Cordless Chainsaw 
EN
TENSIONING CHAIN (See Fig. E1, E2)
NOTE: New saw chains will stretch. Check the chain tension 
frequently when first used and tighten when the chain 
becomes loose around the guide bar.
WARNING: 
  Removing the battery pack 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 Chainsaw on any suitable flat surface.
2.   Turn the chain tensioning knob clockwise until it is hand 
tight.
  NOTE: The tension is automatically increased while the 
chain tensioning knob is being turned in a clockwise 
direction. The built-in ratchet mechanism prevents the 
chain tension from loosening.
3.   Tilt the saw forward (See E1) where the guide bar tip is 
pushed in an downward direction. This will remove slack 
from the chain.
4.   Fully tighten the chain tensioning knob by turning it 
clockwise.
5.   Double check the tension set by the automatic chain 
tensioning knob. The correct chain tension is reached 
when the chain can be raised approx. Half the drivelink 
depth from the guide bar in the center. This should be 
done by using one hand to raise the chain against the 
weight of the machine. (See Fig. E2) 
  NOTE: The chain is properly tensioned when it can be 
lifted off of the Guide Bar and the drivelink is within the 
rail of the Guide Bar.
  NOTE: The chain will stretch while cutting and lose 
proper tension. When the chain becomes loose, 
completely unscrew the chain tensioning knob or turn 
the knob around three full turns in a counter-clockwise 
direction, then retighten the chain tensioning knob to 
properly reset the chain tension by repeating Steps 1-4 
listed above.
LUBRICATION (See Fig. F)
IMPORTANT The Chainsaw is not filled with oil. 
It is essential to fill with oil before use. Never 
operate the Chainsaw 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
WARNING: Removing the battery pack before 
filling the oil tank.
1.   Set Chainsaw on any suitable surface with oil filler cap 
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 tank is full.
4.   Avoid dirt or debris entering oil tank, refit oil filler cap and 
tighten by turning clockwise until hand tight.
IMPORTANT To allow venting of the oil tank, 
small breather channels are provided between 
the oil filler cap and the strainer, to prevent 
leakage, and ensure machine is left in a horizontal 
position when not in use.
It is important to use bar and chain lubricant (not 
provided) that is formulated to perform over a wide 
temperature range with no dilution required.  This can 
be found at the location where you purchased this saw 
or your local hardware store. Do not use dirty, used or 
otherwise contaminated oils. Damage may occur to 
the bar or chain.Use of non approved oil will void the 
warranty.
Do not swallow. If swallowed, call a physician 
immediately. Keep out of reach of children. Store away 
from heat or open flame.
CHECKING THE AUTOMATIC OILER
Proper functioning of the automatic oiler can be checked 
by running the Chainsaw and pointing the tip of the 
guide chain bar 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 
WorxNITRO
 
customer service agent or 
WorxNITRO
 approved service 
agent.
CAUTION Do not touch the ground with the 
chain. Ensure safety clearance of 40cm.
OPERATION 
1. BEFORE USING YOUR CORDLESS TOOL
WARNING! The charger and battery pack are 
specially designed to work together so do not 
attempt to use any other devices. Never insert or 
allow metallic objects into your charger or battery pack 
connections because of an electrical failure and hazard will 
occur.
NOTE: Your battery pack is UNCHARGED and you must 
charge once before use.
The battery charger supplied is matched to the Li-ion 
battery installed in the machine. Do not use another battery 
charger.
2. CHECKING THE BATTERY CHARGE CONDITION (See 
Fig. G) 
The battery level can be known from the battery indicator 
light by pressing the button beside the lights.
NOTE Fig. G only applies for the battery pack with battery 
indicator light.
3. CHARGING YOUR BATTERY PACK (See Fig. H)
The Li-ion battery is protected against deep discharging. 
When the battery is empty, the machine is switched off by 
means of a protective circuit. Each battery must be fully 
charged before the first use.
In a warm environment or after heavy use, the battery pack
