The following information is to be considered as a general outline for installation. If you have unique requirements, please contact Giant Industries, Inc. or your local distributor for assistance. 1. The pump should be installed flat on a base to a maximum of a 15 degree angle of inclination to ensure optimum lubrication. 2. The inlet to the pump should be sized for the flow rate of the pump with no unnecessary restrictions that can cause cavitation. Teflon tape should be used to seal all joi

To release tension beforehand, strike the plugs 1 to 2 times with a steel hammer on the top (before removing them). When replacing them, make sure that the threads are coated with antiseize, e.g., ProPack550. To Check Suction and Discharge Valves Inlet Valves 1. Using a socket wrench, carefully remove valve plugs (41 and 43). Take out the suction valve adaptor (39) along with the suction valve assembly (34-38). 2. Using a soft tool, push the valve assembly (34-38) out of the suction valve adapto

But, if it is used carelessly and without regard to its potential hazard, it can cause serious injury. IMPORTANT OPERATING CONDITIONS Failure to comply with any of these conditions invalidates the warranty. 1. Prior to initial operation, add oil to the crankcase so that oil level is between the two lines on the oil dipstick. DO NOT OVERFILL. Use Giant recommened Oil Crankcase oil should be changed after the first 50 hours of operation, then at regular intervals of 500 hours or less dependin
