My Cassese CS89 Underpinner has recently developed a problem. The wedge is intermittently not entering the moulding completely. I use the black plunger for hardwood and the white for softwood. I adjusted the limit stop, as instructed by a technician, and it temporarily solved the problem. Then it started again. A technician from Larson-Juhl , told me to place the phone next to the machine to see if he could determine if it was leaking air, and he determined that it was not. I bought the machine used, and I found a different wedge driver. Assuming that it was new, I replaced the old one with it. This also did not solve the problem. I decided to purchase a new driver with the assumption that the driver provided was not new. If replacing the driver with a new one, I can't imagine what else would be wrong. Does anyone have any insights to this problem? As I said, sometimes the wedge enters completely, and sometimes it does not. If the new driver does not solve the problem, I can't imagine what could be wrong?
 
Could be an issue with the pneumatic controller box. Have you run some pneumatic oil through the machine to be sure it is lubed. Seals will harden if the machine has been sitting.
 
Or you will want to lube the shaft that the nail travels through. don't those machines typically come with a special type of lube?
 
Yes he got the white grease and it needs to be applied but it needs internal lubrication as well.
 
Mine has a hex screw that holds the hammer in place. It needs to be tightened periodically, or it will not drive the nail in completely.

Call Active Sales 800-937-2255.
 
Had a similar problem a few months back ...

There is a "limit switch" that gets pushed from underneath when the plunger is activated.

It's on the bottom of the block where the air enters the machine ... that block is attached to the body with a hex bolt.

My hex bolt was loose, causing the limit switch to intermittenly be triggered early, or late. Make sure that is tight and that the contact is properly lined up with the limit switch.

hope that was clear?
