Indicator Lamp
N
The indicator lamp (1) comes on in
certain operating conditions:
It glows continuously when the chain
brake is engaged (chain locked) or the
overload circuit breaker has interrupted
the power supply.
The indicator lamp flashes briefly to
confirm it is functioning every time the
motor is switched on.
Overload Circuit Breaker
The overload circuit breaker cuts off the
power suppy in the event of mechanical
overload due to, e.g.
–
excessive infeed force
–
"lugging down" the motor
–
pinching the saw chain in the cut
If the overload circuit breaker has cut off
the power supply:
N
Pull the guide bar out of the cut.
N
Wait for the overload circuit breaker
to cool down. The machine resets
automatically and is ready for
operation within a brief period.
N
If necessary, disengage the chain
brake – see "Chain Brake".
If the motor does not start when you
switch on, the overload circuit breaker
has not cooled down sufficiently.
When the motor restarts:
N
Run the motor off-load for about 15
seconds. This cools the motor and
helps prevent the overload circuit
breaker tripping again.
During operation
N
Check level in chain oil tank.
N
Top up with chain oil when the "min"
mark is reached, or earlier – see
"Filling the Chain Oil Tank".
Check chain tension frequently
A new chain has to be retensioned more
often than one that has been in use for
some time.
Chain cold
Tension is correct when the chain fits
snugly against the underside of the bar
and can still be pulled along the bar by
hand. Retension if necessary – see
"Tensioning the Saw Chain".
Chain at operating temperature
The chain stretches and begins to sag.
The drive links must not come out of the
bar groove – the chain may otherwise
jump off the bar. Retension the chain –
see "Tensioning the Saw Chain".
NOTICE
The chain contracts as it cools down. If it
is not slackened off, it can damage the
drive shaft and bearings.
