SILICOSIS/RESPIRATORY WARNINGS
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.
SP1 PAVEMENT SAW • OPERATION AND PARTS MANUAL — REV. #0 (01/04/10) — 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 SP1 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.
GENERAL INFORMATION
The SP1 Saws are designed for wet or dry cutting of
concrete or asphalt utilizing Diamond Blades. These saws
have been engineered for general and industrial flat sawing
applications.The reinforced steel box frame design adds
strength necessary to reduce blade vibrations while cutting.
By minimizing blade vibrations the performance of the blade
is enhanced and thus the life of the blade is extended.
Heavy-duty front and rear axles, sturdy oversized wheels,
and industrial undercarriage assembly ensure accurate
tracking and years of reliable use.
Additionally, the general strength-to-weight ratio design
of the frame and chassis assembly provides for optimum
weight distribution to keep the blade running true in the cut.
A rugged spindle bearing assembly ensures minimal flutter
and shaft harmonics providing the most advantageous
condition for a diamond blade at operating speeds.
This saw comes equipped with an 18-inch blade guard and
handles Diamond Blades ranging in size from 12-18-inches
in diameter.
POWER PLANTS
The SP1 saw is generally considered a "low" powered saw
in the industry. This classification is particularly useful when
selecting the proper diamond blade for an application.
This SP1 saw is powered by a HONDA GX390U1QWT2
air cooled, 4-stroke, single cylnder, OHV gasoline engine
rated at 11 HP (8.2 kW) at 3,600 RPM.
Refer to the HONDA Engine Owner's Manual for specific
information regarding engine operation and maintenance
procedures.
BLADE ROTATION
Three premium 3VX belts connecting a properly sized drive
(engine) pulley and an output blade shaft pulley provides
the rotational power of the diamond blade. Specific pulley
diameters have been chosen to support the design of the
SP1 saw.
Ultimate blade shaft RPM speed is very important for the
safe, efficient operation of the diamond blade in the cut.
All SP1 SAW S ar e desig ned, engi neer ed and
manufactured with strict adherence to American
National Standards Institute, Inc. (ANSI) guidelines
B7.1 and B7.5.

INSPECTION/SETUP
Guards And Covers
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 or other applicable local regulations.
V-Belt Check
A worn or damaged V-belt can adversely affect the
performance of the saw. If a V-belt is defective or worn,
replace ALL the V-belts. V-belts should always be replaced
in sets.
WARNING
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.
V-Belt Alignment and Tensioning
This saw is equipped with premium V-belts that have 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:
Figure 7. Blade Guard (Right-side mounting)
Blade Guard Inspection
CHECK the following on the Blade Guard (Figure 7)
Ensure the water feed tubes are properly positioned to
permit water flow to both sides fo the diamond blade.
Check that the guard is bolted firmly upon the saw frame.
Check that the spring tensioned front cover of the guard
is firmly seated with the rear section of the guard and
there are no gaps. NEVER lift the blade guard while
engine is running.
ENSURE the V-Belt Cover is in place and securely
fastened during operation of the saw (Figure 8).
1. Remove the bolts that secure the V-belt cover (Figure
8) to the saw frame.
Figure 8. V-Belt Cover
2. Check uniform parallelism (Figure 9) of V-belt and
pulley (sheaves). Use a straight-edge or machinist's
square against both pulleys and adjust both pulleys
until equally aligned.
PAGE 22 — SP1 PAVEMENT SAW • OPERATION AND PARTS MANUAL — REV. #0 (01/04/10)
INSPECTION/SETUP
3. Check V-belt tension by using a tension meter (3.0
lbs./1.36Kg) against the inside belt at a mid point
between the two pulleys, or by deflecting the center
belt at a mid point 3/16" (5 mm).
Figure 9. V-Belt Alignment
4. DO NOT over or under tighten the V-belts. Severe
damage can occur to the saw and engine crankshaft
if the belt is over-tensioned. A decrease of power to
the blade and poor performance will result if the belt
is under-tensioned (loose on pulleys).
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 5 for
specific blade usage for material.
WARNING
Failure to thoroughly inspect the diamond
blade (Figure 10) for operational safety
could result in damage to the blade or
the saw, and may cause injury to the user
or others in the operating area. Discard
damaged or worn blades and replace with fresh
blade.
NOTICE
V-belt alignment must be rechecked after adjusting
belt tension.

BLADES
Figure 10 highlights the components of a diamond blade.
Figure 10. Diamond Blade
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.
5. Diamond Segment or Rim – Ensure there are no
cracks, dings, or missing portions of the diamond
segment/rim. DO NOT
a segment or a portion of the rim
use a blade that is missing
. Damaged and/
or missing segments/rims may cause damage to your
saw, and injury to the user or others in the operating
area.
6. Specifications – Ensure that the blade specifications,
size, and diameter properly match up to the sawing
operation. Wet blades must have water to act as
a coolant. 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 shaft arbor, 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. NEVER exceed
the max RPM on the diamond blade. Exceeding
the MAX RPM is dangerous, and may cause poor
performance and may damage the blade. All blades
used must be designed for the maximum spindle
RPM.
2. 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.
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 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.
4. Directional Arrow – Check to ensure that the blade is
oriented properly on the spindle for sawing. Reference
the directional arrow on the blade and place it so the
direction of rotation “downcuts” with the turn of the
shaft.

BLADES
4. Outside Blade Flange (Collar) — Ensure that the
outside blade flange is placed flush against the
diamond blade. The inside surface of the flange must
be free of debris and permit a tight closure on the
surface of the blade core.
5. Diamond Blade — Ensure that the proper diamond
blade has been selected for the job. Pay close attention
to the directional arrows on the blade. The blade's
operating directional arrows must point in a "downcutting" direction to perform correctly. When placing
the blade onto the spindle, ensure the arbor hole of the
blade matches the diameter of the shaft.
6. Inner Flange (Collar) — This flange is fixed upon the
spindle. The inside surface of the flange must be free
of debris and permit a tight closure on the surface of
the blade.
