DO NOT BLOCK VENT OPENINGS!
Tool Operation
1. Secure the material being drilled using vise or clamps
to make sure it does not move while drilling.
2. Select the appropriate bit for the task. (see applications
section below).
3. Always use sharp bits to avoid slipping or overstressing
the tool.
4. Use only enough steady pressure to allow the bit to
effectively cut. Do not use excessive pressure.
5. Select the appropriate application for the task (see
applications section below).
6. Select the appropriate speed for the task (see
applications section below).

7. Place the tip of the bit against the work piece before
starting the tool.
8. Apply firm pressure to the tool before starting and
during drilling. Too much pressure will slow the bit and
reduce drilling efficiency. Too little pressure will allow
the bit to slide or spin against the work piece, dulling
the bit and losing control.
9. Always start drilling or driving slowly, and gradually
increase speed as you go.
10. Find the right amount of pressure and speed to allow
the bit to do the work and produce a consistent chip.
11. If the tool begins to stall, reduce the amount of
pressure to allow the bit to regain speed.
12. Pull the bit out of the work piece multiple times while
drilling each hole to remove chips that can cause
binding.
13. Use backing material whenever possible to prevent
binding of the bit or distortion of the material upon
breakthrough.
14. If the bit binds in the work piece, reverse the tool to free
and remove the bit.
15. Always test the bit in a scrap piece to determine optimal
bit and settings for each application.
Fuel Gauge
The tool is equipped with a fuel gauge to indicate the
battery's state of charge. It is located on the left side of
the tool at the top of the handle. A round tri-color LED
changes color depending on state of charge. The gauge
is activated for three seconds at each trigger pull. The
following describes its function:
• LED IS GREEN - Battery is between 40% and 100%
charged
• LED IS YELLOW - Battery is between 25% and 40%
charged
• LED IS RED - Battery is between 0% and 25% charged
• LED IS FLASHING RED - Battery needs charging
immediately
