HYDRAULIC FEED CONTROL
Because of the great stiffness of the 2 5/8 and 3 inch blades used on most
H-40 saws, these saws are provided with a factory preset feed force limit
which protects the blade against overloading. This leaves the operator with
only one control - the Feed Rate Knob and one digital display - the Feed Rate
Indicator. Both the knob and indicator are located on the console.
The Feed Rate Knob controls how fast the head will fall without any stock
under the blade - the “Free Fall Feed Rate.” This is also the feed rate which will
arise when the blade is cutting thin to moderate cross-sections. When wide or
hard cross-sections are encountered, the feed rate will be automatically
reduced by the internal feed force limit circuit.
SETTING THE FEED RATE KNOB
Correct setting of the feed rate knob is critical to achieving good sawing
performance and blade life. If the Feed Rate setting is too
low, time and blade
life will be wasted. If the setting is too high, each tooth will get too big of a “bite”
and tooth strippage will result.
Determining the correct Feed Rate to set is a 4 step process which
includes setting the blade speed and choosing the correct blade pitch (or
compensating for the one you have to use). These steps are explained in the
following pages.
MACHINES with SERVO VALVES
When an H-40 saw is equipped to use a 2 inch blade, “Servo Valves”
mounted on the blade guides are required to adequately protect the narrower
blade. This is just a somewhat more involved feed force limit circuit and does
not affect the way in which the operator uses the Feed Rate Knob.

VARIABLE SPEED CONTROL
Blade speed can be adjusted infinitely between 75 and 270 SFPM (Surface Feet/Minute) on the H-40. The
remote blade speed adjustment, adjustment is made using the BLADE SPEED dial located on the control panel.
The blade speed is displayed on the Digital Display.
