A preventive maintenance visit should be performed every 3

months. Failure to complete PM's every 3 months is considered abuse of the machine, and therefore voids the war-

ranty. Proof of PM must be documented with Grindmaster Corporation to maintain warranty coverage. To document

your PM, complete this form with signatures, place used/worn parts that were replaced during the PM inside enve-

lope, and mail to Grindmaster Corporation. Parts returned should include 2 spindle bushing evaporator seals, 2 rub-

ber bell shaped shaft seals, valve o-rings and shafts (if applicable).
