involved. Children and pregnant women MUST NOT enter the work area. DO NOT eat, drink or smoke in the
work area.
1. Push the tapered end of the Dust Extraction Collar on to the head of the tool so that it 'clips' into place
(Image B)
2. Slide the clip, located above the Dust Extraction port (7) into the groove, located below the power cord
(Image C)
3. Push a suitable vacuum hose on to the Dust Extraction Port
• The Dust Extraction Port is designed to fit a standard 32mm diameter hose
• For work in confined spaces, the Dust Extraction Port can easily be removed:
1. Remove any tools installed (see 'Fitting a blade or scraper')
2. Push the rear of the Dust Extraction Port (7) sideways to remove
Fitting a blade or scraper
1. Lift the Tool Change Lever (3) and push forward to disengage the clamping mechanism
Note: This requires some strength.
2. Fit a compatible blade or tool under the flange
3. Ensure correct orientation of the blade, so it sits within the locating pins on the flange
4. Tilt the Tool Change Lever into the original, closed position
5. Ensure the blade is securely fastened
Note: Blades or scrapers that are cranked or bent must be mounted on the tool so that the end of the blade
sits facing away from the machine (Image A)
Fitting the sanding pad and sanding sheets
1. Fit the hook and loop sanding pad by following the instructions under 'Fitting a blade or scraper'
2. Select the required sanding sheet for your intended task (see 'Selecting the right grade of sanding sheet'
below)
3. The Sanding Pad and sanding sheets use a hook and loop system for attachment. To mount the sheet
carefully line up one corner of the sheet with a corner of the Sanding Pad and gradually push the rest of
the sheet on to the pad, checking alignment as you do so, until the sheet is fitted correctly
Selecting the right grade of sanding sheet
• Sanding sheets are available in a variety of different grades: coarse (60 grit), medium
(120 grit) and fine (240 grit)
• Use a coarse grit to sand down rough finishes, medium grit to smooth the work, and fine grit to finish off
• Always use good quality sanding sheets to maximise the quality of the finished task
• It is advisable to do a trial run on a scrap piece of material to determine the optimum grades of sandpaper
for a particular job. If there are still marks on your work after sanding, try either going back to a coarser
grade and sanding the marks out before recommencing with the original choice of grit, or try using a new
piece of sandpaper to eliminate the unwanted marks before going on to a finer grit and finishing the job
Operation
WARNING: ALWAYS wear adequate personal protection equipment, including eye, hearing and
respiratory protection, when working with this tool.
WARNING: Anti-vibration gloves should be worn when operating this tool, to protect users from the
effects of vibration produced by the tool.
Switching on and off
1. Hold the tool firmly by the Grip (6), with the thumb over the On/Off Switch (4)
2. Slide the On/Off Switch forward until it locks, to switch the tool on
3. Slide the On/Off Switch backwards, to switch the tool off
WARNING: Allow the tool to reach the required speed before making contact with the workpiece.
WARNING: Motor vents allow heat generated from the motor to escape the body of the tool and must
not become blocked. Dust, wood chippings and swarf can block the motor vents and cause the tool to shut
down. Swarf, created when cutting metal, can also cause permanent damage if it enters the tool. Do not allow
dust, wood chippings and swarf to build up. Use a vacuum cleaner to keep the work space clean, especially in
confined areas, and when working with harmful substances.
WARNING: DO NOT inhale dust. Wear adequate breathing protection. Some dusts may be toxic especially
from man-made composite materials.
Adjusting the tool speed
• The oscillating speed of this multi-tool can be adjusted over the Variable Speed Dial (5)
1. Turn the Variable Speed Dial to a higher setting, to increase tool speed
2. Turn the Variable Speed Dial to a lower setting, to decrease tool speed
Note: Adjust tool speed to best suit the work carried out, and to adapt to material requirements. Also refer to
the accessory manufacturer's instructions, with regards to tool speed selection.
Sawing
• Ensure the saw blade is sharp and in good condition
• DO NOT use saw blades that are damaged or deformed in any way
• When sawing light building materials, follow the recommendations of the material suppliers
• Apply plunge cuts to soft materials ONLY, for example wood, plasterboard etc.
• If using saw blades not designed for cutting metal, ensure there are no nails or screws embedded in the
workpiece. If necessary, remove embedded objects or use metal cutting saw blades instead
Sanding
• The removal rate and the sanding pattern are determined by the type of sanding sheet, the preset
oscillation rate and the applied pressure
• Pay particular attention to applying uniform sanding pressure; this increases the working life of the
sanding sheets
• Intensifying the sanding pressure will not lead to an increase of the sanding capacity, but to increased
wear of the machine and premature wear of the sanding sheet
• For precise on-the-spot sanding of edges, corners and hard-to-reach areas, it is also possible to work
only with the tip or an edge of the sanding plate
• A sanding sheet that has been used for sanding metal should not be used for sanding other materials
• Regularly brush down or vacuum the surface being sanded to ensure the sanding sheet is in direct
contact with the surface
Scraping
• For scraping, select a high speed setting
• On soft surfaces (e.g. wood), work at a flat angle and apply only light pressure so that the scraper does
not cut into the surface
Accessories
• A full range of oscillating multi-tool accessories, including different saw blades, scrapers, grinding and
sanding accessories is available from your GMC stockist
Maintenance
WARNING: ALWAYS disconnect from the power supply before carrying out any maintenance/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
Lubrication
• Lubricate all moving parts with a suitable lubricant spray, at regular intervals
Cleaning
WARNING: ALWAYS wear protective equipment including eye protection and gloves when cleaning this tool.
• Keep your tool clean at all times. Dirt and dust will cause internal parts to wear quickly, and shorten the
device's service life
• Clean the body of your machine with a soft brush, or dry cloth
• Never use caustic agents to clean plastic parts. If dry cleaning is not sufficient, a mild detergent on a
damp cloth is recommended
