OPERATION and MAINTENANCE MANUAL
Insist on genuine Meyer Parts & Accessories

Snow, despite the beauty it may impart to a bleak winter landscape,
poses the dual threat of inconvenience and danger. The environmental
conditions associated with snow, not to mention the health hazards and
economic loss it may impose, seriously endanger thousands of lives
annually. Business and industry suffer, and millions of snowbelt residents
may be affected by a single snowstorm.
Meyer Products Inc. has published this manual to help you get the
maximum performance from your Meyer Snow Plow and familiarize you
with the features designed for efficiency and safety; be sure you recognize
and understand them. Follow recommended operation and maintenance
instructions, so when a storm hits, your Meyer Snow Plow will be ready
and you will know how to plow like a pro. DO NOT EQUIP ANY VEHICLE
WITH A SNOW PLOW WITHOUT CONSULTING MANUFACTURERS’
RECOMMENDATIONS.
Vehicles with Meyer Snow Plows installed may be so equipped as to
meet vehicle manufacturers’ specifications and recommended options
for snow plowing use. Most vehicle manufacturers insist that vehicles
which are to be used for snow plowing be equipped with certain
options and accessories, and it is so stated in vehicle manufacturer
specifications for snow plow application.
Warning: Deployment of an air bag while using a Meyer snow plow
will not be covered under Meyer Products’ warranty.
We also recommended that, for optimum performance, vehicles used
for snow plowing be equipped with:
• Four Wheel Drive
• Minimum 60 Amp Alternator or Larger
• Minimum 70 Battery of Larger (550 C.C.A.)
• Mud and Snow Tires
• Increased Radiator Cooling
• Automatic Transmission
• Power Brakes
• Power Steering
Under the continuing Meyer Products Improvement Plan, Meyer Products
Inc. reserves the right to change design details and construction without
prior notice and without incurring any obligation.
IMPORTANT NOTICE: In conjunction with FMVSS (Federal Motor Vehicle Standard) and OEM (Original Equipment Manufacturer) guide lines, Meyer Products LLC
has designed this plow package with the following guidelines:
CAUTION: Installation of a snowplow may affect your vehicle warranty. For more information consult your Vehicle Owners’ Manual / Vehicle Dealer.
WARNING: The vehicle must not be operated when overloaded. In all cases, the loaded vehicle weight, including th entire snowplow system, all aftermarket acces-
sories, driver, passenger, options, nominal fluid levels, and cargo must not exeed the front/rear Gross Axle Weight Rating (GAWR), and total Gross Vehicle Weight
Rating (GVWR). These weight ratings are specified on the safetay compliance certification label on the driver’s side door opening. The use of rear ballast weight
may be required to prevent exceeding the front GAWR.
WARNING: Check your local/state/provincial laws regarding vehicle restrictions when the snowplow is not attached. These restrictions during specified times of
the year may require the removal of the mounting, lift frame, lift arm, hydraulic mechanism or any other fixtures or protruding surfaces mounted to the front of the
vehicle.

SNOWPLOW HAND HELD
CONTROLLER OPERATION
To turn the controller on, press the on button located in the upper
right hand corner on controller.
The snowplow should only be in operation when the vehicle
ignition switch and the hand held controller are in the “ON”
position. Care should be taken to insure that the hand held
controller is kept dry and free from moisture during normal
operation.
When the hand held controller is turned “On,” lights illuminate
all buttons.
Lowering of the snowplow an inch at a time is possible by
tapping the down arrow in short intervals. Holding down the
down arrow for 1 second will activate a float light to the left of
the on/off button. This light indicates the snowplow is now in the
Lower/Float position. In this position the snowplow will be able
to follow the contour of the road and the snowplow can also be
angled to the left or right. Touching the up arrow automatically
cancels the Lower/Float position.
Note: To regulate the lower speed, locate the Lower Adj. Screw
on side of angling block. Loosen locking Nut Screw in to slow
down or out for faster lower speed. See form 1-878 (E-68) for
more details.

Up
Left
Down
While angling left or right or raising the snowplow if the button
is pressed for more than four seconds the operation will be
cancelled. This feature eliminates unnecessary amp draw from
the vehicle charging system.
The auto lower (ALM) button when pressed will illuminate the light
above it and allows the plow to lower automatically when the
vehicle is shifted into reverse and raise automatically when shifted
out of reverse. To turn off the auto lower mode simply press the
auto lower button again and the ALM light will go out.

-6-
The Shake (SHK) button when pressed will shake the plow left
and right for three seconds. This function is used to shake off
any snow which may be stuck to the plow. This function is only
available within the last ten seconds of an angle, raise or lower
operation.
Using the “Mount” button
The Mount (MNT) button when pressed will turn on the
Mount/Dismount Mode. In this mode the Mount/Dismount
Switch on the hydraulic unit is activated and no other snow
plow functions will be available. To confirm that the Mount/
Dismount switch is in the Mount/Dismount Mode all controller
buttons will illuminate and flash. The buttons on the controller
will continue to flash until the Mount (MNT) button is pressed
again turning the Mount/Dismount mode off.
Activation of the Mount/Dismount Switch for longer than
15 seconds at a time will shut down the Mount/Dismount
operation. Release of the toggle switch momentarily will allow
activation to continue. This is an enhanced feature used in the
Hand Held Controller for all snowplow functions. This feature
eliminates unnecessary amp draw from the vehicle charging
system when operating the snow plow.
Monitor Light
The Hand Held Controller is intelligent and will assist in
diagnosing electrical problems. The Hand Held Controller
continually monitors the snow plow system during plow
operation. When the Hand Held Controller recognizes a
potential problem the Monitor Light will begin to flash. The
Monitor Light is located in the upper left hand corner of the
controller next to the Float indicator light.
Counting the number of flashes and using the diagnostic
chart located on the back of the controller will help locate the
component part that is causing the malfunction. See chart
below.
See page 11-13 for more trouble shooting information.
The Hand Held Controller can be reset by the controller being
turned off momentarily and then back on again.
Note: If Monitor light is still illuminated after attempts to reset
the controller, please contact your nearest authorized Meyer
Distributor for repairs.

4. Press Mount (MNT) button on Hand Held Controller. All controller buttons will illuminate and flash.
5. Activate system using the Mount/Dismount Switch in the direction that lowers the plow stand. Note: The Mount/Dismount
Toggle Switch is located on the back side of the hydraulic unit (Figure 2). Continue lowering the plow stand until contact with
ground is made and the hook assembly is raised up and off the Lift Frame. Note: While toggle switch is activated to keep
assembly vertical, it will be necessary to use your other hand to lower the Lift Arm (completely) while at the same time the hook
assembly is raising. See Figure 3.
6. It is also recommended that the Mount/Dismount cylinder be completely collapsed and the Xpress Lock Pin installed when
system is removed from the vehicle to help prevent theft.
7. Disconnect Main Harness from Lift Frame. See Figure 4.
IMPORTANT: When Xpress TM system is removed from the vehicle, the Hand Held controller must remain
“OFF” for proper operation of the OEM light system.
Mounting Xpress™ Assembly :
1. Drive your vehicle up to the Xpress TM System until Lift Frame makes slight contact with Hook Assembly.
2. Plug in Plow Side Harness into Vehicle Side Harness on Lift Frame making sure the harnesses lock together. See Figure 4
3. Turn on vehicle ignition switch, then Hand Held Controller.
4. Press Mount (MNT) button on Hand Held Controller. All controller buttons will illuminate and flash.
5. Activate system using the Mount/Dismount Switch in the direction that lowers the Hook Assembly onto the Lift
Frame and raises the plow stand up to clamp and lock onto the bottom of the Lift Frame. Note: The Mount/Dismount
Toggle Switch is located on the back side of the hydraulic unit (Figure 2).
6. Install Xpress Lock Pin at the Plow Stand and Mount/Dismount Cylinder. See Figure 1.
Note: Under extreme circumstances the vehicle can generally be off 4 inches to either side of center line of the Hook
Assembly. The system can still attach itself properly to the lift frame, however, extra care should be taken to insure
the system is aligned and properly clamped onto the Lift Frame with Xpress Lock Pin installed.
WARNING
Xpress Lock Pin Part NO. 07288 MUST be installed through the clevis stand
u-clip and the mount ram tab when plow is attached to vehicle. This is a safety
feature that insures the clevis stand stays attached to the Lift Frame at all times
(See Mount Instructions and Figure 1).

General Maintenance
Meyer Products LLC recommends this maintenance information
for regular service. Sustained heavy operation may call for more
frequent service. Snow plowing subjects a vehicle to exceptionally
rugged use. As a result, it is very important to inspect and bring
the snow plow and vehicle up to maximum operating conditions.
Inspection should be made of both the vehicle and snow plow
prior to the plowing season and after each use.
Pre-season Maintenance
Scheduled vehicle maintenance should be performed as
recommended by the manufacturer.
Don’t forget that in addition to keeping equipment in order:
1. Keep windshield wipers, heaters and lights working.
2. Use emergency flasher lights for increased visibility and safety.
3. Equip vehicles with chains where necessary.
4. Provide operators with protective clothing and with rubber
gloves for handling snow melting chemicals.
VEHICLE ELECTRICAL SYSTEM
For maximum efficiency, the vehicle supporting the snow plow
must be properly serviced. The system should consist of at
least a 70 amp./hr. battery and a 60 amp alternator. Be sure to
check regularly:
1. Battery terminals to assure they’re clean and free of
corrosion.
2. Electrical connections, to assure they’re tight and corrosion
free.
3. Battery must be in top operating condition.
4. Alternator and regulator, to assure maximum electrical output.
SNOWPLOW
CAUTION: ALWAYS LOWER MOLDBOARD TO THE GROUND
WHEN SNOW PLOW IS BEING SERVICED OR WHEN
VEHICLE IS NOT IN USE.
Check the E-68 Diagnosis chart, pages 12-13, and Post Season
Maintenance, page 9, for advice on maintaining the unit.
1. Check and maintain hydraulic fluid reservoir level to 1” from
top cap. Oil level should be checked with lift ram and mounting
cylinder on the Xpress in the down or retracted position.
2. Check entire hydraulic system for leaks. A significant drop in
hydraulic fluid level is evidence of a leak which must be corrected
to prevent serious damage.
3. Before and after each season, remove sector pivot pins,
thoroughly grease pivot tubes and reinstall pins. Lubricate all
pivot points with chassis lube.
4. ADJUSTING TRIP SPRING TENSION FULL TRIP - Tighten
top locknut 4 turns beyond the point when spring coils begin to
separate. Tighten bottom locknut to hold eye bolt in position as
shown in figure 1. DIAMOND EDGE- Tighten adjustment nut to
the point when spring coils begin to separate.
Figure 1

5. RUNNERS
A. Inspect moldboard runners for wear and height adjustment.
B. Always replace runners as soon as they start to wear
through.
C. Adjust the runners to maintain cutting edge height of 1/2”
above ground in snow plowing position. (Can be set higher when
used on gravel driveways).
6. CUTTING EDGE
Replace the cutting edge as soon as it appears worn
approximately 4” on either corner. This will prevent permanent
damage to the moldboard.
7. MOUNTING BOLTS
Retighten all mounting bolts after first snow plowing session and
at regular intervals through the season.
8. DURA-SLICK™ POWDER COATING, both black and yellow,
should be checked at the beginning and end of each season for
any signs of rust. If any exists, use Meyer special Sno-Flo®
powder coat touch-up available in spray cans.
NOTE: PROTECTION AGAINST RUST AND CORROSION
When the power unit is not used for extended periods, protect
the chromed lift rod by fully extending and coating it with
chassis lubricant. On power angling models, coat the exposed
portions of the power angling cylinder rods with chassis lubricant
to protect against corrosion.
Post Season Summer Maintenance
1. Draining & Replacing Meyer M-1 Hydraulic Fluid
To drain mount cylinder (E-68 Only), fully extend and disconnect
both hose fittings and allow cylinder to leak back down to the
ground, draining it fully. Drain the fluid by removing the drain plug
located on the front side of unit next to the motor. To drain the
fluid from the power angling cylinders, disconnect the fittings
and completely retract the cylinder rods and purge cylinders and
hoses of all hydraulic fluid. The complete system should then be
flushed out with Meyer M-2 Flushing Fluid before adding new
Meyer Hydraulic Fluid.
2. Screen-Type Filters- Clean the filters with mineral spirits or
equivalent and blow out with compressed air.
3. Meyer M-1 Hydraulic Fluid is specially formulated with
an anti-ice additive for almost constant viscosity in subzero
temperatures. Because it is free-flowing in extreme cold, the unit’s
performance and efficiency are not affected by winter weather.
It is effective for a maximum of one year. Always carry an extra
quart of Meyer M-1 Hydraulic Fluid. Use of any inferior fluids
will void the Meyer warranty.
4. Refill power unit with Meyer M-1 Hydraulic Fluid by fully
retracting lift piston and mounting cylinder and filling reservoir to
1/2” below the filler hole. Note: Do not over fill unit, over filling
unit will cause oil to squirt out of the reservoir pressure relief valve.
Power angling rams should be collapsed. Install Hydraulic unit
and Moldboard assembly on vehicle. Remove reservoir pressure
relief valve (Filler plug) from top cap. To bleed air from the system
power angle moldboard side to side while maintaining a constant
check on the reservoir fluid level.
Note: It may be necessary to bleed air from the Power angling
cylinders by loosening the hydraulic fittings. Angle Moldboard
side to side until you have a steady stream of oil coming out of
fitting. Raise and lower the plow several times. With lift ram fully
retracted (down) check fluid level and replace filler plug.
-9-

SNOW PLOW STORAGE
1. When snow plow is disconnected, extend lift cylinder to end
of stroke and coat chrome rod with light grease. This fills the
cylinder with hydraulic fluid and protects the interior and exterior
from rust and corrosion.
2. Whenever Moldboard is disconnected, coat the exposed
portions of the power angling cylinder chrome rods with light
grease to protect them from corrosion.
3. Coat all pivot pins and other wear points with chassis lubricant.
Be sure to grease all zerk fittings.
4. Unplug electrical connection at power unit. Coat connection
with a dielectric compound to prevent corrosion and plug into
their corresponding weather plug.
5. Reference past season summer maintenance on page 9 prior
to final storage.

These charts are intended to be used as an aid in diagnosing problems on the E-68 Meyer Hydraulic Power Units. They are not a
substitute for factory training and experience. Be certain to read the General Information and Testing Tips sections before attempting
any troubleshooting. Additional detailed information as well as all electrical schematics may be found in Service Manuals 1-822.
GENERAL INFORMATION
Before any troubleshooting is started, make certain the following conditions are met.
1. The moldboard is pointing straight ahead. This can often be done by coupling the hose from the left cylinder into the right cylinder
and pushing the snowplow by hand.
2. The power angling cylinders must be installed correctly. The left cylinder has a hose with a female half of a coupler attached while the
right cylinder only has the male half of a coupler attached. Reverse them if installed on wrong side.
3. Mount Cylinder top hose has female coupler; bottom is male.
4. The electrical installation must have been made according to instructions supplied by Meyer Products LLC.
TESTING TIPS
Many tests do not require removing the Power Unit from the vehicle. However, more thorough testing can be done by using the Meyer
Test Stand which allows direct pressure and Amperage readings.
1. Use a screwdriver or other small tool to check for magnetism of solenoid coils (“A”, “B”, “C”, “D” & “E”). Place the tool on the nut
securing the coil and have an assistant operate the switch. You should feel strong magnetic attraction.
2. Use a test light or volt meter to determine whether there is power at harness or controller.
3. When determining Amp draw of motor, always obtain the highest value possible, i.e., at maximum raise or angle with motor running.
4. The pump shaft of a good pump can be turned smoothly using two fingers. If it can’t be turned easily, the pump must be replaced.
6. Pump pressure can be measured at an angle hose (note pressure at full angle) or in the pressure filter port (an adapter is necessary
for the filter port). (See Service Manual 1-822)
7. If hydraulic system is contaminated it is recommended that the hydraulic unit, power angling rams and hoses be drained and flushed
clean with M2 fluid. See page 24. The system should then be refilled with Meyer M-1 oil. See pages 9, 24.

PREPARING AREAS, USE OF GUIDE MARKERS
Every area to be plowed should be inspected before snowfall
for potential hazards. Holes should be repaired, raised manhole
covers leveled or noted and obstructions noted to prevent
damage to the plow mounting or vehicle undercarriage.
Markers or stakes with reflectors should be in position to indicate
boundaries of areas to be plowed, location of shut-off valves,
catch basins and other hazards. Markers should be at least three
feet above the ground; higher in areas of deeper snowfall.
The first step in organizing an efficient plan is to prepare a
map or procure a blueprint of the area. Locate and mark all
utilities, outlets, shutoffs, catch basins and possible emergency
equipment that must be reached from outside. Figure the square
footage of each area and the total area. Especially note areas
from which snow will have to be carried, call “trapped” areas.
Although hauling is expensive, it is necessary where piled snow
would limit access. Indicate clearing priorities on your map.
This may aid you in preparing a priority plan for your clearance
operation.
KEEP SNOW UNDER CONTROL
Deep or heavy, wet snow, because of its increased weight, calls
for more skillful and powerful plowing than light powder snow.
Efficient Snow Clearance Starts with Planning
Always plow in low gear and keep plowing. Heavy snow may
also require clearing a path or area for working room to move
snow to another area. Remember that wet snow weighs about
12 pounds per cubic foot. As it piles up in front of a snow plow
blade, the weight can quickly increase to several tons.
Where packed snow or ice must be plowed, it is sometimes
necessary to lower the cutting blade to rest directly on the road
surface. In that situation, plow in lowest gear for greatest power
to the cutting edge. This method also prevents the plow from
“climbing over” the icy surface.
If plowing very deep snow, 12 inches or more, you may have to
plow with the blade partially raised to shear off successive layers
of snow until a working area is clear. Then work small “bites” into
the edge. The “bite” depth should be inversely proportional to the
snow depth. A rule of thumb: 6-inch snow may be plowed with
the entire blade width; 9-inch snow with 3/4 of the blade width;
and 12-inch snow with only 1/2 of the width. Experience will
show what work can be done without stalling or getting stuck.
-14-

Selecting Equipment
Where you plan to plow, and the conditions under which you will
be plowing, determine to a great extent the type of vehicle you’ll
find most useful. In general, three types of vehicles are available
as the power source of snow clearance. Each type has certain
inherent advantages depending upon the particular
situation.
Four-wheel drive HEAVY DUTY TRUCKS have proven most
effective in heavy duty snow plowing situations using the E-Z
Mount Xpress™. They have excellent traction and the Xpress™
handles with ease.
Two-wheel drive TRUCKS, particularly those of 1 to 3 tons, are
best for straight line road clearance and in large open areas.
TRACTORS are effective for trapped areas in which visibility is
limited, plus a rear grader blade can be used in conjunction with
the Meyer Snowplow.
Meyer Snowplow’s custom design for specific vehicles provides
the advantage of easy, fast attaching and detaching. This feature
permits utilization of vehicle versatility as weather conditions and
job requirements demand.
20 m.p.h. is a maximum snow plowing speed under ideal
conditions, assuming the driver is familiar with the roadway or
area to be cleared. Under unfamiliar or hazardous conditions, or
if there is poor visibility, we recommend reduced speed and
extreme caution.
Careful analysis of the area you intend to clear of snow will
direct you to the types of equipment you’ll require. Check Table
1, Average Hourly Snow Clearing Capacities, for recommended
equipment depending upon the area in which you’ll be working.
Then, match the vehicles you already have with the snow removal
equipment you need. If your vehicles do not have the
capacity to clear all major access areas within two hours, you
should increase clearing capacity with additional equipment or
arrange for assistance through a contract plowing service.

Plow with the Storm
It is of utmost importance to remember one basic rule — Always
plow with the storm. Start plowing when snow is 1 to 4 inches
deep, depending upon traffic or other limitations. Heavy wet
snow can be very hazardous when just 1 inch is on the ground.
Accumulations of more than 4 inches can be very difficult to
clear.
Plow with the Storm Angle Moldboard for Optimum Results.
You will not be able to plow snow of any significant depth straight
ahead for more than a short distance. Set the moldboard at the
best angle for rolling snow sideways in the desired direction.
The snow plow path, in the angled position, should exceed the
tire track by at least six inches on either side. Be sure to have
enough slack in the lift chain while plowing so the cutting edge of
the moldboard can follow the ground contour. Use the adjustable
runner shoes to set the bottom edge of the plow just above the
ground for best operation.
It’s important to recognize the significance of even a few inches
of snow. Besides being slippery, especially when wet, snow
can be extraordinarily heavy, and make auto travel impossible.
Snowfall of just 1 to 3 inches will produce hazardous traffic and
roadway conditions even for experienced drivers.
Snow is heaviest when wet, and most difficult to handle. The
National Weather Service reports that a 6-inch, average weight
snowfall on a 200 x 200 foot parking lot weighs 62 tons. Heavy,
wet snow for the same area might weigh as much as 248 tons.
If the heavy snow had to be hauled away, you’d need 74 full
loads on a l0-yard truck.
Obviously, the only way to assure clear traffic areas is to be
prepared with the proper equipment and expertise to open
arteries and areas to traffic. Remember to keep current with
accurate snowfall information from local weather bureaus via
radio and television.

These two snow plowing techniques have been time- and
operation-tested. Use them as guidelines for most snow
plowing strategies. Plan I is for smaller areas of 50,000 sq.ft.
or less. Plan II is for larger establishments having more than
50,000 sq.ft. to be cleared.
PLAN I (less than 50,000 sq. ft.)
Recommended equipment: A four wheel drive vehicle; a ST-7 or
ST-7.5 snow plow; snow shovels; and ice control equipment.
Recommended procedure: PLOW WITH THE STORM.
Begin plowing at the suggested accumulation for your type of
establishment (i.e., 1” for commercial and institutional areas; 2”
for industrial establishments; 3” for municipal and residential
areas.) Continue until snow has been cleared. Don’t forget
- snowfall often surpasses weather forecasts. A well planned
clearing schedule will help prevent the necessity for expensive
emergency action.
A typical small-area strategy:
1. Keep in touch with local weather forecasts for preparatory
measures.
2. Notify scheduled personnel.
3. Have vehicles and equipment inspected, fueled and ready.
4. Clear area by pushing snow first to sides of drives, around
perimeters of parking areas and away from loading docks and
platforms. It is often true that the smaller the establishment,
the greater the proportion of “trapped” areas which will require
snow to be hauled away. Always deposit snow as far back as
possible for greatest use of dumping areas.
5. Use snow shovels to clear walks, gates and doorways.
6. Treat with snow-melting materials as needed.
PLAN II (over 50,000 sq.ft.)
Recommended equipment: The suggested number of vehicles,
according to the Table “Average Hourly Snow Clearing Capacities”,
on page 15, with ST-7 to HM-10 snow plows; front end loaders
if needed; snow shovels and ice control equipment.
Recommended procedure: As always, PLOW WITH THE
STORM. Begin plowing at the suggested accumulation for
the area and continue as required. Actual snowfall frequently
exceeds forecasted conditions. Well-planned snow clearance
strategy reduces the chances for expensive emergency action.
Snow Plowing Tips from the Pros
Two Established Snow Clearance Plans
-17-

SNOW PLOWING OPEN AREAS
Open areas such as parking lots require a more serious approach
to planning, where to begin, and where snow can be stacked at
the edges. The following will help in making a plan, thus turning
out a neat, professional job.
Always turn on warning flashers and/or use yellow warning
beacon or strobe light when plowing. Then make a single pass
down the center on the longest dimension. Angle plow the snow
toward the long sides with continuous passes until the area is
cleared and snow is all stacked around the outside edges.
For larger areas, efficient plowing calls for clearing area
immediately in front of buildings and working away from buildings
toward the outer limits of the area. When snow is quite deep,
it might be necessary to push the excess into piles out of main
traffic lanes for later handling. Areas 100,000 sq.ft. or more
— once the main artery is clear, it is usually most efficient to plow
at right angles to the artery, piling up windrows by back and forth
passes in alternate lanes. The windrows can later be pushed out
of the way or left as is depending upon conditions.
To clean up remaining snow, you can put the blade in the straight
position. Buck piles from either side to stack snow. The blade
will automatically “ride” up the pile to make stacking easier.
On a dirt or slag surface, drop moldboard to ground in straight
position, then raise one inch or adjust runners for desired
clearance. Under extreme surface conditions it may be necessary
to plow with moldboard in suspended position.
PARKING LOTS
1. Always turn on warning flashers and/or use yellow warning
beacon or strobe light when plowing.
2. Make first pass to clear area into which you will later push
more snow.
3. Clear front in straight position and clean up remaining
snow. Buck piles from either side to stack snow. Blade will
automatically “ride” up pile to aid in stacking.
