03900A REVERSING RAIL SAW
REPAIR TROUBLESHOOTING:
1. SAW DOESN’T CUT RAIL FAST ENOUGH:
•
CHECK FLOW UNDER LOAD. POWER SOURCE MUST MAINTAIN 10 GPM UNDER NORMAL
LOAD. INSTALL FLOW METER AND RESTRICT TO APPROXIMATELY 1500 PSI. FLOW SHOULD BE
10 GPM AT 1500 PSI WORKING PRESSURE.
•
DETERMINE THAT OPERATOR IS USING SAW PROPERLY. THE SAW SHOULD BE OSCIL-
LATED BACK AND FORTH WHILE CUTTING. THE AVERAGE CUTTING TIME IS 1 - 2 MINUTES FOR
132 LB RAIL.
•
THE PROPER RPM OF THE MATWELD SAW IS 3200 ( + 100) RPM AT 10 GPM.
•
THE SAW RPM IS PROPORTIONAL TO THE FLOW PROVIDED. IF THE FLOW DROPS TO 8
GPM THE RPM OF THE SAW WILL BE 2400 RPM, MUCH TOO SLOW FOR CUTTING RAIL. IF THE
FLOW IS INCREASED TO 18 GPM THE SAW RPM WILL BE 5500 RPM. PROPER FLOW IS CRITI-
CAL FOR PROPER OPERATION AND SAFETY OF THE OPERATOR. DETERMINE IF THE POWER
SOURCE IS DELIVERING THE PROPER FLOW AND RELIEF PRESSURE TO THE SAW AND ALL
OTHER SPEED RELATED TOOLS BY CHECKING FLOW WITH A FLOW GAUGE. (MATWELD PART
NUMBER 03600 – FLOW AND PRESSURE GAUGE, OR EQUIVALENT).
2.
THE SAW CUTS CROOKED:
•
PLAY IN ANY OF THE CONNECTIONS ON CLAMP ARM.
•
BAD, GLAZED, OR DEFECTIVE BLADES.
•
LOW FLOW REDUCING SAW RPM.
•
LOOSE ARBOR ON SAW MOTOR.
•
LOOSE BLADE FLANGES.
•
BENT SAW FRAME BETWEEN MOTOR AND PIVOT POINT.
•
