material placed on the Cart Assembly (C). If the saw or Head Platform Assembly (B) is dropped or damaged the blade could become mis-aligned so that it no longer cuts “squarely” through the material. If this occurs the blade shaft should be re-aligned so that the saw will produce “square” cuts. If the Blade is severely out of alignment [1/16" (1.5 mm) or more] the Head Platform Assembly (B) may need to be “bent” so that the blade is closer to being aligned. In cases of severe damage the Head Platform Weldment should be replaced. Precise. alignment can be achieved by using Shims (HH) of. various thickness. See the parts list section of this. document for the part number and thickness. information about the shims.

⇒Note: Before starting to align the head platform make sure the blade is flat and is NOT bent or damaged!

⇒Note: When aligning the blade against the square be sure to allow for the difference in thickness between the diamond segment and the center core of the blade!

1.Make sure the Conveyor Cart (C) rolls freely along the pan. If the pan is damaged it must be repaired or. replaced before the blade can be aligned. Lock the Head Platform Assembly (B) securely in a horizontal. position.

2.PARALLEL ALIGNMENT (Figure 11): Supply a Square (GG) and place it on the Conveyor Cart (C) and roll the cart while the Square (GG) rests against the blade. Ad- just the Blade Shaft into Parallel Alignment (if required) by putting Shims (HH) between the blade shaft housing and the head platform weldment at location “A1” (Figure 11). Loosen, but do not remove, the Capscrews (JJ) holding the blade shaft in position. Slide a shim, of the proper thickness, upward and position around the thread of one of the capscrews. Tighten the hardware and check the blade alignment. Add more shims if required until the blade shaft has Parallel Alignment.

3.PERPENDICULAR ALIGNMENT (Figure 12): Place the Square (GG) on the Conveyor Cart (C) so that it is against the saw blade and is below the center of the blade shaft. If the Square (GG) does NOT contact the Diamond Blade (DD) along the entire height of the square, the blade shaft must adjusted into Perpendicular Alignment. Adjust the blade shaft by putting Shims (HH) between the blade shaft housing and the head platform weldment at location “B2” (Figure 12). Loosen, but do not remove, the Capscrews (KK) that hold the blade shaft in position. Slide a shim, of the proper thickness, inward and position around the thread of one of the capscrews. Tighten the hardware and check the blade alignment. Add more shims if required until the blade shaft has Perpendicular Alignment.

8 V-Belt Tension

All Models (FIGS. 5 & 6):

•Check V-Belt tension when unit is new and never set belt tension beyond this point.

•The saw is equipped with high tension V-Belts. The belts are properly tensioned at the factory, but after a few hours of operation they will stretch and become loose.

•Tensioning Blade Shaft V-Belts:

1.Loosen the four (4) capscrews that attach the. motor (Electric Models), or the Engine Platform. (Gasoline Models).

2.Tighten the Belt Tensioning Bolt (SS) at the rear of the saw until the belt a tightened to the original. factory tension.

3.Re-tighten the four (4) capscrews that attach the. motor (Electric Models), or the Engine Platform (Gasoline Models).

Electric Model:

•See “All Models” from above text.

Gasoline Model:

•Blade Shaft V-Belt Tension (FIG. 6): Excessive belt. tension will cause engine misalignment because the. engine is mounted on four (4) rubber vibration Isolators

(W). Stop tensioning the blade shaft drive V-belt when the center section of the front right hand Isolator (W) begins to separate from its mounting plate. Tensioning the Blade Shaft drive V-Belt beyond this point is not. recommended because the front right hand Isolator (W) will not function properly.

•Water Pump V-Belt (EE) Tension (FIG. 8): May need to be tightened after a few hours of operation. Over time this V-Belt may stretch beyond the length of the. adjustment slot. If this happens simply remove the. V-Belt and take out one or more links (as required) from its length.

9 Important Advice

•Never transport the saw with the cutting head positioned on the frame. The movement can knock the head out of alignment.

•When storing for an extended period of time, use a wire brush to remove hard, caked sludge. Clean and. thoroughly lubricate moving parts - so on the next job the saw is ready for operation.

•Drive belts must be tight. When the belts are loose, power is lost. Replace worn belts without delay!

•The blade must fit the arbor snugly - especially diamond blades. Otherwise, pounding will occur and this will. seriously damage the blades. If the arbor shoulder is grooved where the diamond blade has bound in the cut as the shaft has continued to turn, the arbor must be replaced, or the blade life will be severely shortened.
