6.0 MAINTENANCE8530 Shatterbox6.1 Shatterbox Part NumbersFollowing these written instructions are a parts list and diagrams (pages 22-24) of theShatterbox mechanism and cabinet. Note that all SPEX parts have 5-digit inventory numbersthat must be used to order them. However, most of these parts also have 1-digit or 2-digitnumbers that correspond to the part's position in an engineering drawing. Example: thescrews, which hold the columns in place, are part no. 26 in Diagram A, but must be ordered asSPEX Part No. 50619.6.2 Cleaning the ShatterboxDepending on how dusty the working environment is it may be necessary to clean theShatterbox regularly. The clamp and capsule retainer should be vacuumed or wiped off. Anyspilled powders or liquids should be wiped up immediately with a slightly damp cotton cloth afterevery use. This should minimize the buildup of any powders, mold/mildew, or unsightly gunk overthe life of the unit. To clean the Shatterbox mechanism, remove the access panel on the back ofthe cabinet (after unplugging the mill) and vacuum the exposed surfaces.For a properly functioning Cam-Action Clamp, it is absolutely necessary that the lever assemblyroller rotates smoothly (Diagram A, Item 13). Clean off any excess dust or dirt from the outersegments of the clamp, with special attention being placed on the hinge sections and on the roller.It may be necessary to oil the hinge and the roller from time to time. If the roller locks up, theclamp can be easily damaged.NOTE: It is important to unplug the unit from its power source before beginning any cleanupor maintenance work that is to be performed on the mill.6.3 Replacing Drive BeltsSpecial compound O-rings are used as drive belts (Diagram B, Item 34). When a drive belt fails,all four drive belts should be replaced by SPEX part no. 51793. (Neoprene O-rings will notwork.) Before installing new drive belts, check the clearance between the hubs of the couplingarm and eccentric arm (Diagram B, Items 28 and 35, respectively); the gap should be between1/16 inch and 1/8 inch (1.5 mm to 3 mm). If it is more or less than that, loosen the lock screwson the collar of the coupling arm with a 1/8-inch Allen wrench, adjust the clearance by movingthe coupling arm up or down on the motor shaft, then tighten the lock screws.Visually inspect the coupling arm and eccentric arm to make sure they are parallel, and notbent; if they are damaged, they should be replaced.Install the new drive belts in a diamond pattern, two up and two down as in Diagram B. Spinthe funnel (Diagram A, item 23) by hand to make sure the two arms spin together freely, andthe drive belts are parallel.Page 17 of 28 SPEX SamplePrep LLC January 2010
