Make sure all safety guards are in place and all nuts, bolts, clips, cotter pins and wires are secure. 2. Check to make sure spark plug wire is attached. 3. Check all controls for proper operation: a. The engine should stop when the key is removed. b. The fuel shut-off valve should stop the flow of fuel to the engine c. The recoil starter or electric starter (if equipped) should crank the engine when activated. 4. Check the engine area for oil or gasoline leaks. Correct any problems in accordance with the engine manufacturers instructions. 5. Check to make sure that the on/off switch is set to the ON position. Check Snowthrower Controls 1. Check the skid shoes to make sure they are set at the desired height. Adjust if necessary. 2. Check the traction drive control (A, Figure 18). Snowthrower motion should stop when the control is released. 3. Check the auger control (C). Auger movement should stop when the control is released. 4. Check the chute direction control (D) for proper operation. The discharge chute should rotate freely in both directions. 6. Check the speed selector (B) for smooth operation. The control must move freely into each speed position gate and remain in position when released. If controls do not function properly, perform the appropriate adjustment as shown in the Adjustment Section. 6. The auger is secured to the shaft by shear pins, which will break if the auger strikes an object. Extra shear pins are provided. Keep these pins with the Operators Manual. Lubricate the auger shaft.

Auger should come to a complete stop within five seconds each time. If not, perform Auger Adjustments. 3. Engage traction control and release. Do this ten times. Unit should come to a complete stop each time. If it does not, perform the Traction Drive Adjustments. 4. Remove the engine key. The engine must stop. 6/2006 9 TP 300-5196-00-IS-SN Intermediate Frame Snowthrowers TP 300-5196-00-IS-SN 10 6/2006 Auger Drive Linkage Adjustment Adjustments Figure 19. Auger Drive Adjustment A. Adjusting Flats D. Nut B. Spring Hook E. Adjustment Screw C. Lever A C D E B 1. With the drive lever released, the hook (B, Figure 19) should barely touch the lever (C) without raising it. There can be a maximum 1/32” clearance as shown. 2. To adjust, loosen nut (D, Figure 19) by holding the adjusting flats (A)and turning nut (D). Turn adjustment flats and hold screw. The adjustment screw is a phillips screw and the head can be held or turned by inserting a screwdriver through the spring. 3. Hold adjusting flats (A) and tighten nut (D). 4. Start unit and check auger. Auger must not be engaged unless auger control is depressed. 5. With engine running, fully depress auger control, the auger should engage and run normally. 6. Release auger control. Auger must stop within 5 seconds. Traction Drive Linkage Adjustment 1. With the drive lever released there should be no slack in the cable when moved slightly from side to side, but bellcrank arm (C, Figure 20) remains in fully down position. 2. To adjust tension on the cable loosen adjustment hex nut (D) by holding the adjusting flats (A). Turn the adjustment screw. The adjustment screw is a phillips screw and the head can be held or turned by inserting a screwdriver through the traction drive clutch cable spring 3. Engage the drive lever to check the adjustment. When correct, tighten hex nut securely. The unit should able to be pushed forward and back freely. Run-In Adjustment 1. After 5 hours of use, check for proper adjustment. Readjust clutch cable if necessary by increasing tension on cable. A small amount of bellcrank arm movement is permissible if unit passes operating checks described in the Caution at right. Figure 20. Traction Drive Adjustment A. Adjusting Flats D. Nut B. Spring Hook E. Adjustment Screw C. Bellcrank Arm D E B C WARNING Do not over-tighten, as this may cause traction drive to engage without depressing the traction drive control (bellcrank arm must remain in down position). Verify that the cables are not over-tightened: With speed selector in position 1 and traction drive control fully released, push snowthrower forward. The unit should move forward freely. If unit does not move forward freely, the cable has been over-tightened. To remedy, loosen tension on clutch cable slightly, and recheck. Intermediate Frame Snowthrowers Speed Selector Adjustment 1. Loosen the two nuts (A, Figure 21). 2. Place the shift lever (B, Figure 18) in 5th gear. The lower speed selector rod (B, Figure 21) will properly locate itse...
