1. Remove LPG fuel injector from carburetor.
CAUTION
Be careful not to damage the injection orifice
or the inner parts of the injector while clean-
ing. Do not insert the steel wire in the injection
nozzle more than 20 mm (0.79 in.).
2. Check injection nozzle for carbon or other de-
posits. If there are any deposits, clean outside
of nozzle. Then insert a small steel wire [1.2 mm
(0.05 in.) maximum diameter] into nozzle in or-
der to remove any deposits inside nozzle.
3. After cleaning, apply 350 to 500 kPa (51 to 73 psi)

OXYGEN SENSOR, GM 3.0L EPA
COMPLIANT ENGINE
NOTE: Make sure connections are air tight. If these
connections are not air tight, incorrect oxygen read-
ings could be entered into the fuel air ratio.
CAUTION
Do not use silicone spray or silicone based
products on the oxygen sensor. Use of silicone
products can cause severe damage to the oxy-
gen sensor.
Check that the oxygen sensor electrical connector is
seated and locked. Check wires for cracks, splits,
chaffing, or burn through. If necessary, repair.
AIR FILTER ELEMENT, GM 3.0L EPA
COMPLIANT ENGINE
NOTE:
In dirty or dusty environments, change at
1000 hours.
Replace the air filter element after 2000 hours.
INSPECT LOW PRESSURE REGULATOR
(LPR) FOR OIL BUILDUP AND LEAKS
CAUTION
The Low Pressure Regulator (LPR) has been
designed for the GM 3.0L EPA Compliant En-
gine. The regulator should not be disassembled
or rebuilt. If the LPR fails to operate or has a
leak, the LPR should be replaced with ONLY
recommended HYSTER replacement parts.
To check the LPR, perform the following checks:
• Check for fuel leaks at the inlet fitting, outlet fit-
ting, and regulator body.
• Check the inlet and outlet fittings of the coolant
supply for water leaks.
• Check the coolant lines for hardening, cracking,
chaffing or splits. Replace if needed.
• Check coolant supply hose clamp connections,
make sure they are tight.
