to increase the blade’s lowering speed and clockwise to
decrease the blade’s lowering speed. Note: The valve
does not adjust the blade’s raising speed.

Water Supply
The water supply cools the gearbox, blade and
minimizes dust when cutting. Note: Always test the water
supply for adequate pressure and flow prior to cutting.
Using the Water Supply
1. Connect the water source hose to the water valve
fitting on the left side of the saw.
2. Connect one end of the water supply hose (60”) to
fitting on the right side of the saw (fig. 13).
Figure 13: Water Supply Hose
3. Connect the other end of the water supply hose
(60”) to right side of water solenoid valve located
above the upper gearbox.
4. Connect the short water supply hose (32”) from the
left side of the water solenoid valve to hose fitting at
bottom left side of the upper gearbox.
5. Connect water supply hose (54”) from the hose
fitting at bottom right side of the upper gearbox to
the manifold on the blade guard.
6. Move the water valve lever on right side of saw to
full open. Increase or decrease water flow by
moving the valve lever on the left side of the saw
connected to the source hose. Note: water on/off
operation and flow adjustment can be made from
either side of saw, if desired.
7. When finished cutting, shut off water supply to the
blade guard, shut off water supply at source and
remove source hose from the saw.
8. Drain water from upper gearbox heat sink. (ref.
maintenance instructions: upper gearbox)
Cutting Guides
Use the cutting guides as needed to help follow the
cutting line. Always check the cutting guides for proper
alignment with the blade prior to cutting.
Adjusting the Front Pointer
1. Remove the lanyard from the cable cleat.
2. Lower the front pointer frame to the ground.
3. Loosen both front pointer frame screws.
4. Divide an 8–10 ft piece of string in half.
5. Place the looped end of string into a gullet on the
backside of the blade.
6. Place one string line up against the backside of the
blade and one string line up against the front side of
the blade. Holding the string ends in one hand,
tension the lines out toward the front pointer rod.
Figure 14: Tensioned String Line
7. Adjust the pointer rod to place the tip between the
tensioned string lines.
8. Retighten both front pointer frame screws.
9. Lift the frame off the ground when finished.
10. Tension the lanyard and secure it to the cable cleat.
