Section 8.0 MECHANICAL MAINTENANCE WARNING: DISCONNECT THE MAIN AIR SUPPLY BEFORE SERVICING THE

MACHINE!! 8.1 Wood chips and other foreign material should be blown off of the escapement

assembly, feed track, and anvil assembly at least once per day. A build-up of foreign material may result in the machine jamming. The vibratory bowl should be cleaned with a quality degreaser (ex. 409 Spray) at least once per day. Do not use lubricating products such as WD-40.

8.2 Test the safety switch at least once a day. Place a work piece in position but do

not press downward to engage safety. Press the foot pedal. If the machine fires, have the safety repaired immediately. Do not operate the machine if the safety is not functioning properly.

8.3 Disassemble and clean the anvil locator/rivet tool at least once per month. Heavy

users or those with a high foreign material build-up should disassemble and clean the anvil more often.

8.4 The entire machine should be examined every week. All bolts should be tightened.

Missing bolts, retainer rings, spacers, and other hardware should be replaced and all assemblies should be cleaned and examined.

8.5 The main air cylinder is permanently lubricated and does NOT require an oiler or

lubrication. The use of an oiler could result in a machine malfunction. The pneumatic components do not require an oil lubricant either.

8.6 The pneumatic components do require some care. Keep them clean and free from

oil and/or dirt. Pneumatic components operate best with clean, dry air. If moisture is evident in your air, a dryer must be installed. Air filter may require draining from moisture being removed from the air. Drain the filter as needed. Failure to comply with these criteria could result in rejection of warranty claims.

8.7 If the drive cylinder becomes damaged or requires repair contact your nearest

Stafast location. Opening the cylinder will void its warranty.

Section 9.0 TUNING VIBRATORY BASE UNITS 9.1 Conduct a visual inspection:

1. Examine the bowl for cracks and loose tooling. 2. Examine the vibratory base leaf springs and spacers for any cracks, rusting, or

loosening.

3. Examine the rubber feet to make sure they are still soft and attached tightly. a. Replace any hard or cracked rubber feet. b. Apply Loctite 242 (medium strength, part no. 24231) to threads and

tighten bolts.

4. Examine the wiring. a. Repair or replace if necessary.

9.2 Adjust the coil when the bowl is in place and the base is running:

1. Raise the coil as high as possible without rubbing on the armature. a. Use an open end wrench to adjust the nuts on the coil to adjust height. b. Listen to the bowl run. You should not hear the coil rubbing against the

armature.

2. If needed, lower the height of the coil. a. You should get as much vibration as possible without the coil touching the

armature. 9.3 Adjust the M12 bolts in the center of the bowl when running:

1. Loosen and then tighten the bolt until vibration is as high as possible.

9.4 Tune the springs when the base is running. Adjust the upper and lower bolts on each set of leaf springs as follows:

1. First, tighten all the lower bolts on all 4 sets of springs so they are very tight. 2. Next, focus on one set of springs at a time.

a. Start with the upper bolt on one set of springs and loosen it. Now, slowly tighten until vibration is as high as possible.

b. Repeat this on the next 3 sets of springs.

9.5 Steps 9.3 & 9.4 may need to be repeated until the desired vibration is achieved.
