8.3 Saw Blade Direction of Rotation

On single-phase machines the saw blade’s direction

of rotation does not need to be checked.

For three-phase machines start saw briefly with all

guards in place and check direction of rotation. If

incorrect interchange two phases by rotating two pins

in the switch by 180°. Remove plug, use screwdriver

with 6mm/1/4" blade to push lock down and turn pins.

To prevent unauthorized use the switch can be blok-

ked with a padlock.

8.2 Connection to Power Mains

Check if voltage of power mains matches with voltage stated on machine’s name plate. This machine must be

earthed while in use to protect the operator from electric shock.

Models BKS400/3.1 kW must be connected to an earthed outlet with a 3-conductor mains lead.

Models BKS 450/4.2 kW and 4.75 kW have to be connected to an earthed outlet with a 5-conductor mains lead.

A minimum conductor cross section of 1.5mm /16 AWG is required. For the 3.1kW single-phase motor extension

cords should have a conductor cross section of 2.5mm .

Use of an extension cord with too small a conductor cross section causes voltage drop and consequently starting

problems and excessive heat build-up in the motor.

8.0 Installation

8.1 Setup

This saw must be placed on a firm and level ground. The work area must be kept clear of all waste to provide firm

footing for the operator.

7.1 Mitre Fence Setting

setting screw in or out, as required.

Make trial cut to verify setting.

Loosen mitre scale and adjust so that zero

mark corresponds with mark on vernier scale,

then retighten.
