FS2/FS2SP Concrete SAW Operation, Blade Speed

FS2/FS2SP CONCRETE SAW — OPERATION

6.Align the saw along the cut line utilizing the front and rear pointers.

7.Slowlylowerthediamondbladeontothecutlineby cranking theRaise/Lowerhandleclockwise. Whentheblade“touches” the cutting surface, “zero-out” the depth feed gauge (Figure 5, item 12) by rolling the depth until “0” is lined up with the slip mark. Slowlycontinuetolowerthebladeintothecutuntilthe desired depth is achieved.

8.Set the sawing depth and saw only as job conditions and specifications require. Deep sawing is wasteful to the life of the blade and can negate the effectiveness of the water misting system to suppress dust. The preferred method of sawing is to “step cut” in increments of 2” (51 mm). Step cutting provides the optimum opportunity for the blade to cut fast and last it’s longest.

9.The rotation of the blade creates a tendency for the saw to slightly pull in a particular direction. To ensure a straight line of sawing, apply pressure against the appropriate handle bar as you slowly advance the saw forward. DO NOT force the blade into the cut any faster than its designed tendency is effective cut and remove the material.

WARNING

If the engine stalls for any reason during sawing, raise the blade out of the cut before restarting.

10.The operator must recognize and adhere to the optimum speed that the saw advances while sawing. DO NOT force the saw in the cut. Observe the engine tachometer from time to time to get the feel for a smooth sawing pace relative to RPM.

11.Factors for sawing economy:

3.Push the console engine ON/OFF button to the “OFF” position (Figure 5, item 1).

4.Set the engine ON/OFF switch to the “OFF” position (Figure 6, item 3).

5.Place the water valve (Figure 5, item 3) in the “OFF” position (as required).

WARNING

Engine components can generate extreme heat.

Diamond Blades and Blade Speed

1.Diamond sawing consist of cutting WET (using water to cool the blade) or DRY (using the circulating air to cool the blade).

2.Selecting the diamond blade type and grade defines how the blade will perform both in cutting speed and blade life.

3.Selection of the proper diamond blade consists of:

zDetermining WET or DRY cutting

zMaterial to be Cut

zType of Saw Being Used

zHorsepower of Saw

zHardness Characteristics of the Material

zPerformance Expectations

Blade Speed

1.A diamond blade’s performance is directly connected to specific peripheral (rim) speeds.

2.The following shaft rotational speeds have been factory set to ensure optimum blade performance.

zType of Blade

zDepth of Cut

zSawing Speed

zCharacteristics of the Material Being Cut

zWet or Dry Sawing

Finishing A Cut

1.Raise the blade out of the cut by cranking the Raise/Lower handle counter-clockwise (Figure 5, item 10). Raise the

blade high enough out of the cut to clear the surface and allow the saw to be maneuvered.

2.Move the engine throttle lever to the idle (SLOW) position (Figure 20).

z	FS2/FS2SP	20” Capacity-2,600 RPM.

WARNING

Operating saw blades at rotational speeds greater than those specified by the manufac- ture can cause blade damage, and may in- jure the user or others in the operating area.
