Safety • This snowthrower meets or exceeds the ISO standard 8437 in effect at the time of production. Operation Before use, check the supply and extension cord for signs of damage or aging. Read and understand the contents of this manual before the engine is ever started. • Do not put hands or feet near or under rotating parts. Keep clear of the discharge opening at all times. This is the safety alert symbol. It is used to alert you to potential personal injury hazards.
• Never direct the discharge at bystanders or allow anyone in front of the unit. Sound Pressure • Never operate the snowthrower without good visibility or light. Always be sure of your footing, and keep a firm hold on the handle. Walk; never run. This unit has a maximum sound pressure level at the operator ’s ear of 89 dBA, based on measurements of identical machines per Directive 98/37/EC.
Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost. 107-3040 1. Cutting dismemberment, impeller and cutting dismemberment, auger hazards—keep bystanders a safe distance from the snowthrower. 107-3324 1.

Setup 6. Place the mounting plate over the tubes (Fig. 3). Note: Determine the left and right hand sides of the snowthrower by standing in the normal operating position. 2 4 1 3 Installing the Upper Handle and Chute Crank 1. Stand the snowthrower on its wheels and position the upper handle. 1532 2. Inspect the open internal wiring; if it is damaged, do not assemble. Contact an Authorized Service Dealer. Figure 3 1. Mounting plate 2.
Before Starting Installing the Discharge Chute 1. Position the chute deflector onto the discharge chute and align the mounting holes (Fig. 5). For safe and efficient use of your appliance, use only an extension cord recommended for outdoor use. Use only a 2.5 mm2 extension cord up to 25 m long. 1 Warning 5 Contact with water while operating the snowthrower can cause electric shock, resulting in personal injury or death.
Operation • To adjust the discharge chute, rotate the chute crank clockwise to move the discharge chute to the left; counterclockwise to move it to the right. Check the condition of the snowthrower before operating it to ensure that the rotor turns freely. Note: The chute crank makes a noise as you turn the crank. This is normal. To adjust the height of the snow stream, raise or lower the chute deflector handle (Fig. 8). Starting and Stopping 1. To start the rotor, squeeze the control bar (Fig. 7).
• When operating the snowthrower, keep the wheels 1 inch (2.5 cm) off the pavement by tipping the snowthrower forward. This helps prevent the snow from building up on the wheels. • To shave down large banks of snow, lift the snowthrower by the primary and secondary handles (Fig. 9) and place the snowthrower on the bank. Let the weight of the snowthrower shave down the bank in a back-and-forth motion. • After clearing the snow, let the motor run for a few minutes so that moving parts don’t freeze.
Replacing the Scraper 2. Use a 5/16-inch Allen wrench to turn the rotor shaft clockwise (left-hand thread) while holding the rotor (Fig. 12). The scraper is located at the bottom of the rotor housing as shown in Figure 10. 2 1 2 2 1 Figure 12 1517 1. Rotor shaft Figure 10 1. Scraper 1538 2. Screw 2. Rotor Note: You may need to tap the Allen wrench with a hammer to loosen the rotor shaft. Wedge a stick or a hammer handle in the rotor to prevent it from rotating. 1.
6. Align the left side of the new rotor with the coupler. 3. Remove the idler spring from the idler arm (Fig. 16). Note: The 3 bosses on the rotor end must align with the slots on the coupler (Fig. 15). 1 1 2 4 1526 Figure 16 1. Idler spring 3 2 1518 4.

7. Slide 2 washers onto the bolt and insert the bolt through the small pulley. 7. Rotate the rotor with your left hand while sliding the belt onto the large pulley with your right hand (Fig. 19). Note: The bolt must ride on bearings in the small pulley. 8. Place the new belt on the small pulley. 9. Slide the belt over the motor shaft pulley (Fig. 20). 10. Torque the bolt to 25 to 30 in-lb (2.8 to 3.4 N⋅m). Do not overtighten the bolt.
