OPERATION
OFF/ON SWITCH
All J-saw machines are equipped with a manual starter with low voltage, dropout protection
and a limit switch. When the machine frame reaches the end of its down travel it contacts the
limit switch, turning off the machine.
HYDRAULIC CONTROL
The hydraulic control cylinder mounted on the rear of the machine is operated by a control
valve mounted on the front of the machine head. To close valve, turn the control to the right.
When the valve is completely closed, the frame will remain stationary at the desired position.
To open valve, turn control to the left. Opening of the valve will control the speed of descent
of frame (or head) and does not control frame weight. This control is mainly used in cutting
pipe or thin-walled tubing, structurals, etc., to prevent plunging of the saw blade.
VISE
The vise can be positioned straight for a 90º cut or at any angle to 45º. The vise swivel jaw
adjusts automatically to any position of the stationary jaw.
VISE QUICK-RELEASE
Consists of the vise half-nut, vise lift, lift handle and a sliding hold-down block to which the
swivel jaw is attached. Move the vise lift handle toward front of the machine to disengage the
vise nut from the vise screw; this allows the swivel jaw to be moved freely. Move the lift
handle towards the rear of the vise to engage the vise nut when clamping.
VISE HANDWHEEL
Used to open and close the vise jaws…vise nut must be fully engaged. Turn handwheel
counterclockwise to open the vise, clockwise to close the vise.
BLADE TENSION HANDLE
Turn the screw handle clockwise as tight as possible. Check every eight operating hours and
retighten to compensate for possible stretching of blades. Consult your blade manufacturer
for the proper PSI tension.
GUIDE ARMS
Loosen the handle on the left guide arm to slide arm along the top of the frame. Guide arms
should be set as close as possible to the work, without interfering.
STOCK STOP GAUGE
Consists of a stock stop assembly and a mounting bar installed in the tip-off block on front of
the machine. The stop assembly can be moved along the bar to indicate correct length for
duplicate cuts. Stock stop rod has a cap screw in the end for making fine adjustments. Turn
rod to extended position (rotated to the right) when measuring stock, and retract the rod
(rotate to left) when cutting.
OPERATING INSTRUCTIONS

6/02
13
1. Raise frame and close feed cylinder valve to hold frame in elevated position.
2. Loosen the vise nut and open the vise. Place work in vise and slide the vise swivel jaw
against the work piece. Engage the vise nut and tighten the vise screw to clamp the work
securely.
3. Slowly open feed cylinder valve and lower the frame until the blade almost touches the
work. CAUTION: IF BLADE SHOULD REST UPON THE WORK BEFORE MOTOR IS
STARED THE BLADE TEETH CAN BE DAMAGED- IF BLADE IS DROPPED ONTO THE
WORK THE BLADE MIGHT BREAK. MAKE SURE BLADE IS PROPERLY BROKEN IN
PRIOR TO CUTTING.
4. Move the adjustable guide arm as close as possible to the work to provide maximum
blade rigidity.
5. Check the blade tension. Consult blade manufacturer for proper PSI tension.
6. Turn coolant valve on (wet machines only). CAUTION: DO NOT OPERATE MACHINE
WITHOUT SUFFICIENT COOLANT IN TANK. COOLANT MUST BE WATER-SOLUBLE
DO NOT USE OIL.
7. Check blade speed for material you are cutting. Refer to blade manufacturer for proper
speeds for the material you are cutting.
8. To change blade speed, loosen thumbscrew on right end of machine and raise the pulley
guard. Move drive belt to proper grooves in both pulleys for desired blade speed, (see fig. 3).
Replace guard.
9. Start motor.
10. Open feed cylinder valve to the proper setting. “Proper” setting depends upon type of
material, hardness and thickness of stock and desired accuracy and finish. Soft materials
require less feed than hard materials. Thin cross-sections require less feed than solid cross-
sections. Generally, reduced feed pressure will result in a straighter more accurate cut.

BLADE SELECTION
Saw blades should be selected by choosing the blade that will give the best results at the
lowest cost. Type of material and the speed at which it must be sawed determine the choice.
Listed below are general factors affecting blade selection.
1. Blade Type.
(a) Carbon Steel – Can be used to cut all types of ferrous, non-ferrous and
composition materials except alloys containing high percentage of chrome and
nickel. Limiting factor: low resistance to heat.
(b) Bi-Metal – Designed for cutting ferrous metals in production cut-off
applications. Developed to saw high alloy materials that cannot be cut
economically by other means. Can be operated at higher speeds and greater
feed pressures than carbon steel blades.
2. Tooth Style.
(a) Standard – Zero degree rake angle and full round gullets. Best suited for
cutting ferrous and non-ferrous materials.
(b) Skip Tooth – Basically the same as standard except for more widely spaced
teeth. Provides added chip room when cutting non-ferrous materials.
(c) Hook Tooth – Similar to skip tooth except teeth have positive rake. Effective
in sawing non-ferrous metals and large ferrous sections when heavy feed
pressures are required. Fast cutting.
3. Tooth Spacing.
Tooth spacing is determined by hardness of material and/or the cross-section.
The harder the material, the more teeth per inch. Thin cross-sections require
more teeth to avoid straddle. Rule: at least 3 teeth in contact with work.
4. Tooth Set.
(a) Raker – Most widely used. Consists of a repeated pattern of one tooth set
left, one right and one tooth straight. Recommended for production cutting
where material is of uniform size, shape and type.
(b) Wavy – Has groups of teeth set alternately to the left and to the right forming
a wave-like pattern. Used for cutting thin stock or where the work varies such
as in pipe, angles, channels and extrusions.
BLADE REMOVAL
1. Raise frame a few inches above bed and close feed cylinder valve to hold frame up.
2. Remove necessary guarding and blade cleaning brushes.
3. Turn blade tension screw counterclockwise and pull idle wheel toward center of machine.
4. Push blade down out of blade guides and remove blade from machine.

1. Raise frame a few inches above bed and close feed cylinder valve to hold frame up.
2. Remove necessary guards and blade cleaning brushes.
3. Turn blade tension screw counterclockwise and pull idle wheel toward center of machine.
4. Grasp blade in center forming two loops. From rear of machine place blade loops under
wheels and rest the near portion on right front blade guard. CAUTION: BE SURE TO
WEAR GLOVES WHEN HANDLING BLADES.
5. Push blade up into blade guides. CAUTION: BE AWARE OF HYDRAULIC & COOLANT
LINES.
6. Fit blade up against flanges of the idle and drive wheels and tighten tension screw enough
to hold blade in place. Depress side of blade near rear blade guard to hold blade on
wheels while tightening tension screw.
7. Check to see that the blade is positioned correctly and tighten screw. Consult blade
manufacturer for proper PSI tension.
8. Install blade cleaning brushes and guards that were removed earlier.
BLADE TRACKING ADJUSTMENT
Saw blade should track on each wheel with the back of blade up to, but not riding on, the
wheel flange. Adjust as follows:
1. Idle Wheel.
Open top cover on left end of machine to gain
access to idle wheel. Idle wheel is mounted on a
slide block, which contains the blade height
adjustment screws. To raise the blade, loosen the
two screws toward center of machine (A, Fig. 4)
one-half turn and tighten the other two screws (B)
one-half turn. Be sure tension screw (C) is properly
tightened. Reverse procedure to lower blade. Care
must be taken not to over adjust. Check by running
machine after each adjustment.
2. Drive Wheel.
(a) To raise the blade, loosen two cap screws (A, Fig. 5) and
tighten screws (B and C). All four screws must be turned
equally and in small increments (about ½ turn) to avoid over-
adjustment; check by running machine after each adjustment.
(b) To lower blade, reverse above procedure – loosen screws
(B and C) and tighten screw (A).

BLADE GUIDE ADJUSTMENT
NOTE: The following instructions are for one
guide arm; procedure is same for both. Left hand
guide arm is shown in Figure 6.
1. Loosen nut (A, Fig. 6) and turn eccentric axle (B)
until there is no light gap between rollers and
blade…do not pinch the blade. Tighten nut (A).
2. Vertical and radial adjustment is provided by the
clearance in the guide mounting holes (C, Fig. 6).
This allows squaring of the blade to the bed, and
holding the blade in the natural blade line.
3. Proper guide adjustment may require adding or
removing washer (shims) (D, Fig. 6) for correct
bearing height (E, fig. 6)
FRAME BALANCE SPRING ADJUSTMENT
To check for proper balance spring adjustment, lift frame at eh handle with an extension type
scale (fish scale). Frame should weigh 12-15 pounds; if no, adjust by turning nut on the tension
screw at bottom of spring.
FEED CYLINDER BLEEDING
Air trapped in the hydraulic cylinder can cause the down feed of the machine head to be
erratic or “bouncy”. Before taking corrective steps observe CAUTION.
CAUTION: UNDER NO CIRCUMSTANCES SHOULD THE HYDRAULIC TUBING CONNECTIONS
BE LOOSENED OR DISCONNECTED WITH THE MACHINE HEAD IN THE UP POSITION.
Bleed the hydraulic cylinder circuit as follows:
1. Place a long neck funnel in the oil cup (diameter of funnel neck must be almost the same
size of the fill cup.
2. Pour oil into the funnel. *Make sure there is a sufficient amount of oil in the funnel so that
air does not get drawn into cylinder.
3. With head feed valve open, raise and lower head about four times.
4. Pour more oil into the funnel.
5. Close head feed valve.
6. Raise head.
7. Open feed valve and lower head.
8. Repeat 5,6 & 7 several times.
9. Remove funnel.
