boards, wires and other foreign objects, which could be

tripped over or thrown by the auger/impeller.

2. Always wear safety glasses or eye shields during

operation and while performing an adjustment or repair to

protect your eyes. Thrown objects which ricochet can

cause serious injury to the eyes.

3. Do not operate without wearing adequate winter outer

garments. Do not wear jewelry, long scarves or other

loose clothing, which could become entangled in moving

parts. Wear footwear which will improve footing on

slippery surfaces.

4. Use a grounded three-wire extension cord and

receptacle for all units with electric start engines.

5. Adjust collector housing height to clear gravel or crushed

rock surfaces.

6. Disengage all clutch levers before starting the engine.

Never attempt to make any adjustments while engine is

running, except where specifically recommended in the

operator's manual.

Let engine and machine adjust to outdoor temperature

before starting to clear snow.

To avoid personal injury or property damage use extreme

care in handling gasoline. Gasoline is extremely

flammable and the vapors are explosive. Serious

personal injury can occur when gasoline is spilled on

yourself or your clothes, which can ignite. Wash your skin

and change clothes immediately.

a. Use only an approved gasoline container.

b. Extinguish all cigarettes, cigars, pipes and other

sources of ignition.

c. Never fuel machine indoors.

d. Never remove gas cap or add fuel while the

snap back. Allow it to rewind slowly while keeping a

firm hold on the starter handle.

• Repeat step above until engine starts.

• As engine warms up and begins to operate evenly,

rotate choke knob slowly to OFF position. If engine

falters, return to FULL choke, then slowly move to

OFF position.

Electric Starter

The electric starter is equipped with a grounded three-

wire power cord and plug, and is designed to operate

on 120 volt AC household current.

WARNING: The electric starter must be

used with a properly grounded three-prong

receptacle at all times to avoid possibility of

electric shock. Follow all instructions carefully

to operate the electric starter.

• Determine that your house wiring is a three-wire

grounded system. Ask a licensed electrician if you

are not certain.

•If your home wiring system is not athree-wire

grounded system, do not use this electric starter

under any conditions.

• If your home electrical system is grounded, but

a three-hole receptacle is not available, one should

be installed by a licensed electrician before using

the electric starter.

•If you have agrounded three-prong receptacle,

proceed as follows:

• Connect power cord to switch box on engine. Plug

the other end of power cord into a three-prong 120-

volt, grounded, AC receptacle.

• Rotate choke knob to FULL choke position (cold

engine start). If engine is warm, place choke in OFF

position instead of FULL.

• Push primer button two or three times for cold

engine start, making sure to cover vent hole in

primer button when pushing. DO NOT use primer to

restart a warm engine after a short shutdown.

• Push starter button to start engine.

• When engine starts, release starter button and

move choke gradually to OFF. If engine falters,

move choke immediately to FULL and then

AugerControlTest

IMPORTANT:Perform the following test before operating

the snow thrower for the first time and at the start of

each winter season.

Check the adjustment of the auger control as follows:

• When the auger control is released and in the

disengaged "up" position, the cable should have

very little slack, but should NOT be tight.

,_ WARNING" Do not over-tighten the cable.

Over-tightening may prevent the auger from

disengaging and compromise the safety of the

snow thrower.

• In a well-ventilated area, start the snow thrower

engine as instructed earlier in this section under the

heading StartingEngine.Make sure the throttle is set

in the FAST position.

• While standing in the operator's position (behind

the snow thrower) engage the auger.

• Allow the auger to remain engaged for

approximately ten (10) seconds before releasing

the auger control. Repeat this several times.

• With the engine running in the FAST position and

the auger control lever in the disengaged "up"

position, walk to the front of the machine.

• Confirm that the auger has completely stopped

rotating and shows NO signs of motion.

IMPORTANT: If the auger shows ANY signs of rotating,

immediately return to the operator's position and shut

off the engine. Wait for all moving parts to stop before

readjusting the auger control cable.

• To readjust the control cable, loosen the hex jam

nut on the auger control cable "Z" fitting.

• Rotate the coupling end of the cable

counterclockwise to provide more slack.

• Retighten the hex jam nut. See Figure 16.
