1. The electronic speed control operates only when the
variable speed trigger switch
4
is fully depressed.
2. The effect of electronic speed control is much easier to
observe at lower speed settings (2600 OPM and below),
than at high speeds. As the tool approaches 3000 OPM,
the effect is considerably less dramatic.
Keep in mind that, with a conventional polisher running at
a typical no-load speed of 2400 OPM, the tool slows down
to about 2000 OPM under a polishing load. Your polisher
will continue to run at 2400 OPM (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. A, E)
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 random orbit 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. A, E). 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
Variable Speed Trigger Switch (Fig. A)
These tools are equipped with a variable speed trigger
switch that permits speed control from 0 to 5500 OPM.
To turn the tool on, squeeze the variable speed trigger
switch
4
shown in Figure A until the tool starts to run. The
farther you depress the trigger, the faster it will operate.
Releasing the trigger turns the tool off.
Use lower speeds for applying compounds, and higher
speeds for polishing. Use the highest speed (fully depress
trigger) for buffing the car to a final lustre.
The tool can be locked on for continuous use by squeezing
the trigger switch fully and depressing the lock button
8
shown in Figure A. Hold the lock button in as you gently
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. Do not insert the battery
into the tool with the switch in the locked-on condition.
Make sure the trigger is not depressed when inserting the
battery into the tool.
The variable speed trigger switch
4
has a no-volt release
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
3
to the desired setting.
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
3
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 2000–5500 OPM and the variable speed switch
will then control tool speed from zero to the wheel setting.
For example: A control wheel setting of 2200 OPM will allow
the variable speed switch to operate the tool between zero
and 2200 OPM, depending on how far the trigger switch is
depressed. A wheel setting of 2000 OPM would allow the
switch to operate the tool from zero to 2000 OPM.
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 OPM, as in
the example above, the tool will maintain 2200 OPM, as it
is loaded.
It is important to remember two things about electronic
speed control:
