8 ASSEMBLY
WARNING! Read all the instructions carefully!
Don’t connect the product to
the power supply until it is completely assembled! Always wear gloves
during assembly
8.1 Chain and guide bar
 Use only the guide bar (4) and saw chain (3) according to the technical data of the
product.
 Place the product on a suitable flat surface with the cover (9) facing upwards.
 Loosen the cover (9) by turning the locking wheel(7) anticlockwise (Fig.3,a) and remove it.
 Spread the saw chain (3) out with the cutting edges of the chain pointing in the rotational
direction and slide the chain into the groove around the guide bar (4) (Fig. 4).
WARNING! Always use a saw chain designed as “low- kickback” or a saw
chain which meets the low-kickback requirements! A standard saw chain (a
chain which does not have the kickback reducing guard links) should only
be used by an experienced professional operator! Nevertheless, a low-
kickback saw chain does not completely eliminated kickback! A low-
kickback or “safety” chain should never be regarded as complete
protection against injury! Therefore always use a low-kickback saw chain in
conjunction with other kickback protection devices such as the front
guard/chain brake!
 Align the guide bar (4) and saw chain (3) assembly with the drive sprocket (23) and bolt
(21). Lay the saw chain around the drive sprocket and then lower the guide bar to install it
to the bolt (Figs. 5, 6).
 Replace the cover(9) and slightly tighten the locking wheel (7) (Fig. 7, b). Do not tighten
the locking wheel completely; saw chain tensioning is required first.
8.2 Saw Chain Tensioning
Always check the saw chain tension before use, after first cuts and regularly during use,
approximately 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! Unplug the product from the power source 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 motor
and cause damage, and insufficient tension can cause chain derailing,
