Section 5: Maintenance 19

WARNING

Before inspecting, cleaning or servicing the machine, shut off engine, wait for all moving parts to come to a complete stop, remove ignition key on electric start models, disconnect spark plug wire and move wire away from spark plug.

Failure to follow these instructions can result in serious personal injury or property damage.

CHECKING AND ADJUSTING TENSION ON CLUTCH BELTS

WARNING

Follow the belt adjustment instructions carefully. An incorrect adjustment could result in the clutch control mechanism engaging too soon. This could cause loss of tiller control and result in per- sonal injury or property damage.

Maintaining correct belt tension is impor- tant to good tilling performance and long belt life. A loose belt will slip on the engine and transmission pulleys and cause the tines and wheels to slow down

or stop – even though the engine is running at full speed. A loose belt will also result in premature belt wear.

While checking belt tension, also check for cracks, cuts or frayed edges. A belt in poor condition should be replaced.

NOTE: The photographs in this Section show a reverse drive assembly (pulley (A, Figure 5-8), belt (B), cable (C) and linkage(D)). These components are not used on Model 12226.

Checking and Adjusting

Forward Clutch Belt Tension

It is important to maintain correct tension on the forward clutch belt (C, Figure 5-9). A loose belt will cause the tines and wheels to slow down – or stop completely

even though the engine is running at full speed. A loose belt will also result in pre- mature belt wear.

Check belt tension after the first two hours of break-in operation and after every 10 operating hours.

At the end of each tilling season, check the belt for cracks, cuts or frayed edges. A belt in poor condition should be replaced.

2-1/2" extended spring length

Figure 5-10: Correct spring length when Forward Clutch Levers are engaged is 2-1/2".

Checking Forward Belt Tension

1.Before checking, shut off engine, allow the engine and muffler to cool down, dis- connect the spark plug wire, remove the ignition key on electric start models.

2.The coiled part of the forward clutch spring (E, Figure 5-9) measures 2" in length when the Forward Clutch Control levers are not pulled up. Pull either Forward Clutch Control Lever up against the handlebar and measure the length of the coiled part of the forward clutch spring. Tension is correct if the length of the extended coil is 2-1/2" (see Figure

5-10). The forward clutch cable needs adjustment if length of the extended coils is less than 2-1/2". See Adjusting the Forward Clutch Belt for a procedure. If the extended length is more than 2-1/2", there is no need to adjust as long as the unit operates correctly when moving Forward.

Adjusting the Forward Clutch Cable

Do this procedure if the forward clutch spring measurement is not correct (see Checking Forward Belt Tension)

1.Before adjusting the belt, shut off

engine, allow the engine and muffler to cool down, disconnect the spark plug wire, and remove the ignition key on elec- tric start models.

12226 specifications

The Bolens 12226 is a powerful and versatile two-stage snowblower designed to tackle heavy snowfall and icy conditions with ease. It stands out in the market for its robust construction and innovative technologies, making it an essential tool for homeowners living in regions prone to harsh winter weather.

At the heart of the Bolens 12226 is its reliable 208cc PowerMore engine, engineered for maximum performance and durability. The engine's 4-cycle design ensures efficient fuel use while providing ample torque to handle the toughest of snow. This snowblower features a 26-inch clearing width, allowing it to clear large swathes of snow in a single pass, significantly reducing the time spent on snow removal.

One of the standout characteristics of the Bolens 12226 is its two-stage snow clearing system. In the first stage, the auger collects snow and ice, which is then propelled into the second stage, where an impeller throws the snow out of the chute. This efficient design is ideal for tackling heavy, compacted snow and can easily handle drifts and deeper accumulations.

The snowblower's adjustable chute can rotate up to 200 degrees, allowing the user to direct the snow exactly where they want it to go. The built-in deflector provides further customization, enabling operators to control the height of the discharge, whether they’re clearing a driveway or a sidewalk. This flexibility ensures that users can adapt to various snow conditions and landscapes.

For ease of operation, the Bolens 12226 includes a self-propelled feature with six forward speeds and two reverse speeds, offering comfortable maneuverability across diverse terrains. The large, deep-tread tires enhance traction, providing stability and control even on icy surfaces.

Safety and convenience are key features as well; the snowblower comes equipped with an electric start for hassle-free ignition, eliminating the need for strenuous pull starts in cold weather. Additionally, the ergonomic control panel allows for easy operation, ensuring that users have a comfortable experience while tackling winter challenges.

In summary, the Bolens 12226 is a well-engineered snowblower that merges power and ease of use. With its robust engine, efficient two-stage clearing system, adjustable chute, and user-friendly features, it is an invaluable tool for anyone needing to maintain a clear and safe outdoor space during snowy months. Its thoughtful design and reliable performance make it a standout choice for winter weather preparedness.
