ENGLISH    (Original instructions)
Setting the drilling depth (fig.B)
•  Slacken the side handle (7) by turning the grip counter 
clockwise.
•  Set the depth stop(6) to the desired position. The 
maximum drilling depth is equal to the distance between 
the tip of the drill bit and the front end of the depth stop.
•  Tighten the side handle by turning the grip clockwise.
Switching on and off
•  To switch the tool on, press the variable speed switch(1). 
The tool speed depends on how far you press the 
switch. As a general rule, use low speeds for large 
diameter drill bits and high speeds for smaller diameter 
drill bits.
•  For continuous operation, press the lock-on button (2) 
and release the variable speed switch. This option is 
available only at full speed in both forward and reverse 
modes.
•  To switch the tllo off, release the variable speed switch. 
To switch the tool off when in continuous operation, 
press the variable speed switch again and release it.
•  Based on the different applications, turn around the 
speed dial(11) to control the maximum speed.
Drilling in metal
Start drilling with slow speed and increase to full power while 
applying firm pressure on the tool. A smooth even flow of 
metal chips indicates the proper drilling rate. Use a cutting 
lubricant when drilling metals. The exceptions are cast iron 
and brass which should be drilled dry.
NOTE: Large [5/16” (8 mm) to 1/2” (13 mm)] holes in steel 
can be made easier if a pilot hole [5/32” (4 mm) to 3/16” (5 
mm)] is drilled first.
Drilling in wood
Start drilling with slow speed and increase to full power while 
applying firm pressure on the tool. Holes in wood can be 
made with the same twist drills used for metal. These bits 
may overheat unless pulled out frequently to clear chips 
from the flutes. Work that is apt to splinter should be backed 
up with a block of wood.
Drilling in masonry
When drilling in masonry, use carbide-tipped bits rated for 
Impact drilling and be certain that the bits are sharp. Use a 
constant and firm force on the tool to drill most effectively. A 
smooth, even flow of dust indicates the proper drilling rate.
Screwdriving
Select forward or reverse rotation.
