• If the safety clutch operates during use, quickly release the trigger and remove the core drill or
bit from the masonry surface being drilled.
Do not continue work until the cause of the safety clutch
operating is understood
• Do not operate SDS drills whilst up a ladder or in any location where there is a risk of falling. SDS
drills are heavy and produce strong vibration and high torque in use
• Wear suitable protective anti-vibration gloves that are non-fabric or coated fabric to prevent
loose strands of material catching in the rotating drill bit. Discard gloves immediately if material is
visibly frayed
• Drilling can produce large volumes of dust and debris that may be toxic. Wear respiratory protection
suitable for the work being undertaken. A minimum rating of FFP2 is recommended
• SDS drills produce high volumes of noise and suitable ear protection must be worn at all times
while operating the tool
• SDS drills produce a very high level of vibration when operating in hammer or chisel mode.
Frequent breaks are advised
• Only use SDS Chisels or Points with SDS drills that can disengage rotary drilling mode
• Use metal and voltage detectors to locate concealed electric, water or gas lines.
Avoid touching live
components or conductors
• Extension cable reels used with this tool must be completely unwound. Minimum conductor cross
section: 1.25mm2
• Extension reels used outside should be designed for outdoor use and should feature
water-protected sockets and correct cable insulation
• When using an SDS drill outdoors, an RCD device must be used either by connecting to a socket
which incorporates an RCD, or through use of an inline RCD
• Ensure that the chisel or drill bit is securely fixed in the chuck before operating the tool. Insecure
drill bits can be ejected from the machine, causing a hazard
• Ensure lighting is adequate
• Use both hands when operating this tool
• Do not place pressure on the tool.
To do so could shorten its service life
• Drill bits become hot during operation. Allow to cool prior to handling
• If you are interrupted when operating the drill, complete the process and switch off before
diverting your attention elsewhere
• Always disconnect the SDS drill from the electric supply before changing a chisel or drill bit
• Examine the SDS chuck regularly for signs of wear or damage.
Have damaged parts repaired by a
qualified service centre

• On completion of the work, disconnect the tool from the power source and remove the chisel/bit
from the machine
• Periodically check all nuts, bolts and other fixings and tighten where necessary
• Visibly check the tool after use, especially the power cable, which can be damaged by sharp
masonry
• Always fit the dust guard to the bit in use to prevent damage from debris entering the SDS chuck
• If operating the tool causes discomfort in any way, stop immediately and review your method
of use
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 material, stop using it
immediately. Striking a surface the chisel cannot break, or carrying out repeated strikes at the same point, will
damage the chisel tip and the internal
Important safety devices! Ensure correct function, maintain in accordance with instructions and DO NOT
disable!
