Husqvarna DM 540i Operator's Manual page 10

• Do not use a battery pack or tool that is damaged or
modified. Damaged or modified batteries may exhibit
unpredictable behavior 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.
Drill safety warnings
Safety instructions for operation
• Use the auxiliary handle(s). Loss of control can
cause personal injury.
• Hold the 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.
• Do not drill handheld from a ladder or a scaffold.
Safety instructions when using long drill bits
• 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.
• 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.
• 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.
Diamond drill safety warnings
• When performing drilling that requires the use of
water, route the water away from the operator's work
area or use a liquid collection device. Such
precautionary measures keep the operator's work
area dry and reduce the risk of electrical shock.
• Operate power tool by insulated grasping surfaces,
when performing an operation where the cutting
10
accessory may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
• Wear hearing protection when diamond drilling.
Exposure to noise can cause hearing loss.
• When the bit is jammed, stop applying downward
pressure and turn off the tool. Investigate and take
corrective actions to eliminate the cause of the bit
jamming.
• When restarting a diamond drill in the workpiece,
check that the bit rotates freely before starting. If the
bit is jammed, it may not start, may overload the tool,
or may cause the diamond drill to release from the
workpiece.
• When securing the drill stand with anchors and
fasteners to the workpiece, ensure that the
anchoring used is capable of holding and restraining
the machine during use. If the workpiece is weak or
porous, the anchor may pull out causing the drill
stand to release from the workpiece.
• When securing the drill stand with a vacuum pad to
the workpiece, install the pad on a smooth, clean,
non-porous surface. Do not secure to laminated
surfaces such as tiles and composite coating. If the
workpiece is not smooth, flat or well affixed, the pad
may pull away from the workpiece.
• Ensure there is sufficient vacuum before and during
drilling. If the vacuum is insufficient, the pad may
release from the workpiece.
• Never perform drilling with the machine secured by
the vacuum pad only, except when drilling
downwards.If the vacuum is lost, the pad will release
from the workpiece.
• When the drilling through walls or ceilings, ensure to
protect persons and the work area on the other side.
The bit may extend through the hole or the core may
fall out on the other side.
• When drilling overhead, always use the liquid
collection device specified in the instructions. Do not
allow water to flow into the tool. Water entering the
power tool will increase the risk of electric shock.
