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).

WARNING: After Shifting Gearbox, lower GEARBOX DETENT KNOB (3-2P) or three- speed ENGINE GEARBOX (3-2A) could be damaged!

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 (1V), the BLADE CLUTCH SWITCH (1V) can be moved to the “0” (OFF) position to eliminate blade rotation while the engine is running.

16 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”

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.
