Air Cylinder Seal Leaks: If the web guiding system starts to respond slowly or goes to one direction and does not return, there is a chance that the piston seal is worn and needs to be replaced. This can cause "Blow-By"; meaning the air is blowing past the piston seal and affecting the performance of the actuator. 

Checking the Cylinder for Blow-By: Simply disconnect one of the actuator airlines from the Model 10A Servo Controller and place your thumb over the end of the hose. With the end of the hose plugged, attempt to move the guide assembly in both directions. It should move in one direction and not the other. If you are able to eventually move the guide to the other side, even at a slow pace, the piston seal is allowing air to pass and will need to be replaced. 

Basic Repair Kit

  • The basic repair kit is ideal for systems less than 10-Years old.

Complete Repair Kit

  • The complete repair kit is ideal for older systems that show a lot of wear.

System Upgrade Kit

  • The system upgrade kit is designed to bring older Coast systems up to present manufacturing standards. The ideal candidate for a system upgrade would be any system with obvious signs of oil contamination; old, damaged, or contaminated oil filtration components; plastic fittings, improper or missing components.

Changing the Sensor Side

  • Changing the sensor side is easy! Once you have the sensor on the appropriate side of the guide system, simply reverse the hoses on the actuator. Once that is done, a little more work is needed to ensure the Auto Center works correctly. Clicking the links below will direct you to a few YouTube videos to show you how it is done.


  • Hunting can be caused by having the gain too high. With the gain set too high or opened too much, the system will start to hunt.
  • This is one of the 3 interrelated settings on the servo controller and you will need a flat head screwdriver to make the gain adjustment.
  • Turning the gain down is accomplished by turning the Needle Valve to the right to reduce the flow to the edge sensor. A little adjustment goes a long way, so make minor adjustments until you have the system fine-tuned for your specific application. 
  • Please remember that whenever you make an adjustment to the needle valve or regulated air pressure, you MUST re-bias the controller (the knurled knob just above the needle valve). Turn the knob either right or left to achieve a balanced speed.
  • Hint: Move a piece of material in and out of the sensor while simultaneously turning the bias knob to verify the system moves the same speed in both directions. 

Model 10A Controller Cleaning, Inspection

  • If the Model 10A Controller is contaminated and does not perform as it should, cleaning is simple. Click here to view a video on how to clean and inspect the controller to bring it back to its like-new condition. 

Two-Stage filter element replacements

Replacing the filter elements is easy.

  • First, you will need new elements and you can find them here.
  • Once you have the elements, simply pull the tab and rotate the filter bowl to release the housing where you will now have access to the elements. The first element is the Cartridge and the second is the Coalescing.
  • Simply unscrew each and replace them with the new elements. Replace the outer housing bowl and you are done. 
  • New model filter packages have a pop-up indicator to alert when the elements have been saturated and need to be replaced. 

Applying Rubber Cork Tape to Rollers

  • When removing the old cork from a roller, it is best to machine it off by getting the insert under the tape and into the metal underneath. Once you have a good clean surface, you are ready to apply a fresh layer of cork on your roller.
  • Applying rubber cork tape to a roller is a tricky task, but with a little guidance and a couple of practice runs, you will be a pro in no time. This link will take you to a YouTube video to show you how it is done.  

Oscillating a Web into a Winder to Prevent Band Build-up

  • Utilizing a brushless gear motor, drive, and linkage, you can oscillate your web a desired distance and speed manually to prevent band build-up as you wind your material. 
  • To automate your oscillator, utilize a line speed signal to allow the drive to adjust the speed of the motor and maintain the amount of oscillation you need at all times.

Product FAQs

How much air does a Coast system require to operate?

The Two-Stage filter package requires a minimum of 60 PSI to seat the filter bowls. After the filter bowls are seated, the precision regulator will reduce the air to a normal operating range of 5 to 8 PSI.

How much air does a Coast system consume?

Under normal operating conditions, normal usage is approximately 1.5 CFM.

Air is expensive! What is the utility cost to operate a Coast system?

Since a Coast system will consume only 1.5 CFM at 6 PSI it depends on the air compressor's efficiency. For Example, at 95% efficiency and a $.08/KWH rate, usage is approximately $0.0235/hour!

Does Coast provide training and installation?

Coast technicians can provide onsite training and installation, but it's not necessary. Most systems require a few bolts to install and the training is as easy as 1-2-3; there are only three (3) settings to achieve a perfect web for your application.

Do I need to stock spare parts?

No. Coast systems are built to last, but if a part is needed, 99% of all components are on our shelves and can ship the same day.

How does a Coast system perform with Clear or Metalized film?

Perfectly! Since only a small stream of air is used to detect the material's edge, it doesn’t differentiate material detecting clear, opaque, dense, or even reflective webbing.

How well does the system work in Hot, Humid, and Dusty environments?

Flawlessly! The system takes in cool plant air and never vacuums the outside air. Therefore, the system is essentially self-cleaning.

What routine maintenance is required?

None. The two-stage filter package relies on a pop-up indicator to let you know if the filter elements have been compromised which can cause irregular movement in the system.

What are the Electrical requirements?

None. The system is powered entirely by high-pressure plant air, then regulated to a lower air pressure.

Do Coast Controls' web guiding systems have an EC Declaration of Conformity?

Yes! Coast Controls web guiding systems have an EC Declaration of Conformity with the following documents:

     Directive:     Pressure Equipment Directive      97/23/EC

                         Categorization under the Pressure Equipment Directive: SEP

                         Conformity Assessment Procedure according to Module: A
