DUST WARNING Cutting, especially when DRY cutting, generates dust that comes from the material being cut, which frequently contains silica. Silica is a basic component of sand, quartz, brick clay, granite and numerous other minerals and rocks. Exposure to excessive amount of such dust can cause:

Respiratory diseases (affecting your ability to breath), including chronic bronchitis, silicosis and pulmonary fibrosis from exposure to silica. These diseases may be fatal; Skin irritation and rash; and Cancer according to NTP* and IARC*

• National Toxicology Program, International Agency for Research on Cancer Take precautionary steps

Avoid inhalation of and skin contact with dust, mist and fumes; Wet cut when feasible, to minimize dust; Wear and ensure that all bystanders wear appropriate respiratory protection such as dust masks designed to filter out microscopic particles. (See OSHA 29 CFR Part 1910.1200) California Prop 65 Warning: Use of this product can cause exposure to materials known to the State of California to cause cancer and/or birth defects or other reproductive harm.

THIS SAW IS SHIPPED FROM THE FACTORY WITHOUT A CATALYTIC CONVERTER. THE ENGINE PRODUCES CARBON MONOXIDE EXHAUST EMISSIONS AND IS NOT SAFE FOR USE IN ENCLOSED AREAS. USE OF A CATALYTIC CONVERTER REDUCES THE CARBON MONOXIDE EXHAUST EMISSIONS, BUT STILL IS NOT SAFE FOR USE IN ENCLOSED AREAS. USE ONLY IN WELL-VENTILATED AREAS. WORKSITE AIR QUALITY MUST COMPLY WITH OSHA 29 CFR 1910.1000 PER TABLE Z-1, LIMITS FOR AIR CONTAMINANTS. MONITOR WORKSPACE AIR QUALITY TO INSURE COMPLIANCE. FAILURE TO COMPLY WILL RESULT IN DANGER TO LIFE AND CAUSE PERMANENT INJURY OR DEATH. General Information Carbon monoxide (CO) has the distinction of being one of the few commonly encountered industrial gasses that is both highly toxic (poison) and odorless. When inhaled, CO acts as a chemical asphyxiant by preferentially combining with hemoglobin in the blood stream. As a result, the hemoglobin is not able to transport its normal amount of oxygen, which results in under-oxygenation of tissues. Symptoms of low-level CO exposure include headaches, dizziness, confusion, and nausea. However, loss of consciousness, permanent injury and death may result from continued or more intense exposure. Because of the health hazards associated with CO inhalation, the Occupational Safety and Health Administration (OSHA) have imposed personal exposure limits. The OSHA exposure limits, which are specified in the 29 CFR 1910.1000 (1998 Revision), allow for a 200 PPM Ceiling Limit and a TWA of 35 PPM per 8-hour shift/40-hr workweek. It is strongly recommended that the OSHA 29 CFR 1910.1000 (Code of Federal Regulations) be consulted for more information on exposure limits for various hazardous materials. If CO Poisoning is suspected immediately remove the victim to fresh air and obtain emergency medical attention. Proper Ventilation: THIS SAW IS SHIPPED FROM THE FACTORY WITHOUT A CATALYTIC CONVERTER. It is important to be aware that saws with catalytic converters reduce CO and hydrocarbon (HC) emissions. The exhaust still contains CO. If the workspace is too confined or under-ventilated, CO may accumulate until it eventually exceeds OSHA limits. When this happens, action must be taken to remove workers from areas of high concentration. Operators and work area supervisors should take precautions to insure adequate ventilation of the workspace at all times. Carbon monoxide detection monitors should be used to determine that adequate ventilation exists. WARNING HEARING HAZARD DURING NORMAL USE OF THIS MACHINE, OPERATOR MAY BE EXPOSED TO A NOISE LEVEL EQUAL TO 85 dB (A) OR GREATER. TEMPORARY AND/OR PERMANENT DAMAGE TO HEARING MAY RESULT. HEARING PROTECTION REQUIRED.

MAINTENANCE & LUBRICATION SCHEDULED MAINTENANCE QUICK REFERENCE: Before performing any maintenance, ALWAYS park the machine on a level surface with the engine “OFF” and the engine switch set in the “OFF” position. Let the machine cool down! Other maintenance and repairs should only be carried out by a qualified technician. SERVICE DAILY:

1. Check engine oil level.

2. Check blade guard for damage.

3. Check engine air filter, replace if dirty. Service sooner

if used in dusty conditions.

4. Clean machine daily.

LUBRICATION: Depth Control Grease Fitting (X): A grease fitting allows lubrication of Blade Depth Control (EE) screw. To access this grease fitting:

• Raise the Diamond Blade (H) to maximum height. Open Tool Compartment (BB), temporarily remove operation manual bag.
• Grease fitting (X) is located near top of Blade Depth Control (EE) Tube.
• Add Grease to the fitting. Raise and lower the machine a few times to circulate the grease through the tube.
• Replace Operation Manual Bag, close Tool Compartment (BB) door. Engine Oil: Checking Engine Oil: Check that engine oil level is correct. Engine Oil Dipstick (Z) is located on front of engine. Refill engine oil in dipstick hole. When checking oil level, Engine Oil Dipstick (Z) should not be screwed in. Because engine often operates at an angle, check oil level with engine horizontal. Check frequently to ensure that oil level never falls below lower mark on dipstick. 10W30 oil is recommended. See engine operation manual for more information.

Replace engine oil and filter. Clean engine/motor air fins. Lubricate Depth Control Grease Fitting (X). Check wheels for wear or damage. Check blade drive belt tension. MAINTENANCE & LUBRICATION Changing Engine Oil:

• Turn machine Start Switch (DD) to OFF (0) position. Let engine cool. Use Depth Control (EE) to tilt machine slightly backwards.
• Reposition Oil Drain Hose (NN) to side of machine. Set a suitable container, large enough to hold engine oil capacity, beside machine to catch oil.
• Open end of Oil Drain Hose (NN), and let oil drain into container. After oil is drained, replace Oil Drain Hose (NN) end, tighten securely, return hose to original position.
• Fill engine with recomended quantity of oil - see engine manual for details.
• Dispose of used oil in an environmentally safe manner. Blade Shaft Drive Belt Tension: Drive Belt should be re-tensioned after first few hours of operation. Belt Drive Idler (MM) holds tension on Drive Belt. Tools Required:

• 13mm Wrench (Included with machine).
• 3/8” (9.53mm) Drive Torque Wrench (Not Included)
• 14mm Wrench (Not included with machine).

1. Use 13mm Wrench (U), to remove three (3) M8 bolts

that attach Belt Guard (LL). Remove Guard (LL).

2. Use the 13mm & 14mm wrenches to slightly loosen the

two (2) bolts that secure the Belt Drive Idler (MM) [bolts indicated by (2) arrows].

3. Attach Torque Wrench to square hole in Belt Drive Idler

4. Apply a torque to Drive Idler (MM) so that Drive Idler

(MM) is forced against the V-Belt. Torque to the value shown in diagram 4.

75 N-m (55 ft-lbs) FS 410 D

5. Tighten center bolt (CB1) to hold Drive Idler (MM) in

position, then tighten remaining bolt (CB2).

6. Reinstall Belt Guard (LL). Use 13mm Wrench (U), to

tighten three (3) M8 bolts that attach Belt Guard (LL).

MAINTENANCE & LUBRICATION Governor Speed It is critical that Governor and throttle on all internal combustion engines be adjusted properly. Engine speed is preset at factory for proper sawing speed. It is NOT normally necessary to change this setting. It should be periodically verified after machine is placed into service. To change the Governor setting, refer to the engine manual. WARNING! Overspeeding Diamond Blade (H) can result in blade breakage and/or personal injury to operator and bystanders! To assure proper Governor adjustment, determine correct blade shaft speed (RPM) from the adjacent chart. Follow engine manufacturer’s instruction procedure for Governor and throttle setting.

Engine Will Not Start: Cause Action Electrical switches not in correct position. Check that BOTH Emergency Stop Switch (AA) and Engine Start Switch (DD) are in “ON” position. Emergency Stop Switch (AA) should be pulled outward from cowl, and Engine Start Switch (DD) turned to “1” (ON) position. Fuel valve closed. Open the fuel valve. Choke valve open. Close the choke with cold engine. Fuel tank empty. Fill with fuel. Contamination, or water ice in fuel system. Clean tank, fuel lines and carburetor. Fill tank with fresh fuel. Buildup on spark plug electrodes. Check electrode gap and clean. Engine has no power or runs unevenly. Air filter Clogged. Clean or replace the air filter. Diamond Blade Trouble Shooting: Problem Loss of Tension in Diamond Blade Cause & Action Blade being used on misaligned saw. Check for proper saw alignment. Blade is excessively “hard” for material being cut, creating stress on steel blade center. Check that blade is correct for material being cut. Different diameter or undersize blade flanges creates uneven pressure on blade center. Use proper size flange on each side of blade. Never use worn or damaged flanges. Blade operated at improper speed (R.P.M.). Make certain blade shaft is turning at the proper speed (R.P.M.) for blade size. Check R.P.M. using a tachometer. Blade improperly mounted on arbor. Could become bent when flanges are tightened. Segment Loss Blade is too “hard” for material being cut. Use “softer” blade specification. Overheated blade, detected as “blue” color on steel center. Check that water supply is adequate and not blocked. Saw is twisted while cutting. Saw only in a straight line. Blade Bore is worn to an eccentric shape (ovalized). Replace worn blade and worn spindle. Segment knocked off during mounting our transport. Avoid rough handling of diamond blade. Never transport the machine with the diamond blade mounted. Cracked Blade Core Blade is too “hard” for material being cut. Use “softer” blade specification. Overheated blade, detected as “blue” color on steel center. Check that water supply is adequate and not blocked. Saw is twisted while cutting. Saw only in a straight line. WARNING! DO NOT use damaged diamond blades! Death or injury could occur if machine is operated using damaged diamond blades! Cracked Blade Segments Blade is too “hard” for material being cut. Use “softer” blade specification. Blade operated at improper speed (R.P.M.). Make certain blade shaft is turning at the proper speed (R.P.M.) for blade size. Check R.P.M. using a tachometer.
