Starting The Engine; Adding Fuel - Briggs & Stratton Victa 46 23HP Manual Del Operador

• 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
maintain performance. 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.

Adding Fuel

WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or death.
When Adding Fuel
• Turn engine off and let engine cool at least 3 minutes
before removing the fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. To allow for expansion of the fuel,

• Keep fuel away from sparks, open flames, pilot lights,
heat, and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently for
cracks or leaks. Replace if necessary.
• If fuel spills, wait until it evaporates before starting engine.
1. Clean the fuel cap area of dirt and debris. Remove the fuel
cap (A, Figure 4).
2. Fill the fuel tank with fuel. To allow for expansion of the fuel,
do not fill above the bottom of the fuel tank neck (B).

Starting the Engine

WARNING
• If you do not understand how a specific control functions,
or have not yet thoroughly read the Features & Controls
section, do so now.
• Do NOT attempt to operate the tractor without first
becoming familiar with the location and function of all
controls.
1. While sitting in the operator's seat, make sure the PTO
switch is disengaged and the ground speed control levers
are locked in the START/PARK position.
Note: The parking brake is automatically engaged when the
ground speed levers are locked in the START/PARK position.
2. Set the engine speed control past the FAST position to the
CHOKE position.
Note: A warm engine does not require choking.
Note: Some engines are equipped with a separate choke control.
Note: Some engines are equipped with a ReadyStart® feature,
and do not feature a choke.
3. Insert the key into the ignition switch and turn it to START.
4. After the engine starts, turn off the choke (if equipped), and
warm up the engine by running it for at least a minute before
engaging the PTO switch or driving the rider.
5. After warming the engine, always operate the unit at full
engine speed when mowing.

1. Return the ground speed levers to the middle (or neutral
'N' ) position to stop rider movement. Pivot the levers
outward to lock them in the START/PARK position.
Note: Moving the ground speed levers to the START/ PARK
position automatically engages the parking brake.
2. Disengage the PTO by pushing down on the PTO switch.
3. Move the engine speed control to the SLOW position and
turn the ignition switch to OFF. Remove the key.
