Charging the Tool
The Cordless Rotary Tool is not fully charged. The tool
is equipped with a removable battery pack. Be sure to
charge pack prior to initial use. For best results on first
charge, charge pack overnight.
To charge the tool:
1. Put the switch in the “OFF” position.
2. Squeeze release tabs on both sides of battery pack,
and remove pack from back of tool as shown on page 9.
3. Align exterior shape of battery pack with exterior
shape of charger, squeeze release tabs, insert battery
pack into charger as shown and release pressure on
tabs so it locks in place.
4. Plug charger into the power source. The green L.E.D.
light indicates connection has been made and the
battery pack is charging. The LED light will remain lit
even after charging is complete. Under normal usage
the tool normally requires 3 hours charging time to
reach full capacity.
5. When charging is completed, squeeze release tabs on
battery pack and remove pack from charger.
6. Align exterior shape of battery pack with exterior
shape of the housing of tool as shown. Squeeze release
tabs, insert battery pack into back of tool, and release
pressure on tabs so it locks in place.
Important Charging Notes
If you anticipate long periods of non-use for your tool
it's best to unplug your charger and battery pack from
its power source. Unplugging the charger will extend
the life expectancy of the charger and battery pack.
The battery pack accepts only about 80% of its maxi-
mum charge capacity with its first charge; or, after pro-
longed storage it will also require additional time on the
first charge. However, after several charge and dis-
charge cycles, the batteries should be up to full charge
capacity and delivering maximum performance.
Operation Instructions
Introduction
The Cordless Rotary Tool is a handful of high-speed
power. It serves as a carver, a grinder, polisher, sander,
cutter, power brush, drill and more.
Your Cordless Rotary Tool has a small, powerful electric
motor, is comfortable in the hand, and is made to accept
a large variety of accessories including abrasive wheels,
drill bits, wire brushes, polishers, engraving cutters,
router bits, and cutting wheels. Accessories come in a
variety of shapes and permit you to do a number of
different jobs. As you become familiar with the range of
accessories and their uses, you will learn just how
versatile your Cordless Rotary Tool is. You’ll see dozens
of uses you hadn’t thought of before now.
The real secret of the Cordless Rotary Tool is its speed.
To understand the advantages of its high speed, you
have to know that the standard portable electric drill
runs at speeds up to 2,800 revolutions per minute. The
typical electric drill is a low-speed, high torque tool; the
Cordless Rotary Tool is just the opposite — a high-
speed, low torque tool. The chief difference to the user
is that in the high speed tools, the speed combined with
the accessory mounted in the collet does the work. You
don’t apply pressure to the tool, but simply hold and
guide it. In the low speed tools, you not only guide the
tool, but also apply pressure to it, as you do, for example,
when drilling a hole.
It is this high speed, along with its compact size and
wide variety of special accessories, that makes your
Cordless Rotary Tool different from other power tools.
The speed enables it to do jobs low speed tools cannot
do, such as cutting hardened steel, engraving glass, etc.
Getting the most out of your Cordless Rotary Tool is a
matter of learning how to let this speed work for you.
