NOTE: The blade skin must be retained prior to removing
the wing cutting edges. This can be accomplished by
using a 6" c-clamp located at the center of the curved
portion of the blade skin at the outer end of the wing.
5. Remove the mounting bolts holding the old wing cut-
ting edges to the blade wings. Discard old cutting edges
and hardware.
6. Install new wing cutting edges using new hardware.
7. Install new center cutting edge and secure with new
mounting strip and new hardware. Torque the three cen-
ter cutting edge fasteners to 50 lb.-ft.
Trip Spring Adjustment
NOTE: The trip springs are factory installed and
adjusted, but adjustment should be checked during plow
set-up and installation.
The springs are properly adjusted when the coils begin to
separate.
If readjustment is required:
1. Raise the plow to transport position and place
blocking under the plow to prevent the plow from
inadvertently dropping.
2. Turn off the vehicle ignition, apply the parking brake
and remove the vehicle ignition key. Turn hand-held con-
troller off.
3. Check to make sure that the spring is installed as
illustrated with open end of top loop facing vehicle. (See
Figure 2-9)
4. Using a 15/16" socket wrench through the holes in
the bottom plate of the main frame, loosen the two (2)
5/8" nuts on the trip spring eyebolts. (See Figure 2-9)
5. After the two lower nuts have been loosened, the two
upper nuts can be rotated on the eye bolts to allow the
trip springs to be shortened or lengthened.
6. While holding the two upper nuts, re-tighten the two
lower nuts and then re-check the spring adjustment.
NOTE: Springs are properly adjusted when two or more
coils allow a 0.010" feeler gauge to just pass between the
separated coils. (A 3 x 5 post card is approximately the
same thickness.)

CAUTION
• Do not overtighten springs. If more than 0.015"
(1/64") gap appears between coil with plow at
rest damage could occur to equipment during
plowing.
• Spring must be installed with open end of top
loop facing vehicle. Bottom loop position will
vary.
