Saw chain tension 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 counter-clockwise 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.
WARNING
・
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 immediately after using the pruner.
Wait until it has cooled before making any adjustments.
Pruning thick branches
Attempting to cut a thick branch in one go often results in the guide
bar jamming in the branch or otherwise encountering difficulties in
cutting. The method described below makes cutting thick branches
easier:
1. First of all, cut a section slightly away and on the lower side of
the desired area of the branch to be cut.
2. Then, start cutting from the upper side of the branch.
3. Thereafter, 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, cutting the branch off.
IMPORTANT: If the guide bar or saw chain jams into the
branch, do not force it. Widen the cut using a
wedge to remove the pruner and try cutting it
again. Forcing the pruner may damage the main
unit of the pruner and cause a malfunction of the
pruner.

Cutting wood
1. Turn the pruner on full throttle and press the saw chain lightly against the wood to cut.
2. The cutting capacity is reduced when the engine revolution is slowed down and the saw chain is pressed
hard against the wood.
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.
