3. Personal safety  
General safety rules  
a. 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.  
WARNING. Read all instructions. Failure to follow all  
instructions listed below may result in electric shock, fire  
and/or serious injury. The term “power tool” in all of the  
warnings listed below refers to your mains operated (corded)  
power tool or battery operated (cordless) power tool.  
Save these instructions  
1. Work area  
b. Use safety equipment. Always wear eye protection.  
Safety equipment such as dust mask, non-skid  
safety shoes, hard hat, or hearing protection used for  
appropriate conditions will reduce personal injuries.  
a. Keep work area clean and well lit.  
Cluttered and dark areas invite accidents.  
b. 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.  
c. Avoid accidental starting. Ensure the switch is in the  
off position before plugging in. Carrying power tools with  
your finger on the switch or plugging in power tools that  
have the switch on invites accidents.  
c. Keep children and bystanders away while operating a  
power tool. Distractions can cause you to lose control.  
d. Remove any adjusting key or wrench before turning  
the power tool on. A wrench or a key left attached to a  
rotating part of the power tool may result in personal injury.  
2. Electrical safety  
a. 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.  
e. Do not overreach. Keep proper footing and balance at  
all times. This enables better control of the power tool in  
unexpected situations.  
f. 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.  
b. 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.  
g. If devices are provided for the connection of dust  
extraction and collection facilities, ensure these are  
connected and properly used. Use of these devices  
can reduce dust related hazards.  
c. Do not expose power tools to rain or wet conditions.  
Water entering a power tool will increase the risk of  
electric shock.  
d. 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.  
4. Power tool use and care  
a. Do not force the power tool. Use the correct power tool  
for your application. The correct power tool will do the job  
better and safer at the rate for which it was designed.  
e. When operating a power tool outdoors, use an  
extension cord suitable for outdoor use. Use of a cord  
suitable for outdoor use reduces the risk of electric shock.  
b. 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.

If possible, always use clamps or a vice to hold your work.  
Always switch off before you put the drill down.  
Ensure that the lighting is adequate.  
c. Disconnect the plug from the power source before  
making any adjustments, changing accessories, or  
storing power tools. Such preventive safety measures  
reduce the risk of starting the power tool accidentally.  
Do not put pressure on the drill, such that it slows the  
motor down. Allow the drill bit to cut without pressure. You  
will get better results and you will be taking better care of  
your tool.  
d. 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.  
Keep the area free of tripping hazards.  
e. Maintain power tools. Check for misalignment or  
binding of moving parts, breakage of parts and  
any other condition that may affect the power tools  
operation. If damaged, have the power tool repaired  
before use. Many accidents are caused by poorly  
maintained power tools.  
Do not let anyone under 18 years operate this tool.  
Only use accessory bits in good condition.  
Before drilling, check that there is sufficient clearance for  
the drill bit under the work piece.  
Do not touch the bit after operation. It will be very hot.  
Keep your hands away from under the work piece.  
f. Keep cutting tools sharp and clean. Properly maintained  
cutting tools with sharp cutting edges are less likely to bind  
and are easier to control.  
Never use your hands to remove sawdust, chips or waste  
close by the bit.  
g. Use the power tool, accessories and tool bits etc.,  
in accordance with these instructions and in the  
manner intended for the particular type of power  
tool, 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.  
Rags, cloths, cord, string and the like should never be left  
around the work area.  
Support the work properly.  
If you are interrupted when operating the drill, complete  
the process and switch off before looking up.  
Periodically check that all nuts, bolts and other fixings are  
properly tightened.  
5. Service  
a. 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.  
When using the drill, use safety equipment including  
safety glasses or shield, ear defenders, and protective  
clothing including safety gloves. Wear a dust mask if the  
drilling operation creates dust.  
Additional safety rules for drills  
WARNING. Before connecting a tool to a power source  
(mains socket power point receptacle, outlet, etc.) be sure  
that the voltage supply is the same as that specified on the  
nameplate of the tool. A power source with a voltage greater  
than that specified for the tool can result in serious injury to  
the user, as well as damage to the tool.  
Wear ear protectors with hammer drills.  
Exposure to noise can cause hearing loss.  
Use auxiliary handles supplied with the tool.  
Loss of control can cause personal injury.  
Fully unwind cable drum extensions to avoid potential  
overheating.  
If in doubt, do not plug in the tool. Using a power source  
with a voltage less than the nameplate rating is harmful to  
the motor.  
When an extension cable is required, you must ensure  
that it has the right ampere rating for your power tool and  
is in safe electrical condition.

Selecting the required function  
Hints for use  
It is possible to use the rotary  
hammer drill in four different  
modes of operation:  
Note. When drilling into masonry, the drilling rate is fast  
and burnout of the tip will occur if the drill bit is not  
constantly cleared.  
P
Q
R
S
1. Rotation only  
Use only correctly sharpened  
drill bits, which are suitable for  
the material being drilled.  
T
Non hammer action, non pneumatic  
For drilling into metal and wood  
products, can be used with the  
13mm keyed chuck (Fig. P).  
To drill hard materials, firm  
pressure is required on  
the power tool. However,  
excessive pressure does not  
improve performance and  
places unnecessary pressure  
on the tool and its bit.  
2. Rotary hammer action  
Pneumatic  
For drilling into brick  
and masonry products (Fig. Q).  
CAN NOT be used with the  
13mm keyed chuck.  
When driving screws, always use a pilot hole and set the  
speed dial to low. Press firmly on the screw head and pull  
the trigger gradually increasing the speed. It is always  
wiser to test the screw driving on a scrap piece of the  
same material you are using.  
Use SDS drill bits only.  
3. Chisel rotation mode  
Allows the operator to rotate a flat  
chisel to the most suitable angle  
for the task (Fig. R).  
CAN NOT be used with  
the 13mm keyed chuck.  
Larger diameter holes in hard wood, steel and concrete  
have to be drilled at slower speeds. However, the motor  
must not be struggling with the operation. If the motor is  
struggling DO NOT continue working, pull the drill clear of  
the work piece and run it on fast speed for a minute or so  
allowing the motor time to cool down before you attempt  
a little more of the work. If the job is too hard for the drill,  
do not continue, otherwise permanent damage to the  
motor will occur.  
4. Non rotating, pneumatic  
hammer action  
For light demolition work or  
chiselling such as lifting tiles (Fig. S).  
CAN NOT used with the 13mm  
keyed chuck.  
Wire brushing or sanding should be carried out on the  
highest speed.  
Concrete drilling should be carried out on the highest  
speed. DO NOT overload motor when drilling concrete.  
DO NOT use too much pressure as the hammer action  
relies on the drill bit being able to move back and forward  
in the hole being drilled. Always clear the flutes of the drill  
bit by removing it from the hole regularly.  
1. To select the required mode of  
operation, press the selector  
button (7) and set selector knob  
(6) to the appropriate position.  
2. Release the button (7).

Fitting the keyed chuck  
Maintenance  
The keyed chuck (14) supplied as an accessory can be  
fitted to the SDS chuck with the use of the SDS chuck  
adaptor (12).  
WARNING. Always ensure that the tool is switched off and  
the plug is removed from the power socket before making  
any adjustments or maintenance procedures.  
1. The keyed chuck allows bits with a straight shank to be  
used with the tool.

secure place. In this way you will always have all the  
information and parts ready to hand.  
2. Grip and pull back the locking sleeve (11) and insert the  
SDS chuck adaptor (12) (Fig. U).  
Keep your machine and its cord clean. The outside of the  
machine can be cleaned using a damp soft cloth with a mild  
detergent if required.  
3. It may be necessary to turn the SDS chuck adaptor in  
order for it to locate properly (Fig. V).  
Some maintenance products and solvents may damage the  
plastic parts; these include products containing benzene, 25  
trichloroethylene, chloride and ammonia.  
U
V
CAUTION. Water must never come into contact with the tool.  
Excessive sparking generally indicates the presence of dirt  
in the motor or abnormal wear on the carbon brushes.  
Take special care to keep the ventilation inlets/outlets free  
from obstruction; cleaning with a soft brush followed by  
a compressed air jet will usually be sufficient to ensure  
acceptable internal cleanliness.  
4. Release the locking sleeve (11) to lock the adaptor in  
place (Fig. W).  
Wear eye protection when carrying out cleaning.  
5. Screw the keyed chuck (14) onto the threaded end of the

Regularly check that all the fixing screws are tight. They  
may vibrate loose over time.  
Regularly check to see if any dust or foreign matter has  
entered the grills near the motor and around the trigger  
switch. Use a soft brush to remove any accumulated dust.  
Wear safety glasses to protect your eyes whilst cleaning.  
Re-lubricate all moving parts at regular intervals.
