•Use low pressure air (not to exceed 25 psi) to blow away dirt. Inspect cooling air slots and opening on water pump. These openings must be kept clean and unobstructed.
Remove silt and sludge buildup in pump body:
•Open priming plug and remove drain plug.
•Flush internal components of pump with clean water.

STARTING TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
*The use of
**The use of SAE 30 oil in temperatures below 40°F (4°C) will result in hard starting and possible engine bore damage due to inadequate lubrication.
NOTE: Synthetic oil meeting ILSAC
Checking Oil Level
Oil level should be checked prior to each use or at least every 8 hours of operation. Keep oil level maintained.
1.Make sure unit is on a level surface.
2.Remove oil fill cap and wipe clean with cloth.
3.Verify oil is at the point of overflowing at oil fill opening.
MAINTENANCE
Adding Engine Oil
1.Make sure unit is on a level surface.
2.Check oil level as described in “Checking Oil Level”.
3.If needed, slowly pour oil into oil fill opening to the point of overflowing at oil fill cap.
Changing Engine Oil
Change the oil after the first 5 hours of operation. Change oil every 50 hours thereafter. If you are using your water pump under extremely dirty or dusty conditions, or in extremely hot weather, change the oil more often.
CAUTION
Avoid prolonged or repeated skin contact with used motor oil.
•Used motor oil has been shown to cause skin cancer in certain laboratory animals.
•Thoroughly wash exposed areas with soap and water.
KEEP OUT OF REACH OF CHILDREN. DON'T POLLUTE. CONSERVE RESOURCES. RETURN USED OIL TO COLLECTION CENTERS.
Change the oil while the engine is still warm from running, as follows:
1.Make sure unit is on a level surface.
2.Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug.
WARNING
Unintentional sparking can result in fire or electric shock.
WHEN ADJUSTING OR MAKING REPAIRS TO YOUR WATER PUMP
•Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug.
WHEN TESTING FOR ENGINE SPARK
•Use approved spark plug tester.
•DO NOT check for spark with spark plug removed.
