Please read and follow all recommendations and instructions stated herein for CMX+
Clean the Clean Machine:
Contaminates from the machining and assembly processes may remain in the tank of your CMX-O. To clean, fill the tank as stated per Sect B. Use an aggressive solvent. Insure that both fill cap & control valve are tightened securely. Shake well to agitate to clean. Empty contents in suitable container by draining & removing control valve completely.
(A) SKID PAD ADJUSTMENT, CLEANING PAD INSTALLATIONS:
1) The skid pad is designed to snap on/off via skid pad spring clips.
2) The cleaning pad is installed by rotating spring clip appropriately and wrapping cleaning pad, velvet side down, around skid pad, so that cleaning pad is centered and the pad ends do not protrude into large hole on skid pad.
3) CMX may be used as abrasive type cleaner by installing abrasive type pads. Sheet rock sanding mesh (Fine) is good or 600+ Emory paper.
(B) SOLVENT HANDLING AND FILLING:
Solvents are most easily and safely dispensed by using a 5 -10 ccm syringe which is available at pharmacies for dispensing children’s liquid medicines, and cost about $1.50. Handling and filling should be performed on suitable surface in suitable area.
1) Close control valve, turn screw knob clockwise until valve seats.
2) Remove fill port cover. Screw.
3) Use syringe and draw 3CC solvent. Transfer solvent slowly to CMX through fill port. Follow the specific directions for the correct amount in your cars instructions.
4) Keep fill port cap on during use, but do not tighten completely or vent will be closed preventing proper drip rate.
5) Crack open control valve, observe drip rate by holding CMX above surface and viewing nozzle.
6) Adjust drip rate to about 10-15 drops per minute or less. CW reduces drip rate, CCW increases.
7.1) No drip or drip not adjustable. Check fill port…………….Plug should be loose. Nozzle blocked…………..Use wire or needle to clear. Solvent level too low……Min. 3CC needed. Add more solvent.
7.2) When drip is adjusted as described above CMX will not harm plastic ties or painted areas even when standing still. Cleaning pad allows solvents to evaporate. It is a good practice to tighten fill plug and close valve completely when CMX-O is not in use. Warning: Proceed at your own risk. Failure to read, understand, and follow all instructions stated herein and furthermore stated on labels, and by the manufacturers of solvents, will result in damage and harm to you, the environment, or your equipment.
1) CMX comes to you ready to run.
2) CMX may be pushed or pulled by any locomotive with sufficient traction. Short, 8 wheel drive, four axle diesels are ideal. For highly contaminated track place CMX-O before power unit. (2 locos may be needed)
3) Cleaning pad should be sufficiently wetted with solvent to clean properly. This can be usually seen as wetness on pad or cool feeling of skid pad. This is about 10 drops a minute. Cleaning pad should be centered on skid pad fore to aft and right to left.
4) Cleaning pad may be cleaned while in use by using a solvent wetted rag and rubbing cleaning pad until dirt is removed. Pads may also be washed in detergent and be re-used.
(D) MISCELLANEOUS NOTES:
1) CMX meets NMRA gauge dimensions (HO Models).
2) CMX is designed so nozzle receives solvent about 1/8″ above bottom of tank. This leaves sediments at bottom of tank and protects nozzle from clogging. This is about 3CC volume and gives false impression of being usable solvent.
3) CMX has limited spill fill port design. The fill port protrudes about 1/8″ into tank creating inside lip to impede spills. Held inverted about 1-2 CC of solvent will still remain in CMX.
4) Truck mounting screws should not be overtightened or thread damage to screws or bolster may result.
5) Standard Athearn delrin trucks have been supplied to minimize short circuits. The mounting is good for many other truck types if you choose.
6) CAUTION: When removing plug, or valve stem from CMX, be sure “O” rings and packing washers remain in place.
7) Initially, your layout may require several passes with CMX to clean properly. Once clean, you will only need to use CMX once or twice a year.
(E) Solvent Options:
The following solvents may be used with CMX:
Most aggressive group: (Observe precautions stated on container and herein)
Nail Polish Remover, Laquer Thinner, Acetone, MEK, Toluene & Zylene.
This group of solvents are the most effective but the most dangerous. You will probably need to use these to start and then once a year there after. Plastic from wheels and other organic matter is the most significant contaminant on your track. Since you need to follow the same precautions for all the solvents in this group, use Nail Polish Remover or Acetone, which are readily available.
Moderately aggressive group: (observe precautions stated on container and herein)
Isopropyl Alcohols, Paint thinner & Water based solvents(Fantastic or 409). This group of solvents will not remove plastic but are satisfactory for routine maintenance.
While any of the above solvents can be used if precautions stated on the container and herein are followed, Tony’s Recommends using Acetone or Isopropyl Alcohol, as these two solvents have proven the most effective.
PLEASE NOTE! DO NOT LEAVE THE CMX CLEAN MACHINE SITTING ON THE RAILS AFTER CLEANING, AS THE RESIDUAL SOLVENTS IN THE PAD CAN SOFTEN OR MELT PLASTIC TIES.
