j. Empty the dust bag or container (where applicable) frequently during use, before
taking breaks and after completion of sanding. Dust may be an explosion hazard. DO
NOT throw sanding dust into an open fire. Spontaneous combustion may occur when oil
or water particles come into contact with dust particles. Dispose of waste materials
carefully and in accordance with local laws and regulations.
k. Work surfaces and sandpaper can become very hot during use. If there is evidence
of burning (smoke or ash), from the work surface, stop and allow the material to
cool. DO NOT touch work surface or sandpaper until they have had time to cool
l. DO NOT touch the moving sandpaper
m. ALWAYS switch off before you put the sander down
n. DO NOT use for wet sanding. Liquids entering the motor housing can cause severe
electric shocks
o. ALWAYS unplug the sander from the mains power supply before changing or
replacing sandpaper
p. Even when this tool is used as prescribed it is not possible to eliminate all residual
risk factors. If you are in any doubt as to safe use of this tool, do not use it

Intended Use

Mains-powered portable wall sander for sanding plastered walls and ceilings, smoothing
plaster surfaces, and removing loose plaster, paint and adhesive coatings.

Unpacking Your Tool

• Carefully unpack and inspect your new sander. Familiarise yourself with all its features
and functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing
or damaged, have such parts replaced before attempting to use this tool

Before Use

WARNING: Ensure the tool is disconnected from the power supply before attaching or
changing any accessories, or making any adjustments.
• The tool is supplied folded in for storage and transport. Unfold the tool and lock in position
using the Locking Clip (9), (Fig. I). Check the Short AC Cable (10) is securely fitted and not
damaged. Reverse the Locking Clip procedure when storing or transporting after use
• Ensure the Hook & Loop Pad (14) is securely attached, especially if this is the first use
after purchase. If the securing bolt in the middle of the pad is loose, tighten before use,
(Fig. II)
• Fit a sanding sheet carefully so the holes of the sheet line up with the holes of the Hook
& Loop Pad, (Fig.III). This is important so the dust extraction works correctly. Always
purchase perforated replacement sanding sheets for optimal dust extraction and sanding
• Connect the Hose (16) by inserting the Hose Connector (17) into the Main Collar (15).
Unscrew the Main Collar, then insert the Hose Connector, (Fig. IV). Retighten the Main
Collar securing the Hose Connector
• Connect the hose of your dust extraction system or vacuum cleaner to the Vacuum
Connector (15) ensuring it is securely fitted. The vacuum connector has a 32mm inner
diameter. If you require a different size fitting, an adaptor may be required to convert your
extraction system or vacuum cleaner hose connector to 32mm
Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection,
as well as suitable gloves, when working with this tool.
Adjusting vacuum power
• Adjust the Vacuum Adjuster (6) to vary the vacuum power for dust extraction and vacuum
cleaners that do not have a variable power control built in. The wider the hole is opened,
the weaker the suction will be, (Fig. V). The correct level of suction allows smooth easy
movement of the Sanding Base (13) with adequate suction to remove all dust generated
by sanding
Note: Leaving a very small hole open can help protect the motor of your extraction system or
vacuum cleaner if a blockage occurs
Adjusting sanding speed
• Adjust the rotating speed of the wall sander by turning the Speed Adjustment Dial (4).
Select a speed that works well with the vacuum extraction power and allows the easiest
control of the sander on the surface being sanded
Switching on and off
• To switch on the sander depress the On/Off Trigger Switch (8). Press the Lock-On Button
(4) before depressing the On/Off Trigger Switch to lock the sander into the 'on' position. To
switch off in either mode, depress and release the On/Off Trigger Switch
Using the sander
WARNING: Switch on the dust extraction system or vacuum cleaner before operating this
tool. The operator must also wear a suitable dust mask and safety glasses or goggles.
• Keep both hands on the handles of the tool. Hold the tool with the Insulated Handle (2)
and Main Handle (5), (Image A)
• Do not control the Sanding Base (13) with your hands: it will angle itself correctly in use
• Take time to make sure the operator, sander and extraction system are positioned correctly
before switching on the tool
• If the operator is directly below the Sanding Base when sanding ceilings (Image B), there
is greater risk of dust and debris entering the eyes, mouth or nose
• This tool is not designed for sanding dense rough surfaces, such as uneven concrete.
Attempting to do so may damage the Motor (11) and Hook & Loop Pad (14), and may
make the tool difficult to control
• Do not apply pressure to the Sanding Base during operation. This may damage the Motor,
Hook & Loop Pad and sanding sheet
