7. Please make sure the tension wheel (20) is in the position as shown
in Fig.9, or else rotate it anticlockwise to make the mark on the side
cover (12) be aligned with the mark on the tension wheel (20). ( Fig.9)

8. Refit the cover (12) , fit the rear of cover then front, ensure pin
is located in position. Slightly tighten the locking wheel (19) (Fig.
10). Do not tighten the locking wheel (19) completely, saw chain
tensioning is required first.
NOTE: The saw chain (14) has not yet been tensioned.
Tension the chain as described under “Saw chain
tensioning”. After operating the product for approx. 1
hour, adjust the chain tension again.
Saw chain tensioning
Always check the saw chain tension before use, after the first cuts and
regularly during use, approx. every five cuts. Upon 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! Disconnect the product from the power
supply 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
tension wheel (19) tightened - it must be loosened first.
1. Place the product on a suitable flat surface with the side cover (12)
facing upwards.
2. Check the chain tension using one hand to lift the saw chain (14)
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 (13) in the centre (Fig.11, 12).
