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.

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.
