Switch/Motor Protection/Motor Brake, Blade Change

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!

9.0Operation/Settings

9.1Riving 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.

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!
