MAINTENANCE
Risk of severe injury or property damage from fire or projectiles.
• Never start or operate a pump known or suspected to be damaged, defective or malfunctioning.
• Do not make adjustments or repairs to the pump or engine while engine is operating.
• Complete all scheduled maintenance in a timely manner per the manufacturer’s recommendations. Correct any issues before operating
the pump. Improper maintenance will void the pump's warranty.
Preventative maintenance and a pre-operation inspection is to be performed before each use by knowledgeable, experienced owners or certified
service dealers.
A poorly maintained pump can become a safety hazard! For the pump to operate safely and properly throughout its product lifecycle, periodic
maintenance and occasional repairs are necessary.
1. Refer to and follow instructions in the engine manufacturer's owner's manual for recommended engine maintenance.
2. Turn engine off.
3. Allow unit to cool completely.
4. To prevent accidental starting, remove and ground the spark plug wire before performing any service.
5. Check for any loose nuts, bolts, and attachments and retighten as required.
6. Check the engine, pump and its components for damage. If there is visible damage, do not operate the engine or pump! Contact the engine or
pump manufacturer immediately for assistance.
7. Check the engine for oil and/or fuel leaks. If a leak is found, do not operate the engine! Contact the engine manufacturer immediately for assistance.
8. Inspect for water leaks between pump and engine as well as all other sealing interfaces and have serviced as required. If water is leaking, the
seal inside pump is worn or damaged. Continued operation may cause water damage to engine.
9. Inspect motor and pump mounts for damage and replace as required.
10. Clean pump per the “Cleaning the Pump” Section of this manual.
CLEANING
Risk of injury or damage to equipment.
• Do not remove priming plug, drain plug, pump housing or inlet or discharge hose fittings when pump is hot. Hot water and/or vapor
inside could be pressurized.
• Do not spray engine with water. Water can contaminate the fuel system.
Clean inside of pump housing after every use.
1. Allow the unit to cool completely.
2. After the unit has cooled, remove drain plug and priming plug from pump housing and drain any water left in the pump.
3. Remove the (4) bolts securing the pump housing and save for reuse. Remove pump housing.
4. Remove volute insert.
5. Clean out dirt and debris.
6. Inspect impeller and volute insert for wear. The impeller may develop sharp edges after use. Use care when cleaning around impeller to avoid
getting cut. Replace impeller and/or volute insert if wear is significant.
7. After cleaning, inspection and replacements if necessary, reinstall the volute insert, pump housing (using bolts removed earlier), drain plug
and priming plug.
