SECTION 2: ASSEMBLING YOUR SNOW THROWER

NOTE: Any reference in this manual to the left or right side of the snow thrower is observed from the operator’s position.

Unpacking

•Remove screws from the top sides and ends of the shipping crate.

•Set panel aside to avoid tire punctures or personal injury.

•Remove and discard plastic bag that covers unit.

•Remove any loose parts included with unit (i.e., Operator’s Manual, etc).

•Roll unit out of crate.

Loose Parts

The augers are secured to the auger shaft with two shear bolts and hex lock nuts. If you hit a foreign object or ice jam, the snow thrower is designed so that the bolts may shear. Two replacement shear bolts and nuts are provided for your convenience. Store in a safe place until needed. See Figure 1.

•Raise the upper handle assembly until it locks over the lower handle.

•Look at the lower rear of the snow thrower frame to be sure all the cables are aligned with the cable roller guides.

•Secure the upper handle and lower handle with the two plastic wing nuts, cupped washers and carriage bolts previously removed and tighten the upper two plastic wing nuts. See Figure 3.

•Slide the shift rod connector down over the end of the lower shift rod. Tap the connector until it locks over the lower shift rod. See Figure 3.

NOTE: If the connector is not properly assembled, the shift rod will pivot and you will not be able to change speeds or change directions.

•If not already attached, slip the cables that run from the handle panel to the chute into the cable guide located on top of the engine. See Figure 4.

•Unwrap the headlight wire, which is attached to the headlight beneath the handle panel.

•Wind the headlight wire around the right handle until excess slack is removed.

•Plug the wire from the headlight into the wire lead coming from the right side of the engine, beneath the fuel tank.

Low Rds(on) translates to lower conduction losses during operation, leading to reduced heat generation. This characteristic is crucial in applications where thermal management is a concern, allowing designers to minimize the size of heat sinks and cooling systems.

The MTD 31AH5C3F401 complements this with a fast switching speed, which is essential for high-frequency applications such as switch-mode power supplies (SMPS) and DC-DC converters. The rapid transition from on to off state results in decreased switching losses, allowing for higher overall efficiency in power conversion processes.

Both models utilize a robust silicon technology that enhances their reliability and durability under various operational conditions. Their maximum voltage ratings can easily accommodate voltage transients encountered in automotive applications, ensuring they can handle high-stress environments without compromising performance.

In terms of packaging, the MTD 31AH5Q3G401 and 31AH5C3F401 are available in compact forms, enabling designers to save space on PCBs while maintaining a high power density. The integration of thermal management features within the package reduces thermal resistance, further aiding in effective heat dissipation, which is critical in prolonged use.

A common characteristic of both devices is their ability to operate in a wide range of temperatures, which makes them suitable for both outdoor and indoor applications. They are capable of delivering reliable performance across different environmental conditions, enhancing their usability in various sectors.

In summary, the MTD 31AH5Q3G401 and 31AH5C3F401 are exemplary components featuring low on-resistance, fast switching capabilities, robust silicon technology, and compact packaging. These attributes position them as ideal choices for designers looking to enhance the efficiency and reliability of their electronic systems while managing thermal challenges effectively. With their versatility and strong performance metrics, these MOSFETs are set to play a vital role in the future of power electronics.
