TRP07882-16
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.

Many newer trucks are equipped with air bags. DO NOT under any circumstances disable, remove
or relocate any sensors or other components related to the operation of the air bags.

Always follow the vehicle manufacturer’s recommendations relating to snowplow installation. For
recommended vehicle models refer to the BOSS Snowplow Application Chart and Selection Guide.

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.

When transporting, position plow so as not to reduce visibility or block plow headlights.

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.

Never place any part of your body under the snowplow at any time. Doing so may cause bodily
harm and/or death.

Wear proper personal protection equipment when operating and servicing snowplow; including, but
not limited to, clothing for cold weather and slippery surfaces.

Refer to vehicle manufacturer’s Owner’s Manual for proper driving and parking procedures
including any specific procedures that related to snowplows.

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.

Some snowplow components are very heavy – use properly rigged 1/2-ton minimum lifting device
to maneuver heavy snowplow components.

Snowplow operating noise level below 70dB.

MSDS are available at www.bossplow.com.

Hydraulic component installation and maintenance must be performed by trained personnel.

Never place body parts between snowplow and vehicle.

When transporting be sure to properly secure your load. Proper load securing instructions are
available at www.bossplow.com.

Figure 35. Oil Full Level
G10411
Plow Position to Check Oil: The plow should be
attached to the truck, sitting flat on the ground, with
the blade in the straight position.
6. With the blade in the straight position and the
plow lowered to the ground, check the fluid level.
Fluid should be visible in the external fill port. If
fluid is not visible, fill until visible. Your reservoir
should now be properly filled.
Figure 34. External Fill – Backside View
Note: Hydraulic fluid should be replaced annually
with BOSS Snowplow High Performance Hydraulic
Fluid.
G10124
Note: If your plow is equipped with SmartHitch2™
you must hydraulically power the light tower down. Do
not manually pull the light tower down. Failure to
hydraulically power the light tower down will create an
air pocket in the hydraulic system. Oil will spill out of
your internal filler cap.
Step 1 of the following fill procedure is intended for a
new plow with an empty hydraulic system.
Initial Plow Position: Start with the plow unattached
from the vehicle and the lift cylinder completely
collapsed. The light tower will be tilted forward.
1. Remove Fill Cap (20F) from Street Elbow (20G)
and fill with BOSS High Performance Hydraulic
Fluid. Continue to fill Street Elbow (20G) until no
more fluid will be accepted. (Approx. 2 quarts.)
When adjusting Flow Control Valve (31C) make sure
all appendages are clear of the plow blade and
observers are standing a safe distance away from the
plow blade. The plow may drop if your controller is in
the FLOAT position. Make sure your controller is in
the OFF position before attempting to adjust the plow.
Failure to follow this warning could result in bodily
harm.
2. Attach the plow to the vehicle.
Note: If your plow is equipped with SmartHitch2™
you must hydraulically power the light tower up. Do
not manually push the tower up. Failure to
hydraulically power the light tower up will create an air
pocket in the hydraulic system. Oil will spill out of your
internal filler cap.
Note: Flow Control Valve (31C) is not available on
Green colored Hydraulic Manifolds used on Standard
Duty and Sport Duty snowplows.
3. Raise the plow.
4. With the plow in the raised position, cycle through
both angle functions several times.
5. Lower the plow to the ground.
7. Adjust Flow Control Valve (30D) to obtain the
speed desired for lowering the plow by loosening
the jam nut, then adjusting the set screw.
Counter-clockwise adjustment will increase the
speed the plow descends. Retighten the jam nut
when the desired speed is obtained.
Note: If your plow will not lower, Flow Control Valve
(30D) is completely closed. Refer to Step 7 to adjust
Flow Control Valve (30D).

Automotive engineers (SAE) pertinent to headlight
aiming. These points can be found in publication
#SAEJ5991D.
Figure 30. Headlight Aiming Procedure
G10153
6. The correct visual aim for Type 2 headlights is
with the top edge of the high intensity zone of the
lower beam below the horizontal centerline and
the left edge of the high intensity zone on the
vertical centerline. See diagram above.
Preparation for Headlight Aim or Inspection
Before checking beam aim, the inspector shall:
 Remove ice or mud from under fenders.
 See that no tire is noticeably deflated.
 Check vehicle springs for sag or broken
leaves.
 See that there is no load in the vehicle other
than the driver.
 Check functioning of any “level-ride” controls.
 Clean lenses and aiming pads.
 Check for bulb burnout, broken mechanical
aiming pads, and proper beam switching.
 Stabilize suspension by rocking vehicle
sideways.
