Preparations:
- Make a hole (with a diameter that fits the tap
used).
- Set the gear switch (4) to Gear "1" .
- Move the sliding switch (3) to " Thread
tapping "
- Adjust setting wheel (12) (see fig. below):
The appropriate setting depends on many factors,
in principle the following applies:
a) Blind holes and small through holes:
For blind holes, do not select too much torque so
that the tap does not snap when it reaches the
bottom of the hole. The Pulse position corre-
sponds to the smallest torque and the smallest
speed. Both values increase up to position 4.
b) Through holes:
Select a larger torque. From position 4 the speed
remains the same and only the torque increases.
For "Maximum torque" select position .
- Open the chuck.
- Insert tap .
- Insert taps of sizes M8 - M12, to the stop in the
chuck so that the square is held by the holder
inside the chuck.
- Smaller taps are held sufficiently tight by the
clamping jaws of the chuck.
- Close chuck and clamp tight .
- Lubricate hole and tap with appropriate cutting
oil .
Tappingthread
- Place tap on the hole.
- Move machine in axial direction.
- Depress the trigger switch (14) and at a low speed
and with moderate pressure, let the tap cut into the
hole. The speed can be increased during the
thread tapping.
- When the desired thread depth is reached, pull
the machine evenly from the hole while keep the
trigger switch (14) depressed. The machine
automatically changes its direction of rotation.
Note: If the sliding switch (3) is in the "Thread
tapping" position, right and left pulse functions
are not available.
Note: If the sliding switch (3) is in the position
"Thread tapping" position and there is no
pressure on the tap, the machine runs in left mode!
If pressure is placed on the tap, the machine
automatically changes to right mode.
7.10 Chuck with quick-change system Quick
Fig. I
To remove: Push the interlock ring forward (a),
advance and pull off the chuck (b).
To fit: push the interlock ring forward and move the
chuck as far as the limit stop on the drill spindle.
7.11 Fitting the belt hook (equipment-
specific) / bit depot (equipment-specific)
Fig. J
Fit the belt hook (7) as shown.
Fit the bit depot (6) as shown.
8.1 The machine's multifunctional
monitoring system
If the machine switches off automatically, the
machine electronics have activated automatic
protection mode. A warning signal sounds
(continuous beeping). The beeping stops after a
maximum of 30 seconds or when the trigger switch
(14) is released.
In spite of this protective function, overloading
is still possible with certain applications and
can result in damage to the machine.
Causes and remedies:
1. Battery pack almost empty Fig. A, B (The
electronics protect the battery pack against
damage through total discharge).
If one LED (10) is flashing, the battery pack is
almost flat. If necessary, press the button (9) and
check the LEDs (10) to see the charge level. If
the battery pack is almost flat, it must be
recharged.
2. Long continuous overloading of the machine will
activate the temperature cut-out .
Leave the machine or battery pack to cool.
Note: if the battery pack feels very warm, the
pack will cool more quickly in an "AIR COOLED"
charger.
Note: the machine will cool more quickly if you
operate it at idling speed.
3. Metabo safety shutdown : the machine has
SHUT DOWN by itself. If the speed suddenly
drops (for example, if the machine suddenly
seizes or kickback occurs), the machine
switches off. Switch off the machine at the
trigger switch (14). Switch it on again and
continue to work as normal. Try to prevent the
machine from seizing.
