ADJUSTMENT OF CHAIN OIL SUPPLY
The chain oil quantity discharged through the lubrication system is
factory-adjusted to the standard. Adjust the quantity in accordance
with the operating condition. The numbered label (26) describes
order of chain oil adjustment. ( Fig. 15 )
○
Loosen the fi xing screw (27) one turn. ( Fig. 15 )
○
Turn the adjusting screw (28) clockwise to decrease the quantity
and turn it counter-clockwise to increase the quantity. ( Fig. 16 )
○
Do not try to turn the screw (28) clockwise beyond 1 turn from
its most counter-clockwise position or the maximum quantity
discharged position.
○
After adjustment has been made, tighten fi xing screw (27).
( Fig. 15 )
NOTE
When you have lost the proper position of the screw (28), start
with the most counterclockwise position.
