A wrench or a key
left attached to a rotating part of the power tool may result in personal injury.
This enables better control of
the power tool in unexpected situations.
Loose clothes, jewellery or long hair can be caught in moving parts.
Use of these devices can reduce dust-related hazards.
Power tool use and care
The correct
power tool will do the job better and more safely at the rate for which it was designed.
Any power tool that
cannot be controlled with the switch is dangerous and must be repaired.
Such
preventive safety measures reduce the risk of starting the power tool accidentally.
Power tools are
dangerous in the hands of untrained users.
Many accidents are caused by poorly maintained
power tools.
Properly maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
Use of the power
tool for operations different from those intended could result in a hazardous situation.
Service
This will ensure that the safety of the power tool is maintained.
SAFETY GUIDELINES
Work area safety
Cluttered or dark areas invite accidents.
Power tools create sparks, which may ignite the dust or fumes.
Distractions can cause
you to lose control.
Electrical safety
Unmodified plugs and matching
outlets will reduce the risk of electric shock.
There is an increased risk of electric shock if your body is earthed or grounded.
Water entering a power tool will increase
the risk of electric shock.
Damaged or
entangled cords increase the risk of electric shock.
Use of a cord suitable for outdoor use reduces the risk of electric shock.
Use of a GFCI reduces the risk of electric shock.
Personal safety
A moment of inattention while operating power tools may result in serious personal injury.
Protective equipment such
as dust mask, non-skid safety shoes, hard hat, or hearing protection, used for appropriate conditions,
will reduce personal injuries.
Carrying power tools
with your finger on the switch or energising power tools that have the switch on invites accidents.

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. Unplug the hammer drill from the power source.
3. Install the auxiliary handle and the correct bit.
4. Connect the hammer drill to the power source
5. Verify that the direction-of-rotation selector is at the correct setting (forward).
6. Hold the hammer drill firmly with one hand on the primary handle and the other hand on the
auxiliary handle
7. Place the bit at the point to be drilled.
8. Press the trigger switch to start the hammer drill.
9. 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.
10. 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.
11. 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.
12. 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.
Installing bits (fig 6)
1. Unplug the hammer drill from the power source.
2. Open the chuck jaws by turning the sleeve in
a counterclockwise direction until the opening
is slightly larger than the bit you intend to use,
and raise the front of the drill slightly to keep
the bit from falling out of the chuck jaws.
3. Insert the drill bit into the chuck.
4. Tighten the sleeve by hand.
5. Place the chuck key in one of the three chuck key holes and tighten in clockwise direction. Repeat
with the remaining two chuck key holes.
WARNING!
It is important to tighten the chuck with all three key holes to prevent slippage.
6. Remove the chuck key.
WARNING!
Insert the drill bit straight into the chuck jaws. Inserting the drill bit into the chuck jaws at an
angle and then tightening the chuck and using the drill could cause the drill bit to be thrown
from the hammer drill, resulting in possible serious personal injury or damage to the chuck.
Removing bits (fig 7)
WARNING!
Use protective gloves when removing
the bit from the tool, or allow the bit
to cool down first. The bit may be hot
after prolonged use.
1. Unplug the hammer drill from the power source.
2. Place the chuck key in one of the three chuck
key holes and loosen the chuck by turning in a
counterclockwise direction.
3. Remove the chuck key.

Before each use
1. Inspect the hammer drill, the trigger switch, the cord and the accessories for damage.
2. Check for damaged, missing, or worn parts.
3. Check for loose screws, misalignment or binding of moving parts, or any other condition that may
affect the operation.
4. If abnormal vibration or noise occurs, turn the tool off immediately and have the problem
corrected before further use. Unplug the tool from power source before cleaning or performing
any maintenance. Using compressed air may be the most effective cleaning method. Always wear
safety goggles when cleaning tools using compressed air.
WARNING!
Do not allow brake fluids, gasoline and petroleum-based products, penetrating oil, etc.
to come into contact with plastic parts. These substances contain chemicals that can
damage, weaken, or destroy plastic.
WARNING!
When servicing, use only identical replacement parts. The use of any other parts may
create a hazard or cause damage to the product.
WARNING!
If the supply cord of this power tool is damaged, it must be replaced by a specially
prepared cord available through the service organization.
WARNING!
Use only accessories that are recommended for this hammer drill by the manufacturer.
Accessories that may be suitable for one tool may become hazardous when used with
another tool.
WARNING!
Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools
with sharp cutting edges are less likely to bind, and are easier to control.
WARNING!
To ensure safety and reliability, all repairs should be performed by a qualified service
technician.
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.
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
For maximum performance, use carbide-tipped masonry bits when drilling holes in brick, tile, concrete, etc.
1. Maintain a speed and pressure which 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.
