Attaching The Dust Bag

The dust bag provides a dust collection system for the sander. Sanding dust is drawn up through the holes of the sanding platen and collected in the dust bag during sanding. To attach the dust bag:

1.Unplug the sander.

2.Line up the “unlock” symbol on the dust bag with the arrow on the dust collection port and slide the bag assembly onto the port. To lock in place, rotate the bag until the arrow on the port aligns with the “lock” symbol on the bag.

Attaching the Sander to a Vacuum

You can easily attach the dust collection system of the sander to a vacuum.

1.Unplug the sander.

2.Remove the dust bag from the sander.

3.Attach vacuum hose to blower exhaust.

NOTE: Smaller vacuum hoses fit inside blower exhaust. Larger vacuum hoses fit outside blower exhaust.

4.Connect sander and vacuum to power supply.

General Sanding with 1/4 Sheet Sanders

When using sanders there are a few things to keep in mind:

• Varying pressure applied to the sander will affect

its speed. A light pressure is recommended for

fine work, moderate pressure for rough work.

Excessive pressure does not allow the pad to

move enough.

• Keep sanding pad flat on the workpiece. Tipping

the sander or using the edges of the pad may

produce an uneven finish, and reduce pad life.

WARNING To reduce the risk of fire and explosion, paint solvents and varnish removers must be removed from the work- piece and the workpiece must be completely dry before sanding.

3.

Select a coarse grit sandpaper disc to help pre-

 

vent the sandpaper from clogging.

4.

Keep the sander moving over new areas to avoid

 

heating and softening the old coating (paint or

 

varnish).

WARNING When sander is not con-

 

nected to vacuum, always reinstall dust bag

 

assembly back onto sander. Failure to do so

 

could cause sanding dust or foreign objects to

 

be thrown into your face or eyes which could

 

result in possible serious injury.

OPERATION

• Keep sander moving in broad even strokes

across the workpiece. Sanding in one spot too

long can cause gouging and uneven results.

1.To prevent rough action due to starting under load, turn ON/OFF Switch ON before applying sander to workpiece.

2.Work in slow, overlapping strokes parallel to grain. Your Finishing Sander is designed for even weight distribution. Excessive pressure may damage workpiece and motor as well as cause premature sandpaper wear.

3.Repeat operation using successively finer grits of sandpaper until desired finish is obtained. Example: 60 Coarse, 100 Medium, 150 Fine.

WARNING Properly secure workpiece before sanding. Unsecured work could be thrown towards the operator causing injury.

WARNING Do not wear loose cloth- ing or jewelry when operating sander. They could get caught in moving parts causing serious injury. Keep head away from sander and sanding area. Hair could be drawn into sander causing serious injury.

5.

Work in wide, overlapping strokes to produce a

 

uniform finish.

6.

As the workpiece begins to show through the old

 

coating, switch to a medium grit sandpaper disc

 

to avoid scratching the surface of the workpiece.

 

Gradually switch to a fine grit sandpaper until

 

you achieve the desired finish.

Emptying the Dust Bag

WARNING Collected sanding dust from sanding surface coatings such as poly- urethanes, linseed oil, etc. can self-ignite in the sander dust bag or elsewhere and cause fire. To reduce the risk of fire always empty the dust bag frequently (10-15 minutes) while sanding and never store or leave a sander without totally emptying its dust bag. Also follow the recommendations of the coatings manufacturers.

For more efficient operation, empty the dust bag when it is no more than half full. This will permit the air to flow through the bag better. Always empty and clean the dust bag thoroughly upon comple- tion of a sanding operation and before placing the sander in storage.

WARNING To reduce the risk of injury, always unplug tool before attaching or remov- ing accessories or making adjustments. Use only specifically recommended accessories. Others may be hazardous.

WARNING To reduce the risk of injury, wear safety goggles or glasses with side shields.

Starting and Stopping the Tool

To start the sander, switch ON/OFF Switch to ON.

To stop sander, switch ON/OFF Switch to OFF.

WARNING Finish sanding can produce clouds of fine dust that could ignite in the presence of sparks or open flame. Always wear a suitable dust mask or respirator and use your sander in a well-ventilated area.

WARNING To reduce the risk of injury, inspect for and remove all raised nails and fasteners from workpiece before sanding. Striking a fastener while sanding could cause loss of control.

Removing Paint or Varnish

1.When removing several layers of paint or var- nish, remove as much as possible with a paint solvent or varnish remover.

2.Scrape away the residue with a putty knife or other scraping tool and allow the surface to cool and dry before applying sander to the workpiece.

To empty the dust bag:

1.Unplug the sander.

2.Remove the dust bag from the sander.

3.Shake out the dust.

4.Reattach the dust bag to the sander.
