DESCRIPTION
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.
Safety Devices
The one-man saw is fitted with a number of
safety devices, which are described under the
headings below.
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.
WARNING!
The one-man saw must not be
started if any of the safety
devices have been removed,
are defective, or are not
working.
Bandsaw Blade Guard (upper)
(20)
The upper section of the bandsaw blade runs in
a slot.
