2. Release the recoil starter handle and let it snap back against the starter.
   If the engine still fails to start, repeat the above steps or use the electric starter.

SNOW THROWING TIPS

• Always operate the snow thrower with the engine at full throttle. Full throttle offers the best performance.
• Go slower in deep, freezing or heavy wet snow. Use the drive speed control, NOT the throttle, to adjust speed.
• It is easier and more efficient to remove snow immediate ly after it falls.
• The best time to remove snow is the early morning. At this time the snow is usually dry and has not been exposed to the direct sun and warming temperatures.
• Slightly overlap each successive path to ensure all snow will be removed.
• Throw snow downwind whenever possible.
• Ad just the skid plates to proper height for current snow con di tions. See “TO ADJUST SKID PLATES” in this section of this manual.
• For extremely heavy snow, re duce the width of snow removal by over lap ping previous path and moving slowly.
• Keep engine clean and clear of snow during use. This will help air flow and extend engine life.
• After snow-throwing is completed, allow engine to run for a few minutes to melt snow and ice off the engine.
• Clean the entire snow thrower thoroughly after each use and wipe dry so it is ready for next use.

WARNING: Do not operate snow thrower if weather conditions impair visibility. Throwing snow dur ing a heavy, windy snowstorm can blind you and be hazardous to the safe operation of the snow thrower.

MAINTENANCE

GENERAL RECOMMENDATIONS

The warranty on this snow thrower does not cover items that have been subjected to operator abuse or negligence. To receive full value from the warranty, operator must maintain snow thrower as in structed in this manual. Some adjustments will need to be made periodically to properly  maintain your snow thrower.

All adjustments in the Service and Adjustments section of this manual should be checked at least once each season.

• Once a year, you should replace the spark plug and check belts for wear. A new spark plug will help your engine run better and last longer.
• Follow the maintenance schedule in this manual.

NOTE: Use only Original Equipment Manufacturer (OEM) parts to service this unit. Failure to do so can cause the unit to malfunction and pose a risk of injury to the operator.

BEFORE EACH USE

1. Check engine oil level.
2. Check for loose fasteners.
3. Check controls to be sure they are functioning properly.

LUBRICATION
Keep your snow thrower well lubricated (See “LU BRI CA TION CHART”). At the beginning of each season, or every 25 hours of use, apply a small amount of white lithium grease to the interlock bosses.

LUBRICATION CHART

➀ SAE 5W30 Motor Oil
➁ See “Engine” in Maintenance section
➂ White Lithium Grease

SNOW THROWER

Always observe the safety rules when performing any main te nance.

TIRES

• Maintain proper air pressure in both tires (14–17 PSI).
• Keep tires free of gasoline and oil, which can harm rubber.

NOTE: To seal tire punctures and prevent flat tires due to slow leaks, tire sealant may be purchased from your local parts dealer. Tire sealant also prevents tire dry rot and corrosion.

BELTS
Check belts for deterioration and wear after every 50 hours of operation and replace if necessary. The belts are not ad just able. Replace belts if they begin to slip from wear. (See “TO REMOVE BELT COVER” in the Service and Adjustments section of this manual).

The belts on your snow thrower are of special construction
and should be replaced by original equipment manufacturer (OEM) belts avail able from your nearest dealer. Using other than OEM belts can cause personal injury or damage to the snow thrower.

AUGER GEAR CASE

• The gear case was filled with lubricant to the proper level at the factory. The only time the lubricant needs attention is if service has been performed on the gear case.
• If lubricant is required, use only Ronex ED #1 grease.

TRACTION DRIVE SYSTEM
DO NOT lubricate the drive components inside the snow thrower. The sprockets, hex shafts, drive disc and friction wheel require no lubrication. The bearings and bushings are lifetime lubricated and require no maintenance.

CAUTION: Any lubricating of the above com ponents can cause contamination of the friction wheel and damage to the drive system of your snow thrower.

ENGINE
See engine manual.

LUBRICATION
Use only high quality detergent oil rated with API service classification SJ–SN. Select the oil’s SAE viscosity grade according to your expected operating temperature.

NOTE: Although multi-viscosity oils (5W30, 10W30 etc.) improve starting in cold weather, these multi-viscosity oils will result in increased oil consumption when used above 32°F. Check your engine oil level more frequently to avoid possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at least once a year if the snow thrower is not used for 25 hours in one year. Check the crankcase oil level before starting the engine and after each five (5) hours of continuous use. Tighten oil fill cap / dipstick securely each time you check the oil level.

TO CHANGE ENGINE OIL

Determine temperature range anticipated before next oil change. All oil must meet API service classification SJ–SN.

• Be sure snow thrower is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.

NOTE: A wheel may be removed from snow thrower for easier access to the oil drain plug and placement of a suitable container.

1. Remove safety ignition key and disconnect spark plug wire from spark plug. Place wire where it cannot come in contact with spark plug.
2.  Clean area around drain plug.
3.  Remove drain plug and drain oil in a suitable container.
4.  Install drain plug and tighten securely.
5.  Wipe off any spilled oil from snow thrower and engine.
6.  Install left wheel (if removed for draining oil). Be sure to install wheel pin and retainer pin into proper hole in wheel axle (See “TO REMOVE WHEELS” in the Service and Adjustments section of this manual).
7.  Remove oil fill cap/dipstick. Be careful not to allow dirt to enter the engine.
8. Refill engine with oil through oil dipstick tube. Pour slowly. Do not overfill. For approximate capacity see “PRODUCT SPECIFICATIONS” section of this man u al.
9.  Use gauge on oil fill cap/dipstick for checking level. Be sure dipstick cap is tightened securely for accurate reading. Keep oil at “FULL” line on dipstick.
10.  Wipe off any spilled oil.

ENGINE

SEE ENGINE MANUAL

CARBURETOR
Your carburetor is not adjustable. Engine performance should not be affected at altitudes up to 2,134 meters. If your engine does not operate properly due to suspected carburetor problems, take your snow thrower to a service center/department.

ENGINE SPEED
Never tamper with the engine governor, which is factory set for proper engine speed. Over speeding the engine above the factory high speed setting can be dangerous and will void the warranty. If you think the engine-governed high speed needs adjusting, contact a service center/department, which has the proper equipment and experience to  make any necessary adjustments.

TO ADJUST CHUTE ROTATOR CABLE TENSION

(See Fig. 25)

1. Adjust cable tension by loosening the jam nuts next to the turn buckle.
2. Grasp the short section and hold while turning the long section to lengthen the adjuster.
3. Adjust until cable is snug and tighten jam nuts.

AUGER PERFORMANCE AND CABLE ADJUSTMENT

(See Fig. 25)

NOTE: If you do not feel comfortable making this adjustment yourself, please contact an authorized service center/ department.
Adjustments may be needed if the impeller and auger rotation is sluggish when engaging the auger control lever, or if the auger belt has been replaced.

To adjust the auger control cable:

1. Adjust cable tension by loosening the jam nut, next to the turn buckle.

2. Grasp the short section and hold, while turning the long section to lengthen the adjuster. Rotate the center barrel one full revolution.

3. Retest auger engagement. Repeat adjustment as needed until engagement is no longer sluggish.

4. Have an assistant stand 10 feet in front of the machine, and on the opposite side that the chute is pointing. The assistant should observe the rotation of the auger and measure the time it takes for the auger to stop rotating after you release the lever.
   If the auger stops rotating after 5 seconds, readjust the cable by rotating the center barrel one full revolution, so that the adjuster is contracting. Retest the auger engagement and measure the stop time again.
   If the auger stops rotating in less than 5 seconds, proceed to the next step.

5. Tighten the jam nut on the auger cable.
   NOTE: If the adjustment does not resolve the problem, replace the auger belt. See “To Replace Belts” in the Service & Adjustments section of this manual.

STORAGE

Immediately prepare your snow thrower for storage at the end of the season or if the unit will not be used for 30 days or more.

WARNING: Never store the snow thrower with gasoline in the tank in side a building where fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer or gas appliance. Allow the engine to cool be fore storing in any enclosure.

SNOW THROWER

When snow thrower is to be stored for a period of time, clean it thoroughly, re move all dirt, grease, leaves, etc. Store in a clean, dry area.

1. Clean entire snow thrower (See “CLEANING” in the Maintenance section of this manual).
2. Inspect and replace belts, if necessary (See “TO REPLACE BELTS” in the Service and Adjustments section of this manual).
3. Lubricate as shown in the Maintenance section of this man u al.
4. Be sure that all nuts, bolts, screws, and pins are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary.
5. Touch up all rusted or chipped paint surfaces; sand lightly before painting.

ENGINE
See engine manual.

FUEL SYS TEM
IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as carburetor, fuel hose, or tank during storage. Also, alcohol blended fuels (called gasohol or using ethanol or methanol) can attract moisture which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage.

• Empty the fuel tank by starting the engine and letting it run until the fuel lines and carburetor are empty.
• Never use engine or carburetor cleaner products in the fuel tank or permanent damage may occur.
• Use fresh fuel next season.

NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage. Add stabilizer to gasoline in fuel tank or storage container. Always follow the mix ratio found on stabilizer container. Run engine at least 10 minutes after adding stabilizer to allow the stabilizer to reach the carburetor. Do not drain the gas tank and carburetor if using fuel stabilizer.

ENGINE OIL
Drain oil (with engine warm) and replace with clean engine oil. (See “ENGINE” in the Maintenance section of this manual).

CYLINDER

1.  Remove spark plug.
2. Pour one ounce (29 ml) of oil through spark plug hole into cylinder.
3. Pull recoil starter handle slowly a few times to dis tribute oil.
4. Replace with new spark plug.

OTHER

• Remove safety ignition key; store it in a safe place.
• Do not store gasoline from one season to another.
• Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems.
• If possible, store your snow thrower indoors and cover it to protect it from dust and dirt.
• Cover your snow thrower with a suitable pro tec tive cover that does not retain moisture. Do not use plastic. Plastic cannot breathe, which allows condensation to form and will cause your snow thrower to rust.

IMPORTANT: Never cover snow thrower while engine/exhaust area is still warm.
