■

■

■

■

SAW TRANSPORTATION SAFETY

■

■

■

■

■

Use appropriate steel centered diamond blades
manufactured for use on concrete saws.

Always inspect diamond blades before each use. The blade
should exhibit no cracks, dings, or flaws in the steel centered
core and/or rim. Center (arbor) hole must be undamaged
and true.

Examine blade flanges for damage, excessive wear and
cleanliness before mounting blade. Blade should fit snugly
on the shaft and against the inside/outside blade flanges.

Ensure the blade is marked with an operating speed greater
than the blade shaft speed of the saw.

Only cut the material that is specified by the diamond blade.
Read the specifications of the diamond blade to ensure the
proper tool has been matched to the material being cut.

Always keep blade guards in place. Exposure of the diamond
blade must not exceed 180 degrees.

Ensure that the diamond blade does not come into contact
with the ground or surface during transportation. DO NOT
drop the diamond blade on ground or surface.

The engine governor is designed to permit maximum engine
speed in a no-load condition. Speeds that exceed this limit
may cause the diamond blade to exceed the maximum safe
allowable speed.

Ensure that the blade is mounted for proper operating
direction.

Use the lifting handle and/or the appropriate lifting equipment
to ensure the safe movement of the saw.

DO NOT use the handle bars and/or front pointer as lifting
points.

NEVER attempt to tow the untrailered saw behind a vehicle.
Do not use on slopes or on extremely unlevel surfaces. An

engine tipped to extreme angles may cause oil to gravitate
into the cylinder head making the engine difficult to start.

NEVER transport the saw with the blade mounted.

Diamond Blades.

The jig-welded reinforced heavy gauge steel frame and chassis
assembly are designed to eliminate operational bending and/or
flex that would lead to diminished blade performance. Also, the
frame's general weight-to-strength ratio and center mounted
blade design ensure accurate tracking in the cut.

A robust blade shaft bearing assembly ensures minimal flutter
and shaft harmonics providing the most advantageous
conditions for a diamond blade at operating speeds.

Heavy-duty front and rear axles, polyurethane wheels with
permanently sealed ball bearings, and solid undercarraige
assembly provide years of reliable use. The SlabSaver
incorporates an innovative PosiLok raise/lower control assembly
that provides fingertip control of blade orientation, infinitely
adjustable locking blade depth control, and depth feed gauge.
Retractable front & rear pointers with "tracking wheels" are
provided to support precise straight sawing. This system permits
the operator to quickly adjust the blade cutting depth and
safeguard against "blade-creep" during sawing operations. For
operator comfort and ease of transportation & storage, an
adjustable locking handle bar is provided.

Operator control of the saws is safely accomplished with
adjustable handle bars, and a conveniently oriented raise/lower
lever and depth adjustment wheel.

FCG1 CONCRETE SAW — BLADES

SAW BLADES

For maximum performance and return on investment use:

Diamond Blades.

Saw blades, or cutting disks are available in either an abrasive
design or as diamond blades. Either blade will work on the
FCG1 Concrete Saw, however, diamond blades are
recommended. Diamond blades are available specifically
designed for cutting green concrete, cured concrete, asphalt, as
well as a "V-Cut" blade use for decorative work. Ask your dealer
about your specific cutting application.

SAW BLADE INSPECTION

2. Edge of the Steel Core - Check the diameter edge for
discoloration (blue oxidation) indicating an overheating
condition caused by insufficient cooling water/air.
Overheating of blades may lead to loss of core tension and/
or increase the possibility for blade failure. Make sure the
steel core's width is uniform about the rim of the blade, and
not succumbing to an "under-cutting" condition brought
about by highly abrasive material or improper under-cutting
core protection.

3. Directional Arrow - Ensure that the blade is oriented
properly on the blade shaft for sawing. Reference the
directional arrow on the blade and place it so the direction
of rotation "downcuts" with the turn of the shaft.

4. Diamond Segment or Rim - Ensure there are no cracks,
dings, or missing portions of the diamond segment/rim. DO
