direction of the teeth (see Fig. H). The 
cutting direction is inward on the lower 
cutting edge.
9.  With the mounting plate (a) toward the 
motor and holding the chain in place on 
the bar, feed bar and chain into the jaw, 
angling over the bar locating pins (d) and 
engaging the chain on the drive sprocket 
(16) (See Fig I). There is little excess chain 
length, therefore, the chain must be 
properly fitted in the bar slot to provide 
enough extra chain to be pulled over the 
drive sprocket.
10.  Check if all parts are seated properly (See 
Fig J).
11.  Refit and tighten the chain tensioner bolt. 
Note the cam (e) of the tensioner will 
engage the projecting tab (f) of the bar 
mounting plate and push the bar outward 
to tension the chain, check for correct 
tension (See ADJUSTING THE CHAIN 
TENSION).
12.  Close the access cover and remove the 
lock pin.
LUBRICATION
IMPORTANT: The JawSaw is shipped 
with an empty oil tank. It is essential to 
fill with chain oil before use.
Never operate the JawSaw without 
chain oil or an empty tank as this will 
result in poor cutting performance, 
motor overload and possible burn-out.
FILLING OIL TANK:
UNPLUG THE TOOL BEFORE FILLING 
WITH OIL.
1.   Fill oil bottle with bar oil. (See Fig. K)
2.  Rest the JawSaw with the oil filler (6) facing 
upward
3.  Lift the rubber oil filler flap (g) open.
4.  Use bottle to fill oil reservoir. (See Fig. L)
5.  Close the filler flap by pressing the plug 
part of the flap into the oil filler to seal. (See 
Fig. M)
IMPORTANT: Use only the 
recommended oil to avoid damage 
to the JawSaw. Never use recycled/old oil. 
Use of non approved oil will invalidate the 
warranty.
 
CHECKING THE AUTOMATIC OILER
The JawSaw uses a much lower chain speed 
than a conventional chainsaw so it needs 
much less oil. 
However is it very important that it always has 
oil. 
Check the oil tank window and refill as 
necessary.
During operation, periodically check the 
chain and bar. A slight oil presence should be 
visible. If the chain and bar appear completely 
dry, then remove the bar and chain (see 
previous section) to ensure the bar oil hole is 
not blocked.
If the oil hole is clear, there is oil in the tank 
and still no oiling of the chain is visible – 
contact Worx customer service (contact 1-866-
354-9679).
OPERATION
PREPARE YOUR JAWSAW FOR USE
WARNING: Read and understand 
all instructions. Failure to follow all 
instructions listed may result in electric 
shock, fire and/or serious personal injury. 
WARNING: Sharp moving blade. 
To prevent accidental operation, 
ensure that the tool is disconnected from 
the power source before performing the 
following operations, failure to do this 
could result in serious personal injury. 
CAUTION: Sharp moving blade. 
Always wear protective gloves 
when installing or removing the chain, 
the chain is sharp and can cut you when 
it is not running.
ATTACHING EXTENSION CORD 
1.   To prevent disconnection of appliance 
cord, secure extension cord to extension 
cord retainer.
2.  An extension cord retainer is supplied to 
reduce strain on the power cord. To use 
this feature, form a loop at the end of the 
extension cable and bring this through the 
opening at the cable hook and suspend in 
the tension relief at the hook. (See Fig N)
