However, any machine used improperly can be rendered inefficient and unsafe. It is absolutely mandatory that those who use our products be properly trained in how to use them correctly. They should read and understand the Operators and Parts Manual as well as all labels affixed to the machine. Failure in following all of these warnings can cause serious injuries.

Machinery general safety warnings

1. Always wear protective eye wear when operating machinery. Eye wear shall be impact resistant, protective safety glasses with side shields which comply with ANSI Z87.1 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection.

2. Wear proper apparel. No loose clothing or jewelry which can get caught in moving parts. Rubber soled footwear is recommended for best footing.

3. Do not overreach. Failure to maintain proper working position can cause you to fall into the machine or cause your clothing to get caught — pulling you into the machine.

4. Keep guards in place and in proper working order. Do not operate the machine with guards removed.

5. Avoid dangerous working environments. Do not use stationary machine tools in wet or damp locations. Keep work areas clean and well lit. Special electrics should be used when working on flammable materials.

6. Avoid accidental starts by being sure the start switch is OFF” before plugging in the machine.

7. Never leave the machine running while unattended. Machine shall be shut off whenever it is not in operation.

8. Disconnect electrical power before servicing. Whenever changing accessories or general maintenance is done on the machine, electrical power to the machine must be disconnected before work is done.

9. Maintain all machine tools with care. Follow all maintenance instructions for lubricating and the changing of accessories. No attempt shall be made to modify or have makeshift repairs done to the machine. This not only voids the warranty but also renders the machine unsafe.

11. Secure work. Use clamps or a vise to hold work, when practical. It is safer than using your hands and it frees both hands to operate the machine.

12. Never brush away chips while the machine is in operation.

13. Keep work area clean. Cluttered areas invite accidents.

14. Remove adjusting keys and wrenches before turning machine on.

15. Use the right tool. Don't force a tool or attachment to do a job it was not designed for.

Operating Instructions

Using the vise

The vise on the saw table has two jaws. The jaw closest to the right hand side of the table is the stationary jaw. This jaw is firmly secured to the table using its pivot and lock bolts. When making a straight cut the stationary jaw is at right angles to the saw blade. When making an angle cut, the stationary jaw is first loosened, then adjusted to the desired angle, then secured to the table, again.

The jaw closest to the left hand side of the table is the locking jaw. This jaw clamps the workpiece against the stationary jaw to hold it securely for cutting. The locking jaw can pivot to conform to the angle of the work piece which is held in the stationary jaw.

Before cutting can begin, the vise must be properly set and positioned. The procedures are different for right angle cutting and for angle cutting. Setting procedures are given in the following sections.

Figure 1: Vise jaw nomenclature

Locking vise jaw

The locking jaw is an assembly which includes the lead screw nut which encases the lead screw, the lead screw shaft (which screws into the lead screw nut,) the thrust shaft, spring, and quick release handle.

The thrust shaft moves up or down when the quick release handle moves up or down.

The thrust shaft has a nut under the quick release handle which adjusts the clamping pressure between the adjustable jaw and the table, itself. When this nut is too tight, the adjustable jaw cannot pivot. When this nut is too loose, the jaw can pivot, and also tilt upward. Therefore, this nut should be slightly loose. This will allow the jaw to pivot an conform to any angle at which the stationary jaw is set.

However, you should guard against excessive loosening of this nut. If too loose, the jaw can tilt when it contacts the workpiece and full clamping pressure cannot be effectively applied to the workpiece.

If the shaft is too tight to allow pivoting of the jaw, loosen the shaft slightly by turning the nut under the quick release handle counterclockwise. If the jaw tilts exces-

sively, use the nut under the quick release handle to tighten the shaft slightly so the jaw slides easily, but flat against the saw table.

The locking vise jaw is tightened or loosened against the workpiece being cut by using the lead screw handle. The handle is attached to a lead screw underneath the saw table. The lead screw has a series of grooves on its length. These grooves capture a thrust shaft on the lower side of the locking jaw. As the lead screw handle is turned, the grooves move to the left or right, and therefore the locking jaw is moved to the left or right to open or close the jaw against any workpiece on the table.

The thrust shaft on the locking vise jaw is a component part of the quick release handle on top of the locking jaw. This quick release handle is spring loaded to force the handle (and, therefore, the thrust shaft) downward.

When you pull up on the quick release handle, the thrust shaft is removed from its groove. This allows you to slide the jaw to a new position on the table. Releasing the handle pushes the thrust shaft against the lead screw shaft. When the lead screw handle is turned, a groove will

eventually catch the thrust shaft and allow you to open or close the locking jaw at its new lead screw position.

When you slide the jaw to a new position, you can see where the nearest lead screw groove is by looking through the slot above the lead screw. (See Figure 1.)

Changing the locking jaw location:

1. Lift the quick release handle.

2. Slide the jaw until it contacts the workpiece.

3. Turn the lead screw handle until the thrust shaft drops into a groove.

4. Further turning of the lead screw handle will either clamp or release the workpiece in the vise. Turn clockwise to increase clamping pressure. Turn counterclockwise to release clamping pressure.

Stationary vise jaw

The stationary vise jaw pivots on the pivot bolt, Figure 1, and is locked at any required angle by the lock bolt.

There are two different table positions for the stationary vise jaw. One position is used for right angle cuts ("straight" cutting) and the other position is used for cutting of all other angles. Moving the vise from one position to the other requires unbolting and re-bolting the jaw to the saw table.

Four tapped holes in the saw table allow a change of pivot and lock bolt position. The holes in the right-most position closest to the motor are used for right angle cutting. The holes in the left-most position are used for all angle cutting.

Adjusting stationary jaw: straight cuts

For accurate right angle or "straight" cutting, adjust

the vise as follows:

1. Disconnect the saw from its electrical power source to prevent accidental start-ups.

2. With the saw arm and blade in horizontal position, place a machinist's square against the blade and stationary vise jaw. (See Figure 2.)

3. If the vise jaw is not square to the blade, loosen both the pivot and lock bolts shown in Figure 1, and adjust the jaw until it is square.

4. Tighten the pivot and lock bolts.

5. Reconnect electrical power to the saw.

Figure 2: Setting the stationary jaw at right angles to the saw blade.

Adjusting stationary jaw: angle cuts

The angle of the stationary vise jaw with respect to

Changing the stationary vise jaw position:

1. Remove the pivot and lock bolts.

2. Slide the stationary jaw to the required position on the table.

3. Re-insert the pivot and lock bolts.

4. Adjust stationary jaw angle according to requirements for straight or angle cuts, then tighten both bolts securely.

the saw blade is what determines the cut angle on the workpiece. The stationary jaw can be adjusted to any angle between 0 degrees (right angle to the blade) and 45 degrees.

In order to cut angles, however, it will be necessary for you to move the stationary vise jaw to its left-most set of attachment holes as described in the following sections.

After placing the jaw in the angle cutting position, you can adjust to the desired cutting angle using one of the two following methods.

Adjusting angles with the scale on the saw table

There is a scale on the rear of the saw base which

can be used to establish the angle of cut.

1. Raise the saw arm to full height and lock it in position with the quick shut-off valve.

2. Slide the locking jaw to full open position.

3. Loosen the pivot and lock bolts shown in Figure 1.

4. Lay a straight edge on the saw frame so it contacts the stationary vise jaw. (See Figure 3.)

5. Turn the vise jaw until the straight edge is above the angle of cut you require as shown on the angle gauge.

6. Tighten both the pivot and lock bolts.

7. Remove the straight edge and proceed to cut as described in Angle sawing.

Figure 4: Using a protractor to set jaw angle

Figure 3: Using table scale to set jaw for angle cuts

Adjusting stationary jaw for high accuracy angle cutting:

1. Raise the saw arm to full height and lock it in position with the shut-off valve.

2. Open the vise to full width.

3. Loosen the pivot and lock bolts shown in Figure 1.

4. Open the shut-off valve and lower the saw arm until it is at full horizontal position.

5. Take a machinist's protractor and set it to the angle you need to cut.

6. Lay the protractor on the saw table and place one edge of the protractor against the saw blade and the other edge against the stationary vise jaw. (Figure 4.)

7. Adjust the stationary vise jaw until its angle is correct with respect to the blade, then lock the stationary jaw firmly using the pivot and lock bolts.

The saw is now accurately set to the exact angle you have set on the machinist's protractor. You can now saw the workpieces according to instructions on Angle sawing.

Setting the blade guides

To produce accurate cuts the distance between the blade guide/supports must be set correctly. Whenever possible, set the blade guide assembly so it clears the workpiece by approximately 1/8 inch on either side of the workpiece.

The guides may be moved by loosening the lock handles which secure the bracket bars to the saw arm.

There is, however, a limit to how close the guide can be set with respect to the table. When set too close to the blade clearance slot, the guide bearings can hit the table casting and prevent the arm from moving to full horizontal. When this happens, the saw cannot complete its cut.

This won't be a problem with the right-hand guide. On the other hand, the left-hand guide typically cannot be much closer to the right-hand guide than 6 inches or so. Therefore, when cutting smaller section material, be sure the blade is correctly adjusted, tensioned properly, sharp, and appropriate to the type of material being cut.

Controlling the cut:

Using the stock stop

Hydraulic feed control

The weight of the saw arm typically provides all of the force needed to move the saw blade through the workpiece. In fact, if the full weight of the arm is allowed to make the cut, rapid blade wear and poor cutting accuracy will result. Therefore, a hydraulic feed control is provided which gives the operator control over the speed and efficiency of cutting.

The hydraulic feed control is a single-acting hydraulic cylinder attached between the saw base and saw arm. The hydraulic control cylinder has two flow controls. The control needle valve -- used by the operator to control the rate of cutting -- is on top of the cylinder. A quick shut-off valve is located in a hydraulic line on the outside of the cylinder.

The control cylinder is single-acting because it can be used to resist motion in the downward direction, only. The control cylinder offers no resistance to upward movement.

The amount of downward force can be controlled by using the needle valve on top of the cylinder. When the needle valve is closed the cylinder is "locked." With the needle valve open slightly, the cylinder permits slow, or light downward force. As the needle valve is opened further, increasing weight of the saw arm presses on the blade and workpiece.

The needle valve is opened, during any cut, until the operator determines that the saw is operating efficiently. This is usually evaluated by observing chip formation. See the section on Blade Selection, for more information on evaluating cutting efficiency.

The quarter-turn quick shut off valve in the external line of the control cylinder can be turned to lock the cylinder at any time. For instance, it can be used to lock the blade above the work piece to allow you to measure the length of cut on the workpiece. Or, it can be used for making repeated cuts after the needle valve has been set for best cutting efficiency. (This is described in the next section.)

To close the hydraulic control circuit and lock the cylinder, turn the quick shut off valve handle so it is at right angles to the hydraulic line or hydraulic cylinder.

To open the hydraulic control circuit and return feed control to the needle valve, turn the quick shut off handle so it is parallel with the hydraulic line or hydraulic cylinder.

for repeated cuts

If you are cutting multiple pieces of stock, all to the

same specified length, use the stock stop.

1. Lower the saw arm to its horizontal position.

2. Loosen the stock stop set screws as necessary to slide the stop upward and more-or-less into position. (There are two set screws which are use to lock the stop stock in position. One is on the saw table and is typically used to adjust the distance between the stop and the blade. The other set screw is on the stop, itself, and is typically used to adjust the height of the stop above the table. However, you can use any combination of set screws you find convenient to adjust the stop to the distance and height which works for the stock you are cutting.)

3. Using a ruler or scale, measure the distance between the blade and stock stop.

4. When the correct cut-off distance is obtained, be sure the stock stop is at a position which allows the cutoff piece to fall away from the blade as the cut is completed. Then, tighten the stock stop set screws securely.

5. Raise the saw arm.

6. Place a workpiece in the saw vise and slide the workpiece so it contacts the stock stop.

7. Open the hydraulic control cylinder quick shut off valve and move the saw blade to just above the workpiece then close the needle valve so the arm is locked in position.

8. Measure the distance between the end of the workpiece and the blade to verify that you have set the stock stop at the correct distance. (See Figure 6.)

9. When you are satisfied that your cut-off distance is correct, you may begin cutting by turning on the saw and opening the needle valve until the blade is cutting efficiently.

To continue making multiple cuts take the following steps:

1. Do not change the setting on the needle valve.

2. Raise the saw arm so it clears the stock being cut and lock the hydraulic control cylinder using the quick shut off valve.

3. Release the vise slightly using the handle wheel -move the stock up to the stock stop -- tighten the vise again.

4. Turn on the saw and open the quick shut off valve. Because you established an efficient cutting rate on the previous cuts using the needle valve, there is no reason to change its setting. The quick shut off, alone, can be used to begin and complete the cut.
