Husqvarna FSA 8400 D Starting The Saw, See Figures 1, 2, Blade Cutting Depth Information

To Remove A SLIP-ON GUARD:

•Using the Blade Shaft Wrench remove the rear retaining bolt.

•Slip the Blade Shaft Wrench between the guard and the belt guard onto the latch lever. Raise the lever to unlatch and lift guard off spade.

To Install A SLIP-ON GUARD:

6 Starting The Saw

(See Figures 1, 2 and 5)

Always pay extreme care and attention to the preparation of the machine before starting.

Remove all wrenches and tools from the floor and the machine.

Always keep blade guard, belt guards and fan guards in place.

•Follow all operating instructions and warnings in this manual and on the machine.

•Close the Water Valve (1T).

•Mark the surface to be cut by drawing a line where the cut is to be made.

•Pull out Handle Bars (1B) to desired length and tighten Knobs (1A).

•Lower the Front Guide (6D) and align the Front Guide (6D), Rear Guide (6F) and Diamond Blade (2E) with the line on the surface.

•To start the saw when no water pressure is present, set the Water Safety Switch (1L) to “0” (OFF).

•Set Speed Control Lever (1O) to the STOP (1BB) position. Saw will not start unless the Speed Control Lever (1O) is in the STOP (1BB) position. Check to be certain the Transmission Bypass Valve (5M) is closed in the down position.

•Set the Blade Clutch Switch (1V) to “0” (OFF) (if equipped).

•Start the engine using the Engine Start Switch (1H). Follow the procedure in the engine manual.

In Cold conditions, pre-heat the engine glow plugs by hold in the Engine Start Switch (1H) for 15 seconds.

•Let the engine warm up for several minutes with Engine Throttle (1F) at the low speed setting.

•When ready open the Water Valve (1T).

•Set Water Safety Switch (1L) to “1”(ON).

Test for adequate water supply. (2.5 - 5.0 GPM) (10 - 20 Liters per Min.) Low water flow will cause damage to diamond blades.

•Pull Throttle (1F) out to set engine RPM at 3000.

See chart for the appropriate blade shaft and engine speeds for specific blade sizes.

•Move the saw forward or reverse slowly by pushing or pulling on the Speed Control Lever (1O). Move the saw slowly to prevent stalling the blade. Make sure the Front Guide (6D), Rear Guide (6F) and Diamond Blade (2E) stay on the line.

•Set the Blade Clutch Switch (1V) to “1” (ON) to engage the Blade Drive (if equipped) ONLY AT IDLE SPEED OF ENGINE!

•Lower the saw by pressing the Raise/Lower Switch (1P) on the Speed Control Lever (1O) 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 (1Q) 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 (1Q) 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 (1Q). It can be used with or without the BLADE DEPTH STOP SWITCH (1M) feature. As the saw is lowered, the BLADE DEPTH INDICATOR (1Q) needle travels through the White color number range in decreasing order, indicating the unfinished depth of cut. When the BLADE DEPTH INDICATOR (1Q) needle reaches “0” position, the desired maximum cutting depth is reached. If the BLADE DEPTH STOP SWITCH (1M) feature is used (“1” or “ON” position), the lowering process stops automatically.

Using the BLADE DEPTH INDICATOR (1Q):

“Depth” Mode (Orange colored numbers show current cutting depth):

•Turn ENGINE START SWITCH (1H) to “0” (OFF) position to STOP engine (If running).

•Turn ENGINE START SWITCH (1H) to “1” (RUN) position to power electrical system.

•Turn BLADE DEPTH STOP SWITCH (1M) to “0” (OFF) position.

•Lower DIAMOND BLADE (2E) by pushing the TOGGLE SWITCH (1P) on the SPEED CONTROL LEVER (1O) downward until the DIAMOND BLADE (2E) touches the surface to be cut.
