Do not overreach. Keep proper footing and balance at all times. This enables better control of
the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.
If devices are provided for the connection of dust extraction and collection facilities, ensure
that these are connected and properly used. Use of these devices can reduce dust-related
hazards.
POWER TOOL USE AND CARE
Do not force the power tool. Use the correct power tool for your application. The correct
power tool will do the job better and more safely at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot
be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or the battery pack from the power tool
before making any adjustments, changing accessories, or storing power tools. Such
preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with
the power tool or these instructions to operate the power tool.
Power tools are dangerous in
the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts
and any other condition that may affect the power tool’s operation. If damaged, have the
power tool repaired before use. Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
Use the power tool, accessories, tool bits, etc. in accordance with these instructions, taking
into account the working conditions and the work to be performed.
Use of the power tool for
operations different from those intended could result in a hazardous situation.
SERVICE
Have your power tool serviced by a qualified repair person using only identical replacement
parts. This will ensure that the safety of the power tool is maintained.
WORK AREA SAFETY
Keep the work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools create sparks, which may ignite the dust or fumes.
Keep children and bystanders away while operating a power tool. Distractions can cause you
to lose control.
ELECTRICAL SAFETY
Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any
adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets
will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will increase
the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool.
Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords
increase the risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use.
of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is unavoidable, use a ground-fault circuit
interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.
PERSONAL SAFETY
Stay alert, watch what you are doing and use common sense when operating a power tool.
Do not use a power tool while you are tired or under the influence of drugs, alcohol or
medication. A moment of inattention while operating power tools may result in serious personal
injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to
power source and/or battery pack, picking up or carrying the tool. Carrying power tools with
your finger on the switch or energizing power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left

Drilling
1. Secure the material to be drilled in a vise or with clamps to keep it from turning as the drill bit
rotates.
2. Install the correct bit.
3. Verify that the direction-of-rotation selector is at the correct setting (forward).
4. Hold the hammer drill firmly and place the bit at the point to be drilled.
5. Press the trigger switch to start the hammer drill.
6. Move the drill bit into the workpiece, applying only enough pressure to keep the bit cutting. Do not
force the hammer drill or apply side pressure to elongate a hole. Allow the tool to do the work.
7. When drilling hard, smooth surfaces, use a centre punch to mark the desired location of the hole.
This will prevent the drill bit from slipping off-centre as the hole is started.
8. If the bit jams in the workpiece or if the drill stalls , stop the tool immediately. Reverse the direction of
rotation and gently squeeze the trigger switch to remove the bit from the workpiece. Investigate and
correct the cause of jamming before you resume work.
Drilling in wood
For maximum performance, use high-speed steel or brad-point bits for wood drilling.
1. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
2. Increase the speed as the drill bit enters the material.
3. When drilling holes all the way through the workpiece, place a block of wood behind the workpiece to
prevent ragged or splintered edges on the back side of the hole.
Drilling in metal
For maximum performance, use high-speed steel bits for metal or steel drilling.
1. When drilling metals, use light oil on the drill bit to keep it from overheating. The oil will prolong the
life of the bit and increase the drilling action.
2. Begin drilling at a very low speed to prevent the bit from slipping off the starting point.
3. Maintain a speed and pressure that allows cutting without overheating the bit. Applying too much
pressure will:
Overheat the hammer drill
Wear the bearings
Bend or burn the bits
Produce off-centre or irregularly shaped holes.
Drilling in masonry
For maximum performance, use carbide-tipped masonry bits when drilling holes in brick, tile, concrete,
etc.
1. Maintain a speed and pressure that allows cutting without overheating the bit or drill. Applying too
much pressure will:
Overheat the hammer drill
Wear the bearings
Bend or burn bits
Produce off-centre or irregular shaped holes.
2. Apply light pressure and medium speed for best results in brick.
3. Apply additional pressure for hard materials such as concrete.
4. When drilling holes in tile, practice on a scrap piece to determine the best speed and pressure. Begin
drilling at a very low speed to prevent the bit from slipping off the starting point.
