ADJUSTING THE CHAIN TENSION
Loosen the guide bar locking knob slightly by
turning it counterclockwise.
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.
The chain tension is correct when the gap between
the cutter in the chain and the bar is between
3-4mm. 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, Fig.5.
Tighten the guide bar locking knob by turning it
clockwise.
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.
CHAIN LUBRICANT
•
Proper lubrication of the chain while in
operation reduces the friction between the
chain and the guide bar and assures a longer
tool life. Use only special chain oil of a high
quality for this purpose.
•
Do not use any waste or reclaimed oil as this
could cause various problems with the oil
pump.
SAW CHAIN / BAR LUBRICATION
Adequate lubrication of the saw chain is essential
at all times to minimize friction with the guide bar.
Never starve the bar and chain of oil. Running the
saw with too little oil will decrease cutting efficiency,
shorten saw chain life, cause rapid dulling of chain,
and cause excessive wear of bar from overheating.
Too little oil is evidenced by smoke, bar
discolouration or pitch build-up. New chains/bars
should be lubricated by hand before starting.
ASSEMBLY
ADDING CHAIN LUBRICATING OIL
Clear surface around the oil cap to prevent
contamination.
Unscrew and remove the cap from the oil tank,
Fig.6.
Pour oil into the oil tank and monitor the oil level
gauge. Ensure that no dirt enters the oil tank while
filling. The manufacturer recommends you use only
Ryobi chainsaw lubricating oil. (Available from your
authorised Ryobi service centre)
Put the oil cap back on and tighten it up. Wipe
away any spillage.
One full oil tank will enable you to use the saw for
20-40 minutes.
