Adjusting The Chain - Ryobi OPP1850 Original Instructions Manual

MAINTENANCE

ADJUSTING THE CHAIN

1. Turn off the product and then remove the
battery pack.
2. Using the allen key wrench, loosen the bar
bolt of the drive case.
3. 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
until sag does not exist.
NOTE: Hold the tip of the bar up and tighten
the bar bolt securely. The chain tension is
correct when the gap is about 3-4 mm. Since
the chain will stretch when it heats up, then it
is recommended that the chain tension must
be checked regularly in use.
NOTE: If the chain is too tight, it will
not rotate. Loosen the bar bolt slightly
and turn chain tensioning screw 1/4 turn
counterclockwise. Lift the tip of the bar up
and re-tighten bar bolt
4. Fully tighten the bar bolt and drivecase cover.
Bar bolt should have at least 4 turns after
finger tight.
