Preface

The Donut Robot Mark II-Gas is designed to
automatically cut and fry cake donut products,
and to fry yeast-raised donut products. It is not
designed to cut or fry any other products. The
Mark II Gas is available for LP Gas and Natural
Gas in the following electrical configurations:

 120 volts, 1 phase, 50/60 hertz

The Mark II-Gas is designed to be used on a flat,
stationary table or countertop, with the operator
standing opposite the control box and flue stack
of the machine. The operator must work safely
at all times and read this manual and follow its
instructions and warnings. Study the instructions
and warnings in this manual carefully. A
thorough understanding of how to install,
maintain, and safely operate the Donut Robot
Mark II-Gas will prevent production delays and
injuries.

The Mark II Gas produces only 71.5 dB(A) of
equivalent A-weighted sound pressure at
workstations. This has been determined during a
dry run of the machine, using a Bruel & Kjaer
sound level meter, type 2236.

cause serious burns or could cause someone
to slip on the floor and be seriously injured.

 To avoid electrocution or other injury,

unplug the machine before attempting any
adjustment, repair, disassembly, or cleaning.

 Hot shortening can cause serious burns.

Make sure that the system and the shortening
are cool before attempting any adjustment,
repair, disassembly, or cleaning.

 To avoid damaging the machine, never use

force to assemble, disassemble, operate,
clean, or maintain it.

 Be careful never to get shortening, water, or

other materials on the floor. If anything does
get spilled on the floor, mop it up
immediately. Materials on the floor can
cause people to slip or fall, resulting in
serious injury or loss of life.

 To prevent unintentional startup and possible

fire, unplug the machine if there is a local
power outage. When the power is restored, it
is safe to plug the machine in again.

To use the Mark II-Gas safely, heed the
following warnings and all other warnings that
appear in this manual:

 Make sure the machine is secured to the work

surface. Doing so will prevent the machine
from moving or falling, which could cause
serious injury.

 Never let water and hot shortening come in

contact with each other. Moisture causes hot
shortening to spatter, which may cause
serious burns.

 Do not overfill the kettle with shortening. If

shortening overflows the kettle, it could

 To avoid fire and personal injury, always

shut the machine down completely and wait
at least five minutes before igniting the pilot
again.

 To avoid electrocution, make sure that all

electrical cords are not frayed or cracked and
that they do not pass through any water or
shortening.

 Make sure that all electrical cords are routed

so that no one will trip over them.

 To avoid serious injury or death, always keep

the fryer area free and clear from
combustible materials.

1 Operation

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.

Lubricating

Before using the machine each day, apply edible­grade mineral oil to the plunger connecting rod.
The oil should penetrate the ball lock and the
spring socket. See Figure 3-1.

 Do not force the machine if it becomes

jammed. To avoid damaging the
plunger, disassemble the machine and
remove any obstructions.

Figure 3-1. Lubricating the Connecting Rod.

Weekly

Apply a few drops of SAE 30 machine oil to the
swing column where it contacts the swing
column bracket.
