Unpacking Your Tool
• Carefully unpack and inspect your tool. Fully familiarise yourself with all its features and functions
• Ensure that all parts of the tool are present and in good condition. If any parts are missing or
damaged, have such parts replaced before attempting to use this tool
Before Use
IMPORTANT: Before first use and after every 6 hours (approx.) of use, fill the gearbox cavity with
gearbox grease. A Pot of Grease (13) is supplied for initial use. See 'Gearbox Maintenance' for
application guidance
• Always check that there is sufficient grease in the gearbox cavity before using the drill
Operation
SDS Plus Chuck Operation
Note: The SDS Plus system allows the bit to move slightly within the chuck when inserted correctly.
The SDS Plus drill or chisel bit does not lock in position like a conventional chuck.
• To fit a bit to the machine, first grease the tail end of the bit. The Pot of Grease (13) supplied is
suitable for this. Pull back the Chuck Protective Cover (2) and hold. Push and rotate the bit into the
SDS Plus Chuck (1), as far as it will go. Release the chuck cover
8
• The bit should now be locked into the machine. Check by pulling the bit. If the bit can be removed,
repeat the above procedure until the bit is held securely
• To remove a bit from the chuck, pull the Chuck Protective Cover back and hold. The bit can then
be removed from the drill
Note: The Dust Guard (10) should be used by fitting to the drill or chisel bit to prevent debris and
dust entering the chuck. This is especially important when the drill is used at a raised angle when
working on walls or ceilings. For larger drill or chisel bits it may need to be fitted before the bit is
inserted in the chuck.
Hammer Selection
• The drill can be used in either hammer drill mode (for masonry work) or conventional rotary drill
mode (for wood, metal etc)
• To select hammer drilling mode, rotate the Hammer Selection Switch (6) to the left
• To select rotary drilling mode, rotate the Hammer Selection Switch to the right
• Do not attempt to move the Hammer Selection Switch whilst the drill is running
• Do not attempt to run the drill with the Hammer Selection Switch in a mid position
Rotation Selection
• The drill can be used in either rotation mode (for drilling), or roto-stop mode (for chiselling)
• To select rotation mode, twist the Rotation Selection Switch (3) to the left
• To select roto-stop mode, twist the Rotation Selection Switch to the right
• Do not attempt to move the Rotation Selection Switch whilst the drill is running
• Do not attempt to run the drill with the Rotation Selection Switch in a mid position
Depth Stop
1. To fit the Depth Stop (11) , loosen the Auxiliary Handle (8) by turning the handle grip anti-
clockwise
2. Lift the Auxiliary Handle up to a horizontal position
3. Insert the Depth Stop into the Depth Stop Mounting (9) in the Auxiliary Handle
4. Rotate the handle grip clockwise to re-tighten which will secure the Depth Stop and the Auxiliary
Handle position
Auxiliary Handle
• The Auxiliary Handle (8) should always be used when drilling
• Always hold the drill firmly using both hands
• The Auxiliary Handle position can be adjusted to best suit the work to be performed
On/Off Trigger Switch
• To start the drill, squeeze the On/Off Trigger (5)
• To stop the drill, release the On/Off Trigger (5)
CAUTION: The drill is not designed to be permanently switched on and there is no lock-on feature.
Do not attempt to improvise such a feature.
WARNING: This is a single-speed drill without variable speed adjustment. Any drill bit or core drill
that states a maximum rotation speed of less than 800rpm must not be used.
Drilling Concrete
• Using hammer drill mode and rotation 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
drill bit size is within the maximum capacity of the drill
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
• B e 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.
