4PRIMING THE MACHINE
With the unit assembled and canisters mounted, the following steps should be carried out to
ensure that your machine is properly prepared for accurate and trouble-free dispensing.
The canisters have a capacity of 3.17 Quarts and it is recommended that only one quart of
colorant be used on the initial filling. Additional colorant can be added once proper operation is
achieved.
Figure 4-1 Figure 4-2 Figure 4-3
1) Place each can of colorant into a mixer or shaker for approximately 5 minutes (or as specified
by the colorant manufacturer) to mix any settled pigment.
2) Remove canister lids.
3) Pour the contents of each can of colorant into individual canisters.
4) Set the gauge (Ref. # 2) of each pump to the 3Y or 100 ml setting, by depressing the spring
loaded button (Ref. # 3) and lifting the gauge by its handle.
5) Prime each cylinder by lifting up the plunger handle (Ref. # 1) to its maximum travel, and
pressing the plunger handle downward fully, WITHOUT OPENING THE VALVE HANDLE!
Repeat this process 5-6 times: this draws colorant from the canister into the cylinder and
purges the air from the system.
6) Lift the plunger handle to its maximum travel. Place a clean can or paper cup under the
dispense nozzle (Ref. # 5). Open the discharge valve by turning the valve Handle (Ref. # 4)
in a clockwise direction until it locks into place. Push the plunger handle down fully to
dispense colorant into the cup. Return the valve Handle to the closed position by pressing the
release button (Ref. # 6). Repeat this procedure until the colorant emerges as an unbroken
stream.
7) Once the cylinder is free of air, repeat steps 4 and 5 for all remaining canisters. Return all
dispensed colorant to its respective canisters. Your machine is now ready for use!
Do not add colorant when agitation is taking place.

5TINTING INSTRUCTIONS
5.1 Dispensing from the cylinder
1) With the plunger set at the required measurement and the cylinder full, turn the spring
loaded valve handle (Ref. # 2) clockwise until it locks into position.
2) Push the plunger handle (Ref. # 1) down completely, in a smooth even motion.
3) Your full dispense is now complete.
4) Return the valve handle to the closed position by pressing the release button (Ref. # 3).
5) Repeat the charging and discharging process for the required strokes (total formula).
Continue with the next required colour.
6) When the entire paint order is complete, gently lower gauges to zero position.
DO NOT push gauge release button and allow gauges to drop down.
Lower manually to avoid damage.
Handle # 2 Dispense Position Handle # 2 Closed Position
Figure 5-1 Figure 5-2 Figure 5-3
5.2 Automatic drip control piston
Activation of the Automatic Drip Control Piston provides a small suction of air to clean the
dispense nozzle of any remaining colorant and ensures clean dispensing ports and greater
accuracy. The valve automatically works on each dispense.
5.3 Tinting instructions
1) Identify the colour you wish to supply, either by name or code number.
2) Refer to your color formula reference book for the tint formula and note the tint base
required.
3) Determine the formula required for the size of paint can being tinted.
Plunger Handle # 1

4) Ensure all gauges are set to zero before beginning.
5) Place the open can of paint under the dispensing nozzle. Unlock the Carousel Index Lever and
rotate the turntable until the appropriate canister is directly over the can of paint, and lock
the Carousel Index Lever. If a formula which cannot be measured in one dispense is required,
multiple dispenses will be necessary. It is always best to divide a formula into equal
dispenses.
6) Set the Gauge by pressing the Gauge Locking Button (Ref. # 3) and raising the Gauge until
the desired measurement appears beneath the arrow in the window at the top of the Plunger
Handle (Ref. #1).
7) To add smaller increments than the main gauge allows, turn the Smart Gauge handle located
on the piston handle in a clockwise direction, until the desired increment appears in line with
the arrow in the window.
8) With the gauge correctly set, slowly and gently lift the plunger handle until it reaches the
gauge handle. Continue to hold for a few seconds to ensure that the cylinder has completely
filled with colorant.
It is always best to divide the required formula into equal dispenses, even if it requires more
dispenses than what might otherwise be required. Mis-tints are generally caused by operator error
in setting the gauges. The fewer changes in the gauge settings, the lower the chances of errors.
9) Turn the handle 90 degrees clockwise to the dispense position until it locks into position. En-
sure a can is in position under the nozzle.
10) Press the plunger handle down to dispense the colorant. Ensure the plunger handle is
pressed down fully.
11) Press the button on the handle firmly and the handle should automatically rotate 90 degrees
anticlockwise and return to the close position.
Figure 5-4
DO NOT open or operate the dispensing Valve Handle while charging the cylinder.
If the valve handle is opened, even the slightest amount, air will be drawn into the cylinder
chamber resulting in an inaccurate dispense. If the valve handle is accidentally opened during
CHARGING, close valve and press the plunger handle down to return the colorant to the canister.
If the colorant level is low in the canister, air can also be sucked into the cylinder.
Press the plunger handle down to return the colorant to the canister. Add 1 or 2 quarts of new
colorant. The cylinder must be re-primed. Refer to the instructions on chapter 4.

5.4 Smart Gauge
The Smart Gauge (Figure 5-5) is an innovative way of dispensing increments smaller than 1 part.
The Smart Gauge allows you to dispense in 1/8 part increments.
For formulas specifying dispenses for example a 1/2 part, rotate the Smart Gauge knob until the
1/2 number is aligned with the pointer.
The Smart Gauge settings can be used in combination with a regular setting, thereby making
complete dispenses possible with a single discharge.
IMPORTANT: ALWAYS return the Smart Gauge knob to the “0” position after completing a
dispense.

6MAINTENANCE
6.1 Daily Maintenance
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.
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.
