Handle cover cannot be separated from switch box without removing lock lever of safety lock mechanism. Remove lock lever as illustrated in the “Disassembling safety block mechanism” procedure.

1. Remove handle cover. Now relay can be replaced.

2. Do not forget to mount clamp plate and felt ring 6 when assembling switch section. And do not remove sponge sheet from handle cover, when mounting it to switch box. Because these three parts protect the machine against saw dust.

Do not push the insulated connector into the motor housing through the punched hole.

The lead wire of the soft start circuit has to be held with the lead holder.

The lead wires which are put on the edge of the field must be bundled with varnish tetron tubes by separating them into two groups. A maximum of four lead wires can be in each bundle.

Before securing the clamp plate, put the lead wires between rib A and B.

When a line filter is used (exclusively for low voltage in Great Britain), pass the following lead wires through the line filter:

Field lead wire (orange)

Soft start lead wire (Purple)

Place the line filter in the space illustrated in the wiring diagram.

Put the insulated connectors into the space between the relay and the inner wall, or push them into the punched hole.

Be careful not to pinch the lead wires of the light circuit between rib B and the relay, when the fluorescent job light is installed.

When putting lead wires onto the relay, do not put them on this area.

Put the lead wires connected to the relay through the punched hole, between the boss and rib A.

Put the noise suppressor into the space between the relay and the inner wall, or push it into the punched hole when it is used.

Put lead wires in the lead holder.

Put the insulated terminal in the space shown in the wiring diagram illustration.
