Oil Recommendations
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,
SG, SH, SJ 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.
°F
* 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 consumption. Check
oil level more frequently.
How To Check/Add Oil - Figure 2
Before adding or checking the oil
Place engine level.
•
Clean the oil fill area of any debris.
•
1. Remove the dipstick (A) and wipe with a clean cloth (Figure 2).
2. Fully insert the dipstick.
3. Remove the dipstick and check the oil level. It should be at the top of the full indicator
(B) on the dipstick.
4. If low, add oil slowly into the engine oil fill (C). Do not overfill. After adding oil, wait
one minute and then recheck the oil level.
5. Fully insert the dipstick.
Oil Pressure
If the oil pressure is too low, a pressure switch (if equipped) will either stop the engine or
activate a warning device on the equipment. If this occurs, stop the engine and check the
oil level with the dipstick.
If the oil level is below the ADD mark, add oil until it reaches the FULL mark. Start the
engine and check for proper pressure before continuing to operate.
If the oil level is between the ADD and FULL marks, do not start the engine. Contact an
Authorized Briggs & Stratton Dealer to have the oil pressure problem corrected.

Fuel Recommendations
Do not operate the equipment if the "fuel lock-off" valve is missing or inoperative.
•
Fuel must meet these requirements:
Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside
•
the following recommended values may cause performance problems.
In engines set up to run on LPG, commercial grade HD5 LPG is recommended.
•
Recommended fuel composition is fuel with a minimum fuel energy of 2500 BTU's/ft
with maximum propylene content of 5% and butane and heavier gas content of 2.5%
and minimum propane content of 90%.
NG or LPG engines are certified to operate on natural or liquid propane gas. The
emissions control system for this engine is EM (Engine Modifications).
WARNING:
with an automatic safety gas "fuel lock-off" valve. Do not operate the equipment if the
"fuel lock-off" valve is missing or inoperative.
How To Add Fuel
°C
When Adding Fuel
Fill fuel tank outdoors or in well-ventilated area.
•
Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.
•
Replace if necessary.
For information on refueling natural or LP gas engines, read the operating instructions
supplied by the equipment manufacturer.
How To Start The Engine - Figure 3
Rapid retraction of starter cord (kickback) will pull hand and arm
toward engine faster than you can let go.
Broken bones, fractures, bruises or sprains could result.
When starting engine, pull the starter cord slowly until resistance is felt and then
•
pull rapidly to avoid kickback.
Remove all external equipment/engine loads before starting engine.
•
Direct-coupled equipment components such as, but not limited to, blades,
•
impellers, pulleys, sprockets, etc., must be securely attached.
When Starting Engine
Ensure that spark plug, muffler, and air cleaner (if equipped) are in place and
•
secured.
Do not crank engine with spark plug removed.
•
Engines give off carbon monoxide, an odorless, colorless, poison gas.
Breathing carbon monoxide can cause nausea, fainting or death.
Start and run engine outdoors.
•
Do not start or run engine in enclosed area, even if doors or windows are open.
•
