SECTION 7: MAINTENANCE

GeneralLubrication

Make a habit of inspecting your sander each time you use it. Check for the following conditions and repair or replace when necessary.

1.Loose mounting bolts.

2.Worn switch.

3.Worn or damaged cords and plugs.

4.Worn or damaged V-belt.

5.Poor belt tensioning/tracking.

V- Belt

Without proper belt tension and correct pulley alignment, your sander will vibrate excessively and wear out the V-belt and the bearings much faster than normal. The pulleys can be aligned by placing a straightedge along the outside flanges and sighting down the straightedge. Move one pulley along the shaft until both pulleys are in line. Proper belt tension can be checked by squeezing the midpoint of the belt with moderate pressure (about 5 pounds). The resulting deflection should be about 1/4". If it isn’t, it will be necessary to loosen the motor mount bolts and slide the motor to either add or subtract tension from the belt.

Your combination sander is equipped with shield- ed and pre-lubricated ball bearings and require no lubrication for the life of the bearings. All bear- ings are common sizes and are readily available from a local bearing supply house or our Service Department.

Table

The working table and other non-painted sur- faces on the Model G5049Z should be protected against rust and pitting. Wiping the sander clean after every use ensures that sawdust isn’t allowed to trap moisture against bare metal sur- faces.

Some woodworkers recommend using automo- tive paste wax on exposed steel and cast iron surfaces. The wax provides a layer of protection, as well as reducing friction between lumber and the table. Avoid waxes that contain silicone or other synthetic ingredients. These materials can find their way into lumber that’s being sanded and can make staining and finishing difficult. If you use paste wax, make sure that it’s 100% Carnauba wax.
