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 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 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 check your local laws with regards to
transporting plow mounted on vehicle on public roads.
NEVER change blade position while traveling.
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 injury.
ALWAYS shut off the vehicle engine, place the
transmission in Neutral or Park, turn the ignition switch to
the “OFF” position, firmly apply the parking brake of the
vehicle and turn “OFF” the plow controller 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 place fingers in A-frame or mount lug holes to
check alignment when attaching snow plow. Sudden
motion of the plow could severely injure a finger.
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 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 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.

General
• Before operating, perform a through 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 system is essential to long pump life and
proper performance.
• When adding oil to the reservoir, wipe 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 the system. Improper hydraulic fluid can
cause operating problems in cold weather.
• Do NOT use synthetic oil.
• Oil must contain an anti-foam additive.
• 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.
Break In Period
The plow will go through a break in period during which
the A-frame and swing frame will settle in. After 15-20
hours of operation check for free play of the A-frame and
swing frame pivot.
1. Raise the plow and insert a jack stand under the A-
frame.
2. Push down on end of blade as far as it will go on the
right or left side. Measure and record the distance from
the ground to the bottom edge of the wear strip.
3. Pull upwards on the same end of the plow as far as it
will go. Measure and record the distance from the ground
to the bottom edge of the wear strip.
4. Subtract the two measurements. If the number is
greater than 1-1/2" then the free play needs to be
adjusted.
To Remove Excessive Free Play
1. Tighten the pivot bolt nut (typically 1/6 to 1/3 turn, one
or two flats).
Periodic Inspection
After every 20 hours of operation perform the following
inspections:
1. Inspect plow assembly including sub frame for any
damage or excessive wear. Replace parts as necessary.
2. Inspect all fasteners (Plow & Truck Mount) to insure
they are properly tightened. Re-tighten loose fasteners to
the proper torque. Loose fasteners on the Bellcrank,
Pump Platform to A-Frame, Power Unit to the Pump
Platform, and Truck Mount must have the locknuts
replaced and tightened while using Sno-Way thread
locker 96115529. (Refer to torque specification chart in
this manual).
3. Apply a small amount of light oil to: Quick-tatch pin
and handle assemblies, pivot pins between the blade and
swing frame, and pivot pins at lift and swing cylinders.
Also lubricate jackstand pins. (See Figure 2-1)
Figure 2-1
WARNING
Before servicing plow, lower plow to the
ground or onto cylinder lock clamp and
disconnect main power harness.

Plow Storage
When storing the plow for long periods of time use the
following guidelines.
1. If the plow will not be stored on pavement, place a
board under the jack stand to prevent it from sinking into
the ground.
2. To prevent corrosion, coat the exposed portion of the
cylinders with light grease.
3. Grease all pivot points.
4. Fill hydraulic reservoir to the fill line to minimize
trapped air.
5. Place dielectric grease on the terminals of all
electrical plugs, including those under pump cover. Make
sure protective caps are in place or connectors are
plugged together.
6. Check and replace any worn or damaged
components, such as cutting edges, deflectors, and
bushings.
7. For additional protection, use a 99101213 plow parka
cover.
Polycarbonate Blade Care
• DO NOT use abrasive or highly alkaline cleaners on
polycarbonate blade.
• Never scrape polycarbonate blade with squeegees,
razor blades or other sharp instruments.
• Benzene, gasoline, acetone or carbon tetrachloride
should never be used on polycarbonate blade.
• DO NOT clean polycarbonate blade in hot sun or at
elevated temperatures.
Polycarbonate Blade Cleaning
Instructions
Wash with a mild soap or detergent and luke-warm water
using a clean cloth or soft sponge. Dry thoroughly with a
chamois or moist cellulose sponge to prevent water spots.
Special Fasteners Torques and
Requirements
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.
Standard Fasteners
The Torque Specifications Chart on page 27 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 instructions pertaining to
the specific piece of equipment.

Hydraulic fittings with locknuts should be assembled with
at least three full turns of the fitting in the port and then the
locknut should be tightened to 27 lb-ft.
Hydraulic fittings with 37 degree flare end swivels should
be torqued to 18-20 lb-ft.
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.
NOTE: Type 5606 oil is rated to -60 deg. F, when Type
5606 is not available Exxon UNIVIS J13 or equivalent
may be used.
Do NOT use synthetic oil.
Oil must contain an anti-foam additive.
NOTICE
• Using the proper oil increases the life
expectancy of the most critical part of your
plow; the hydraulic power unit.
• Failure to use the proper oil can cause
extensive damage to the power unit, seals and
hydraulic cylinders.
• Improper oil can cause operating problems and
poor performance in cold weather.
FAILURE TO FOLLOW COULD LEAD TO
PROPERTY DAMAGE.

Operating Class
The 22 Series 2 Sno-Way plow is specifically designed for
applications on light duty trucks and SUVs.
NOTE: The loaded vehicle, including any ballast weight
and optional equipment, must not exceed the Gross
Vehicle Weight (GVW) or front or rear Gross Axle Weight
(GAW) ratings specified on the Safety Compliance Certi-
fication Label located on the driver's side door opening.
For additional information, refer to your dealer and the
Sno-Way Application Guide for proper vehicle applica-
tions.
Before the Season Begins
1. Inspect plow vehicle’s electrical system for proper
operation.
2. Inspect plow assembly including sub frame for any
damage or excessive wear. Replace parts as necessary.
3. Inspect all fasteners to insure they are properly
tightened. Re-tighten loose fasteners to the proper torque
(Refer to torque specification chart in this manual).
4. Apply a small amount of light oil to: Quick-tatch pin
and handle assemblies, pivot pins between the blade and
swing frame, and pivot pins at lift and swing cylinders.
Also lubricate jackstand pins. (See Figure 2-1).
5. Clean and repaint any exposed metal parts with
corrosion resistant enamel.
6. Check free play between the a-frame and swing
frame pivot. Adjust if necessary. (See "Break In Period"
on page 10).
7. Check the oil level and repair any oil leaks. (See
"MAINTENANCE" on page 10).
8. Inspect electrical connectors. Make sure the contacts
are clean, and apply a small amount of dielectric grease.
9. If ballast is required, position and secure ballast
behind rear wheels, for optimum performance.
Transporting Vehicle With Plow Attached
1. Always install the cylinder lock clamp when the plow
is raised and the operator is not engaged in plowing
operations. See "Installing The Cylinder Lock Clamp" on
page 8.
2. Position the blade out of the beam path of the
headlights before driving.
3. Do not exceed 45 M.P.H. when driving with the
snowplow attached. Braking distance is increased and
handling impaired at speeds above 45 M.P.H.
4. Reduce speed when crossing railroad tracks or when
road conditions deteriorate.
5. Never change blade angle or height while driving.
6. Inspect plow and attaching hardware for damage
before transporting or plowing.
Plowing Like A Pro
NOTICE
• Remove the plow when driving extended
distances at temperatures above 40 deg. F, the
plow blocks enough airflow to cause it to overheat
at temperatures above 40 deg. F.
FAILURE TO FOLLOW COULD LEAD TO
PROPERTY DAMAGE.
WARNING
Check your local laws with regards to
transporting plow mounted to vehicle on public
roads.
FAILURE TO FOLLOW CAN RESULT IN DEATH
OR SERIOUS INJURY.
WARNING
Wear your seat belt! Contact with a hidden
obstruction can cause serious personal injury
from bodily contact within the vehicle cab or
whiplash from sudden stops.
FAILURE TO FOLLOW CAN RESULT IN DEATH
OR SERIOUS INJURY.
WARNING
• Never exceed 10 m.p.h. when plowing! Serious
personal injury can result, as well as damage
to equipment and property, if an unseen
obstruction is encountered while plowing.
• Never plow with your head protruding from the
vehicle side window. Serious head or neck
injuries can result from sudden stops or
coming into contact with tree branches, signs
or other stationary objects.
FAILURE TO FOLLOW CAN RESULT IN DEATH
OR SERIOUS INJURY.
PLOWING OPERATION

16
NOTE: The air bag is factory set to deploy at a certain
acceleration level. The air bag will deploy with the plow
attached if an obstruction is hit with enough force to
reach this level. Always plow within the recommended
plowing speeds and know the area you are plowing to
avoid any obstructions.
NOTE: For better clean up of hard packed snow; raise
the plow shoes so that the cutting edge of the blade
comes into direct contact with pavement. Use the lowest
possible gear to place maximum power behind the cut-
ting edge.
For instructions on using the plow controller to manipulate
the plow see the manual included with your plow control
package.
1. Become familiar with the area to be plowed and mark
potential hazards before the snow falls. Many immovable
objects cannot be seen when covered with snow.
Developing a plan early can save valuable time and
equipment damage. Allow sufficient room to pile snow,
out of the traffic area, with enough space for when the
next storm comes.
2. Plow with the storm. The "Pros" are out early
removing only several inches at a time. Allowing snow to
accumulate to unmanageable levels can cause removal
problems and wear and tear on equipment. The plow is
not a "Ram" or a "Bulldozer". If used properly, it will give
many years of safe and reliable service.
3. Research municipal ordinances for restrictions on the
disposal of snow. Many municipalities do not allow snow
to be placed in or moved across roads or highways.
4. Research state department of transportation rules on
maximum width restrictions for snow plows. Certain
blades may require permits.
Using The Down Pressure (DP) Hydraulic
Systems
The DP system was designed for removing hard packed
snow from hard surfaces that has been driven on prior to
plowing.
The system should be turned OFF when plowing surfaces
such as gravel, dirt, sand, etc., to prevent cutting into the
surface.
Activating the system applies down pressure to the down
pressure side of the lift cylinder. This down pressure will
force the cutting edge through hard packed snow. If down
pressure decreases as a result of a low spot, more down
pressure will be applied to the lift cylinder. When a high
spot is encountered the down pressure will be relieved to
allow the plow to follow the contour without lifting the front
of the truck.
Clearing Driveways
1. Head into driveway with the blade angled to move
snow away from buildings. Continue to widen the drive
path by rolling snow away from buildings on successive
passes.
2. If there is a garage at the end of the driveway, plow to
within several vehicle lengths of the garage and push the
snow off the driveway.
3. Raise the blade and drive through the snow up to the
garage. Drop the blade and "Back Drag" the snow 1-1/2
vehicle lengths back. Repeat as necessary.
4. Back the vehicle to garage door and plow forward
toward street, removing the remaining snow.
NOTICE
Excessive stacking of snow causes undo
stress to the snowplow and vehicle. Repeated
loading of this nature may result in the failure
of plow components designed to protect the
snowplow and vehicle from major damage.
FAILURE TO FOLLOW COULD LEAD TO
PROPERTY DAMAGE.

Introduction
Whenever service is necessary, your local dealer knows
your plow best and is interested in your complete
satisfaction. Return your snowplow to your local dealer for
maintenance service or any other assistance you may
require. If you are unable to do so, this troubleshooting
guide should help you determine the problem. However,
before attempting the servicing of your plow, you should
possess good mechanical abilities and a total
understanding of the mechanism.
PLEASE: Before calling parts and service personnel be
certain that:
1. You have read this guide carefully and are certain
that all of the suggestions pertaining to your problem
have been attempted.
2. You have the following available:
A. Date snowplow was originally installed
