manual may cause personal injury.
WARNING:
• Always follow national laws, regulations and ordinance which prescribe working with materials hazardous to health.
Drilling
When drilling into concrete, hold the power tool firmly with both hands so that the entire nozzle top keeps in tight contact
with the concrete surface. Any part of the nozzle away from the concrete surface may cause poor dust collection.
Beating dust on the filter (Fig. 15)
CAUTION:
• When using the tool with the dust collection system, be sure to attach the filter to the dust collection system to prevent
dust inhalation.
• Before using the dust collection system, check that the filter is not damaged. Failure to do so may cause dust
inhalation.
• Do not turn the dial on the dust case while the dust case is removed from the dust collection system. Doing so may
cause dust inhalation.
• Always switch off the tool when turning the dial on the dust case. Turning the dial while the tool is running may result
in the loss of control of the tool.
By beating the dust on the filter inside the dust case, you can keep the vacuum efficiency and also reduce the number
of times to dispose of the dust.
Turn the dial on the dust case three times after collecting every 50,000 mm
performance declined.
NOTE:
• 50,000 mm
of dust equivalents to drilling 10 holes of ø10 mm and 65 mm depth (14 holes of ø3/8" and 2" depth).
