SILICOSIS/RESPIRATORY WARNINGS
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metaland
other materials with silica in their composition may give
off dust or mists containing crystalline silica. Silica is a
basic component of sand, quartz, brick clay, granite and
numerous other minerals and rocks. Repeated and/or
substantial inhalation of airborne crystalline silica can
cause serious or fatal respiratory diseases, including
silicosis. In addition, California and some other
authorities have listed respirable crystalline silica as a
substance known to cause cancer. When cutting such
materials, always follow the respiratory precautions
mentioned above.
WARNING
Grinding/cutting/drilling of masonry, concrete, metaland
other materials can generate dust, mists and fumes
containing chemicals known to cause serious or fatal
injury or illness, such as respiratory disease, cancer,
birth defects or other reproductive harm. If you are
unfamiliar with the risks associated with the particular
process and/or material being cut or the composition of
the tool being used, review the material safety data
sheet and/or consult your employer, the material
manufacturer/supplier, governmental agencies such as
OSHA and NIOSH and other sources on hazardous
materials. California and some other authorities, for
instance, have published lists of substances known to
cause cancer, reproductive toxicity, or other harmful
effects.
Control dust, mist and fumes at the source where
possible. In this regard use good work practices and
follow the recommendations of the manufacturers or
suppliers, OSHA/NIOSH, and occupational and trade
associations. Water should be used for dust
suppression when wet cutting is feasible. When the
hazards from inhalation of dust, mists and fumes cannot
be eliminated, the operator and any bystanders should
always wear a respirator approved by NIOSH/MSHA for
the materials beingused.

FCG16HA SAW • OPERATION AND PARTS MANUAL — REV. #1 (03/19/10) — PAGE 11
GENERAL INFORMATION
Intended Use
Operate the FCG16HA 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 FCG16HA 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 FCG16HA
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 FCG16HA has been engineered to
operate a powerful GX200 Honda Gasoline engine and 10"
diameter diamond blades. This special design allows for fast/
clean cuts in different materials at depths from 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 FCG16HA
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. 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
Refer to the engine Owner’s Manual for specific instructions
regarding operation, service and maintenance.
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.

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 may
cause injury to the user or others in the
operating area. All damaged blades
must be discarded.

1. Stress Relief Holes (Gullets) –
Check the steel core for
cracks that may have propagated from the slots and/or
gullets. Cracks indicate extreme fatigue failure and if sawing
continues, catastrophic failure will occur.
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. Check to
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 – 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.
4. Diamond Segment or Rim – Ensure there are no cracks,
dings, or missing portions of the diamond segment/rim. DO
NOT
use a blade that is missing a segment or a portion
the rim
of
. Damaged and/or missing segments/rims may
cause damage to your saw, and injury to the user or others
in the operating area.
5. Specifications – Ensure that the blade specifications, size,
and diameter properly match up to the sawing operation.
