High Altitude - Briggs & Stratton P4500 Handbuch

Operation Location to Reduce the Risk of Fire
WARNING! Exhaust heat/gases could
ignite combustibles, structures or
damage fuel tank causing a fire,
resulting in death or serious injury.
• Portable generator must be at least 1.5 m from any
structure, overhang, trees, shrubs, or vegetation over
30.5 cm in height.
• Do not place portable generator under a deck or
other type of structure that may confine airflow.
Smoke alarm(s) must be installed and maintained
indoors according to the manufacturer's instructions/
recommendations.
• Carbon monoxide alarms cannot detect smoke.
• Do not place portable generator in manner other than
shown.

Step 2: Oil and Fuel
Oil Recommendations Figure
We recommend the use of Briggs & Stratton Warranty
Certified oils for best performance. Other high-quality
detergent oils are acceptable if classified for service SF
or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity
for the engine. Use the chart to select the best viscosity
for the outdoor temperature range expected.
* Below 4°C (40°F) the use of SAE 30 will result in hard starting.
** Above 27°C (80°F) the use of 10W30 may cause increased oil
consumption. Check oil level more frequently.
Checking/Adding Engine Oil Figure
Oil level should be checked prior to each use or at least
every 8 hours of operation. Keep oil level maintained.
1. Make sure generator is on a level surface.
2. Turn dial and open cover (5) over oil fill area.
3. Clean area around oil fill and remove dipstick.
4. Verify oil is at the full mark (6, A) on dipstick.
5. If needed, using oil funnel, slowly pour oil into oil fill
opening (7) to full mark (6, A) on dipstick.
NOTICE Pause to permit oil to settle. Wipe dipstick
clean each time oil level is checked. DO NOT overfill.
6. Replace and tighten dipstick.
7. Replace cover over oil fill area.
NOTICE Do not attempt to crank or start engine before
before it has been properly serviced with recommended
oil. This could result in an engine failure.

Add Fuel Figure

Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline with a minimum of
91 RON (87 octane/87 AKI).
• Gasoline with up to 10% ethanol content is acceptable.
NOTICE Do not mix oil in gasoline or modify engine to
run on alternate fuels. Do not use unapproved gasoline
such as E15 and E85. Use of unapproved fuels could
damage generator and voids warranty.
See High Altitude for 1,524 m and above.
WARNING! Fuel and its vapors
are extremely flammable which
could cause burns or fire resulting
in death or serious injury.
• Do not refuel or move during operation.
• Turn engine off and let it cool at least 2 minutes before
removing fuel cap.
• Fill fuel tank outdoors. Do not spill 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.
• Do not light a cigarette or smoke.
• Do not pour water on generator to put out fire.
• Only use a extinguisher rated for flammable liquids
and electrical systems such as a powder extinguisher.
Follow the instructions provided by fire extinguisher
manufacturer before use.
• This generator is not for use in explosive atmospheres.
1. Slowly remove fuel cap (1, J) to relieve pressure in
tank.
2. Slowly add unleaded fuel to max fill indicator (8, A)
in fuel tank. Be careful not to fill above the indicator.
This allows adequate space for fuel expansion.
3. Install fuel cap and let any spilled fuel evaporate
before starting engine.

High Altitude

At altitudes over 1524 m, a minimum 89 RON
(85 octane/85 AKI) fuel is acceptable. To remain
emissions compliant, high altitude adjustment is required.
Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions.
See an Authorized Briggs & Stratton dealer for high
altitude adjustment information. Operation of the engine
at altitudes below 762 m with the high altitude kit is not
recommended.
Transporting
When transporting equipment, turn fuel valve to
off ( ) position. Do not tip engine or equipment at angle
which causes fuel to spill.
Low Oil Indicator
The low oil indicator system is designed to prevent
engine damage caused by not enough engine oil. If the
engine oil level drops below a preset level, the red LED
low oil indicator light comes on and an oil level switch will
stop the engine. If the engine stops or the red LED low
oil indicator light comes on when you press the activate
switch, check the engine oil level.
