Technical data

WARNING Avoid the risk of electric shock or severe injury. When the power cable gets damaged it should only be replaced by the manufacturer or at a **Authorized Service Center. The build quality of the electric insulation is altered if spills or liquid gets into the tool while in use. Do not expose to rain, liquids and/or dampness.
WARNING** Before gaining access to the terminals all power sources should be disconnected.

Power requirements

WARNING Tools with double insulation and reinforced insulation are equipped with a polarized plug (one prong is wider than the other). This plug will only fit in the right way into a polarized outlet. If the plug cannot be introduced into the outlet, reverse the plug. If it still doesn’t fit, call a qualified electrician to install for you a polarized outlet. Do not alter the plug in any way. Both types of insulation eliminates the need of both a grounded third power cord with three prongs or a grounded power connection.
WARNING When using an extension cable, verify the gauge is enough for the power that your product needs. A lower gauge cable will cause voltage drop in the line, resulting in power loss and overheating. The following table shows the right size to use depending on cable’s length and the ampere capability shown in the tool’s nameplate. When in doubt use the next higher gauge .

WARNING When operating power tools outdoors, use a grounded extension cable labeled “For Outdoors Use”. These extensions are specially designed for operating outdoors and reduce the risk of electric shock.

General power tool safety warnings

WARNING! Read carefully all safety warnings and instructions listed below. Failure to comply with any of these warnings may result in electric shock, fire and / or severe damage. Save all warnings and instructions for future references.

• Remove any wrench or vice before turning the power tool on.
• Wrenches or vices left attached to rotating parts of the tool may result in personal injury.
• Do not overreach. Keep proper footing and balance at all times.
• This enables a better control on the tool during unexpected situations.
• Dress properly. Do not wear loose clothing or jewelry. Keep hair, clothes and gloves away from the moving parts.
• Loose clothes or long hair may get caught in moving parts.
• If you have dust extraction and recollection devices connected onto the tool, inspect their connections and use them correctly.
• Using these devices reduce dust-related risks.

Power Tools Use and Care

• Do not force the tool. Use the adequate tool for your application.
• The correct tool delivers a better and safer job at the rate for which it was designed.
• Do not use the tool if the switch is not working properly.
• Any power tool that cannot be turned ON or OFF is dangerous and should be repaired before operating.
• Disconnect the tool from the power source and / or battery before making any adjustments, changing accessories or storing.
• These measures reduce the risk of accidentally starting the tool.
• Store tools out of the reach of children. Do not allow persons that are not familiar with the tool or its instructions to operate the tool.
• Power tools are dangerous in the hands of untrained users.

• This will ensure that the safety of the power tool is maintained.

Safety warnings for orbit sanders

• CAUTION Observe the applicable regulations when sanding painted surfaces. Use special care when the paint is lead-based.
• Remove dust and any other type of debris to assure a safe working environment. When possible use a vacuum cleaner or a dust extractor.
• CAUTION To be protected against dust and smoke generated when sanding everybody in the work area should wear a professional breathing mask.
• Do not use this tool for sanding pieces containing magnesium.
• After long work cycles the metallic outer parts and accessories may get hot.
• CAUTION Wear ****professional breathing mask and cartridges suited for paint dust and vapors. Regular painter masks do not offer the right protection.
• WARNING Do not allow children and pregnant women enter the work area.
• WARNING Remove the dust bag before sanding metal. Sparks may ignite dust and the inner pouch.
• Do not use worn or ripped sanding sheets.
• Do not touch the sandpaper when moving.
• Before sanding, double-check all foreign objects such as nails or screws are removed from the work piece.
• WARNING Hold the tool by the insulated grip, as the sander could make contact with its own power cord. Contact with a power cord makes the metal parts of the tool also have current and may result in a shock to the operator.

Parts

Preparation

Sanding Disc Selection

• Grains available vary from very coarse to very fine.
• Coarse grain is used to sand rough surfaces, medium grain, for light work and fine grain is for smooth finish.
• It is advisable to carry out tests over a disposable piece to determine the adequate grain for a particular job.
• Do not use the same disc for wood and for metal. Metal particles can get embedded in the sanding and ill-treat a wooden surface.

Installing a Sanding Disc

• WARNING Always double check the sander is off and disconnected from the power supply before installing the sandpaper.
• Select the right sanding grain.
• Remove dust and debris from the pad and it hook and loop base (A).
• Align the sanding disc orifices with the orifices in the pad. Press firmly. Proper alignment of the holes allows for dust suction to work.
• To remove the sanding disc tear it out from its base (B).
• CAUTION Clean regularly dust accumulated in the hook and loop base. Do not wait for the disc to be completely worn out before replacing it. Otherwise, the hook and loop base can get damaged and will lose adherence with the sandpaper.
• CAUTION The hook and loop base is considered as a consumable and is not covered by the Warranty.
• CAUTION If premature wear of the hook and loop fastening is occuring, it is possible that it is due to pressure being applied to the tool during operation.

Dust Extraction

• Before connecting the tool to the power supply, adjust the dust bag into the dust extraction duct in the rear or the sander (D).
• To get an optimal dust extraction, remove and empty the dust bag when is half-full.
• Use the dust bag when sanding wood.
• WARNING Do no use when sanding metal. The metal particles could ignite the residual wood dust or the inner pouch.
• Make sure to regularly clean the dust accumulated in the dust bag and the hook and loop base.

Start-up

Switch On

• Connect the plug into the power outlet.
• To start the tool, press switch (C) into the ON position ( I ).
• To shut off the tool, press the switch to the opposite side.
• CAUTION Do not start the tool when the sander surface is onto the work piece.
• Before shutting off the machine, keep it away from the work piece.

This sander was designed to sand wood, metal, plastic and similar materials. Can be used for repetitive sanding jobs and finishing. Due to its size, is ideal for final jobs.

Sander Operation

• Switch on the sander before setting it onto the work piece.
• Keep the sander base parallel to the work piece surface.
• Press lightly downwards onto the work piece. Make circular movements. Be sure the full sanding area is supported on the work piece.
• Ensure the pressure is moderated. Do not force the sander. Make it work at a reasonable speed. If too much pressure is applied, the motor speed could be slower due to overheating. It could cause insufficient sanding and damage to the motor.
• If after sanding, the surface is still showing marks, sand again with a coarser grain to eliminate the marks. Replace the sanding disc with the next one and finish sanding. Or, replace the worn sanding disc with a new one.
• Do not let the sanding disc be totally worn out. Replace it before this happens.

Maintenance

Cleaning and Care
Always keep the ventilation slots in the motor housing clean and free of obstructions. After each use apply compressed air. In the event of malfunctioning go only to a ****Authorized Service Center.

Carbon Brush Replacement

• Carbon brushes need to be checked regularly and when worn, replaced in a ****Authorized Service Center.
• After the carbons have been replaced, ask the technician to inspect if they run freely in the carbon housing and to let run the machine 5 minutes to make even the contact of carbon and commuter.
• Use only ****original spare carbon brushes, designed specifically with the strength and electric resistance fit for each type of motor. Carbon brushes that are out of specifications may damage the motor.
• When replacing carbon brushes always change both pieces.
