▶ Wear protective gloves when changing accessory tools as accessory tools get hot during use and
cutting edges of saw blades are sharp.
▶ Switch the product on only after bringing it into the working position.
▶ Never use the power tool without the hand guard fitted.
▶ Engage the transport lock before storing or transporting the tool.
▶ Avoid unintentional starting. Don't carry the tool with your finger on the control switch. Remove the
battery from the power tool during work breaks, before carrying out maintenance, before changing
accessory tools and before transporting the power tool.
▶ Observe the national health and safety requirements.
▶ Dust from materials, such as paint containing lead, some wood species, concrete / masonry / stone
containing silica, and minerals as well as metal, may be harmful. Contact with or inhalation of the dust
may cause allergic reactions and/or respiratory or other diseases to the operator or bystanders. Certain
kinds of dust are classified as carcinogenic such as oak and beech dust, especially in conjunction with
additives for wood conditioning (chromate, wood preservative). Material containing asbestos may be
handled only by specialists. Use a dust removal system whenever possible. To achieve a high level
of dust collection, use a suitable vacuum cleaner. When indicated, wear a respirator appropriate
for the type of dust generated. Ensure that the workplace is well ventilated. Follow national
requirements for the materials you want to work with.
Electrical safety
▶ Before beginning work, check the working area (e.g. using a metal detector) to ensure that no
concealed electric cables or gas and water pipes are present. External metal parts of the power tool
may become live, for example, when an electric cable is damaged accidentally. This presents a serious
risk of electric shock.
Special safety instructions for reciprocating saws
▶ Always guide the power tool away from your body when working with it.
▶ Never position your hands ahead of or on the saw blade.
▶ 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.
▶ Apply moderate pressure and select a suitable stroke rate when using the pipe-cutting adapter
(accessory), especially when cutting large-diameter pipes. This will help to prevent the power tool
overheating.
▶ Warning! When cutting through pipes, e.g. when carrying out demolition or installation work,
check to ensure that the pipes no longer contain liquids and empty them 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 dampness. Liquids
running out of pipes may cause a short circuit in the power tool.
▶ Do not attempt to cut material thicker than the specified max. thickness for which the saw is
designed and do not use unsuitable saw blades (reciprocating saw blades of the wrong size or not
equipped with a 1/2" connection end).
Careful handling and use of batteries
▶ Observe the special guidelines applicable to the transport, storage and use of lithium-ion batteries.
▶ Do not expose batteries to high temperatures and keep them away from fire. There is a risk of
explosion.
▶ Avoid ingress of moisture. Ingress of moisture may cause a short circuit, resulting in burning injuries or
fire.
▶ Do not disassemble, crush or incinerate batteries and do not subject them to temperatures over
80°C (176°F). This presents a risk of fire, explosion or injury through contact with caustic substances.
▶ Never continue to use or attempt to charge damaged batteries, e.g. batteries with cracks, broken
parts, bent or pushed-in / pulled-out contacts).
▶ Do not use the battery as a power source for other unspecified power tools or appliances.
▶ If the battery is too hot to touch it may be defective. In this case, place the power tool in a non-
flammable location, well away from flammable materials, where it can be kept under observation
and allowed to cool down. Contact Hilti Service after the battery has cooled down.
