This document is the owner's manual for a Greenworks 20" 13 Amp Snow Thrower, model GWSN20130 (2600502). It provides comprehensive instructions for assembly, operation, and maintenance, along with important safety information and a warranty statement.
Function Description
The Greenworks 20" 13 Amp Snow Thrower is an electrically powered device designed for clearing snow from various surfaces. Its primary function is to collect and discharge snow, making it suitable for residential use on driveways, walkways, and other paved areas. The snow thrower is equipped with an impeller that rotates to scoop up snow and propel it through a discharge chute. The direction and height of the snow stream can be adjusted by the operator, allowing for precise control over where the snow is thrown. The device is designed for walking operation, requiring the user to push it across the snow-covered area. It is not intended for use on gravel or crushed rock surfaces due to the risk of throwing foreign objects. The snow thrower operates on a standard 120 V, 60 Hz AC power supply, requiring an extension cord for operation.
Usage Features
The snow thrower incorporates several features to enhance its usability and safety during operation:
- Handlebar Assembly: The device features a multi-part handlebar assembly, including an upper, middle, and lower handle. This design allows for comfortable gripping and control during operation. The handle assembly is secured with bolts and handle knobs, and cam locks are used to secure the upper handle in place.
- Safety Switch Button and Bail Switch: To prevent accidental start-ups, the snow thrower is equipped with a safety switch button and a bail switch. The operator must first press the safety switch button and then simultaneously pull the bail switch towards them to power on the machine. Releasing the bail switch immediately powers off the device. This two-step activation ensures the operator is in a stable position before the impeller begins to rotate.
- Cord Retainer: A cord retainer is integrated into the design to prevent the extension cord from disconnecting from the power cord during use. This feature helps maintain continuous operation and reduces the risk of electrical hazards. The extension cord is looped through the retainer and secured with a retaining clip.
- Adjustable Discharge Chute: The discharge chute can be rotated to direct the snow stream in the desired direction. This adjustment is made by rotating a handle on the chute control rod. This allows the operator to control where the snow is thrown, avoiding obstacles or previously cleared areas.
- Adjustable Chute Deflector: The chute deflector, located at the top of the discharge chute, controls the height of the snow stream. By squeezing a trigger, the operator can raise or lower the deflector, allowing for fine-tuning of the snow discharge trajectory. This is useful for clearing snow over varying distances or avoiding sensitive areas.
- Impeller and Scraper: The snow thrower utilizes an impeller to collect and throw snow. A scraper is positioned at the bottom of the impeller housing, designed to clear snow close to the ground surface.
- Wheels: The device is equipped with wheels for easy maneuverability across snow-covered terrain.
- Carrying/Lifting Handle: A dedicated handle is provided for transporting the snow thrower, making it easier to move when not in operation.
When operating, users are advised to walk, not run, and to be attentive to the terrain, avoiding holes or hidden hazards. It is crucial to keep hands, feet, and clothing away from the discharge chute and impeller openings. The snow thrower should be used in daylight or good artificial light, and safety glasses or goggles, along with ear/hearing protection, are recommended. The manual emphasizes moving up and down slopes rather than across them and exercising caution when changing direction. After clearing snow, it is recommended to let the motor run for a few minutes to prevent moving parts from freezing, then wipe off any ice and snow.
Maintenance Features
The manual outlines several maintenance procedures to ensure the longevity and safe operation of the snow thrower:
- Regular Inspection: Users are instructed to regularly inspect the extension cord and power cord for deterioration, cuts, cracks, or damage to the insulation and connections. Any damaged cords should be repaired or replaced immediately.
- Scraper Replacement: The scraper, located at the bottom of the impeller housing, is a wear item. The manual provides detailed instructions for its replacement, involving the removal of screws from the side plates and the underside of the machine, discarding the old scraper, and installing a new one.
- Drive Belt Replacement: The drive belt is another component that may require replacement due to wear or damage. The manual guides the user through the process of removing the left side cover, detaching the old belt from the impeller and drive pulleys, looping a new belt around the drive pulley, and positioning it on the impeller pulley while rotating the rotor. Finally, the side cover is reinstalled.
- Impeller Replacement: For more extensive repairs, the manual also describes how to replace the impeller. This involves removing screws from the right side cover, detaching the nut, removing the belt, using a socket wrench to remove the large pulley, removing screws from the left side plate, pulling the axle, and then installing the new impeller.
- Cleaning and Storage: After each use, the snow thrower should be cleaned, and any ice and snow wiped off to prevent freezing. Before storage, the motor should be allowed to run for a few minutes to melt any remaining snow. The device should be stored indoors in a dry, locked-up place, out of reach of children. The extension cord should be disconnected and stored with the snow thrower.
- Professional Servicing: For complex repairs or if parts are worn, loose, or damaged, users are advised to contact the toll-free helpline or an authorized service center. Servicing requires extreme care and knowledge, and only identical replacement parts should be used.
The manual stresses the importance of disconnecting the snow thrower from the power supply before performing any maintenance or inspections to prevent accidental start-ups and serious personal injury. It also advises against modifying the product or creating unrecommended accessories, as this could lead to hazardous conditions and void the warranty.
