OPERATION

The operation of any snow blower can result in foreign objects being thrown into the eyes,which canresult in severe eye damage. Always wear safety glasses or eye shields before beginning snow blower

Operation. We recommend standard safety glasses or Wide Vision Safety Mask for over spectacles.

SNOW BLOWER OPERATION

The most effective use of the snowblower willbe established

by experience, taking into consideration the terrain, wind

conditions and building location which will determine the

direction of the discharge chute.

NOTE: Do not blow snow towards a building as hidden

objects could be blown with sufficient force to cause

damage.

1. Start theengine as described in section"To Start Engine"

(see Figure 13).

2. Adjust snowchute deflector. Loosen wingnut on the side

of the snow chute and raise chute deflector for more dis-

tance. Tighten wing nut. (see Figure 12).

,_ WARNING: Read Owner's Manual before oper-

ating machine. This machine can be dangerous

if used carelessly.

Never operate the snow blower without all guards, cov-

ers, and shields In place.

Never direct discharge towards windows or allow by-

standers near machine while engine is running.

Stop the engine whenever leaving the operating posi-

tion.

Disconnect spark plug before unclogging the impeller

housing or the discharge chute and before making re-

pairs or adjustments.

When leaving the machine, remove the safety key.

To reduce the risk of fire, keep the machine clean and

free from spilled gas, oil and debris.

Using crank, position the discharge chute to discharge

snow with the wind.

Select proper speed for snow conditions as outlinedbe-

low and set speed selectlever to desired position.

OPERATION

BEFORE STARTING ENGINE 1.

Check the oil

NOTE: The engine was shipped from the factory filled

with oil. Check the level of the oil Add oil as needed.

Make sure the unit islevel. Use a high quality detergent

oil classified "For Service SG, SH, SJ, SL, or higher".

Remove the oil fill cap/dipstick and wipe with a clean

cloth (see Figure 16).

3. Insert the oilfillcap/dipstick and turn clockwise to tighten.

4. Remove the oil fill cap/dipstick and check the oil

NOTE: Do not check the level of the oil while the

engine runs.

5. If necessary, add oiluntil the oilreaches the FULL mark

on the oil fill/capdipstick (see Figure 16). Do not add too

much oil.

6. Tighten the fill cap/dipstick securelyeach time you check

the oil level.

NOTE: For extreme cold operating conditions of 0°F

(-18 ° C) and below, use a synthetic 5W30 motor oil for

easier starting.

NOTE: S.A.E. 5W30 motor oil may be used to make

starting easier in areas where the temperature is 20 ° F.

(-7 ° C) to O°F (-18 ° C). Synthetic 5W30 is acceptable for

all temperatures. DO NOT mix oil with gasoline,

NOTE: SEE CHART FOR OIL RECOMMENDATION

TEMPERATURE TYPE OF OIL

0°F (-18 °C) and above S.A.E. 5W30

0°F (-18 ° C) and below synthetic 5W30

Fillthefuel tank withfresh, clean, unleadedregular, un-

leaded premium, or reformulated automotive gasoline

with a minimum of 85 octane along with a fuel stabilizer

(follow instructions on fuel stabilizer package). DO NOT

use leaded gasoline. We recommend that fuel stabilizer

be added to the fuel each time that gasoline isadded to

the fuel tank.

NOTE: Winter grade gasoline has higher volatility to

improve starting. Be certain container is clean and

free from rust or other foreign particles. Never use

gasoline that may be stale from long periods of

storage in the container.

CAUTION: DO NOT use gasoline containing any

amount of alcohol as it can cause sedous damage to

the engine or significantly reduce the performance.

_k ARNING: Gasoline isflammable. Always use

caution when handling or storing gasoline.

Turn engine off and let engine cool at least two

minutes before removingthe gas cap. Do not add gaso-

line to the fuel tank while snow blower is running, hot,

or when snow blower is in an enclosed area. Keep away

from open flame, electrical sparks and DO NOT SMOKE

while filling the fuel tank. Never fill the fuel tank com-

pletely; but fill the fuel tank to within 1-1/2 inch (3.8 mm)

from the top to provide space for the expansion of the

fuel. Always fill fuel tank outdoors and use a funnel or

spout to prevent spilling, Make sure to wipe up any

spilled fuel before starting the engine.

Store gasoline in a clean, approved container, and keep

the cap in place on the container. Keep gasoline in a

cool well ventilated place; never in the house. Never

buy more than a 30 day supply of gasoline to assure

volatility. Gasoline Is intended to be used as a fuel for

internal combustion engines; therefore, do not use

gasoline for any other purpose. Since many children

like the smell of gasoline, keep it out of their reach be-

cause the fumes are dangerous to inhale, as well as be-

ing explosive.

TO START ENGINE

Be sure that engine oil is at FULL mark on the oil fill

cap/dipstick. The snow thrower engine is equipped with a 120

volt A.C. electric starter and recoil starter. Before starting the

engine, be certain that you have read the following

information.

If engine floods, set the choke to the OPEN/RUN position and

crank until the engine starts.

_lb WARNING: Rapid retraction of the starter cord(kickback) will pull your hand or arm toward the

engine faster than you can let go of the starter

cord.

•When starting the engine, slowly pull the starter cord

until resistance is felt. Then rapidly pull the starter

cord.

•Make sure components; such as impellore, pulleys

or sprockets, are securely attached.

_lb WARNING: The electric starter is equipped with

a three-wire power cord and plug designed to

operate on 120 volt AC house hold current. The

power cord must be properly grounded at all times to

avoid the possibility of electric shock which can cause

injury to the operator. Follow all instructions carefully

as set forth below:

Make sure your house has a three-wire grounded sys-

tem. If you ere not sure, ask • licensed electrician. If

your house does not have a three-wire grounded sys-

tem, do not use this electric starter under any condi-

tion.

If your house has a three-wire grounded system but a

three hole receptacle is not available to connect the

electric starter, have a three-hole receptacle installed

by a licensed electrician.

_IL WARNING: To connect a 120 volt power cord,

always connect the power cord first to the

switch box located on the engine and then plug

the other end into a three-hole grounded receptacle.

WARNING: To disconnect the power cord, al-

ways unplug the end connected to the three-

hole grounded receptacle first.

How To Start A Warm Engine

Ifrestarting a warm engine aftera shortshutdown,leave the

choke lever in the off positionand do not pushthe primer

button. If the engine fails to start, follow the Cold Start

instructions.

OPERATION

FROZEN STARTER

If the starter is frozen and willnot turn engine:

1. Pull as much rope out of the starter as possible.

2. Release the starter handle and let it snap back against

the starter. Repeat until the engine starts.

Warm engines will cause condensation in cold weather. To

help prevent possible freeze-up of recoil starter and engine

controls, proceed as follows after each snow removal job.

1. With engine off, allow engine to cool for several minutes.

2. Pull starter rope very slowly until resistance is felt, then

stop. Allow the starter rope to recoil. Repeat three times.

3. With the engine not running, wipe all snow and moisture

from the carburetor cover in area of control levers. Also

move choke knob and starter handle several times.

,_ WARNING: Never run engine indoors or In en-

closed, poorly ventilated areas. Engine exhaust

contains CARBON MONOXIDE, AN ODORLESS

AND DEADLY GAS. Keep hands, feet, hair and loose

clothing away from any moving parts on engine and

snow thrower.

•Engine parts, especially the muffler, become ex-

tremely hot. Severe thermal burns can occur on con-

tact. Allow the engine to cool before touching.

•Never allow children to operate the snow thrower.

Never allow adults to operate the snow blower with-

out proper instruction,

•Keep the area of operation clear of all persons, partic-

ularly small children and pets.

•Never leave the snow blower unattended while the

engine is running. Anyone operating the engine or

equipment must carefully read and understand the

operating instructions.

IMPORTANT: After each use of the snow blower, stop the

engine, remove the safety/ignition key, remove all

accumulated snow from the snow blower and wipe

clean. Store the snow blower in a protected area.

NOTE: Never cover snow blower while engine and

exhaust area are still warm.

HOW TO CLEAR

A CLOGGED DISCHARGE CHUTE

4_b WARNING: Hand contact with the rotating im-

peller inside the discharge chute is the most

common cause of injury associated with snow

blowers. NEVER USE YOUR HAND TO CLEAN OUT

THE DISCHARGE CHUTE.

To Clear The Chute:

•SHUT OFF THE ENGINE!

•Wait 10 seconds to be sure that the impeller blades

have stopped rotating.

•Always use a clean-out tool, not your hands.

A clean-out tool isattached to either the handle or the top of

the auger housing (see Figure 20). Use the clean-out tool to

remove snow from the auger housing.

How To Use The Clean-Out Tool

•Release the auger drivelever.

Pullcut the safety key.

• Disconnect spark plug wire.

Do not place your handsin the auger or discharge

chute. Use a clean-out tool to remove snow or debris.

,a,WARNING: Blockage must be cleared only after

shutting off the snow blower and only with a

clean-out tool, not by hand.

OPERATION

OPERATING TIPS

Most efficient snowblowingis accomplished when snow

isremoved immediately after it falls.

For complete snow removal, slightly overlap each swath

previously taken.

Snow should be discharged downwind whenever pos-

sible. 8.

For normal usage, set the skids one-eighth inch (3 mm)

below the scraper bar, For extremely hard-packed snow

surfaces, the skids may be adjusted upward to insure

cleaning efficiency.

On gravel or crushed rock surfaces,the skids should be

set at 1-1/4 inch (32 mm) below the scraper bar (see To

Adjust Skid Height, in the Adjustment/Repair section in

this manual). Rocks and gravel must not be picked up

and thrown by the machine.

After the snowblowingjob has been completed, allow the

engine to idle for a few minutes, to melt snow and ice ac-

cumulated on the engine.

Clean the snow thrower thoroughly after each use.

Remove ice and snow accumulation and all debris from

the entire snow thrower, and flush with water Ofpossible)

to remove all salt or other chemicals. Wipe snow thrower

dry.

10.

Before starting snow blower, always inspectaugers and

impeller for ice accumulation and/or debris, which could

result in snow blower damage.

Check oil level before every start. Make sure the oil isat

the FULL mark on the oil fill cap/dipstick.
