at the mid point of the
underside of the bar.
The maximum distance
between the driving links
and the bar should be
6.5mm.
Note. Ensure the unit is
unplugged when making
any adjustments to the chain
and bar.
CAUTION. A new chain will stretch after just a few minutes
of use. Check and, if necessary, re-adjust the chain tension.
A loose chain causes rapid wear to both the chain and the
guide bar and could derail causing a major safety hazard.
Chain tension
The chain should not be too
loose, but you should be
able to lift it off the guide bar
a few millimetres. Use the
chain tensioner to tension
the chain.
Always pull the power plug
before undertaking any
maintenance work. The allen
head screw of the chain
tensioner is at the front of the pole saw’s hear next to the
guide bar. Turning it clockwise tightens the chain, turning it
counter-clockwise slackens the chain. Beware of the sharp
edges of the saw chain.
Working with the pruner
Do not work with an angle higher than 60°. The pole saw
will work under higher degrees, but there is the danger of
being injured by branches falling without warning.
Keep an eye at the ground while working to avoid tripping
over fallen branches.
Never use the pole saw without oil, use biodegradable
chainsaw oil.
To operate the pruner push forward the safety switch and
then pull the switch.
The pruner is equipped with a low-kickback chain and it was
also done everything from an engineering point of view to
keep kickback low. Nevertheless, some kickback can not
be avoided when cutting with the upper tip of the blade. Be
prepared for some kickback when using this area of the
blade or hitting another branch with this area. Always hold
the unit firmly in both hands.
Thin branches can be cut off with one single cut. To prevent
the branch from slivering and buckling the branch should be
cut off in several pieces.
When cutting off lager branches, you should first cut into
the branch form below. First cut into the branch from below
outside the place where you intend to cut off the branch.
The cut should go from one third to halfway through the
branch. This prevents the branch from buckling when you
cut into the branch from the top outside the first cut. Last cut
off the stump with one clean cut. You might want to seal the
cut with a suitable compound.
Chain sharpening and maintenance
WARNING. Always ensure that the tool is switched
off and the plug is removed from the power point before
making any adjustments or maintenance procedures.
The chain requires sharpening when the chain saw does
not cut appropriately, this operation is performed as follows.
1. Extend the chain bar.
2. Fix the bar in a vice so that the chain can slide.
