Maintenance

Fill the wet-cup (P) 1/2 full of Graco Throat Seal Liquid (TSL) or compatible solvent and keep it 1/2 full to keep fluid from drying on the displacement rod and damag- ing pump throat packings. See Fig. 5.

Lubricate the throat packings frequently when you are pumping a non-lubricating fluid, or are shutting down for more than a few days. Some pumps have a grease fitting (DD) for this purpose. See Fig. 5.

The accessory air line lubricator (C) provides automat- ic air motor lubrication. To manually lubricate the mo- tor, disconnect the air line at the air motor inlet, put about 15 drops of lightweight oil in the inlet, reconnect the air line and turn on the air to blow oil into the motor.

Never allow the pump to run dry of fluid being pumped. A dry pump will quickly accelerate to a high speed, possibly damaging itself. If your pump accelerates quickly, or is running too fast, stop it immediately and check the fluid supply. If the supply container is empty and air has been pumped into the lines, prime the pump and lines with fluid, or flush and leave filled with compatible solvent. Be sure to eliminate all air from the fluid system.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure on page 8.

WARNING

Do not attempt to adjust the packing nut with the pump operating.

Periodically, check the tightness of the packing nut (P). Relieve the pressure, then tighten enough to prevent leakage; no tighter. See Fig. 5. If the leakage can not be stopped, change the packings to prevent exposure to the fluid being pumped.
