ASSEMBLY
WARNING! Do not connect the 
chain saw to the power supply 
before it is completely assembled.
Always use gloves when handling the 
chain.
CHAIN AND GUIDE BAR ASSEMBLY
1.   Unpack all parts carefully.
2.  Place the chain saw on a solid, level 
surface.
3. Use only genuine WORX chains 
designed for Guide Bar.
4.  Slide the Chain (10) in the slot around the 
Guide Bar (9). Ensure the Chain is in correct 
running direction by comparing it to the 
Chain Direction Symbol (16) found on the 
saw body. Ensure the Bar Tensioning Plate 
(22) is facing outwards. (See Fig. A)
5.  Fit the Chain onto the Drive Sprocket (15), 
so that the Fastening Bar Bolt (19) and 
the two Bar Locating Tabs (20) on the Bar 
Clamp (18) into the keyway of the opening 
on the Guide Bar (9). (See fig. B )
6.  Check to see if all parts are seated properly. 
(See Fig. C )
  NOTE: Chain should rotate freely and 
be free of kinks.
7.   Fit the Chain Cover (12) and tighten 
the Chain Cover by turning the Chain 
Tensioning Knob (11) clockwise until it is 
tight. (See Fig. D)
WARNING!  The chain is not 
yet tensioned. Tensioning the 
chain applies as described under 
“TENSIONING CHAIN”. The chain now 
needs to be inspected to make sure it is 
properly tensioned.
TENSIONING CHAIN (See Fig. E)
NOTE: New saw chains will stretch.  Check the 
chain tension frequently when first used and 
tighten when the Chain (10) becomes loose 
around the Guide Bar (9).
WARNING:
•   Unplug chain saw from power source 
before adjusting saw chain tension.
•  Cutting edges on chain are sharp. 
Use protective gloves when handling 
chain.
•  Maintain proper chain tension always. 
A loose chain will increase the risk 
of kickback. A loose chain may jump 
out of guide bar groove. This may 
injure operator and damage chain. A 
loose chain will cause chain, bar, and 
sprocket to wear rapidly.
1.   Place the chain saw on any suitable flat 
surface.
2.  Turn the Chain Tensioning Knob (11) 
clockwise until it is hand tight. The tension 
is automatically set while the Chain 
Tensioning Knob is being tightened.
  The ratchet mechanism prevents the chain 
tension from loosening.
3.  Double check the tension set by the 
automatic  Chain Tensioning  Knob. The 
correct chain tension is reached when the 
Chain (10) can be raised approx. 0.12– 
0.24” (3-6mm) from the Guide Bar (9) in the 
center. This should be done by using one 
hand to raise the chain against the weight 
of the machine. 
4.  The Chain will stretch from use and lose 
proper tension. To turn knob counter 
clockwise (3x), secure the chain cover, and 
retension the chain simply repeat steps 1 - 
3 listed above.
LUBRICATION
IMPORTANT: The chain saw is 
not supplied filled with oil. It is 
essential to fill with oil before use. Never 
operate the chain saw without chain 
oil or at an empty oil tank level, as this 
will result in extensive damage to the 
product.
Filling oil tank:
1.   Set chain saw on any suitable surface with 
Oil Filler Cap (5) facing upward.
2.  Clean area around the Oil Filler Cap with 
cloth and unscrew the cap by turning it 
counter clockwise.
3.  Add bar and chain oil until reservoir is full.
4.  Avoid dirt or debris entering oil tank, 
refit Oil Filler Cap and tighten by turning 
clockwise until hand tight.
