2. Remove the cap from the fuel tank (Figure 7).

3. Fill the fuel tank with unleaded gasoline to within 6 to 13 mm (1/4 to 1/2 inch) from the top of the tank. Do not fill into the filler neck.

   Important: Do not fill the tank more than 6 mm (1/4 inch) from the top of the tank to allow the gasoline room to expand.

4. Install the fuel-tank cap and wipe up any spilled gasoline (Figure 7).

Important: Running the engine with the air-cleaner cover positioned for cold-weather operation in normal conditions can damage the engine.

The air-cleaner cover has 2 positions: the cold or normal, ambient air positions:

Adjust the air-cleaner cover as follows:

• When operating in a cold ambient air condition (cold air temperature and humidity), position the air-cleaner cover with snowflake decal facing out (Figure 8).

  Note: Use this position if your machine exhibits carburetor icing. Symptoms include the engine runs rough at idle or low speed, and it discharges black or white smoke in the exhaust.

• When operating in a normal ambient air condition, position the air-cleaner cover with sun decal facing out (Figure 8).

  Note: Use this position if your machine is not exhibiting carburetor icing.

   4. Engine switch (ON position)

2. On the rear, left side of the engine, move the choke lever to the ON position. On a warm engine, leave the choke lever in the OFF position (Figure 9).

3. Place the throttle midway between the SLOW and FAST positions located on rear, right side of the engine (Figure 10).

4. Slowly pull the engine-recoil handle until you feel resistance and then stop (Figure 10).

   Note: Allow the recoil handle to return and then sharply pull it straight out.

   Note: Allow the rope to return slowly.

5. Allow the engine to warm up for several minutes, then move the choke lever toward the OFF position (Figure 9).

1. Release the broom-drive lever and the traction-drive lever.

2. Place the throttle midway between the SLOW and FAST positions (Figure 10).

3. Allow the engine to run for a minimum of 15 seconds, then turn the engine On/Off switch to the OFF position to shut off the engine (Figure 10).

4. Wait for all moving parts to stop before leaving the operating position.

5. Use the fuel-shutoff valve to shut off the flow of fuel when you will not use the machine for a few days, park the machine inside a building, or transport the machine to and from the job site (Figure 9).

1. Place the speed selector lever to the desired forward position, making sure that it locks in the notch (Figure 11).

   

   Figure 11

   Note: If the ground speed is too fast, debris or snow will pile up in front of the broom causing the broom to bulldoze instead of sweep. This can damage the bristles and the drive line.

2. Slowly squeeze the left traction-drive lever to the handle (Figure 12).

   Note: Holding down the traction-drive lever against the handle engages the traction drive to both wheels.

   

   Figure 12

3. To stop the traction drive, release the traction-drive lever.

4. To move forward, engage the traction drive and slowly squeeze the left hand traction lever to the handle (Figure 13).

   Note: Momentarily squeezing and releasing the left or right wheel-clutch lever allows for steering adjustments to keep the machine going in a straight line, especially in deep snow.

   Note: To turn right, lift up on the right wheel-clutch lever and squeeze it toward the handle. This disengages the drive to the right wheel, while the left wheel continues driving, and the machine turns to the right.

   

   Figure 13

   Note: Similarly, squeezing the left wheel-clutch lever turns the machine to the left.

   Note: When you complete the turn, release the wheel-clutch lever. The drive engages both wheels (Figure 14).

   

   Figure 14

5. To stop the traction drive, release the traction-drive lever.

1. Place the speed-selector lever into the desired reverse-speed range, making sure that the speed selector locks in the notch.

2. To move rearward, engage the traction drive and slowly squeeze the left traction lever to the handle.

   Note: Momentarily squeezing and releasing the left or right wheel-clutch lever allows for steering adjustments to keep the machine going in a straight line.

   Note: To turn right, squeeze the right wheel-clutch lever toward the handle. This disengages the drive to the right wheel while the left wheel continues driving, and the machine turns to the right.

   Note: Similarly, squeezing the left wheel-clutch lever turns the machine to the left.

Note: Squeezing both wheel-clutch levers simultaneously disengages the drive to both wheels. This enables you to move the machine rearward without stopping to shift it into a reverse gear. It also allows you to maneuver and transport the machine more easily when the engine is not running.

Perform the following before transporting the machine:

• Ensure that the fuel-shutoff valve is closed.

• Place the machine in either a forward or reverse gear, then block the wheels.

• Securely fasten the machine to the trailer with straps, chains, cables, or ropes.
