Safety Guidelines
• Use genuine factory parts or parts
with equivalent characteristics, includ-
ing type, strength and material. Fail-
ure to do so may result in product mal-
function and possible injury to the op-
erator and/or others.
• If hardware is not secure, or if some of
the hardware is over-tightened, equip-
ment failure may result, posing poss-
ible safety hazards.
• To prevent possible eye injury, always
wear SAFETY GLASSES while oper-
ating equipment.
• Replace locknuts and locking screws if
you can tighten them without feeling
considerable resistance for several
turns before they are completely tight.
Replace them with factory authorized
parts or their equivalent.
Guards & Shields
• Keep all safety devices in place.
• Replace all worn, damaged, unusable,
missing or lost safety shields and
guards before operating the equip-
ment.
• Keep the equipment in good operating
condition.

provided by the manufacturer and
we do not recommend removing
them for any reason. See parts
page 1.5.
Safety Decals
• If safety related or instructional decals
become illegible or are removed, re-
place them immediately. New decals
may be obtained from your local Harp-
er Dealer.
• If you replace parts that have such
decals attached to them, make sure
the decals are replaced with current
versions, and are on the replacement
parts before the machine is operated
again.
Hydraulics
To prevent serious injury or death:
• Relieve pressure on system before
repairing, adjusting or disconnecting
any hydraulic hose or tting.
• Wear proper hand and eye protection
when searching for leaks.
• Use wood or cardboard instead of
hands when looking for leaks.
• Keep all hoses, ttings and compo-
nents in good operating condition.
• Do not use any type of heat or ame
(welding, soldering, cutting torch, etc.)
near pressurized hydraulic lines.
SAFETY WARNING!
HIGH-PRESSURE FLUID HAZARD!
Escaping uid under pressure can pene-
trate skin causing serious injury or death.

SAFETY WARNING!
OPERATING THE S3 LIFTING ARM WITH
THE TABLE IN THE ROAD/TRANSPORT
POSITION WILL DO DAMAGE TO THE LIFT
ARM LINKAGE!
Fig. 4
Fig. 5
For PTO machines we
have installed a PTO stand for
your convenience. It also
contains key slots for your
hydraulic hoses. The PTO shaft
rests in the cutout on top of the
stand and the hydraulic hoses
insert into the key slots. When
using S3, be sure PTO stand is
in down (working) posi-
tion. Do so by pulling pin
and pushing down. Then
reinstall pin.
Operation
NOTE: BEFORE OPERATING YOUR NEW
S3 MAKE A COMPLETE INSPECTION OF
ALL COMPONENTS TO INSURE THAT ALL
THE NUTS AND BOLTS ARE TIGHT AND
THAT NO DAMAGE HAS OCCURRED DUR-
ING SHIPPING.
HYDRAULIC REQUIREMENTS
Your new DEWEZE S3 is designed to be
used as a mobile feeding unit mounted on a
trailer or as a stationary unit in a permanent
installation. Regardless of the type of use
the S3 WILL REQUIRE 15 GPM (gallons per
minute) of hydraulic oil ow and a minimum
of 1800 PSI (pounds per square inch) hy-
draulic pressure to operate properly. Be sure
that the hydraulic system you intend to use is
functioning properly and that the oil is clean
and of good quality.
Two hydraulic remotes are required to oper-
ate the trailer mounted S3. One is to control
the lift arm for loading the bales and the other
is to operate the slicer table. Each remote
must be capable of reversible ow. You may
want to mark the remotes to make sure that
you hook up the hydraulics the same way
each time you use the machine.
NOTE: When using a hydraulically driven
S3 continuously (for more than 3 bales in 10
minutes) the following adjustments must be
made to tractors equipped with a high ow,
pressure compensated load
sense hydraulic system.

LOADING INSTRUCTIONS
(Trailer Mounted Unit Only)
Approach the bale on its right side with the
lift arm lowered to the ground. Cradle the
bale in the lift fork by moving forward so that
the bale is against the back of the fork. Lift
the bale all the way up so that the bale rolls
onto the table slats. Move the bale toward the
sickle by activating the feeder and stop as the
bale reaches the sickle. To load and carry a
second bale, repeat the above process and
raise the second bale until it rests snuggly
against the rst.
NOTE: Be sure to raise the lift arm to the
upright position and latch the safety chain
whenever you transport your S3 on the road!
FEEDING INSTRUCTIONS
To engage the feeding operation of the S3,
idle the tractor engine, engage the slicer table
hydraulics and increase the engine speed to
the tractor manufacturer’s suggested rated
speed. On a PTO slicer the PTO RPM is 540.
To engage the PTO we recommend idling the
engine, engaging the PTO then accelerating
the tractor’s engine to rated speed for correct
540 PTO RPM operation.
SAFETY WARNING!
Stay clear of the table and cutter bar when
the machine is in operation!
If the system stalls, reverse the slats and try
again.
NOTE: Always wait until the rst bale has
been processed completely and the table
slats have stopped before loading the second
bale onto the table.

1. Flow (speed) must be controlled on
the tractor remote outlet. To set this
speed rst set the Slicer ow as
outlined in the manual. Secondly,
turn the ow control toward the “turtle”
on the tractor selective control outlet
until the speed begins to decrease.
Stop turning as soon as you can notice
a decrease in speed. Failure to follow
these procedures may result in the
overheating of the tractor hydraulic
system, as the system will be at
maximum ow and pressure. (Load is
sensed at the tractor selective control
valve and if this valve is wide open the
system is at constant maximum
pressure / ow.
2. The alternative to the above is to buy a
“ow limiter valve” and attach it
between the quick disconnect and the
hose on the pressure side.
3. On PTO model S3, ow must also be
regulated at the selective control outlet
for the slat motor.
NOTE: If the above instructions are not fol-
lowed, the following symptoms may develop:
Rapid heating of the tractor hydraulic
oil, this will show up as a loss of speed
on the hydraulic motor speed. These

Suggestion: When adjusting the sickle and
the backboard sliding with it, loosen the bolts
and nuts shown. There are nuts, bolts, and
straps on both the front and rear sides of the
machine.
3. Retighten the four 5/8” bolts loosened
in step one on previous page.
FLOW CONTROL VALVE ADJUSTMENT
The ow control valve on the right controls
the speed of the sickle. Loosen the knob on
the valve to adjust the lever and move the le-
ver to a higher number to increase the speed.
To lower the number is to decrease speed.
After moving the lever, tighten the knob to
hold the lever in place.
For initial setting of the valves, set each
adjusting lever on “2”. Fine tune the speed of
the sickle and slats by adjusting the valves
individually to get the proper cutting for the
type of hay you are processing.
FEEDING RATE
The feeding rate may be adjusted by chang-
ing the speed of the feeder chain, or by
adjusting the distance between the sickle and
the table slats. To change this distance, use
the following procedure.
SAFETY WARNING!
Turn off tractor and disconnect the hydrau-
lic hoses before making any adjustments
to the sickle! Failure to do so could result
in serious personal injury!
1. Loosen the two 5/8” hex bolts (1) and
two 5/8” carriage bolts (2) that hold the
sickle bar in place. (See Fig. 3)
2. Screw the 3/4” all thread adjustment
bolts (3) in or out at each end of the
sickle. Make sure that each end is
adjusted so that the sickle is parallel
with the table slats. Use a tape
measure to gauge each end.
