SAFETY DECALS AND LOCATIONS WARNING: POTENTIALLY HAZARDOUS SITUATION! If not avoided, COULD RESULT in death or serious injury. ALWAYS replace missing or damaged Safety Decals. Refer to figures below for Safety Decal locations. 1 CAUTION: POTENTIALLY HAZARDOUS SITUATION! If not avoided, MAY RESULT in minor or moderate injury. It may also be used to alert against unsafe practices. 2 08000134 NOTATIONS 3 NOTE: General reference information for proper operation and maintenance practices.
Wear appropriate hearing protection. OL4690 ONLY use clean-out tool to clear blockages. NEVER use your hands. 2. DANGER! OS6610 ROTATING PARTS! ONLY use clean-out tool to clear blockages. NEVER use your hands. High speed impeller rotates below discharge opening. Wait for all moving parts to stop before removing clogs or servicing. 3. DANGER! OS2080 ROTATING PARTS. Keep clear of auger while engine is running. • Read Operator’s Manual. • Allow operation only by properly trained adult, never children.
ALWAYS keep hands away from all pinch points. DO NOT touch unit parts which might be hot from operation. Allow parts to cool before attempting to maintain, adjust or service. Never direct discharge towards persons or property that may be injured or damaged by thrown objects. Use extreme caution on gravel surfaces. Stay alert for hidden hazards or traffic. Adjust Runners so Scraper Blade does not contact gravel. DO NOT throw snow any higher than necessary.
Fuel is highly flammable and its vapors are explosive. Handle with care. Use an approved fuel container. NO smoking, NO sparks, NO flames. ALWAYS allow engine to cool before servicing. NEVER fill fuel tank when engine is running or hot from operation. NEVER fill or drain fuel tank indoors. Replace fuel cap securely and clean up spilled fuel. Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.
ASSEMBLY 5. Install and tighten all wing knobs and wing nuts on the handlebar assembly and shift rod. NOTE: The handlebar has two height positions. Adjust the handlebar height to provide better operator comfort. See Handlebar Height on page 27. WARNING: AVOID INJURY. Read and understand the entire Safety section before proceeding. WARNING: Dropping or tipping over boxed unit could result in personal injury or damage to unit. 5 PACKAGE CONTENTS 1 1 4 4 1, 3 2, 3 3 OS7030 1. Wing Knobs 2. Wing Nut 3.
NOTE: After the chute rod has been inserted through the hex hole in the control assembly, placing the unit in the service position (see Service Position on page 23) will ease alignment and installation of the hair pin. 8. Secure the chute rod to the control assembly with the hair pin removed in step 6 using the end hole location as shown in Figure 7. Insert the hair pin with the loop end to the left of the chute rod so the control assembly follows a full range of travel.
NOTE: Press down on lock teeth with your finger to align the cable ball end with the slot (Figure 8). 2 3 1 3 5 4 1. 2. 3. 4. 5. OS7271 Figure 8 10. Replace the gear cover removed in step 4. IMPORTANT: Rotate the discharge chute to the left when tightening the pedestal hardware to ensure clearance between the discharge chute and the belt cover. 11. Tighten pedestal hardware to 15 – 31 lbf-ft (20 – 42 N•m). 12.
CAUTION: Avoid injury! Explosive separation of tire and rim parts is possible when they are serviced incorrectly: • Do not attempt to mount a tire without the proper equipment and experience to perform the job. • Do not inflate the tires above the recommended pressure. • Do not weld or heat a wheel and tire assembly. Heat can cause an increase in air pressure resulting in an explosion. Welding can structurally weaken or deform the wheel. • Do not stand in front or over the tire assembly when inflating.

Squeeze Attachment Clutch Lever against handlebar (1) to engage attachment. Release both clutch levers (2) to disengage power and apply brake to attachment. 2 WARNING: To avoid injury to hands and feet, always disengage clutches, shut off engine, and wait for all movement to stop before unclogging or working on snow thrower.
Snow Clean-Out Tool Forward: (6) Fastest (1) Slowest Reverse: (1) Slow (2) Fast 6 (Figure 12) WARNING: Hand contact with the rotating impeller is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute. IMPORTANT: DO NOT change motion from forward to reverse with clutch engaged. Forward speed can be changed without declutching. 1 1 2 1 OS1196 Choke Control Knob 1 2 1.Choke Closed position: chokes off air to engine for easier start. 2.
Discharge Chute Control Differential Lock (926314, 315, 316) IMPORTANT: If chute does not stay in set position, adjust as directed in SERVICE AND ADJUSTMENTS on page 26, or repair before operation. Rotate the Chute with Discharge Chute Control. (Figure 14) The differential can be locked for maximum traction or unlocked to allow for easier turning. The differential lock knob is located on the right Track Assembly. With the differential locked power is applied equally to both tracks.
Scraper Blade The scraper blade allows the back of the housing to keep better contact with the surface being cleared. It also prevents damage to the housing from normal wear. 1 IMPORTANT: DO NOT allow Scraper Blade to wear too far or Auger/Impeller housing will become damaged. Runners The runners control the distance between the scraper blade and the ground. Adjust runners equally to keep blade level with the ground. Refer to Pre-Start on page 20 for recommended settings.
The fuel shut-off valve has two positions: Normal Closed Position: Use this position to service, transport, or store the unit. Transport Deep Cutting OS7117 Open Position: Use this position to run the unit. Figure 17 To add fuel to fuel tank: Figure 16 OS7111 FILLING FUEL TANK WARNING: AVOID INJURY.
