2 Safety
2.1 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.
Work area safety
▶ Keep 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
▶ 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.
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.
2 English
Printed: 16.04.2018 | Doc-Nr: PUB / 5408786 / 000 / 03
▶ 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 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.
▶ 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.
▶ 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 these
are connected and properly used. Use of dust collection 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 safer 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 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 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.
Battery tool use and care
▶ 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.
▶ Use power tools only with specifically designated battery packs. Use of any other battery packs may
create a risk of injury and fire.
▶ 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.
▶ 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.
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.
2.2 Safety instructions for jig saw / reciprocating saw
▶ Hold power tool by insulated gripping surfaces, when performing an operation where the cutting
accessory may contact hidden wiring. Cutting accessory contacting a "live" wire may make exposed
metal parts of the power tool "live" and could give the operator an electric shock.
2.3 Additional safety instructions
▶ Use the product only if it is in perfect working order.
▶ Never tamper with or modify the product in any way.
▶ Do not use dull/blunt or damaged blades. These cause increased friction and present a high risk of the
saw blade binding or kicking back.
English 3
Printed: 16.04.2018 | Doc-Nr: PUB / 5408786 / 000 / 03
▶ Before beginning the work, check the working area for concealed electric cables or gas and water pipes.
External metal parts of the power tool may become live, presenting a risk of electric shock, if the blade
inadvertently cuts into a live electric cable.
▶ Secure the workpiece to a stable support. Never hold the piece being cut in your hands or across your
leg.
▶ Switch the product on only after bringing it into the working position.
▶ Always guide the power tool away from your body when working with it.
▶ Apply only moderate pressure and cut at an appropriate speed, especially when cutting large-diameter
pipes. This will help to prevent the power tool overheating.
▶ Before cutting through pipes, make sure that the pipes are empty, i.e. that they do not contain liquids.
Drain the pipes if necessary.
▶ When cutting through pipes, hold the power tool above the level of the pipe you are cutting through.
◁ The power tool incorporates no protective measures to prevent ingress of water or moisture. Liquids
running out of pipes may cause a short circuit in the power tool.
▶ Never cut into unknown materials and keep the line of cut above and below the workpiece free of
obstacles.
◁ If the saw blade strikes an object it may cause the power tool to kick back.
▶ Wear protective gloves also when changing the accessory tool. Touching the accessory tool presents a
risk of injury (cuts or burns).
▶ Always remove the battery when the power tool is not in use, before maintenance, before changing
accessory tools and before transport.
▶ Engage the transport lock before storing or transporting the power tool.
▶ Observe the manufacturer’s instructions regarding the handling and storage of saw blades.
2.4 Battery use and care
▶ Observe the special regulations and instructions applicable to the transport, storage and use of Li-ion
batteries.
▶ Do not expose batteries to high temperatures, direct sunlight or fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over 80 °C.
▶ Do not use or charge batteries that have suffered mechanical impact, have been dropped from a height
or show signs of damage. In this case, always contact your Hilti Service.
▶ If the battery is too hot to touch it may be defective. In this case, place the product in a non-flammable
location, well away from flammable materials, where it can be kept under observation and allowed to
cool down. In this case, always contact your Hilti Service.
