• If debris blocks the drill hole, reduce the pressure, run the drill slowly and
remove the bit from the hole. Repeat until the hole is cleared
Chiselling
WARNING: An SDS Plus Drill with a fitted chisel is not a viable alternative to
a professional breaker. Do not use this tool for breaking up patios, paths or other
areas of thick concrete. Always consider the force required to break up different
materials. If the chisel fails to break the chosen material, stop using it immediately.
The chisel tip and internal parts of the SDS drill will become damaged if the chisel
tip strikes a surface that it cannot break or requires repeated strikes at the same
point to break.
• Using hammer drill mode and roto-stop mode, apply pressure to the rear of the
drill in line with the chisel
• Be aware that when chiselling, there is a high risk of chips and other waste,
being ejected from the workpiece
Safety Clutch
In the event that a drill bit or core drill becomes locked in the workpiece while
operating and cannot rotate, or is forced to operate at a very low rotational speed,
the safety clutch will disengage the drive.
In this event quickly release the trigger which will help prevent injury and reduce
wear on the safety-clutch mechanism.
After the safety clutch has activated, completely recheck all equipment is correctly
set up and the drill bit or core drill is not badly worn or damaged. It may be
necessary to work at a slower rate. In some instances you may find the drill is not
suitable especially if using large core drills.
WARNING: Do not rely on the safety clutch. Always configure your equipment for
safe use so that the safety clutch will not operate.
Drilling Wood and Metal
Attaching the Keyed Chuck
A conventional 13mm (1/2") keyed chuck is supplied with this product.
To attach the Keyed Chuck (18):
1. Screw the SDS Plus Arbor (16) to the Keyed Chuck (18) (Fig. I)
2. Screw the Arbor Screw (20) through the Chuck into the Arbor (16) (Fig. II)
Note: the Arbor Screw has a left handed thread and therefore will tighten by
turning anticlockwise and slacken turning clockwise.
3. Insert the chuck assembly into the SDS Plus Chuck (1)
4. Insert a conventional drill bit for either wood or metal into the Chuck and tighten
the Chuck with the Chuck Key (17). See specification for maximum drilling
capacity in wood and metal
CAUTION: The keyed chuck is not for masonry bits and will be damaged if used in
hammer mode. Always use SDS Plus masonry bits fitted directly into the SDS Plus
Chuck for masonry use.
Drilling Wood
• Use rotary drill mode only
• Ensure drill bits are suitable for wood and are within the maximum capacity
of this drill
Drilling Metal
• Use rotary drill mode only
• To ensure accuracy, mark the intended hole position using a hammer and
centre punch
• Ensure drill bits are suitable for the grade of metal being drilled, and are within
the maximum capacity of the drill
• To ensure efficient cutting, and prolong drill bit life, use a suitable lubricant/
cutting fluid
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 of
the drill then reduce the pressure. Overloading the drill will reduce its service life.
• As the drill 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 auxiliary handle, and use sharp drill bits
• Always ensure 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.
Gearbox Maintenance
After every 6 hours of use (approx.), the gearbox must be regreased
1. Use the Gearbox Pin Spanner (12) to unscrew the Gearbox Cover (4)
2. Use a spatula or similar instrument to apply grease into the gearbox cavity
until it is full
3. Be careful not to scratch or damage the mechanism
4. Replace the Gearbox Cover (4)
NOTES:
• A Pot of Grease (13) is supplied for the first few regreases but additional grease
will be required. When purchasing additional grease, select a general purpose
lithium-based grease
• Do not over-tighten the gearbox cover or overfill the gearbox with grease
• If you are not sure how to change the grease or what grease to use, take your
drill to your dealer or the nearest authorised service centre and ask a qualified
person to replace the grease
Cleaning
• Keep your machine clean at all times. Dirt and dust will cause internal parts
to wear quickly, shortening 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
• This product is supplied with a spare pair of Brushes (19)
• 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 Cover (7) and the cover on
the opposite side. The worn brushes can then be withdrawn, and replaced
with new. Always replace worn brushes in pairs. Refit the brush access covers.
Alternatively, have the machine serviced at an authorised service centre
Storage
After use, return the drill and accessories to the supplied case and store in a
damp-free environment, out of reach of children.
