Safety Instructions

FOR DOUBLE-INSULATED LAWN MOWERS

1. Replacement parts 
   When servicing this unit, use only identical replacement parts. Replace or repair damaged cords immediately.
2. Polarized plug 
   Polarized appliance connections reduce the risk of electric shock. This mower has a polarized plug (one blade is wider than the other) and will require the use of a polarized extension cord. There is only one way the mower’s plug will fit into a polarized extension cord. If the plug does not fit fully into the extension cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord. A polarized extension cord will require the use of a polarized wall outlet. There is only one way the plug will fit into a polarized wall outlet. If the plug does not fit fully into the wall outlet, reverse the plug. If the plug still does not fit, contact a qualified electrician to install the proper wall outlet. Do not change the equipment plug, extension cord receptacle, or extension cord plug in any way.

• Hot surfaces (i.e. ,the motor) may ignite flammable or combustible items and cause a fire or explosion, which can result in serious bodily injury. Keep the mower a safe distance away from flammable or combustible items until surfaces that are hot have completely cooled. Do not store the mower near flammable or combustible items.
• A damaged blade or worn blade nut may break off the mower assembly and cause serious injury. Replace the damaged blade or blade nut before using the mower.

Electrical Safety

1. . Ground fault circuit interrupter (GFCI) protection should be provided on the circuit(s) or outlet(s) to be used for the lawn mower. Receptacles are available having built-in GFCI protection and may be used for this measure of safety.
2. To prevent electric shock, use only with an extension cord suitable for outdoor use, such as SW, SOW, STW, STOW, SJTW, or SJTOW. Before use, check that the extension cord is in good condition. When using an extension cord, make sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage, resulting in loss of power and overheating.
3. To reduce the risk of electric shock, this appliance has a polarized plug (i.e.,o ne blade is wider than the other). Use this appliance only with a polarized, UL-listed (CSA certified in Canada) extension cord recommended for outdoor use. The appliance plug will fit into a polarized extension cord only one way. If the appliance plug does not fit fully into the extension cord, reverse the plug. If the plug still does not fit, obtain a correct polarized extension cord. A polarized extension cord will require the use of a polarized wall outlet. The extension cord plug will fit into the polarized wall outlet only one way. If the plug does not fit fully into the wall outlet, reverse the plug. If the plug still does not fit, contact a qualified electrician to install the proper wall outlet. Do not modify the appliance plug, extension cord receptacle, or extension cord plug in any way.
4. To prevent the appliance cord from disconnecting from the extension cord during operation, make a knot with the two cords as shown in Table 1.
   • Table 1. Method of Securing Ean xtension Cord
5. Do not abuse the cord. Never pull the lawn mower by the cord or yank the cord to disconnect it from the receptacle. Keep the cord away from heat, oil, and sharp edges.

   • Proceed as shown in Fig. 15, always working away from the electric extension cord.
3. Be sure to check the blade periodically for signs of wear and sharpen it at least once per year, as described in the maintenance section.

NOTE
A sharp blade will greatly enhance the performance of the mower, especially when cutting tall blades of grass.

Overload Protection

The motor is equipped with a thermal switch that cuts out when the motor is overloaded and switches on again automatically after a short cool-down period. The mower blade will continue to rotate for a brief period after the unit has been switched off. Do not tilt or carry the unit while the motor is still running, and do not touch the blade while it is still rotating. Failure to comply could result in severe personal injury.

Maintenance

General

• Always keep the mower clean and free of grass, dirt, or other debris.
• Keep the handles dry, clean, and free of oil and grease.
• After each cutting session, remove accumulated grass clippings and debris using either a dry cloth or a handbrush. You may also clean the equipment with a damp cloth and some soft, non-abrasive soap. Do not use cleaning agents or harsh solvents, as they may damage the equipment’s plastic components. Make sure that no water penetrates the equipment’s interior, as intake of water can destroy the switch/plug mechanism and the electric motor.
• Do not clean the lawn mower with running water, particularly with high-pressure water.
• Check all nuts, bolts, and screws for proper tightness before each use.
• Frequently inspect the grass bag assembly for signs of wear and replace immediately with a genuine Snow Joe® + Sun Joe® part if damage is found.
• Replace excessively worn or damaged parts immediately.
• To maximize your mower’s longevity, all screwed parts, including the wheels and axles, should be cleaned and lubricated. There are no parts inside the equipment that require additional maintenance or lubrication.

Blade Maintenance

The mower blade is sharp and can cause severe personal injury if handled incorrectly. Wrap the blade or wear protective gloves, and use extra caution when handling. The steel blade is designed to provide a fine cut in long or tough grass. Deterioration in the quality of the cut indicates blade wear or damage. Follow these steps to determine if the blade needs to be resharpened or replaced:

1. . Disconnect the electrical supply to the mower
2. Turn the mower on its side to expose the underside of the blade housing.
3. Check the blade
   • If the blade is blunt or has minor wear, then resharpen. Please call Snow Joe® + Sun Joe® customer service for assistance at 1-866-SNOWJOE (1-866-766-9563).
   • If the blade shows signs of major wear or damage (i.e., gouged, bent), then replace it. Please call Snow Joe® + Sun Joe® customer service for assistance at 1-866-SNOWJOE (1-866-766-9563).

An excessively vibrating mower indicates that the blade is not properly balanced or has become deformed from striking an object. In this case, the blade must be repaired or replaced. Please follow the proper maintenance procedures for blade care or call the Snow Joe® + Sun Joe® customer service center for assistance at 1-866-SNOWJOE (1-866-766-9563).

Blade Replacement
