6 MAINTENANCE

6.1 Daily Maintenance

Nozzle
Figure 6-1
DO NOT use lacquer thinner (MEK). Cleaning the colorant from the nozzle seal pad will
lessen the possibility of mis-tints caused by the collection of colorant. Large accumulations
of colorant on the seal arm/pad may be caused by a malfunction of the automatic drip
control piston.

6.2 Periodic Maintenance

When the machine is not being used on a regular daily base, the following procedures
should be carried out.
1) Check the level of colorant and top up if required.
2) Open and close each Valve Handle five times.
3) Set gauge to the maximum 3Y and stroke the plunger handle up and down three times
without opening the Valve Handle.
4) Check Valve Handle and nozzle Seal Arms/Tips for possible damage, and clean thoroughly.
5) Dispense colorant into a paper cup and return to canister. Constant movement of colorant is
required to prevent hardening of colorant in nozzle and valve assembly.
Colorants are heavy bodied fluids containing particle of pigment. During the plunger operation, a
slight amount of colorant may stick to the cylinder wall, which after a period of time, may cause
drag or stiffness in the operation of the plunger. A small amount of stiffness should cause no
concern. If the stiffness of operation becomes difficult, complete replacement of pump will be
required.
Keeping the Nozzle and Tip Seal clean and free
of dried, dripping or collecting colorant is
essential for trouble-free dispensing.
It is recommended the Nozzle and Seal Tip be
cleaned daily with a moist cloth: water or
mineral spirits is satisfactory.
