STARTING CONTROLS

Units with Optional Electric Start

A. Electric Start Button - The Electric Start Button

(A, Figures 4 & 5) activates an electric starter mounted to the engine, eliminating the need to pull the starter handle. The Electric Start Button operates on 120 Volts AC, which is provided by connection to the extension cord provided with units equipped with this feature.

Connect this extension cord ONLY to a

properly grounded 3 prong electrical outlet.

Manual Start

B. Fuel Valve - The fuel valve (B, Figure 4 & 5) is locat-

ed under the fuel tank. It is used to turn the fuel supply off for out-of-season storage.

C. Starter Handle - The starter handle (C, Figure 4 & 5)

connects to a starter cord to manually start the engine. Pulling starter handle rapidly spins the engine crankshaft, cycles the engine, and generates the spark necessary for starting the engine.

D. Primer Button - When pressed, the primer button

(D, Figure 4 & 5) provides initial fuel to help start a cold engine. Normally, pressing the primer button twice will provide enough fuel to start a cold engine.

E. Throttle Lever - The throttle lever (E, Figure 4 & 5)

controls the engine speed. For best overall performance, the throttle lever should be set to the FAST position. Use the SLOW position only for warming the engine, or to help prevent snow/ice freeze-up when shutting the unit down for the day.

F. Engine Key - The Engine Key (F, Figure 4 & 5) pre-

vents the engine from being started by unauthorized individuals. The key must be fully inserted into the key slot for the unit to start. The key is also used to stop the engine by pulling the key out of the key slot.

G. Choke Knob - The Choke Knob (G, Figure 4 & 5)

adjusts the air/fuel mixture, and is used to help start a cold engine by providing a richer mixture. Once the engine is warm and running smoothly, the Choke Knob should be set to the off position to provide a normal air/fuel mix.

GROUND SPEED CONTROLS

A. Speed Selector - This lever (A, Figures 6 & 7) is

used to set the ground speed of the snowthrower. The snowthrower has five forward speeds, 1–5, and

two reverse speeds, 1–2. No neutral position or gate is required, since the traction drive design automatically provides "neutral" (no forward or reverse movement), whenever the Drive Control is released.

B. Drive Control - This control engages the traction

drive as the lever (B, Figures 6 & 7) is depressed, and disengages the traction drive when the lever is released. The traction drive provides power to the wheels. NOTE: Changing ground speeds must only be done while the Drive Control is in the disengaged (fully released) position.

AUGER CONTROL

C. Auger Control - The Auger Control clutch lever (C

Figures 6 & 7), engages the auger drive (which throws the snow) as the lever is depressed, and disengages the auger drive when the lever is released.

DEFLECTOR CONTROLS

D. Chute Direction Control - The Chute Direction

Control (D, Figures 6 & 7), allows the discharge chute to be rotated to throw snow in the desired direction. Snow may be thrown at any angle from straight left, to straight forward, to straight right.

E. Chute Deflector - Controls the distance snow is

thrown. Tilting the Chute Deflector (E, Figures 6 & 7) UP provides a higher stream and greater distance, while tilting the deflector DOWN provides a lower stream and less distance.

F. Chute Deflector Knob - This knob (F, Figures 6 & 7)

allows the discharge Chute Deflector (E, Figures 6 &

7) to be locked in the desired tilt position.

SCRAPER HEIGHT CONTROL

G. Scraper Bar Height Control - The Skid Shoes (G,

Figure 7) control the height the scraper bar (located at the bottom of the auger housing). The scraper bar allows smooth surfaces (such as concrete or asphalt driveways) to be scraped clean of snow. On surfaces such as gravel, the scraper bar should be adjusted higher — so that it will not pick up gravel or debris.

TRACTION LOCK CONTROL

H. Traction Lock Pins - The traction drive to each

wheel can be locked and unlocked with the Traction Lock Pins (H, Figure 7) to permit the unit to “freewheel,” allowing easier manual handling and transport of the snowthrower.

GENERAL OPERATION

CHECKS BEFORE EACH START-UP

1. Make sure all safety guards are in place and all nuts, bolts and clips are secure.

2. Check the engine oil level. See your engine Owner’s Manual for procedure and specifications.

3. Check to make sure spark plug wire is attached and spark plug is tightened securely. If necessary, torque spark plug to 15 ft. lbs.

4. Check the fuel supply. Fill the tank no closer than 1/4 to 1/2 inch of top of tank to provide space for expansion. See your engine Owner’s Manual for fuel recommendations.

5. Check the Scraper Bar to make sure it is set at the desired height. Adjust the Skid Shoes if necessary. (See page 11.)

6. Check the Drive Control (B, Figure 6), and Auger Control (C, Figure 6) for proper operation. If adjustment is required, see the Service section for procedures.

7. Check the Chute Direction Control (D, Figure 6) for proper operation. The discharge chute should rotate freely in both directions. See the Service section for adjustment procedures and troubleshooting.

8. Check the Chute Deflector (E, Figure 7) for proper operation. The deflector should pivot freely up and down when the Chute Deflector Knob is loosened. If adjustment is required, see the Service Section for procedures.

9. Position the chute at the desired starting direction and set the deflector at the desired angle.

10.Check the Speed Selector (A, Figure 6) for smooth operation. The control must move freely into each speed position gate and remain in position when released. If the Speed Selector does not move freely into all forward and reverse speed positions, contact your local authorized dealer for assistance.

Operation

WARNING

To avoid serious injury, do not put your hands into the auger housing or discharge chute. If auger stalls or chute becomes plugged, use the following procedure to remove objects or clear the chute:

WARNING

For your safety, operation on slopes should be in an up and down direction only. If it becomes necessary to move across the face of a slope, use caution and do not blow snow. Be very careful when changing direction on a slope.

Proper winter footwear is recommended for the operator to help prevent slipping. Never attempt to clean snow from excessively steep slopes. The maximum slope for any operation is 17.7% (10º).

WARNING

Gasoline is highly flammable and must be handled with care. Never fill the tank when the engine is hot or running. Always move outdoors to fill the tank. Keep snowthrower and gasoline away from open flame or spark.

1. Release both the Drive and Auger Control levers.

2. Shut off the engine.

3. Remove the Engine Key.

Figure 15. Traction Drive Lock - Engaged

AFTER EACH USE

Normal use of the snowthrower may result in a build-up of packed snow in and around the starter cord housing and around engine controls.

Heat from the engine will usually prevent the snow from freezing solid while the unit is running, but after the engine is shut down, some snow may continue melting from engine heat, and later freeze around some moving parts as the unit cools.

After each period of use, follow these steps

to prevent

freeze-up caused by ice formation

in and around the

engine controls and external parts.

1. Before shutting off the engine, pull the starter rope out 2 - 3 times, and allow it to rewind slowly. This will help clear packed snow from the starter cord area.

2. Stop the engine by moving the Throttle Lever (See Figure 11) down, or by pulling out the Engine Key.

3. Disconnect the spark plug wire, and position it away from the spark plug.

4. Brush snow and ice from the snowthrower. Be sure to clear engine and snowthrower controls, discharge chute, worm and chute rod gears, clutch rod areas, and anywhere else snow has accumulated.

5. Always remove the Engine Key and store in a safe place to prevent unauthorized use.

6. If the snowthrower is kept in a cold shelter, fill the fuel tank to prevent condensation. Do not store near sparks or flame.

Note: The Engine Owner’s Manual contains further information on preventing ice formation and freeze-up.

OFF-SEASON STORAGE

Before you store your snowthrower for the off-season, read the Maintenance and Storage instructions in the Safety Rules section and take the following precautions:

NOTE: Gasoline, if permitted to stand unused for extended periods (30 days or longer), may develop gummy deposits which can adversely affect the engine carburetor and cause engine malfunction. To avoid this condition, add Simplicity Gasoline Stabilizer to the fuel tank, or drain all fuel from the system before placing unit in storage.

1. Prepare your snowthrower engine for storage as instructed in the Engine Owner’s Manual.

2. Lubricate the snowthrower as described in the LUBRICATION section of this manual.

3. Clean the snowthrower thoroughly. Coat exposed bare metal parts with a quality paint (available from you dealer) or a light film of grease, oil or automotive wax.

4. Store snowthrower in the wheels down, operating position.

Note: If the unit is stored in any other position, oil from crankcase could enter cylinder head, causing a service problem.

5. Store the unit in a protected area and cover.

STARTING AFTER STORAGE

1. Remove the spark plug and wipe dry. Crank the engine a few times to blow excess oil out of plug hole. Then reinstall plug.

2. Fill fuel tank with fresh gasoline (unless a fuel stabilizer was used).

3. Check to be sure engine fins are clean and air flow is unobstructed.

4. Check engine oil level and lubricate snowthrower. Change oil if necessary.

5. Start the engine outdoors. Warm up engine by running at SLOW speed for a a few minutes before running at FAST speed, or blowing snow.

6. Check the operation of all the controls. If necessary, lubricate the snowthrower to improve operation of the chute control.

CHECK AUGER GEAR CASE LUBRICATION

1. Place the snowthrower on a level surface.

2. Remove the Pipe Plug (Figure 16).

3. Check the lubricant level. It should be level with the lower edge of the plug opening. If not, add Simplicity Winter Weight Worm Gear Oil (available from your dealer).

4. Re-install Pipe Plug, and tighten securely.

Figure 16. Checking Auger Gear Case Lubrication

Pipe Plug

Regular Maintenance

There are two grease fittings on the auger shaft (Figure

18). Wipe the fittings clean and apply grease, using a grease gun. Also apply grease on other points indicated.

Apply medium weight (10W) oil to points shown(See Figures 17 - 19).

Generally, all moving metal parts should be oiled where contact is made with other parts. Keep oil and grease off belts, pulley grooves, drive disc, and friction disc.

See lubrication notes at bottom of page.

IMPORTANT NOTE

It is very important that grease fittings on the auger shaft are lubricated regularly. If auger rusts to shaft, damage to worm gear may occur if shear pins do not break.

To prevent wheels rusting to axles, it is also necessary to remove the wheels and grease the axles regularly.

TRACTION DRIVE CLUTCH ROD ADJUSTMENT

Initial Adjustment

The traction drive clutch rod should initially be adjusted so that there is no slack in the rod when moved slightly from side to side, but bellcrank arm remains in fully down position. To adjust tension on the rod:

1. Loosen adjustment hex nuts (Figure 21).

2. Tighten top hex nut while holding rod. Tighten just

until slack in rod is removed.

3. Tighten lower hex nut securely.

Figure 21. Traction Drive Clutch Rod Adjustment

Traction Drive Clutch Rod

Adjustment Hex Nuts

Traction Drive Bellcrank Arm

Run-In Adjustment

1. After 5 hours of use, check for proper adjustment. Readjust clutch rod if necessary by increasing tension on rod. A small amount of bellcrank arm movement is permissible if unit passes operating checks described in the Caution at left. Optimal adjustment

provides 1/32" clearance between traction drive disc and rubber ring on friction disc when drive lever is released (see Figure 17).

WARNING

Do not over-tighten, as this may cause traction drive to engage without depressing the traction Drive Control (bellcrank arm must remain in down position).

Verify that the rods are not over-tightened: With Speed Selector in position 1 and traction Drive Control fully released, push snowthrower forward. The unit should move forward freely.

If unit does not move forward freely, the rod has been over-tightened. To remedy, loosen tension on clutch rod slightly, and recheck.

2. Tighten top hex nut while holding rod. Tighten just until slack in rod is removed. Be careful not to move idler rod lever when adjusting clutch rod tension.

3. Tighten lower hex nut securely.

4. Start unit and check auger. Auger must not be engaged unless Auger Control is depressed.

5. With engine running, fully depress Auger Control, the auger should engage and run normally.

6. Release Auger Control. Auger must stop within 5

seconds.

7. If auger does not operate properly, stop engine and recheck clutch rod adjustments.

8. If clutch rod is properly adjusted, auger drive belt tension may require adjustment. See "Adjusting Auger Drive Belt" on next page.

Figure 23. Drive Belt Paths

DRIVE BELT ADJUSTMENT

The snowthrower is equipped with two drive belts located just in front of the engine under the belt cover. Figure 23 shows both belts and idler pulleys. The belt nearest the engine is the unit traction drive (wheels) belt. The belt farthest from the engine is the auger/ impeller drive belt.

The traction drive belt has constant tension provided by a spring-loaded idler pulley arm, and is non-adjustable. This belt rotates whenever the engine is running, and provides power to the traction drive disc, which also rotates constantly while the engine is running.

The auger drive belt tension may be adjusted by moving the auger drive idler pulley. See "Adjusting Auger Drive Belt’ on next page.

DRIVE BELT ADJUSTMENT (Continued)

If the auger drive slips (auger slows or doesn't rotate normally while blowing snow), or stays engaged when the control is disengaged — and the auger clutch rod has been properly adjusted — the auger drive belt may be out of adjustment.

Checking Auger Belt & Belt Guide Adjustments

1. Insert the Engine Key and start the Snowthrower.

2. Engage and disengage the Auger Control a series of ten times, checking that the auger comes to a complete stop within 5 seconds after the control is disengaged each time.

3. If the auger comes to a complete stop each time within 5 seconds, the adjustment is correct. If the auger does NOT come to a complete stop within the necessary 5 seconds, the adjustment is incorrect: readjusting the Auger Belt & Belt Guide according to the procedures below.

Adjusting Auger Drive Belt

1. Make certain that the snowthrower is off, the Engine Key has been removed, and the spark plug disconnected.

2. Check that there is no slack in the auger drive clutch rod (see Figure 25). If there is, follow the Auger Drive Clutch Rod Adjustment procedure on page 19.

3. Measure the length of the auger drive clutch spring (Figure 25).

4. Fully depress the auger control and measure the expanded length of the spring.

The spring should expand 19/64”-5/16”. If the spring deflection is less than 19/64”-5/16” the auger idler pulley must be adjusted. Proceed to step 5.

5. Using a 3/8” wrench, loosen the Belt Cover screws and remove the Belt Cover.

6. Loosen the adjustment bolt (see Figure 26) and move the auger idler pulley.

7. Tighten the adjustment bolt and repeat steps 3-4.

8. Test run the unit. The auger must NOT rotate unless the Auger Control lever has been depressed. Proper Auger Drive Belt adjustments stop the auger within 5 seconds after the Auger Control is disengaged. If the auger drive fails either of these tests, repeat the adjustment procedures.

DRIVE BELT ADJUSTMENT (Continued)

Adjusting Auger Belt Guide

1. With the Auger Control still fully depressed, adjust the Auger Belt Guide so that there is a 1/64” gap (1/32” Maximum) between the end of the guide and the belt (Figure 27), making certain the guide is NOT putting pressure on the belt.

2. Making certain the Auger Belt Guide does NOT move while doing so, tighten the Auger Belt Guide Screw (Figure 27) to secure the guide.

3. Check the adjustment on the Auger Belt Guide (Figure 27) to make certain that the gap between the belt and the belt guide is correct.

4. Disengage the Auger Control by removing the cardboard tube (or other means used to temporarily secure the control.)

5. Test the unit by following the steps under the “Checking Auger Belt & Belt Guide Adjustments” above.
