reverts to an energy-conserving low
pressure and volume output when no
hydraulic flow is being requested.
1. Install flow limiter in motor inlet. This
type of flow limiter, (also called a
velocity fuse) protects the hydraulic
motor from over-speeding by shutting
off the flow of oil if the flow rate
exceeds a predetermined amount.
NOTE: If necessary, the flow limiter can
be reset by placing the hydraulic circuit in
FLOAT to remove all pressure. Reduce
hydraulic flow setting before restarting.
2. Connect hydraulic hoses to tractor
as described in the OPERATION
SECTION of this manual.
3. Close motor needle valve by
loosening jam nut, screwing needle
valve clockwise until seated, then
tightening lock nut.
4. Adjust tractor flow control to its
minimum setting.
5. Move hydraulic lever to RETRACT
to start pump.
6. Close AGITATION CONTROL valve
after pump primes and begins to
develop pressure.
7. Adjust tractor flow control until the
desired pressure is reached, up to a
maximum pressure of 120 psi.
IMPORTANT: Do not run pump for
extended periods with outlet flow fully
blocked. Overheating and pump
damage can result.
The hydraulic driven spray pump is
adaptable to three different types of
tractor hydraulic systems. Use the
following guidelines to assist with setting
the pump for proper operation.
Before starting the setup procedure,
ensure that the solution tank contains at
least 50 gallons of liquid, and the control
valves are at the following settings:
PUMP INLET SELECTOR
<SOLUTION TANK>
INDUCTOR MIX (OPT)

SPRAYER PUMP SETUP
NOTE: The information in this section
pertains explicitly to the Ace brand hydrau-
lic driven spray pumps. While set-up for
Hypro pumps is similar to the Ace set-up
please refer to exact Hypro manual for
specific instructions.
This type of system is most commonly
found on new, larger horsepower tractors.
It is characterized by use of a variable-
displacement hydraulic pump, which
