8.5.
Test the operation of the unit. Repeat the adjustment if necessary.
NOTE: Most comfortable operation will be obtained when the adjustment allows the lever to just make contact with the hand grip when sufficient traction is achieved.
8.6.
When adjusted properly, tighten the lower jam nut against the block.
9.1.
To adjust use a 1/2” wrench to make a small (1/4 turn) adjustment to the brake locknut until the correct measurement is achieved. It may be necessary to relieve spring tension when decreasing distance. Have an assistant engage the operator presence control while you adjust the
9.
WHEEL BRAKE ADJUSTMENT
This adjustment may be required it the unit does not hold on a hill with the operator presence control disengaged, or if the brake drags with the operator presence control engaged and the transmission is in neutral.
(The unit should roll freely in this position.)
NOTE: With the operator presence control released there should be a 3/8” to 5/16” gap between the back of the brake arm and the

TRANSMISSION NEUTRAL ADJUSTMENT
With the unit turned off and the shift lever in the neutral detent position you should be able to hold down the operator presence control and roll the unit easily forward and back. Check this from forward and reverse positions. If the unit is in gear you will need to perform a neutral adjustment.

10.3. Moved the shift arm back and forth as necessary into each detent until the transmission is in neutral.
NOTE: Moving the shift arm clockwise all the way to the left, and then one notch counterclockwise should put the transmission in neutral. With the operator presence control lever down you should be able to easily roll the unit.
10.4. With the transmission in neutral, rotate the shift link until the hooked end easily fits into the hole
at the bottom end of the shift rod. See Figure 32.
NOTE: The shift rod must be held in the neutral position while the shift link is adjusted.
10.5. Secure the shift link into the shift rod with the hairpin clip removed earlier.
10.6. Recheck the neutral position and readjust if necessary. Check from both the forward and reverse direction.

INSTALLATION OF WHEEL DRIVE BELT
GUARDS - UPDATE
NOTE: Current production units have additional belt guards installed at the factory. This update will cover older units without pulley belt guards.
•
•
On older units the long run of the wheel drive belt creates several issues.
The belt may come off one of the pulleys.
The belt may not fully disengage from the engine pulley, causing engine creep or hard shifting
