Operation - Snapper 922EXD Operator's Manual

Oil Recommendations
NOTICE: The engine was shipped from the factory without oil.
Before you start the engine, ensure that you add oil according to
the instructions in this manual. If you start the engine without oil, it
will be damaged beyond repair and will not be covered under the
warranty.
Use a high quality detergent oil classified for Service SG, SH,
SJ, SL, or higher. Synthetic 5W30 motor oil is acceptable for all
temperatures. DO NOT mix oil with gasoline. See chart below for
oil recommendations.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil con-
sumption. Check oil level more frequently.
Add Oil / Check Oil Level
1. Ensure the snowthrower is level.
2. Clean the oil dipstick area of any debris.
3. See Specifications for the oil capacity.
4. Remove the oil dipstick (A, Figure 1) and wipe it with a clean
cloth.
5. Add oil slowly into the engine oil fill (B).
6. Wait one minute and then insert the oil dipstick and turn it
clockwise to tighten.
7. Remove the oil dipstick and check the oil level.
8. If necessary, add oil until the level reaches the full mark (C) on
the oil dipstick. Do not overfill.
9. Insert and tighten the oil dipstick securely.

Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). For high altitude
use, see below.
• Gasoline with up to 10% ethanol (gasohol) is acceptable.
NOTICE: Do not use unapproved gasolines, such as E15 and
E85. Do not mix oil in gasoline or modify the engine to run on
alternate fuels. Use of unapproved fuels will cause damage to
engine components, which will not be covered under warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See Storage. All fuel is not the same. If
starting or performance problems occur, change fuel providers
or change brands. This engine is certified to operate on gasoline.
The emissions control system for this engine is EM (Engine
Modifications).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85 octane
/ 85 AKI (89 RON) gasoline is acceptable. For carbureted
engines, high altitude adjustment is required to remain emissions
compliant. Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. Contact a Briggs & Stratton Authorized Service Dealer
for high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude adjustment is not recommended.
For Electronic Fuel Injection (EFI) engines, no high altitude
adjustment is necessary.
