release the trigger switch. The tool will continue to run. To
turn the tool off from a locked-on position, squeeze and
release the trigger switch once.
The variable speed trigger switch
function. In the event of a dead battery or other unexpected
shut down, the trigger switch needs to be cycled (depress
the trigger switch, release, then depress again) to restart
the tool.
Speed Control Wheel (Fig. A)
The maximum speed of your tool can be changed by
rotating the speed control wheel
The wheel incorporates detents to prevent inadvertent
wheel movement and to facilitate speed selection. For
added versatility, the trigger switch may be locked in its full
on position and tool speed changed by means of the speed
control wheel

alone.
The electronic speed control not only lets you select the
speed to suit the job, but also helps to maintain that speed
as you load the tool by pressing down. It's this feature,
coupled with the variable speed trigger switch, that make
this tool such a value.
The speed control wheel
3
can be set for any speed
between 800 and 2200 RPM and the variable speed switch
will then control tool speed from zero to the wheel setting.
For example: A control wheel setting of 2200 RPM will allow
the variable speed switch to operate the tool between zero
and 2200 RPM, depending on how far the trigger switch
is depressed. A wheel setting of 800 RPM would allow the
switch to operate the tool from zero to 800 RPM.
The electronic speed control feature comes into play
whenever the trigger switch is fully depressed and the tool
is running at the selected speed determined by the setting
of the control wheel. As you load the tool by pushing it
down on the work surface, (with the trigger fully depressed)
the electronic circuit inside the tool will compensate
for the loading and maintain the selected speed. If the
speed selected by the control wheel is 2200 RPM, as in
the example above, the tool will maintain 2200 RPM, as it
is loaded.
It is important to remember two things about electronic
speed control:
1. The electronic speed control operates only when the
variable speed trigger switch
2. The effect of electronic speed control is much easier to
observe at lower speed settings (1400 RPM and below),
than at high speeds. As the tool approaches 2000 RPM,
the effect is considerably less dramatic.
Keep in mind that, with a conventional polisher running at
a typical no-load speed of 2200 RPM, the tool slows down
to about 2000 RPM under a polishing load. Your polisher
will continue to run at 2200 RPM (or any speed you select
with the control wheel) as a load is applied. Since it doesn't
slow down, the speed may be greater than you're used to,
so some extra caution should be observed until you get the
"feel" of your polisher. If you feel the speed is too great, you
can, of course, slow the speed down with either the trigger
switch or the control wheel.

Polishing (Fig. F)
These instructions and suggestions are intended to
familiarize new operators in overall general operation of
power polishing. You will develop your own techniques
which will make the job easier and faster as you learn
power polishing.
•
You should use utmost care when power polishing
around or over sharp objects and contours of the car
body. It is very important to use the correct pressure
while polishing various sections of an automobile body.
For example, light pressure should be applied when
polishing over sharp edges of body panels, or over
edges of the rain gutter along the top.
•
Since everyone does not use the same type of power
polish, we 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 rotary polisher with power
polish which 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 (Fig. F). Keep the tool away from your
body and depress the trigger switch. 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
Mac Tools service center where it can be checked to assure
that no electrical malfunction is present.
MAINTENANCE
WARNING: To reduce the risk of serious personal
injury, turn unit off and remove the battery pack
before making any adjustments or removing/
installing attachments or accessories. An
accidental start-up can cause injury.
