2. Always break in the blade before you start normal cutting.
3. Do not apply excessive down pressure on the workpiece. Excessive down pressure will cause the teeth
to remove too large of a chip, resulting in premature dulling or breakage.
4. Use a good quality, synthetic coolant and maintain the proper ratio of coolant to water as
recommended in SECTION 4.7.
5. Have your blades re-sharpened by someone who has the right equipment for circular cold saw blades.
Improper re-sharpening is one of the most common problems encountered in cold sawing.
6. Keep the blade flange, the face of the blade spindle and the blade clean and free from nicks. Any
contamination or nicks on the flange, spindle or the blade will cause the blade to run out of alignment.
7. Always remove the back lash when installing a blade. For instructions, REFER TO SECTION 6.1.
Also, check the condition of the drive pins when replacing the blade. If the drive pins are broken or
worn, replace them.
8. Any of the above problems may cause a condition known as pick-up. Pick-up is caused when small
pieces of the material being cut adhere themselves to the blade. When pick-up is present, you will feel
a jerking or jumping motion in the saw head while cutting. This is caused by the blade being pinched
as it goes through the material where the pick-up is present. Pick-up can be removed by using a fine
honing stone or a very fine file. When removing pick-up, care must be taken not to remove any part
of the blade. After the pick-up has been removed, review the above items to determine what caused
the problem.
8.3 COOLANT SYSTEM
1. IF COOLANT WILL NOT FLOW:
A. Check the wiring connections to the pump and make sure that the pump is running.
B. Check the level of the coolant in the reservoir. If the level is less than 3 inches, the fluid will not flow.
C. Check the reservoir for contamination or sludge build-up that may be blocking the pump inlet.
D. Remove the coolant line from the guard and make sure that it’s clear. Also, make sure that the valve
on the guard is open.
2. IF THE COOLANT PUMP IS LEAKING:
A. Check the connections on the coolant lines.
B. If the pump itself is leaking, there is a seal kit available. For instructions, SEE SECTION 5.4. For
part numbers, SEE SECTION 9.6.
