Hilti SF 10W­A22 Original Operating Instructions page 21

▶ 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 Drill safety warnings
▶ Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
▶ 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 Drill/driver safety warnings
▶ Hold power tool by insulated gripping surfaces, when performing an operation where the fastener
may contact hidden wiring. Fasteners contacting a "live" wire may make exposed metal parts of the
power tool "live" and could give the operator an electric shock.
2.4 Additional safety instructions
Personal safety
▶ Tampering with or modification of the power tool is not permitted.
▶ Always hold the tool securely with both hands on the gripping section. Always grip the side handle
at its outermost end. Keep the grips dry, clean and free from oil and grease. When drilling and
screwdriving, the grip of the power tool may be deflected laterally (the power tool tends to pivot about its
own axis).
▶ Avoid touching rotating parts. Switch the power tool on only after bringing it into position at the
workpiece. Touching rotating parts, especially rotating accessory tools, may lead to injury.
▶ Activate the safety lock (forward/reverse selector switch in the middle position) when changing
accessory tools or batteries and before storage or transportation of the power tool.
▶ Wear protective gloves. The drill/driver may get hot during use. There is a risk of injury (cutting or
burning) if the accessory tool is touched while changing it.
▶ The user and any other persons in the vicinity must wear suitable eye protection, a hard hat, ear
protection, protective gloves and breathing protection while the power tool is in use.
▶ Improve the blood circulation in your fingers by relaxing your hands and exercising your fingers
during breaks between working.
▶ 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.
▶ Before beginning the work, check the hazard classification of the dust that will be produced. Use
an industrial vacuum cleaner with an officially approved protection classification in compliance
with locally applicable dust protection regulations.
▶ Working on the material may cause it to splinter. Wear eye protection. Flying fragments present a risk
of injury to the body and eyes.
▶ The power tool is not intended for use by debilitated persons who have received no special training.
Keep the power tool out of reach of children.
▶ Observe the national health and safety requirements.
