and all moving parts have stopped. Disconnect the  
spark plug wire and keep the wire away from the plug  
to prevent someone from accidentally starting the en-  
gine.  
Clearing a Clogged Discharge Chute  
Handcontactwiththerotatingimpellerinsidethedischarge  
chute is the most common cause of injury associated with  
snow throwers. Never use your hand to clean out the dis-  
charge chute. To clear the chute:  
1. SHUT THE ENGINE OFF!  
7. Do not run the engine indoors, except when starting  
the engine and for transporting the snow thrower in or  
out of the building. Open the outside doors; exhaust  
fumes are dangerous.  
2. Wait 10 seconds to be sure the impeller blades have  
stopped rotating.  
3. Always use a clean-out tool, not your hands.  
8. Exercise extreme caution when operating on slopes.  
Maintenance and Storage  
1. Check shear bolts and other bolts at frequent intervals  
for proper tightness to be sure the equipment is in safe  
working condition.  
9. Neveroperatethesnowthrowerwithoutproperguards,  
and other safety protective devices in place and work-  
ing.  
10. Never direct the discharge toward people or areas  
where property damage can occur. Keep children  
and others away.  
2. Never store the machine with fuel in the fuel tank  
inside a building where ignition sources are present  
such as hot water heaters, space heaters, or clothes  
dryers. Allow the engine to cool before storing in any  
enclosure.  
11. Do not overload the machine capacity by attempting  
to clear snow at too fast a rate.  
12. Never operate the machine at high transport speeds  
on slippery surfaces. Look behind and use care when  
operating in reverse.  
3. Always refer to operator’s manual for important details  
if the snow thrower is to be stored for an extended  
period.  
13. Disengage power to the collector/impeller when snow  
thrower is transported or not in use.  
4. Maintain or replace safety and instruction labels, as  
necessary.  
14. Use only attachments and accessories approved by  
the manufacturer of the snow thrower (such as wheel  
weights, counterweights, or cabs).  
5. Run the machine a few minutes after throwing snow  
to prevent freeze-up of the collector/impeller.  
15. Never operate the snow thrower without good visibility  
or light. Always be sure of your footing, and keep a firm  
hold on the handles. Walk; never run.  
16. Never touch a hot engine or muffler.

OPERATION  
TO ADJUST SKID PLATES (See Fig. 17)  
To change engine oil, see “TO CHANGE ENGINE OIL”  
in the Maintenance section of this manual.  
NOTE:Thewrenchprovidedinyourpartsbagmaybeused  
to adjust the skid plates.  
ADD GASOLINE (See Fig. 18)  
Skid plates are located on each side of the auger housing  
and adjust the clearance between the scraper bar and the  
ground surface. Adjust skid plates evenly to proper height  
for current surface conditions. For removal of snow in  
normal conditions, such as a paved driveway or sidewalk,  
place skid plates in the highest position (lowest scraper  
clearance) to give a 1/8" clearance between the scraper  
bar and the ground. Use a middle position if the surface  
to be cleared is uneven.  
Fill fuel tank to bottom of tank filler neck. Do not over-  
fill. Use fresh, clean, regular unleaded gasoline with  
a minimum of 87 octane. Do not mix oil with gasoline.  
Purchase fuel in quantities that can be used within 30  
days to assure fuel freshness.  
WARNING: Wipe off any spilled oil or  
fuel. Do not store, spill or use gasoline  
near an open flame.  
NOTE: It is not recommended to operate the snow thrower  
overgravelorrockysurfaces.Objectssuchasgravel,rocks  
or other debris, can easily be picked up and thrown by the  
impeller, which can cause serious personal injury, property  
damage or damage to the snow thrower.  
CAUTION: Alcohol blended fuels (called gas-  
ohol or using ethanol or methanol) can attract  
moisture which leads to separation and for-  
mation of acids during storage. Acidic gas can  
damage the fuel system of an engine while in  
storage. To avoid engine problems, the fuel  
system should be emptied before storage of  
30 days or longer. Empty the gas tank, start  
the engine and let it run until the fuel lines and  
carburetor are empty. Use fresh fuel next sea-  
son. See Storage Instructions for additional  
information. Never use engine or carburetor  
cleaner products in the fuel tank or permanent  
damage may occur.  
If snow thrower must be operated over gravel surface,  
use extra caution and be sure skid plates are adjusted  
to lowest (highest scraper clearance) position.  
1. Shut off engine and wait for all moving parts to stop.  
2. Adjust skid plates by loosening the rear 1/2" hex nut

OPERATION  
TO START ENGINE  
SNOW THROWING TIPS  
Be sure fuel shut-off valve is in the OPEN position.  
Always operate the snow thrower with the engine at  
full throttle. Full throttle offers the best performance.  
Your snow thrower engine is equipped with a recoil starter.  
COLD START  
Goslowerindeep,freezingorheavywetsnow.Usethe  
drive speed control, NOT the throttle, to adjust speed.  
1. Insert safety ignition key into the ignition slot until it  
clicks. DO NOT turn the key. Keep the extra safety  
ignition key in a safe place.  
It is easier and more efficient to remove snow imme-  
diately after it falls.  
The best time to remove snow is the early morning. At  
this time the snow is usually dry and has not been ex-  
posed to the direct sun and warming temperatures.  
2. Place throttle control in FAST position.  
3. Rotate choke control to FULL position.  
4. Push the primer four (4) times if the temperature is  
below 15°F, or two (2) times if temperature is between  
15° and 50°F. If temperature is above 50°F, priming is  
not necessary.  
Slightly overlap each successive path to ensure all  
snow will be removed.  
Throw snow downwind whenever possible.  
Adjust the skid plates to proper height for current snow  
conditions. See “TO ADJUST SKID PLATES” in this  
section of this manual.  
NOTE: Over priming may cause flooding, preventing the  
engine from starting. If you do flood the engine, wait a few  
minutes before attempting to start and DO NOT push the  
primer.  
For extremely heavy snow, reduce the width of snow  
removal by overlapping previous path and moving  
slowly.  
5. Pull recoil starter handle quickly. Do not allow starter  
rope to snap back.  
Keep engine clean and clear of snow during use. This  
will help air flow and extend engine life.  
6. When the engine starts, release the recoil starter  
handle and slowly move the choke control to the OFF  
position.  
Aftersnow-throwingiscompleted,allowenginetorunfor  
a few minutes to melt snow and ice off the engine.  
Allow the engine to warm up for a few minutes. Engine will  
not develop full power until it has reached normal operat-  
ing temperature.  
Clean the entire snow thrower thoroughly after each  
use and wipe dry so it is ready for next use.  
WARM START  
WARNING: Do not operate snow

hazardous to the safe operation of the  
snow thrower.  
Follow the steps above, keeping the choke in the OFF  
position. DO NOT push the primer.  
BEFORE STOPPING  
Run the engine for a few minutes to help dry off any mois-  
ture on the engine.  
To avoid possible freeze-up of the starter, proceed as  
follows:  
1. Whiletheengineisrunning,pulltherecoilstarterhandle  
with rapid, full arm strokes three or four times.  
NOTE: The unusual sound made while pulling the recoil  
starter handle will not harm the engine or starter.  
IF RECOIL STARTER HAS FROZEN  
If the recoil starter has frozen and will not turn the engine,  
proceed as follows:  
1. Grasp the recoil starter handle and slowly pull as much  
rope out of the starter as possible.  
2. Release the recoil starter handle and let it snap back  
against the starter.  
If the engine still fails to start, repeat the above steps.

than OEM belts can cause personal injury or damage to  
the snow thrower.  
NOTE: The left side wheel may be removed from snow  
thrower for easier access to the oil drain plug and place-  
ment of a suitable container. The unit tilted, resting on the  
frame with the left wheel removed, will help drain any oil  
trapped inside the engine. (See “TO REMOVE WHEELS”  
in the Service and Adjustments section of this manual).  
AUGER GEAR CASE  
The gear case was filled with lubricant to the proper  
level at the factory. The only time the lubricant needs  
attention is if service has been performed on the gear  
case.  
1. Disconnect spark plug wire from spark plug and place  
wire where it cannot come in contact with plug.  
2. Clean area around drain plug.  
If lubricant is required, use only Ronex ED #1 grease.  
3. Remove drain plug and drain oil in a suitable container.  
4. Install drain plug and tighten securely.  
TRACTION DRIVE SYSTEM  
5. Wipe off any spilled oil from snow thrower and engine.  
DO NOT lubricate the drive components inside the snow  
thrower. The sprockets, hex shafts, drive disc and friction  
wheel require no lubrication. The bearings and bushings  
are lifetime lubricated and require no maintenance.  
6. Install left wheel (if removed for draining oil). Be sure to  
install klick pin into proper hole in wheel axle (See “TO  
REMOVE WHEELS” in the Service and Adjustments  
section of this manual).  
CAUTION:Anylubricatingoftheabovecompo-  
nents can cause contamination of the friction  
wheel and damage to the drive system of your  
snow thrower.  
7. Remove oil fill cap/dipstick. Be careful not to allow dirt  
to enter the engine.  
8. Refill engine with oil through oil dipstick tube. Pour  
slowly. Do not overfill. For approximate capacity see  
“PRODUCTSPECIFICATIONSsectionofthismanual.  
ENGINE  
See engine manual.  
9. Use gauge on oil fill cap/dipstick for checking level. Be  
sure dipstick cap is tightened securely for accurate  
reading. Keep oil at “FULL” line on dipstick.  
LUBRICATION  
10. Wipe off any spilled oil.  
Use only high quality detergent oil rated with API service  
classification SG–SL. Select the oil's SAE viscosity grade  
according to your expected operating temperature.  
MUFFLER  
Inspect and replace corroded muffler as it could create a  
fire hazard and/or damage.  
SPARK PLUG  
Replacesparkplugatthebeginningofeachseasonorafter  
every100hoursofoperation,whicheveroccursrst. Spark  
plug type and gap setting are shown in the “PRODUCT  
SPECIFICATIONS” section of this manual.  
CLEANING  
IMPORTANT: For best performance, keep snow thrower  
housing free of any dirt or trash. Clean the outside of your  
snow thrower after each use.  
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)  
improve starting in cold weather, these multi-viscosity oils  
will result in increased oil consumption when used above  
32°F. Check your engine oil level more frequently to avoid  
possible engine damage from running low on oil.  
WARNING: Disconnectsparkplugwire  
fromsparkplugandplacewirewhereit  
cannot come in contact with plug.  
Change the oil after every 25 hours of operation or at least  
once a year if the snow thrower is not used for 25 hours  
in one year.  
Keepnishedsurfaces/wheelsfreeofgasoline,oil,etc.  
We do not recommend using a garden hose to clean  
yoursnowthrowerunlesstheelectricalsystem,muffler  
and carburetor are covered to keep water out. Water  
in engine can result in shortened engine life.  
Checkthecrankcaseoillevelbeforestartingtheengineand  
after each five (5) hours of continuous use. Tighten oil fill  
cap / dipstick securely each time you check the oil level.

IMPORTANT: It is important to prevent gum deposits from  
forming in essential fuel system parts such as carburetor,  
fuelhose,ortankduringstorage.Also,alcoholblendedfuels  
(called gasohol or using ethanol or methanol) can attract  
moisture which leads to separation and formation of acids  
during storage. Acidic gas can damage the fuel system of  
an engine while in storage.
