(57), and 5/16”-18 hex nuts (59). Note: Light brackets may be adjusted down two
levels in height for better appearance on lower prole vehicles. Tighten all fasteners
to their proper torque.

D. Attach Eye Bolts (55) to Moldboard and Trip Springs (36) to Pivot Bar (6), making
certain locknuts are positioned as shown below.
E. Make certain each Eye Bolt (55) is in a vertical position as shown below so that the
Eye Bolt (55) and Trip Spring (36) hinge properly when moldboard trips.
Note: Proper tension is attained when Trip Spring (36) coils just begin to separate
and then tightening top locknut four additional turns. Tighten bottom Locknut (20530)
to secure Eyebolt in position. Install Eyebolt caps (07031) over exposed threads.
F. Attach Plow Markers (43) to moldboard using 5/16-18 x
1” Bolt (44), 5/16” Flatwasher (46) and 5/16-18 Locknut (45)
(5)
G. Attach the Lift Chain to the Lift Arm (14) through the two hooks on the lift arm. Adjust
the lift chain at the lift arm so that there are 2-3 links of slack. This ensures that the
plow blade will lift fully and be able to follow the ground contour while plowing.

K. Meyer M-1 Hydraulic Fluid Part No. 15134 may need to be added to reservoir and
bleed the Angle Cylinders, proceed as follows:
a. Remove Fill Plug from reservoir to add uid during charging.
b. Operate the Angle cylinders (2) until they are lled with Meyer M-1 Hydraulic Fluid
and are not spongy.
c. Top off the unit to the ll line on the reservoir with Meyer M-1 Hydraulic Fluid.
NOTE: Proper uid level is to the ll line on the reservoir for the E-72 or
1” below the ll plug on the E-58H . It must be checked with the lift
cylinder fully retracted.

H. Run Universal Truck Side Harness (54) through a hole in grille and into the engine
compartment. Sandwich vehicle grill between Plug Bracket (37) and Plate (38) using
Bolt H 5/16-18 x 3” (42), 5/16 Lockwasher (40) and 5/16-18 Finish nut (41). Secure
Universal Truck Side Harness (54) to Plug Bracket (37) using Bolt H 5/16-18 x 1” (39),
5/16 Lockwasher (40) and 5/16-18 Finish nut (41).
Secure Universal Truck Side Harness (54) from any hot /
moving parts with tie wraps as needed.
I. Drill a 1-1/4” Diameter Hole thru rewall to install split bushing (52) and extend the
harness into the cab of the vehicle. Fused lead from Universal Truck Side Harness (54)
must be attached to terminal in fuse panel that is activated only when the ignition key
is “on.”
J. Install Motor Solenoid (50) to metal surface in engine compartment using Self Tapping
Screws (51). (Solenoid must be grounded to operate). Attach Red Power Cable (54) to
a large terminal on Motor Solenoid (50). Attach Black Ground Cable (54) to negative
(-) terminal of battery. Attach Red Power Cable (35) to positive (+) terminal of battery
and remaining large terminal on Motor Solenoid (50). Attach small white wire from
harness (54) to small terminal (S) on Motor Solenoid (50). Attach small Black/white
stripe wire from harness (54) to small terminal (I)(ground) on Motor Solenoid (50) At
tach Blue wire to a reverse signal on the vehicle. The blue wire is sensing when the
vehicle is in reverse in order to operate HFP (Hands Free Plowing).

Vehicle Side Wiring Diagram

For snow plow light installation see separate instructions.
Orange wire on Harness (54) will attach to both orange wires of the “B” harness
supplied in the Light Module Kit. Reference Form 1-757
Route Cables “C” (Yellow) from module to Harness (54). Connect both “C” Harness
female ends to the male corresponding ends of the Harness (54).
Connect both male ends from the snow plow light to the female ends on the
Plow Side Harness (32).
Check snow plow light blinkers to make sure the wires have not been reversed.
Note: All electrical connections should have both ends coated with a dielectric grease,
Meyer Part No. 15632, prior to nal installation. This will ensure a good connection
and help in preventing corrosion.
L. Refer to Operation and Maintenance Manual for complete controller operation.
M. After all electrical connections have been made the drop speed of the plow may be
evaluated / adjusted. To adjust, loosen the hex nut and adjust in to slow the drop
speed and out to make it faster. After ideal drop speed it achieved, retighten the hex
nut. See below.
After cycling of the plow, recheck oil level.
E-58H Lower Adjustment (left side of vehicle):
Loosen jam nut and turn screw clockwise to slow the drop of the plow and counter
clockwise to speed the drop of the plow. Tighten jam nut.
E-72 Lower Adjustment (left side of hydraulic unit):
Loosen jam nut and turn knob clockwise to slow the drop of the plow and counter
clockwise to speed the drop of the plow. Tighten jam nut.
(7)
N. Assemble adjustable stacking stop bolts to lift frame (12) using
5/8-11 x 3” bolts (63), lockwasher (25) and jamnuts (64). See below.
Note: Adjustment must be made after moldboard assembly is installed. Adjustment
bolts (63) should make contact with the a-frame before any part of the A-Frame/
Sector or moldboard come in contact with the lift arm and, or hydraulic unit while
raising the snowplow or stacking snow. Moldboard should be checked in all positions.

Meyer Products assumes no responsibility for installations not
made in accordance with these instructions.
A. Pull vehicle into plow assembly
and push plow assembly forward an
inch or two.
F. Attach crankstand to lift frame.
E. Remove crankstand from
a-frame.
D. Adjust crankstand until it is no
longer in contact with the ground.
C. Push back on lift frame until
both pins spring thru mount
on vehicle.
B. Twist handles on both sides to
engage spring loaded pins.
G. Remove weather cover on male end and connect one piece electrical plug. The spring
loaded cover will lock one piece plug.
