SECTION 7: MAINTENANCE
General
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
1
be about
/
". If it isn't, it will be necessary to
4
loosen the motor mount bolts and slide the motor
to either add or subtract tension from the belt.

Lubrication
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.
