Installing the Blade
1. Loosen blade fixing screw 4 and re-
move chain wheel cover 6.
2. Insert blade 2 with the central longitudi-
nal hole over central blade guide 16.
Fitting the saw chain
1. Lay out saw chain 1 such that the bev-
elled cutting edges of the chain links
point in a clockwise direction. See the
detailed illustration.
2. Place saw chain 1 in blade groove 2
and on chain wheel 18.
3. Replace chain wheel cover 6 and screw
on blade fixing 4. Blade fixing screw
4 is simply to be tightened lightly by
hand.
Hole 20 on the blade is the holder for
chain tensioning pin 21.Thread 19 is the
holder for blade fixing screw 4.
Ensure that chain tensioning pin
21 is positioned in hole 20 on the
blade.The pin must be completely
inserted into the hole.
Tensioning the saw chain
The tension of saw chain 1 is important
both for your safety and for the function of
the high pruning saw. A correctly ten-
sioned saw chain will increase the lifetime
of your equipment.
Saw chain 1 is correctly tensioned if it can
be pulled around blade 2 by hand (wear-
ing gloves) without sagging.

When the saw chain is tensioned with 9 N
(approx. 1 kg), the gap between the saw
chain and the guide rail may not be more
than 2 mm.
1. Turn blade fixing screw 4 anticlockwise
to slightly loosen blade 2.
2. Set the tension of saw chain 1 using
chain tensioning device 5.
Turn this quick tensioning device clock-
wise to increase the tension.
In the same way, the tension of saw
chain 1 can be decreased by turning
anticlockwise.
3. Turn blade fixing screw 4 clockwise to
retighten blade 2.
Where saw chain 1 has been newly ten-
sioned, readjust the chain tension after a
short period in operation.
Check the chain tension before
each use of the high pruning saw.
Chain lubrication
Blade 2 and saw chain 1 must al-
Blade 2 and saw chain 1 must al-
ways be oiled. Non-observance of
this will result in increased wear on
the blade and saw chain.
The high pruning saw is equipped with
an oil automatic system. As soon as the
motor is speeded up, the oil also flows
faster to the chain bar 2.
