1800 Power Curve® Snowthrower

• Check all fasteners at frequent intervals for proper tightness to ensure that the appliance is in safe working condition.

• Always refer to the Operator’s Manual for important details if the appliance is to be stored for an extended period.

• Maintain or replace safety and instruction labels as needed.

• Run the appliance for a few minutes after throwing snow to prevent freeze-up of the rotor blades.

1. Remove the handle knobs, oval bolts, and curved washers from the lower handle.

2. Install the upper handle to the lower handle of the machine with the handle knobs, curved washers, and oval bolts as shown in Figure 1.

   Note: Ensure that the power cord attached to the machine is routed over the lower handle and to the inside of the handle assembly.

3. Tighten the handle knobs firmly by hand.

4. Attach the cord guide to the handle (Figure 2).

1. Position the discharge chute so that it faces forward.

   Important: Align the arrow on the discharge chute with the arrow on the housing (Figure 3).

5. Firmly push the rod into the keyed hole in the back of the housing until it snaps into place.

6. Move the handle on the chute control rod to ensure that it moves in the same direction as the chute (Figure 7).

Important: This machine is intended for outdoor, residential use only. Do not use it indoors or for commercial or industrial purposes.

To reduce the risk of electric shock, this machine has a polarized plug (i.e., one blade is wider than the other). Use only a polarized plug, UL-listed (CSA certified in Canada) extension cord recommended for outdoor use. A polarized plug will fit in a polarized cord only one way. If the plug does not fit fully in the cord, reverse the cord. If it still does not fit, purchase a polarized extension cord. If you have a polarized extension cord and the extension cord plug does not fit fully into the wall receptacle, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the machine or extension cord plug in any way.

Note: Do not use an extension cord over 48 meters (150 feet).

Important: Check the extension cord frequently during use for holes or cracks in the insulation. Do not use a damaged cord. Do not run the cord through standing water.

Note: To prevent the extension cord from disconnecting during operation, use the cord lock on the upper handle before you connect it to the machine (Figure 9).

1. To start the motor, insert the interlock button (key), press and hold the interlock button (key), and squeeze the power control bar to the handle (Figure 10).

   2. Power control bar

   Note: You may release the interlock button (key) after you squeeze and hold the power control bar to the handle.

2. To stop the motor, release the power control bar.

   Note: When you stop the machine after you have finished removing the snow, also remove the interlock button (key) and disconnect the extension cord.

To adjust the discharge chute, move the handle on the chute control rod in the direction that you wish to direct the snow stream (Figure 6 and Figure 7).

To adjust the chute deflector (and therefore the height of the snow stream), squeeze the trigger and raise or lower the chute deflector (Figure 11).

• Check the condition of the machine before operating it to ensure that the rotor turns freely.

• Always keep children and pets away from the area of operation.

• Keep the area to be cleared free of stones, toys, or other objects which the rotor blades can throw. Such items could be covered by snowfall and go unnoticed. If the machine strikes an object during operation, stop the machine, unplug the extension cord, remove the obstruction, and check the machine for damage.

• Begin removing snow near the electrical outlet and work outward. Blow back and forth, not away from and toward the outlet.

• When turning at the end of a swath, step over the cord and turn the machine.

• Always overlap each swath and discharge the snow downwind when possible.

  Warning

  When using the discharge chute handle, never direct the snow discharge chute at the operator or bystanders. The machine can throw objects and cause serious personal injury.

  When using the discharge chute handle, always turn the discharge chute in the opposite direction from where you or bystanders are standing.

• Keep the extension cord clear of obstructions, sharp objects, and all moving parts. Do not pull sharply on cord or abuse it in any manner. Inspect the extension cord frequently for damage that may result in an electric shock. If the extension cord is damaged, replace it.

• In cold and snowy weather conditions, some controls and moving parts may freeze. Therefore, if any control becomes difficult to operate, stop the motor, disconnect the extension cord, and check for frozen parts. Do not use excessive force when trying to operate frozen controls. Bring the machine indoors to thaw frozen controls before operating it.

• When operating the machine, keep the wheels 2.5 cm (1 inch) off the pavement by tipping the machine forward. This helps prevent the snow from building up on the wheels.

• After clearing the snow, let the motor run for a few minutes so that moving parts do not freeze. Then shut off the motor, wait for all moving parts to stop, and wipe the ice and snow off the machine. Rotate the chute crank several times to remove any snow.

You do not need to lubricate the machine; all the bearings have been lubricated at the factory for the life of the machine.

The scraper is located at the bottom of the rotor housing as shown in Figure 12.

   Note: Ensure that the nut that secures the rotor pin remains inside the recessed hole in the right inside wall of the housing.

   Note: The housing will flex when you install the rotor.

5. Tighten the bolt on the side of the housing.

6. Install the right side plate with the screws that you removed in step 1.
