BEFORE ATTEMPTING ANY PROCEDURE IN THIS
BOOK, READ AND UNDERSTAND ALL THE SAFETY
INFORMATION CONTAINED IN THIS SECTION. IN
ADDITION, ENSURE ALL INDIVIDUALS WORKING
WITH YOU ARE ALSO FAMILIAR WITH THESE
SAFETY PRECAUTIONS.
For your safety Warning and Information Decals have
been placed on this product to remind the operator
to take safety precautions. It is important that these
decals are in place and are legible before operation
begins. New decals can be obtained from Sno-Way or
your local dealer.
REMEMBER The careful operator is the best
operator. Most accidents are caused by human error.
Certain precautions must be observed to prevent the
possibility of injury to operator or bystanders and/or
damage to equipment.
NEVER operate Plow when under the influence of
alcohol, drugs or other medications that could hamper
your judgement and reactions. An accident may result in
serious injury or death to other persons or yourself.
ALWAYS operate vehicle in a well-ventilated area. The
carbon monoxide in exhaust gas is highly toxic and can
cause serious injury or death.
NEVER allow hands, hair or clothing to get near any
moving parts such as fan blades, belts and pulleys.
Never wear neckties or loose clothing when working on
the vehicle.
NEVER wear wrist watches, rings or other jewelry when
working on the vehicle or individual equipment. These
things can catch on moving parts or cause an electrical
short circuit that could result in serious personal injury.
ALWAYS wear safety goggles when working on the
vehicle to protect your eyes from battery acid, gasoline,
and dust or dirt from flying off of moving engine parts.
ALWAYS be aware of and avoid contact with hot
surfaces such as engine, radiator, and hoses.
ALWAYS wear safety glasses with side shields when
striking metal against metal! In addition, it is
recommended that a softer (non-chipable) metal material
be used to cushion the blow. Failure to heed could result
in serious injury to the eye(s) or other parts of the body.
NEVER allow children or unauthorized person to
operate this unit.
NEVER exceed 45 m.p.h. when snow plow is attached
to vehicle. Braking distances may be increased and
handling characteristics may be impaired at speeds
above 45 m.p.h.
ALWAYS lock the vehicle when unattended to prevent
unauthorized operation of the plow.
ALWAYS check the job site for terrain hazards,
obstructions and people.
NEVER exceed 10 m.p.h. when plowing. Excessive
speed may cause serious injury and damage of
equipment and property if an unseen obstacle is
encountered while plowing.
ALWAYS position blade so it does not block path of
headlamps beam. Do not change blade positions while
traveling. An incorrect plow position blocking headlamp
beam may result in an accident.
ALWAYS check surrounding area for hazardous
obstacles before operating this unit.
ALWAYS inspect the unit periodically for defects. Parts
that are broken, missing or plainly worn must be replaced
immediately. The unit, or any part of it should not be
altered without prior written approval of the manufacturer.
ALWAYS insert the cylinder lock when plow is not in
use. If the cylinder lock is not installed, the plow blade
could inadvertently drop and cause serious injury.
ALWAYS shut off the vehicle engine, place the
transmission in Neutral or Park, turn the ignition switch to
the “OFF” position and firmly apply the parking brake of
the vehicle before attaching or detaching the blade from
the vehicle or when making adjustments to the blade.
ALWAYS inspect lift system bolts and pins whenever
attaching or detaching the plow, and before traveling.
Worn or damaged components could result in the plow
dropping to the pavement while driving, causing an
accident.
ALWAYS keep hands and feet clear of blade and A-
Frame when attaching or detaching plow.
NEVER stand between the vehicle and blade or directly
in front of blade when it is being raised, lowered or
angled. Clearance between vehicle and blade decreases
as blade is operated and serious injury or death can
result from blade striking a body or dropping on hands or
feet.
NEVER work on the vehicle without having a fully
serviced fire extinguisher available. A 5 lb or larger CO2
or dry chemical unit specified for gasoline, chemical or
electrical fires, is recommended.
NEVER smoke while working on the vehicle. Gasoline
and battery acid vapors are extremely flammable and
explosive.
NEVER use your hands to search for hydraulic fluid
leaks; escaping fluid under pressure can be invisible and
can penetrate the skin and cause a serious injury! If any
fluid is injected into the skin, see a doctor at once!
Injected fluid MUST BE surgically removed by a doctor
familiar with this type of injury or gangrene may result.
REMEMBER it is the owner’s responsibility for
communicating information on the safe use and
proper maintenance of this machine.

Blade Level Adjustment
The Sno-Way 26V has a Max AdjustTM feature that is set
when the plow is first installed and when initially run each
plowing season. The adjustment mechanism is designed
to make the plow wearstrip scrape evenly on flat surfaces
without leaving a trail of snow near the center or the edge
of the plow. Change in adjustment may be needed due
to wear conditions and when the plow is switched
between vehicles. Adjustments can be performed with a
few turns of a wrench.
Adjustment Procedure
1. Move vehicle to a level flat surface, such as a large
parking lot, or a garage floor.
IMPORTANT: If plow leveling procedure is being
performed on uneven pavement, the plow will be
difficult to level correctly. Also include all ballast
weight with the truck while adjusting the plow. Any
additional weight added to the truck after the plow is
adjusted may require the Max AdjustTM system to be
adjusted again.
2. Loosen jam nut on the tilt adjustment cap screw
located in the center section of the plow trip mechanism.
(See Figure 1-19.)
Figure 1-19
3. Swing wings to the straight position and lower plow to
the ground.
4. Turn Down Pressure ON.
5. Swing wings forward to the scoop position, with blade
on ground
6. If the center wear-strip begins to rise off of the floor,
stop moving the wings forward and turn the tilt
adjustment cap screw out. This will cause the tower to tilt
back and towards the truck.
7. Continue to move the wings forward (scoop position)
until they are free to move forward and backwards to the
straight position.
8. If the center wear-strip begins to rise off of the floor
when the wings are brought back to the V-Position, turn
the tilt adjustment cap screw in, causing the tower to tilt
forward.
9. Once proper adjustment has been attained, tighten
the jam nut on the tilt adjustment cap screw.
IMPORTANT: Adjusting in Down-Pressure is
different than adjusting in Float. If the plow is leveled
while in Down-Pressure (which is what is explained
in the manual here) the wings will tend to be "off the
ground" in scoop, when the Down-Pressure is turned
Off. Be aware of which level you are plowing the
most in, Down-Pressure-Level, or Float-Level.
NOTE: If you set the Plow-Level when in float, the outer
wing edge of the wear strip will wear first when down
pressure is turned on.

Mounting Snow Plow To Vehicle
1. Drive truck into plow, aligning light/lift bar frame with
subframe lugs. Pins should fit inside slots cut into
subframe lugs. (See Figure 1-20.)
Figure 1-20
NOTE: If pins are too high or low to fit into slots on sub-
frame, adjust the plow height after power is connected in
the next step. Plug hand held controller into the plow con-
trol harness if controller is wired. To lower the pins, turn
on down pressure and press down. To raise the pins,
press up.
2. Connect the plow and truck power harness
connectors together.
3. Remove controller from truck cab (and plug into plow
control harness if control is wired).
4. Rotate light/lift bar into position by turning on down
pressure and pressing the lower button. (See Figure 1-
21.)
Figure 1-21
5. Rotate mount handles in to lock pins in place. Put
plow into float position by turning down pressure off. (See
Figure 1-21 and Figure 1-22).
WARNING
The power cable in front of the truck is wired
directly to the battery. The power cable is
always energized, even if the truck is turned off.
Always replace the protective cap after
disconnecting the plow power cable. Allowing
an unprotected plug to contact metal parts of
the truck may cause electrical component
damage. Never use a metal object to clean the
plug contacts.

CAUTION
Many new vehicles are equipped with onboard
circuit sensors designed to display a
dashboard LED when a headlight fails.
Generally, these sensors are activated or
tripped any time the circuit is being called upon
to function while the headlight circuit is
incomplete. This means that if a headlight fails
while the headlight is in operation, the sensor
will trip and the dashboard indicator will light
up. It also means that if a headlamp socket is
left empty—or a faulty lamp is installed—and
the circuit is then activated, the sensor will trip
and the dashboard indicator will light up.
These headlight circuit sensors are often
engineered with pre-designated failure limits.
This means that a sensor may be tripped a
limited number of times. After that limit is
reached the sensor may need to be reset by the
dealer or replaced by the manufacturer.
Sno-Way EIS plow light systems essentially
operate through a planned interruption of the
headlight circuit. When the truck-side
connectors are detached from one another, the
vehicle headlamps are disconnected from the
truck circuits which otherwise power them.
Until those truck-side connectors are attached
to the plow-side light connectors, the truck-
side circuits are open. This means that if the
truck’s onboard sensors are active while the
plow lights are being attached to the truck, the
truck’s sensors may trip.

8. Unplug light harness connectors on truck, and light
connectors on plow, which had been plugged together for
corrosion protection during storage. (See Figure 1-24.)
Figure 1-24
9. Plug plow light connectors into mating connectors on
truck light harness. (See Figure 1-25.)
Figure 1-25
10. If control is wired, plug control inside truck cab and
control harness on plow into truck.
11. Raise, lower and angle plow to make sure no hoses
or wires pinch in the plow mechanism.
CAUTION
To avoid unnecessarily tripping the truck’s
sensor, every time the plow lights are being
attached to the truck circuits or the truck
circuits are being reattached to the vehicle
lights, the truck’s lights should be turned off.
Due to the aforementioned concerns, operators
of vehicles equipped with EIS lights should
make themselves aware of whatever circuit
sensors may be installed on their vehicles.
Operators should further become familiar with
their vehicle manufacturer’s description of how
their truck’s sensors are actuated or tripped.
Finally operators should know whether
predesignated failure limits may be engineered
into their truck’s sensors and what repair or
replacement procedures are recommended
should those limits be reached. Currently, the
vehicle models affected are as follows:
2006 and later-Dodge Dakota and Durango - All
packages.
2006 and later-Dodge 1500, 2500 and 3500- All
packages.
2008 Ford F250-F550 - All packages.

General
• Before operating, perform a thorough visual
inspection of the equipment. Look for fluid leaks,
cracked, bent or broken components, loose nuts,
bolts or attachments and proper fluid levels.
• A clean hydraulic system is essential to long pump
life and proper performance.
• When adding oil to the reservoir, wipe the area
around the filler port clean before removing the
breather cap. Use clean oil and a clean funnel, (DO
NOT use a cloth or rag to strain the oil).
IMPORTANT: Sno-Way supplies type 5606 Sno-Way
Hydraulic Oil with the unit from the factory. If
additional oil is added it must be compatible with
Sno-Way oil. If another type of oil has been used in
the system the same type of oil must be used for
topping off system. Improper hydraulic fluid can
cause operating problems in cold weather.
• Do NOT use synthetic oil.
• Oil must contain an anti-foam additive.
• The operational environment for snow plows is an
extremely harsh and corrosive one.
• Ensure all electrical connections are clean and
tight.
• To prevent rust from forming, clean and repaint
exposed metal surfaces.
• NEVER operate the equipment with the protective
covers or guards removed.
Periodic Inspection
After approximately every 20 hours of operation perform
the following inspections procedures:
1. Inspect the plow assembly including the sub-frame
assembly for any damage or excessive wear. Replace
parts as necessary.
2. Inspect all fasteners (Plow & Truck Mount) to ensure
they are properly tightened. Re-tighten loose fasteners to
the proper torque. Loose fasteners on the Bellcrank,
Power Unit to the Pump Platform and Truck Mount must
have the nylock nuts replaced and tightened while using
Sno-Way thread locker 96115529. (Refer to torque
specification chart in this manual).
3. Apply oil or grease to the wing pivot pin between the
hinge tubes and plates. (See Figure 1-31.)
Figure 1-31
4. Apply a small amount of light oil to the wing cylinder
pivot pins and to pivot pins between the blade assembly,
A-Frame, and spring brackets. (See Figure 1-32.)

ments
IMPORTANT: Incorrectly securing fasteners may
result in incorrect operation, excessive wear, and
early failure of plow components. It may also void
your warranty.
• ALWAYS check to make sure you are using the
correct torque specification for the fastener you are
using.
• DO NOT use any lubricants on the threads of any
fastener unless specifically called for in the
assembly or maintenance story for that component.
• NEVER use liquid locking materials, such as
Locktite™ or Threadmaker™, on any fasteners
unless specifically called for in an assembly or
maintenance story for that component.
Standard Fasteners:
The Torque Specifications Chart on page 34 of this
manual should be used as the guide for fastener torque
requirements for most standard fasteners used on the
plow.
Standard fasteners with special torque requirements will
be noted in assembly or service stories pertaining to the
specific piece of equipment.
Hydraulic Fittings
Hydraulic fittings with lock nuts should be assembled with
at least three full turns of the fitting in the port and then the
lock nut should be tightened to 27 lb-ft.
Hydraulic fittings with 37 degree flare end swivels should
be torqued to 18-20 lb-ft.
Hydraulic Cylinders
To avoid corrosion during storage, coat the exposed
(chrome) portion of the lift and angle cylinders with a light
grease.
Electrical Quick Disconnect Plugs
This plow is equipped with the EIS® (Energy Interruption
SystemTM). Any time the plow is removed from the
vehicle, plug the electrical lighting quick disconnect ends
together to prevent corrosion from forming on terminal
ends.
Fluid Requirements
IMPORTANT: Sno-Way supplies type 5606 Sno-Way
Hydraulic Oil with the unit from the factory. If
additional oil is added it must be compatible with
Sno-Way oil.
It is recommended that the fluid in the hydraulic system be
changed once a season.
Do NOT use synthetic oil.

Plow Shoe Adjustment
This plow is equipped with the ability to utilize four (4) plow
shoes. Two plow shoes are located at the outboard end of
each wing, and two plow shoes are located on the inboard
section of each wing, close to the center tower.
Adjust the plow shoes as follows:
1. Raise plow to full up position.
2. Support blade with a jack.
3. Turn vehicle ignition switch and plow control OFF and
apply emergency brake.
4. Adjust shoe assemblies by removing shoe mounting
lynch pin and adding or subtracting washers on the top or
bottom of the shoe-mounting bracket. (See Figure 1-37.)
Figure 1-37
5. After the disk shoe position is properly adjusted place
remaining washer on the shoe stem - above the disk
shoe mounting bracket and below the retaining lynch pin
- to remove all up and down movement of the disk shoe
in the bracket. Failure to do so will result in excessive
wear of the holes in mounting bracket or bending of the
disk shoe stem.
IMPORTANT: Snap lynch pin ring over so that it
contacts the pin. If ring does not contact lynch pin,
rotate the pin and reverse the direction of the ring. If
the ring does not contact the pin it is not locked and
could fall out.
Trip Spring Adjustment
Check the plow shoe adjustment as follows:
1. Level the tower and wings. (See "Blade Level
Adjustment" on page 9).
2. Check gap on springs with a feeler gauge. The gap
between two or more coils should be .015" (A 3x5
postcard is approximately .015" thick). (See Figure 1-38.)
Figure 1-38
If the gap needs adjustment:
a. Loosen the bottom nut on the spring eye bolt(s).
b. Tighten or loosen the top nut until the correct
tension is reached, by measuring with a feeler
gauge.
c. Tighten the bottom nut(s) on all spring eye bolts.
WARNING
Keep hands and feet clear of wings and center
section when setting blocking and lowering
plow. Moving or falling assemblies could result
in serious injury.
