MAINTENANCE

BELTS

Check belts for deterioration and wear after every 50 hours 

of operation and replace if necessary. The belts are not 

ad just able. Replace belts if they begin to slip from wear. 

(See “TO REMOVE BELT COVER” in the Service and 

Adjustments section of this manual).
The belts on your snow thrower are of special con struc tion 

and should be replaced by original equipment man u fac tur er 

(OEM) belts avail able from your nearest dealer. Using other 

than OEM belts can cause personal injury or damage to 

the snow thrower.

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.

•  If lubricant is required, use only Ronex ED #1 grease.

TRACTION DRIVE SYSTEM

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.

CAUTION: Any lubricating of the above com po -

nents can cause contamination of the friction 

wheel and damage to the drive system of your 

snow thrower.

ENGINE

See engine manual.

LUBRICATION

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.

TO CHANGE ENGINE OIL

Determine temperature range anticipated before next oil 

change. All oil must meet API service classification SG–SL.
•  Be sure snow thrower is on level surface.
•  Oil will drain more freely when warm.
•  Catch oil in a suitable container.

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).
1.  Remove safety ignition key and disconnect spark plug 

wire from spark plug and place wire where it cannot 

come in contact with plug.

2.  Clean area around drain plug.
3.  Remove drain plug and drain oil in a suitable container.
4.  Install drain plug and tighten securely.
5.  Wipe off any spilled oil from snow thrower and engine.
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).

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 

“PRODUCT SPECIFICATIONS” section of this man u al.

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.

10.  Wipe off any spilled oil.

MUFFLER

Inspect and replace corroded muffler as it could cre ate a 

fire haz ard and/or dam age.

SPARK PLUG

Replace spark plug at the beginning of each season or after 

every 100 hours of operation, whichever occurs first.  Spark 

plug type and gap setting are shown in the “PROD UCT 

SPEC I FI CA TIONS” 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.

WARNING:  Disconnect spark plug wire 

from spark plug and place wire where it 

can not come in contact with plug.

• 

Keep finished surfaces/wheels free of gasoline, oil, etc.

•  We do not recommend using a garden hose to clean 

your snow thrower unless the electrical system, muffler 

and carburetor are covered to keep water out. Water 

in engine can result in shortened engine life.

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.
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.
Check the crankcase oil level before starting the engine and 

after each five (5) hours of continuous use. Tighten oil fill 

cap / dipstick securely each time you check the oil level.
