Emissions Control

Maintenance, replacement, or repair of the emissions control
devices and systems may be performed by any non-road engine
repair establishment or individual. However, to obtain "no
charge" emissions control service, the work must be performed
by a factory authorized dealer.
Changing the Oil
Used oil must be discarded correctly. Do not discard with
household waste. Check with your local authorities, service
center, or dealer for safe disposal or recycling facilities.
Use Briggs & Stratton Synthetic 5W-30 Warranty Certified oil
for best performance. Other high-quality detergent oils are
acceptable if classified for service SG, SH, SJ or higher. Do not
use any additives.
1. With the engine stopped but still warm, turn the ignition key
to the OFF position and remove it or pull out the push/pull
key (if equipped).
WARNING
Fuel and its vapors are extremely flammable, which could
cause burns or fire that result in death or serious injury.
• During maintenance, the fuel tank must be empty or
fuel can leak out and result in a fire or explosion.
2. Remove the oil drain plug (D, Figure 18). Carefully tilt the
snowthrower and drain the oil into a container.
