5 GENERAL POWER TOOL SAFETY WARNINGS
WARNING：Read all safety warnings and all instructions. Failure to follow the warnings and
instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference!
The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-
operated (cordless) power tool.
5.1 Work area safety
a) Keep work area clean and well lit. Cluttered or 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) Keep children and bystanders away while operating a power tool. Distractions can cause you to
lose control.
5.2 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 the risk of electric shock.
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.
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.
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.
f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD)
protected supply. Use of an RCD reduces the risk of electric shock.
5.3 Personal safety
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.
b) Use personal protective equipment. Always wear eye protection. Protective equipment such as a
dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions
will reduce personal injuries.
c) 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 energising power tools that have the switch on invites accidents.
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.

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.
g) If devices are provided for the connection of dust extraction and collection facilities, ensure
these are connected and properly used. Use of dust collection can reduce dust-related hazards.
5.4 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.
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.
c) 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.
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.
e) 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.
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.
g) Use the power tool, accessories and 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.
5.5 Battery Tool use and care
a) Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type
of battery pack may create a risk of fire when used with another battery pack.
b) Use power tools only with specifically designated battery packs. Use of any other battery packs may
create a risk of injury and fire.
c) When battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys,
nails, screws or other small metal objects, that can make a connection from one terminal to another.
Shorting the battery terminals together may cause burns or a fire.
d) Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact
accidentally occurs, flush with water. If liquid contacts eyes, additionally seek medical help. Liquid
ejected from the battery may cause irritation or burns.
5.6 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.

lowest and “ ” denote highest.
Torque is set by means of a torque setting according to different screw types and different materials. If
the screw is long and the material is hard, you can adjust to a higher torque setting as follows:
1 - 5
For driving small screws
6 - 10
For driving screws into soft material
11 - 16
For driving screws into soft and hard material
17 - 21
For driving screws into hard wood
For heavy drilling
11.8 Speed selector (Fig. 10)
Low speed Position
High speed Position
Fig. 10
NOTE : Mark “1”is the Low speed position, mark “2”is the High speed position. It is moulded into the
button of two speed selector (3).
The drill has a two-speed gear train designed for drilling at 1 (LOW) or 2 (HIGH) speed.
A gear selector is located on top of the drill to select either low or high speed. When you push the
button (3) forward and select low speed range, the speed will decrease but will provide more power and
torque.
When using the cordless drill in the high speed range, the speed will increase but will provide less power
and torque.
Use low speed for high power and torque application and high speed for fast drilling applications.
IMPORTANT: To avoid damage NEVER adjust this two speed selector（3）whilst the
drill is running. Always let it come to a complete stop first.

11.9 Drilling
Before drilling, the torque setting should be set on drill position “ ”.
When drilling hard smooth surface, use a centre punch to mark the desired hole location. This will
prevent the drill bit from slipping off centre as the hole is started. Hold the tool firmly and place the tip
of the drill or bit into the work piece, applying only enough pressure to keep the bit cutting. Do not force
or apply side pressure to elongate a hole.
11.9.1 Wood Drilling
For maximum performance, use high speed steel drill bits for wood drilling, turn the torque setting on
the drill position“ ”. Begin drilling at a very low speed to prevent the bit from slipping off the starting
point. Increase the speed as the drill bit bites into the material. When drilling through holes, place a
block or wood behind the work piece to prevent ragged or edges on the back side of the hole.
11.9.2 Metal drilling
For maximum performance, use high speed steel bits for metal or steel drilling. Turn the torque setting
on the drill position“ ”. Begin drilling at a very low speed to prevent the bit from slipping off the
starting point. Maintain a speed and pressure which allows cutting without overheating the bit. Applying
too much pressure will overheat the drill; wear the bearings, bend or burn bits, produce off-centre or
irregular shaped holes.
When drilling large holes in metal, it is recommended that you drill with a small bit at first, then finish
with a large bit, also lubricate the bit with oil to improve drilling action and increase bit life.
