Safe Work Practices

Beware of High Voltage

This equipment uses high voltage. Serious injury can occur if you
or any untrained or unauthorized person installs, services, or
repairs this equipment. Always Use an Authorized Service agent to
Service Your Equipment

Noncombustible Floors Only

Make sure your floor is noncombustible. Do not operate your fryer
on floors that are wood, carpeted or have rubber mats.

• Placing your fryer on a combustible floor could cause a
fire. Serious injury could result.

• Examples of noncombustible floors where you can safely
place your fryer are concrete, tile, and ceramic.

Keep The Area Around Your Fryer Uncluttered

Make sure to keep the area around your fryer clear of any
obstacles.

Serious injury can occur if you trip or fall near the fryer. You could
be burned by hot shortening that splashes out of the fryer or by
falling against the hot metal of the fryer.

Keep The Floor Around Your Fryer Clean Of Shortening

Doughnut Fryer Introduction

Keep The Lid Closed When The Fryer Is Not In Use

Hot shortening can splash if someone moves the fryer or bumps
into it. Serious injury can occur if hot shortening splashes out of
the fryer.

Do not lean, sit or stand on the fryer or perform any maintenance
or cleaning duties while the fryer or the shortening is hot. You
could be burned.

Keep The Casters Locked

To avoid spilling shortening, keep the casters locked. If any
shortening spills near your fryer, clean it up immediately.

Do Not Overfill The Fryer With Shortening

Hot shortening and steam may escape and burn you if you put too
much shortening in the fryer. Fill the fryer to approximately one
inch below the fill marks that are inside the fryer vat. Heat the
shortening. If needed, carefully add more shortening to bring the
level to the fill marks.

Do Not Let Any Water Get Into The Fryer

Always remove excess moisture from food before placing it into
the fryer vat. Water will cause the hot shortening to spatter. You
could be burned.

Wear Safe Clothing Appropriate To Your Job

Always wear your insulated mitts when handling the racks or touch
any hot metal surfaces. You received a pair of insulated mitts with
your fryer. If you lose or damage your mitts, you can buy new ones
at your local restaurant equipment supply store or from your local
BKI Distributor.

Always wear non-skid shoes when working around the fryer or any
other equipment that uses shortening. Never wear loose clothing
such as neckties or scarves while operating your fryer. Keep loose
hair tied back or in a hair net while operating your fryer.

Always wear appropriate personal protection equipment during the
filtering process to guard against possible injury from hot oil.
