INSTALLATION INSTRUCTIONS

ALWAYS DISCONNECT THE POWER SUPPLY IN
ACCORDANCE WITH OSHA’S LOCKOUT/TAGOUT
PROCEDURES (29 CFR 1910.147) BEFORE PERFORM­ING ANY REPAIRS OR MAINTENANCE.

ALL WIRING MUST BE DONEIN ACCORDANCE WITH
NATIONAL,STATE AND LOCALELECTRICAL CODES.

1 Install the FS saw above the work station from a ba-

lancer. Jarvis part number 4042044 is available.

1.1 The saw should have enough travel to allow the
operator to reach the entire work area.

2

2 Install the hydraulic power unit overhead or on the

floor behind the work station.

2.1 Avoid excessive height and long pipe runs.

3 Wire the power unit. The power unit requires three

phase, 60 Hertz, 230/460 volts to the motor and
single phase, 60 Hertz, 115 volts to the control box.

4 Equip the power unit with a master pilot light switch

at the operator’s station. This will facilitate shut-

down in case of an equipment failure.

5 Fill the oil reservoir with a USDA approved pre-

mium grade hydraulic fluid (viscosity: 200 S.U.S. at
100° For46ISOat40° C). Never run the power unit

without oil.

page 10 of 12

6 Make all necessary hose connections. Refer to Fig-

ure E on page 8 for referenced items unless other­wise noted. Refer to Figure 1 as a guide.

6.1 For the air pressure line: Use tube to tube con­nector (item 7) to connect blue plastic tubing
(item 6) from air filter (item 9) to blue plastic
tubing (item 74, Figure B, page 5) from the port
marked “IN” or “2” on hydraulic manifold (item
64, Figure B, page 5).

6.2 For the air return line: Use tube to tube connec­tor (item 7) to connect yellow plastic tubing
(item 10) from street tee (item 13) to yellow
plastic tubing (item 75, Figure B, page 5) from
the port marked “OUT” or “1” on hydraulic
manifold (item 64, Figure B, page 5).

6.3 Connect the quick connect plug (item 78,Figure
B, page 5) from the hydraulic supply line con­nected to the hydraulic manifold port marked
“IN”, to the quick connect socket (item 24, Fig­ure D, page 7) of the supply line marked “A” on
hydraulic power unit.

6.4 Connect the quick connect socket (item 77, Fig­ure B, page 5) from the hydraulic return line
connected to the hydraulic manifold port
marked “OUT”, to the quick connect plug (item
23, Figure D, page 7) of the return line marked
“B” on hydraulic power unit

7 There are no adjustmentsto be made at the hydraulic

power unit for blade speed or hydraulic pressure.
The blade speed is a result of using the full output of
the pump and cannot be increased. The pump is set
to a maximum relief pressure of 2000 psi. During
operation, the pressure gage (item 26, Figure D, page

7) will only show the pressure required to make the
cut. The pressure gage should read approximately
300 psi with the saw running under no load.

OPERATION INSTRUCTIONS

ALWAYS DISCONNECT ALL HYDRAULIC AND AIR
HOSES AND SHUT OFF THE POWER SUPPLY IN
ACCORDANCE WITH OSHA’S LOCKOUT/TAGOUT
