IMPORTANT:
• Pressing the saw chain hard against the wood
not only tires the operator quicker but also
quickens the wear of the saw chain and guide
bar.
• If wood cannot be cut without pressing the
saw chain hard against it, this indicates that
the saw chain is becoming dull. In such cases,
either sharpen the saw chain or replace it
with a new chain.

encountering difficulties in cutting. The method
described below makes cutting thick branches easier:

lower side of the desired area of the branch to be
cut.
2. Then, start cutting from the upper side of the
branch.
3. hereafter, cut into the
lower side where the
desired area of branch is
to be cut.
4. Finally, cut through from
the upper side where the
branch is to be cut, cut-
ting the branch off.

the main unit of the pruner and cause
a malfunction of the pruner.
Saw chain tension adjustments
• When using the pruner be sure to turn
the engine off before making any
inspections or any adjustments.
• Do not make any adjustments when the
guide bar or saw chain is still hot imme-
diately after using the pruner. Wait
until it has cooled before making any
adjustments.
1. Turn the nut on the chain cover once to loosen it.
2. Lift up the leading edge of the guide bar and turn
the regulating screw to tighten the saw chain.
Turning the screw clockwise tightens the saw
chain, whereas turning it counterclockwise looses
the saw chain.
3. Securely tighten the nut on the chain cover.
4. Verify that the saw chain on the central section of
the guide bar can be lifted with fingers 3 to 4 mm
off the guide bar.
