We recommend contacting an authorized service dealer for all
maintenance, adjustments, and servicing of the unit. Some
routine maintenance tasks can be performed by the owner.
Refer to the maintenance schedule and procedures that follow.
CAUTION
All the components used to build this product must remain in
place for proper operation. Replacement parts must be of the
same design and installed in the same position as the orginial
parts. Other parts may not perform as well, may damage the
unit, and may result in injury.

Emissions Control

Maintenance, replacement, or repair of the emissions control

repair establishment or individual. However, to obtain "no
charge" emissions control service, the work must be performed
by a factory authorized dealer.

Changing the Engine Oil

Used oil must be disposed of properly. 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 resulting in death or serious injury.
• When performing maintenance that requires the unit to
be tipped, 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 8) and tilt the
snowthrower slightly to drain the oil into an appropriate
container.
