Dust extraction
WARNING: Always connect the sander to a suitable vacuum cleaner or workshop dust
extraction system if the sanding 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 sanding lead-
based painted surfaces, woods and metals, 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.
• This sander is designed to be connected to a household vacuum cleaner hose or
workshop dust extraction system. This is the preferred and most effective method of dust
extraction:
1. Fit the Dust Extraction Adaptor (11) to the Dust Extraction Port (4) in place of the Dust
Canister (7), (Image E)
2. Connect a suitable vacuum hose to the Dust Extraction Adaptor
Note: The Dust Extraction Adaptor is designed to fit a 32mm diameter hose.
• If no vacuum dust extraction system is available, the supplied Dust Canister (7) must be
used:
1. Attach the Dust Canister to the Dust Extraction Port (4) of the sander by pushing and
twisting the bayonet fitting, (Image F)
WARNING: For optimum dust extraction, remove and empty the Dust Canister when it is no
more than half full.
2. Remove the cap from the end of the Dust Canister (Image G) to access the internal Dust
Bag (12), (Image H) in order to replace or clean the bag. The Dust Bag can be washed,
but make sure it is completely dry before refitting
WARNING: Remove and DO NOT use the Dust Canister (7) when sanding metal. Hot metal
particles and sparks could ignite residual wood dust, or cause the Dust Bag (12) to catch
fire. Always connect the sander to a suitable workshop dust extraction system when sanding
metal. Always clean the tool THOROUGHLY when switching from sanding wood to sanding
metal, and vice versa.
Adjusting the speed
Note: The speed of this sander can be adjusted to suit the material being sanded.
• To adjust the speed, move the Variable Speed Control Dial (13) (Image I) until you are
satisfied that the speed is what you need for the job in hand: the higher the number shown
on the dial, the faster the speed
Operation
WARNING: Always wear safety goggles, an adequate dust mask, hearing protection and
suitable gloves, when working with this tool.
WARNING: Do not touch the moving sanding sheet.
Note: Always use clamps to secure your workpiece to the workbench wherever possible.
WARNING: NEVER allow the sandpaper to completely wear down before replacing it. Failure
to observe these precautionary measures can lead to damage to the hook and loop surfaces,
resulting in sanding sheets failing to attach properly.
Switching on and off
WARNING: Hold the tool securely and make sure that you have full control at all times.
1. Connect the plug to the power supply
Note: The PowerGLO Indicator (6) neon light will illuminate when the machine is supplied
with mains power.
2. Push the On/Off Switch (3) forward to start the machine
3. Pull the On/Off Switch back to stop the machine
WARNING: Always wait until the machine has stopped vibrating completely before putting it
down. Always disconnect from the power supply after use.
Sanding tips
• If the tool is connected to a vacuum dust extraction system, switch the extraction device on
before switching on the sander. Switch the sander off first, then the vacuum system
• Move the machine in a circular motion over the workpiece surface, applying an even,
moderate pressure until you reach the desired surface finish
WARNING: Excessive pressure does not lead to a faster removal of material; it will however
lead to premature wear of the sanding sheet, and may cause damage to the machine.
• If there are still scratches on your workpiece after sanding, refer to 'Selecting the right
grade of sanding sheet'
Accessories
• A range of accessories and consumables, including spare blades, is available from your
GMC stockist. Spare parts can be obtained from toolsparesonline.com
Maintenance
WARNING: ALWAYS disconnect from the power supply before carrying out any
inspection, maintenance or cleaning.
General inspection
• Regularly check that all the fixing screws are tight. They may vibrate loose over time
• Inspect the supply cord of the tool, prior to each use, for damage or wear. Repairs should
be carried out by an authorised GMC service centre. This advice also applies to extension
cords used with this tool
Cleaning
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and
shorten the machine's service life. Clean the body of your machine with a soft brush, or dry
cloth. If available, use clean, dry, compressed air to blow through the ventilation holes
• Clean the tool casing with a soft damp cloth using a mild detergent. Do not use alcohol,
petrol or strong cleaning agents
• Never use caustic agents to clean plastic parts
• Regularly check to see if any dust or foreign matter has entered the grills near the motor
and around the On/Off Switch (4)
Emptying the dust extraction canister
WARNING: Always wear respiratory protection, eye protection and gloves when emptying
the Dust Bag (12).
Note: For optimum dust removal, empty the Dust Bag when it is no more than half full.
1. To remove the Dust Canister (7), rotate it slightly to disengage the bayonet lock, and pull
the Dust Canister off the tool
2. Open the Dust Canister and remove the internal Dust Bag for cleaning
Note: If the sanding dust contains harmful substances, such as particles from old paint,
varnish, surface coatings etc., always dispose of according to laws and regulations.
Note: Always clean the tool THOROUGHLY when switching from sanding wood to sanding
metal and vice versa.
Hook and loop surfaces
• Hook and loop surfaces need to be clean, free of dirt and foreign matter, such as hair,
fibres, sand etc.
• In order to provide adequate adhesion for securing accessories, hook and loop surfaces
must be in good condition
• When used extensively, hooks and loops will become elongated or broken, and the
mechanism cannot provide the required strength of adhesion anymore
Note: This sander's hook and loop Sanding Bases are NOT a warranty items. Replacement
bases can be obtained through an authorised GMC service centre.
