Before Use

WARNING: Ensure the tool is disconnected from the power supply before
attaching or changing any accessories, or making any adjustments.
Fitting the front handle
GB
• The Front Handle (13) must be fitted to the machine before use:
1. Screw the Front Handle to either the Left Side Handle Thread (12) or the Right
Side Handle Thread (16) to suit the task at hand and operator
2. Angle the Front Handle to the required position
3. Ensure the Grip of the Front Handle is tightly screwed in without over-tightening
Fitting and removing the sanding drum

heavily worn beyond normal use.
1. Remove the existing drum or accessory by pressing and holding the Spindle Lock
Button (11) with one hand
2. Remove the washer and bolt (see Image II), by unscrewing the bolt anti-clockwise
using the supplied spanner. It will freely rotate until the spindle lock engages, and

the Drum Spindle
4. Slide the new drum or accessory over the Drum Spindle (10). Insert BOTH drum
pins as seen in Image I to secure

sleeve and match it to the Rotation Direction Indicator (14) marked on the tool
3. Slide the sanding sleeve over the Sanding Sleeve Drum (17)
4. Check the sleeve is secure on the drum before use
Adjusting the guard
• The Guard (1) must be adjusted so that it is situated between the drum and
the operator. Reset the Guard if the work angle or the position of the operator
changes. Seek professional guidance if you are unsure how to operate the guards
or any other safety features of the machine correctly
• The Guard can be moved through a range of 360°, so that it can be placed
between the drum and the operator at any required work angle
• Loosen the Guard Securing Bolt (8), reposition as required and re-tighten the
Guard Securing Bolt
Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing
protection, as well as suitable gloves, when working with this tool.
WARNING: Using the steel wire brush drum with steel and other ferrite metals may
cause sparks, which may ignite flammable gas or flammable material, for example
paper, wood dust and metal swarf. Ensure the work area is free of such materials and
ensure there is a suitable extinguisher to hand.
IMPORTANT: Ensure the Motor Vents (6) are kept clean during use. Metal swarf and
wood dust entering the tool can damage or destroy it.
IMPORTANT: Stop frequently while operating to clean the work area and prevent a
build-up of swarf and dust. Where possible have a dust extraction system operating
around the work area.
Switching on and off
Note: DO NOT switch the machine on or off when the sanding drum is in contact with
the workpiece. ALWAYS allow the motor to reach its full speed before applying load,
and to stop completely before placing the sander down. ALWAYS hold the machine
securely, using both hands, on the handles provided
• To switch the machine on, grip the Rear Handle (4) and Front Handle (13) firmly
and depress the On/Off Trigger Switch (5)
• To stop the machine release the On/Off Trigger Switch
• The tool can be locked into the 'On' position using the Lock-On Button (3).
Depress the On/Off Trigger Switch then press in the Lock-On Button (3) to engage.
To switch off, release by depressing and releasing the On/Off Trigger Switch
Adjusting the tool speed
• The speed of the machine is controlled using the Variable Speed Control (2): a
higher number indicates a higher speed setting. See fig. III
WARNING: Always set the speed control dial to the correct speed for the task at
hand.
WARNING: Never exceed the maximum speed of the installed sanding drum or
accessory.
Polishing tips
IMPORTANT: To achieve a perfectly smooth polished surface do not skip more than
one grit size when switching from a coarse grit to a fine grit.
• Ensure the area to be polished is clean and dry
• Choose only polishing compounds that are compatible with the material that
requires polishing, and with the method of application. Read and understand all
information supplied with your polishing compound before use
• When the entire surface has been covered, stop the machine and allow the
compound to dry (follow manufacturer's guidance)
Sanding tips
WARNING: NEVER use this machine for wet sanding.
WARNING: ALWAYS use adequate respiratory protection when sanding.
• Allow the machine to reach the required speed before bringing the sanding paper
into contact with the workpiece
• Start with a coarse grit paper, and work through progressively finer grit papers until
the desired finish is achieved
• Apply only moderate pressure to the sander. Pressing too hard onto the work
surface may overheat the motor or damage the work surface
• Sand evenly over the work surface.
