Basic Working Techniques - Husqvarna DM 220 Operator's Manual

Use and care
• This machine is ideal for drilling holes in concrete, bricks
and various stone materials. It can be used both as a
hand-held drill or fitted to a drill stand.
• The machine is intended for use in industrial applications
by experienced operators.
• Inspection and/or maintenance should be carried out with
the motor switched off and the plug disconnected.
• The machine has a very high torque. This demands good
concentration during work, as serious personal injuries
can occur if the drill bit suddenly jams.
• Do not use the power tool if the switch does not turn it on
and off. Any power tool that cannot be controlled with the
switch is dangerous and must be repaired.
• Remain at a distance from the drill bit when the motor is
running.
• Do not overload the machine. Overloading can damage
the machine.
• Keep tools sharp and clean in order to enable safer work.
• Keep all parts in good working order and ensure that all
fixtures are properly tightened.
• Always switch off the machine before you move it.
Dry drilling
CAUTION! Dust forms when drilling, which
!
can cause injuries if inhaled. Use an
approved breathing mask. Connected the
machine to a vacuum cleaner for effective
dust management when dry drilling.
Drilling in the ceiling
NOTICE! The air intake must not be covered.
Use a water collector to avoid water penetrating into the
machine.
Elgard™
NOTICE! Do not repeatedly overload the machine. This can
damage the machine.
If the motor is overloaded, the overload protection pulses the
motor. Reduce the load and the motor returns to its normal
speed.
The overload protection disconnects the power, if the
machine is subjected to heavy loads or if the drill bit jams.
Reset the machine by switching it off and then on again.
If the drill bit jams, the mechanical slip clutch protects the
gearbox before the overload protection disconnects the
power.

OPERATING
Handheld drilling
!
• Always use a drill bit with a max. diameter of 75 mm with
handheld drilling. The larger the drill bit the greater the
reaction if the drill jams.
• Lock the front pivoting handle firmly in place prior to
drilling.
• Never perform handheld drilling from a ladder. Handheld
drilling in these situations is full of risks, as the risk of
falling is very high if the drill bit jams.
Stand drilling
• Always use a drilling stand if drilling is to be performed
from a ladder or scaffold.
• Make sure that the stand is secured correctly.
• Make sure that the drilling machine is secured correctly in
the stand.

Basic working techniques

Level guiding system
The machine's Level guiding system works like an electronic
level and helps the user to drill in the required position. By
reading the LED indicator on the top of the machine and
adjust it accordingly, it makes drilling easier for the operator
and offers better precision.
WARNING! Do not perform handheld drilling
in first gear as the machine has a powerful
torque that can result in personal injuries
should the drill bit jam.
