Husqvarna SMB 70, SMB 70 E manual Safety Devices

DESCRIPTION

Safety Devices

The one-man saw is fitted with a number of safety devices, which are described under the headings below.

!WARNING!

The one-man saw must not be started if any of the safety devices have been removed, are defective, or are not working.

Band Wheel Guard (21)

The band wheels are protected from contact by a cover on each side. Each cover is equipped with a safety key that cuts the mains power to the start switch for units with an electric motor and short-circuits the petrol engine when the covers are removed. There are 3 rubber straps on the guard to allow easy dismantling and assembly when changing the bandsaw blade. The safety key activates a safety switch when the covers are fitted. The rail stop (FIG. 14A) prevents the bandsaw carriage from rolling off the rails.

Bandsaw Blade Guard (upper) (20)

The upper section of the bandsaw blade runs in a slot.

Bandsaw Blade Guard (lower) (23)

The part of the bandsaw blade that is not in the log when cutting should be covered by the adjustable guard.

Bandsaw Blade Brake (FIG. 16)

The bandsaw is equipped with an integrated brake/clutch (A) that stops the band wheel in order to quickly stop the band wheel when the handlebar controls (4) are released.

Starter, Electric Motor (FIG. 17)

The electrically powered saw is equipped with a main switch (35), safety switch connector with phase inverter (31), contact for safety switch (A), and start switch (33). The motor is started with the green start switch and stopped with the red stop switch (32). The electric motor stops when not in use for longer periods or when sawing is completed. The starter is equipped with a 0-volt trigger. This means that the sawmill’s electric motor must be restarted after a power outage.

Stop Switch, Petrol Engine (14)

On the petrol engine, the stop switch is located on the engine body and with electric start the engine is stopped with the key.
