Coolant Flow

CAUTION:

  THE COOLANT PUMP MUST BE SUB-

MERGED BEFORE OPERATING TO PREVENT DAM-
AGE 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 blade movement.

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). Eleven quarts of coolant are 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 depen-

dent upon the condition of the saw blade.  If the perfor-
mance 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 cut-

ting accuracy and quality, refer to the Troubleshooting
section (or the blade manufacturer’s guide) for condi-
tions 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 tracking,
refer to the following procedures.

Blade Tracking Adjustment

Blade tracking has been tested at the factory.  Ad-

justment is rarely required when the blade is used prop-
erly or if the blade is correctly welded.  (See figure 10
for location of blade tracking adjustment screws.)

Figure 10: Blade tracking and tensioning

Factory or Field Procedure

1.  Raise the saw head enough to allow the saw motor

to operate.

2.  Loosen four knobs securing the blade cover.  Lift

the cover and swing it backward.

3.  Remove the blade guard mounted on the left blade

guide support.

4.  Remove both blade guide bearing brackets.

NOTE:

  Maintain proper tension at all times using the

blade tensioning mechanism.

5.  Loosen the center locking screws in all three hex

adjustment screws on the blade tensioning mecha-
nism (see figure 10).

CAUTION:  

WHILE PERFORMING THE FOLLOWING,

KEEP THE BLADE FROM RUBBING EXCESSIVELY
ON THE SHOULDER OF THE WHEEL.  EXCESSIVE
RUBBING WILL DAMAGE THE WHEEL AND/OR THE
BLADE.

6.  Start the saw.  Slowly turn the single hex adjustment

screw at the rear of the tracking mechanism to tilt
the idler wheel.  Do not turn either of the other two
adjustment screws.  Turn the adjustment screw until
the blade is touching the shoulder of the idler wheel.

NOTE: 

Turning the screw inward causes the blade to

move toward the shoulder of the wheel.  Turning the
screw outward causes the blade to move away from
the shoulder.

7.  Turn the single hex adjustment screw so the blade

starts to move away from the shoulder of the wheel
— then turn the single hex adjustment screw in the
other direction so the blade stops, then moves slowly
toward the shoulder.

WARNING:  

KEEP FINGERS CLEAR OF THE BLADE

AND WHEEL TO AVOID INJURY.

8.  Turn the single hex adjustment screw to stop the

motion of the blade on the wheel as it gets closer to
