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. The preferred method of sawing is to step cut in increments
of 2” (51 mm). “ 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/side-ward pressure may
damage the blade.
Finishing a Cut
1. Raise the blade out of the cut by utilizing the ball handle
adjustment assembly. Raise the blade high enough out of
the cut to clear the surface and allow the saw to be maneu-
vered.
2. Move the engine throttle lever to the idle (SLOW) position
(Figure 20).
3. Set the engine ON/OFF switch to the “OFF” position
(Figure 18).
4. Place the two-way water valve (Figure 6) in the “OFF”
position .
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:
z
Determining WET or DRY cutting
z
Material to be Cut
z
Type of Saw Being Used
z
Horsepower of Saw
z
Hardness Characteristics of the Material
z
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.
z
FS 1 14” Capacity-3,200 RPM.
z
FS 1 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.
