ADJUSTING THE CHAIN
1.
Turn off the product and then remove the
battery pack.
NOTE: The product will be hot after use.
Allow the product to cool down before
adjusting the chain.
2. Using the allen key wrench, loosen the bar
bolt off 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, resulting in damage. 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 drive case
cover. Bar bolt should have at least 4 turns
after bringing to finger tight.
