SPECIAL PRODUCT FEATURES
■ The product is using a special safety wrap-spring
chain break mechanism to stop the chain within one
tenth of a second if the chain brake is engaged or the
trigger is released.
■ The saw chain’s safety drive links are designed to
reduce the risk of kickback.
■ Large chain brake element. In case of a “kickback,
the chain brake is pushed forward” by the back of the
operator’s hand and trips the quick brake of the chain
saw.
■ The lock-off Switch with lock to protect against
unintentional start of the chain saw.
■ The unique Ryobi Live tool indicator™ indicate the
good connection with the power supply.
COMMISSIONING
Assembling the chain bar and saw chain
Pull the mains plug out of the socket. Wear
protective gloves.
■ Unscrew the knob w/nut and remove the sprocket
cover. (Fig. 3)
■ The saw chain should face in the direction of chain
rotation. If they face backwards, turn the loop over.
(Fig. 4)
■ Place the chain drive links into the bar groove. (Fig. 5)
■ Position the chain so there is a loop at the back of
the bar.
■ Hold the chain in position on the bar and place the
loop around the sprocket and make sure it is correctly
mounted. (Fig. 6)
■ Swing the chain tension adjust knob, turn the chain
tensioning bolt clockwise until the saw chain is
correctly tensioned. While the bolt is being tightened,
the chain bar must then be pushed upwards, check
chain tension again, do not tension the chain too
tightly (Fig. 7)
■ Replace the sprocket cover on top and tighten gently
with the knob w/nut.
Note: the saw chain is correctly tensioned if, in the middle
of the cutter, it can be lifted 3mm to 4mm from the cutter
upper edge. Starting the saw again with a new saw chain,
allow it to run in for 2~3 minutes.
WARNING:
After the run-in time, check the chain tension and
retighten the chain if necessary.
Chain&Bar lubricant
The chain saws are delivered without any oil in the oil tank.
Prior to initial operation of the machine, the oil tank must
be lled with lubricating oil.
Ryobi bar and chain lubricant permits chain saw operation
at temperatures as low as -15°C.
To rell the chain & bar lubricant the cap on top of the oil
tank needs to be removed. When lling the oil in, ensure
that no dirt gets into the oil tank. The oil level can be
monitored at the oil sight gauge. One lling of the oil tank
(capacity 0.2l) is sufcient for 25~40 minutes chain saw
operation.
CHECKING CHAIN LUBRICATION
If the saw chain is running dry (i.e. without lubricant), the
cutter and saw chain can be damaged. It is therefore
essential to check the oil level in the oil sight gauge
frequently and every time before starting to use the chain
saw.
WARNING:
Never work without chain lubrication!
To prevent dirt getting inside the tank, clean the oil tank
cap before opening. Check the contents of the oil tank
during sawing work by checking the oil gauge. Close the
oil tank cap tightly and wipe away any spills.
CHAIN BRAKE
The integrated chain brake brings the saw chain to a
standstill within 1/10 of a second if:
■ The chain brake in front is pushed to its forward
(engaged) position or during work with the chain
saw with the back of the operator’s hand (due to a
kickback) pushing the chain brake forward, or
■ The chain saw is switched off by releasing the trigger
If the chain brake is engaged (i.e. the chain brake guard
is pushed to the front) do not try to start the chain saw or
actuate the trigger switch.
WARNING:
Before operating the chain saw, always check
that the chain brake is in perfect working order
(by actuating the hand protection and releasing
the trigger). Have the machine repaired if braking
time is lengthened.
MAINS CONNECTION
WARNING:
Before plugging in, check to see that the rated
mains voltage and mains frequency, as stated on
the rating label, match your power supply.
