(1) Verify that the seal on the engine fuel injector is in place and that the proper fuel pump is on the equipment.

(2) Install a new clean intake air cleaner, measure and record the intake restriction pressure.

(3) Check the level of engine oil.

(4) Change the engine lubrication oil if not fresh.

(5) Check the level of the transmission fluid.

(6) Measure and record the exhaust backpressure. If exhaust gas back pressure is above that recommended by the manufacturer, steps must be taken to bring the exhaust gas back pressure within the manufacturer's recommended limit prior to beginning the test described in this subsection.

(7) Test the brakes.

(8) Place the equipment into an intake entry.

(9) Set the brakes and chock the wheels.

(10) Install an exhaust gas analyzer into the untreated exhaust gas port.

(11) Start the engine and allow it to warm up to operating temperature.

(12) Put the engine into a loaded condition. For this section, the loaded condition for the baseline emissions testing shall be determined by the technical advisory committee by determining CO2 values that are representative of the MSHA lug curve readings for that engine model and horsepower.

(13) Start the exhaust gas analyzer and allow the engine to operate in the loaded condition for a sufficient length of time not less than a 90-second duration to insure proper CO readings. The qualified mechanic shall record both CO and CO2 readings. Note: Baseline CO values shall be determined by the technical advisory committee based upon MSHA lug curve readings for that engine model and horsepower. If the baseline CO values are greater than the MSHA lug curve values, the technical advisory committee shall investigate and either recommend approval or disapproval or recommend alternate methods of meeting the requirements of this section.

(14) Comply with recordkeeping requirements pursuant to section 414.²

(15) An alternative to the testing provided in paragraphs (1) through (14) may be developed by the technical advisory committee in accordance with section 424.

(16) Emissions test procedures for this section shall be submitted to the technical advisory committee in accordance with section 424 prior to being implemented for each engine and equipment type.
