IMPORTANT SAFETY INFORMATION
Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in serious injury.
Save all warnings and instructions for future reference.
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Stay alert, watch what you are doing and
use common sense when assembling the
Wheel Kit. Do not assemble while you are
tired or under the influence of drugs, alcohol
or medication. A moment of inattention
may result in serious personal injury.
3. Use personal protective equipment. Always wear
eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat,
or hearing protection used for appropriate
conditions will reduce personal injuries.
4. Dress properly. Do not wear loose clothing or
jewelry. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewelry
or long hair can be caught in moving parts.
5. Turn off and allow water pump to cool
completely before assembling the
Wheel Kit onto a water pump.
6. Support the water pump on a raised platform so
that the Wheels and feet can easily be attached.
7. Assemble wheel kit completely before
attempting to use water pump. Do not
partially install kit, or use only part of the kit.
8. Do not roll water pump on uneven
surfaces, or on inclines.

if parts loose, bent, or damaged.
10. Turn off before moving water pump. Do not
move water pump while in operation or hot.
11. Secure water pump properly before
transporting on a vehicle.
12. Maintain labels and nameplates on the tool.
These carry important safety information.
