bolt and hole align. You may rotate this assembly again
to apply some tension to the chain which will help keep
it in place.
7. Replace the sprocket cover and turn the chain tensioner
knob until nearly tight, turn the chain tension adjustment
ring until the saw chain is properly tensioned. The guide
bar must then be pushed upwards, check chain tension
again, do not tension the chain too tight.
8. After the chain is well-tensioned, tighten the knob again.
ADJUSTING THE CHAIN TENSION
See page 263. See page 273.
1. Loosen the chain tensioner knob slightly by turning it
counterclockwise.
2. To increase the chain tension, turn the chain tensioner
adjustment ring clockwise and check the chain tension
frequently. To reduce the chain tension, turn the chain
tensioner adjustment ring counterclockwise and check
the chain tension frequently.
3. The chain tension is correct when the gap between the
cutter in the chain and the bar is between 4 mm - 5.5
mm. Pull the chain in the middle of the lower side of the
bar downwards (away from the bar) and measure the
distance between the bar and the chain cutters.
4. Tighten the chain tensioner knob by turning it clockwise.
OPERATION
ADDING CHAIN LUBRICATING OIL
See page 262.
WARNING
Never work without chain lubricant. If the saw chain is
running without lubricant, guide bar and saw chain can
be damaged. It is therefore essential to check the oil
level in the oil level gauge frequently and every time
before starting to use the chain saw.
1. Clear surface around the oil cap to prevent
contamination.
2. Unscrew and remove the cap from the oil tank.
3. Pour the oil into the oil tank and monitor the oil level
gauge. Ensure that no dirt enters the oil tank while
filling.
4. Put the oil cap back on and tighten it up. Wipe away
any spillage.
5. One full oil tank will enable you to use the saw for 20-
40 min.
Recommended chain lubricating oil
■
The manufacturer recommends you use only Ryobi
chainsaw lubricating oil. (Available from your authorised
Ryobi service centre)
INSTALLING THE BATTERY PACK
See page 263.
1. Place the battery pack in the chainsaw. Align raised ribs
on battery pack with grooves in the chain saw's battery
port.
2. Make sure the latches on the battery pack snap in place
and that the battery pack is secured in the chainsaw
before beginning operation.
HOLDING THE CHAIN SAW
See page 263.
Always hold the chain saw with your right hand at the rear
handle and your left hand at the front handle. Grip both
handles with the thumbs and fi ngers encircling the handles.
Ensure that your left hand is holding the front handle so that
your thumb is underneath.
STARTING THE CHAIN SAW
See page 263.
1. Before starting for operation, you should install the
battery pack in the machine, and make sure chain
brake is in run position by pulling chain brake lever /
hand guard toward the front handle.
2. To start the product: pull the trigger release, and then
press the switch trigger.
CHECKING AND OPERATING CHAIN BRAKE
1. Engage the chain brake by rotating your left hand
around the front handle. Allow the back of your hand to
push the chain brake lever/hand guard toward the bar
while the chain is rotating rapidly. Be sure to maintain
both hands on the saw handles at all times.
2. Reset the chain brake back into the Run position by
grasping the top of the chain brake lever / hand guard
and pulling toward the front handle until you hear a
click.
WARNING
If the chain brake does not stop the chain immediately, or
if the chain brake will not stay in the run position without
assistance, take the saw to an authorised service centre
for repair prior to use.
