Unpacking Your Tool
• Carefully unpack and inspect your tool. 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.
Operating Instructions
Side handle
• The Side Handle (10) should always be used when drilling
• The side handle can be adjusted to best suit the work to be performed
• To adjust the side handle, rotate the grip anti-clockwise, this will loosen the handle
assembly. Move the side handle to the required position, and secure by turning
clockwise
Operating the SDS Plus chuck
Note: Unlike a conventional chuck the SDS Plus chuck system allows the bit to move
slightly within the chuck when inserted correctly. The bit can move slightly forward and
backward. This is normal and not a fault.
• Always grease the tail end of SDS bits. A general purpose lithium-based grease can be
used. Bits should always be freshly greased, and free from dirt and dust before use. Pull
back the chuck collar and hold. Push and rotate the bit into the SDS Plus Chuck (4), as
far as it will go. Release the chuck collar
• The bit should now be locked into the machine. Check this by pulling the bit. If the bit
can be removed, repeat the above procedure until secure
• To remove a bit from the chuck, pull the chuck collar back, and hold. The bit can then be
removed from the machine
WARNING: This power drill does not feature a rota-stop mode to allow hammer action
without rotating and is therefore not suitable for chisels or other bits that require no
rotation. Do not attempt to use such bits with this power tool.
WARNING: Never fit any drill bit with a maximum speed lower than the maximum no load
speed of this drill. Although this drill features a variable speed trigger action do not attempt
to operate low-speed drill bits or accessories by only partially holding in the trigger. Those
accessories are designed for drills that can pre-set their maximum speed before use or
operate permanently below the speed of the bit or accessory.
On/off trigger
• Always hold the drill firmly, using both hands
• To start the drill, squeeze the On/Off Trigger (8)
• To stop the drill, release the on/off trigger
• Whilst drilling, the on/off trigger can be locked by pressing the
Lock On Switch (9)
• To release the lock on switch, squeeze the on/off trigger again
• The speed of the drill is variable by how far the trigger is pressed but the lock on switch
can only function while the drill operates at maximum speed
Hammer selection
• The drill can be used in either rotary or rotary hammer mode
• To select rotary hammer mode, rotate the Hammer Switch (7) down, to the 'I' position
• To select rotary drilling mode, rotate the hammer switch up, to the '0' position
• Do not attempt to move the hammer selector whilst the drill is running
• Do not attempt to run the drill with the hammer selector in mid position
Using the 3-Jaw Chuck
• The drill is supplied with a 3-Jaw Chuck (2) and Chuck SDS Plus Arbor (3). This allows
conventional drill bits to be used with your SDS drill for drilling metal, wood and other
materials that do not require hammer action
• The 3-jaw chuck is a screw fit onto the arbor. Remove the locking screw from the arbor
by turning clockwise. The chuck can be secured on the arbor by inserting the locking
screw through the body of the chuck and it secures by turning anti-clockwise
• The chuck SDS Plus arbor fits into the SDS Plus chuck in the same way as an SDS
drill bit
NOTE: Due to the SDS Plus chuck mounting, the 3-jaw chuck will have a small amount of
forward and backward movement in use. It should not affect normal operation for most
drilling but be aware that when you use the power drill there may be a small amount of
travel after the drill bit contacts the surface before the drill is effective and starts drilling.
Also when removing the drill bit from the surface there will be a small amount of travel of
the drill body before the drill bit starts to be removed.
WARNING: Do not attempt to use hammer mode with the 3-jaw chuck fitted to the drill.
This could result in severe damage to the chuck and will invalidate your guarantee. Only
use SDS Plus masonry bits fitted to the SDS Plus chuck for masonry work.
Drilling concrete
• Insert a suitable masonry SDS Plus drill bit into the SDS Plus Chuck (4)
• Using rotary 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 drill bit diameter is within the maximum capacity of the drill and that the
maximum speed of the drill bit equals or exceeds the maximum no load speed of the
drill (see specifications)
• Do not apply too much 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 with the 3-Jaw Chuck (2) fitted
• Ensure that the drill bit diameter is within the maximum capacity of the drill and that the
maximum speed of the drill bit equals or exceeds the maximum no load speed of the
drill (see specifications)
Drilling metal
• To ensure accuracy, mark the intended hole position using a hammer and centre punch
• Use rotary drill mode only with the 3-Jaw Chuck (2) fitted
• Ensure that drill bits are suitable for the grade of metal being drilled and that the
drill bit diameter is within the maximum capacity of the drill and that the maximum
speed of the drill bit equals or exceeds the maximum no load speed of the drill (see
specifications)
• To ensure efficient cutting, and prolong drill bit life, use a suitable lubricant or cutting
fluid, and drill at moderate speed
Using the depth stop feature
• This feature can be used to ensure holes are drilled to a required depth
• Insert the Depth Stop Rod (6) into the Depth Stop Clamp (5)
• Slide it forwards until it is aligned with the tip of the drill bit
• Slide the depth stop rod back towards the rear of the drill by the required distance (the
depth of hole required)
• Tighten the depth stop clamp
• Now when drilling into a flat surface such as a wall, the tip of the depth stop rod
touching the surface will indicate when the required depth of the hole is drilled
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, it may catch or 'snag'. This can cause the machine
to suddenly 'kick'. To prevent any possibility of injury, always hold the drill securely by
using the side handle. Also, always 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
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 dis-engage 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 operated, 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.
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, 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
• Over time the carbon brushes inside the motor may become worn. Excessively worn
brushes may cause loss of power, intermittent failure or visible sparking
• If you suspect that the brushes may be worn, 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 correct way to
dispose of tools
