4. Use "step" cutting as explained previously when using abrasive blades.
5. Use "jam" or "step" cutting when using dry cutting diamond blades.
E. How To Use Saw For Wet Cutting
Water may be supplied either by filling the water pan to within a half-inch of the top
(for continuous use of the same water) or by placing a barrel of water next to the
saw (for continuous flow of clean water). When using water from a barrel, remove
water from pan and submerge it in water barrel. Remove the drain plug so the
used water and sludge will drain from pan.
1. Prepare water supply.
2. Install water curtain on cutting head pivot bar.
3. The saw uses a belt driven mechanical pump which only operates when the
engine/motor is running.
4. Handle on petcock should be turned in line with the water flow. Start motor and
be certain that both sides of the blade are getting water.
5. Be sure that the water covers the bottom of the pump at all times. Do not let
sludge and dirt get deep enough in the pan to block the pump inlet.
6. Use "step" cutting with abrasive blades as previously directed.
7. Use "jam" cutting or "step" cutting with diamond blades as previously
described.
III. MAINTENANCE
The saw requires very little maintenance for long satisfactory operation. However,
the following points must be watched:
A. V-Belts
The drive belts are made of premium oil and heat resistant materials. They require
very little adjustment, but should be tightened after the first few days of running.
Adjustment and Alignment
Warning: Never make adjustments to v-belts and pulleys while engine is running.
1. The best tension for a v-belt drive is the lowest tension at which the belts will
not slip under full load.
2. Simply take up the drive until the belts are snug in the grooves. Run the drive
for about 15 minutes to "seat" the belts. Then impose the peak load. If the belts
slip, tighten them until they no longer slip at peak load.
3. Remember, too much tension shortens belt and bearing life.
