Wet Configuration:
•Fill the water reservoir pan [Pan Weldment (A)] with water to within 1 inch (25 mm) of the top. Be sure that the water pump intake Strainer (S) (Figure 6 - Gasoline Model) or Electric Water Pump Intake (U) (Figure 5 - Electric Model) is fully immersed in water at all times. Keep the intake screen of these items clean and free of sludge, slurry, or other foreign material.
Dry Configuration:
•All Models:
WARNING: Conventional “Wet” diamond blades MUST be used with water. DO NOT use conventional “Wet” diamond blades without water. Using con- ventional “wet” diamond blades without water can result in injury or death of the operator or persons in the work area!
WARNING: When cutting without water use only diamond blades that are intended to be used dry (without water). Conventional “Wet” diamond blades MUST be used with water.
⇒Hint: To reduce vibration of the saw, the water reservoir pan [Pan Weldment (A)] can be filled with sand. Be sure to remove the Water Pump (U) (Electric Models) or the water pump intake Strainer (S) (Gasoline Model) to avoid contaminating it with dirt or sand.
WARNING: Always use respiratory protection when dry sawing.
Electric Model (Figure 5):
Before cutting dry unplug the Water Pump (U) from the electric motor by disconnecting the Electrical Cord (NN).
Gasoline Model (Figure 8):
Remove the water pump drive
1.Remove the two shields covering the Water Pump belt drive, and the belt guard (Not Shown).
2.Loosen the two (2) bolts that hold the Water Pump in position. Loosen the drawbolt that tensions the water pump belt.
3.Slide the water pump forward and remove the belt from the water pump pulley.
4.Disassemble the water pump
a.Turn the belt inside out and with one hand squeeze the two strands of the belt together.
b.Twist one tab 90 degrees so that it is parallel with the slot in the adjacent link.
c.Pull the end of that link over the tab.
d.Pull belt end through the other two links.

CAUTION: DO NOT run the Water Pump (U) for extended periods of time without water! The Water Pump could be damaged!
CUTTING OPERATIONS:
•Place material on Conveyor Cart (C) and move conveyor cart to the front of the saw so that the blade DOES NOT contact the material.
•Cutting Methods: This unit allows three methods for the blade to contact the material:
1.Fixed Head: Position the head to the desired height, then tighten the Lock Handle (P) (Figures 5 & 6). Then the material can be pushed into the blade.
2.Hold the Hand Grip (UU) and lower the blade into the material (See Fig. 10). The blade will return to the upper position when force is released.
3.Push the optional Foot Pedal Kit (F) (Fig. 1) with your foot to lower the blade into the material. The blade will return to the upper position when force is released.
Start / Stop (Electric Models): (Figures 9 & 10)
•Open the Water Valve (T) fully, and check the water flow before cutting.
•Start the electric motor by turning the Power Switch (RR) to the "ON" position.
•Cut the material using one of the Cutting Methods de- scribed in the above section.
WARNING: Keep hands clear of rotating blade during operation. READ ALL SAFETY WARNINGS before operating this machine.
CAUTION: DO NOT cut into the cast aluminum area of the Conveyor Cart (C). The blade should only cut into the wooden insert area of Conveyor Cart (C)!
STOPPING THE UNIT (Electric Models):
Stop the unit by turning the Power Switch (RR) to the OFF position. (Fig. 9) Wait for all blade movement to stop before removing material from the machine.
Start / Stop (Gasoline Models): (See Figures 1 & 7)
•Open the Water Valve (T) (Fig. 7) and prime the Water Pump (U) using the Primer Bulb (V) (Fig. 1). Squeeze the Primer Bulb until water passes through the blade guard water tubes.
•Start the engine by using the procedure in the engine operation manual.
•Open the engine throttle full open. All sawing is done at full throttle. DO NOT change the engine governor setting — it is factory set for the correct speed. See the “Specifications” section of this document for proper engine & blade shaft RPM.
WARNING: Keep hands clear of rotating blade during operation. READ ALL SAFETY WARNINGS before operating this machine.
•Adjust the water flow with the Water Valve (T), and check the water flow before cutting.
•Cut the material using one of the Cutting Methods described in the above section.
