SiliCOSiS/reSpiratOry warningS
WARNING WARNING
SILICOSIS WARNING
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.
RESPIRATORY HAZARDS
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.
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.

BLADE GUARD
Figure 3. Blade Guard page 16 — Sp1e16a paVeMeNT SaW • operaTioN MaNual — reV. #0 (04/14/10)
Check the following on the blade guard (Figure 3):
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.
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 cutting.
Ensure the v-belt cover is in place and securely fastened during operation of the saw (Figure 4).
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.
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.
V-belt Alignment and Tensioning
This 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
4) to the saw frame.
inSpeCtiOn/Setup
2. Check uniform parallelism (Figure 5) 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 5. Pulley Alignment
3. Check V-belt tension by using a tension meter (3.0 lbs.) against the inside belt at a mid point between the two pulleys, or by deflecting the center belt at a mid point
3/16" (5 mm).
4. Do NoT over or under tighten the V-belt. 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).
NOTICE
V-belt alignment must be rechecked after adjusting belt tension.

Saw blades, or cutting disks, are available in either an abrasive design or as diamond blades. Either blade will work on the SP1E16A, however, diamond blades are recommended. Ask your dealer about your specific cutting application.
WarNiNg
Failure to thoroughly inspect the diamond blade for operational safety could result in damage to the blades or the saw and may cause injury to the user or others in the operating area.
Figure 6 highlights the components of a diamond blade.
Figure 6. 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.
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.
blaDeS
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.
5. 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.
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 (1"), 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.
page 18 — Sp1e16a paVeMeNT SaW • operaTioN MaNual — reV. #0 (04/14/10)
BlaDe plaCeMeNT
1. Blade guard — Pivot the blade guard front cover all the way back. The guard tension spring will keep the front cover in position.
2. Blade Hex Nut — Unscrew the blade shaft nut (right side loosens clockwise and tightens counter-clockwise while the left side loosens counter-clockwise and tightens clockwise. DO NOT overtighten the nut
(approximately 45-50 ft. lb/61-68 N/m) when finalizing the assembly.
3. 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.
4. 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 blade shaft, ensure the arbor hole of the blade matches the diameter of the shaft.
5. inner Flange (Collar) — This flange is fixed upon the blade shaft. The inside surface of the flange must be free of debris and permit a tight closure on the surface of the blade.
BlaDe SpeeD
A diamond blade’s performance is directly connected to specific peripheral (rim) speeds.
The following shaft rotational speeds have been factory set to ensure optimum blade performance.

NeVer place hands or feet inside the belt guard or blade guard while the engine is running. alWayS shut the engine down before performing any kind of maintenance service on the saw.
1. Ensure the diamond blade has been mounted correctly and that it is raised above the surface you are about to saw.
2. Use an extension cord (see Table 3) of adequate current carrying capacity. Insert the electric motor’s power plug into one end of the extension cord.
CauTioN
MaKe CerTaiN that the electric motor's power switch is in the OFF position before plugging the motor into the power source.
blaDeS/initial Startup
DaNger .
NeVer touch the power cord with wet hands or while standing in water when it is connected to a power source.
The possibly exists of electrical shock (electrocution) or even death. NeVer spray water directly on the electric motor.
3. Plug the other end of the extension cord into a 230VAC power source. Remember to read the nameplate to determine the motor's input voltage requirement.
WarNiNg
alWayS read the label on the electric motor before applying power. The label will indicate the correct power requirements for the motor. Remember, the use of an incorrect input voltage will severely damage the electric motor.
MaKe CerTaiN the motor is connected to a functional ground fault circuit interrupter.
STarTiNg THe eleCTriC MoTor
1. Before starting, MaKe CerTaiN there is enough clearance between the blade and the ground.
2. Set the electric motor’s ON/OFF switch (Figure 8) to the ON position.

WarNiNg
alWayS keep clear of rotating or moving parts while operating this equipment.
OperatiOn/MaintenanCe
MaiNTeNaNCe
WarNiNg
alWayS ensure that the motor ON/OFF switch is in the
oFF position, the power cable is unplugged, and that the arbor shaft has CoMpleTely SToppeD roTaTiNg before performing any of the following operations:
NOTICE
MaKe CerTaiN to raise the spindle high enough for the blade to clear the pavement.
WarNiNg
MaKe CerTaiN the saw path is clear of debris and obstructions to prevent tripping and/or falling onto the saw, and to prevent debris from hitting the blade.
1. To begin sawing, lower the rotating blade allowing it to cut to the preset depth.
2. When the blade has reached full cutting depth, slowly walk behind the saw at a rate that will allow the motor to operate without losing optimum RPM.
CauTioN
Do NoT try to cut faster than the blade will allow.
Cutting too fast will cause the blade to rise up out of the cut. Improper cutting rate can decrease the life of the motor and blades.
NOTICE
Mark the cutting line clearly. oNly saw in a straight line.
3. When the end of the cut has been reached, raise the blade out of the cut by pulling back on the handlebars
(using a downward pressure) until the raise/lower rod drops into its slots with the blade in the raised position.
4. If cutting is complete, turn the motor off and wait for the blade to stop rotating.
SToppiNg THe SaW
1. Place the electric motor’s ON/OFF switch in the OFF position.
2. Disconnect the electric motor’s extension cord from its power source.

Inspecting, adjusting, or replacing drive belt, arbor shaft, or arbor shaft bearings
Saw Blade removal and installation
See "Blade Removal and Replacement" section in this manual.
Front pointer adjustment
CauTioN
alWayS ensure that unit is unplugged (disconnected) when installing blade.
The front pointer wheel has been set at the factory. Use these procedures only if the pointer is suspect of being out of alignment.
1. Chalk out a straight line on the prepared slab or cutting surface.
2. Use a 4 foot straight-edge or level by placing it flat against the blade.
3. Adjust the front pointer wheel so it just touches the side of the straight-edge or level.
4. Remove the straight-edge or level.
5. Position the front pointer and blade directly over the chalk line.
6. Start the saw and lower the blade onto the chalk line.
7. Begin cutting and make sure the blade follows the chalk line as closely as possible.
8. The pointer should follow the chalk line as well. If it does not, adjust the pointer by loosening then tightening the jam nuts on the pointer until the pointer follows the same path as the blade.

MaintenanCe/trOubleSHOOting (eleCtriC MOtOr)
Chassis lubrication
Blade Shaft Bearings — Two zerk fittings are located at the lower-front area of the saw. Lubricate before daily use. Use a good quality automotive or general purpose grease. Check and lubricate more often if unit is under heavy use. Do not overfill bearings. Overfilling can damage the grease seals which can result in bearing exposure to dirt and contaminants which can then shorten the life of the bearings. Excess grease can also drip onto the cutting surface.
V-Belt
