WARNING! Disconnect the spark
plug connector before adjusting
saw chain tension!
The cutting edges of the saw chain
are sharp! Always wear protective
gloves when handling 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 motor 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!
NOTE: The chain tension can not
be adjusted with the retaining nut
tightened - they must be loosened
first.
1. Lift up the tip of the guide bar (7) and keep it
there as you adjust the tension (Fig. 8).
2. Turn the tension screw (16) until the chain ‘tie
straps’ are just touching the bottom edge of the
guide bar (7) (Fig. 9, 10).
3. Lift up the tip of the guide bar (7) and tighten
the retaining nut (10).
4. Pull the saw chain (6) along the top of the
guide bar (7) by hand from one end to the other,
several times. The chain should feel tight but still
move freely.
Tension test
1. Check the chain tension using one hand
to lift the saw chain (6) against the weight
of the product. The correct chain tension is
achieved when the saw chain can be lifted by
approximately 2 - 4 mm from the guide bar (7) in
the centre (Fig. 11, 12).
2. Adjust the tension if you find that the chain
saw is too loose or tight.
Chain lubrication
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!
1. Place the product on a stable, level surface
with the oil tank cap (26) facing upward. We
recommend laying a non-flammable sheet under
the product.
2. Unscrew and remove the oil tank cap (26) (Fig.
13).
3. Fill suitable lubricant into the tank using an oil
funnel fitted with a filter to avoid debris entering
the tank. Do not overfill and leave approximately
5 mm of space between the top of the oil and the
inside edge of the tank to allow for expansion (Fig.
