PROPOSITION 65 WARNING
Engine exhaust and some of
its constituents, and some dust created
by power sanding, sawing, grinding,
drillingandotherconstructionactivities
contains chemicals known to the State
of California to cause cancer, birth
defects and other reproductive harm.
Some examples of these chemicals are:
Leadfromlead-basedpaints.
Crystallinesilicafrombricks.
Cementandothermasonryproducts.
Arsenicandchromiumfromchemically
treatedlumber.
Your risk from these exposures varies,
dependingonhowoftenyoudo this type
of work. To reduce your exposure to
these chemicals: work in aALWAYS
well ventilated area, and work with
approved safety equipment, suchas
dust masks that are specially designed
to filter out microscopic particles.

SILICOSIS WARNING
WARNING
SILICOSIS WARNING RESPIRATORY HAZARDS
Grinding/cutting/drilling of masonry, concrete, metal and
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, metal and
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.
SP1G CONCRETE SAW • OPERATION MANUAL — REV. #3 (09/07/17) — PAGE 3
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 being used.

GENERAL INFORMATION
INTENDED USE
Operate the SP1G 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 blade during sawing operations). The use
of a High Efficiency Particulate Air (HEPA) dust collector
must be attached to the blade guard discharge port during
operations.
FAMILIARIZATION
This lightweight, compact, and productive 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 saw 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 saw has been engineered to
operate with a powerful 5.5 HP Honda gasoline engine
with Cyclone Air Filtration. It includes a 10-inch diameter,
green concrete diamond blade. The green concrete blade
allows for fast and clean cuts in concrete recently poured
(4 to 12 hours) at depths from 1/4 inch to 3 1/4 inches.
The precision-machined, reinforced cast frame and steel
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, synthetic neoprene wheels
with permanently sealed bearings that are greaseable, and
solid undercarriage assembly, provide years of reliable use.
The SP1G incorporates an innovative posi-lock raise/lower
system that provides precise control of blade orientation.
This system further allows for infinitely adjusting blade
depth control and depth gauge.
The SP1G has a unique front pointer bar that ensures
optimum sawing accuracy. For operator comfort and ease
of transportation and storage, an adjustable locking handle
bar with vibration damping is provided. It also has a lifting
handle for ease of transportation.
Operator control of the saws is safely accomplished with
adjustable handle bars, and a conveniently oriented raise/
lower lever and depth adjustment lever. A shut-off switch
is 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.
For maximum performance and return on investment, use

WARNING
NEVER operate the saw without blade
guards and covers in place. DO NOT
operate with the front of the blade guard
raised. The blade exposure cannot exceed
180 degrees during operation. Adhere to the
safety guidelines of the American National
Standards Institute (ANSI) B7.1 and B7.5.
V-belt Alignment and Tensioning
This concrete saw is equipped with a premium V-belt that
has been aligned and tensioned by factory personnel. The
V-belt must be aligned and tensioned for proper operation
of the saw.
Use the following procedure to check the alignment of
V-belt:
1. Remove the bolts that secure the V-belt cover (Figure 5)
to the saw frame.
Figure 5. V-Belt Cover
Figure 4. Blade Guard
Check the following on the blade guard (Figure 4):
Ensure the capacity of the blade guard matches the
diameter of your diamond blade.
Check that the guard is bolted firmly upon the saw frame.
V-BELT CHECK
A worn or damaged V-belt can adversely affect the
performance of the saw. If the V-belt is defective or worn,
replace the V-belt as outlined in the maintenance section.
CAUTION
NEVER attempt to check the V-belt with the
engine running. Severe injury can occur.
Keep fingers, hands, hair and clothing
away from all moving parts.
2. Check uniform parallelism (Figure 6) of V-belt and
pulley (sheaves). Use a straight-edge or machinist's
square against both pulleys and adjust both pulleys
until equally aligned.
Figure 6. Pulley Alignment
3. Check V-belt tension by using a tension meter
(6.0 – 9.0 lbs.) against the inside belt at a mid point
between the two pulleys, or by deflecting the center
belt at a mid point 3/8" (10 mm) to 1/2" (13 mm). See

WARNING
Failure to thoroughly inspect the
diamond blade 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.
NOTICE
Adhere to the blade manufacturer's recommendations
on handling, storage, and safe usage of blades.

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 of
the rim. 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.
Utilizing a diamond blade not matched properly to the task
may result in poor performance and/or blade damage.
6. 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 and free of
debris. An out of round arbor condition will cause damage
to the blade and the saw.
7. 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.
