Hammer selection
• This drill can be used in three different modes, for different purposes:
Rotary drill:
• Rotary drill mode is suitable for working with wood, metal and plastics
• Align the Hammer Action Selector (4) with the
• Fit an appropriate drill bit into the chuck
Hammer drill:
• Hammer drill mode is suitable for working with brickwork, concrete
and other masonry
• Align the Hammer Action Selector (4) with the
• Fit an appropriate masonry drill bit into the chuck
Chisel:
• Chisel mode is suitable for working with brickwork, concrete and
other masonry
• Align the Hammer Action Selector (4) with the
• Fit an appropriate chisel bit into the chuck
Drilling concrete
• Using hammer drill mode, apply pressure to the rear of the drill, in line
with the drill bit
• For efficient drilling, it is advisable to use TCT (tungsten carbide tipped)
drill bits. Ensure that the bit size is within the maximum capacity of the
machine (see specifications)
• Do not apply excessive pressure. If debris blocks the drill hole, run the
drill slowly and remove the bit from the hole. Repeat until hole is cleared
Drilling wood
• Use rotary drilling mode only
• Ensure that drill bits are suitable for wood, and are within the maximum
capacity of this machine (see specifications above)
Drilling metal
• To ensure accuracy, mark the intended hole position using a hammer
and centre punch
• Use rotary drill mode only
• Ensure that drill bits are suitable for the grade of metal being drilled, and are
within the maximum capacity of the machine (see specifications above)
• To ensure efficient cutting, and prolong drill bit life, use a suitable
lubricant or cutting fluid, and drill at moderate speed
Chiselling
• Using chisel mode, apply pressure to the rear of the drill, in line with the
chisel bit
• Be aware that when chiselling there is a high risk of chips, and other
waste, being ejected from the work
Using the three jaw chuck accessory
• The drill is supplied with a 3 Jaw Chuck (7), and SDS Adaptor (8). This
allows conventional drill bits to be used with your SDS drill
• The SDS Adaptor (8) fits into the drill chuck in the same manner as an
SDS drill bit

• The 3 Jaw Chuck (7) is a screw fit onto the adaptor
• Do not attempt to use hammer mode with the 3 Jaw Chuck. This could
result in severe damage to your tool, and may invalidate your guarantee
Caution
• Applying excess pressure does not result in faster or more efficient
drilling. If the pressure applied to the drill has a noticeable effect on the
speed, reduce the pressure. Overloading the drill will reduce its service
life
• As the bit penetrates the material being drilled, it may 'catch' or 'snag'.
This can cause the machine to suddenly 'kick', to prevent any possibility
of injury always hold the drill securely, use the side handle, and use sharp
drill bits of the correct type
• Always ensure that material is secure. If appropriate use a vice or clamp
to hold the work, always keep two hands on the drill
Maintenance
WARNING: Always remove the plug from the mains power supply before
carrying out any maintenance/cleaning.
Cleaning
• Keep your machine clean at all times. Dirt and dust will cause internal
parts to wear quickly, and shorten the machine's service life. Clean the
body of your machine with a soft brush, or dry cloth. If available, use
clean, dry, compressed air to blow through the ventilation holes
Brushes
• Over time the carbon brushes inside the motor may become worn
• Excessively worn brushes may cause loss of power, intermittent failure,
or visible sparking
• To replace the brushes, remove the brush access plugs from both sides
of the machine. The worn brushes can then be withdrawn, and replaced
with new. Replace brush access plugs. Alternatively, have the machine
serviced at an authorised service centre
Disposal
• Do not dispose of power tools, or other waste electrical and electronic
equipment, with household waste
• Contact your local waste disposal authority for information on the proper
way to dispose of tools
