Torque Adjustment
• To select the desired torque level to screw drive, turn the torque
regulator until it matches the corresponding number with the upper
mark:
From 1 to 3 for small screws,
From 4 to 7 for screws on soft materials,
From 8 to 11 for screws on soft and hard material,
From 12 to 15 for screws on hard wood,
On 16 to 18, for larger screws.
CAUTION The torque level needed depends on the type of screw
to be used and the material to work with. When in doubt, use the lower
torque and increase gradually until getting the right one. An adequate
torque prevents damaging the tool.
Turn ON and Operation Control
• With the switch, you can select the right speed for each job.
The more you press the switch, the faster the drill will run.
• The switch is also set up with a braking function. Once
releasing the trigger, the drill will immediately stop and can
be used as a manual screwdriver to give an extra turn to a
screw.
Screwing and Unscrewing
• We recommend to first bore a "pilot orifice", slightly
longer and just narrower than the screw to insert. The
pilot orifice will act as guide to introduce the screw and will
make it easier to tighten. When a screw is set close to the
work piece edge, a pilot orifice will also help prevent the
wood from breaking apart.
• Use the type of drill for each screw head to prevent the
screw to protrude out of the surface.
• If the insertion of a screw turns difficult, remove it and try
drilling a slightly longer or wider orifice. However, keep in
mind there shall be enough material to hold the screw.
When restarting the drilling operation in a previously made
orifice, start screwing by hand. If still hard to screw (like in
the case with very hard woods), try using some lubricant
like soap. Liquid soap is the most useful.
• Always apply enough pressure on the drill to prevent the
head from sliding. It is easy the screw head gets damaged
making it difficult to insert completely or even remove it.
Additional Recommendations
• Use the speed adequate for each job. Do not try to drill in low speed or to screw in high speed.
• If the operation overloads the drill, extract it and repeat the operation this time applying less force.
• Use low speed to start perforations where there is no support point, over plastic or metal or when screwing on ceramic
or any application requiring a high torque. Use high speed to drill on wood and when using polishing accessories. To gain
the maximum useful life from your drill, use a variable speed control.

Screwing
• When trying to drill orifices with a large diameter, is
better to start with a slim bit and then replace it with one of
the required size. This prevents the drill to overheat.
• When drilling deep orifices, remove the bit only a little bit
and regularly while drilling so that shavings can be expelled
adequately out of the orifice.
CAUTION • If the bit gets stuck, release the switch
immediately to prevent permanent damage in the tool. Try
unblocking the bit reversing the direction of the operation.
Keep the drill aligned with regards to the orifice. Ideally,
the bit shall always penetrate perpendicularly into the work
piece. If the angle is changed during the drilling process,
the bit could break and block the orifice or cause personal
injuries.
