FS2 CONCRETE SAW — OPERATION
Saw Alignment
1. The FS2 employs a front and rear pointer (Figure 22) that has
been precisely aligned with the diamond blade at the factory.
Referencing the figure below, accurate tracking is accom-
plished by referencing the front and rear pointer tips over the
cut line. Precise saw direction is accomplished by slight
operator pressure against the handle bars.
Figure 22. Saw Pointers (Front/Rear)
2. To reorient a pointer position, loosen the hex screw that
secures the pointer bar to the shaft, adjust as necessary, and
retighten the hex screw.
3. For operator comfort, an ergonomically designed handle bar
adjusts by loosening two clamping knobs (page 46, item 8),
and adjusts to the desired height. Tighten the knobs back
down when the desired height is met.
5. Set the depth and saw only as the job conditions and
specifications require. Unnecessary deep sawing is wasteful
to the life of your blade.
6. 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.
CAUTION: CAUTION: CAUTION: CAUTION: CAUTION:
ALWAYS saw in a straight line only. Serious
damage to the blade may occur if the saw is
twisted or forced to cut radius shapes.
7. The rotation of the blade creates a tendency for the saw to pull
in a particular direction (to the right if the blade is mounted on
the right, to the left if the blade is mounted on the left).
8. To ensure a straight line of sawing, apply pressure to the
appropriate handle as you slowly advance the saw forward.
DO NOT force the blade to the cut any faster than its natural
tendency.
WARNING
If the engine stalls for any reason during
sawing, raise the blade out of the cut
before restarting.
9. 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.
10. Factors for sawing economy:
l
Type of Blade
l
Depth of Cut
l
Sawing Speed
l
Characteristics of the Material Being Cut
WARNING
The operator must wear the appropriate protective equipment
and clothing while engaged in sawing.
1. Connect hose from water source to the hose fitting connec-
tion (see item 14, page 44 "Water System Assembly") on the
saw. The source pressure should be approximately 40 psi.
2. Select the “flood” position on the console (Figure 6), and
ensure the proper flow and rate 4-5 gallons/ minute (15-19
Lt/min) is equally directed to both side of the blade.
3. Advance engine throttle to full (FAST) position.
4. Slowly lower the blade onto your cut line by cranking the
Raise/Lower handle clockwise: while observing the depth of
the cut desired by referencing the depth feed gauge (Figure
6).
IF the water supply to your blade is interrupted, stop
sawing immediately.
