Setup; Wet Cup; Flush The Pump - Graco Check-Mate 100 Instructions And Parts

Setup

Wet Cup

Before starting, fill the wet cup (H) 1/3 full with Graco
Throat Seal Liquid (TSL) or a compatible solvent.
NOTE: The enclosed wet cup has a fill port in the cover.
Torque the Wet Cup
The wet cup is torqued at the factory; however, throat
packing seals on Severe Duty pumps may relax over
time. Check wet cup torque frequently after initial
start-up and periodically after the first week of produc-
tion. Maintaining proper wet cup torque is important to
extending seal life.
NOTE: MaxLife pumps use a special u-cup throat seal
that is non-adjustable and does not require periodic
torquing.
1. Follow the Pressure Relief Procedure on page 14.
2. Torque the wet cup (H) using the packing nut
wrench (supplied) whenever necessary. Do not
overtighten the wet cup. See the table below for
torque values.

Flush the Pump

To avoid fire and explosion, always ground the equip-
ment and the waste container. To avoid static spark-
ing and injury from splashing, always flush at the
lowest possible pressure.
NOTE: The pump is tested with lightweight oil, which is
left in to protect the pump parts. If the fluid you are using
may be contaminated by the oil, flush it out with a com-
patible solvent before using the pump.
Always flush at the lowest pressure possible. Check
connectors for leaks and tighten as necessary. Flush
with a fluid that is compatible with the fluid being dis-
pensed and the equipment wetted parts.
NOTE: Check with your fluid manufacturer or supplier
for recommended flushing fluids and flushing frequency.
Never leave water or water-based fluid in a carbon
steel pump overnight. If you are pumping a
water-based fluid, flush with water first. Then flush
with a rust inhibitor, such as mineral spirits. Relieve
pressure, but leave the rust inhibitor in the pump to
protect parts from corrosion.
1. Follow the Pressure Relief Procedure on page 14.
2. Remove the spray tip/nozzle from the gun/valve and
soak in solvent.
3. Place the material supply suction hose into compati-
ble solvent.
4. Start the pump and use the pressure adjustment
knob (K) to adjust pressure. See Start and Adjust
the Pump on page 12.
5. Hold a metal part of the gun/valve firmly to the side
of a grounded metal pail.
6. Trigger the gun/valve and flush the system until
clear solvent flows from the gun/valve.
7. Follow the Pressure Relief Procedure on page 14.
