• 

Begin drilling at a very low speed to prevent the bit from slipping off the starting 

point. Increase the speed as the drill bit bites into the material.

• 

When drilling through holes, place a block of wood behind the work-piece to 

prevent ragged or splintered edges on the back side of the hole.

• 

Do not lock the trigger in the “on” position when the drill may need to be 

stopped suddenly.

Masonry drilling

• 

For maximum performance use tungsten carbide-tipped masonry impact bits 

when drilling holes in brick, tile, concrete, etc.

• 

Push the drilling mode selector to impact mode

• 

Apply light pressure and medium speed for best results in brick.

• 

Apply additional pressure and high speed for hard materials such as concrete.

• 

When drilling in tile, practice on a scrap piece to determine the best speed and 

pressure.

CAUTION!

Always be sure that the tool is switched off and unplugged before attempting to 

perform inspection or maintenance.

• 

Inspecting the mounting screws regularly inspect all mounting screws and ensure 

that they are properly tightened.

• 

Regularly clean the tool’s air vents with compressed dry air. Do not attempt to 

clean by inserting pointed objects through openings.

CAUTION!

 Certain cleaning agents and solvents damage plastic parts. Some of 

these are: gasoline, carbon tetrachloride, chlorinated cleaning solvents, ammonia 

and household detergents that contain ammonia.

• 

The brushes should be checked periodically and worn-out brushes should be 

replaced in time.

WARNING!

If any of the following events occur during normal operation, the power supply 

should be shut off at once and tool thoroughly inspected by a qualified person 

and repaired if necessary:

• 

The rotating parts get stuck or speed drops abnormally low. 

• 

The tool shakes abnormal accompanied by some unusual noise

• 

The motor housing gets abnormal hot.

• 

Heavy sparks occur around the motor area.

1.  Siempre  tome  la  herramienta  por  una  manubrio  aislada  cuando  deba  utilizarla 

para  cortar  por  un  lugar  donde  pueda  haber  cables  escondidos  o  donde  pueda 

entrar en contacto con su propio cable. Si las partes metálicas de la herramienta 

entran en contacto con un cable, el usuario puede recibir un choque eléctrico.

2.  Siempre  utilice  una  manubrio  auxiliar  para  tener  el  máximo  control  sobre  los 

rebotes y la fuerza de respuesta.

3. Utilice guantes gruesos. Siempre limite el tiempo de exposición, haga períodos 

de descanso frecuentes.

4. Asegure el material que va a taladrar. Nunca lo sostenga en sus manos o entre las 

piernas. Los soportes inestables pueden hacer que la broca se salga de control y 

ocasiones daños.

5. Coloque el cable en un lugar alejado de las partes movibles. No enrolle el cable 

en su brazo o en su muñeca ya que si pierde el control podría ocasionarse daño.

6. Si la broca se atasca en la pieza de trabajo, suelte el gatillo de inmediato, cambie 

la dirección de rotación y presione el gatillo cuidadosamente para poder destrabar 

la broca. El cuerpo del taladro tiende a girar en la dirección opuesta que la 

dirección de la broca.

7. No coloque las manos cerca del mandril giratorio o de la broca.

8.  No opere una herramienta eléctrica en ambiente explosivos, como en lugares 

donde haya líquidos inflamables, gases o polvo. Las herramientas eléctricas hacen 

chispas las cuales podrían encender fuego con el polvo o el humo.

9. No toque la broca después de terminar de utilizarla ya que estará muy caliente.

10. Solo utilice brocas en buen estado.

11. Mantenga las manos alejadas debajo de la pieza de trabajo.

12. Verifique frecuentemente que las tuercas, los tornillos y otras partes se encuen-

tren bien ajustadas.

13. Los trapos, las cuerdas y los cables no deben estar cerca del área de trabajo.

14. Después de un tiempo de uso, las brochas de carbón se gastarán hasta un punto 

en que empezarán a sacar más y más chispas. Es en este momento en que debe 

cambiar las brochas o el motor se dañará.
