HYDRAULIC CONTOUR FEED
Hydraulic-controlled contour feed provides power feeding for all types of contour
sawing, and is controlled by a handwheel and control valve on the table. This is a
factory installed attachment.
As shown above, the power feed guide roller bar is drawn by a hydraulic cylinder.
The valve which controls the hydraulic pressure varies the rate of feed from 0 to
15FPM. When the pointer of the valve handle (shown in sketch) is turned to the
right, the feed increases up to a maximum speed of 15FPM. The hydraulic feed
reverses when the control valve handle is turned to the returned position. The
handle should always be in the stop position when the hydraulic feed is not in
Use the contour control handwheel to turn the work and follow contours while it
is being pulled into the saw band.
(1) Check all hydraulic connections. Fill hydraulic tank with 2-1/2 gallons of
ESL anti-wear hydraulic oil.
(2) Put control valve in stop position and start hydraulic pump motor. Be sure
motor is running so that rotation is in same direction shown by arrow on motor.
This may be changed by reversing leads to machine.
(3) Move guide roller bar conected to piston rod back and forth by turning control
valve handle from feed Position to return position until system is com-
pletely filled with oil and free of air pockets. The hydraulic system is then
ready for operation.
