JACK POSITIONING Lift the machine up with the three-point hitch, remove the
jack stand pin and turn the jack stand back, not forward, into its neutral position
(or remove jack stand if desired). Replace jack stand pin. Fold the jack stand arm
up to keep it away from the working area as shown in Figure 6. The Surf Rake
®
is
now ready for operation. See Figure 6.
TRACTOR ENGINE While in operation, the tractor engine should be kept at an RPM that will result in a 540-
RPM PTO speed. This should be displayed on the tractor's tachometer. The speed of the tractor and the
PTO speed will later be adjusted to suit individual beach.
CONTROL VALVE The control valve is located between the pump and conveyor belt
motor. It raises or lowers the speed of the conveyor belt motor by regulating the flow of
hydraulic fluid circulated by the pump. The adjustable control knob is on the top, rear of
the valve. Turning the knob counter clockwise opens the valve inside and the conveyor
belt increases in speed. Turning the knob clockwise lowers the belt speed. There is a
built-in, preset, pressure relief valve that protects the conveyor belt assembly from
objects that may become wedged during cleaning. If an oversized or wedged object
stops the rotation of the conveyor belt, the valve will open, relieving pressure from the
conveyor motor and bypass the hydraulic fluid back to the reservoir. There is also a
reversing knob on the top, front of the valve. To reverse the conveyor, pull up on the
knob while the PTO is engaged. The automatic finisher is also operated from the
control valve. When the PTO is engaged, the finisher will lower to operating position
and raise when the PTO is disengaged.
