8.4 Switch/Motor Protection/Motor Brake

The magnetic switch does not engage if not connected

to power mains. It disengages in the event of a power

failure (no-volt release). When the power is restored the

machine has to be started again.

The built-in motor protection relay switches the motor off

in case it becomes too hot. If this has happened let motor

cool down for at least 10 minutes before starting again.

Three-phase motors are equipped with a mechanical

brake, which is designed for a long service life. If the

blade needs more than 10 sec. to come to a complete

standstill the brake has to be replaced. Check with your

metabo dealer for replacement.

An inoperative motor brake increases danger of injury!

9.2 Blade Change

Disconnect from power before servicing!

Remove chip case lid and loosen arbor bolt. Remove

arbor bolt and counter flange, then take off blade.

Note: Arbor bolt has L.H. thread, turn clockwise to

loosen.

Before installing new blade clean blade seat and apply a light coat of oil to the arbor bolt.

Be sure that teeth are pointing in direction of rotation. Tighten arbor bolt carefully. Replace chip case lid and nuts

securing it in place.

Operation without chip case lid in place may cause personal injury!

9.0 Operation/Settings

9.1 Riving Knife Setting

Disconnect from power before servicing!

The riving knife prevents the work from closing behind the blade, thus stalling it and causing kickback.

Set riving knife as close as possible against the blade. The gap between riving knife and blade must not exceed

10mm/3/8 “. Do not set top of riving knife lower than 2mm-5/64” below the blade’s crown.
