INSTALLATION INSTRUCTIONS
ALWAYS DISCONNECT THE HYDRAULIC HOSES
AND SHUT THE POWER OFF IN ACCORDANCE
WITH OSHA’S LOCKOUT/TAGOUT PROCE-
DURES (29 CFR 1910.147) BEFORE PERFORM-
ING ANY REPAIRS OR MAINTENANCE.
Refer to Figure B on page 5 for referenced items unless
otherwise noted. Use Figure D on page 7 and Figure 1
on page 10 as a guide for wiring and hose connections
to the hydraulic power unit.
1 Install the hydraulic power unit overhead or on the
floor behind the work station.
1.1 Avoid excessive height and long pipe runs.
1.2 Locate the equipment in a clean, dry work area
and provide adequate space on all sides of the
unit for maintenance accessibility to all compo-
nents.
2 Remove breather filler cap (item 9, Figure D, page
7) and fill the power unit oil reservoir with a USDA
approved premium grade hydraulic fluid (viscosity
index 200 SUS at 100°F/46ISOat40°C). Never
run the power unit without oil.
3 Install the balancer, Jarvis part number 4042004,
above the work station.
3.1 If the operator has to move with the chain line,
install the balancer on a trolley. The trolley
should have sufficient travel to allow the opera-
tor to reach the entire work area.
4 Suspend the 1000--FS from the balancer.
4.1 Adjust the balancer to the operators preference.
5 Make all necessary wiring connections. All wiring
must be done in accordance with national, state
and local electrical codes. Refer to wiring diagram
inside the electrical control box cover.
5.1 Domestic power units require three--phase, 60
hertz, 230/460 volts to the motor and 115 volts,
single--phase to the electrical control box.
Please check the wiring diagram inside the cov-
er of your electrical control box for other volt-
ages and frequencies.
5.2 Equip the power unit with a switch at the opera-
tors station to facilitate shut down in case of
equipment failure.
5.3 Plug the wire and plug assembly (item 71) on the
1000--FS saw into the twist lock plug outlet
(item 5, Figure E, page 8) on the electrical con-
trol box.
6 Make all necessary hose connections. Connect the
hydraulic pressure and return lines.
6.1 Connect the quick connect socket (item 82) on
the 1000--FS saw to the return line quick connect
plug (item 25, Figure D, page 7) of the power
unit. Connect the the pressure line quick con-
nect socket (item 24, Figure D, page 7) on the
power unit, to the quick connect plug (item 80)
of the 1000--FS saw.

OPERATION INSTRUCTIONS
1 Connect all hydraulic hoses.
2 Plug the 1000--FS saw into the electrical control box
twist lock plug outlet.
3Each day, before you begin operation, go through
the following checklist:
3.1 Make sure that the1000--FS moves freely on the
balancer.
3.2 Make sure that the dual anti--tie down control
handles (the front and rear handles) are working
correctly. Depress each trigger separately and
the tool should not start. Depress both triggers
simultaneously (within one second of each oth-
er) and the tool should start. Release either or
both triggers and the tool should stop. If the tool
malfunctions, remove it from service and report
the problem to your supervisor immediately.
Always use two hands when starting and stop-
ping the tool. Continue holding the tool firmly
with two hands until the saw blade comes to a
complete stop.
4 Making the cut:
4.1 Position the 1000--FS.
4.2 Depress both triggers simultaneously to start the
motor and make the cut. Always use two hands
when starting and stopping the tool.
4.2.1 Make the cut with a firm, steady motion. Do
not exert excessive pressure on the
1000--FS, but rather, guide the saw through
the cut.
4.2.2 The carcass should be supported by a back
board to stabilize and prevent it from turn-
ing while making the cut. RefertoFigure2
as a guide.
4.3 When the desired length of cut is reached, re-
lease either or both triggers. This will stop the
blade from rotating. Continue holding the tool
firmly with two hands until the saw blade
comes to a complete stop.
4.4 Withdraw the 1000--FS from the carcass.
4.5 Unplug the 1000--FS saw.
Place board to
support and prevent
carcass from turning
Rail

MAINTENANCE INSTRUCTIONS
Refer to Figures A -- C on pages 4 -- 6 for referenced items
unless otherwise noted.
IMPORTANT: ALWAYS DISCONNECT ALL HY-

1.2 Check all fittings for leaks and tighten or replace
as necessary.
1.3 Inspect all electrical cords, cord connectors and
plug assemblies over their entire length for cuts
and abrasions and replace as necessary.
1.4 Check the oil level gage (item 21, Figure D, page
7) on the hydraulic power unit and fill oil reser-
voir if necessary.
1.4.1 Change hydraulic fluid and filter as neces-
sary. Fill the oil reservoir with USDA ap-
proved premium grade hydraulic fluid (vis-
cosity: 200 SUS at 110°F/46ISOat38°C).
Burnt smelling or foamy fluid should be re-
placed immediately.
1.5 The 1000--FS is equipped with dual anti--tie
down control handles (the front and rear han-
dles). Check for the correct operation of the dual
anti--tie down control handles daily:Depress
each trigger separately and the tool should not
start. Depress both triggers simultaneously
(within one second of each other) and the tool
should start. Release either or both triggers and
the tool should stop. If the tool malfunction, re-
pair it or remove it from service immediately.
Always use two hands when starting and stop-
ping the tool. Continue holding the tool firmly
with two hands until the saw blade comes to a
complete stop.
Note: The power supply must be connected to per-
form the above operation only.
1.6 Four times (4) per day, add Jarvis 1315 White
Grease to the grease fitting (item 12) located on
gear housing (item 13).
1.7 Thoroughly clean the tool at the end of the day/
shift and spray with an approved mineral oil for
overnight storage.
2 WEEKLY:
2.1 Disassemble, clean and inspect gear housing as-
sembly. Refer to sections 6 and 7 as a procedur-
al guide.
3 AS NECESSARY:
3.1 Clean and inspect circular blade. Refer to sec-
tions 4 and 5 for blade removal and installation
procedures.
3.2 Disassemble, clean and inspect motor housing
assembly and motor adapter. Refer to sections
8 and 9 as a procedural guide.
3.3 Replace the power unit oil filter (item 12, Figure
D, page 7) at regular intervals.
Note: The hydraulic motor will require only occasional
rebuilding. Do not rebuild the hydraulic motor -- send it
back to Jarvis to be rebuilt.
4 CIRCULAR BLADE REMOVAL:
4.1 Remove hex head screw (item 43) and lock
washer (item 42). Insert an allen wrench or
screwdriver through one of the outer holes in
blade to prevent blade from turning.
4.2 Remove blade retaining flange (item 41).
4.3 Remove circular blade (item 40).
4.4 Inspect all parts for wear and replace if neces-
sary.
4.4.1 Inspect circular blade for wear and sharpen
or replace as necessary.
5 CIRCULAR BLADE INSTALLATION:
5.1 Reverse steps and procedures outlined in section
4. See notes below. Refer to figure 3 on page 13
as a guide.
5.1.1 To ensure proper fit and safe operation, the
hub of the saw blade (item 40) must face to-
ward and fit securely on the extended lip of
the shaft and pin assembly (item 2).
5.1.2 The holes on the blade retaining flange
(item 41) must align with the four dowel
pins (item 1) on the shaft and pin assembly
(item 2). Make sure the notched areas on the
blade are aligned with dowel pins (item 1).
