TENSIONING CHAIN
New saw chains will stretch. Check chain 
tension frequently when first used and tighten 
when Chain becomes loose around the Guide 
Bar (7).
WARNING: Remove the battery 
from the tool before adjusting saw 
chain tension.
WARNING: Cutting edges on chain 
are sharp. Use protective gloves 
when handling chain.
WARNING: 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 (10) 
clockwise until it is hand tight. The tension 
is automatically set while the Chain 
Tensioning Knob is being tightened.
  The ratchet mechanism (a) prevents the 
chain tension from loosening. (See Fig. F1)
3.  Double check the tension set by the 
automatic  Chain Tensioning  Knob. The 
correct chain tension is reached when the 
Chain (8) can be raised approx. 3-6mm 
from the Guide Bar (7) in the center (the 
chain links should just remain in the bar 
track). This should be done by using one 
hand to raise the chain against the weight 
of the machine. (See Fig. F2)
  Use a screwdriver to move chain around 
Guide Bar to ensure kinks do not exist. The 
chain should rotate freely. (See Fig.  F3 )
4.  When the chain looses, unscrew the Chain 
Tensioning Knob absolutely and then 
Screw on the cover plate with the locking 
knob tightly again.
LUBRICATION
IMPORTANT: He 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.
NOTE: Chain life and cutting capacity depend 
on optimum lubrication.  Therefore, the chain 
is automatically oiled during operation. 
Filling oil tank:
1.   Set chain saw on any suitable surface with 
Oil Filler Cap (4) facing upward.
2.  Clean area around the Oil Filler Cap with 
cloth unscrew cap.
3.  Add bar and chain oil until reservoir is full. 
ISO VG32 Bar and chain oil of any brand 
can be used.
4.  Avoid dirt or debris entering oil tank, refit 
the Oil Filler Cap and tighten.
IMPORTANT: To allow venting of 
the oil reservoir, small breather 
channels are provided between the oil 
filler cap and the strainer, to prevent 
leakage ensure machine is left in a 
horizontal position (Oil Filler Cap (4) 
uppermost) when not in use.
It is important to use only the 
recommended oil to avoid damage to the 
chain saw. Never use recycled/old oil. 
Use of non approved oil will invalidate 
the warranty.
CHECKING  THE AUTOMATIC OILER
Proper functioning of the automatic oiler can 
be checked by running the chain saw and 
pointing the tip of the Guide Bar (7) towards a 
piece of cardboard or paper on the ground. 
If an increasing oil pattern develops on the 
cardboard, the automatic oiler is operating 
fine. If there is no oil pattern, despite a full 
oil reservoir, contact WORX customer service 
agent or WORX approved service agent.
CAUTION: Do not touch the ground 
with the chain. Ensure safety clearance 
of 30cm.
