4. To remove the radiator cap after engine is cool, place a thick cloth over the radiator
cap. Slowly turn the radiator cap counterclockwise to the first stop. If pressurized
steam escapes from the cap, stand back to avoid injury. After all pressure is
released, push down and turn the radiator cap counterclockwise to remove.
Gauges And Lights
The gauges and lights shown are typical and represent various options that can be used.
See the equipment manual for location and operation of gauges and lights.
Coolant Temperature Gauge
Indicates coolant temperature when the electric start switch is in
the ON position.
Normal range 80º -- 90º C (175º -- 195º F)
Dangerous range above 105º C (220º F)
Hour Meter Gauge
Indicates the total number of operating hours.
Fuel Gauge
Indicates the fuel remaining in the fuel tank. To minimize condensation,
keep the fuel tank full.
Temperature Light
If the temperature light comes on, the engine is overheating. Stop the
engine and check the coolant level (see the How To Check Coolant
section). Check the radiator for debris that could restrict air flow.
Ignition Light
When the electric start switch is turned to the ON position, the ignition light
should be on. When the engine is running, the ignition light should go out.
If the ignition light is out when then electric start switch in the ON position, check for a
blown fuse.
Engine Oil Pressure Light
When the electric start switch is turned to the ON position, the engine oil
pressure light should be on. When the engine is running, the engine oil
pressure light should go out. If the engine oil pressure light comes on when the engine
is running, immediately stop the engine. First, check the oil level (see the How To
Check/Add Oil section). Next, check the electrical system.
Charge Light
When the electric start switch is turned to the ON position, the charge light
should be on. When the engine is running, the charge light should go out.
If the charge light comes on when the engine is running, check the electrical system.
Heat or Glow Light
When the ignition switch is turned to the heat/glow or the on position, the
glow light will indicate to indicate that the glow plugs are preheating the
combustion chamber.
X
Fuel Filter Light
The fuel filter light comes on when excess water has collected in the fuel
filter. The light should go out when the excess water is drained from the
fuel filter. If the fuel filter warning light illuminates while engine is running, stop the engine
and drain the water from the fuel filter.

NOTICE: This engine was shipped from Briggs & Stratton without oil. Before you start
the engine, make sure 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 warranty.
NOTICE: Before starting the engine for the first time, charge the battery as
recommended by the equipment manufacturer. Failure to do so can cause damage to the
engine.
Note: Some engines and equipment have remote controls. See the equipment manual
for location and operation of remote controls.
1. Check the oil level. See the How To Check/Add Oil section.
2. Make sure equipment drive controls, if equipped, are disengaged.
3. Turn the fuel shut-off valve (A), if equipped, to the on position (Figure 6).
4. Move the throttle control (B) to the slow
Note: For starting in cold weather (below -10º C or 14º F), move the throttle control to
the fast position.
5. Turn the electric start key (C) to the ON position (Figure 6). The glow light will
indicate that the glow plugs are preheating the combustion chamber.
6. When the glow light goes out, turn the electric start key to the START position.
NOTICE: To prolong starter life, use short starting cycles, not to exceed 15 seconds
per minute. Extended cranking can damage the starter motor.
7. When the engine starts, release the key. The glow light will illuminate for about 20
seconds and then go out.
NOTICE: Do not accelerate or race a cold engine. Failure to observe this notice can
cause engine damage.
8. Allow the engine to run and warm up for several minutes before operating the
equipment.
How To Stop The Engine - Figure 6

NOTICE: Before stopping a turbo-equipped engine, allow the engine to idle for one
minute to cool the turbocharger. Failure to do so can damage the turbocharger.
2. Turn the key switch (C) to the off position (Figure 6). Remove the key and keep in a
safe place out of the reach of children.
3. After the engine stops, turn the fuel shut-off valve (A), if equipped, to the closed
position.
Maintenance
See any Briggs & Stratton 3/LC Dealer for correct replacement parts. Other parts may
not perform as well, may damage the engine, result in injury, or void your warranty.
NOTICE: All the components used to build this engine must remain in place for proper
operation.
NOTICE: The manufacturer of the equipment on which this engine is installed specifies
the top speed at which the engine will be operated. Do not exceed this speed.
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. See the Emissions Warranty.
WARNING
Unintentional start-up can result in entanglement, traumatic
amputation, or laceration.
Fire hazard
Before performing adjustments or repairs:
Disconnect battery at negative terminal (only engines with electric start.)

Use only correct tools.

Do not tamper with governor spring, links or other parts to increase engine

speed.
Replacement parts must be of the same design and installed in the same
