Start Up

General remarks for using the battery

• Hold the handle firmly with one hand and with the other 

hand turn the tip of the chuck counter clockwise, so that 

the jaws loosen.

• Insert the bit until it stops or remove it whichever the 

situation.

• Hold the Chuck base firmly with one hand and with the 

other hand turn the tip of the cuck clockwise to secure the 

bit.

ENGLISH

• To bore and screw release the switch and and press the direction 

button on the side where marks point towards the chuck.

• To reverse the turn, and unscrew press it on the other side.

• The drill switch will get blocked if the button sits in the middle.

                          • The first time you turn on the 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 rotation direction while the drill is running.

• 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.

Speed selection

• To bore concrete, tiled floor or materials similarly hard, turn the 

function selection collar into the IMPACT (        ) position. The bit will 

strike and rotate at the same time onto the material.

• To bore metal or plastic turn the function selection collar into the 

DRILL (        ) position to make the bit rotate against the material.

• For screw / unscrew turn the function selection collar to this position 

(       ) so the bit turns over the screw for better control.

                             • 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.

WARNING

The battery is shipped NOT CHARGED.  It is necessary to charge the battery approximately 6 hours 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.
