Yes, the pressure regulator for the Hyd-Mech S-25A saw is specified as a Pressure Reducing Valve (PRV1). The descent speed is controlled by the Feed Force Limit, which can be adjusted by turning the knob clockwise until it bottoms and setting the pointer at "0".

With these points clearly in mind we have designed the HYD-MECH S-25A. Our goal is to change stock cut- off from a "necessary evil" to a money making and time saving part of your operation.

-Operator should keep a safe distance from all moving parts especially the blade and vises. -If not performing properly the machine should be stopped immediately and repaired by a qualified person. -No modifications to the machine are allowed without Hyd-Mech’s prior approval. Any approved modifications shall be performed by trained personnel.
VISE CYLINDERS To permit the S-25A to be shipped in a standard trailer, the three vise cylinders must be fully retracted, the hydraulic hoses disconnected, and the mounting brackets unbolted from the infeed table Fig. 1-3. The cylinder tube is then rotated around the cylinder rod so that the mounting bracket and tube are upside-down. This jaw is now pushed completely toward the fixed jaw letting the bracket rest on the infeed table.
HEAD RESTRAINT BAR The S-25A bandsaw is shipped with the head secured at the 45° position by a restraint bar and is wired down to the base to ensure that the head can not move in any direction during shipping. After the saw has been lifted into position, the head restraint bar must be removed along with the wire.
Fig. 1-9 Electrical junction block. HYDRAULIC OIL AND CUTTING FLUID The S-25A bandsaw is supplied with Valvoline 150-46 hydraulic oil. If it is necessary to change the oil to a different brand see the HYDRAULIC SECTION for an equivalent grade oil.
START-UP The S-25A control console has been designed to simplify the operation of the saw, to give the operator the ability to stop any function at any time, and to be able to control all the functions remotely. (See Fig. 2A-1) We can not overstress the importance of familiarizing yourself with the controls of the S-25A prior to starting the machine.
Page 10
EMERGENCY STOP This button will stop both the hydraulic and blade motors and BUTTON: de-energizes the MODE SWITCH. The head and shuttle motion will cease. The vises will remain as they are, but if closed, they will gradually lose gripping force. For this reason all long stock should be supported so that in this eventuality, it will not fall.
Page 11
FIXED VISE SWITCH: This switch is operative as long as the machine is supplied with power. Unlike the other function switches it is active when the MODE SWITCH is in NEUTRAL. The FIXED VISE SWITCH is wired this way to insure that the fixed vise will not release the work piece when switching between AUTO and MANUAL, or if the saw should shut down during a cut due to a motor overload.
Page 12
AUTO CYCLE DIAL: This knob rotates in a clockwise direction when the saw is running and the MODE SWITCH is in AUTO Fig. 2A-4. As it rotates it sends out control commands indicated on the dial. Whenever the head or shuttle motion is initiated, the dial will stop and wait for the motion to reach the end of its travel, and then it will resume its rotation.
SHUTTLE LENGTH CONTROL To adjust for desired stock for a production run,as shown in Fig. 2A-8, move the Adjusting block 'A' to the desired position along the scale. Fine adjustments can be made using the micrometer 'B'. The zero point on the micrometer is .250 inch.
Increasing the micrometer setting increases the part length, while decreasing the micrometer setting de- creases the part length. NOTE: Remember to reset the micrometer to exactly midscale at the end of each run. S-25A AUTOMATIC CONTROLS BLADE KERF Although blade thickness is stand-...
Variable pitch, bi-metal blades (like the 2/3 or 4/6 bi-metal blade supplied with the S-25A series saws) last much longer, cut faster, and more accurately than conventional carbon steel blades.
2.13 VARIABLE SPEED CONTROL Blade speed can be adjusted infinitely between 75 and 400 SFPM (Surface Feet/Minute). Adjustment should be made only when the blade is running. Clockwise rotation of handwheel “A” (Fig. 2B-1) increases the blade speed while counter clockwise rotation decreases the blade speed. Blade speed is displayed on an indicator located in the adjustment hand wheel.
2.14 USING THE SAW CUTTING PARAMETERS ON CHART A full size chart is mounted on the panel. The chart contains five steps for the operator to follow in order to achieve optimum performance of the saw. Fig. 2B-6 Saw cutting parameter door chart. As Example #1 we will use the CHART to set up the saw, for cutting 8"...
Page 18
2.15 Both effective material width and guide arm width are used in setting the saw. Guide arm width is the distance between the guide arms and is used in STEP 2. Effective material width, as determined here in STEP 1, can be thought of as the average width of material “seen”...
2.16 SIGNIFICANCE OF GAUGE READING: With the head down and yellow button depressed the (FEED FORCE “set” on manual control panel) FEED FORCE gauge indicates the setting of the FEED FORCE LIMIT. During cutting the gauge shows the actual force being applied by the blade to the workpiece. In typical cutting situations, the needle on the gauge will rise toward the preset FEED FORCE LIMIT and stabilize, usually at a lower level.
2.17 necessary, but remember that the optimum blade will cut most efficiently. Too fine a blade must be fed slower on wide material because the small gullets between the teeth will get packed with chips before they get across and out of the cut. Too coarse a blade must be fed slower because it has fewer teeth cutting and there is a limit to the depth of a cut taken by each tooth.
2.18 NOTE: About Material Hardness The Graph - Step 4, Fig 2B-8, illustrates blade speed curves for material hardness 20 Rc (225 Bhn) or lower. If the material is harder , use multipliers from the NOTE (near the bottom) of the Graph. For example, if the 5 diameter, 1045 Carbon Steel material, from the table above, had been hardened to 35 Rc (325 Bhn) then we must multiply the blade speed of 225 ft/min by .60.
Page 22
2.19 For Example #1, it is known from Step 3 that otimum blade pitch is 2/3, and from Step 4 that blade speed ,200 ft/ min. From the graph, Fig. 2B-10 the FEED RATE is determined in the following way: - On the horizontal axis (blade speed axis), find 200 ft/min.
2.20 CUTTING CONTROL SET UP EXAMPLES FOR EXAMPLES #2 AND #3 PLEASE GO TO THE SAW AND FOLLOW STEPS 1-5 ON THE CHART: Example #2 Material to be cut -Round Steel Tube SAE 4320 6" OD x 4" ID -Hardened to 35 Rc (325 Bhn) STEP 1 Effective Material Width: 4 1/2"...
Page 24
2.21 Example #3 Material to be cut -low carbon steel -2" x 2" tube x 1/4" wall -clamped in vises 12 pcs in a bundle (6" x 6") STEP 1 Effective material width: 5" (6" x 8") STEP 2 Feed Force limit for 8" wide material: 180 P.S.I.
2.22 SUBSECTION 2C - MECHANICAL CONTROLS HEAD UP AND HEAD DOWN LIMIT SETTING Head Up Limit: In order to maximize production in the automatic cycle the HEAD UP LIMIT should be set to match the height of the material. By adjusting the HEAD UP LIMIT SETTING KNOB the head can be set to rise just above the material eliminating unnecessary head travel in the cycle and therefore shortening the cycle time.
2.23 GUIDE ARM POSITIONING It is desirable, in order to maintain maximum beam strength in the blade, to keep the guides as close together as possible. This span is obviously determined by stock size. As shown in Fig. 2C-3 ,in order to increase or decrease the span between the guide arms, simply undo the guide arm lock handle A...
2.24 BLADE CHANGING Select manual mode and raise the head slightly (about two inches at the drive side guide arm). Open the idler and drive doors. Remove the blade guard Fig. 2C-5. Release the carbide guides Fig. 2C-6. Release the blade tension by positioning the blade tension selector switch to '-' Fig. 2C-7. TURN THE HYDRAULICS OFF.
SECTION 3 - MAINTENANCE AND TROUBLESHOOTING BLADE BRUSH NOTE: Proper adjustment and operation of the blade brush is essential to the correct operation of the bandsaw and the longegivity of the blade. Therefore periodic maintenance and inspection of the machine should not be neglected.

SECTION 5 - HYDRAULIC SYSTEM The S-25A hydraulic system does not require any special work on a new machine before its start-up. The hydraulic tank is filled with Valvoline 150-46 hydraulic oil and all machine functions have been tested at the factory to ensure proper operation upon initial start-up.
