OPERATION INSTRUCTIONS
IMPORTANT: DISCONNECT THE AIR LINE IN ACCORDANCE WITH OSHA’S LOCKOUT/TAGOUT PROCEDURES
(29 CFR 1910.147) BEFORE SHARPENING BLADES. DISCONNECT THE AIR LINE IN ACCORDANCE WITH OSHA’S
LOCKOUT/TAGOUT PROCEDURES (29 CFR 1910.147) BEFORE PERFORMING ANY REPAIR OR MAINTENANCE.
6.2 With the vacuum activated, insert the pilot pin
(item 1) into the anus of the bird. The entire anus
ring should be enclosed by the blade, and the
skin of the bird should be sucked up around the
entire cutting edge of the blade. Refer to Figure
2.
Anus
Refer to pages 4 and 5 for all referenced items.

2 Attach the 8 ft. water tube (1323019) to connector
assembly (item 13).
3 Attach the air hose (1323011) to quick connect coupling (item 31).
4 Attach trigger control hose (1323015) to tube connector (item 10).
5 Each day, before you begin operation, go through
the following checklist:
5.1 Make sure that the Model VC moves freely on
its balancer.

Pilot pin
Rosebud

6.3 While vacuum is holding the skin upward, pull
the trigger back fully and allow the blade to rotate. Move the blade gently forward into the bird
about 1/2 to 3/4 of the length of the blade. Do
not apply pressure on the bird until the blade is
rotating. Refer to Figures 3 and 4.
Proper Method
5.2 Make sure that you are wearing a steel mesh
safety glove on the hand that will not be operating the Model VC.
6 Making the cut:
6.1 Pull the trigger until it touches the round trigger
on the motor. This activates the vacuum at the
blade. Refer to Figure 1.

6.4 A gentle motion with a downward pressure will
cut the bird properly. Forcing the blade will
leave all or part of the rosebud in the bird. Do
not force the blade or stab the bird with the
blade. Do not let go of the trigger after fully depressing it. The blade will turn only a few revolutions and will shut off automatically (it will
not cut the intestines). The vacuum will remain
sucking as long as the trigger is held in the fully
depressed position.

center of the bird. If the blade is directed toward

6.6 While still holding the trigger, pull the blade
slowly out of the bird. The vacuum will hold the
anus and the fecal material long enough for the
operator to either grab the vent and move it away
from the hole or to move the vent away from the
hole with the gun.

6.7 Release the trigger. The vacuum will shutoff
and release the vent into the operators hand so
that it can be pulled out of the carcass and laid
gently over the side of the carcass or it will release the vent over the side of the carcass if the
vacuum pulls the vent completely out of the carcass.

6.8 After releasing the vent, the operator must aim
the blade at the trough before reaching the next
bird. Depress the water flush lever to flush out
all materials from the blade before attempting to
cut another bird. Do not flush waste material on
the birds. The water will not flush out the blade
unless the vacuum trigger is in the rest position.
When both vacuum and water triggers are activated, all water will be sucked up the vacuum
tube sending all waste material to the collector
tank.

6.9 When a bird has fecal material on the outside of
the carcass, it can be washed off with the vent
gun before cutting the bird. Be sure that the
blade has been sufficiently flushed into the
trough before attempting to wash off any bird.
Do not attempt to wash the bird after cutting into
the carcass.

MAINTENANCE INSTRUCTIONS
IMPORTANT:
material and make it impossible to hold a
sharp edge. Return to Jarvis for regrinding.
DISCONNECT THE AIR LINE IN ACCOR-
DANCE WITH OSHA’S LOCKOUT/TAGOUT PROCEDURES
(29 CFR 1910.147) BEFORE PERFORMING ANY REPAIR OR
MAINTENANCE.
Refer to pages 4 and 5 for all referenced items.
4 MODEL VC BLADE DISASSEMBLY:
Wear cut protective gloves when handling blades.
1 DAILY:
1.1 Check to see that the Model VC is getting
enough lubrication. Each one or two pulls of the
trigger should produce one drop of oil in the
sight dome. If required, adjust the oil flow.
1.2 Make sure that the oil in the lubricator is up to
the full mark. Use USDA approved Jarvis Air
Mist Lubricator Oil. Do not use mineral oil.
4.1 While holding base of blade (item 2) in place,
use special wrench (part number 8327001) to
loosen pilot pin (item 1).
4.2 Remove blade (item 2).
4.3 Inspect blade (item 2) for wear and sharpen if
necessary.
5 MODEL VC BLADE ASSEMBLY:
Wear cut protective gloves when handling blades.
2 WEEKLY:
5.1 Place blade (item 2) over cutter shaft (item 3).
2.1 Add four to five shots of grease to grease fitting
(item 14). Use USDA approved Jarvis 1315
White Grease.
5.2 Assemble pilot pin (item 1) through blade (item
2).
5.3 Tighten pilot pin (item 1) hand tight into cutter
shaft (item 3). The pilot pin will automatically
tighten with use of the tool.
3 WHEN NECESSARY:
Wear cut protective gloves when handling blades.
3.1 Sharpen the blade (item 2) when the blade becomes difficult to push into the carcass, or when
the cutting produces contamination.
6 MODEL VC DISASSEMBLY:
6.1 Follow steps and procedures 4.1 and 4.2.
3.1.1 Place a sharpening stone on the cutting
angle of the blade and activate the tool.
Continue to desired sharpness. If this action
rolls the cutting edge inward, hold a small
steel on the inside edge of the blade.
6.2 Unscrew the knurled ring on shaft housing assembly (item 4).
3.1.2 Repeat the process until the blade is sharp.
6.4 Place a pin through the cross hole in the cutter
shaft (item 3) and hit pin with a hammer on the
proper end to turn it counter--clockwise.
WARNING: pin may fly out of unit. Protect
yourself and other employees when disassembling this part.
3.1.3 If the angle of the blade becomes too short
or when the cutting edge has excessive
nicks, the blade must be reground. Do not
heat the cutting edge. Heat will anneal the

TROUBLESHOOTING
REMOVE ANY MALFUNCTIONING TOOL FROM SERVICE
PROBLEM
SOLUTION
MOTOR RUNS WHEN THE TRIGGER IS RELEASED.
Refer to page 4 for referenced items.
CHECK THE AIR MOTOR TRIGGER (ITEM 39).
If the trigger flops in and out or stays depressed when touched,
it is malfunctioning. Remove the air inlet valve (item 32) and
valve stem pin (item 34). With long nose pliers, remove valve
pin (item 35). Clean pins until their surfaces are smooth. Clean
out the deepest hole in the pistol grip handle (item 22) with a drill.
Rotate the drill by hand. Do not increase the size of the hole.
CHECK THE O--RING LOCATED IN AIR INLET VALVE (ITEM
32).
Remove the retaining ring, screen, spring, and poppet from the
air inlet valve (item 32). Check for an o--ring on the poppet. If
there is no o--ring on the poppet, check the inside of the air inlet
valve. Reassemble the o--ring to the poppet and reassemble the
air inlet valve.

clockwise until the blade on the vent gun turns off. Continue to
adjust until desired number of blade rotations is accomplished.
CHECK AIR PILOT VALVE (ITEM 60).
Remove four screws and cover on air pilot valve (item 60) carefully. Check rubber diaphragm. If the rubber diaphragm has a
hole, it must be replaced (part number 3343009).
CLEAN VENTURI ASSEMBLY (ITEM 54).
If the regulator has no range of adjustment, clean the venturi assembly. Remove tube connector (item 53). Clear the small hole
in the silver pin with a small diameter wire. Do not increase the
size of the hole.
BLADE DOES NOT ROTATE WHEN TRIGGER IS PULLED.
Refer to pages 4 and 5 for referenced items.
CHECK THE AIR SUPPLY.
The air pressure gage (item 62) must show pressure.
CHECK THE VACUUM.
When trigger is pulled, there is suction at the blade. If there is
no suction at the blade, the air supply to the tool is shut off.
CHECK VANES (ITEM 17).
If air is exhausting through the butt of the pistol grip handle, release trigger and turn blade 1/2 revolution. Pull trigger. If the
Model VC runs properly now, it is an indication of sticky vanes
(causes: wrong oil, dirt in slots, lack of oil). Disassemble motor,
clean rotor, and check length of vanes (they should be .002
shorter than the length of the rotor). Check rotation of each bearing (they should rotate freely).
WATER VALVE LEAKS.
Refer to page 4 for referenced items.
WATER VALVE LEAKS AT TIME OF INSTALLATION.
Check for metal fragments from the threaded pipe. Remove water tube from tube connector (item 13). Remove tube connector
(item 13). Check water valve (item 12) for debris, and remove
debris with small pointed object. Do not damage spring or seal.
WATER VALVE LEAKS AFTER CONSIDERABLE USE.
Replace water valve (item 12).
