OPERATION PRECAUTIONS
1. Do not operate pump in an explosive environment. Arcing from
the motor brushes, switch or excessive heat from an improperly
cycled motor may cause an explosion.
2.
Do not pump gasoline or other flammable liquids.
3.
Do not assume fluid compatibility. If the fluid is improperly
matched to the pumps’ elastomers, a leak may occur.
4.
Intermittent duty is defined as operation and/or frequent starting
within a period of time that would cause the motor to reach its
maximum thermal limits.
Once the maximum is obtained, the motor must be allowed to return
to ambient temperature before resuming operation.

IMPORTANT RETURN SAFETY INSTRUCTIONS
When you return your pump for warranty or repair, you must always do
the following:
1.
Flush chemical residue from the pump (best done in the field).
2. Tag pump with type of chemicals having been sprayed.
3. Include complete description of operation problem, such as how
pump was used, symptoms of malfunction, etc.
Since pumps can contain residues of toxic chemicals these steps are
necessary to protect all the people who handle return shipments, and
to help pinpoint the reason for the breakdown
