Operation

PRE-OPERATION CHECKLIST

Perform the following checks with the engine stopped and the spark plug wire disconnected from the spark plug.

1.Review Section 1: Safety and Section 3: Features and Controls in this manual.

2.Check for loose or missing hardware. Tighten or replace as needed.

3.Visually check inside the collector (auger/impeller) housing and the dis- charge chute and remove any debris.

CAUTION

Do not start engine until engine crankcase has been filled with oil. Failure to follow this instruction will re- sult in serious engine damage.

4.With the unit on level ground, check the engine oil level according to the in- structions in the engine manual. The oil level should be at the “FULL” mark on the dipstick.

DANGER

GASOLINE IS HIGHLY FLAMMABLE AND ITS VAPORS ARE EXPLOSIVE.

•Follow the gasoline safety rules in this manual (Section 1) and in the separate Engine Owner’s Manual.

•Failure to follow gasoline safety in- structions can result in serious per- sonal injury and property damage.

5.Turn off engine and let it cool for at least 2 minutes before removing the gasoline fill cap. Remove the fill cap and check the level of gasoline in the fuel tank according to the instructions in the engine manual.

Use fresh, clean, unleaded gasoline (refer to engine manual for additional gasoline information). Do not overfill fuel tank. Fill to approximately 1-1/2 inches below top of neck to allow for fuel expansion. DO NOT MIX OIL WITH GASOLINE! Tighten the gasoline fill cap securely.

6.The unit should be adjusted so the col- lector (auger/impeller) housing and

the scraper blade (A, Figure 4-1) are 1/8" above the surface to be cleared. If clearing gravel or uneven surfaces, in- crease the clearance so gravel or other foreign objects are not scooped up into the auger.

To adjust the collector housing height/scraper blade height:

a. Move the unit onto a level surface. b. Loosen the four screws securing the

two skid shoes (B, Figure 4-1).

c. Adjust the skid shoes (B) until they are in the correct position to support the collector (auger/impeller) hous- ing and the scraper blade (adjust skid shoes equally to prevent uneven snow removal).

d. Tighten the four screws.

e. The scraper blade (A, Figure 4-1) can also be adjusted. Adjust the scraper blade at the four carriage bolts (C, Figure 4-1). Adjust the bot- tom edge of the scraper blade so it is parallel to the bottom edge of the auger.

7.Use the lever on the Discharge Chute Deflector Cap (D, Figure 4-3) to adjust the deflector cap to the desired angle of discharge. Usually keep the angle of the deflector cap low, especially in windy conditions.

8.Rotate the Discharge Chute Control Rod (E, Figure 4-3) and check for binding. Leave the discharge chute pointing straight ahead.

9.Check the Auger Drive and Wheel Drive control levers (F and G, Figure 4- 3) for freedom of movement.

10.Check the tire pressure. Inflate both tires evenly to 8 to 12 PSI (55 to 82 Kpa).

11.Apply silicone spray on the inside of the discharge chute, the chute dis- charge deflector cap, the collector (auger/impeller) housing, and on the augers. This will help prevent snow from sticking (do not allow silicone spray on rubber or plastic: damage can result).

12.Reconnect the spark plug wire (see engine manual) to the spark plug.

STARTING THE ENGINE

1.Complete the Pre-Operation Checklist. Read the engine manual before start- ing the engine.

2.Move the unit outside to a well-venti- lated, level area. Put the Gear Shift Lever (H, Figure 4-3) into the desired gear position. Use the slowest (1) forward and reverse (R1) speed set- ting when first using the unit.

3.Rotate the Fuel Shut-Off Valve (J, Figure 4-2) 1/4 turn counterclockwise to the ON (open) position.

4.Move the Throttle Lever (L, Figure 4-2)

to the FAST position.

5.Insert the Stop Switch Key (K, Figure 4-2) all the way into the switch. (The key was included in the hardware bag with other loose parts.)

6.Turn Choke Knob (M, Figure 4-2) to CHOKE setting (a warm engine may not require choking when restarting).
