IMPORTANT SAFETY WARNINGS
TO REDUCE RISK OF INJURY: Before any use be sure everyone using this product reads and understands all safety instructions and other information contained in this manual.
CAUTION: Wear appropriate personal hearing protection during use. Under some conditions and duration of use, noise from this product may contribute to hearing loss.
Save these instructions and review frequently prior to use and in instructing others.
WARNING: When using electric appliances, basic safety precautions should always be followed to reduce risk of fire, electric shock, and personal injury, including the following:
READ ALL INSTRUCTIONS
GENERAL SAFETY
CHECK FOR DAMAGED PARTS – Before further use of the product, any part that is damaged should be carefully checked to determine that it will operate properly and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other condition that may affect its operation. Any part that is damaged should be properly repaired or replaced. For assistance call our customer service help line at 1-800-633-1501.
AVOID DANGEROUS ENVIRONMENTS – Do not operate in gaseous or explosive atmospheres. Motors in these products normally spark, and the sparks might ignite fumes.
KEEP CHILDREN AWAY – All visitors, children and pets should stay at a safe distance from the work area.
DRESS PROPERLY – Don’t wear loose clothing or jewelry and wear protective hair covering to contain long hair. They can be caught in moving parts. Wear safe, sturdy, nonskid footwear. Maintain good footing at all times, especially on slopes.
USE SAFETY GLASSES – Wear safety glasses with side shields or goggles that are marked to comply with ANSI Z87.1 standard when operating this product.
DOUBLE INSULATION – The snow thrower has double insulation. This means that all external metal parts are insulated from the electrical supply. This is achieved by introducing an insulation layer between electrical and mechanical parts. The double insulation guarantees you the greatest possible safety.
WARNING: Use outdoor extension cords marked SW-A, SOW-A, STW-A, STOW-A, SJW-A, SJTW-A, or SJTOWA. These cords are rated for outdoor use and reduce the risk of electric shock.
POLARIZED PLUGS- To reduce the risk of electric shock, this product has a polarized plug. Polarized connections will fit together only one way.Make sure that the receptacle end of the extension cord has large and small blade slot widths. If the plug does not fit fully into the extension cord, reverse the plug. If it still does not fit, obtain a suitable extension cord. If the extension cord does not fit fully into the outlet, contact a qualified electrician to install the proper outlet. Do not change the plug on the tool or the extension cord in any way.
EXTENSION CORD. Make sure your extension cord is in good condition. When using an extension cord be sure it is heavy enough to carry the current your product will draw. An undersized extension cord will cause a drop in line voltage resulting in loss of power and overheating. The following table shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.
It is possible to tie two extension cords together in a knot to prevent them from becoming disconnected during use. Make the knot as shown, then connect the plug end of the power cord into the receptacle end of the extension cord.
This method can also be used to tie two extension cords together.
Use one of the plug-receptacle retaining straps or connectors described in this manual.
WARNING: Keep all connections dry and off the ground. Do not touch plug with wet hands. Failure to do so can result in serious personal injury or death.
Be aware of the extension cord while operating the snow thrower. Be careful not to trip on the cord. Always keep the cord away from the auger.
GENERAL SAFETY
GROUND FAULT CIRCUIT INTERRUPTER (GFCI) protection should be provided on the circuit or outlet to be used for the snow thrower. Receptacles are available having built-in GFCI protection and may be used.
WARNING: Never put your hands near the auger to remove snow, sticks or other debris. Blocked auger can “spring back” when cleared and may cause personal injury even when the snow thrower is stopped. Always use a wooden stick such as a broom handle to clear blockages.
DISCONNECT UNIT from the power supply when not in use or when servicing or cleaning. Do not leave unattended.
DON’T ABUSE CORD – Never carry this product by the cord or yank the cord to disconnect from the receptacle. Keep cord from heat, oil, and sharp edges.
USE RIGHT APPLIANCE – Do not use this product for any job except that for which it is intended.
DO NOT OVERLOAD the snow thrower by using at too fast a rate to clear the snow. The snow thrower will perform better and safer at the rate for which it was designed.
DON’T OVERREACH – Guide the snow thrower at a walking pace only. Keep proper footing and balance at all times.
LIGHTING – Only operate your snow thrower in daylight or good artificial light.
STORE IDLE UNIT INDOORS-When not in use, the snow thrower should be stored indoors in a dry area out of reach of children.
MAINTAIN UNIT WITH CARE-Keep clean for best performance and to reduce the risk of injury. Inspect extension cord periodically and replace if damaged.
Keep handles dry, clean and free from oil.
Do not operate the snow thrower on a slope that is too steep for safe operation. When on slopes, slow down and make sure you have good footing.
Before starting the snow thrower make sure the auger is not touching any object and is free to move.
Do not attempt to clear snow from a gravel or crushed rock surface. This product is only intended for use on hard, flat surfaces free of sand, stone and debris, wires or any other objects.
Operation of the snow thrower in the hand-held position is unsafe except in accordance with the special instructions for such use provided in the operator’s manual.
CAUTION: Never throw snow towards people, pets or cars and never allow anyone in front of the snow thrower while in operation.
Objects that might clog the snow thrower or cause other damage can be hidden in the snow. Clear the area of doormats, sleds, boards, wires and other debris prior to use.
If the auger strikes a foreign object, stop the snow thrower and examine it for signs of damage. Make any necessary repairs before restarting and continuing to work.
STAY ALERT – Watch what you are doing. Use common sense. Do not operate the snow thrower when you are tired or under the influence of drugs, alcohol or medications.
If the snow thrower starts to vibrate abnormally, turn it off immediately and check for the cause. Vibration is generally a warning of trouble.
Always turn off the snow thrower, wait until the auger comes to a complete stop and disconnect from the power supply before carrying out maintenance or repairs.
Never operate the snow thrower without proper guards and other safety protective devices in place and working.
When servicing use only identical replacement parts.
CAUTION: Auger does not stop immediately after the snow thrower is turned off.
CAUTION: Risk of injury. This snow thrower is capable of causing serious injury. Do not put hands, feet or any body part or clothing near the rotating auger.

OPERATING
Turning On and Off
WARNING: The auger starts rotating immediately after the snow thrower is switched on. Keep hands and feet away from the auger.
To switch ON, make sure the auger is not touching any surface. Press down and
hold the safety lock off button
(1). While holding down the button pull back on bail wire
(2). Once the snow thrower is started you can release the safety lock off
button.
To switch off simply release the bail wire.
LED HEADLIGHTS
LED headlights are located on the upper handle to illuminate your path when using the snow blower in low light conditions.
Power on the snow thrower, press on/off button to turn the headlights on and off. (See Fig 16)
Removing snow
Before starting work, thoroughly inspect the area where the equipment is to be
used and remove all doormats sleds, boards, wires and any other foreign
objects.
Check the condition of the snow thrower before operating it to ensure that the auger turns freely.
Check the auger for wear and tear at regular intervals.
Make sure all fasteners on the snow thrower (screws, nuts, etc.) are fully
tightened.
Position the discharge chute so that snow will discharge in a safe direction. Do not direct the discharge towards people or areas where property can be damaged. Keep children, pets and others away for the work area. Do not walk in front of the snow thrower when it is running.
Direct the discharge to the right or left by turning the discharge chute with the chute crank. The chute can be adjusted up to 180 degrees.
The chute deflector on the top of the discharge chute controls the height of the discharge. Loosen both of the knobs to raise or lower the deflector to the desired height and tighten the knobs to secure the deflector.
NOTE: Do not over-tighten the knobs.
For the most efficient snow removal throw the snow downwind and slightly
overlap each swath.
Push the snow thrower forward at a comfortable rate of speed, yet slow enough to clear the path completely. The width and depth of the snow determines your forward speed.
Start your clearing path near the electrical outlet and work outward, throwing snow in a back and forth motion.
When turning at the end of a swath, step over the cord and turn the snow thrower. Use the wheel on one side as the pivot point. Slightly tilt the snow thrower on this pivot point while turning.
The snow thrower can remove up to 12 inches deep in one pass.
Clear snow often, before it gets too deep. It is best to remove the snow as soon as possible after it falls.
Some parts of the snow thrower may freeze under extreme temperature conditions. If parts freeze while the snow thrower is in use, stop the snow thrower, unplug the extension cord and inspect for frozen parts. Free all parts of ice before restarting or operating the snow thrower. Do not attempt to operate the snow thrower with frozen parts or try to force controls that are frozen.
After clearing the snow, continue to run the snow thrower for a few minutes to prevent ice from freezing on moving parts. Then switch off the motor, wait for all moving parts to stop, and wipe the ice and snow from the snow thrower with a clean rag.
WARNING: To avoid serious personal injury, do not use hands or feet to unclog the chute.
Before unclogging the chute, shut off the snow thrower and disconnect from the power supply. Wait for the auger to stop turning. Clean out the chute with a wooden stick such as a broom handle.
If the snow thrower should start to vibrate abnormally, immediately stop the motor and check for the cause. Vibration is generally a warning of trouble.
Look behind and use care when backing up with the snow thrower.
For large areas a definite pattern of operation is required to thoroughly clean an area of snow. These patterns will avoid throwing snow in unwanted places as well as eliminating a second removal of snow.
Pattern A: Throw the snow to the right or left side where it is possible. For areas such as a long driveway it is advantageous to start in the middle. Plow from one end to the other, throwing snow to both sides.
Pattern B: If the snow can only be thrown to one side of the area to be cleared, start on the opposite side.
MAINTENANCE
Before carrying out maintenance operations, disconnect power supply.
Regular cleaning and maintenance of your snow thrower will ensure efficiency and prolong the life of the product.
Check all fasteners at frequent intervals for proper tightness to be sure the snow thrower is in safe working condition.
After each use, let the motor run for a few minutes so that moving parts do not freeze. Then shut off the motor, wait for all moving parts to stop, and wipe the ice and snow from the snow thrower. Rotate the chute crank several times to remove snow.
Only use a cloth soaked with hot water and a soft brush to clean the snow thrower. Never wet or spray water on the machine!
Do not use detergents or solvents as these could cause irreparable damage to the snow thrower. Chemicals can destroy the plastic parts.
To protect the snow thrower from corrosion when storing for long periods, lightly oil the metal parts.
Store the snow thrower in a dry area out of reach of children.
For the user’s safety, worn or damaged parts must be replaced. Replace with original replacement parts only.
Parts from another snow thrower may not fit properly causing an unsafe situation.
Lubricating the snow thrower
You do not need to lubricate the snow thrower. All of the bearings are sealed
and were lubricated at the factory for the life of the snow thrower.
Replacing the rubber plates on auger
Detach the worn rubber plate by removing the two sets of nuts, bolts, and
washers used to secure it.
Install the new rubber plate.
Insert the bolt with the small flat washer into the corresponding holes on each end of the rubber plate.
Use a large flat washer and locknut to secure the bolt on each end.
Install the other rubber plate in the same manner.
Replacing the scraper
The scraper is located at the base of the snow thrower beneath the auger
housing.
Remove the screws that secure the scraper to the snow thrower.
Install the new scraper and fasten it securely with the screws. (See Fig 17)
Replacing the auger belt
Contact Earthwise for new belts and installation kit.
Under normal operating conditions it should not be necessary to replace the
auger belt. However, should the auger jam or malfunction the belt could be
damaged. To replace the belt follow these instructions.
Belt drive system structure (See Fig 18)
1. Open the left side plate by removing three screws. (Fig. 19)
2. Use your right hand to turn the rib side of the belt up and pull upwards while turning the auger pulley counterclockwise with your left hand. The belt can be easily removed from the pulley. (Fig. 20 – 21)
3. Put the belt on the drive pulley first and then place the belt at the lower end of the auger pulley. (Fig. 22)
4. Use right hand to press the belt with ribbed side down. (Fig. 23)
5. While holding the belt down with your right hand use your left hand to turn the auger forward so that the auger pulley rotates in a clockwise direction. (Fig. 24)
6. Keep pressure on the belt with your right hand (rib side down and flat side up) while rotating the auger. The belt will be gradually pushed down onto the pulley. When the belt is seated on the pulley, adjust it so that the ribs of the belt match the grooves on the pulley. (Fig. 25 – 28)
7. After belt is installed, replace the side plate and secure it with the three screws. (Fig. 29)
