Metabo B 32/3 Manual Original página 11

The locking button () must be released after
every machine-related standstill or after a
current interruption to prevent accidental restart of
the machine (risk of injury)!
7.2 Three-speed gearing
Do not actuate the thumb-wheel () unless the
motor has completely stopped.
Select the desired speed by turning the thumb-
wheel ().
If necessary, the switching procedure can be
supported by turning the drill spindle slightly.
7.3 Overload protection
The machine is equipped with a mechanical
overload protection device to protect the operator,
motor and tool.
If the tool jams suddenly, the drill spindle is
decoupled from the motor by means of a slip clutch.
The slip clutch is designed to absorb impact and
excessive load. As it is only an aid, and does not
provide total protection, you should always drill
carefully. To retain its operability, it should slip
through for a maximum of 2 seconds. In case of
excessive wear, it must be replaced by an
authorised specialist workshop.
7.4 Inserting and removing tool
Inserting and removing tool:
Perfect seating of the tool in the drill spindle ()
can only be guaranteed if the female taper of
the drill spindle and the taper shank of the tool are
free of dirt and grease.
Caution! Never use excessive force to press
tools into the female taper of the drill spindle!
Always use sharp tools in perfect condition.
Switch off the machine. Pull the mains plug out
of the socket.
Tools with taper shank MK3 can be inserted directly
in the toolholder ().
For all other tools, refer to the chapter 10.
Accessories and the illustration of page 4.
Removing tool:
Insert the removal tool - with the sloping edge
against the drill - in the slot () on the machine neck.
If it cannot be inserted through the drill spindle, you
should turn it slightly by hand. Drive out the tool by
knocking lightly on the removal tool with a hammer.
8. Cleaning
Regularly clean the power tool's air vents.
9. Troubleshooting
Switching on the machine briefly reduces the
voltage. Unfavourable mains power conditions may
have a detrimental effect on other machines. Power
impedances less than 0.35 ohm should not cause
malfunctions.
10. Accessories
Use only genuine Metabo accessories.
Use only accessories that fulfil the requirements
and specifications listed in these operating
instructions.
Fit accessories securely. If the machine is operated
in a holder: secure the machine well. Loss of control
can cause personal injury.
