"Quick” clamping nut (9).
9.3 Securing/releasing the clamping nut
(depending on equipment)
Securing
Turn the clamping nut (10) onto the spindle:
Thin grinding wheels (A):
Move collar of clamping nut upwards, so that the
grinding wheel can be safely clamped securely.
Thick grinding wheels (B):
Move collar of clamping nut downwards, so that
the clamping nut can be fitted securely.
Lock the spindle in position. Fit the pin spanner
(11) onto the clamping nut (10) and turn clockwise
to tighten.
Releasing
Lock the spindle in position, slacken off the
clamping nut with the pin spanner (11) and screw
off.
10 Maintenance
Remove the plug from the mains supply socket
before undertaking any maintenance work.
Motor cleaning: blow compressed air through the
rear ventilation slots of the machine regularly,
frequently and thoroughly. Here, the machine
must be held firmly.
From time to time blow any dust away from the
handle setting button (with the button held down,
in all three positions).
The auto-stop carbon brushes must only be
replaced in an accredited workshop. Have checks
and maintenance carried out by Metabo
Authorized Services.
11 Troubleshooting
Inrush currents cause short-time voltage drops.
Under unfavourable power supply conditions,
other equipment may be affected. If the system
impedance of the power supply is lower than
0.2 Ohm, disturbances are unlikely to occur.
12 Accessories
Use original Metabo accessories only.
Your Metabo dealer will supply you with any
accessories you may require.
To assist in selecting the correct accessories,
make sure that you take a note of the exact model
of your tool for your dealer.
