MaintenanceofEquipment

Warning: The proper maintenance of equipment is vital to safe operation. LPG engines are dependent on engine tune up, and air filter replacement. CO concentration (production) skyrockets when the air to fuel ratio becomes fuel rich. Follow the recommended Maintenance Schedule for the engine found in the Engine Operator/Owner Manual as well as the Maintenance And Adjustments schedule found in the Propane Floor Equipment Operator’s Manual that were supplied with the equipment. Additional manuals may be obtained by contacting Clarke at 1-800-545-3454 or write to Clarke Customer Service, 2100 Hwy. 265, Springdale AR 72764.
