Dry Saw Operation
WARNING
The operator must wear the appropriate protective equipment
and clothing while engaged in sawing.
1. Ensure the proper DRY Cutting blade is selected for the job.
2. With the 14" blade guard, select the “MIST” position (misting
water) or the “OFF” position on the console (Figure 6). If
misting water is desired, the water source must be able to
deliver 40 psi of pressure to ensure an optimum spray
pattern.
3. The Water Misting system is designed to suppress the dust
signature caused by dry sawing. The aerosol spray pattern
and blade guard design greatly diminish the amount of dust
that is created. The misting water also acts as an added
coolant for the blade.
4. The preferred method of sawing is to step cut in increments
of 2” (51mm). “ Step-cutting” provides the optimum opportu-
nity for the blade to cut fast and last its longest. Airflow acts
as a blade coolant during sawing. Cutting too deep with one
pass, or exerting excessive forward/sideward pressure may
damage the blade.
Finishing a Cut
1.
Raise the blade out of the cut by cranking the Raise/Lower
handle counter-clockwise (Figure 6). 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).
3. Push the console engine ON/OFF button to the “OFF”
position (Figure 6).
4. Set the engine ON/OFF switch to the “OFF” position
(Figure 6).
5. Place the three-way water valve (Figure 17) in the “OFF”
position (as required).
WARNING
Engine components can
generate extreme heat.
Diamond Blades and Blade Speed
1.
Diamond Sawing consists of cutting WET or DRY.
2. Matching the correct blade for the specific job and material
being cut optimizes performance and value.
3. Selection of the proper diamond blade consists of:
l
Determining WET or DRY cutting
l
Material to be Cut
l
Type of Saw Being Used
l
Horsepower of Saw
l
Hardness Characteristics of the Material
l
Performance Expectations
4. Selecting the “grade” of diamond blade often defines the
performance factors that can be achieved. Multiquip offers a
variety of diamond blade grades to provide the desired level
of valve and performance.
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.
l
FS2 14” Capacity-3,200 RPM.
l
FS2 18” Capacity-2,700 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.
