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.
NOTE The temperature „130 °C" can be replaced by the temperature „265 °F".
g) 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.
6) Service
a) 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.
b) Never service damaged battery packs. Service of battery packs should only be performed by the
manufacturer or authorized service providers.
3.2.2 DRILL SAFETY WARNINGS
− Wear ear protectors when impact drilling. Exposure to noise can cause hearing loss.
− 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.
3.2.3 SAFETY INSTRUCTIONS WHEN USING LONG DRILL BITS
a) Never operate at higher speed than the maximum speed rating of the drill bit. At higher speeds, the
bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in personal injury.
b) Always start drilling at low speed and with the bit tip in contact with the workpiece. At higher
speeds, the bit is likely to bend if allowed to rotate freely without contacting the workpiece, resulting in
personal injury.
c) Apply pressure only in direct line with the bit and do not apply excessive pressure. Bits can bend
causing breakage or loss of control, resulting in personal injury.
3.2.4 SAFETY INSTRUCTIONS FOR BATTERIES AND CHARGER
Batteries
Never attempt to open for any reason.
Do not store in locations where the temperature may exceed 40° C (104° F).
Charge only at ambient temperatures between 4° C and 40° C(39.2° F and 104° F).
Charge only using the charger provided with the tool.
Store your batteries in a cool dry place (5° C-20° C/41° F-68° F). Never store batteries in discharged
state.
It is better for Li-ion batteries to discharge and reload them regularly (at least 4 times a year). The
ideal charge for long-term storage of your Li-ion battery is 40% of capacity.
When disposing of batteries, follow the instructions given in the section "Protecting the
environment".
Do not cause short circuits. If connection is made between the positive (+) and negative (-) terminal
directly or via accidental contact with metallic objects, the battery is short circuited and an intense
current will flow causing heat generation which may lead to casing rupture or fire.
Do not heat. If batteries are heated to above 100° C (212° F), sealing and insulating separators and
other polymer components may be damaged resulting in electrolyte leakage and/or internal short
