WARN INDUSTRIES * BASIC GUIDE TO PLOWING

BEFORE YOU PLOW
Setting Spring Tension
The spring brackets on the
WARN plow have two specifically
designed positions. The stiff
setting will position the bracket in a
lower position with the end of
spring closer to vehicle. The softer
setting will position the bracket
more upright.
The stiff setting will produce
the highest blade rollover force.
Using the stiff spring position with
the most aggressive (forward)
blade attack angle position will
produce the highest scraping
action, useful for gravel driveway
maintenance or plowing ice and
snow clean.
The softer spring setting will
lower the blade rollover force and
should be used with lighter
vehicles and typically the most
aggressive (forward) blade attack
angle.
Both spring brackets on the
plow base will need to be rotated
and set to the same position. Use
a 17mm wrench to loosen the
lower M10 lock nut securing each
bracket. Use a 17mm wrench to
remove the M10 lock nut and
carriage bolt near the top of the
bracket. Insert a 3/8" drive ratchet
or breaker bar into a square
bracket hole that will not be used
for the bolt. Press the bracket
down to align the holes in bracket
and base. Secure each bracket
with a M10 carriage bolt and lock
nut. Torque all M10 nuts to 42 N-
m (31 ft-lbs).
Never remove the
springs and hard
fixture the blade to
the plow base or
vehicle. Doing so
will prevent the
plow from tripping
(rollover) during an
impact with a low-
lying object and
possibly damage
the plow, vehicle, or
eject the rider from
the vehicle causing
serious injury or
death.
Loosen M10 lock nut and carriage bolt
securing brackets.
Remove M10 nut and carriage bolt.
Press bracket down to align holes in
bracket and base.
Secure each bracket with M10 carriage
bolt and lock nut.
