Using The Chain Saw - Stihl MSE 141 C Instruction Manual

5 IMPORTANT SAFETY INSTRUCTIONS
– Make sure the power supply cord and extension cord
are positioned and secured or marked so that they
will not be stepped on, tripped over, come in contact
with sharp objects, moving parts, or otherwise be
subjected to damage or stress.
￭ To reduce the risk of electric shock:
– Use only extension cords that are intended for
outdoor use, identified in the U.S. by the following
marking: "Suitable for use with outdoor appliances.
Store indoors while not in use."
– The chain saw must be connected to an electrical
outlet equipped with a Ground Fault Circuit
Interruptor (GFCI) or Residual Current Device (RCD)
with a maximum differential tripping current of
30 mA.
￭ This power tool has a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only
one way. To reduce the risk of electric shock:
– Do not change the plug in any way.
– If the plug does not fit fully in the outlet, reverse the
plug. If it still does not fit, contact a qualified
electrician to install the proper outlet.
￭ Overloading an extension cord can result in overheating
and fire. To reduce these risks:
– Be sure to use an extension cord heavy enough to
carry the current your electric saw will draw. Read
and follow the minimum wire size requirements for
120 Volt appliances set out in, @ 20.2.
– Use of an extension cord not meeting the minimum
wire size will cause a drop in wire voltage and result
in a loss of power and overheating.
– Never use an extension cord with a wattage or
electrical rating lower than the wattage or electrical
rating on your chain saw's rating plate.
– Never use an extension cord if the blades on its plug
are different from the blades on the power tool plug
in number, size or shape.
– Never connect more than one chain saw or other
device to a single extension cord.

Using the Chain Saw

5.6.1 Before Operation
WARNING
￭ Misuse or unauthorized use may result in personal injury
and property damage.
– Use the chain saw only as described in this
instruction manual.
￭ For proper assembly of the bar and chain:
– Read and follow the instructions on mounting the
guide bar and chain, @ 10.2.
￭ The chain, guide bar and sprocket must match each other
in gauge and pitch. Before mounting or replacing:
– Read the information on guide bar and chain
combinations, @ 22.
– Read and follow the instructions on kickback and
other reactive forces, @ 6.
– Select the shortest bar that will meet your cutting
needs. Longer bars add weight and may be more
difficult to control.
￭ Proper tension of the chain is extremely important to
maximize cutting performance and reduce the risk of
personal injury from chain breakage, derailment or
reactive forces:
– Read and follow the chain tensioning instructions,
@ 10.3.
– Always make sure the chain sprocket cover is
tightened securely after tensioning the chain in order
to secure the bar. Never start the chain saw with the
chain sprocket cover loose or missing.
– Check chain tension once more after tightening the
chain sprocket cover.
– After adjusting the chain, let the motor run for a
minute or two, then switch the motor off and engage
the chain brake. Disconnect the chain saw from the
power supply and recheck chain tension.
