This article and video shows a general maintenance routing on a CM2400. This unit has not been cleaned in THREE years (NOT recommended *smiley*). This machine has been abused and yet, its durability has withstood many hours of commercial work. The following are the main items to inspect, clean and maintain. Please note: While the airlock seals were changed on this machine, it is not a part of this video.
Our machines contain very few proprietary parts. As such, we use a common high capacity filter (16”x 20” x 1”) which you can purchase directly from us or your local hardware store.
After 600-800 hours of dense packing, you may need to change your airlock seals. Even after three years, (of attic blowing), this particular machine still had a little life in the seal. See this article and video on changing airlock seals on the CM2400
Vacuum and Use an Air Pressure Blowout Hose
When the air filter is removed, you will have direct access to the blowers. Vacuum out the dust that has accumulated. Vacuum out and blow out the dust from your chains, gears and all around the machine. You will see that material can build up on the backside of the machine.
Grease the Four Bearings
You can imagine, after three years of neglect, that the bearings would be pretty dry. In the case of this machine, two of the four were “bone dry.” They did not have any detectable wear and just needed an extra dose of grease. What kind of grease do we recommend? Synthetic Multi-Purpose Grease NLGI #2 (GLC).
Inspect and Lubricate Chain
- Check the chain tension and keep it very taught.
- Lubricate every 3 months w/ ‘non-sticky’ lubricant. Note: a regular oil will cause excess fiber to stick and build-up on chains. Some of our customers use a motorcycle chain lube. Cool Machines uses Moly Chain lubricant, Grainger part# 5PE62.
Blower Box Hose
Inspect the hose between blower box and airlock. Make sure it is has no gashes and that the hose clamps are tight and in good condition.
