FCG1 CONCRETE SAW— GENERAL INFORMATION
Intended Use
Operate the FCG1 Saw , tools and components in accordance
with the manufacturer's instructions. Use of any other tools for
stated operation is considered contrary to designated use. The
risk of such use lies entirely with the user. The manufacturer
cannot be held liable for damages as a result of misuse.
This saw is not intended for wet cutting. (The use of water sprayed
onto the tool [blade] during the cutting operation).
FAMILIARIZATION
This FCG1 Saw is designed for dry sawing of concrete slabs
utilizing diamond blades. The saw has been engineered for
general and industrial flat sawing applications that include: Joint
Sawing of Green Concrete, Decorative Sawing in Cured
Concrete, Light Demolition Sawing and "V" Groove
Beveling. The simple and compact nature of the SlabSaver
makes it a perfect sawing tool for one person to operate and
transport. The saw combines innovative features, top quality
components, and a committed attention to state-of-the-art
manufacturing.
For peak performance, the SlabSaver has been engineered to
operate a powerful 4.8 Kw (6.5 HP) Honda or 5.1 Kw (7 HP)
Robin Gasoline engine and 254 mm (10") diameter diamond
blades. This special design allo ws for fast, clean cuts in diff erent
materials at depths from 6.4 mm to 82.6 mm (1/4" to 3 1/4").
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 P osiLok raise/lower control assemb ly
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. An engine-off switch (Item 22
Fig. 3) located next to the handle lock allows the operator to
safely turn the engine off from the operator's position and away
from moving parts.
ENGINE
Pages 23-27 highlight fundamental aspects of engine inspection,
starting, and shutdown. Refer to the engine Owner's Manual for
specific instructions regarding operation, service and
maintenance.
For maximum performance and return on investment use:
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.

FCG1 CONCRETE SAW — BLADES
SPECIFIC TOOLS TO BE USED
This saw is to use tools (blades) as follows:
Steel Core Segmented or Continuous Diamond Rim
Cutting Wheel.
Any other type of tool is not to be used. See Table 4 for specific
blade usage for material.
WARNINGWARNING
WARNING
WARNINGWARNING
Failure to thoroughly inspect the
diamond blade (Figure 11) for
operational safety could result in
damage to the blade, the saw , and ma y
cause injury to the user or others in the
operating area. All damaged blades
must be discarded.
1. Drive Pin Hole – A commonly located hole on the diamond
blade core that prevents operational blade slippage
between the inner & outer blade flanges (collars). Inspect
the diameter of the hole to ensure there is no distortion,
and that a snug fit develops between the hole and drive
pin.
2. Stress Relief Holes (Gullets) –
cracks that may have propagated from the slots and/or
gullets. Cracks indicate extreme fatigue failure and if sawing
continues, catastrophic failure will occur.
3. 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. Check to
make sure the steel core’ s width is unif orm 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.
4. Directional Arrow – Check to ensure that the blade is
oriented properly on the blade shaft for sawing. Reference
the directional arrow in the blade and place it so the direction
of rotation “downcuts” with the turn of the shaft.
Check the steel core for

in the operating area.
6. Specifications – Ensure that the blade specifications, size,
and diameter properly match up to the sawing operation.
Utilizing a diamond blade not matched properly to the task
may result in poor performance and/or blade damage.
7. Arbor Hole – It is essential that the arbor hole diameter
properly matches the blade, and that it is free from
distortions. Correct blade flanges (collars) must be used.
The inside face of the flanges must be clean & free of debris.
An out of round arbor condition will cause damage to the
blade and the saw.
8. MAX RPM – This RPM reference is the maximum safe
operating speed for the blade selected. DO NOT use
blades rated at a lower rotational speed than the rated
RPM of the saw (6000 RPM). Exceeding the MAX RPM is
dangerous, and may cause poor performance and may
damage the blade. All blades must be designed to meet or
exceed the maximum spindle RPM.
