Mounting flange 5. Check operation. Move gear slightly outward if binding is evident. CHECK TIRE PRESSURE IMPORTANT: Check pressure of tires because they are over-inflated at the factory for shipping. Therefore, before the snowblower is operated, reduce pressure in both tires to 7-15 psi equally. INSTALL SKIDS 1.
ASSEMBLY INSTRUCTIONS CHECK AUGER GEAR BOX OIL {Fig. 10) 1. Move snow thrower to a level surface. 2. Clean ares around pipe plug so dirt is removed, 3. Remove pipe plug from gear box. 4. Check oil revel in gear box. Oil must be at point of overflowing in filler opening. 5. If Tevet of oil is low, add LG-5 or LG-8 SAE 8595 EP transmission oil to the gear box until point of overflow. Note: Do not use synthetic gear oil. 8. Reinstall pips plug in gear box. Figure 10 1.
BEFORE OPERATING A\ WARNING DANGER: Because gasoline is flammable, caution must be used when storing or handling it. Do not flit fuel tank while engine is running, hot, or when unit is in an enclosed area. Keep away from open flame and electrical spark. DO NOT SMOKE while filling the fuel tank to prevent the possibility of an explosion. At ways fill fuel tank outside and wipe up any spilled gasoline before starting engine. Use a funnel or spout to prevent spilling gasoline. Do not il tank fool.

OPERATING INSTRUCTIONS POWER SHIFT OPERATION Wheels will shift forward {or rearward) with every other movement of the shift control. Move wheels to the rear Prows Shift position in heavy and/or drifted snow. Leave wheels in the front position for light snow or for transporting snow thrower. 1. Release traction drive lever, 2. To move wheels to front or rear position, move shift control fully forward to Power Shift position and hood (Fig. 18}, 3.
OPERATING INSTRUCTIONS 9. Move wheels to the rear Prows Shift position and shift to a lower gear in heavy and for drifted snow to prevent the auger housing from riding up over the snow. 10, Always use full throttle {(maximum engine speed) when throwing snow. 11, In wet or slushy conditions, clogging of the discharge chute will be reduced by maintaining maximum engine speed and by not overloading the engine.
OPERATING INSTRUCTIONS 3. Check scraper adjustment to ensure that the auger does not contact the pavement; refer to Adjusting Scraper, page 15. 4. Move the wheels 10 the REAR Power Shift position. 5. Support the scraper 1o be 1/8 inch above a revel surface if the snow thrower is 10 be used on Smooth pavement. Note: The scraper should be higher than 3/16 inch above'the pavement if the pavement surfaces are cracked, rough or uneven. 8.
MAINTENANCE LUBRICATING SNOW THROWER 1. Annually lubricate drive chain with chain lubricant (Fig. 25). Wipe up any excess oil. Figure 25 1. Drive chain CHANGING CRANKCASE Ol (Fig. 26) initialism, change oil after the first 2 hours of engine operation; thereafter, change oil alter every 25 hoers of engine operation or annually. i possible, run engine just before changing oil because warm oil flows better and carries more contaminants than cold oil, 1.
MAINTENANCE Figure 28 3. Flange head cap screw (3) 1. Upper belt caver 2. Calve cover 3. Depress the augerfimpeiler control lever on the right hand grip. Hold the lever and insert a .010" (.25 mm) feeler gauge between a coil in the center of the spring (Fig. 29). Adjust the cable to achieves .010” (.25 mm) gap between the coils. Figure 29 1. Falser gauge 2. Center of spring 4. Loosen upper jam nut securing auger/impeller cable to mounting bracket (Fig. 30). 18 Figure 30 1.
MAINTENANCE 10. Check tension of belt by operating the auger. It belt still slips, replace the belt. T 1/8 Min, = P 1. Impeller idler arm 2. Brake arm ADJUSTING TRACTION DRIVE BELT (Fig. 30) If the wheels do not turn when the traction lever is depressed, the traction belt tension should be increased. Whenever the bat is replaced, an adjustment is required. 1. Loosen upper jam nut securing traction cable 10 mounting bracket, 2. Rotate bottom jam nut upward 1o increases bat tension.
MAINTENANCE A ‘DANGER ® IMPROPER ADJUSTMENT MAY CAUSE INJURY IF AUGER/IMPELLER TURNS WHEN DISENGAGED, & ROTATION AUGER CAN Fl ERS QR HANDS. « KEEP FACE, HANDS, FEET AND ANY OTHER PART OF YOUR BODY OR CLOTHING AWAY FROM CONCEALED, MOVING OR ROTATING PARTS. « MAKE CERTAIN THAT IMPELLER BRAKE ARM CLEARANCE 1S MAINTAINED. ¢ DO NOT ADJUST THE AUGER/IMPELLER DRIVE BELT TOO TIGHT BECAUSE IT MAY CAUSE THE AUGER/IMPELLER TO TURN WHEN THE CONTROL LEVER IS IN THE DISENGAGED POSITION.
MAINTENANCE B. Rotate bait joint up or down until gear shift lever is aligned with Power Shift soot. €. Reinstall ball joint to transmission lever and tighten jam nut. Figure 36 8. Lockout 6.

Remove carburetor heater box: see To Start Engine, paragraph one, steps A & B, page 13.
MAINTENANCE 7. Rotate die mixture screw clockwise—in—1/8 turn at a time until engine begins to miss because of a lean mixture. Then rotate screw counterclockwise—out—1/8 turn at a time until engine runs unevenly because of rich mixture. Next, rotate ids mixture screw clockwise, back to the mid-point between rich and lean settings. Note: Wait several seconds between each 1/8 turn setting so engine can adjust to the new fuel remix. 8. Again, rotate idle speed screw until engine idles at 1780 rpm, 9.
