HS7N

Overview

The Hobart HS7N is an automatic heavy-duty slicer in the HS Series. It has a non-removable knife and is suited to commercial preparation of meat and cheese. The HS7/HS7N series uses a 1/2 HP knife-drive motor and a 13-inch CleanCut knife with a cobalt-alloy edge. Hobart states that the CleanCut knife is intended to stay sharp longer and improve slice quality and yield.

The HS7N combines automatic product carriage movement with an adjustable gauge plate, allowing operators to prepare thin slices through thicker cuts. The carriage has four speeds and three stroke lengths. The machine also incorporates safety interlocks and features for access during cleaning. Hobart lists operator resources for the HS7/HS7N, including manuals, videos and troubleshooting resources.

Key Features

• Automatic carriage: Variable-speed carriage provides four speeds and three stroke lengths to accommodate different products and slicing tasks.
• 13-inch CleanCut knife: The knife is made from 304L stainless steel with a high-performance Stellite alloy edge. The HS7N model has a non-removable knife.
• Double-action indexing: The first full turn of the indexing knob provides control for shaving, chipping and thin slicing. A second turn opens the gauge plate for thicker slicing, which holds its position for consistent cuts.
• Adjustable slice thickness: The gauge plate adjusts for slices up to 1 inch thick. Machined grooves on the gauge plate and knife cover reduce drag and support smooth product movement.
• Automatic drive: A Hobart Poly V-Belt drives the knife at 430 RPM. The automatic carriage has four speeds and three stroke lengths.
• Top-mounted Borazon sharpening system: The system uses two Borazon stones and is removable for cleaning. Hobart states the stones have a lifetime guarantee.
• Safety interlocks: Zero knife exposure helps protect the operator. The no-volt release requires the slicer to be restarted after a power failure or unplugging, and the home-to-start interlock prevents starting until the carriage is in its home position.
• Cleaning access: The lift assist helps users reach beneath the slicer. The carriage tilts and is removable, and the ring guard cover is removable to help access the area around the knife.
• Sanitary construction: The one-piece burnished-aluminum base has fewer crevices where food debris can collect. The product tray and gauge plate are also burnished aluminum, and the top cover is stainless steel.
• Available accessories: Hobart lists a full fence, food chute and debris deflector as accessories available at extra cost.

Installation & Requirements

The HS Series installation guide says to check the machine data plate before installation and verify that the electrical service matches its specifications. The data plate is on the left side of the slicer base. The HS7/HS7N specification sheet lists the standard electrical configuration as 120 V, 60 Hz, single phase and 5.6 amps.

The slicer’s cord has a three-pronged grounding plug. The installation guide says it must be connected to a properly grounded receptacle and warns not to remove the grounding prong. If the receptacle is not the proper grounding type, the guide directs users to contact an electrician. The HS7/HS7N specification sheet identifies a 6-foot, three-wire power cord and a NEMA 5-15P plug configuration for the 120 V model.

The installation guide instructs users to place the slicer on a suitable counter or tabletop. To install the product tray, lower the bottom of its support arm onto the carriage hinge pins, tilt the tray toward the gauge plate, and tighten the support-arm knob. No clearance or ventilation requirement is stated in the supplied sources.

Operation

The HS7N is an automatic slicer: its product carriage moves automatically while the knife slices the product. Operators can select among four carriage speeds and three stroke lengths. The double-action indexing knob allows precise adjustment for thin slicing and opens the gauge plate further for thicker cuts. The gauge plate can be set for slice thicknesses up to 1 inch.

The machine is intended to start only when the carriage is in its home position. Its no-volt release requires a restart if power fails or the slicer is unplugged. Hobart’s series sheet also identifies a moisture-protected push-button switch. The sources provided here do not include a complete operating sequence, so operators should consult the HS7/HS7N operator manual for model-specific procedures.

Cleaning & Maintenance

The supplied HS Series installation guide says to unplug the machine and turn the index knob fully clockwise to close the gauge plate before cleaning. It warns users to exercise extreme caution near the knife. The slicer must be thoroughly cleaned and sanitized before first use, and the guide says removable parts should be taken off, cleaned and sanitized according to the instruction manual for the specific model.

After removing the parts, the guide instructs users to wipe the slicer surfaces with a cloth soaked in mild detergent and warm water, rinse with a fresh cloth and clean water, and apply sanitizing solution. It says to use only products formulated to be safe on stainless steel or aluminum. Allow removable parts to dry fully before reassembling the slicer, and follow the model’s instruction manual for removal and reinstallation procedures.

The HS7/HS7N series sheet identifies several features that support cleaning: a lift assist for access beneath the slicer, a tilting and removable carriage, a removable ring guard cover and a removable top-mounted sharpener. Hobart states that the ring guard cover can be removed to reveal a space between the knife and guard for easier flossing. The Borazon sharpener is warewasher safe, and the removable meat grip assembly is dishwasher safe. The sources do not provide a maintenance interval.

Applications

The HS7N is suited to commercial kitchens and food-preparation operations that need automatic slicing of meat or cheese. Its capacity accommodates products up to 5.75 x 10.75 inches rectangular or 7.5 inches in diameter, and its gauge plate allows slice thicknesses up to 1 inch. The variable carriage speeds and stroke lengths support a range of product sizes and slicing tasks.
