MAINTENANCE, REPAIR AND

Servicing of double-insulated
appliance
This electric chainsaw is double-
insulated. In such an appliance, two
systems of insulation are provided
instead of grounding. No grounding
means are provided, nor should means
for grounding be added to the appliance.
Servicing a double-insulated appliance
requires extreme care and knowledge of
the system, and should be done only by
qualified service personnel.
!Warning!
Replacement parts for double-insulated
appliance must be identical to the parts
they replace.
!Warning!
Use only STIHL replacement parts for
maintenance and repair. Use of parts
manufactured by others may cause
serious or fatal injury.
!Warning!
Never operate a chainsaw that is dam-
aged, improperly adjusted or not com-
pletely or securely assembled. Follow
the maintenance and repair instructions
in the appropriate section of your
Owner's Manual, especially those in the
chapters " Mounting the Bar and Chain"
"Maintaining and Sharpening" and
"Chain Brake".
!Warning!
Always stop the motor, disconnect the
plug from the power supply and ensure
that the chain is stopped before making
any adjustments, maintenance or repair
work, changing the saw chain or
cleaning the saw. Do not attempt any
maintenance or repair work not
described in your Owner's Manual. Have
such work performed at your STIHL
service shop only.
Keep the chain, bar and sprocket clean;
replace worn sprockets or chains. Keep
the chain sharp. You can spot a dull
chain when easy-to-cut wood becomes
hard to cut and burn marks appear on
the wood. Keep the chain at proper
tension. Tighten all nuts, bolts and
screws before each use.
Only authorized personnel may replace
the power supply cord. A damaged
power supply cord must be replaced by
an identical STIHL replacement part.
!Warning!
In order for the chain brake on your
STIHL chainsaw to properly perform its
function of reducing the risk of kickback
and other injuries, it must be properly
maintained. Like an automobile brake, a
chainsaw chain brake incurs wear each
time it is engaged.
The amount of wear will vary depending
upon usage, conditions under which the
saw is used and other factors. Excessive
wear will reduce the effectiveness of the
chain brake and can render it
inoperable.
For the proper and effective operation of
the chain brake, the brake band and
drum must be kept free of dirt, grease
and other foreign matter which may
reduce friction of the band on the drum.
For these reasons, each STIHL
chainsaw should be returned to trained
personnel such as your STIHL servicing
dealer for periodic inspection and
servicing of the brake system according
to the following schedule:
Heavy usage - every three months,
Moderate usage - twice a year,
Occasional usage - annually.
