Set-Up

Fuel Recommendations

Use automotive gasoline (unleaded or low leaded to minimize combustion chamber deposits) with a minimum of 87 octane. Gasoline with up to 10% ethanol (E10) or 15% MTBE (Methyl Tertiary Butyl Ether) can be used. Never use an oil/gasoline mixture or dirty gasoline. Avoid getting dirt, dust, or water in the fuel tank. DO NOT use E15 or E85 gasoline.

  • Refuel in a well-ventilated area with the engine stopped. Do not smoke or allow flames or sparks in the area where the engine is refueled or where gasoline is stored.
  • Do not overfill the fuel tank. After refueling, make sure the tank cap is closed properly and securely.
  • Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine.
  • Avoid repeated or prolonged contact with skin or breathing of vapor.

Adding Fuel

  1. Remove the gas cap, check the fuel level and add fuel if necessary. Fill the tank until the fuel reaches 1/2” below the bottom of the filler neck to allow for fuel expansion. Be careful not to overfill.

Checking & Adding Oil

  1. Place the snow blower on a flat, level surface.
  2. On some models the oil filler cap/dipstick can be accessed on the left side of the shroud. See Figure 7. On other models the oil filler cap/dipstick can be accessed at the rear of the snow blower. See Figure 8.
  3. Remove the oil filler cap/dipstick and wipe the dipstick clean.
  4. Insert the oil filler cap/dipstick into the oil filler neck, but do not screw it in.
  5. Remove the oil filler cap/dipstick. If the level is low, slowly add oil until oil level registers between the upper lever and lower level. NOTE: Do not overfill. Overfilling with oil may cause smoking, hard starting, or spark plug fouling.
  6. Replace and tighten oil filler cap/dipstick firmly before starting engine.

NOTE: DO NOT allow oil level to fall below the lover level on the dipstick. Doing so may result in equipment malfunctions or damage.

NOTE: To change the oil on your engine, see the Maintenance section of this manual.

OPERATION

Now that you have set up your snow blower, it’s important to become acquainted with its controls and features. Refer to Figure 1.

NOTE: This Operator’s Manual covers several models. Features may vary by model. Not all features in this manual are applicable to all models and the unit depicted may differ from yours.

  7. Grasp the recoil starter handle and slowly pull the rope out. At the point where it becomes slightly harder to pull the rope, slowly allow the rope to recoil.
  8. Pull the starter handle with a firm, rapid stroke. Do not release the handle and allow it to snap back. Keep a firm hold on the starter handle and allow it to slowly recoil.
  9. Allow the engine to warm up several minutes, adjusting choke toward RUN position. Wait until engine runs smoothly before each choke adjustment.

Electric Starter (If equipped)

Determine that your home’s wiring is a three-wire grounded system. Ask a licensed electrician if you are not certain.

If you have a grounded three-prong receptacle, proceed as follows:

  1. Make certain the auger control is in the disengaged (released) position.
  2. Insert ignition key into slot. Make sure it snaps into place. Do not attempt to turn the key. See Figure 3 for models CMXGBAM1054540 and CMGSB21179. NOTE: The engine cannot start unless the key is fully inserted into the ignition switch.
  3. Plug the extension cord into the outlet located on the engine’s surface. Plug the other end of extension cord into a three-prong 120-volt, grounded, AC outlet in a well-ventilated area See Figure 4.
  4. Push the choke lever to the CHOKE position.
  5. If the engine is warm, place the choke in the RUN position instead of CHOKE.
  6. Push the primer three (3) times for models CMXGBAM1054540 and CMGSB21179, making sure to cover the vent hole when pushing.
  7. If the engine is warm, push the primer button only once.
  8. Push starter button to start engine.
  9. Once the engine starts, release starter button.
  10. Allow the engine to warm up several minutes, adjusting choke toward RUN position. Wait until engine runs smoothly before each choke adjustment.
  11. When disconnecting the extension cord, always unplug the end at the three-prong wall outlet before unplugging the opposite end from the snow blower.

Stopping the Engine

  1. Run the engine for a few minutes without engaging the auger before stopping to help dry off any moisture on the engine.
  2. To stop the engine remove the key and store it in a safe place. NOTE: Remove the key to quickly stop the engine in the event of an emergency
  3. Wipe all the snow and moisture away from the engine controls area

Engaging the Auger

  • Engage the auger by squeezing the auger control against the upper handle. Release the control to stop the auger.

Engaging the Drive

  • Lift up slightly on the upper handle to allow the rubber paddles on the auger to contact the pavement and propel the snow blower forward. Pushing downward on the handle will raise the auger off the ground and stop the forward motion.

NOTE: Excessive upward pressure on the handle will result in premature wear to the rubber auger paddles.

Clearing a Clogged Discharge Chute

Hand contact with the rotating impeller inside the discharge chute is the most common cause of injury associated with snow blowers. Never use your hand to clean out the discharge chute. To clear the chute:

  1. Stop the engine. See instructions above for how to stop the engine.
  2. Wait 10 seconds to be sure the impeller blades have stopped rotating.
  3. Always use a clean-out tool or stick, not your hands.

Operating the Snow Blower

  • Once the auger drive is engaged, roll the snow blower into the layer of snow to be removed.
  • Adjust the chute so that the snow is not thrown over other snow that is to be removed.
  • Prevent possible property damage or personal injury from object ricochet by planning your snow throwing pattern to avoid discharge towards windows, walls, cars, etc.
  • Do not overload machine capacity by attempting to clear snow at too fast of a rate.
  • Never operate this machine without good visibility or light.
  • Always be sure of your footing and keep a firm hold on the handles.
  • Walk, never run when operating snow blower.
  • Look down and behind and use care when backing up.

SERVICE AND MAINTENANCE

MAINTENANCE SCHEDULE

Follow the maintenance schedule given below. This chart describes service guidelines only. Use the Service Log column to keep track of completed maintenance tasks. To locate the nearest authorized Service Center or to schedule service, call the following toll free number: 1-888-331-4569.

NOTE: This Operator’s Manual covers several models. Snow blower features may vary by model. Not all features in this manual are applicable to all snow blower models and the snow blower depicted may differ from yours.

Maintenance

Engine

  • Refer to the Engine Operator’s Manual for all engine maintenance procedures. Checking, adding and changing oil are also found in this manual.

Lubrication

  • Lubricate the pivot points on the control handle and the extension spring at the end of the control cable with a light oil once every season and before the snow blower is put into storage at the end of the season.

Adjustments

Shave Plate

To check the adjustment of the shave plate, place the machine on a level surface. The wheels, shave plate and auger paddles should all contact the level surface. Note that if the shave plate is adjusted too high, snow may blow under the auger housing. If the shave plate wears out excessively, or the snow blower does not selfpropel, the shave plate may be too low to the ground and needs to be adjusted.

NOTE: On new snow blowers or machines with a new shave plate installed, the auger paddles may be slightly off the ground.

To adjust the shave plate proceed as follows:

  1. Run the snow blower until the fuel tank is empty.
  2. Pull the starter cord until resistance is felt. Then tip the snow blower back until it rests on the handles. To ensure that the snow blower does not tip forward, it may be necessary to secure the handle to the ground with a block or other object.
  3. Loosen the four flange lock nuts and carriage screws which secure the shave plate to the housing. See Figure 1. Move the shave plate to the appropriate position and retighten the nuts and screws securely.
  4. Tip the snow blower back to the operating position and pull the recoil starter handle a few times to see if it is difficult to pull.
  5. If the starter is difficult to pull, remove the spark plug and pull the handle several times to ensure that any oil trapped in the engine head is removed.
  6. Inspect the spark plug. If it is wet, clean off any oil before re-installing.

Control Cable

As a result of both the control cable and the auger drive belt stretching due to wear, periodic adjustments may be necessary. If the auger seems to hesitate when rotating, proceed as follows:

  1. The upper hole in the control handle provides for an adjustment in cable tension. To adjust, disconnect the end of control cable from the bottom hole in the control handle and reinsert it in the upper hole. Insert the cable from the outside as shown in Figure 2.
  2. Test the snow blower to see if there is a noticeable difference. If after the adjustment to the control cable the auger still hesitates when rotating, see Auger Drive Belt Replacement for instructions on replacing the belt.

Chute Assembly

  • Refer to the Assembly section for instructions on adjusting the chute assembly.

Service

Auger Drive Belt Replacement

  1. Run the snow blower until the fuel tank is empty.
  2. Pull the recoil starter handle until resistance is felt. Then tip the snow blower back until it rests on the handles.
  3. Slide a board up through the auger and through the chute to secure the auger in place.
  4. Remove the belt cover by removing the two hex washer screws and one hex lock screw that secure it to the frame. See Figure 3.
  5. Remove the flange nut that secures the auger pulley to the auger shaft. See Figure 4.
  6. Remove the auger pulley and the belt.

To replace the belt follow these instructions and refer to Figure 5:
