Maintenance

Preventive Maintenance 
Schedule

The operating conditions of your particular system 
determine how often maintenance is required. Establish 
a preventive maintenance schedule by recording when 
and what kind of maintenance is needed, and then 
determine a regular schedule for checking your system. 

Tighten Threaded Connections

Before each use, check all hoses for wear or damage. 
Replace as necessary. Check that all threaded connec-
tions are tight and leak-free.

Flushing

Flush the pump:

Before first use

When changing colors or fluids

Before repairing equipment

Before fluid dries or settles out in a dormant pump 
(check the pot life of catalyzed fluids)

At the end of the day

Before storing the pump.

Flush at the lowest pressure possible. Flush with a fluid 
that is compatible with the fluid you are pumping and 
with the wetted parts in your system. Check with your 
fluid manufacturer or supplier for recommended flushing 
fluids and flushing frequency.

1.

Follow Pressure Relief Procedure, page 13.

2.

Remove tip guard and spray tip from gun. Refer to 
separate gun manual.

3.

Place siphon tube in grounded metal pail containing 
cleaning fluid.

4.

Set pump to lowest possible fluid pressure, and start 
pump.

5.

Hold a metal part of the gun firmly to a grounded 
metal pail. 

6.

Trigger gun. Flush system until clear solvent flows 
from gun.

7.

Follow Pressure Relief Procedure, page 13.

8.

Clean the tip guard, spray tip, and fluid filter element 
separately, then reinstall them.

9.

Clean inside and outside of suction tube.

Read all Warnings. Follow all Grounding instruc-
tions. See page 11.
