TRI-PLOW COMPONENTS
BLADE
The tw blade wings on your new TRI-PLOWare constuctd of heavy
gage steel. To increase rigidit and stength t each wing is reinforced
with several vertica ribs. The top edge of each wing is rolled for
added strength and improvd appearance.
The exccusive Ron.Acon TM blade is designed to roll snow ahead and
to th side instead of just pushing snow. This action gives your
vehicle a power reserve as it moves snow easily. You move more
snow and mov it faster using less power l saving fuel and reducing
wear and tear on both truck and plow.
Blade life is extended wit rep'aceable high cabon steel cuttng
edges bolted to the bottom of each wing. Periodically switch cutting
edges to the opposi wing to equalize wear. Cutting edge ends are
rounded to help ride ovr obscles and prevent digging and gouging.
The blade also features heavy duti adjustblet disc.ty skid shoes.
Thes rotate 36 for longer wear and better blade flotation over all
surfaces. See the Care & Maintenance seon for adjustent.
Your new TRI-PLOWblade is protected with PRQ.GUARD™ - a
baked-on poder finish that resists crackings corrosion, scratching
and rust. The PROGUARD nn coating - many times thicker than paint -
will maintain its luster and gloss goo looks longer than any other
snowlow blade finish in the indust.
Blade guides wit replaceable flags are furnished with your TRI..
PLOW.. These help improv operator visibilty and blade control.
BLADE POSITIONS
The TAlPLOW can be use in fie basic plowing positions:
1. Straight Blade. move boh wings to form a straight blade
for wide path plowing or "stckingU snow. Use this position
to transport plow between job sites.
2. Angled Blade.. Move one wing "OUT" and the other wing
"IN" to form an angled blade in either direcon for general
plowing and widening.
3. 11V" Blade.. Mov both wings "INIt towrds the vehicle for ¡ni.
tial break through plowing and plowing paths or walkways.
4. Scp Blade. Move both wings ClOUT" away from the
vehicle to form a scp to Ucarr" snow wi minimum spil.
loft.
5. Doleg BBade - Move one wing to straight blade position
and the other "OUT" to scp blade position for clean up of
windrows.
For best road clearance, the straight blade position is recmmended
dunng transport. The scp and "V' positions are NOT RECOM-
MENDED during transport.

MAST It A-FRAME
Blade wings are hinged at the Mast. The A-Frame connec the mast
to the vehicle. The mast attaches to the stong triangular shaped A-
Frame with a 1 n diameter rivet and heavy dut trip springs. Heavy 1"
diameter hitc pins are use to seure the A-Frame to th vehicle
mount. These hitc pins can't be bent and wil not shear in normal
operation, assuring a solid connection.
Three heavy duty trip springs hold the mas vertcal to the ground.
The springs are a safety device which anow the bladei when in certin
positions (see page 9), to trip forwrd and ride ovr obstcles such as
low curb, manhole covers, etc., wiout damage to the. blade wings,
vehicle or injury to the driver. Eye bolts are use to adju'st the tension
of the trip springs.
UFT-MOUNT
WESTERN(§ has designed custom lif-mount assmblies for most
vehicles. Due to diferences between vehicce models, there is only
limited interchangeabilit of lif-mount assmblies.
The mount is fasened to the underside of the vehicle frame and
provides the primar connecing link betwn the snowppow and the
vehicle. The tift provides the mounting framework for the hydraulic
unit and is mounte on top of the front extensions of the vehicle
frame.

TRI-PLOW VALVE
Your TR~PLOW includes an elecicaly operated TRI-PlOW Valve to
give you full control of blade wing positioning. When wing position-
ing is caled for by the ilia Control, fluid from the lsmatiC( Mark ila
unit is direced by this vaa to one of the double actng cyinders at-
tached between a wing and the A-Frame.
The TRI-PLOW Valv has tw cushion valves built in to prevent
damage to the blade wings or your vehice if obstacles are hit. When
force against the blade causes pressures in the cynnder to exceed se
limits, the cushion valv allow oil to escpe and the cyinder rod
retract. The blade is proteced in certn positions (see page 9). Plow-
ing sped should not exceed 5 MPH. .
NOTE
If a wing moves inward while plowingi 00 NOT change cushion valve
settng.
AWARNING: DO NOT stand ben the

TIPS ON USING THE TRI-PLOW
Oprating a vehicce equippe with a TAl-PLOW is not difficlt if you
follow these few simple suggestions -
Be sure you know of any obstuctons hidden beneath the
snow - bumper stops in parking lots, abutments, curbs,
sidewalk edges, shrubs, fences, or pipes sticking up from
the ground. Rag these if necessry to prevnt an accdent
or damage to plow or vehicle.
AWARNING: Drer mus alWys wer sebelt whn plng sno. A hidden obsc-
tloncould caus the vehicle to stop suddenly.
Head, nek or bo Injury can resuh from hltng
the windshield, dah or steering wh.
Plow wit the storm rather than lettng snow accmulate.
AWARNING: Never plow wth head out of thvehlc window. Sudden stopa or protrud-
In objec could cause sever. neck or head
InJuries.
Overheating is unlikely under normal driving conditions. Oc-
casionally, however r the plow may be in a position where
air is deflected away from the radiator. Stop the vehicle and
raise or lower the plow slightly to correc overheating.
Auxilary headlights and direconal lights provide added
safety and better lighting for night work and are a National
Highway Traffc Safety Administration (NHTSA) require-
ment. Before transit, adjust the raised blade height for maxi-
mum ilumination from auxilary lights.
Hard packed snow - for bettr clean up. raise the disc
shoes so that the cuttng edge comes into direc contact
with the pavement. Use lowst gear to place maximum
power behind cuttng edge.
Deep snow coditons - move the blade into the uy- posi-
tion and raise plow 3 to 4 inches for the inital pass. aean
up and widen the initial pass with angle, scp or dogleg
blade as the situation reuires. VVen plowing dep snow J
be sure to keep vehice moving. Ballast is required for max-
imum tracton. Se Stp 1 of UCountdown for Plowing.,
page 14.
Stcking snow - mov th blade into the scop or staight
blade poiton. As the ustcking" location is approached,
begin raising th blade to st the ride-p onto th stck.
NOTE: Stacking snow with either wing in less than straight
blade positin could reslt in damage to the bumper.
Drveways and sidewalks - make first pass wih the wings in
the 'VI position. Widen as required using NV"1 angle, scp
or dogleg blade as the situation requires.
Traveling - for normal travel to and from jobs! carry the
blade in the staight poition. DO NOT carr blade in scp
or uV" position. For long trips, the blade should be
removed from the front of the vehicle.

www.storksplows.com

The tw mos common snowplowing sites are drivways and parking
lots. General direcions for clearing both areas are detaiied below.
aearing Driveways
1. Head into driv with blade in uV-. Stay to building side of
drive. Widen driv by roUing snow away from building wi
angled blade.
2. If garage is at end of drivewayi plow up to within seral
vehicle lengths of garage. Then push as much snow as pos~
sible off drieway.
3. Wit raise straight blade, dri through remaining snow to
building. Drop blade and uba-drag'l snow away from
garage door at leas one vehicle lengt. Repeat If nec
sa.
4. Back vehicle to garage door and wit angle or scp blade
plow forward toward streei removing remaining snow from
drieway. Check municipal ordinans for dispsing of
snow.
Clearng Pang Lots
1. Oear areas in front of buildings firs. IlBack..rag" near
walls. Work away from buildings towards outer edges of tot.
2. Mae multiple pas with the blade in th uy- posion to
create windrows.
3. Move the blade into the dogleg or scp poon to "ca"
snow to end of fot. As the ustcking "loction is ap
proched, begin raising the blade to strt the ride-up onto
the stack.

COUNTDOWN FOR pLOWING
Before the snow flies, check your equipment and make sure it's ready
for action. Here's an 8 Step Countdown for gettng your equipment
set for the snowplowing seasn -
8. Check hydraulic sysm for leaks and cracked or damaged
hoses. Chec oil level (plow in IV' and lif ram NOT col-
lapsed). Replace worn or defecve part.
7. Check all mountings of snowlow to vehicce - tighten fas-
teners.
6. Repaint mountings with rust resistnt, high grade enamel.
Touch-up blade wit WESTERN~ Re Paint available in
aerosol or quart can.
5. Check windshield wipers, heaters, headlights and auxilary
lights.
4. Install auxilary and flashing lights for safet. Vehice head-
lamps should be aimed wihout plow attched to the
vehicle. Plow headlamps should be aimed with plow at-
tached and in raised poition.
3. Us chains on tires if additional traction is needed.
2. To permit TRI-PLOWto rise and fall (foat) wih contour of
ground, push lift channel all the way down. Pull chains
tight and hook them to the lif channeL. Afer they are
hooked, they wil have the correc amount of slack for plow
"110at" .
AWARNING: Inspe 11f channel and bon.
whnever hoong or unhoking the plow,
and before traveling. Worn or damaged com..
ponents could result In the plow dropping to the
pavement while driving causing an accident.
1. We suggest a minimum of 50 pounds ballast for pick-up
trucks...NOW HEAD FOR THE SNOW!
SAFE OPERATING RULES-
TRANSPORTING PLOW
Plow vehicle should be equipped wit all vehicle manufactrerJs op-
tions for snowplowing.
1. Only the driver should be in the vehicle when plow is at-
tached for plowing or during transprt.
2. When transporting plow, engage ila Control lock to prevent
plow from being lowered accdentty.
3. Under ideaf road conditions, transporting plow should be
within posted road spes. Reuce sp when crossing
railroad tracks i road irregularities, or as road conditions
deteriorate.
4. For normal trave to and from jobsi carry the blade in
staight blade position. DO NOT ca plow in scp or 'V'
positions. For long trps, the plow should be removed from
the front of the vehicle.
AWARNING: Beore traveling, pohlon bladeso " doe not block headlamp beam. Do
not change blade pohlon while traveling. Incor-
rec plow pohlon blocking head lamp bem can

prevent possible damage to housing or paccdngs due to 011
expansion. Persnal injury cold result from sudden brade
drop.
SAFETY AROUND THE BLADE
1 Do not std between the vehicce and the blade when it is
. being raise or angled. Clearance between vehicle and
blade is deceased as blade is raised or wings moved "IN".
2. Do not place hands, feet or any par of body under raise
blade. Acdental lowering could cause injury.
3. Keep people clear of blade when raising or positioning
blade wings.
REMOVING OR MOUNTING BLADE
1. PJways use care when disconnecng or connecing TRI-
PLOW from/to vehicle. Keep feet and hands ccear when any
part is in motion.
2. Inspe lif channel and bolts whenever hooking or unhook-
ing the blade, and before traveling. Worn or damaged com-
ponents could result in the blade dropping to the pavement
whife driving causing an accdent.
3. Do not place finger in hitch pin holes to check alignment.
Any sudden motion of the TRI-PLOW could severely injure a
finger.
4. Keep people clear of blade when raising or positioning
blade wings.
SERVICING VEHICLE OR PLOW
