For maximum snow removal and discharge maintain high engine A. P. M. Operate the tractor at a slow ground speed for safe and efficient snow removal (Usually 1st gear at full throttle). A definite pattern of operating is required to thoroughly clean the snow area. This pattern will avoid a second removal of snow and avoid throwing snow in unwanted places. 5 ADJUSTING AND OPERATING LIFT ASSIST SPRING 1 2 3 4 -Spring anchor chain -Lift assist spring chain -Quick-attachable cotter -Lift assist spring anchor pin bracket The lift assist spring is hooked to the snow thrower from on the left side, at the rear of the thrower. The lift spring helps to carry the weight of the snow thrower and makes raising the machine into transport position easier. The amount of tension in the lift assist spring will cause the scraping action of the thrower and/or the effort required to raise the snow thrower to vary. When the snow thrower is used on rough or uneven surfaces, less scraping is desired and more lift spring tension is necessary. When the snow thrower hard snow, lift spring more tension scraping Using the anchor chain handle, pull on the chain to raise the quick-attachable cotter pin up off of the anchor bracket surface. Remove the quick-attachable cotter pin from the anchor chain, while holding onto the chain handle. Allow several chain links to pass downward through the hole in the anchor bracket to reduce spring tension or pull several chain links up through th~ hole in the anchor bracket to increase spring tension and replace quick-attachabl~ cotter pin through a chain link just above the anchor bracket surface. Check to see that the lift lever effort, to raise the snow thrower is as desired and/or the down pressure of the snow thrower is adequate for required scraping. Too little tension may cause the chain to whip excessively and to jump off of the sprocket. Slack in the drive chain, due to normal chain stretch can be removed by adjustment if it becomes excessive. To adjust follows: the chain tension, proceed as Place a straight edge along the drive chain across the jackshaft sprocket and rotor/collector sprocket. A deflection of 1/4 to 3/8-inch when hand pressure is applied to the drive chain indicates the tension is correct. -Straight edge 2 -Jackshaft sprocket 3 -Rotor/collector drive chain 4 -Rotor/collector sprocket Loosen the mounting nuts two or three complete turns. Turn the adjustment nuts in or out until the desired tension is obtained. NOTE: Both adjustment nuts must be turnedthe same number of turns to avoid misalignment of the sprocket with the drive chain. Retighten the mounting nuts to secure After adjusting the drive chain, check the long V-belt adjustment guide and adjust if necessary. Refer to instructions "LONG V-BELT". 11 1 ADJUSTINGAND OPERATING LONG V-BELT Correct belt setting Correct 7 -Idler 8 -Idler 9 -Belt belt setting pulley bolt head pulley adjustment guide All belts stretch Underside view of rotor/collector housing and pivot bracket channel operation. during the first few hours of 2 3 4 5 6 -Rotor/collector -Pivot bracket -Pivot bracket -Inner eyebolt -Outer eyebolt -Eyebolts housing channel channel nuts nuts nuts Check the long V-belt tension after the first 1/2 hour, then every hour thereafter during the first five hours of use.

To adjust for the correct as follows: belt setting, proceed To keep the rotor/collector housing in alignment with the lower mounting frame, turn the two outer eyebolt nuts (in equal amount of turns) in a clockwise direction until the idler pulley bolt head moves to the center "RUN" area of the belt adjustment guide. After adjusting the belt tension, eyebolt nuts should be retightened. [. . . ] ASSEMBLINGTHE SNOWTHROWER THE TRACTOR ON Continued Raise the front end of the upper mounting frame and align it with the holes in the tractorframe. Insert locating pins and secure with quick-attachable cotter pins. Install the short V-belt on the tractor engine main drive pulley. Check to see that the long and short V-belts are seated in the grooves of the snow thrower pulleys and aligned with the tractor pro (power take-off) clutch pulley and engine main drive pulley. Refer to the belt layout diagrams and instructions under the heading "V-BELT REPLACEMENT" in "ADJUSTING AND OPERATING". 24 SETTINGUP 4.
