Maintenance And Cleaning; Troubleshooting; Environmental Protection - Metabo KHE 2660 Quick Operating Instructions Manual

Inserting tools:
- Turn tool and insert until it engages. The tool is
automatically locked.
Remove the tool:
See page 2, fig. A.
- Pull tool lock (2) backwards in direction indicated
by arrow (a) and remove tool (b).
6.8 Tool change keyless chuck (depends on
equipment)
Use the keyless chuck when drilling without impact
into metal, wood etc. and for driving in screws.
Clamp tool (see p.2, fig. B):
Turn sleeve (5) in direction "OPEN, RELEASE" (a).
Insert tool as deeply as possible (b) and turn sleeve
in the opposite direction, until any perceptible
mechanical resistance is overcome (c). Caution!
The tool is not yet clamped!
Continue to turn vigorously(you must hear a
"click"), until you cannot turn any further - only
now is the toolsafely clamped.
Notes: The rattling that might be heard after
opening the chuck (depending on the function) can
be eliminated by turning the sleeve into the other
direction.
With a soft tool shank, retightening may be required
after a short drilling period.

7. Maintenance and Cleaning

Always keep thespindle (6)clean and grease it a
bit. (Special grease: Order No.: 6.31800)
Clean (4) keyless chuck:
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.
Vent slots:
The vent slots of the machine should be cleaned
periodically.

8. Troubleshooting

If the trigger button (15) cannot be pressed, check,
if the rotation selector switch (13) is completely in
position R or L.
Electronic signal display (11):
- Fast flashing - restart protection
When power is restored after a power failure, the
machine - which is still switched on - will not start
for safety reasons. To continue operation, switch
the tool off and then on again.

9. 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.
For a complete range of accessories, see
www.metabo.com or the catalogue.
10. Repairs
Repairs to electrical tools must ONLY be carried out
by qualified electricians!
Contact your local Metabo representative if you
have Metabo power tools requiring repairs. See
www.metabo.com for addresses.
You can download a list of spare parts from
www.metabo.com.

11. Environmental Protection

Observe national regulations on environmentally
compatible disposal and on the recycling of disused
tools, packaging and accessories.

Emission values
These values make it possible to assess the
emissions from the power tool and to compare
different power tools. The actual load may be higher
or lower depending on the operating conditions, the
condition of the power tool or the accessories.
Please allow for breaks and periods when the load
is lower for assessment purposes. Arrange
protective measures for the user, such as
organisational measures based on the adjusted
estimates.
Vibration total value (vector sum of three directions)
determined in accordance with EN 60745:
a = Vibration emission value (hammer
