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 insulation types eliminate 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.

• It is safe to use only if the extensions have a built-in artifact for over current protection.
  AWG = American Wire Gauge. Reference: NMX-J-195-ANCE

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.

Safety warnings for Sanders

CAUTION

• Observe applicable regulations when sanding painted surfaces. Use extra 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 to sanding pieces containing magnesium or asbestos.
• After long work cycles the metallic outer parts and accessories may get hot.

CAUTION

• Use a 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 collecting container (not included) before sanding metal. Sparks may ignite dust and the inner pouch.
• Do not use worn or ripped sanding sheets.
• Do not touch the sanding sheet when moving.
• Before sanding, double-check all foreign objects such as nails or screws are removed from the work piece.

Parts

Start Up

Selecting the Sanding Sheet

• Before setting up the sander select the right grain for the job.
• Grains available vary from very coarse to very fine.
• Coarse grain is used to sand rough surfaces, medium grain for light work and fine, for finishing purposes.
• Is advisable to test with disposable pieces to determine the right grain for each particular job.
• Do not use the same sheet to sand wood or metal. Metal particles may embed into the sander and damage the wood surface.
• In case the sanding sheet installed has no matching orifices, punch the holes so that the dust extraction system works right.

Installing the Sanding Sheet

• To install the sanding sheet, release the clamps on both sides of the sander.
• Set one end of the sanding sheet under one of the clamps and secure. Pull the other end so it stays uniformly onto the base.
• Verify the orifices (if any) match those in the base. Then adjust the other side.
• The sheet must be perfectly fastened; otherwise there could be excessive wear in the base.
  CAUTION Do not keep on using the tool if the sanding sheet is worn or damaged.

Dust extraction with vacuum cleaner

• Before connecting the tool to the power, place the vacuum cleaner adapter in the dust extraction duct.
• Connect the hose or extension tube of the vacuum cleaner to the adapter.

Sander Operation

• Turn on the sander before setting it on the work piece. Hold it with both hands, one in the handle, the other in front handle.
• Keep the sander base parallel to the work piece surface.
• Press downwards making circular movements and verifying the entire sander base is supported on the work piece.
• Use moderate pressure. Do not force the sander. Run in at a moderate speed. Overheating may occur if too much pressure is applied. The motor will run slow leading to inefficient sanding and damage to the motor.
• If after sanding you see marks on the work piece surface sand again using a sanding sheet with coarser grain to eliminate the marks. To finish the sanding operations, replace back the previous sanding sheet. Replace the worn sheet with a new one.
• Do not wear out the sanding sheet completely. Replace before starts wearing out.

Start Up and Operation Control

• Intermittent Operation:
  Connect the plug into the power outlet.
  To turn on the tool, press switch (A).
