Start Up
Battery use
The battery is shipped NOT CHARGED. It is necessary to charge the battery approximately 1 hour before being able to use it.
The normal charge is 32 °F to 113 °F. When not in this level the charge automatically stops until reaching the right temperature.
The normal temperature for discharge / work is 32 °F to 167 °F. If 167 °F are exceeded, the electronic control stops the tool
energy until the temperature reaches the temperature optimum new level. When the battery is below the normal tension while
working the tool stops working. Give the tool 15 minutes rest. In warm weather or after a long period of work the battery will get
too hot to recharge. Allow the battery to cool down before trying to charge again.
Bits or adaptors assembly
• Using one hand, hold firmly the handle and with your
other hand loosen the base turning in a counterclockwise
direction, to loosen the jaws.
• Insert the bit until it stops or remove it whichever the
situation.
• Turn the base clockwise to fasten the bit.
Direction of rotation
• To rotate forward release the trigger and press the direction button on the
side where arrows point towards the chuck.
• To reverse the turn, press it on the other side.
• The hammer drill will get blocked if the button sits in the middle.
CAUTION • The first time you turn on the hammer drill and after
reversing rotation you might hear a click. This in normal and does not
represent a problem.
• To prevent damaging the tool, never reverse the
CAUTION
rotation direction while the hammer drill is running.
Speed selection
• The two speeds in the drill work in a similar manner to those
used in cars.
• Low speed (1) will give a lot of torque (torsion power). Use this
speed when starting to drill large orifices, be it wood or metal. This
will prevent the bit to get stuck.
• High speed (2) has a reduced torque but lets the drill operate
with higher revolutions per minute, that make the tool when in
the drill function to bore faster lean metal or wood.
Change from hammer drill to drill
• To bore concrete, tiled floor or materials similarly hard, turn the torque
regulator into the IMPACT (
at the same time onto the material.
• To bore metal or plastic turn the impact-rotation selector chuck into the
DRILL (
matching with the top mark) position to make the bit rotate
against the material.
WARNING
• Do not try to drill metal, wood or plastic with the
hammer drill in the IMPACT mode. Otherwise the tool efficiency would
diminish and the bit tip will get damaged.
