recommend you clean and polish a test section on a flat area of the
car first. From this test section, you can judge the strength or
cleaning action of your power polish.
Remember, all power polish is not the same. Different brands will react
differently on various painted surfaces. Also, you are now using a power
polisher with power polish. This is entirely different from any hand
application which you may have done before. Wash the car before
power polishing it. Washing will remove loose dirt, scum, road salt, etc.
which could act as an abrasive and damage paint. Loose dirt, etc. will
also clog the polishing pad and you will have to clean it more often.
Without turning the tool on, grasp the handles of the tool and pick it
up. Keep the tool away from your body and turn the switch on. Make
sure you have a firm grip on the handles and operate the tool freely
without forced effort or unnecessary pressure. The side handle can
be easily changed to either side of the tool for left-handed or right-
handed operation.
NOTE: The high speed rubbing action of the polishing bonnet upon the
surface of an automobile can build a static charge on the metal portions
of this tool. This can result in a sensation of a very short mild electric shock
when the metal area of the tool is touched, and will be more noticeable on
days when the humidity is low. This is a harmless phenomenon but you
are invited to bring the tool to a Snap-on service center where it can be
checked to assure that no electrical malfunction is present.
Sanding Application (ET1490 ONLY)
ATTACHING AND REMOVING ABRASIVE DISCS
(FIGURES 6, 7, AND 8)
TURN OFF TOOL AND DISCONNECT FROM POWER SUPPLY.
To attach the sanding disc, push the hub of the clamp washer through
the center of the sanding and phenolic discs, as far as it will go, and
also through the backing pad. Engage the clamp washer threads on
the tool spindle and thread assembly clockwise, completely down on
the spindle. Hold the spindle from rotating by engaging the spindle
lock button.
To remove the abrasive disc, use a cloth or glove to protect your
hand. Turn the disc assembly counterclockwise (Figure 8). Hold the
spindle from rotating by engaging the spindle lock button.
Sanding (ET1490 ONLY)
(See Figure 9) When using an abrasive disc, hold the tool so that an
angle of 10˚ to 15˚ exists between the disc and the work. If only the
outer edge of the sanding disc is used, a rough cut will result. If the
sanding disc is pressed flat against the work, the sanding action will
be irregular and bumpy, and the tool will be difficult to control.
Cleaning
Blowing dust, polishing bonnet lint, and grit out of the motor housing
using compressed air is a necessary regular maintenance procedure.
Dust and grit containing metal particles often accumulate on interior
surfaces could create an electrical shock hazard if not frequently
cleaned out.
CAUTION: Never use solvents or other harsh chemicals for
cleaning the non-metallic parts of the tool. Use clean, dry rag only.
Lubrication
Snap-on tools are properly lubricated at the factory and are ready
for use. Tools should be relubricated regularly every sixty days to six
months, depending on usage. (Tools used constantly on production
or heavy-duty jobs and tools exposed to heat may require more
frequent lubrication.) This lubrication should only be attempted by
trained power tool repairpersons such as those at Snap-on service
centers or other authorized service locations.
Motor Brushes
Be sure tool is unplugged before inspecting brushes. Carbon brushes
