WARNING

•   Disengage all clutches and shift into neutral before starting 

the engine.

•   Let the engine adjust to outdoor temperatures before 

starting to clear snow.

•   Use a grounded three-wire plug for all snowthrowers 

equipped with electric drive motors or electric starting 
motors.

WARNING

•   If there is natural or LP gas leakage in area, do not start 

engine.

•   Do not use pressurized starting fluids because vapors are 

flammable.

WARNING

•   Never touch a hot engine or muffler. Allow muffler, engine 

cylinder, and fins to cool before touching.

•   Remove debris from muffler area and cylinder area.

•   Install and maintain in working order a spark arrester before 

using equipment on forest-covered, grass-covered, or 
brush-covered unimproved land. 

•   It is a violation of California Public Resource Code, 

Section 4442, to use or operate the engine on any forest-
covered, brush-covered, or grass-covered land unless 
the exhaust system is equipped with a spark arrester, as 
defined in Section 4442, maintained in effective working 
order. Other states or federal jurisdictions may have 
similar laws. Contact the original equipment manufacturer, 
retailer, or dealer to obtain a spark arrester designed for the 
exhaust system installed on this engine.

Starting engine creates sparking.

Sparking can ignite nearby flammable gases.

Explosion and fire could result.

Running the engine produces heat. Engine 
parts, especially muffler, become extremely 
hot. 

Failure to observe these safety instructions 
could result in severe thermal burns on contact.

Safe operation of the snowthrower requires 
the proper care and maintenance of the 
engine. 

WARNING

•   When performing any maintenance or repairs on the 

snowthrower, shut OFF the engine, disconnect spark plug 
wire, and keep the wire away from the 

plug to p

revent 

someone from accidently starting the engine.

•   Check shear bolts and other hardware at frequent intervals 

for proper tightness.

•   Keep nuts and bolts tight and keep snowthrower in good 

condition.

•   Never tamper with safety devices. Check their proper 

operation regularly and make necessary repairs if they are 
not functioning properly.

•   Components are subject to wear, damage, and deterioration. 

Frequently check components and replace with 
recommended parts, when necessary.

•   Check control operation frequently. Adjust and service as 

required.

•   Use only factory authorized replacement parts, or like, parts 

when making repairs. 

•   Always comply with factory specifications on all settings and 

adjustments.

•   Use only factory authorized, or like, attachments and 

accessories such as wheel weights, counterweights, or cabs.

•   Never attempt to make any adjustments while the engine 

is running (except when specifically recommended by the 
factory).

This snowthrower must be properly 
maintained to ensure safe operation and 
performance. Failure to observe the safety 
instructions in this manual could result in 
death or serious injury.
