ARROW PRODUCT OVERVIEW
An easy, inexpensive way to reduce production costs on pumping wells is to properly maintain the pumping engine. Both the slow speed single and twin cylinder type engines are designed to operate unattended, continuously, for weeks at a time. However, periodic preventive maintenance will extend the life of the engines by two to three times, and substantially reduce repair costs.
Ignition systems head the list of recommendations for complete engine check-ups. Because more production hours are lost due to moisture in the ignition system than any other reason, an adequate cover should be provided to keep rain and moisture off the magneto, or alternator, if a breakerless ignition system is used. Wires should be inspected for cracks in insulation; and connections should be tight and solid. On shielded or low-tension systems, ignition coils should be mounted with the spark plug connections pointed down so they do not collect moisture.
