torque values.
See Figure 1 to determine the correct amount of
spreading material for the regular capacity hopper
spreader.

GENERAL INFORMA TION
Determining Vehicle Payload 4.
5
6.
With the occupants in truck for nonnal
hopper spreaderoperation, weigh vehicle to
obtain grossvehicle weight (GVW).
Subtractthe GVW from the GVWR to
detennine the available payload to carry the
material.
Obtain the weight per cubic yard (lb./cu. yd.)
of the desired material from Table 2, page4.
UseTable 3 to record information.
I. Install hopper spreaderandoptional
equipment according to the instructions.
2. Install or attachany other equipment that will
be on the vehicle while the hopper spreader
will be in use(stepbumper, trailer hitch,
snowplows, etc.).
Fill gastanks.
3. Obtain the GrossVehicle Weight Rating
(GVWR), Front GrossAxle Weight Rating
(FGAWR), andRearGrossAxle Weight
Rating (RGAWR) from the certification label
located inside the driver-side door jam.
Divide the weight into the payload to
detemline the maximum volume of material
that can be carried.
7. Compare the maximum volume to Figures I
or 2 on page 4 to determine the maximum
height of the material in the hopper spreader.
8. Fill hopper with the material to the height
calculated. Re-weigh vehicle with occupants
and verify the GVW, Front Gross Axle
Weight, 'and Rear Gross Axle Weight are less
than the vehicle's ratings.
9. Repeat steps 7 and 8 for each type of material.
Refer to Table 3 on page 6 for an example and
worksheet.

OPERA TION
Cab Control Identification 8When the engine starts,releasethe ignition
switch.
NOTE: If the enginedoesnot start after 10
secondsof cranking, turn both vehicle and
spreaderignition switchesto OFF and seethe
Briggs & Stratton Owner's Manual that is
shipped with the spreader.
Figure 3
9. After theengine starts,move the throttle
switch to IDLE andhold for 1/2 -1 secondto
releasethe choke.
10.To control the engine speed:
.Increase: hold the throttle switch at
CHOKFlFAST .
.Decrease: hold the throttle switch at IDLE.
N OTE: Maximum engine speed is obtained
just prior to choking the engine.
NOTE: The conveyor and spinner will
operatewhen the clutch switch is in the ON
or BLAST position.
Engine Operation
Refer to Figure 3 asareferencefor starting and
stopping the engine.
Starting the Engine
Stopping the Engine
1. Move the throttle to illLE and hold for two
seconds.
2. Turn the spreader ignition switch to OFF.
NOTE: Readandunderstandthe engine
manufacturer's Owner's Manual before
starting theengine.
Turn the vehicle ignition switch to ON.
2. Verify the clutch switch is OFF.
4.
5.
Turn the spreaderignition switch (labeled
"Engine" on the cab control) to ON.
Move the throttle switch to IDLE andhold
for two seconds;release.
Turn the spreaderignition switch to START .
While the engine is cranking, move the
throttle switch to CHOKE/FAST .
When the enginestartsto fire, releasethe
throttle switch.
Form No.80324 7November1,1996

OPERA TION
Clutch Operation Baffle Adjustment
.Start the engine.
2. Adjust the speedto slightly above idle.
3. Move the clutch switch to ON.
Spreadpattern and the amount of material
dispenseddependson engine RPM, gateposition,
andbaffle settings.
.Decreasing RPM and/or gate-opening will
decreasethe amount of material coming to
the spinner.
.Increasing RPM and/or gate-opening will
increasethe amount of material coming to
the spinner.
SeeFigure 4, andFigures 5 and6 on thenext
page.
4. Increasethe engine speedto the desiredRPM.

MAINTENANCE
General
At the endof the season,oil or paint all
baresurfacesafter washing andbefore
storing theunit.
Grease
.Maintain spinner shaft-to-gear caseroller
chain tension. Correct chain tension allows
5/16" deflection midway betweenthe
sprockets.SeeFigure 7.
To increase chain tension: loosenthe
bearing mounting hardware andpull the
spinner shaft away from the gearcase.
Make surethe spinner shaft is vertical and
the sprocketsarelined up before
re-tightening the fasteners.Oil this chain
after eachuse,andat the endof the season.
Figure 7
.Maintain engine-to-electric clutch roller
chain tension. Correct tension allows 5/16"
deflection midway between sprockets. See
Figure 8.
.Use dielectric greaseon all electrical
connections at the beginning andendof
eachseason,andasrequired during the
season.
.After every lO hoursof operation, grease
the idler bearingson the idler shaft,
flanged bearingson the drive shaft and the
input shaft abovethe gearcase,and the
spinner shaftbearings.
.After every 50 hours of operation, grease
the input shaft bearingon the gearcaseand
verify the oil level of the gearcaseis level
with thefill hole.
.Change gearcaseoil once a year. Drain oil
by removing the sidecover of the gear
case.Refill with SAE 90 weight gearoil.
Oil level should beevenwith the fill hole.
Chains
At the beginning of eachseason,and once
a month during the season,verify the drive
sprocketsetscrewsaretight.
Figure 8
To increase chain tension: loosen the four
engine mount-to-engine base bolts and pull
the engine away from the electric clutch.
Re-tighten bolts. Oil this chain after each
use, and at the end of the season.
Form No.80324 10 November 1 , 1996

MAINTENANCE
Electric Clutch
Periodically check the conveyor chain
tension.
To checkthetension, measurein 201'-24"
from the rearedgeof the sills. Pushup on
the chain with your hand.The conveyor
chain should lift 1"-3" off the conveyor
chain guide or crossangles.SeeFigure 9.
To minimize problems and extendthe life of the
electric clutch, do the following:
.At the endof eachsnow season,remove
and clean the clutch.
.After cleaning the clutch, coat both
mating surfacesof the clutch with oil or
light grease.
.Remove oil and greaseprior to using the
clutch again.
Engine Service and Repair
Maintain the spreaderengine according to the
Briggs & Stratton Engine Owner's Manual that
is shipped with the spreader.Engine warranty is
covered by Briggs & Stratton and is describedin
the back of the manual.
If service or repair is needed,contact an
authorized Briggs & Stratton Service Center.To
serveyou promptly, the Service Center will need
the model, type, and code number for your
engine.
Your nearestservice center is listed in the
"Yellow Pages"under "Engines, Gasoline" or
"Gasoline Engines."
Figure 9
.Use the (2) 5/8" x 6" take-up bolts at the
front of the spreader to adjust the conveyor
chain tension. Turn both sides equal
amounts to ensure the tension is equally
distributed across both sides of the
conveyor chain.
.Always empty the spreader when it is not
in use to prevent a frozen conveyor chain.
