E. Blower Belts
1. To gain access to each blower belt compartment remove
the four screws shown in Figure 4-8. Then, lift the rear
shroud off its hangers.
If access to the blower motors is required, remove the
three mounting screws (two on the front of each shroud
and one on the rear). Then, lift the end shroud straight up
and off its hangers.
2. Check each blower belt for cracking or excessive wear.
3. Check for amount of belt deflection in the center of the belt,
1/2″ deflection is acceptable, see Figure 4-9.
4. If necessary, replace belt.

electrode assembly.
