THIS SAW IS SHIPPED FROM THE FACTORY WITHOUT A CATALYTIC CONVERTER. THE DIESEL 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.

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. CAUTION DIESEL FUEL Use Low Sulfur Diesel (0.05% or 500 ppm) or Ultra Low Sulfur Diesel (0.0015% or 15ppm) Biodiesel While ≤ 5% blends (B5) are preferred, biodiesel concentrations up to a 20% blend (B20) in petroleum diesel fuel can be used in all John Deere engines. Biodiesel blends up to B20 can be used ONLY if the biodiesel (100% biodiesel or B100) meets ASTM D6751 (US), EN 14214 (EU), or equivalent specification. Expect a 2% reduction in power and a 3% reduction in fuel economy when using B20.

Lower the saw by pressing the Raise/ Lower Switch (1N) on the Speed Control Lever (1M) downward until the Diamond Blade (2E) is at the desired cutting depth (See “Blade Cutting Depth Information”). Be certain that water flow is abundant for wet sawing. Blade Cutting Depth Information: The saw is equipped with a BLADE DEPTH INDICATOR (1O) which has two number ranges. The Orange and White number ranges are used for two different purposes:

1) The “Depth” number range, indicated by the Orange

color, shows the current Cutting Depth of the DIAMOND BLADE (2E). As the saw is lowered, the BLADE DEPTH INDICATOR (1O) needle travels through these numbers in increasing order. Or

2) The “SMD” or “Set Maximum Depth” number range,

indicated by the White color, is the uncut depth of the DIAMOND BLADE (2E). The desired maximum cutting depth is pre-set using the BLADE DEPTH INDICATOR (1O). It can be used with or without the BLADE DEPTH STOP SWITCH (1K) feature. As the saw is lowered, the BLADE DEPTH INDICATOR (1O) needle travels through the White color number range in decreasing order, indicating the unfinished depth of cut. When the BLADE DEPTH INDICATOR (1O) needle reaches “0” position, the desired maximum cutting depth is reached. If the BLADE DEPTH STOP SWITCH (1K) feature is used (“1” or “ON” position), the lowering process stops automatically. Using the BLADE DEPTH INDICATOR (1O): “Depth” Mode (Orange colored numbers show current cutting depth):

• Turn ENGINE START SWITCH (1C) to “0” (OFF) position to STOP engine (If running).
• Turn ENGINE START SWITCH (1C) to “1” (RUN) position to power electrical system.
• Turn BLADE DEPTH STOP SWITCH (1K) to “0” (OFF) position.
• Lower DIAMOND BLADE (2E) by pushing the TOGGLE SWITCH (1N) on the SPEED CONTROL LEVER (1M)

The saw WILL NOT lower to any depth greater than the position set on the BLADE DEPTH STOP SWITCH (1Q). If a deeper cut is required, the BLADE DEPTH INDICATOR (1Q) MUST be turned to the new depth position. Or push the BLADE DEPTH STOP SWITCH (1M) to “0” (OFF) position to override the Depth Stop Feature. downward until the DIAMOND BLADE (2E) touches the surface to be cut.

• Rotate the BLADE DEPTH INDICATOR (1O) needle to align to the “0” depth.
• As DIAMOND BLADE (2E) is lowered into the cutting surface, the current cutting depth will now be indicated by the Orange text number range on BLADE DEPTH INDICATOR (1O) needle. SMD or “Set Maximum Depth” Mode without BLADE DEPTH STOP (White colored numbers show uncut depth):
• Turn ENGINE START SWITCH (1C) to “0” (OFF) position to STOP engine (If running).
• Turn ENGINE START SWITCH (1C) to “1” (RUN) position to power electrical system.
• Lower DIAMOND BLADE (2E) by pushing TOGGLE SWITCH (1N) on the SPEED CONTROL LEVER (1M) downward until DIAMOND BLADE (2E) touches the surface to be cut.
• Rotate the BLADE DEPTH INDICATOR (1O) needle to align with the desired maximum cutting depth on White colored number range. The uncut depth will now be indicated on the White colored number range. When the BLADE DEPTH INDICATOR (1O) needle gets to the “0” position, the saw is cutting at the desired maximum cutting depth.
• Raise the blade by pushing the TOGGLE SWITCH (1N) on the SPEED CONTROL LEVER (1M) upward until the DIAMOND BLADE (2E) is off of the cutting surface.
• Turn the ENGINE START SWITCH (1C) to the “0” (OFF) position to turn off power to electrical system. SMD or “Set Maximum Depth” Mode using BLADE DEPTH STOP SWITCH (1O) (White colored numbers show uncut depth):
• Turn ENGINE START SWITCH (1C) to “0” (OFF) position to STOP engine (If running).
• S et the BLADE DEPTH STOP SWITCH (1K) to the “0” (OFF) position to override the depth stop setting. Saw will raise and lower over its full range without stopping.
• Turn ENGINE START SWITCH (1C) to “1” (RUN) position to power electrical system.
• Lower DIAMOND BLADE (2E) by pushing TOGGLE SWITCH (1N) on the SPEED CONTROL LEVER (1M) downward until DIAMOND BLADE (2E) touches the surface to be cut.
• Rotate the BLADE DEPTH INDICATOR (1O) needle to align with the desired maximum cutting depth on White colored number range.
• Set the BLADE DEPTH STOP SWITCH (1K) to “1” (ON) position.
• Raise the blade by pushing the TOGGLE SWITCH (1N) on the SPEED CONTROL LEVER (1M) upward until the DIAMOND BLADE (2E) is off of the cutting surface.
• Turn the ENGINE START SWITCH (1C) to the “0” (OFF) position to turn off power to electrical system.
• Now the maximum cutting depth is set. If the saw is raised out of the cut surface for any reason it can now be lowered to “Set Max. Depth” by lowering the blade until the saw lowering movement stops.

Stopping The Saw (See Figures 1-2) For EMERGENCY STOP, press down the RED PALM SWITCH (1J) on the cowl. This will stop the engine and disconnect power to all electrical items except lights. Reset the RED PALM SWITCH (1J) by pulling out until it pops up, then restart engine.

SINGLE SPEED GEARBOX MODEL: Each saw model, as delivered from the factory, is designed to operate with a specified range of blade sizes inside the blade guard installed on the machine. If a blade size outside the specified range of sizes for your model must be used, then the saw drive configuration must be changed. If changing from a small to a very large DIAMOND BLADE (2E) on a machine with a single speed gearbox, the Blade Shaft Pulleys (3-1L), Gearbox Pulleys (3-1N), the BLADE SHAFT FLANGES (2B & 2F), and the Blade Guard must be changed. For example, to change a single speed gearbox model from a 18” (450mm) drive to a 36” (900mm) drive:

1. Change Engine Gearbox Pulley from 4.75” (121mm)

diameter to 3.65” (93mm) diameter.

2. C hange Blade Shaft Pulley from 4.12” (105mm)

diameter to 5.60” (142.2mm) diameter.

3. Change Blade Flanges from 5.00” (127mm) diameter

to 6” (152mm) diameter.

4. Change BLADE GUARD (2H) from 18” (450mm) to

5. Engine Speed does not change.

See Blade Size Conversion charts for specific information. THREE SPEED GEARBOX MODEL (14-26, 18-30, 20-36, 26-42, 30-48, 36-60): CAUTION: Never shift the Gearbox (3-2A) with engine running! Only shift the Gearbox (3-2A) with engine OFF! Gearbox damage could occur. See “GEARBOX SHIFT LEVER (3-2O)” for details about operating shift lever. A machine factory equipped with a Three Speed ENGINE GEARBOX (3-2A), while designed to minimize adjustments required for blade size changes, will require some adjustments. The machine is designed to operate with a specified range of blade sizes inside the factory installed blade guard. Color coded information on machine, and information in operation manual, shows allowable blade sizes for current machine drive configuration. There are six (6) machine drive configurations: a) 14-26 for 14” to 26” (350 to 650 mm) blades, b) 18-30, for 18” to 30” (450 to 750 mm) blades, c) 20-36, for 20” to 36” (500 to 900 mm) blades, d) 26-42 for 26” to 42” (650-1000 mm) blades, e) 30-48 for 30” to 48” (760-1219 mm) blades f)36”-60” (900-1500mm)(FS 8400 D). For example, to change the blade size on a machine drive configuration 18-30 within these range, 18” to 30” (450 to 750 mm), requires only that GEARBOX SHIFT LEVER (3-2O) be moved into the correct position (1, 2, or 3). If the required blade size is outside of the machine drive configuration range [below 18” (450mm) or above 30” (750 mm) for this example], then the machine drive configuration must be changed. This may require shifting the GEARBOX SHIFT LEVER (3-2O), changing BLADE SHAFT PULLEYS (3-2L), GEARBOX PULLEYS (3-2N) and BLADE SHAFT FLANGES (2B & 2F). Example: To change a three-speed gearbox model from a 20” (500mm) drive to a 36” (900mm) drive, first determine the machine drive configuration (14-26, 18-30, 20-36, 26-42, or 30-48). This should correspond to the BLADE SHAFT FLANGE (2B & 2F) diameter installed on the saw. If the machine drive configuration is a 20-36, the FLANGE (2B & 2F) diameter is should be 6.00” (152mm): a) Verify proper pulley diameters are installed (See Blade Size Conversion charts for specific information). b) Shift the GEARBOX SHIFT LEVER (3-2O) from 3 to 1. c) Verify that machine drive configuration and blade shaft speed corresponds with information in operation manual, and gearbox range decal (522627702). If the machine drive configuration is an 18-30, the FLANGE (2B & 2F) diameter should be 5.00” (127mm): a) Change the BLADE SHAFT PULLEY from 4.12” (105 mm) diameter to 4.75” (121mm). b) Change the BLADE SHAFT FLANGE from 5.00” (127mm) diameter to 6.00” (152mm). c) Shift the GEARBOX SHIFT LEVER (3-2O) from 2 to 1. d) Verify that machine drive configuration and blade shaft speed corresponds with 20-36 drive configuration information in operation manual. e) Install the 20-36 drive configuration decals (Decal 522627704 is required). See the “Decals and Locations” page of this manual for more information. If the machine drive configuration is a 14-26, the FLANGE (2B & 2F) diameter should be 4.50” (114.3mm): a) Change the BLADE SHAFT PULLEY from 4.12” (105mm) diameter to 4.75” (121mm). b) Change the BLADE SHAFT FLANGE from 4.50”

(114.3mm) diameter to 6.00” (152mm). c) Change the ENGINE GEARBOX PULLEY from 4.75” (121mm) diameter to 4.12” (105mm). d) Shift the GEARBOX SHIFT LEVER (3-2O) from 2 to 1. e) Verify that machine drive configuration and blade shaft speed corresponds with 20-36 drive configuration information in operation manual. f) Install the 20-36 drive configuration decals (Decal 522627702 is required). See the “Decals and Locations” page of this manual for more information. See Blade Size Conversion charts for specific information.

WARNING: Serious injury can occur to the

operator or people in the work area if the rotational speed (n/min) of the DIAMOND BLADE (2E) exceeds the maximum speed (n/ min) marked on the DIAMOND BLADE (2E).

Large Diameter Models The FS8400 can be configured with a 60” (1500mm) diameter blade capacity. The 60” drive can be ordered from the factory or can be reconfigured by ordering the conversion kit 542 19 96-25. See the Blade Size Conversion Chart for specifics. Depth of cut of 25” can be achieved. The large diameter model includes a frame extension, 60” blade guard and a blade shaft assembly with 10” If gearbox seems hard to shift, a slight movement of the blade shaft may ease movement of GEARBOX SHIFT LEVER (3-2O) into proper gear. Never shift the Gearbox (3-2A) with engine running! Two Neutral positions are available in the Three Speed ENGINE GEARBOX (3-2A). This gearbox can be shifted into neutral if the blade rotation needs to be eliminated while the engine is running. If the machine is equipped with the optional BLADE CLUTCH (1Y), the BLADE CLUTCH SWITCH (1Y) can be moved to the “0” (OFF) position to eliminate blade rotation while the engine is running.

diameter flanges. The Flanges have the following pattern. The Blade Hole pattern must match. Six (6), ½-13 x 2.5” long Hex Head Cap Screws pass through the outer flange through the blade core and thread into the inner flange supplying the clamping force to hold the blade. Use ½” lock washers with the clamping bolts. Also use the 5/8-11 x 4.0” Cap Screw, LH or RH thread through the center of the flange. Husqvarna will supply blades with this hole pattern. The FS8400, when equipped with a 60” drive system is very heavy and the machine balance is greatly affected by installing or removing a blade. To counter the large balance changes, a weight box is mounted on the left or right rear of the saws. Weights can be easily removed and added to quickly adjust the machine balance to meet the operator’s needs.
