LINKAGE FOR THE HYDRAULIC CONTROLS

1. Selector lever. 2. Lever for direction control. 3. Rod. 4. Lever for speed control. 5. Rod.

1. Put lever (4) for speed control in the NEUTRAL (lever up) position.

2. Make an adjustment to rod (5) so selector lever (1) moves freely through the neutralopening in the shift guide.

3. Put selector lever (1) in the maximum FORWARD-NEUTRAL position in the shiftguide.

4. Put lever (2) for direction control in the FORWARD (lever up) position.

5. Make an adjustment to rod (3) to fit.

Do not make any adjustments to the linkage with the enginerunning.
