MAINTENANCE
PUMP TUBE MAINTENANCE
Pump tubing is a wear item. Contact Hobart
Service to replace tubing periodically on grease
pump, chemical pump and water pump to
avoid leakage.
As pump tubing wears, leaks can occur. In
the event of tubing leak or break, machine is
designed to direct liquids to outside of oven
(Fig. 52). If this condition is observed, contact
Hobart service.
YEARLY CLEANING
Wash nozzles are located between the ceiling of the oven and the upper cover
to clean the convection fan and heating chamber. However, it is recommended that
you inspect and clean the oven once yearly, as needed.
Clean the ceiling of the oven interior to remove potential grease build-up.
Excessive grease build-up on convection fan blade(s) and / or upper cover will
decrease the oven's cooking performance over time.
NOTE: For ease of cleaning, replacement fan blade(s) are available from Hobart
Service.
1. Open the door. Make sure that the drive arm is in the downward position
(Fig. 53). Press OFF.
Disconnect electrical power supply to the machine and follow
lockout / tagout procedures before cleaning or servicing.
Hot glass, grease and parts can cause burns. Use care when
operating and servicing the oven.
2. Remove the rotor. Lift up on the side of the rotor opposite the drive arm. Then, lift up and out to
disengage the rotor from the two drive pins on the drive arm (Fig. 54).
