WARNING! The direction of the saw chain
'cutters' must be as indicated by the arrow
on the pruner head!
g). Make sure the tension pin (B11) is inserted into
the lower hole on the guide bar. (See Fig. 3e)
h). Refit the cover (B2), spring washer (B4) and
slightly tighten the locking nut (B3). (See Fig. 3f)
NOTE: The saw chain (B6) has not yet been
tensioned. Tension the chain as described under
"Saw chain tensioning". After operating the
product for approx. 30min, adjust the chain
3). Saw chain tensioning
Always check the saw chain tension before use,
after first cuts and regularly during use,
approx. every five cuts. After initial operation, new
chains can lengthen considerably. This is
normal during the break-in period and the interval
between future adjustments will lengthen
quickly.
WARNING! Always switch the product off
and disconnect the spark plug connector
before adjusting the saw chain tension!
The cutting edges of the saw chain are sharp.
Always wear protective gloves when
handling the chain!
Always maintain proper chain tension! A loose
chain increases the risk of kickback! A
loose chain may jump out of the guide bar groove!
This may injure the operator and
damage the chain! A loose chain will cause rapid
wear to the chain, guide bar and
sprocket!
Tensioning the chain too tightly will
overload the engine and cause damage,
and insufficient tension can cause chain
derailing, whereas a correctly tightened chain
provides the best cutting characteristics and
prolonged working life! The chain life
mainly depends upon sufficient lubrication and
correct tensioning!
a). Lift up the tip of the guide bar (B7) and keep it
there as you adjust the tension.
b). Turn the tension screw (B12) clockwise until the
chain "tie straps" are just touching the
bottom edge of the guide bar (B7). (See Fig. 4a)
c). Check the chain tension using one hand to lift
the saw chain (B6) against the weight of the
product. The correct chain tension is achieved
when the saw chain can be lifted by approx. 2-
4mm from the guide bar (B7) in the centre. (See Fig.
4b, 4c)
d). Turn the locking nut (B3) to tighten the cover (B2)
completely.
4). Chain lubrication Filling
WARNING! The product is not filled with
chain oil. It is essential to fill the product
with chain oil before using it! Never operate
the product without chain oil as this will
result in extensive damage to the product!!
Operating the saw chain dry or with too little chain
oil will decrease cutting efficiency,
shorten the product life span and cause rapid wear
to the saw chain and guide bar from
overheating! Insufficient chain oil is evident by
smoke or bar discoloration! Adequate
lubrication of the saw chain during cutting
operations is essential to minimise friction
with the guide bar!
a). Set the product on any suitable surface with the
chain oil tank cap (B1) facing upwards.
(See Fig. 5a)
b). Unscrew and remove the tank cap (B1), then
add the lubricant into the tank. We
recommend using environmentally-friendly chain
oil specifically intended to be used with this
product.
c). Use a proper funnel with a filter to prevent
debris entering the tank and to avoid spilling and
overfilling the tank. Do not overfill and leave
approximately 5 mm of space to the lower edge to
allow the lubricant to expand. (See Fig. 5b)
d). Wipe up spilled fuel with a soft cloth and refit
the chain oil tank cap (B1).
