Before Use
WARNING: Ensure the tool is disconnected from the power supply before attaching or changing
any accessories, or making any adjustments.
Dust extraction
WARNING: Always connect the wall chaser to a suitable vacuum cleaner or workshop dust
extraction system if the cutting dust contains harmful substances, such as particles from old paint,
varnish, surface coatings, etc. Always dispose of harmful dust according to laws and regulations.
WARNING: Take special care to guard against harmful and toxic dusts when cutting lead-based
painted surfaces, woods and masonry, particularly if you are unsure about the exact substances
involved. All persons entering the work area must wear a mask specially designed for protection
against the toxic dust and fumes involved. Children and pregnant women MUST NOT enter the work
area. DO NOT eat, drink or smoke in the work area.
IMPORTANT: It is essential to take proper measures to prevent dust entering the motor and other
internal mechanisms of this tool. Failure to do so may seriously reduce the life and performance
of this tool.
1. Connect the tool to a vacuum cleaner, or dust extraction system, using the Dust Extraction Port
(15)
2. Turn the vacuum cleaner or dust extraction system on before you begin operating the tool
• This will significantly reduce the dust in the air around the work area
Note: A Dust Extraction Port Adaptor (24) is supplied for added vacuum/dust extraction tool
compatibility.

1700W Wall Chaser 150mm
Cutting
1. Carry out the procedure for switching the tool ON (see 'Switching ON & OFF' section)
2. Allow the motor to reach full speed, then position the wall chaser at the one end of the chase
(Fig. VII)
3. Slowly press the tool firmly against the workpiece, so that the Base Plate (11) is flat against the
surface, and move the tool slowly along the pre-marked channel.
4. Prevent the Discs from overheating by removing the tool from the load and running the motor at
full speed for approximately 30 seconds. DO NOT use water or cooling fluid to cool the Discs
Note: Running the tool without load will also cool the motor rather than just stopping the tool.
5. When the cut is complete, switch the tool OFF (see 'Switching ON & OFF' section), and allow the
Discs to come to a complete stop before putting down the tool
6. To form the chase, clear the block between the two cut lines using the Chisel (25) (Fig. IX) and a
