SPECIAL PRODUCT FEATURES
n
Special safety wrap-spring chain brake. In case of a
kickback or if the trigger is released, the chainsaw
comes to a standstill within 1/10 of a second.
n
Sawing chain with safety driving links to reduce the
risk of kickback.
n
Large chain brake near the front handle. In cases of
kickback the chain brake is pushed forward by the
back of the operator’s hand which trips the wrap-
spring chain brake.
n
Lock off switch to protect against unintentional start
of the chainsaw.
n
Live tool indicator to indicate a good connection with
power.
COMMISSIONING
Assembling the bar and chain
Remove the mains plug out of the socket.
Wear protective gloves.
n
Unscrew the sprocket cover adjust knob and remove
the sprocket cover. (Fig. 1)
n
The chain should face in the direction of chain
rotation. If they face backwards, turn the loop over.
(Fig. 4)
n
Place the chain drive links into the bar groove. (Fig.
5)
n
Position the chain so there is a loop at the back of
the bar.
n
Hold the chain in position on the bar and place
the loop around the sprocket and make sure it is
correctly mounted. (Fig. 6)
Note:
The chain is correctly tensioned if the cutter
can be lifted 3 to 4mm from the resting position.
n
Turn the chain tensioning bolt clockwise until the
chain is correctly tensioned. While the bolt is being
tightened, the bar must then be pushed upwards,
check chain tension again, do not tension the chain
too tightly. (Fig. 7)
n
Replace the sprocket cover on top and tighten gently
with the sprocket cover adjust knob.
Running in
Before cutting with a new chain, allow it to run freely
for 2~3 minutes.
WARNING:
After the run-in time, check the chain tension
and retighten the chain if necessary.
Chain lubricating oil
The chainsaws are delivered
without oil in the tank.
Prior to initial operation of the machine, the oil tank
must be filled with chain and bar oil.
Ryobi chainsaw adhesive oil is biologically degradable
and permits chainsaw operation at temperatures as low
as -15°C.
The oil tank cap is removed to fill the oil. When filling the
oil, ensure that no dirt gets into the oil tank. The oil level
can be monitored at the oil sight gauge. One filling of the
oil tank (capacity 0.2L) is sufficient for 25~40 minutes of
chainsaw operation.
Checking chain lubrication
To prevent excessive wear, the chain and bar must
be evenly lubricated during operation. Lubrication is
automatic. Never work without chain lubrication. If the
chain runs dry, the entire cutting apparatus will quickly
become severely damaged. It is therefore important to
check both chain and bar lubrication and the oil gauge
before every use. Never use the saw when the oil level is
below the "Minimum" mark.
n
Minimum - When only approx. 5 mm of oil is visible at
the lower rim of the oil gauge, you must top up with
oil.
n
Maximum - Top up with oil until the window is full.
WARNING:
Never work without chain and bar lubrication.
To check the automatic chain lubrication system is
working, hold the chain saw with the cutter (and chain
running) at a safe distance of about approx. 20cm over
a light colored base, e.g. a spread-out newspaper). If
increasingly large oil marks appear on the light colored
base, the chain lubrication is working correctly.
Chain Brake
The integrated chain brake brings the chain to a standstill
within 1/10 of a second if the chain brake is moved either:
-- Manually to its front position, or during work with the
back of the operator’s hand (due to kickback) , or if
-- The chainsaw is switched off by releasing the trigger.
If the quick brake of the chainsaw is tripped through
actuation of the Chain Brake near the front handle, do
not allow the chainsaw motor to run in this position for
unnecessarily long periods. Push the chain brake back to
its initial position.
WARNING:
Before operating the chainsaw, 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.
