DANGER !

Before opening any Viking pump liquid cham-

ber (pumping chamber, reservoir, relief valve

adjusting cap fitting etc.) Be sure:

1. That any pressure in the chamber has been

completely vented through the suction or

discharge lines or other appropriate openings

or connections.

2. That the driving means (motor, power takeoff,

turbine, engine, etc.) has been “locked out”

or made non- operational so that it cannot be

started while work is being done on pump.

3. That you know what liquid the pump has been

handling and the precautions necessary to

safely handle the liquid. Obtain a material

safety data sheet (MSDS) for the liquid to be

sure these precautions are understood.

Failure to follow above listed precaution-

ary measures may result in serious injury or

death.
