Vanguard 25V000, Operator'S Manual

WARNING 

POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a

poisonous gas that could kill you in minutes. Although you do not smell exhaust

fumes, you could still be exposed to dangerous carbon monoxide gas. If you feel

sick, dizzy, or weak while you use this product, get to fresh air RIGHT AWAY. See

a doctor. You may have carbon monoxide poisoning.

•

Carbon monoxide gas can collect in occupied spaces. To reduce the risk of

carbon monoxide gas, ONLY operate this product outdoors and far away from

windows, doors and vents.

•

Install battery-operated carbon monoxide alarms or plug-in carbon monoxide

alarms with battery back-up as specified by the manufacturer's instructions.

Smoke alarms cannot sense carbon monoxide gas.

•

DO NOT operate this product in homes, garages, basements, crawlspaces,

sheds, or other closed spaces, even if you use fans or open doors and windows

for ventilation. After the operation of this product, carbon monoxide can quickly

collect in these spaces and stay for hours.

•

ALWAYS put this product downwind and point the engine exhaust away from

occupied spaces.

NOTICE 

This engine was shipped from Briggs & Stratton without oil. Equipment manufacturers or

dealers could have added oil to the engine. Before you start the engine for the first time,

make sure that the oil is at the correct level. Add oil as specified by the instructions in

this manual. If you start the engine without oil, damage will occur and the engine will not

be repaired under warranty.

NOTE: 

Your equipment could have remote controls. Refer to the equipment manual for

location and operation of remote controls.
1. Check the engine oil. Refer to 

Check Oil Level

 section.

2. Make sure that the equipment drive controls, if equipped, are disengaged.
3. Move the throttle control lever / TransportGuard

®

 (A, Figure 17), if equipped, to the

FAST or RUN position. Operate the engine in the FAST or RUN position.

4. Move the choke control (B, Figure 17) to the CLOSED position.

The choke is usually not necessary when you start a warm engine.

5.

Rewind Start, if equipped:

 Tightly hold the starter cord handle (C, Figure 17). Pull

the starter cord handle slowly until resistance is felt, then pull quickly.

WARNING 

Fast retraction of the starter cord (kickback) will pull your hand and arm to the

engine faster than you can let go. Broken bones, fractures, bruises or sprains

could result.

• To prevent kickback when you start the engine, pull the starter cord slowly until

resistance is felt and then pull quickly.

• Before you start the engine, disconnect or remove all external equipment and

engine loads.

• Make sure that direct-coupled equipment components, such as, but not limited to,

blades, impellers, pulleys, and sprockets, are correctly attached.

6.

Electric Start, if equipped:

 Turn the electric start switch (D, Figure 17) to the

START position.

NOTICE 

To extend the life of the starter, use short start cycles (five seconds maximum). Wait one

minute between start cycles.

7. As the engine warms, move the choke control (B, Figure 17) to the OPEN position.

If the engine does not start after 2 or 3 times, contact your local dealer or go to 

vanguardpower.com or call 1-800-999-9333 (in USA).

Stop the Engine

WARNING 

Fuel and its vapors are flammable and explosive. Fire or explosion could result in

burns or death.

•

Do not choke the carburetor (if equipped) to stop the engine.

Throttle Control / TransportGuard

®

:

 Move the throttle control / TransportGuard

®

 (A,

Figure 18) to the OFF or STOP position.

NOTE: 

When the throttle control / TransportGuard

®

 (A, Figure 18) is in the OFF

or STOP position, the fuel valve is in the OFF position. Always move the throttle
control / TransportGuard

®

 to the OFF or STOP position during transport of the

equipment.

children.

Maintenance

Maintenance Information

WARNING 

During maintenance if it is necessary to tilt the unit, make sure that the fuel tank, if

mounted on the engine, is empty and that the spark plug side is up. If the fuel tank is not

empty, leakage can occur and could result in a fire or an explosion. If the engine is tilted

in a different direction, it will not easily start because of oil or fuel contamination of the air

filter or the spark plug.
We recommend that you see a Briggs & Stratton Authorized Service Dealer for all

maintenance and servicing of the engine and engine parts.

NOTICE 

All the components used to build this engine must remain in place for correct operation.

WARNING 

Accidental engine spark can cause an electric shock or fire and could result in

entanglement, traumatic amputation or laceration.

Before you make adjustments or repairs:

•

Disconnect the spark plug wire and keep it away from the spark plug.

•

Disconnect the battery wire from the negative battery terminal (only engines with

electric start.)

•

Use only the correct tools.

When you check for spark:

•

Use an approved spark plug tester.

•

Do not check for spark with the spark plug removed.

Emissions Control Service

For maintenance, replacement, or repair of emissions control devices and

systems, contact a qualified off-road engine repair establishment or service

technician.

 However, for "no charge" emissions control service, the work must be done

by a factory authorized dealer. Refer to the Emissions Control Statements.
