⚠ General Power Tool Safety Warnings
Lists general safety warnings for power tools.
Some warnings do not apply to cordless riveters.
Please read and understand everything before using the cordless riveter.
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 ammable
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.
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. Unmodied plugs and matching outlets will
reduce 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.
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 inuence 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 dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.

⚠ General Power Tool Safety Warnings
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 nger 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.
h) Do not let familiarity gained from frequent use of tools allow you to become complacent and
ignore tool safety principles. A careless action can cause severe injury within a fraction of a
second.
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 o󰀨. 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 packfrom 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 a󰀨ect 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 di󰀨erent from those intended could result in a hazardous situation.
h) Keep handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles
and grasping surfaces do not allow for safe handling and control of the tool in unexpected
situations.
5. Battery tool use and care
a) Recharge only with the charger specied by the manufacturer. A charger that is suitable for one
type of battery pack may create a risk of re when used with another battery pack.
b) Use power tools only with specically designated battery packs. Use of any other battery packs
may create a risk of injury and re.
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 re.
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.
e) Do not use a battery pack or tool that is damaged or modied. Damaged or modied batteries
may exhibit unpredictable behaviour resulting in re, explosion or risk of injury.
f) Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or
temperature above 130 °C may cause explosion.
g) Follow all charging instructions and do not charge the battery pack or tool outside the
temperature range specied in the instructions. Charging improperly or at temperatures outside
the specied range may damage the battery and increase the risk of re.
6. Service
a) Have your power tool serviced by a qualied repair person using only identical replacement
parts. This will ensure that the safety of the power tool is maintained.
b) Never service damaged battery packs. Service of battery packs should only be performed by
the manufacturer or authorized service providers.
