the cutting path.
Always ensure that an appropriate blade is used for the material being cut.
•
Do not apply any sideways, or twisting, force to the blade whilst cutting.
•
Allow the blade to come to a complete stop before lifting out of cut.
•

•
disc lock nut with the Wrench (13). IMPORTANT NOTE: The disc lock nut
has a right hand thread. Turn CLOCKWISE TO LOOSEN.
Remove the disc lock nut.
•
Adjust cutting disc assembly with spacers as needed for cutting width
•
required.
Reinsert disc assembly and secure with disc lock nut.
•
Re-tighten the disc lock nut (turn anti-clockwise) and check blades are
•
fully secured in position
Replace the cover plate
•
Setting the cutting depth
Loosen the Depth Adjustment Lever (4).
•
You can now adjust the depth guard up or down as necessary to a
•
maximum cut depth of 44mm.
•
Use Depth Adjustment Lever (4) to lock the Base Plate (10) to provide
cutting depth required.
Fitting the dust extractor
Screw the black Dust Extraction Chamber (7) to the dust extraction port.
•
Now screw the White Extract Tube (8) to the outlet port of the dust
•
extraction chamber.
You can connect a dust collection bag or extraction system to the end of
•
the white extract tube.
Operating the wall chaser
Fit the dust extraction system and adjust cutting width and depth
•
as necessary
Mark a reference line on the wall at the centre line of the chase you require
•
Hold the unit firmly with both hands, one on the Rear Handle (1), one on
•
the Front Handle (5)
Start the motor by depressing the safety Lock-Off Button (3) and
•
squeezing the Trigger (2)
Allow the motor to reach full speed, then apply the wall chaser at the top
•
end of the chase required
Press firmly so that the base is flat against the wall and move the tool
•
slowly down the wall following the reference line you have marked
Remove the chaser from the wall and release the trigger to switch off
•
the machine
Allow the cutting discs to come to a complete stop before putting the
•
unit down
To form the chase, clear the block between the two cut lines with a chisel
•
If the discs get too hot, cool the discs by taking the tool off load and
•
running it freely for 30 seconds or so. DO NOT use water or cooling fluid
Maintenance
WARNING:
Always ensure that the machine is disconnected from
the mains power supply before performing any maintenance
procedure.
Changing the discs
Use only dry diamond segment cutting discs.
•
Only fit blades that are in perfect condition. Blunt, bent and cracked
•
blades should be discarded.
Fit new blades using method as described above in ‘Setting the cutting
•
width’.
Ensure the blades are fully secure before use.
•
Cleaning
Keep the tool clean at all times. Dirt and dust will cause the machine’s
•
internal parts to wear quickly, and shorten its service life.
Clean the body of the tool with a soft brush or dry cloth. If available, use
•
clean and dry compressed air to blow through the ventilation holes.
Brushes
Over time the carbon brushes inside the motor may become worn.
•
Excessively worn brushes may cause loss of power, intermittent failure
or visible sparking.
To replace the brushes:
Unscrew the Brush Access Plugs (6) and remove the worn brushes.
•
Insert new brushes and refasten the brush access plugs.
