Overload Cutout; Operating Instructions - Stihl HTE 60 Instruction Manual

Overload Cutout

The unit is equipped with an overload
circuit breaker
which 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:
Pull the guide bar out of the cut.
N
Wait about 3 minutes for the
N
overload circuit breaker to cool
down.
Do not switch on the unit during this
period because you will otherwise
prolong the required cooling time.
Once the motor starts:
Run the unit for about 15 seconds
N
off load. This helps cool the motor
windings and considerably delays
renewed tripping of the overload
circuit breaker.

Operating Instructions

During Operation
Check the oil level regularly
Never allow the oil tank to run dry.
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".
The chain contracts as it cools
down. If it is not slackened off, it
can damage the gear shaft and
bearings.
After Finishing Work
Slacken off the chain if you have
N
retensioned it at operating
temperature during cutting work.
Always slacken off the chain after
finishing work. The chain
contracts as it cools down. If it is
not slackened off, it can damage
the gear shaft and bearings.
Storing for a long period
