• Fuel mixture is 24:1 – 1 litre of oil – 22 litres (5 gal) gas

• Require at least 8'' of water to cover the foot valve

• Drawing in sand, gravel or debris can damage the pump impellers

• Intake & pump end requires priming or engine will rev up and quit

• Do not run at full throttle until the engine is warmed up at least 2 minutes

• Before stopping, move throttle lever to ‘stop’. Let idle for a minute before pushing stop switch

• Releasing the stop switch too soon (before engine quits can cause a backfire (& damage)
