A REVOLUTION AGAINST SNOW
Congratulations on purchasing the finest snowplow made. BOSS sets the standard for quality, reliability,
craftsmanship, and performance. Our products are designed, built, and proven in Michigan’s rugged Upper
Peninsula, where winter is a way of life. And we back it all up with exceptional customer service and
satisfaction. We’re not just setting the standard. We’re leading the way.
BOSS SNOWPLOW has been carefully designed and built for years of carefree performance. With its
simple attaching system, BOSS can be attached or removed in seconds. For safety, BOSS includes
hydraulic pressure relief to prevent damage by overstress. Where A-Frame and moldboard fatigue are a
common problem on conventional plows, a BOSS PLOW will stand up to severe plowing conditions.
To keep your BOSS PLOW in top shape, take a few minutes to study this manual. It will show you how to
use and service BOSS, familiarize you with all of its parts, and give you helpful tips on plowing snow.
If you have further questions, your local BOSS PLOW DEALER is the person to talk to. They know your
plow well and want your complete satisfaction.

Serious injury or death can result if you do not follow these instructions and procedures which are
outlined further within your owner’s manual
Read this manual carefully before operating this snowplow.
Always follow the vehicle manufacturer’s recommendations relating to snowplow installation.
For recommended vehicle models refer to the BOSS online Plow Selector tool at
www.bossplow.com.
Vehicles equipped with air bags are designed such that the air bags will be activated in a
frontal collision equivalent to hitting a solid barrier (such as a wall) at approximately 14 mph or
more, or, roughly speaking, a frontal perpendicular collision with a parked car or truck of
similar size at approximately 28 mph or more. Careless or high speed driving while plowing
snow, which results in vehicle decelerations equivalent to or greater than the air bag
deployment threshold described above, would deploy the air bag.
Many newer trucks are equipped with air bags. DO NOT under any circumstances disable or
remove or relocate any sensors or other components related to the operation of the air bags.
When transporting, position plow so as not to block vision or plow headlights.

7
DO NOT change blade position when traveling.
DO NOT exceed 40 mph when transporting plow.
DO NOT exceed 14 mph when plowing.
Always lower blade when vehicle is not in use.
Make sure plow is properly attached before moving vehicle.
To comply with Federal Regulations and to assure a safe vehicle, the Front Gross Axle Weight
Rating (FGAWR), Rear Gross Axle Weight Rating (RGAWR), and the Gross Vehicle Weight
Rating (GAWR) must not be exceeded at any time.
Due to the variety of equipment that can be installed on this vehicle, it is necessary to verify
that the Front Gross Axle Weight Rating (FGAWR), Rear Gross Axle Weight Rating (RGAWR),
and the Gross Vehicle Weight Rating (GAWR) are not exceeded at any time. This may require
weighing the vehicle and adding ballast as necessary. It may also limit payload capacity of the
vehicle. It is the operator’s responsibility to verify that these ratings are not exceeded.

Your BOSS PLOW is designed for heavy-duty, rugged service with minimal maintenance. To ensure that it
gives you the same high performance year after year, please use it properly and observe the following
maintenance precautions.
Inspect the following on a regular basis:
1. All fasteners, pins, retainers, nuts and bolts for tightness. See Recommended Bolt Torque located in this manual.
2. All hydraulic lines and connections for wear and leakage.
3. Hydraulic cylinders for leakage, rods for rust or pitting.
4. Cutting edge wear.
5. Plow shoe wear (If installed).
6. Hydraulic oil level (CAUTION: DO NOT OVERFILL). Fill using BOSS Snowplow High Performance
Hydraulic Fluid or equivalent. See Hydraulic Power Unit Fill Procedure located in this manual.
7. Control Harness and Power/Ground Cable Connectors for corrosion. Apply dielectric grease at least
once a month during the plow season.
8. Apply grease to coupler spring pins.
