Always be aware of traffic when operating near streets or along curbs.

Thoroughly inspect the area where the equipment is to be used and remove all doormats, sleds, boards, toys, wires and other foreign objects.

Disengage all clutches and shift into neutral before starting the engine.

Use extension cords and receptacles as specified by the manufacturer for all units with electric drive motors or electric starting motors.

Operation

Disengage all controls before starting engine. Never leave a running unit unattended. Always stop

engine and remove key before leaving unit to prevent unauthorized use.

Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times.

Moving and/or rotating parts can cut off body parts such as fingers or a hand. NEVER place your hands, other body part or clothing near any moving parts while unit is running.

Always keep hands away from all pinch points. Do not touch parts which might be hot from operation.

Allow parts to cool before attempting to maintain, adjust or service.

Thrown objects can cause injury. Check for weak spots on docks, ramps or floors. Avoid uneven work areas and rough terrain and stay alert for hidden hazards.

Exercise extreme caution when operating on or crossing gravel drives, walks or roads. Stay alert for hidden hazards or traffic.

EN – 4

After striking a foreign object, stop the engine, remove the wire from the spark plug, disconnect the cord on electric motors, thoroughly inspect the snow thrower for any damage, and repair the damage before restarting and operating the snow thrower.

If the unit should start to vibrate abnormally, stop the engine and check immediately for the cause. Vibration is generally a warning of trouble.

Stop the engine whenever you leave the operating position, before unclogging the auger / impeller housing or discharge chute, and when making any repairs, adjustments or insp ec tions.

When cleaning, repairing or inspecting the snow thrower, stop the engine and make certain the auger / impeller and all moving parts have stopped. Disconnect the spark plug wire and keep the wire away from the plug to prevent someone from accidentally starting the engine.

Do not run the engine indoors, except when starting the engine and for transporting the snow thrower in or out of the building. Open the outside doors; exhaust fumes are dangerous.

Never operate the snow thrower without proper guards, and other safety protective devices in place and working.

Always stand clear of the discharge area when operating this unit.

Never direct the discharge toward people or areas where injury or property damage can occur from thrown objects. Keep children and others away.

Do not overload the machine capacity by attempting to clear snow at too fast a rate.

Never operate the machine at high transport speeds on slippery surfaces. Loo k behind and us e care when operating in reverse.

Do not operate in reverse unless absolutely necessary. Always back up slowly and look down and behind before and while backing.

Do not carry passengers. Disengage attachment when not in use and when

traveling from one work area to another. Disengage power to the auger / impeller when snow

thrower is transported or not in use. Use only attachments and accessories approved by the

manufacturer of the snow thrower (such as wheel weights, counterweights or cabs).

This product is equipped with an internal combustion engine. Do not use unit on or near any unimproved, forest-covered or brush-covered land unless exhaust system is equipped with a spark arrester meeting applicable local, state or federal laws. A spark arrester, if used, must be maintained in effective working order by operator.

Never operate the snow thrower without good visibility or light. Always be sure of your footing, and keep a firm hold on the handles. Walk; never run.

Never operate unit after or during the use of medication, drugs or alcohol. Safe operation requires complete and unimpaired attention at all times.

Never allow anyone to operate this unit when their alertness or coordination is impai r ed.

Never touch a hot engine or muffler. Avoid contact with sharp edges; sharp edges can cut. Do not throw snow higher than necessary.

Clearing a Clogged Discharge Chute

Hand contact with the rotating auger / impeller inside the discharge chute is the most common cause of injury associated with snow throwers. Never use your hand to clean out the discharge chute.

To clear the chute:

1. SHUT THE ENGINE OFF!

2. Wait 10 seconds to be sure the auger / impeller

blades have stopped rotating.

3. Always use a clean-out tool, not your hands.

Maintenance and Storage

Secure unit so it will not tip over during maintenance. Before cleaning, removing clogs or making any

inspections, repairs, etc., disengage clutch(es), stop engine, remove key, allow moving parts to stop and hot parts to cool.

Check shear bolts and other bolts at frequent intervals for proper tightness to be sure the equipment is in safe working condition.

Check clutch and brake operation frequently. Do not change engine governor settings and do not over-

speed engine. Adjust and service as required. Motion of drive wheels

and auger / impeller must stop quickly when clutch levers are released.

Always maintain unit in safe operating condition. Damaged or worn out muffler can cause fire or explosion.

Keep unit free of ice or other debris. Clean up oil or fuel spills.

Always keep protective structures, guards, and panels in good repair and secured in place. Never modify or remove safety devices.

Never store the machine with fuel in the fuel tank inside a building where ignition sources are present such as hot water heaters, space heaters or clothes dryers. Close fuel valve and allow the engine to cool completely before storing in any enclosure or covering the unit.

EN – 5

Always refer to operator's manual for important details if the snow thrower is to be stored for an extended period.

Maintain or replace safety and instruction labels as necessary.

Run the machine a few minutes after throwing snow to prevent freeze-up of the auger / impeller.

Personal Protection

Do not operate the equipment without wearing adequate winter garments. Avoid loose fitt ing clothing that can get caught in moving parts. Wear footwear that will improve footing on slippery surfaces.

Wear adequate safety gear, including safety glasses with side shields and protective gloves.

Do not wear loose clothing or jewelry, and tie back hair that may get caught in rotating parts.

NEVER attempt to unclog or clean unit while engine is running. Rotating auger / impeller can cause serious injury.

Protect eyes, face and head from objects that may be thrown from unit. Wear appropriate hearing protection.

Always wear safety glasses or eye shields during operation or while performing an adjustment or repair to protect ey es f rom f orei gn o bje cts t hat may be thr ow n fr om the machine.

Slope Operation

Exercise extreme caution when operating on slopes. DO NOT operate on steep slopes. DO NOT clear snow across the face of slopes; go up and down. Keep all movement on slopes slow and gradual.

Use a slow speed to avoid stops or shifts on slopes. Avoid starting or stopping on a slope. Do not park unit on a slope unless absolutely necessary. When parking on a slope always block the wheels.

Do not operate near drop-offs, ditches, or embankments. Unit can suddenly turn over if a wheel is over the edge of a cliff or ditch, or if an edge caves in.

Never fill fuel 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.

When prac ti ca l, r e mo v e ga s -po w e re d e qu i pm e nt f r o m the truck or trailer and refuel it on the ground. If this is not possible, then refuel on a trailer with a portable container, rather than from a gasoline dispenser nozzle.

CHECKING TROUBLE CODES

Figure 154

Figure 155

TROUBLE CODE DIAGNOSTICS

The blinking red LED light on the ECU displays trouble codes. Its sequence indicates a particular system malfunction by blinking as many times as the first digit of a trouble code, pausing, and then blinking as many times as the second digit of a trouble code.

For example, the red LED will indicate low fuel pressure (27) by blinking twice, pausing, and blinking seven more times.

IMPORTANT: Be aware that more than one trouble code may be present.

A blinking green LED indicates the ECU processor is operating correctly, even if a sub-component of the ECU (e.g.: barometric pressure sensor) has failed. A constant illuminated green (not blinking) LED indicates the ECU may be experiencing a low battery voltage condition or need replacement. See EFI Trouble Code Identification on page 60.

Visually inspect the red LED to verify trouble codes. To read trouble codes more easily, place a mirror under the

ECU to view LED reflection. IMPORTANT: If no trouble code is present, but engine is

not operating normally, See Diagnostics for Non-Trouble Codes on page 64.

NOTICE: Before performing diagnostic tasks, be aware of the screw on the bottom of the throttle body that adjusts the servo offset. The servo offset calibrates the throttle body at the factory using a flow bench and should NEVER be touched. If it is tampered with, the engine will run poorly and void the warranty. See Figure 155.

Code 16: Low Battery Voltage

1. Charge the battery. Refer to Operator’s Manual.

2. Start the engine. Refer to Operator’s Manual.

3. Check charging system at the battery.

a. With a multi-meter set to volts DC, back probe the

battery terminals. At full throttle (3600 RPM), the

reading should be 7.5 – 8.4 volts DC. If voltage measures less than 7.5 volts, check charging system at the engine. Advance to step 5.

IMPORTANT: If the engine is cold, it is normal for the engine speed to be 100 – 200 RPM higher until operating temperature is reached.

4. Stop the engine. Refer to Operator’s Manual.

b. Check the battery. With the engine off, the battery

voltage should be 7.2 – 8.4 volts DC. See Figure 156. If voltage measures less than 7.2 volts after charging, replace battery.

EN – 61

5. Back probe the engine stator output connector. See

Figure 156

Temperature

Sensor

Figure 157.

a. Start the engine. Refer to Operator’s Manual. b. A t full throttl e (3600 RPM ), the sta tor output MUST

be 11.5 – 14 volts AC. If AC voltage measure less than 11.5 volts, remove flywheel and replace stator.

If stator output is within range and battery is not charging, check ECU wiring for damage. Replace ECU if necessary.

Code 21: Barometer Sensor

See Figure 152. This trouble code indicates the barometric pressure sensor

has failed. When the barometric sensor fails, the engine will not adjust to altitude changes, but will continue to operate at a default altitude of 800 feet above sea level.

Engine may continue to operate with a failed barometric pressure sensor, but may not operate at optimal performance. If barometric pressure sensor fails, replace ECU.

Code 22: Engine Temperature Sensor

See Figure 152. If the sensor is damaged or has failed, the engine may not

run smoothly because the ECU cannot adjust for engine temperature changes.

The temperature sensor and engine components can be visually inspected for engine temperature issues:

1. Check engine cooling fan and engine cooling fins for debris or damage.

2. Check the temperature sensor wiring from the throttle body to the mounting boss on the side of the cylinder. Make sure connection is secure. See Figure 158.

3. Check wiring and connection from the throttle body to the ECU for damage.

If no damage is visible, replace throttle body assembly.

EN – 62

Code 27: Low Fuel Pressure

Figure 159

Inline Fuel Filter

Figure 160

Fuel Pump Wires

Figure 161

Low fuel pressure is usually a result of an empty fuel tank, but could also be from a clogged fuel filter or faulty fuel pump.

Attempt engine start and check for trouble code reoccurrence after each of the following steps. Refer to Operator’s Manual for engine starting instructions.

1. Check fuel level and fill fuel tank completely if not already full.

2. Check fuel lines to ensure there are no leaks or kinks.

3. Check inline fuel filter for debris and blockage. See Figure 159.

CAUTION: AVOID INJURY. Fuel lines are pressurized; wear safety glasses.

4. Check fuel pump wiring to ensure it is connected correctly. See Figure 160.

See Figure 161.

5. Remove the fuel pump wires, turn ignition key to the ON position and measure the fuel pump voltage. Voltage output should measure 7.2 – 8.4 volts DC.

IMPORTANT: Fuel pump voltage MUST be measured within 30 seconds of the ignition switch being turned to the ON position.

If voltage measures less than 7.2 volts, check the battery voltage by probing the green wire on the ECU 12-pin connector. See Figure 162.

• If low voltage or no voltage is present, replace the

ECU.

• If voltage is present, inspect the green wire between

the 12-pin connector and throttle body for a pinched or broken wire. If the wire has no damage, replace the throttle body assembly.

• If voltage measures 7.2 – 8.4 volts, turn ignition key

to OFF position, reconnect fuel pump wires and turn key back to ON position. Fuel pump should make a “humming” noise.

If fuel pump is silent, the pump may have failed. Check fuel pump:

1. Drain fuel from fuel system and tank. See Draining Fuel System on page 7.

2. Remove pump from tank.

3. Reconnect pump wires.

4. Turn the ignition key to the ON position and listen for a “humming” noise.

If fuel pump is silent, replace fuel pump. If voltage is within range and fuel pump is operating

normally, the fuel pressure sensor is defective. Replace the throttle body assembly. S ee Figure 16 7.

This trouble code will activate if ECU detects a higher voltage from the stator.

1. Start the engine. Refer to Operator’s Manual.

2. Set a multi-meter to volts AC and probe the red and black stator connector wire. The output should be

11.5 – 14 volts AC at full throttle (3600 RPM).

If stator output measures over 14 volts, replace stator. If output is within range, advance to step 3. See Figure 157.

IMPORTANT: If the engine is cold, it is normal for the engine speed to be 100 – 200 RPM higher until operating temperature is reached.

3. Set a multi-meter to volts DC and probe the battery connector at the battery terminals. With the engine running at full throttle (3600 RPM), the output should be 7.2 – 8.4 volts DC.

If DC output is higher than 8.4 volts, replace ECU. See Figure 156.

If DC output is within range and red trouble code persists, replace ECU.

DIAGNOSTICS FOR NON-TROUBLE CODES

Engine Starts and Loses Power

If the engine starts and loses power immediately, this is usually an indication that the ECU does not detect an RPM signal. The RPM signal is generated by the stator, which also powers the hand warmers, headlight and charges the ECU battery.

A common cause for RPM signal failure may be a ground short in the AC output wire coming from the stator to the ECU. Another possible cause may be a defect in the engine-charging system.

Engine No-Start Condition

If the engine does not start, check for system power.

1. Check spark plug.

2. Check the battery. Battery should have 7.2 – 8.4 volts

If battery measures below specification after charging, replace battery.

3. Check the ECU status. With battery voltage between

IMPORTANT:

LEDs may appear dim or will not illuminate red or green LEDs.

EFI Trouble Code Identification on page 60.

4. Check fuel pump output.

a. Stop engine, remove key and wait for all moving parts

to stop and for hot parts to cool.

b. Disconnect the spark plug cap and remove debris

from the spark plug area. c. Remove spark plug. d. Inspect the spark plug. Spark plug gap MUST be

0.7 – 0.8 mm (0.027 – 0.030”). Replace if the

electrodes are worn or if the insulator is cracked or

chipped. e. Position spark plug against engine block and pull

recoil starter handle to check for spark. If no spark is

present, replace spark plug. f. Reinstall spark plug and finger tighten. Turn an

additional 1/4 turn after spark plug is seated. g. Reinstall spark plug cap and make sure it is correctly

positioned onto the spark plug.

DC, depending on when the battery was most recently charged. Extremely low voltage could cause a no-start condition without triggering a trouble code. If battery has low voltage, connect battery charger to battery. Also check the inline fuse on the battery cable.

7.2 – 8.4 volts DC, check if the green ECU status light is blinking at a consistent rate.

If battery measures below 7.0 volts, ECU

If green LED is constant, (not-blinking) see

a. Remove the heater box. b. Check voltage at fuel pump. See Code 27: Low Fuel

Pressure on page 63 for voltage readings. c. Remove fuel hose from fuel pump outlet and attach a

suitable length of fuel hose to the fuel pump outlet

that can safely reach a clearly marked fuel container.

d. With battery voltage between 7.2 – 8.4 volts DC, turn

the key to the ON position for 10 seconds to pump fuel into the container. Fuel should measure approximately 160 mL (5 oz.).

If fuel amount measures less than 160 mL, remove the fuel pump and check the pre-filter for blockage. If filter is clean, replace fuel pump. See Figure 163.

b. Set a multi-meter to volts DC and probe each

terminal with the red probe and contact the black

probe to engine block. With the ignition key in the ON

position, each terminal should measure

7.2 – 8.4 volts DC. See Figure 165. If voltage is within range and the fuel injector is not operating correctly with the key in the ON position, replace throttle body assembly .

IMPORTANT: If replacing fuel pump, wet the fuel system:

a. Fill fuel tank full. b. Cycle ignition key to the ON position, then to the OFF

position. Repeat. IMPORTANT: Cycling the ignition key multiple times may inject excessive amounts of fuel into the throttle body and “flood” the engine. A flooded engine may require more starting attempts than normal.

5. Remove connector to the injector.

a. Move gray slide upward until it stops. Gently

compress gray slide and remove connector. See

Figure 164.

EN – 65

c. If no voltage is present at the injector, check voltage

Figure 166

Figure 167

at both the red and white wires on the12-pin ECU

connector. See Figure 166.

If no voltage is present at the ECU, replace ECU. If voltage is present at the ECU, check wires for kinks or damage. If damage is present repair wires if possible, or replace throttle body. See Figure 167.

Surging Run Condition

If the AC output wire from the engine charging system is damaged, it may cause an intermittent short. This will result in erratic running such as the engine over revving or “popping” through the exhaust.

1. Check the engine wiring and wiring under the handlebar to verify that it is not damaged.

Engine Speed Does Not Change

If engine speed does not change when using the potentiometer (throttle control), check the following:

1. Set a multi-meter to ohms and measure the potentiometer resistance. See Figures 168 and Figure 169.

a. Unplug the 14-pin connector from the ECU. b. Position the red probe on the terminal of the red wire

at the potentiometer (Pin 5 in Figure 168) and the black probe on the terminal of the green / white wire.

The potentiometer output should measure 0 – 5000 ohms. If ohm reading measures close to 0 at full throttle and close

to 5000 at low-idle, potentiometer is operating normally. If ohm reading stays constant at either position, replace potentiometer.

the ECU.

b. Position the red probe on the terminal of the red wire

at the potentiometer (Pin 5 in Figure 168). Also see

Figure 169. c. Position the black probe on the engine block. d. Turn ignition key to ON position. e. Turn the potentiometer from low-idle to full throttle.

Voltage to the red wire should measure 4.90 – 5.0 volts DC at both low-idle and full throttle positions.

If voltage measures less than 4.90, replace ECU.

3. With a multi-meter, measure the volts DC of the green / white wire. See Figure 170.

a. With engine off, position the red probe on the

terminal of the green / white wire. b. Position the black probe on the engine block. c. Turn ignition key to ON position. d. Turn the potentiometer from low-idle to full throttle.

Voltage to the green / white wire should measure close to

0.01 volts DC at low-idle and close to 5.0 volts at full throttle.

If voltage does not vary between low-idle and full throttle, replace the ECU.
