4. Installation and Preparations before Operation
4.1 Installation
Please refer to Installation Guide.
4.2 Preparation before operation
A The colorant in each can must be fully mixed (It is not recommended to be mixed by shaker as too
many bubbles may appear that would cause the chromatic aberration).
B Remove each canister lid and pour the colorant into the corresponding canister.
C Before operation, remove the air out of each pump. Follow the procedures:
a Press down the black button and lift the black gauge. Align the maximum value of the gauge
with the upper surface of the handle, and then release the black button. Lift the handle to its
highest position and press down it slowly. Do not touch the valve key during this process. Repeat
the foregoing operation for 5-6 times.
Press down the red button and lift the red gauge. Align the maximum value of the gauge with the
upper surface of the handle, and then release the red button. Lift the handle to its highest position
and press down it slowly. Do not touch the valve key during this process. Repeat the foregoing

5.3 Dispensing Procedures
The minimum shot of the dispenser is measured by the minimum mark of the red gauge. The measured
value is on the label on the bottom of the gauge. 2957/384 means 1/384 U.S. ounce. It is similar for the
black gauge. If the label on the bottom is 2957/48, and the number on the black gauge is “30”, that means
30X29.57/48ml. If the number on the red gauge is “2”, that means 2X29.57/48ml.
Dispensing Procedures:
A．Check the formula and confirm the volumes for colorants.
B．Open the base paint can and put it onto the proper platform. Press the locking handle to the
horizontal hole and rotate the turntable to make the desired nozzle right above the base paint can. Pull the
locking handle to the vertical groove and trim the turntable to reset the locking handle.
Notice: the base paint can shall be as near as possible to the housing.
C．See figure 6, press the black (red) button and lift the black (red) gauge. Align the measuring mark
with the upper surface of the handle then release the button to lock the gauge.

D．Lift the handle and make it contact with the gauge head. Hold on for several seconds to make sure
the cylinder is full of colorant.
Notice: do not open or operate the valve key when lift the handle. Or the air would be sniffed into the
cylinder and cause inaccuracy.
E．Shown as Figure 7: rotate the valve key for 90°and press the handle slowly to its bottom. Release
the valve key and make it back to the original position.
F. Press down the black button, reset the black gauge to its zero position. Release the red button.

(Repeat the foregoing step if one colorant is required for several times)
Notice: the gauge is precision tool, do not drop the red/black gauge when reset it back to its zero
position to keep its accuracy.
Notice: reset the gauge to the zero position when not using it.
The red gauge volume plus the black gauge volume shall equate to the formula volume of the
colorant.
G．Repeat the foregoing steps for the next colorant.
6. Maintenance
6.1 Daily Maintenance
A. Move each plunger handle up and down three times every day to ensure smooth flow of the
colorant and to avoid blockages in pumps and canisters.
B. Clean the nozzle with soft cloth or cotton moistened with water or thinner to keep it
unobstructed.
C. Move the valve handle 5 times every day. This can keep the valve in optimum working condition
and prevent the colorant from drying in the valve.
D. Check the colorant level in canisters and refill if necessary. If the colorant is lower than the
feeding level, air will enter the pump when lifting up the plunger handle. This will cause
inaccuracy in dispensing.
6.2 Weekly Maintenance
A. Check if the canister is loose. If so, tighten the fixing screws under the turntable (see
Replacement of Canister)
B. Check if the gauge’s scales are damaged or covered with colorant. Clean or replace the gauges if
necessary.
6.3 Periodical Maintenance
The dispenser must be maintained every 3-6 months for the following aspects:
A Check the fixed base is loosed or not (Figure a)，If loosed, push the base to the most bottom
position, fasten two screws of the base Symmetrically with inner hexagon Spanner. (Figure b，

Santint
M3 Manual Dispenser V1.0 8
c)，do not screw too hard.
B Open canister lid during the process of mixing to observe if the agitator works normally. For any
abnormity, stop mixing and repair the canister.
C Clean the nozzle: Rotate the valve handle and pull out the nozzle, Clean the nozzle with cotton
moistened with water or thinner. Then rotate the valve handle once again to reinstall the nozzle.
Notice:
1. After reinstallation of nozzle, dispense out small amount of colorant to fill the nozzle. The
reinstallation must be carried out gently.
2. The manufacturer provides with large-size nozzle; the end user can choose the correct-size nozzle
according to the colorant’s viscosity.
6.4 Yearly Maintenance
After long period of service, the inner wall of the pump or the canister may stick some colorant. This will
make the piston move hardly and cause measurement errors. Small amount of colorant is allowed. But if
too much may cause great difficulties in the movement of the piston and generate measurement errors. In
this case, cleaning must be done to canisters and cylinders.
To clean without dismantling the canisters assembly:
a Remove the canister assembly from the turntable;
b Pour the colorant in the canister into a clean container;
c Clean the canister with warm water to get rid of most of the adhesive colorant;
d Properly dispose the mix of cleaner and colorant according to local environmental regulations;
e Reinstall the canister on the turntable;

j Repeat step g-i until the canister is clean (the cleaner can be used for 1-3 times. Yet fresh cleaner is
required for the final cleaning);
k Leave the canister to dry out before re-filling new colorant.
6.5 Replacement
A Replace Sniff-Back Piston
Remove the nozzle (see above-mentioned method), rotate the valve handle to its maximum travel.
Pull out the broken sniff-back piston. Install a new sniff-back piston with small O-ring. Reinstall the
nozzle and release the valve handle.

6.6 Calibration
Normally the machine has been precisely calibrated and ready for use before leaving the factory. Yet
in the following cases, new calibration is necessary:
When replacing either the Rough or Fine gauge or the location pin of the said gauge.
The dispensing result is not accurate.

Santint
M3 Manual Dispenser V1.0 11
A. Check the condition of the gauges or their location pins. Replace them if necessary.
B. Press and hold the black button until the black gauge reaches zero-scale. Release the black button
back to the original position. Use an inner hexagon spanner to adjust the screws on the active base
until its top surface touches the bottom surface of the gauge knob.
C. Press and hold the red button until the red gauge reaches zero-scale. Release the red button back to
the original position. Use an inner hexagon spanner to adjust the screw on the plunger handle until
its top surface touches the bottom surface of the red gauge knob.
D. Measurement: Measure the minimum dispensing quantity of the black gauge and red gauge
respectively according to Dispensing Procedures (B-E).
E. Compare the measured value with the standard one to find their difference. For any difference
exceeding the permitted range, you’ll have to adjust the screw(s) on the active base or the plunger
handle.
F. Repeat the step D and E until you get the required minimum dispensing quantity.
6.7 Long Time Not Using
If long time not using, and there is colorant in canister, the machine must be kept to connect the power
supply. Dispense out some colorant (1ml) periodically (every 5 days) to avoid the nozzle becoming dry
and hard. Otherwise, disconnect the power supply, pour the colorant into clean(or corresponding) canister,
and clean the container to avoid the colorant becoming dry in the pump.
