⚠ WARNING! Do not operate without the entire grass collection bag, discharge guard, rear flap, or other safety protective devices in place and in proper working order.

⚠ WARNING! The use of any other accessory or attachment might increase the risk of injury.

⚠ WARNING! To reduce the risk of injury, inspect the grass collection bag frequently and replace with recommended replacement if there are signs of wear or deterioration.

Before using the lawn mower, take the time to familiarize yourself with the controls, especially how to stop the lawn mower in an emergency. The only individuals who should use the lawn mower are those who have a thorough understanding

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.

⚠ WARNING! Contact with moving parts may cause entanglement, dismemberment, or other serious bodily injury. Always keep body parts (i.e. hands, feet) a safe distance away from moving parts. Ensure all covers and guards are securely in place before use.

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 lawn mower a safe distance away from flammable or combustible items until surfaces that are hot have completely cooled. Do not store the lawn mower near flammable or combustible items.

A damaged blade or worn blade nut may break off the lawn mower assembly and cause serious injury. Replace the damaged blade or blade nut before using the lawn mower.

FOR ALL LAWN MOWERS

1. Avoid dangerous conditions – Do not use the lawn mower in the rain or when the grass is damp or wet.
2. Keep children, bystanders, and pets away – Always keep children and spectators a safe distance away from the lawn mower during operation and as the machine cools.
3. Dress properly - Always wear personal safety near

1. Disconnect the lawn mower – Disconnect the lawn mower from the power supply when it is not in use, before servicing, when changing accessories, and when performing any other maintenance task.
2. Store idle lawn mower indoors – When not in use, the lawn mower should be stored indoors in a dry, locked place out of the reach of children.
3. Maintain the lawn mower with care – Keep cutting edges sharp and clean for best and safest performance.

Inspect the lawn mower cord periodically and if damage is found have it repaired by an authorized service facility. Extension cords should also be inspected periodically and immediately replaced if damaged. Keep handles dry, clean, and free from oil and grease.

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 reduce the risk of electric shock, this appliance has a polarized plug (i.e. one 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

WARNING

Electric shock may cause SEVERE INJURY or DEATH. Heed these warnings:

• Do not allow any part of the electric lawn mower to make contact with water while it is in operation. If the appliance becomes wet while turned off, wipe dry before starting.
• Use only a UL-, CSA-, or ETL-rated extension cord for outdoor, all-weather use.
• Do not use an extension cord over 100 ft (30 m).
• Do not touch the appliance or its plug with wet hands or while standing in water. Wearing rubber boots offers some protection.

Double-Insulated Appliances

In a double-insulated appliance, two systems of insulation are provided instead of grounding. No grounding means are provided on a double-insulated appliance, nor should a means for grounding be added to the appliance. Servicing a double-insulated appliance requires extreme care and knowledge of the system, and should be performed only by qualified service personnel at an authorized Snow Joo ^® + Sun Joo ^® dealer. Replacement parts for a double-insulated appliance must be identical to the parts they replace. A double-insulated appliance is marked with the words "Double Insulation" or "Double Insulated." The symbol (square within a square) may also be marked on the appliance.

BLE-INSULATED: GROUNDING NOT REQUIRED. WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS.

This electric lawn mower is double-insulated, eliminating the need for a separate grounding system. Use only identical replacement parts. Read the instructions before servicing double-insulated appliances. Use this lawn mower only as described in this manual.

Mowing Tips

⚠ WARNING! Inspect the area prior to mowing and remove all the stones, sticks, wires, and other debris that might be thrown by the rotating blade.

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

• 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.
• In order to prevent electric shock, do not operate the lawn mower in damp or wet conditions.
• Do not mow in a circle. Travel back and forth across the lawn following the path outlined below (Fig. 15).

• When cutting thick grass, reduce your walking speed in order to allow for a more effective cut and a proper discharge of the clippings. For a healthy lawn, always cut off one-third or less from the total length of the grass.

• While mowing, make sure that the electric cable is always behind you and resting on the area of grass already cut.

• The lawn will look better if it is always cut to the same height and in alternate directions.
• When crossing any graveled area, release the switch bar lever to turn off the lawn mower. The stones can be picked up and thrown by the rotating blade.
• Set the lawn mower to the highest cutting height when mowing on uneven ground or in tall weeds.

⚠ WARNING! If you strike a foreign object, stop the motor and disconnect the power cord. Thoroughly inspect the lawn mower for any damage. Repair any damage before operating the lawn mower.

Maintenance

⚠ WARNING! Before cleaning, repairing, or inspecting the lawn mower, disconnect the power supply to the unit and verify that all moving parts have come to a complete stop.

General

• Always keep the lawn 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 hand brush. You may also clean the equipment with a damp cloth. 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.

Blade Maintenance

IMPORTANT: 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 cut indicates blade wear or damage.

⚠ WARNING! An excessively vibrating lawn 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

⚠ WARNING! Wear heavy duty gloves when handling the blade.

IMPORTANT: Only use original replacement parts specified for this lawn mower.

You can purchase a replacement blade (Model MJ40BE-74) and other genuine replacement parts by ordering online at snowjoe.com or, to order by phone, contact Snow Joe ^® + Sun Joe ^® customer service at 1-866-SNOWJOE (1-866-766-9563). The use of parts that do not meet the original equipment specifications may lead to improper performance of the lawn mower, may compromise operator safety, and will void the manufacturer's warranty.

1. Disconnect the electrical supply to the lawn mower and wait until the blade comes to a complete stop.

2. Tum the lawn mower on its side, put a block of wood between the blade and the mower deck to prevent the blade from turning. Loosen the blade nut by a 15 mm wrench or socket (Fig. 16).

3. Remove the blade nut, washer, blade insulator, and the blade (Fig. 17).

Fig. 17 Blade Blade insulation Blade washer Blade nut

Storage

Follow the steps below to prepare the lawn mower for storage:

1. Disconnect the power supply to the lawn mower.
2. Clean the lawn mower with a damp cloth or hand brush.
3. Inspect the lawn mower carefully for worn, loose, or damaged parts. Check connections and screws and tighten if necessary. Pay special attention to the mower blade and replace/sharpen if it shows signs of wear. Refer to the Maintenance section.
4. Store the lawn mower indoors in a dry, clean, and cool area out of the reach of children. Do not store the unit next to corrosive materials, such as fertilizer and rock salt.
5. Wipe the extension cord to remove any foreign substances, such as oil or stains. Replace the extension cord immediately if it is cut or damaged in any way.
6. Wind the cord in a series of equal loops to prevent it from tangling.
7. Do not cover the lawn mower with a solid plastic sheet. Plastic coverings trap moisture around the lawn mower, which can damage the unit.
