Guide bar and saw chain installation
1. Slot the saw chain in the groove of the guide bar,
ensuring that the cutter section of the saw chain is
facing the front.
2. Engage the saw chain into the sprocket.
3. Insert the groove of the guide bar into the pruner’s
main unit and adjust the regulating screw to ensure
that the adjuster is inserted in the circular hole of
the guide bar.
4. Put the chain cover on and temporarily screw it in
place using a nut, to the extent that the guide bar
can be moved.
5. Lift up the leading edge of the guide bar and using
a screw driver turn the regulating screw clockwise
to tighten the saw chain until the saw chain
slightly touches the lower side of the guide bar.
6. Securely tighten the nut on the chain cover, using
the box spanner, provided as an accessory with the
product.
7. Verify that the saw chain on the central section of
the guide bar can be lifted by the fingers 3 to 4
mm off the guide bar.
CAUTION
• In order to prevent cuts, be sure to
wear gloves when handling the guide
bar and saw chain.
• Maintain the tension of the saw chain
properly at all times.
• If not enough tension is applied to the
saw chain it can easily be dislodged
when the saw chain is in motion.
• If too much tension is applied to the
guide bar, saw chain and clutch may
wear prematurely as a result.
