- Press in spindle locking button (8) and hold in
place.
- Screw the tool fixing screw (15) onto the
tensioning spindle and tighten (the spindle locking
knob engages and the tool can be secured).
If the tools used are shorter than the
tensioning spindle, insert the relevant distance
sleeves (18). This is the only way to properly secure
the tool.
8. Maintenance
Disconnect the mains plug or remove the battery
pack from the machine before starting any mainte-
nance 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.
Mains powered machines: The Autostop carbon
brushes must only be replaced in a specialist work-
shop. Always have checks and maintenance work
carried out by Metabo Customer Service.
9. Troubleshooting
9.1
Mains powered machines
- Electronic restart protection
The red electronic signal indicator (2) starts
flashing. If the mains plug is inserted with the
machine switched on, or if the current supply is
restored following an interruption, the machine
does not start up. Switch the machine off and then
back on again.
- The electronic signal indicator (2) lights up
and on-load speed is reduced.
Winding temperature too high. Run the machine in
idling until the electronics signal indicator
switches off.
- High-energy, high-frequency interference
High-energy, high-frequency interference can
cause the machine to deactivate. In this case,
please switch off the machine, disconnect the
plug and then reinsert. As soon as the interference
is reduced, you can continue work.
9.2
Cordless machines
- The electronic signal display (2) lights up and
the load speed decreases. The temperature is
too high! Run the machine in idling until the elec-
tronics signal indicator switches off.
- The electronic signal display (2) flashes and
the machine does not start. The restart protec-
tion is active. The machine will not start if the
battery pack is inserted while the machine is on.
Switch the machine off and on again.
