Operation/Settings - Metabo BKS 400 Assembly & Operating Instructions

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!

9.0 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.
9.2 Blade Change
Disconnect from power before servicing!
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!
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.
