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(3-5mm) 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 (3) 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 Worx customer service agent or
Worx approved service agent.
CAUTION: Do not touch the ground with
the chain. Ensure safety clearance of
12”.
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 packs are shipped 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 may become too hot to permit charging.
Allow time for the battery to cool down before
recharging.
Note:
Always fully charge the two batteries at same
time. More details can be found in charger’s manual.
4. TO REMOVE OR INSTALL BATTERY PACK
(See Fig. I)
Depress the battery pack release button to remove
the 2 battery packs from your tool. After recharging,
insert the 2 battery packs into the battery ports. A
simple push and slight pressure will be sufficient
until a click is heard. Check to see if the battery is
fully secured.
Note:
• When removing the battery pack, hold it
firmly to avoid dropping and injury.
