3 Maintenance
WARNING
To avoid being burned, electrocuted, or
otherwise injured, always unplug the
machine and allow it to cool down before
making adjustments, clearing obstructions,
lubricating, cleaning, or disassembling.
Taking Care of the Plunger,
Hopper, and Cylinder
The plunger, hopper, and cylinder of your Donut
Robot are precision instruments. If you take
good care of them, they will perform well for
years. Follow these guidelines:
• Clean these parts only in the manner
explained in this manual.
• Handle these parts with care. Avoid
dropping them on hard surfaces.
• Do not force the machine if it becomes
jammed. To avoid damaging the
plunger, disassemble the machine and
remove any obstructions.
Lubricating
Daily
Before using the machine each day, apply edible-
grade mineral oil to the plunger connecting rod.
The oil should penetrate the ball lock and the
spring socket. See Figure 3-1.
Figure 3-1. Lubricating the Connecting Rod.
Weekly

swing column where it contacts the swing
column bracket.
