228STARTING AND OPERATING
BEFORE PLOWING
Check the hydraulic system for leaks and
proper fluid level.
Check the mounting bolts and nuts for proper
tightness.
Check the runners and cutting edge for
excessive wear. The cutting edge should be
¼ to ½ inches (6 cm to 1.2 cm) above ground
in snow plowing position.
Check that snowplow lighting is connected
and functioning properly.
SNOWPLOW PREP PACKAGE MODEL
A
VAILABILITY
For Information about snowplow applications
visit www.ramtrucks.com or refer to the current
Body Builders Guide.

1. The maximum number of occupants in the
truck should not exceed two.

2. The total GVWR, Front GAWR or the Rear GAWR should never be exceeded.
3. Cargo capacity will be reduced by the addition of options or passengers, etc.
The loaded vehicle weight, including the
snowplow system, all aftermarket accessories,
driver, passengers, options, and cargo, must
not exceed either the Gross Vehicle Weight
(GVWR) or Gross Axle Weight (GAWR) ratings.
These weights are specified on the Safety
Compliance Certification Label on the driver's
side door opening. NOTE:
Detach the snowplow when transporting
passengers.
Vehicle front end wheel alignment was set to
specifications at the factory without
consideration for the weight of the plow. Front
end toe-in should be checked and reset if
necessary at the beginning and end of the
snowplow season. This will help prevent uneven
tire wear.
The blade should be lowered whenever the
vehicle is parked.
Maintain and operate your vehicle and
snowplow equipment following the
recommendations provided by the specific
snowplow manufacturer.
WARNING!
Attaching a snowplow to this vehicle could
adversely affect performance of the airbag
system in a collision. Do not expect that the
airbag will perform as described earlier in this
manual.
CAUTION!
The “Lamp Out” indicator could illuminate if
exterior lamps are not properly installed.
