Preventive Maintenance Program
Consumable use
If you let consumables reach complete failure, they can melt. Copper pieces can then break off and go into the coolant. In
the coolant, these pieces can cause the following problems:
 Decrease coolant flow
 Increase coolant flow errors (093)
 Cause damage to the consumables
 Cause coolant to leak at the check valve when you change the consumables
 Cause inaccurate coolant flow readings
 Decrease the life of the coolant pump
 Decrease the life of the check valve
When you do maintenance, examine the coolant filter for copper pieces. If you find copper pieces in the coolant filter,
replace both the filter and coolant. If a coolant flow error (093) occurs after you replace the filter and coolant, use the
troubleshooting procedure in your system’s instruction manual to find the correct action.
The best solution is to follow the usage guidelines for your consumables. However, if overuse occurs, you can replace the
following components more frequently.
