ADJUSTMENTS/ MAINTENANCE
CHUTE CRANK ADJUSTMENT ~ FIGURE 6
In the event the chute crank fails to rotate smoothly, loosen the
nut securing the worm clevis to the bracket. This hoie in the
bracket is slotted to permit adjustment. Position the worm so
there is a little clearance between worm and the gear teeth on the
blower. Tighten the nut. Rotate the discharge chute through its
full travel to see that it turns easily. Readjust if required.
Lubricate as described in “LUBRICATION” section for smooth
operation.
TRACTION CLUTCH ADJUSTMENT - FIG. 5, 7 & 13B
The only adjustment for the drive disc is made by adjusting the
length of the traction clutch rod. Loosen setscrew in the rod
adapter and allow clutch lever to lay down on handle grip. Shift
Speed Selector to third gear. Raise rod adapter bracket until it
clears the top of the slot in frame by 1/16“ and tighten
setscrew. See Figure 13B
Check for proper adjustment by removing the bottom cover and
measuring the space between the roll pin and bracket on the
traction rod. This space must be 1/8 - 3/16“ with clutch lever
engaged, for proper operation. See Figure 7.
