Operating Instructions
Fuel Systems
rR
ep
The fuel system installed on your engine operates with an Electronic Pressure Regulator (EPR) and a
diaphragm style variable venturi mixer. The EPR will regulate the fuel pressure being delivered to the
mixer; these parts are not adjustable and should not be tampered with. Proper inlet fuel pressure is
critical to the proper operation of the fuel system and engine; you should the review the pressure,
volume, and BTU recommendations prior to commissioning the engine.
Governors
ot
fo
PSI engines have an isochronous governor installed. The governor controls the movement of the
throttle plate via a 0-12 volt signal and a ground provided by the Engine Control Module. The
throttle plate allows the correct amount of air to enter the engine; this movement is monitored by
using 2 throttle position sensors located internal to the governor. The ECM monitors various engine
sensors to determine what the correct throttle position should be.
N
Oil Pressure Reading
The oil pressure reading shows the engine lubrication system pressure in pounds per square inch
(psi) and should be checked frequently to ensure that the system is functioning correctly. Should the
pressure fluctuate or drop, stop the engine and find the cause. Do not operate the engine at lower than
normal oil pressure (see maintenance schedule for minimum engine oil pressure).
5
Operation and Maintenance Manual
Certified Stationary Product
CAUTION: Do not continue to operate your engine below the normal operating range. Severe
engine damage could occur.
Temperature Reading
The coolant temperature reading will indicate overheating which may arise from low coolant level,
plugged radiator, loose fan belt or faulty thermostat. Coolant level should be checked daily.
Voltage Reading
ro
du
ct
io
n
CAUTION: If the engine continues to overheat, have the cooling system checked and serviced.
The voltage reading indicates the battery charging voltage. If the meter consistently indicates less than
13 volts or more than 15.7 volts under normal operating conditions, you should have the engine
electrical system checked by a qualified service technician.
Tachometer/Hourmeter
rR
ep
The tachometer indicates the engine speed in hundreds of revolutions per minute (rpm). It serves, as a
guide to insure that engine speed is set correctly.
The hour meter records the hours of operation and is used to determine when periodic maintenance is
required.
fo
Starting the Engine
ot
Warning: All internal combustion engines give off various fumes and gases while running. Do not
start or run the engine in a closed or poorly ventilated building where exhaust gases can accumulate.
Avoid breathing these gases as they may contain poisonous carbon monoxide, which can endanger
your health or life if inhaled steadily for even a few minutes.
N
If the engine is equipped with a manual clutch it must be disengaged prior to starting the engine.
Starting the engine with the clutch engaged imposes unnecessary strain on the battery, starter, and
driven components.
CAUTION: If the engine stalls or falters during starting, wait 3 to 4 seconds before re-engaging the
starter. This will prevent possible damage to the starter or the engine. DO NOT operate the starter for
periods longer than 30 seconds at a time. An interval of at least 1-minute should be observed between
cranking periods to protect the starter from overheating.

LPG or NG Fuel Systems
Turn on the gas supply to the engine. Turn the ignition key to the START position. After the engine
starts release the key to the ON position.
Stopping the Engine
ro
du
ct
io
n
Return the engine to idle speed. If the machine is equipped with a clutch, move the clutch lever to
the disengaged position. Run engine for a few minutes at idle to allow the coolant system to cool
down before turning the ignition switch to the OFF position.
Note: Gasoline fuel injected engines will generally shut off immediately when the key is switched to
the off position. When the key is switched off, power to the fuel injector(s), fuel pump and engine
control module (ECM) is removed.
rR
ep
Note: LPG engines equipped with a distributorless ignition system (DIS) may run on several seconds
after the key is switched to the off position. This may be a normal function of the engine control
system running fuel out of the vapor hose to prevent engine backfiring on restart. The engine may run
up to 5 seconds after the key is switched to off. Check with the Equipment Manufacture for proper
shut down operation.
WARNING: Avoid injury when checking a Hot Engine. Allow the engine to cool down before
removing the radiator cap.
CAUTION: Before restarting the engine ensure that both the coolant system and the engine oil level
have been checked and re-filled if necessary.
Fuel Quality
fo
Fuel Recommendations
N
ot
PSI NG engines are designed to operate on pipeline quality natural gas with a heat value of 1050 BTU
or higher. LPG engines and fuel systems are designed to operate on HD-5 or HD-10 specification LPG
fuel. Fuel other than HD-5 or HD-10 may cause harm to the engine’s emission control system and a
warranty claim may be denied on this basis if operators can readily find the proper fuel. Use of any
other fuel may result in your engine no longer operating in compliance with CARB or EPA emissions
requirements.

Spark plugs
n
Always use the recommended spark plugs for your engine. Hotter or colder plugs, or similar plugs
that are not exact equivalents to the recommended plugs, can cause permanent engine damage,
reduce the engines useful life, and cause many other problems such as hard starting, spark knock and
run-on. Installing new spark plugs regularly is one of the best ways to keep your engine at peak
performance.
ro
du
ct
io
Power Loss at Higher Elevations
All engines will experience power loss when operated at elevations above sea level, unless they
are turbocharged or supercharged. Turbochargers and superchargers are mechanical pumps that
put extra air into the engine to make up for the lower air density at higher elevations.
MAINTENANCE INSTRUCTIONS
rR
ep
Initial Start Up Maintenance
The initial start-up checks must be made before putting the engine into service. Please refer to the
Maintenance Schedule and perform the initial start-up operations in the sequence shown in column 1.
Routine Maintenance
fo
Routine maintenance provides the best solution for making sure that the engine is ready when you are.
The following are some routine service points:
N
ot
Make daily checks of the engine oil and coolant levels
Repair any oil or coolant leaks immediately
Check battery condition and cables frequently
Keep the engine air filter clean
Monitor engine coolant temperature
Monitor engine oil pressure
Check voltmeter and charging system
Scheduled Preventive Maintenance
Refer to the Maintenance Schedule to ensure that all of the maintenance items listed are checked and
replaced as recommended at the hours shown.

Operation and Maintenance Manual
Certified Stationary Product
Engine Oil Level Check
The engine oil level should be checked daily. It is recommended that the oil be checked just before
the engine is started for the first time for that day. The oil level should be between the ‘Add’ and the
‘Full’ marks on the dipstick.
Adding Engine Oil
ro
du
ct
io
n
CAUTION: Do not operate the engine with the oil level below the bottom or ‘Add’ mark on the
dipstick, or above the top or ‘Full’ mark on the dipstick.
It is normal to add some oil in the period of time between oil changes. The amount will vary with the
severity of operation. When adding or replacing engine oil, be sure the oil meets or exceeds the
recommended specification.
Changing Engine Oil and Filter
rR
ep
The engine oil and filter must be changed every 150 hours or every 3 months whichever occurs first.
Under normal operating conditions, you do not need to change them more often if you use oil and
filters of the recommended quality.
The oil and filter should be changed more often if the engine is operating in dusty or extremely dirty
areas, or during cold weather. No oil additives or break-in oil change is required.
Engine Oil Quality
fo
To achieve proper engine performance and durability, it is important that you use only engine
lubricating oils of the correct quality in your engine. Proper quality oils also provide maximum
efficiency for crankcase ventilation systems, which reduces pollution.
N
ot
Important: use only engine oils displaying the American Petroleum Institute (API) “Starburst”
Certification Mark ‘FOR GASOLINE ENGINES’ on the container.
9
Operation and Maintenance Manual
Certified Stationary Product
PSI recommends using engine oils that have an API rating of SM or newer. Gasoline engines that are
converted for LPG or NG fuels MUST use oils labeled ‘FOR GASOLINE ENGINES’. Do not use oils
that are specifically formulated for Diesel Engines only. CC or CD classifications oils, even when
labeled Heavy Duty or for Natural Gas Engines, ARE NOT ACCEPTABLE.
n
Engine Oil Recommendation
ro
du
ct
io
Multi-viscosity oils are recommended. SAE 10W-30 is recommended for your engine from 0
degrees F (-18 degrees C) or above. If ambient temperatures are consistently below 0 degrees F,
SAE 5W-30 oil can be used. Synthetic oils are not required for industrial or stationary engines.
Oil Filter
The filter protects your engine from harmful, abrasive, or sludgy particles without blocking the
flow of oil to vital engine parts.
To replace the filter, use a proper filter wrench to remove the filter.
Engine Air Cleaner
rR
ep
Clean the filter mounting base and lightly coat the gasket surface of the new filter with engine oil.
Hand tighten the filter until the gasket contacts the base, then tighten another ½ turn. Fill the engine
with the correct amount of oil and run the engine. Verify oil pressure is okay and check for oil leaks
at the drain plug and oil filter gasket. Tighten as necessary to stop any oil leakage noted.
ot
fo
The engine air cleaner filters air entering the engine intake system and acts as a silencer and flame
arrester when assembled to the intake system. Air that contains dirt and grit produces an abrasive fuel
mixture and can cause severe damage to the cylinder walls and piston rings. Damage to the cylinder
walls and piston rings will cause high oil consumption and shorten engine life. A restricted or dirty air
cleaner will also cause a rich fuel mixture. Thus, it is extremely important that the air cleaner be
serviced properly at the recommended intervals.
N
CAUTION: Service the air cleaner more frequently under severe dusty or dirty conditions.
Remove the primary air cleaner element from the air cleaner assembly and inspect the element for
foreign material restrictions or signs of excessive wear or damage. Replace the element if necessary.
Remove all dust and foreign matter from the air cleaner housing. Reinstall the air cleaner element.
Reinstall the air cleaner cup, and securely fasten the retaining clips.

Safety Element
If your engine is equipped with an air cleaner which utilizes a safety element, ensure that the
element is properly in place before installing the primary element.
n
Change the safety element annually.
ro

ct
io
Cooling System
Coolant Level
Check the coolant level of the radiator daily and only when the engine is cool. Generally a good time
to do this is just prior to starting the engine for the first time each day.
rR
ep
Maintain the coolant level at ¾ to 1½ inches below the filler neck seat of the radiator when the coolant
is cold. When ever coolant level checks are made inspect the condition of the radiator cap rubber seal.
Make sure it is clean and free of any dirt particles which would keep it from seating on the filler neck
seat. Rinse off with clean water if necessary. Also make sure that the filler neck seat is free of any dirt
particles.
fo
WARNING: Never remove the radiator cap under any conditions while the engine is operating.
Failure to follow these instructions could result in damage to the cooling system, engine, or cause
personal injury. To avoid having scalding hot coolant or steam blow out of the radiator, use extreme
caution when removing the radiator cap from a hot radiator. If possible, wait until the engine has
cooled, then wrap a thick cloth around the radiator cap and turn slowly to the first stop. Step back
while the pressure is released from the cooling system. When all the pressure has been released, press
down on the cap and remove it slowly.
DO NOT add coolant to any engine that has become overheated until the engine cools. Adding
coolant to an extremely hot engine can result in a cracked block or cylinder head.
N
ot
The engine manufacturer recommends the cooling system be filled with a 50/50 mixture of coolant and
water. The use of “Long Life” type coolant is required. This coolant is typically a bright orange in
color and should meet the requirements outlined in engineering standard GM6277M (hard copy
of GM6277M is available by contacting PSI Technical Support). Coolant should have a minimum
boiling point of 300F (149c) and a freezing point no higher than -34F (-37c).
Plain water may be used in an emergency (except in freezing temperatures), but replace it with the
specified coolant as quickly as possible to avoid damage to the system.
11
Operation and Maintenance Manual
Certified Stationary Product
Radiator
Inspect the exterior of the radiator for obstructions. Remove all bugs, dirt or foreign material with a
soft brush or cloth. Use care to avoid damaging the core fins. If available, use low pressure
compressed air or a stream of water in the opposite direction of the normal air flow. Check all hoses
and connections for leaks. If any of the hoses are cracked, frayed, or feel spongy, they must be
replaced.
n
Fan Belts
ro
du
ct
io
The water pump is belt driven. The same belt may also drive the fan and/or the alternator. The drive
belts should be properly adjusted at all times. A loose belt can cause improper alternator, fan and
water pump operation, in addition to overheating.
Serpentine Belt
Some PSI engines utilize serpentine belts on the front of the engine. This type of belt system incorporates a belt tensioning device which keeps the belt at the proper tension.
rR
ep
This belt should be checked routinely for cracks or ‘checking’ on the groove side of the belt. If cracks
or ‘checking’ are apparent the belt must be changed.
V-Type Belt
Fuel Filter
fo
V-Type belts are generally tensioned by adjusting the
alternator, or through a mechanical belt tensioner. The belt is
generally correctly tensioned when there is 7-10mm of
deflection on the belt between the water pump and alternator.
ot
LPG Engines
N
LP, fuel like all other motor fuels is subject to contamination from outside sources. Refueling of the
equipment tank and removal of the tank from the equipment can inadvertently introduce dirt and other
foreign matter into the fuel system. It is therefore necessary to filter the fuel prior to entering the fuel
system components down stream of the tank. An inline fuel filter has been installed in the fuel system
to remove the dirt and foreign matter from the fuel, which is replaceable as a unit only. Maintenance
of the filter is critical to proper operation of the fuel system and should be replaced according to the
maintenance schedule or more frequently under severe operating conditions.
12
Operation and Maintenance Manual
Certified Stationary Product
Fuel Shut-Off
LPG and NG engines are equipped with a fuel shut-off. The fuel shut-off is located between the fuel
supply and the IEPR/DEPR. The purpose of the fuel shut off is to prevent or allow fuel flow from the
supply source to the engine fuel system. The shut off is a 12 volt solenoid (Normally closed) that is
controlled by the engine ECM.
Types of Ignition Systems
ro
du
ct
io
n
Ignition Systems
PSI engines use two types of ignition systems. 1) Distributor-less electronic ignition and 2) High
Voltage Switch (HVS) ignition. Both types of ignition are controlled by the engine ECU.
Distributor-less electronic ignition is utilized on the 1.6L, 8.1L, and 8.8L engines. All other engine
models use a HVS ignition system which consists of a distributor and HVS ignition coil.
Ignition Timing
rR
ep
Proper adjustment of the ignition timing must be obtained to provide the optimum engine power
output and economy. Ignition timing for both the Distributor-less and HVS systems are controlled
by the ECU and is not adjustable.
NOTE: Do not attempt to adjust timing on the ignition systems. Timing is not adjustable.
Spark Plugs
fo
Spark plugs should be replaced at the recommended intervals described in the Maintenance Schedule.
Use only the recommended spark plug or an equivalent as described in the General Specifications.
Spark plug gap should be adjusted as recommended in the General Specifications.
N
ot
When removing spark plugs, always note which cylinder each plug came out of. Look at the porcelain
around the center electrode of each plug. You can detect many engine problems from the color and
type of deposits that have built up on the white porcelain. For example, if the deposits are a glossy
brown, that cylinder is burning excess oil. If the deposits are a very dark gray or sooty black color,
your engine is running rich, and you are burning excess fuel. The optimum color of the deposits on the
porcelain is light tan or light brown. This shows optimum fuel mixture and proper engine running
conditions. If the deposits are almost white, the engine may be running excessively lean.
Lean running is very detrimental to your engine life, and should be corrected immediately. If one or
more cylinders are burning oil, the smoke from the engine will be a blue-gray color. Most common
causes are piston rings (worn out or not broken in) and valve stem seals (cut, nicked, or worn out). If
13
