(Original instructions)
•  Wear ear protectors with impact drills.Exposure to noise 
can cause hearing loss.
•  Use auxiliary handles supplied with the tool. Loss of 
control can cause personal injury.
•  Hold power tool by insulated gripping surfaces, when 
performing an operation where the cutting accessory 
may contact hidden wiring or its own cord. Cutting 
accessory contacting a "live" wire may make exposed 
metal parts of the power tool "live" and shock the 
operator.
•  If operating a power tool in a damp location is 
unavoidable, use a residual current device (RCD) 
protected supply. Use of an RCD reduces the risk of 
electric shock.
Prior to operation
•  Insert the appropriate bit.
•  Mark the spot where the hole is to be drilled.
Proper Hand Position (fig. A, E)
Warning: To reduce the risk of serious personal 
injury, ALWAYS use proper hand position as 
shown.
Warning: To reduce the risk of serious personal 
injury, ALWAYS hold securely in anticipation of a 
sudden reaction.
Proper hand position requires one hand on the side handle 
(6), with the other hand on the main handle.
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.
•  For continuous operation, press the lock-on button (2) 
and release the variable speed switch. This option is 
available only at full speed.
•  To switch the tool off, release the variable speed switch. 
To switch the tool off when in continuous operation, 
press the variable speed switch once more 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.
Impact drilling (fig. A)
•  Select the Impact mode.
•  Press the switch (1).
Rotary drilling (fig. A)
•  Select the rotary drilling mode.
•  Proceed as described for Impact drilling.
