▶
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.
▶
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.
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.
▶
Do not use a battery pack or tool that is damaged or modified. Damaged or modified batteries may
exhibit unpredictable behaviour resulting in fire, explosion or risk of injury.
▶
Do not expose a battery pack or tool to fire or excessive temperature. Exposure to fire or temperature
above 130° C (265 °F) may cause explosion.
▶
Follow all charging instructions and do not charge the battery pack or tool outside the temperature
range specified in the instructions. Charging improperly or at temperatures outside the specified range
may damage the battery and increase the risk of fire.
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.
▶
Never service damaged battery packs. Service of battery packs should only be performed by the
manufacturer or authorized service providers.
2.2 Additional safety instructions
▶
Observe all safety instructions in this documentation and in the documentation of the Hilti rotary hammer
drill.
▶
Use respiratory protection to keep residual dust away from the face and airways when drilling and when
servicing the tool or accessories.
▶
Always use the side handle on the Hilti rotary hammer drill, even when the dust removal module is fitted.
▶
Wear protective gloves.
▶
Take breaks between working and do physical exercises to improve the blood circulation in your fingers.
Exposure to vibration during long periods of work can lead to disorders of the blood vessels and nervous
system in the fingers, hands and wrists.
▶
Use the TE DRS-4/6 dust removal module for dust extraction. Dust from materials such as lead-based
paints, certain types of wood and concrete/masonry/stone containing quartz, minerals or metal can be
harmful to health.
▶
Make sure that the workplace is well ventilated and, where necessary, wear a dust mask appropriate for
the type of dust generated. Contact with or inhalation of the dust may cause allergic reactions and/or
respiratory or other diseases among operators or bystanders. Certain kinds of dust, such as oak and
beech dust, are classified as carcinogenic, especially in conjunction with additives for treating wood
(chromate, wood preservative).
▶
Always use the extraction head that is appropriate for the application (drilling or chiseling). The standard
extraction head is suitable for drilling applications only.
▶
Risk of injury by falling tools and/or accessories. Before starting work, check that installed accessories
are secure.
