Slicer/Applicator
MAINTENANCE AND ADJUSTMENTS
This manual contains information about how to maintain, adjust, and clean the standard Grote
Slicer/Applicator. It does not include setup, control, and operational procedures.
Manual Covers Both Hydraulic and All-Electric Slicers
Grote slicers are built with two different types of power systems, Hydraulic and All-Electric. The
All-Electric slicer differs from the Hydraulic Slicer in several ways other than just the power system
of the machine. When a function being described differs with the type of slicer each type is
identified and described in this manual.
Hydraulic Power System
A built-in hydraulic power system drives the slicing heads. Slicing is controlled by hydraulic
valves that turn the hydraulic power on and off and set the speed of the slicing heads. A typical
single head hydraulic slicer is shown in Figure 1.

Slicer/Applicator
Point
All-Electric Power System
The slicing heads are driven by an electric servo motor power system. Controls are all
electrical and controlled by a Programmed Logic Controller through an Operator Interface. A
typical single head all-electric slicer is shown in Figure 2.
Figure 2. Typical Single-Head All-Electric Slicer (To Be Provided).
Note: Both types of slicers are described in this manual. When a section applies to only one type
of system, it is identified in the section heading.
Safety Cabinetry
The cutting blade and drive mechanism for the blade are completely enclosed to provide maximum
safety for the operator. Access to the blade is easy with doors and removable covers.
Optionally provided proximity switches sense guard door closure and cut power to the slicer when
one of the doors is opened. The blade drive pulleys coast to a stop if they are running when a door
is opened.
Mechanically interlocked, defeat-proof safety switches are available as an option for guard doors.
These switches act as locks, preventing the doors from being opened until the machine has been shut
off and the blade drive pulleys have stopped rotating. The slicer must have power applied before
these switches will operate and allow the doors to be opened. A Safety Interlock Switch Locations
drawing included with the drawings at the end of the manual shows the location of the interlock
switches.
CAUTION: The safety cabinetry described above prevents an operator from gaining access to
the cutting blade from any position around the machine while the blade is running.
A conveying device under the slicer prevents the operator from access to the cutting
blade from beneath the machine. If the slicer is operated without a conveying
device in place, then steps must be taken to keep personnel from moving under the
slicer while it is operating.
Lubrication –
All Electric Slicers
Each slicing head has two grease points.
One is on the end of the rod connecting the
offset crank to the cluster box and one is on
the crank bearing. Grease all fittings after
each washdown to purge excess water from
the bearings and increase component life.
Use FML-2 Lubriplate or equivalent USDA
approved grease.

Lubrication -
Hydraulic Slicers
Grease the following bearings after each washdown of the equipment using FML-2 Lubriplate or
equivalent USDA approved grease. The remaining bearings should be greased weekly.
1. Drive side bearing block (Also grease the idle side bearing block on older machines that use
a non-sealed idle side bearing block).
2. Pivot rod ends (product holder box linkage).
3. Product holder box pivot point.
Check the condition of the bearings weekly and replace the bearings when any free movement is
detected. If movement is detected in the idle side drive pulley, replace the entire sealed bearing
assembly.
Self-contained Hydraulic Power System
NOTE: An OSHA Material Safety Data Sheet for the hydraulic oil is in Figure 4.
Some slicers are equipped with a built-in hydraulic power system. Hydraulic pump capacity is
typically six gpm with 60 hz electrical input or five gpm with 50 hz electrical input.
1. Check the reservoir oil level daily and keep it full using medium weight (SAE 10, SSU
213) hydraulic fluid. The black line indicates full and the red line indicates low. The
level should never fall below the red line.
2. Maintain the hydraulic system pressure at the normal operating pressure of 450 psig.
Never allow the machine to exceed 1000 psig.
3. Maximum operating temperature should not exceed 140 oF (60 oC).
4. Replace the return line oil filter cartridge after the first 50 hours of operation and every
300 hours thereafter. The oil filter is located inside the hydraulic tank.
Adding Hydraulic Fluid
Add medium weight fluid (SAE 10 or equivalent) if the level falls below the line in the
sight glass liquid level indicator.
1. Remove the tank cover.
2. Pour the hydraulic fluid through a 200 mesh or finer screen until the level
indicator reaches the line on the sight glass.
3. Replace the tank cover and tighten the nuts that hold it in place.

Point of Plow Wipers
Blade Scraper
A blade scraper made from three strips of Delrin that rub against the top and bottom of the
blade removes residue from the blade as it is running (See Figure 6). The top strip is hinge
mounted so that it can be moved away from the blade. The strip must be rotated down and
locked in position before starting the blade.
Check the blade scraper acetal strips daily for noticeable wear. Replace them before wear becomes
excessive and wiping efficiency suffers.
Blade Scraper -
- All-Electric Slicers
Hydraulic Slicers
The blade scraper, sometimes called plow wiper, is made from two thin flat strips of Delrin that
rub against the top and bottom of the blade to remove residue as the blade is running. It is located
on the drive side top of the cutting blade. The blade scraper must be centered on the blade to insure
that all residue is removed from the blade. Loosen the two set screws holding the wipers in place
and move them as needed to center the scraper on the band blade.
Direction of Blade Travel
Figure 7. Blade scraper - Hydraulic Machines
The scraper must be adjusted so it makes firm contact with the blade as the blade enters the
point of the scraper. The top strip is hinge mounted so that it can be moved away from the
blade. To adjust the scraper move the lower scraper strip up until it touches and causes
approximately 1/8 inch deflection of the cutting blade. Then rotate the upper scraper strip

Slicer/Applicator
down until it just contacts the blade. Firmly tighten both thumbscrews. Figure 7 shows a blade
scraper that is properly adjusted.
Check the blade scraper daily for noticeable wear. It should be replaced before wear becomes
excessive and wiping efficiency suffers. If uneven wear occurs, trim the edges of the scraper.
Blade Guide Maintenance
The blade guide should be checked for wear every 100 hours using the blade guide maintenance
tools furnished with each new machine. It should be checked for chips or cracks at every blade
change and replaced if any are present.
NOTE: It is important that the condition and wear of the blade guide be checked regularly.
Excessive wear of the blade guide reduces both the slice quality and the yield.
Blade Guide Maintenance Tools
A set of three Blade Guide Maintenance tools is included with each new slicer. One tool is a
scraper for cleaning the slot in the blade guide. The other two are for checking the blade guide
slot for excessive wear. It is important to check the blade guide if slice placement accuracy or
yield is affected. A worn slot may be the cause. The tools are shown below. Each tool has a
blue plastic handle.
Slot Scraper
The blade guide scraper (1028659) is for cleaning the blade guide slot during the
sanitation process. Simply insert the blade of the scraper into the slot and move it back
and forth along the entire length of the slot. It should move freely from one end of the
blade guide to the other. If an obstruction is met use care in dislodging it as the blade
guide is hardened steel and subject to cracking. You may wish to consult a Grote Service
Representative if the obstruction cannot be easily dislodged.
Slot Width Checking Tool
The "width" wear checking tool (1028660) is for checking the width of the blade guide
slot for excessive wear. Use the tool by attempting to insert the blade of the tool into the
slot of the blade guide. The blade of the tool is thicker than the standard slot width so that
SS-10.DOC:1/26/2007 11:08 AM
Figure 8. Blade Guide Maintenance Tools.
Grote Company
12
Slicer/Applicator
if the tool inserts easily into the slot the blade guide is worn excessively and may need to
be replaced. Check the blade guide along the entire length, especially in the region where
the food product has been passing across the guide.
CAUTION: The tool will not insert into a new blade guide. Do not force this tool into
the slot as damage to the guide may result.
Slot Depth Checking Tool
The "depth" wear checking tool (1028661) is for checking the depth of the blade guide slot
for excessive wear. Use the tool by inserting the blade of the tool into the slot until it
touches the bottom. If the notch in the tool inserts beyond the top edge of the blade guide
the blade guide slot is worn excessively and the blade guide may need to be replaced.
Check the blade guide along the entire length, especially in the region where the food
product has been passing across the guide.
Blade Guide Adjustment
The blade guide must be adjusted so the band blade runs smoothly through the entire length of the
slot in order to get good slice quality.
NOTE: Check the adjustment where the blade both enters and leaves the blade guide slot. Verify
that the blade is not too loose and does not contact the edges of the slot.
Use the following steps to adjust the blade guide.
Figure 9. Blade Guide.
1. Loosen the four mounting bolts for the blade guide.
2. Check the blade tracking to make sure that it is correct.
3. Verify that the welded joint of the blade is not in the blade guide slot and hand tighten the
blade guide mounting bolts.
4. (See Figure 9) Adjust the blade guide forward or backward until the blade clearance on one
end is between 0.001" and 0.010" (approximately 1/2 of the band blade thickness). Snug the
bolts on that end.
SS-10.DOC:1/26/2007 11:08 AM

Slicer/Applicator
5. Repeat the procedure on the other end of the blade guide. Snug these bolts also.
6. Repeat the above two steps until both ends of the blade guide are properly adjusted. Tighten
the blade guide bolts.
7. Check the blade tracking. If the blade is not tracking properly, the adjustment of the blade
guide was done incorrectly. If this happens, the blade guide must be moved away from the
blade and tracking must be corrected before the blade guide adjustment procedure can be
repeated.
8. Reinstall the water applicator pad, rotate the plow wipers into position, and replace the
guards on the machine.
(Opt) Quick Disc Blade Guide Adjustment -
1. Loosen the two threaded handles located beneath the exit guard by turning them
counterclockwise (See Figure 10). Push the two handles forward towards the entry
side of the slicer to release the pins from the hold-down slides.

On belt drive slicers, the belt that drives the blade pulley should be checked once a month for wear
and proper adjustment. Remove the belt cover and examine the belt. If it is glazed or cracked,
replace the belt. Check the tension in the belt and if it needs changing loosen the mounting bolts for
the blade motor and adjust the tension.
Product Holders
Height Adjustment
The product holder height is the clearance between the bottom edge of the product holder and
the tip of the band blade. This distance should be no less than 1/32" (0.8 mm) and no more than
1/16" (1.6 mm). If there is not sufficient clearance, slice quality will suffer. To check the
clearance, pull the product holder box pull pin and move the product holders across the blade.

The following steps are used to adjust the product holder clearance. On split-head
machines each cluster must be adjusted separately.
Figure 14 shows the adjustment bolts for the product holder clearance and Figure 12
shows the proper height adjustment.
1. Install the product holders in the slicer and release the pull pin. Swing the holders
across the blade guide.
2. Loosen the hex head cap screws in the adjustment jack screw.
3. Raise or lower the product holder box by turning the adjustment jack screws until
the clearance between the bottom of the product holder and the tip of the band
blade is between 1/32" (0.8 mm) and 1/16" (1.6 mm).
4. When the product holder height is properly adjusted, tighten the hex head cap
screw.
5. Reinsert the pull pin and the adjustment is complete.
6. Repeat the above procedure for all product holder boxes.

Product Holder Height Adj -
The height adjustment for All-Electric Slicers is similar to the Hydraulic Slicers. Each
slicing head must be adjusted using two jack bolts on each side at the top of the product
holders. The jack bolts rest on a support block welded to the frame (See Figure 13).).
1. Install the product holders in the slicer and release the pull pin. Swing the holders
across the blade guide.
2. Loosen the hex head cap screws in the adjustment jack screws.
3. Raise or lower the product holder box by turning the adjustment jack screws until
the clearance between the bottom of the product holder and the tip of the band
blade is between 1/32" (0.8 mm) and 1/16" (1.6 mm).
4. When the product holder height is properly adjusted, tighten the hex head cap
screws.
5. Reinsert the pull pin and the adjustment is complete.
6. Repeat the above procedure for all product holder boxes.
All-Electric Slicers
Alignment
The location of the product holder mounting brackets determines where the slices will be
applied on the conveyor. Product holders must be mounted directly over the area on the
conveyor where the slices are to be placed. The following steps should be used to adjust the
alignment of the product holders.
1. With the product holders still in the slicer, loosen the bolts on the product holder
mounting blocks.
2. Align the product holders so that the slices will fall in the proper place on the
conveyor. This adjustment is very important when applying slices to targets.
3. Tighten the bolts when the product holders have been properly aligned.
Pivot Point -
The product holder pivot point may need to be adjusted when product holders larger than 5" are
used. If the stroke length cannot be made long enough for the slicer to cut completely through
the product, change the pivot point to the extended position. Move the pivot point back to the
original position when the smaller product holders are placed back in the slicer. See Figure 14.

3. Remove the pivot bolt and pull the insert (pivot shaft, roller bearing and inner-race
spacer) out of the pivot hole from the outside.
4. Move the pivot block to the extended position and reinstall the insert. Tighten the
pivot bolt into the insert.
5. Tighten the adjustment jack screw and the hex head cap screw. Place the remaining
bolt in the exposed hole on the top of the frame.
6. Adjust the height of the product holder box, the stroke length, and the stroke starting
point.
7. On multiple split-head machines, the lock pin assembly for heads 2, 4, and 6 must be
moved to the extended position whenever the product holder box is moved to the
extended position. Also adjust the roller arm of the limit switch mounted on the lock
pin assembly so that it is tripped near the end of the slicing stroke.
Slice Stroke Adjustment
Check the adjustments of the stroke length and stroke starting point by running at a very slow speed.
The motion of the product holder should be slow enough to allow the relative positions of the blade
and the product holder to be seen. Readjust as necessary until the stroke is centered over the blade
with the proper stroke length

Stroke Length
Because the stroke length determines the distance that the product holder travels during the
slicing stroke, it needs to be adjusted whenever a different size product holder is installed in the
slicer. Keep distance as short as possible to minimize the time required to perform the slicing
and return motions. The product holder should have about 1/8" (3.2 mm) movement before the
front edge of the product holder crosses the blade. The back edge of the product holder should
go approximately 1/8" (3.2 mm) past the blade. Figure 15 shows the location of the stroke
length adjustment.

Figure 14. Stroke Length Adjustment.
Adjust the stroke length by loosening the two socket head cap screws on the offset crank and
then moving the offset. Increasing the offset makes the stroke length longer and decreasing the
offset makes it shorter. Moving the adjustment by one tooth will change the stroke
approximately 1/2" (1/4" on either side of the product holder). Tighten the socket head cap
screws before starting the machine.
(Opt) Two-Position Stroke Adjustment -
All-Electric Slicers
Two pull pin positions on the side of the cluster box allow a quicker means of adjusting the
stroke length. Placing the pull pin in the upper locating hole, will increase the stroke length
approximately 25 mm.
Stroke Starting Point
Adjusting the stroke length provides the proper amount of product holder travel but the stroke
needs to be centered over the blade. The stroke starting point adjustment centers the slicing
stroke directly over the band blade by changing the length of the connecting rod between the
offset crank and the product holder box. This adjustment must always be checked after the
stroke length has been changed.
(See Figure 15) Adjust the stroke starting point by first loosening the jam nut of the connecting
rod and then releasing the pull pin. Turn the rod end in to move the starting and ending
positions toward the offset crank. Turn the rod end out to move the starting and ending
positions away from the offset crank. One complete turn of the rod end will move the starting
point approximately 1/8" (3.2 mm). Insert the pull pin when this adjustment is complete.

Stroke Speed
Hydraulic Slicers - The speed of the slicing stroke is adjusted with the hydraulic flow-control valve
on the side of the slicer frame.
All-Electric Slicers - The speed of the slicing stroke is adjusted with the key pad on the operator
interface.
Stroke speed should be adjusted so that the cluster moves across the blade at a speed matching that
of the conveyor. Variations to this may be desired and can be determined upon actual application.
The speed of the overall stroke cycle must be fast enough to allow the cluster to be at the original
starting position when it is time to start the forward motion of the next cycle.
The maximum recommended stroke speed is dependent upon the stroke length. Longer stroke
lengths require more mechanical travel of the cluster assembly thus limiting the allowable number of
strokes per minute. The following table lists the maximum strokes per minute for the listed stroke
lengths.
Stroke Length
in Inches
2.0 1.5 5.3 176
2.5 2.0 5.0 168
3.0 2.5 4.8 160
3.5 3.0 4.6 152
4.0 3.5 4.3 144
4.5 4.0 4.1 136
5.0 4.5 3.8 128
5.5 5.0 3.6 120
6.0 5.5 3.4 112
Note: The maximum rating of the slicer is 176 strokes/minute.

Other factors that affect the stroke speed are:
1. Shuttle Conveyor - Slicers equipped with a shuttle conveyor should not exceed 120
strokes/minute.
2. Quick Return - The quick return feature becomes largely ineffective at speeds above 70
strokes/minute.
3. Product Pusher - Slicers equipped with a product pusher should not be run at speeds above
140 strokes/minute.

First, loosen the two hex head bolts in the side of the thickness tray mounting assemblies. The slice
thickness tray pivot point can then be lowered or raised by turning the adjusting bolts located in the
top of the adjustment blocks. When the tray is at the desired height, it is parallel to the top surface
of the blade guide. Verify that the thickness tray is level at this height and tighten the hex head
screws on the side of the adjustment blocks.

Adjust the slice gap, see Figure 17, using the following table, so that there is enough room between
the thickness tray and the blade guide for the slices to pass through. Some variance from the values
in the table may be necessary to obtain closer accuracy on very thin slices or to prevent thicker
slices from "hanging up" on the blade guide.
