Safety Devices

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

!WARNING!

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

Saw chain guard (FIG. 17)

A protective loop (8) is installed as a guard over the saw chain.

Chain brake (FIG. 17)

The chain is started with a centrifugal clutch on both the sawmill with the chain saw engine and the electric sawmill. As soon as the engine speed drops, the chain is disengaged and then stops.

Starter electric motor (FIG. 18)

The electrically powered sawmill is equipped with a main switch (A), connector with phase inverter (27) as well as a start button (29) with safety switch (37) and stop button (32). The sawmill stops as soon as the safety switch is released. The starter, which is located on the handlebar (16), is equipped with a 0-volt trigger. This means that the sawmill’s electric motor must be restarted after a power outage.

Stop button chain saw engine (FIG. 19)

On the chain saw engine there is a stop button on the engine body, see the chain saw operator’s manual.

Starter electric motor with feed (FIG. 20)

The starter is equipped with a safety switch (37) and start button (29), with which the saw motor is started. The safety switch must be activated throughout the entire cutting process, as the saw motor and hence the feed stop as soon as the safety switch is released. The feed starts when the start button (30) is activated and controlled variably with the control (31). The saw carriage can be returned by activating the start button, as soon as the saw motor has stopped. The feed then changes direction and returns. The speed is controlled variably with the control (31). The starter is equipped with a phase inverter (27) in the connector.
