rod. Position the stop post against the work piece and tighten the knob in the stop L-bracket. The stop post can be moved left or right as required to place the stop post against the work piece.

Starting the Saw

WARNING: NEVER OPERATE THE SAW WITH- OUT BLADE COVERS IN PLACE AND SECURED.

CAUTION: MAKE SURE THE BLADE IS NOT IN CONTACT WITH THE WORKPIECE WHEN THE MOTOR IS STARTED. DO NOT DROP THE SAW HEAD ON THE WORKPIECE OR FORCE THE SAW BLADE THROUGH THE WORKPIECE.

1.Raise the saw head.

2.Clamp the workpiece in the vise. (See figure 9 for examples of workpieces in the vise.)

3.Be sure to start the saw blade drive motor before allowing the blade to contact the workpiece.

4.Start the motor and allow the saw to come up to speed.

5.Slowly bring the saw down onto the workpiece. Adjust feed rate using feed rate control.

6.DO NOT LOWER THE SAW HEAD AT A RATE FASTER THAN THE SAW’S CAPABILITY OR FORCE THE CUT. Adjust the feed rate so the hydraulic cylinder provides the proper amount of downward force.

7.The saw will automatically shut off at the end of the cut.

Coolant Flow

CAUTION: THE COOLANT PUMP MUST BE SUB- MERGED BEFORE OPERATING TO PREVENT DAMAGE TO THE PUMP.

1.The blade guides are fitted with coolant fittings. Coolant is provided to the fittings through intercon- necting tubing. The coolant is dispensed directly onto the saw blade.

2.Adjust the coolant flow valves on the top, rear of the saw head as required to provide the desired flow. The flow should be no more than the blade can draw into the workpiece by movement of the blade.

3.The coolant flow can be stopped in two ways:

1)By using the coolant pump switch on the electrical equipment box, or

2)By closing the coolant flow valves on the top,

rear of the saw head.

Coolant Mixture and Quantity

The general purpose coolant is a mixture of water soluble oil and water. Mix one part of soluble oil (TRIM SOL) to ten parts of water (one quart oil, ten quarts of water). The eleven quarts of coolant is the amount required for the coolant pump to operate properly.

There are numerous coolants on the market that are formulated for special applications. Consult your local distributor for details in the event you have a long range production task, or are required to cut some of the more exotic materials.

Adjustments

The efficient operation of the cut-off saw is dependent upon the condition of the saw blade. If the performance of the saw begins to deteriorate, the first item that you should check is the blade.

If a new blade does not restore the machine’s cutting accuracy and quality, refer to the Trouble- shooting section (or the blade manufacturer’s guide) for conditions to consider and adjustments that can be made to increase the life of the blade.

To change the blade, refer to Changing Blades in the Maintenance section. To adjust the blade track- ing, refer to the following procedures.

Blade Tracking Adjustment

Blade tracking has been tested at the factory. Adjust- ment is rarely required when the blade is used properly or if the blade is correctly welded. (See figure 10 for location of blade tracking adjustment
