7.0Maintenance

7.1Belt replacement

1.Disconnect the power to the machine to prevent accidental start-ups. If the machine is plugged into an outlet, unplug it. If the machine is hardwired to a branch circuit with a junction box, remove the fuse or trip the circuit breaker to the branch.

2.Remove the lock knob and top cover (See Figure 6).

Figure 6: Top cover components

3.Remove the side guard and table.

4.Release the belt tension by turning the tension handle in a counterclockwise direction (See Figure 7). If the handle is difficult to turn, perform Track mechanism maintenance according to the instructions in section 7.2.

Figure 7: Belt adjustment components (Note top cover removed for removal and replacement of belt.)

5.Remove the belt.

6.Check the drums and platen for scoring or signs of wear which might require service or replacement.

7.Check the height of the platen with a straight edge. If it is not 1/32 inch above the drums, adjust it according to the instructions in Platen Replacement or Adjustment in the Machine Setup section of this manual.

8.Check the drums for looseness which might cause tracking problems. Correct any loose condition by tightening or replacing any parts as required.

9.Slip the new belt onto the drums and platen.

10.Adjust the tension handle clockwise until the belt is flat against the platen and there is no curling or buckling of the belt in the middle.

11.Turn the drums by hand to see if the belt tracks more-or-less true. JUST BECAUSE THE OLD BELT TRACKED CORRECTLY DOES NOT MEAN THE NEW BELT WILL. Always check the tracking when replacing a belt.

12.To adjust the tracking:

12.1.Plug the machine back into the outlet or reestablish power in the branch.

12.2.Loosen the tracking lock knob.

12.3.Jog the motor on and off as necessary to observe the tracking, and turn the tracking knob as necessary to make the belt track in the center of the platen and drums. Turn the tracking knob clockwise to move the belt toward the right and counterclockwise to move the belt toward the left.

12.4.When the belt seems to be tracking correctly, turn the motor on and leave it running while fine tuning the tracking.

12.5.Lock the tracking lock knob.

12.6.When the lock knob is secure, turn the power off and disconnect the machine from the outlet or branch as in Step 1, above.

13.Replace the table, side guard, top cover and lock knob by reversing steps 3 and 2, above.

14.If you have not already done so, reconnect the power to the machine and return it to service.

7.2Track mechanism maintenance

While the use of a dust collection system can extend service intervals, an accumulation of dust will almost certainly require periodic cleaning of the tracking mechanism. The more continuous the use of the machine, the more frequently this maintenance should be performed.

As mentioned in the preceding section, the need for required maintenance is often indicated by difficulty in adjusting the tension/tracking mechanism.

1.With the belt removed according to the instructions in section 7.1 Belt replacement, pull out the upper tracking system and clean away all
