11� When baeries are
being charged or
discharged, they
generate hydrogen
and oxygen gases. This
combinaon of gases
is highly explosive. DO
NOT SMOKE around
baeries—STAY AWAY
FROM FLAME—don’t
check baeries by shorng terminals as the spark
could cause an explosion. Connect and disconnect
baery charger leads only when charger is “o”.
Be very careful with “jumper” cables.
12� Baeries contain strong sulfuric acid—handle
with care. If acid gets on you, ush it o with
large amounts of water� If it gets in your eyes,
ush it out with plenty of water immediately and
get medical help�
13� Hydraulic uid under
high pressure leaking
from a pin hole are
dangerous as they can
penetrate the skin as
though injected with
a hypodermic needle�
Such liquids have a
poisonous eect and
can cause serious
wounds� To avoid hazard, relieve pressure before
disconnecng hydraulic lines or performing work
on system. Any uid injected into the skin must
be treated within a few hours as gangrene may
result� Get medical assistance immediately if
such a wound occurs� To check for such leaks,
use a piece of cardboard or wood instead of your
hand. Make sure all hydraulic uid connecons
are ght and all hydraulic hoses and lines are
in good condion before applying pressure to
system. Wear protecve gloves and safety glasses
or goggles when working with hydraulic systems�
14� The ne spray from a small hydraulic oil leak can
be highly explosive—DO NOT SMOKE—STAY
AWAY FROM FLAME OR SPARKS.

1� The selecon of the vehicle on which a spreader
body is to be mounted has important safety
aspects. To avoid overloading:
a� Do not mount spreader on a chassis which,
when fully loaded with material to be
spread, will exceed either the Gross Axle
Weight Rang (GAWR) or the Gross Vehicle
Weight Rang (GVWR) for the chassis.
b� Do install the spreader only on a vehicle
with cab-to-axle dimension recommended
for the spreader body length shown�
2� Follow mounng instrucons in the Installaon
secon of this manual. If mounng condions
require deviaon from these instrucons refer to
factory�
3� When making the installaon, be sure that the
lighng meets Federal Motor Vehicle Safety
Standard (FMVSS) No. 108, ASABE S279 and all
applicable local and state regulaons.
4� When selecng a PTO to drive hydraulic pump, do
not use a higher percent speed drive than indicated
in the Installaon secon of this manual. Too high
a percent PTO will drive pump at excessive speed,
which can ruin the pump, but more importantly,
will overheat the hydraulic oil system and increase
the possibility of re.
5� When
truck frame must
be shortened, cut
o only the poron
that extends behind
rear shackle in
accordance with the
truck manufacturer’s
recommendaons. If
a torch is used to make
the cut, all necessary precauons should be taken
to prevent re. Cuts should not be made near
fuel tanks and hydraulic oil reservoirs, fuel, brake,
electric or hydraulic lines and such lines should
be protected from ame, sparks or molten metal.
Tires should be removed if there is any chance
of their being struck by ame, sparks or molten
metal. Have a re exnguisher handy.
GENERAL SAFETY RULES-INSTALLATION
6� Do not
weld on
vehicle
frame
as such
welding
can lead
to fague
cracking
and must be avoided� When drilling holes in frame
member, drill only through the vercal web porons
do not put holes in top or boom anges. Refer to
truck manufacturer’s recommendaons.
7� Be sure that welds between mounng bars and sill or
between mounng angles and spreader cross sills are
sound, full llet welds. Center mounng angles so
that good llet welds can be made on three sides—
and edge bead weld is not a sasfactory weld for this
service� Use 309 rod/wire for carbon steel and 409
steel. On 304 stainless steel bodies use SAE grade 5
bolts—welding is recommended if type 308 welding
rod is available�
8� Install
controls so that they are located of convenient use�
Posion them so that they do not interfere with any
vehicle control and that they do not interfere with
driver or passenger or with access to or exit from the
vehicle�
9� Check for vehicle visibility, especially toward the rear�
Reposion or add mirrors so that adequate rearward
visibility is maintained�
10� Add Cauon, Warning, Danger and Instrucon decals
as required. Peel o any label masking which has not
been removed�
11� Install all guards as required�
12� Check installaon completely to be sure all fasteners
are secure and that nothing has been le undone.

WARNING
Do not use one manufacturer’s hose with another manufacturer’s ngs! Such will void
any warranty and may cause premature burst or leak of hydraulic uids! Severe injury and/
or re could result!
WARNING
DO NOT check leaks with hands while system is operang as high pressure oil leaks can be
dangerous! If skin is pierced with hydraulic uid at high pressure seek immediate medical
aenon as uid injected into the skin could cause gangrene if le untreated. Relieve
pressure before disconnecng hydraulic lines or working system. Make sure all hydraulic
uid connecons are ght and all hydraulic hoses and lines are in good condion before
applying pressure to the system. Wear protecve gloves and safety glasses or goggles when
working with hydraulic systems�
WARNING DO NOT check for hydraulic leaks adjacent to moving parts while system is operang as
there may be danger of entanglement!
11� Check all connecons in hydraulic system to make sure there are no leaks.

The following procedure is a guide:
1� Field test over any suitable course which allows vehicle to be driven at speeds to be used while spreading�
2� Make sure unit has been properly serviced, that oil reservoir is full and gate valve under reservoir is fully open.
Do not load spreader�
3� Manual spinner control valve: Set to posion “5”.
PWM spinner control valve: Run at 550 RPM.
DANGER
Take proper safety precauons when observing conveyor and spinner speed while vehicle
is in moon! These may include use of suitable mirrors clamped to permit observaon by a
safely seated observer, following the spreader in another vehicle at a safe distance, or other
suitable means� Do not stand on fenders, in body or on any part of spreader as there is
danger of falling o the vehicle or into moving parts! Use great care in performing this test!
4� Start truck engine. Turn control to ‘’on’’ posion. Engage PTO and allow to run at fast idle long enough to bring
hydraulic oil up to operang temperature. Spinners should revolve at moderate speed and the conveyor should
not move�
5� Set program in control console to operaonal mode and begin forward travel. Move conveyor switch on
console to ‘’on’’ posion. Conveyor should start immediately when vehicle moves and should connue to run at
speeds which vary directly with the vehicles eld speed; the conveyor should speed up as truck speed increases
and slow down as truck speed reduces� Spinner speed should remain constant when engine speed is above
minimum operang range.

1� Make sure unit has been properly serviced and is in good operang condion. Field test unit prior to rst use,
prior to each spreading season’s use, and following overhaul or repair work, to verify that all components and
systems are funconing properly. See Field Tesng secon.
2� Fill body with material to be spread�
3� Drive to locaon where spreading is to be done.
4� Adjust spinner control valve for material being applied to give spread width desired. See G4 Spread Paern
secon.
5� Adjust spinner to give spread paern desired. See G4 Spread Paern secon.
6� Set feedgate opening to obtain the yield desired. Measure actual material depth.
7� Make sure shut-o valve on hydraulic reservoir is fully opened.
8� Turn on power to controller and set program to desired values�
9� Engage pump drive PTO�
CAUTION Drive only at speeds which permit good control of vehicle!
10. Drive at speeds that allow engine to run at proper RPM.
Higher transmission gears may be used with speeds to 30 MPH (48 KMPH). If lower speeds must be used, shi
transmission into lower gears so engine speed can be maintained to allow adequate hydraulic oil delivery from
pump�
NOTICE! CHANGE THE HYDRAULIC OIL FILTER AFTER THE FIRST WEEK (OR NOT MORE THAN 50 HOURS) OF
OPERATION ON A UNIT.

PREVENTATIVE MAINTENANCE PAYS!
The handling and spreading of commercial ferlizers is a most severe operaon with respect to metal corrosion.
Establish a frequent, periodic preventave maintenance program to prevent rapid damage to spreading equipment.
Proper cleaning, lubricaon and maintenance will give you longer life, more sasfactory service and more economical
use of your equipment�
WARNING Shut o all power and allow all moving parts to come to rest before performing any
maintenance operaon.
HYDRAULIC SYSTEM
Proper oil in the hydraulic system is one of the most important factors for sasfactory operaon. Utmost cleanliness
in handling the oil cannot be stressed enough� Keep hydraulic oil in original closed containers, clean top of container
before opening and pouring, and handle in extremely clean measures and funnels.
Refer to Lubricant and Hydraulic Oil Specicaons secon for selecon of the proper hydraulic uid for use in the
hydraulic system�
SERVICE SCHEDULE
WARNING
DO NOT check leaks with hands while system is operang as high pressure oil leaks can be
dangerous! If skin is pierced with hydraulic uid at high pressure seek immediate medical
aenon as uid injected into the skin could cause gangrene if le untreated. Relieve
pressure before disconnecng hydraulic lines or working system. Make sure all hydraulic
uid connecons are ght and all hydraulic hoses and lines are in good condion before
applying pressure to the system. Wear protecve gloves and safety glasses or goggles when
working with hydraulic systems�
1� Check hydraulic oil daily by means of sight gauge on reservoir. Add oil as necessary to maintain level around
mid-point of sight gauge. Periodically inspect hoses and ngs for leaks.
NOTICE! Change hydraulic oil lter aer rst week (or not more than 50 hours) of operaon on a unit.
2� Aer rst lter change, replace lter when indicator reaches Red Zone.
3� Drain reservoir through drain plug (not through sucon outlet), ush, and rell and change lter element
annually. Oil and lter should also be changed whenever oil shows any signs of breaking down under connued
high-pressure operaon. Discoloraon of oil is one sign of breakdown.
