B = Pushback
Pushback occurs when the chain on the
top of the bar is suddenly stopped when
it is pinched, caught or encounters a
foreign object in the wood. The reaction
of the chain may drive the saw rapidly
straight back toward the operator.
Pushback frequently occurs when the
top of the bar is used for cutting.
To Avoid Pushback
1. Be alert to forces or situations that
may cause material to pinch the
chain at the top of the bar.
2. Do not cut more than one limb at a
time.
3. Do not twist the bar when
withdrawing it from an underbuck
cut because the chain can pinch.
MAINTENANCE, REPAIR AND
STORING
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any
nonroad engine repair establishment
or individual. However, if you make a
warranty claim for a component
which has not been serviced or
HT 56 C
maintained properly or if
nonapproved replacement parts were
used, STIHL may deny coverage.
Warning!
Use only identical STIHL replacement
parts for maintenance and repair. Use of
non-STIHL parts may cause serious or
B
fatal injury.
Strictly follow the maintenance and
repair instructions in the appropriate
sections of your instruction manual.
Please refer to the maintenance chart in
this manual.
Warning!
Always stop the engine and make sure
that the chain is stopped before doing
any maintenance or repair work or
cleaning the power tool. Do not attempt
any maintenance or repair work not
described in your instruction manual.
Have such work performed by your
STIHL servicing dealer only.
Wear gloves when handling or
performing maintenance on the cutting
attachment.
Warning!
Use the specified spark plug and make
sure it and the ignition lead are always
clean and in good condition. Always
press spark plug boot snugly onto spark
plug terminal of the proper size. (Note: If
terminal has detachable SAE adapter
nut, it must be securely attached.) A
loose connection between spark plug
terminal and the ignition wire connector
in the boot may create arcing that could
ignite combustible fumes and cause a
fire.
Warning!
Never test the ignition system with the
ignition wire boot removed from the
spark plug or with a removed spark
plug, since uncontained sparking may
cause a fire.
Warning!
Do not operate your power tool if the
muffler is damaged, missing or modi-
fied. An improperly maintained muffler
will increase the risk of fire and hearing
loss. Your muffler is equipped with a
spark-arresting screen to reduce the
risk of fire; never operate your power
tool if the screen is missing, damaged or
clogged. Remember that the risk of a
brush or forest fire is greater in hot or dry
weather.
In California, it is a violation of § 4442 or
§ 4443 or the Public Resources Code to
use or operate gasoline-powered tools
on forest-covered, brush-covered or
grass-covered land unless the engine's
exhaust system is equipped with a
complying spark arrester that is
