Before Use - GMC GPDA Manual Del Usuario

Before Use

WARNING: Ensure the tool is disconnected from the power supply before attaching or
changing any accessories, or making any adjustments.
Handle assembly
1. Fit the Front Handle (4) over the Handle Mounts (10)
2. Fasten into place using the Hex Bolts (9) provided
Note: The Front Handle position can be altered by loosening the Hex Bolts, moving the
handle into the desired position, and retightening the Hex Bolts.
Fitting bonnets, polishing sponges and discs
• The Hook and Loop Polishing Sponge (1) and other sanding/polishing accessories, such
GB
as 150mm Hook & Loop Sanding Disks (not included) can be pressed onto the face of the
Hook and Loop Backing Pad (2)
• Slowly pull the fitted attachment off the hook and loop backing pad to remove
Note: Always make sure both hook and loop surfaces are free of dirt and debris prior to
attaching any items (also see remarks in the 'Maintenance' section).
Operation
WARNING: ALWAYS wear eye protection, adequate respiratory and hearing protection,
as well as suitable gloves, when working with this tool.
Switching on and off
WARNING: Never switch the tool on or off when it is in contact with the workpiece. This
can cause serious injury to the operator and will significantly shorten the service life of the
On/Off Switch (5).
1. Connect the machine to the mains power supply
2. To start the machine, move the On/Off Switch (5) forwards into the 'I' position. The motor
will start and take a few moments to reach full operating speed
3. To stop the machine, move the On/Off Switch back into the 'O' position
Adjusting the tool speed
• The speed of the machine is controlled using the Variable Speed Dial (9): a higher number
indicates a higher speed setting
• The operating speed needs to be manually set with the tool off. Restart the tool after
setting the speed using the Variable Speed Dial to perform operations at the newly
determined speed
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 accessory.
Polishing tips
• Ensure the area to be polished is clean and dry
• Choose only polishing compounds that are compatible with the material to be polished,
and with the method of application. Read and understand all information supplied with your
polishing compound before use
• If using polishing sponges, apply polishing compound evenly to the polishing sponge and
place the sponge against the work surface
• Hold the machine securely, using both hands, by the handles provided. The polishing
sponge should make only light contact with the work surface
• Switch on the machine, and work across the surface using a wide 'sweeping' motion. Stop
and apply extra compound as required
• When the entire surface has been covered, stop the machine and allow the compound to
dry (follow manufacturer's guidance)
• Attach a clean polishing bonnet to the machine and work across the surface as before,
until all visible polishing compound is removed
Sanding tips
WARNING: This machine is primarily designed as a polishing tool. It is suitable for light duty
sanding tasks, e.g. fine sanding as a preparation to polishing, but it has not been designed to
remove large amounts of material. Use a different type of sander, e.g. a belt sander, should
this be required.
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. The machine works in a rotary motion so it is not
necessary to work with the grain
• Only use the sander 'flat on' to the work. Tilting the sander onto its edge will damage the
workpiece
Accessories
A range of accessories and consumables, including polishing sponges, lambswool bonnets,
hook and loop sanding disks and polishing compounds, 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 all the fixing screws are tight
• 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 the 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
Lubrication
• Slightly lubricate all moving parts at regular intervals with a suitable spray lubricant
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
• If you suspect that the brushes may be worn, have them replaced at an authorised GMC
service centre
