Overload Clutch - DeWalt D25413 Original Instructions Manual

EngLIsh
• Apply only a gentle pressure to the tool (approx.
5 kg). Excessive force does not speed up drilling but
decreases tool performance and may shorten tool life.
• Do not drill or drive too deep to prevent damage to the
dust cover.
• Always hold the tool firmly with both hands and
ensure a secure stance (Fig. G). Always operate the
tool with the side handle properly mounted.
Proper Hand Position (Fig. G)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the side handle
with the other hand on the main handle

Overload Clutch

If the drill bit becomes jammed or caught, the drive to the drill
spindle is interrupted by the overload clutch. Because of the
forces that occur as a result, always hold the machine securely
with both hands and take a firm stance.

speed switch 1 . Drill until the core penetrates into the
concrete approx. 1 cm.
6. Stop drilling and remove the centredrill. Place the core bit
back into the hole and continue drilling.
7. When drilling through a structure thicker than the depth of
the core bit, break away the round cylinder of concrete or
core inside the bit at regular intervals. To avoid unwanted
breaking away of concrete around the hole, first drill a hole
the diameter of the center drill completely through the
structure. Then drill the cored hole halfway from each side.
8. Always switch off the tool when work is finished and
before unplugging.
