VERTO 50G291 Betriebsanleitung Seite 12

* In certain cases position of the switch related to rotation may be
different than specified. Please refer to graphic signs placed on the
switch or tool body.
Safe position of the direction selector switch (3) is in the middle, it
prevents accidental starting of the power tool.
• Drill cannot be started, when the switch is in this position.
• Use this position of the switch to change drills or bits.
• Before starting the tool make sure the position of the direction
selector switch (3) is correct.
Do not change direction of rotation when the drill spindle is
rotating.
CHANGE OF GEAR
Gear switch (8) (fig. H) allows to increase the range of rotational
speed.
Gear I: small speed range, big torque
Gear II: greater speed range, small torque.
Set the gear switch in position appropriate for the works to perform.
When the switch is blocked and cannot be moved, turn the spindle
slightly.
Never change the gear switch position when the drill is
operating. It may damage the power tool.
Long lasting drilling at low rotational speed of the spindle may
cause motor overheating. Provide regular breaks during
operation or let the tool operate at maximum speed with no
load for approximately 2–3 minutes.
OPERATION AND MAINTENANCE
MAINTENANCE AND STORAGE
• Cleaning the device after each use is recommended.
• Do not use water or any other liquid for cleaning.
• Clean the drill with a dry cloth or blow with compressed air at
low pressure.
• Do not use any cleaning agents or solvents, they may damage
plastic parts.
• Clean ventilation holes in the motor casing regularly to prevent
device overheating.
• In case of excessive commutator sparking, have the technical
condition of carbon brushes of the motor checked by a qualified
person.
• Store the drill in a dry place, beyond reach of children.
QUICK RELEASE CHUCK REPLACEMENT
Quick-release chuck is screwed onto spindle of the drill and
additionally secured with a screw.
• Set the direction selector switch (3) in the middle position.
• Open jaws of quick release chuck (1) and unscrew the fixing
screw (left-hand thread) (fig. F).
• Install hexagonal key in the quick release chuck and tap the other
end of the key.
• Unscrew the quick release chuck.
• Installation of the quick release chuck is similar to deinstallation,
only the sequence of actions is reversed.
All defects should be repaired by service workshop authorized by
the manufacturer.

Information regarding noise and vibration
The following levels of emitted noise, such as emitted acoustic
pressure LpA and acoustic power level LwA and measurement
uncertainty K have been given in the instruction manual as defined
in the EN 60745
standard.
The following vibration value (acceleration value) ah and
measurement uncertainty K have been determined as defined in the
EN 60745-2-1 standard. The vibration level provided in this
instruction manual have been
determined according to the measurement procedure as defined in
the EN 60745 standard and can be used for comparison of power
tools. This can be used for preliminary assessment of exposure to
vibrations.
The provided vibration level is representative for main applications
of the power tool. If the power tool is used for other applications or
