Calibrate
the pump by turning the black adjusting knob on the pump to the right until
the movement stops. The turn the knob left to the desired setting. Pre-set
at "34 clicks' from the factory. Two types of pumps are available: shutoff
and non-shutoff. Non-shutoff pumps are furnished as standard equipment on
all Merlicator's. This type of pump allows Merlube liquid to continually flow
even when turned to the stop position or damage to the pump will occur.
Minimal flow is achieved when the pump is turned counterclockwise until it
stops. Shut-off models are available on a special order basis. Consult with
factory. Again, the pump adjusts like a volume control. Turning the knob to
the right increases the volume of liquid. Turning the knob to the left
decreases the volume of liquid. **Danger: Do not run the pump dry. Damage
may occur. Leave liquid in the reservoir at all times.
2.2 Pump
(Fig 2B)
The air logic is the device that sends the
interrupted air signal to the pump. Its main function is to "tell" the pump
how often to stroke. It is adjusted by placing a small screwdriver into the
slotted adjusting screw (d) located on the fron of the logic and turning.
Turning the adjusting screw in either direction will speed up or slow down
the stroking action of the pump. Set to your desired need. (It is set at the
factory to pulsate one stroke every 2 seconds) Remember, consistency of
Merlube liquid pumped is more desirable that volume being applied. If you
took one gallon of Merlube and desired to tap a series of 1/4-20 holes it
would not be logical to pour the entire gallon on the tap at the start and
end up tapping dry holes at the completion of the job. Spreading Merlube
over the entire tapping job makes more sense - consistency over volume.
As a rule of thumb we suggest the
following: to increase the amount of liquid, increase the flow of lubricant
by increasing the number of strokes per minute of the pump (adjusting the
air logic). To decrease the flow of liquid, keep the air logic set at the
number of strokes set by the factory, but decrease the amount of liquid
flowing into the pump by turning the black adjusting knob on the pump ONE
click at a time to the left (decreasing the flow).
The system is balanced set at the factory and
pre-set to the following general purpose settings:
Pump: 34
Air Logic: One stroke every 2 seconds
2.3 Air Flow Valve
(Fig 2C)
The air valve adjusts
the flow of air which comes from the nozzles. To operate the valve, turn the
knob to the left to increase the flow of air and to the right to decrease
the flow of air. The amount of air needed is the least amount of air
possible. Just enough to get past the turbulence generated by the cutting
tool. With experimentation you will easily determine the amount that is
needed.
If you do not have enough air flowing
from the nozzle you cannot get the liquid to the tool. If you know the pump
is pumping liquid out the tube but the lubricant doesn't seem effective you
should increase the flow of delivery air.
2.4 On/Off Slide Switch
If your Merlicator is
furnished with a on/off slide switch the unit is activated by sliding the
black knob to the right. This allows air to pass through the manifold and
activate the pump, air logic, and air flow valve. Conversely, sliding the
black knob tot eh left stops the air from passing through the system.
2.5 Solenoid
If you Merlicator is
activated with a factory installed electric solenoid, it must be wired from
inside the unit to the on/off switch of your machine. We suggest that an
electrician do the wiring. Solenoids can be furnished in a variety of
voltages (AC or DC) so it is important to match the voltage of the source to
the voltage of the solenoid. Our warranty does not cover damage from
improperly wired solenoids.
