Using the GP - 2 Slim Dual Component Pump is easy. First, choose your power source, either the standard 115V AC or the optional 24V DC. Then, fill the two 6.4 - gallon stainless steel tanks with your polyurea or epoxy. Attach the static mixing tips and adjust the dispensing wand to a comfortable position. When you're ready, start the motor and begin applying the material. Remember, the wand has no 90 - degree angles for better flow. When you're done, mount the wand on the no drip mount. As for maintenance, keep the powder - coated steel frame clean. Check the hoses regularly for any signs of wear. If you use the optional generator, make sure to maintain it according to the manufacturer's instructions. And always store the pump in a dry place.
