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. 
Your maintenance schedule should include the follow-
ing:

Flushing

Flush before changing colors, before fluid can dry in 
the equipment, at the end of the day, before storing, 
and before repairing equipment.

Flush at the lowest pressure possible. Check con-
nectors for leaks and tighten as necessary.

Flush with a fluid that is compatible with the fluid 
being dispensed and the equipment wetted parts.

Mix Tank Volume

Don't let the mix tank run dry. When the tank is empty, 
the pump demands more power as it tries to suck in 
some fluid. This causes the pump to run too fast, which 
can seriously damage the pump.

Hydraulic Power Supply Check

Carefully follow the hydraulic power supply manufac-
turer's recommendations on reservoir and filter cleaning, 
and periodic changes of hydraulic fluid.

Stall Test

Perform a stall test periodically to ensure the piston seal 
is in good working condition and prevent system over-
pressurization:

Close the fluid shutoff valve (D) closest to the pump on 
the downstroke and be sure that the pump stalls. Open 
the fluid shutoff valve to restart the pump. Close the fluid 
shutoff valve (D) closest to the pump on the upstroke 
and be sure that the pump stalls.

Stop the pump on the downstroke, before the air motor 
changes over.

NOTICE

Do not allow the pump to run quickly for a long period 
of time as this may damage the packings.

NOTICE

Failure to stop the pump at the bottom of its stroke 
allows fluid to dry on the piston rod, which can dam-
age the throat packings and the TSL pump piston seal 
when the pump is restarted.
