COMPRESSED AIR PUMP ASSEMBLY
Refer to the Air Fuel Ratio Module and AFR-4 Pump Assembly Installation and User
Guide (P/N 98200006) for proper operating and maintenance procedures. Refer to
the Flow Meter User Guide (P/N 98129104) to test your air pump for accuracy. Failure
to follow proper procedures may result in inaccurate data or damage to the
equipment. These manuals can be found on your WinPEP CD or at www.dynojet.com.
The sensor and the copper sample tube are hot. Before touching the sensor or
the sample tube, make sure it has cooled.
Leaded racing fuels and two-stroke applications will contaminate the sensor
and dramatically shorten its service life.
The sensor is not covered by a warranty. Be sure to read and understand the Air
Fuel Ratio Module and AFR-4 Pump Assembly Installation and User manual.
Before turning the pump on, verify there is no water in the hose.
Warm up the vehicle before placing the copper sample tube in the exhaust to
avoid drawing excess water through the pump assembly.
Keep the air pump assembly upright. Tipping the pump assembly may result in
damage to the sensor.
Leaks in the system will result in erroneous readings. Verify there are no cracks
or holes in the hose. Verify the sensor is seated properly in the sensor block.
To ensure accurate readings, pump maintenance should be performed every
six months, or sooner, depending on usage. Refer to the Air Fuel Ratio Module
and AFR-4 Pump Assembly Installation and User Guide for more information.
