Procedures
Ball Screw Slides
The slides should be greased with the fitting on the carriage every 100KM or approximately
once a month. Clean buildup on the ball screw and seals. Use lithium-type, soap base, grease
(JIS Type 2). Not all models have slides with grease fittings. If a slide does not have a grease
fitting, apply a small amount of grease to the slide, and move the slide back and forth.
Inspection
The cables in the flexible cable carrier should be examined for wear. Replace all worn cables.
Examine the top frame and end effecter for loose screws.
Conveyor Belt Replacement
1. Disconnect and lockout the power and air supplies.
2. Remove the dust cover plate. The dust cover plate is near the conveyor motor on the
inside of the conveyor.
3. Remove the conveyor belt from the pulley wheels.
4. Clean the conveyor rails where the belt rides.
5. Install a new conveyor belt. Put the belt on the pulley wheels farthest from the motor
first.
Note: Make sure that there are no twists in the belt.
6. Put the belt around the large pulley wheel, then around the other wheels.
7. Rotate the pulley wheels several turns by hand to make sure the belt is correctly
installed.
8. Put the cover plate on again.
Devices and Valves
Refer to the individual component and valve manuals for information about the
dispensing/spraying equipment and any other installed devices.

Servicing the Inline Material Filter
Machines that dispense low viscosity materials may have an inline stainless-steel filter on
the pressure vessel. If material flow is reduced, the filter element could be clogged. All parts
of the filter are stainless steel and can be cleaned several times before replacing. To clean
or replace the filter:
1. Turn air supply pressure to the pressure vessel “Off”.
2. Turn the material valve on the vessel “Off”.
3. Use two large adjustable wrenches to separate the two sections of the filter.
4. Remove the stainless steel filter element, record the correct orientation.
5. Clean or replace the filter as necessary.
6. Assemble the filter and pressurize the system. It may be necessary to purge air from
the system.
7. Turn air supply pressure to the pressure vessel “On”.
8. Turn the material valve on the vessel “On”.
Exhaust Fan Setup
1. Turn the power “OFF”.
2. Open the electrical enclosure.
3. Use the dial in the overload relay in the electrical cabinet to set the overload relay
current to 1.0 * FLA for the motor. The FLA is shown on the motor nameplate.
4. Set the reset button to Manual.
5. Restart the machine.

Pressure Differential Switch Setup
Note: The flow velocities referred to are only valid for a 5” duct diameter.
1. Turn on the exhaust at 100% speed.
2. Examine the operation of the pressure switch input. The input should be “ON” with
the exhaust at 100% speed.
3. Turn off the exhaust. Make sure the pressure switch input turns “OFF”.
4. Decrease the outlet of the exhaust until the airflow velocity is between 2200-2350
ft/min (300-320 CFM) at the exhaust flange screen.
5. Make sure that the exhaust pressure switch input is still “ON”. If it is not, turn the
adjustment screw counterclockwise until the input turns “ON”.
6. Turn off the exhaust. Make sure the pressure switch turns “OFF”.
7. Turn on the exhaust. Make sure the pressure switch input turns “ON”. If not, turn the
adjustment screw counterclockwise again until the input turns “ON”. Make sure that
the input turns “OFF” when the exhaust is turned off.
8. Decrease the outlet of the exhaust until the airflow velocity is between 1840-2000
ft/min (250-275 CFM) at the exhaust flange screen.
9. Make sure that the pressure switch input stays “OFF” at this airflow velocity. If the
input stays “ON”, turn the adjustment screw clockwise SLOWLY until the input turns
“OFF”.
10. If an adjustment is made, make sure the input at the airflow velocity used in step 4
still operates. The input should still turn “ON” at an airflow velocity within the range
used in step 4.
11. Set the exhaust to off and back on again. Make sure that the pressure switch input
stays “OFF” for an airflow velocity within the range used in step 8.
