Chain Oiler; Chain Maintenance - Ryobi RPP680 Manual De Utilización

The bar contains a bar stud slot that fits over the bar
stud. The bar also contains a chain tensioning pin
hole which fits over the chain tensioning pin.
Place the bar onto the bar stud so that the chain
tensioning pin fits into the chain tensioning pin hole.
Fit the chain over the sprocket and into the bar
groove. The cutters on the top of the bar should
face toward the bar tip, in the direction of the chain
rotation.
Replace the drivecase cover and install the bar nut.
Tighten the bar nut finger tight only. The bar must be
free to move for tension adjustment.
Remove all slack from chain by turning the chain
tensioning screw clockwise, assuring that the chain
seats into the bar groove during tensioning.
Lift the tip of the bar up to check for sag. Release the
tip of the bar, and turn the chain tensioning screw 1/2
turn clockwise. Repeat this process until sag does not
exist.
securely.
on the underside of the bar, the chain is snug, but it
can be turned by hand without binding.
NOTE: If chain is too tight, it will not rotate. Loosen
the bar nut slightly and turn adjusting screw 1/4
turn counterclockwise. Lift the tip of the bar up and
retighten bar nut.
MAINTENANCE

CHAIN OILER

See Figure 16
for chains and chain oilers and is formulated to
perform over a wide temperature range with no
dilution required.
Remove the cap and carefully pour approximately
60 ml of bar and chain lubricant into the bar lube
reservoir.
Replace the cap and tighten securely.

CHAIN MAINTENANCE

See Figure 17.
English (Original instructions)
For smooth and fast cutting, the chain needs to be
maintained properly. The following conditions indicate
that the chain requires sharpening:
During maintenance of the chain, consider the following:
HOW TO SHARPEN THE CUTERS
See Figures 18 - 21.
Be careful to file all cutters to the specified angles and
to the same length, as fast cutting can be obtained only
when all cutters are uniform.

Wood chips are small and powdery.
cutting.
Improper filing angle of the side plate can increase
the risk of a severe kickback.
the height the cutter enters the wood and the size of
the wood chip that is removed. Too much clearance
increases the potential for kickback. Too little
clearance decreases the size of the wood chip thus
decreasing the chain's cutting ability.
If cutter teeth have hit hard objects such as nails and
stones, or have been abraded by mud or sand on the
wood, have service dealer sharpen chain.
Tighten the chain tension enough that the chain does
not wobble. Do all of your filing at the mid-point of the
bar. Wear gloves for protection.
Use a 5/32 in. diameter round file and holder.
Keep the file level with the top plate of the tooth. Do not
let the file dip or rock.
Using light but firm pressure, stroke towards the front
corner of the tooth. Lift file away from the steel on each
return stroke.
Put a few firm strokes on every tooth. File all left hand
cutters in one direction. Then move to the other side
and file the right hand cutters in the opposite direction.
Occasionally remove filings from the file with a wire
brush.
CAUTION:
Dull or improperly sharpened chain can cause
excessive motor speed during cutting which may
result in severe motor damage.
WARNING:
Improper chain sharpening increases the potential
of kickback. Failure to replace or repair damaged
chain can cause serious injury.
