Adjustments
〈Adjusting the main clutch〉
1. Turn the installation knob on the front cover in the
counterclockwise direction to loosen it, and open the
cover by lifting it upwards with your hands.
2. Use a spanner to loosen the two clutch wire locknuts
by turning them in opposite directions.
3. Make adjustments so that the spring on the back of the
handle stretches 4 to 5mm when the clutch lever is
moved in the “Run” direction.
4. After adjustments are complete, tighten the two lock-
nuts by turning them in the directions opposite to step
2 to fix the length of the wires.
5. Close the front cover, and turn the installation knob on
the front cover in the clockwise direction until it stops
to fix the front cover.
●
After making these adjustments, follow the procedure under
“Checking the operation of the main clutch” on page 17 to
check the operation of the main clutch.
●
With the main clutch in the “Stop” position and the shift
knob in the “H” or “L” position, pull the recoil starter. If the
mower does not move, the main clutch is not engaged.
6. The clutch wire can also be adjusted at the clutch wire
installation fitting position on the back of the handle. If
adjustments in inside the front cover are insufficient, try
making similar adjustments in this location.
