Maintenance And Cleaning - Metabo SBE 18 LTX Manual Original

Change speed only when the machine is in the
process of running down
(briefly switch On/Off).
1st gear (low speed, high torque) e.g. for
screwdriving, drilling
2nd gear (high speed) e.g. for drilling, impact
drilling
7.5 On/Off switch, modifying the speed
Switching on, speed: press the trigger switch (7).
Press in the trigger switch to increase the rotational
speed.
Switching off: release the trigger switch (7).
7.6 Tool change with the keyless chuck (2)
See illustration A on page 2.
Opening the chuck:
Hold the retaining ring and turn the sleeve with your
other hand in direction of the arrow -1-.
The grating sound which may be heard after
opening the chuck is functional and is stopped by
turning the sleeve in the opposite direction.
If the chuck is extremely tight: disconnect the mains
plug. Hold the chuck using an open-end spanner at
the flats on its head, and turn the sleeve vigorously
in the direction of the arrow -1.
Clamping the tool:
- Insert the tool -2- as far as possible.
- Grip the retaining ring firmly and, with the other
hand, turn the sleeve in the direction of the arrow -
3- until the mechanical resistance which can be
felt is overcome.
- Caution! The tool is not yet clamped! Keep
turning the sleeve (it must "click" when
turning), until it cannot be turned any further -
only now is the tool securely clamped.
With a soft tool shank, retightening may be required
after a short drilling period.
7.7 Unscrewing the chuck (when screwing
without the chuck or when using
attachments)
See illustration B on page 3.
Loosen and remove as shown by tapping gently
with a rubber hammer
Note: if a bit clamping bush (order no. 6.31281) is
attached, the screwdriver bit inserted in the
hexagon socket of the spindle is held in place.
8. Troubleshooting
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
(7) 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 flat: (the electronics
prevent the battery pack form discharging totally
and avoid damage).
If one LED is flashing, the battery pack (10) 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 slew rate of the
current is too high (for example, if the machine
suddenly seizes or kickback occurs), the
machine switches off. Switch off the machine at
the trigger switch (7). Switch it on again and
continue to work as normal. Try to prevent the
machine from seizing.

9. Maintenance and Cleaning

The vent slots of the machine should be cleaned
periodically.
Remove the battery pack periodically and wipe the
contact area of the battery pack and machine with a
dry cloth and remove drilling dust.
Keyless chuck cleaning:
After prolonged use, hold the chuck vertically with
the opening facing downwards and fully open and
close it several times. The dust collected falls from
the opening. Regular use of cleaning spray on the
jaws and jaw openings is recommended.

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.
