2-SPEED SHIFT LEVER

The 2-SPEED SH IFT LEVER (Fig. 7) provides 2 speed

ranges which are selected with lever at rear of chassis. The high speed (H I) is to be used for norma I snow re- moval and low speed (LO) is desirable for use when extremely heavy work is required. Move lever to the

left for "H I" and to the right for "LO". Select "H I" or

"LO" speed prior to shifting control rod to "FORWARD" or "REVERSE" drive. It may be necessary to move snow thrower forward or backward slightly to align

cogs in transmission so that shift lever can be com-

pletely engaged in "HI" or "LO" position.

Before attempting to use your snow thrower, read carefully all the operating instructions below and be sure you understand the function of all controls. Read again the "Rules for Safe Operation" at the front of this manual.

BEFORE STARTING ENGINE

1. Remove oil filler plug and dipstick on L.H. side of engine and check oil level. Fill to "FULL" mark on

dipstick with S.A.E. 5W-30 oil (Fig. 13). Pour slowly to prevent air lock. To check oil level correctly,

screw filler plug and dipstick all the way in. Over- filling the engine may affect performance. Tighten filler plug secur:ely to prevent leakage.

2. Fill fuel tank with any regular grade of fresh, clean gasoline. Lead free gasoline may be substituted.

Do not use Ethyl or High Octane gasoline.

TO START ENGINE

NOTE: All small gasoline engines tend to be difficult to start in cold weather. Since this unit will always be used in cold weather, we recommend you store it

in a heated area.

1. Place primary clutch lever up into disengaged ("OUT") position and place impeller clutch shift rod in disengaged ("OUT") position (Fig. 14 and 15).

2. Move shift control rod to "NEUTRAL" position in "Z" slot of handle plate (Fig. 16).

3. Move throttle control down to "FAST'" position (Fig.

16).

4. Turn choke lever to "FULL" choke position (Fig. 17). Turn ignition switch located on engine shroud to

"ON" position (Fig. 17).

5. IF TEMPERATURE IS BELOW loaF: Depress primer button on carburetor (Fig. 17), 2 or 3 times.

Step #5 may be omitted if temperature is above loaF.

6. Pull engine over rapidly with starter rope.

7. As engine warms up, slowly return choke lever to "OFF" position (Fig. 17).

TO STOP ENGINE Move throttle control up to "STOP" position (Fig. 16).

OPERATING YOUR SNOW THROWER

1. Before starting engine, be sure primary clutch lever is up in disengaged ("OUT") position (Fig. 14), im- peller clutch shift rod is in ("OUT") position (Fig.

15), and shift control rod is in neutral position (Fig.

16).

2. Assume operating position behind unit, and start engine. Using throttle control, adjust to moderate speed.

3. Squeeze safety lever up into operating position against R.H. handle with right hand, and maintain hold on lever and R.H. handle. (Fig. 16).

4. Move primary clutch lever down into engaged ("IN") position (Fig. 14).

IMPORTANT: The safety interlock system on this unit will automatically stop the engine when the primary clutch is engaged unless the safety lever on the R.H.

handle is maintained in closed position (Fig. 16).

5. To obtain forward motion of snow thrower move 2-speed shift lever into "La" position (Fig. 7). With left hand, move shift control rod down into "For- ward" position - bottom of "Z" slot in handle plate. To stop forward motion: Move shift control rod back up into "Neutral" position - centre of "Z" slot in handle plate (Fig. 16).

6. To obtain reverse motion: With left hand, move shift control rod up into "Reverse" position and hold in

that position (Fig. 16). NOTE: Return spring (Fig. 8)

behind handle plate will automatically return shift rod to "neutral" position when shift control rod is released from "reverse" position.

7. To obtain impeller operation: IMPORTANT: Be sure front of unit is clear of bystanders or obstacles

before operating impeller. (a) Before leaving operating position to engage im-

peller clutch lever, move primary clutch lever up into disengaged ("OUT") position (Fig. 14).

IMPORTANT: The engine will always stop if the oper- ator attempts to leave the operating position and releases the safety lever without first disengaging the

primary clutch.

(b) Move impeller clutch shift rod on R.H. side of

unit to engaged ("IN") position (Fig. 15).

and squeeze safety lever on R.H. handle. Now move primary clutch lever down slowly into en- gaged ("IN") position (Fig. 14). The impeller is now operating and ready to throw snow.

8. TO DISENGAGE IMPELLER DRIVE:

(a) Before leaving operating position, disengage

primary clutch lever ("OUT" position) (Fig. 14).

(b) Move impeller shift rod to "OUT" position (Fig.

15). Impeller is now disengaged.

9. Operaticn of discharge chute and deflector: (Fig.

18). The direction of snow discharge from the chute can be varied 180°, from left to right. To discharge snow to your left, turn chute control rod handle clockwise. Rotate handle anti-clockwise to obtain snow discharge to your right. The distance the snow will be thrown can be adjusted by tilting the de- flector up or down (Fig. 18).
