Attaching the Snow Plow
to the Prime Mover
NOTE
Before attempting to attach
the Snow Plow to the prime
mover, verify that all hydraulic
couplings are compatible.
CAUTION
Hydraulics should operate in an
even and smooth manner.
Hydraulic movement that is not
even and smoo
th may indicate
that air is in the hydraulic lines.
WARNING
Improper
attachment to the prime
mover may cause personal injury.
CAUTION
All hydraulic connections must
be clean and free of debris
before making any connection.

Place the Snow Plow attachment on a level surface.
Position and align the prime mover to the rear of the
attachment, within proximity of the front of prime mover.
Insert and connect the prime mover into the
a
ttachment. Connect the hydraulic lines from the
attachment to the prime mover.
Close latches (or othe
r locking mechanism) to secure
the attachment to the prime mover.
Using the prime mover,
raise the attachment and move
the attachment to ensure h
ydraulic lines are clear of air
and operate properly.
Lower the attachment to ground level.
Route hoses away from pinch areas
– install cable
ties if necessary to assure extended hose life.
Inspect that the attachment is mounted properly and
securely. If t
he attachment does not meet this
requirement, follow the instructions to remove the Snow

Multi-Blades
The Blue Diamond Attachments Multi-Blade attachment
has become a necessity among plowing contractors
today. This unique Snow Plow is offered for a variety of
applications.
Blue Diamond Attachments Multi-Blades
Snow plows are designed by people with years of
experience in harsh Minnesota winters. You can be sure
that the quality of the Multi-Blade is our first priority.
The Multi-Blade has been designed for absolute maximum
durability and efficiency, regardless of snow conditions.
Extra tight blade curl reduces horsepower requirements to
get snow rolling, 35° angle gives you the most efficient
snow discharge, and our patent pending spring-assisted
down pressure lets you scrape like no other! Simply put,
you’ve purchased the world’s finest snowplow!!
P.S. Wolves are not usually solitary animals.
They like to work in packs!

Removing the Snow Plow
from the Prime Mover
WARNING
Improper disconnection
may result person injury or
damage to t
he attachment
and prime mover.
CAUTION
All hydraulic connections must
be clean and free of debris
before disconnection.
NOTE
Hydraulic connections must be
disconnected before
disengaging latches to prevent
damage to the prime mover or
the attachment.
1. Using the prime mover, lower the attachment to the ground.
2. Relieve the pressure in the hydraulic system by following these
instructions:
a. Turn the ignition to off.
b. Turn the ignition back to the on position without starting the machine.
c. Move the auxiliary hydraulic function lever back and forth to relieve the
pressure in the hydraulic lines. (This will greatly assist you when
hooking the unit back up so that the hydraulic couplers connect easily)
3. Disconnect the hydraulic connection between the attachment and the prime
mover. To prevent contamination, remove any dirt and debris from the
couplings.
4. Disengage the prime mover latches (or other locking mechanism) from the
attachment.
5. Move the prime mover from the attachment.

Operation &
Maintenance
NOTE
Replace any damaged
hardware, hoses, and
fitting before using the
equipment.
WARNING
Do not use hands to check
for hydraulic leaks. Keep
body parts away from
leaking hydraulic lines and
couplings that are under
pressure.
DANGER
Keep all body parts away
from the Snow Plow
when in use. The
pivoting blade is
dangerous and
hazardous and could
potentially cause serious
bodily injury or death.
Inspection Checklist
√Are all safety
notices and warning
stickers in proper
locations and visible? √
Are there any visible
hydraulic leaks?
√Are any cracks
visible in Snow Plow
structure?
√Is the cutting edge
worn or bent?
√Are the bolts
holding blades
secure and tight?
√Has the prime
mover been properly
inspected for hydraulic
leaks and proper tire
inflation?
√Has the prime
mover been properly
maintained?
Equipment Inspection
It is recommended to inspect the equipment for damage and wear
before use. Use the following list as a guideline during equipment
inspection.
•Check all hardware connections to the prime mover for
damage or fatigue such as cracks or other structural flaws.
•Check that all latches or locks are closed.
•Check that all hydraulic fittings are tight and free of leaks
•Check that all hydraulic lines are free of leaks, holes, or
cracks.
Check that the tires on the prime mover are in good condition and have
proper load ratings.
Usage Guidelines
Before each use do the following:
•Perform the equipment inspection by performing a walk
around.
•Perform daily inspection as indicated in the Inspection
Checklist.
•Verify that the proper attachment is being used for the task.
Operation
Always be sure the A-frame of your Multi-Blade is level (perpendicular)
with the ground when plowing, to insure proper cutting edge wear. You
can regulate the scraping ability of your Multi-Blade by increasing or
decreasing the down pressure you apply via your tilt cylinders. The
angle of your Multi-Blade can be changed at any time by using your
auxiliary circuit. As you become experienced with the Multi-Blade, you
will find its productivity will amaze you.
If you are on extremely uneven ground, you may prefer to raise your boom
arms slightly, lower the Multi-Blade to the ground using your tilt cylinders,
then put your boom arms in the float position (if machine is equipped) to
better follow the contours of the ground. You will learn from experience
what works best for you in each situation.
Operation Continued

9
The Multi-Blade has been designed to
stack snow if you wish. This will not
damage the plow no matter how high you
push it into a pile of snow. Watch your
hose routing carefully so as not to stretch
and ruin your hoses.
DANGER – Always be aware of what is
overhead.
Maintenance
Disconnect the hydraulic connection between
the attachment and the prime mover before
performing any type of maintenance to the
Snow Plow.
Inspect the Snow Plow daily before use. It is also recommended to inspect the Snow
Plow after extreme use or damage. Us the following inspection checklist as a guideline.
•As with any power attachment, safety is critical. An enclosed cab prime mover
with the operator wearing safety protection is required.
•Never operate the Snow Plow with persons within 100 feet.
•Disengage Snow Plow and shut off engine before leaving the cabin of the
prime mover.
•Keep all body parts away from the Snow Plow when in use.
•Use caution on slopes and uneven terrain.
•Never carry passengers.
•Never leave machine running unattended.
•Never leave Snow Plow off the ground when out of operator’s seat.
•Never allow children or untrained personnel to operate the snowplow! STAY
CLEAR
Cutting Edge
Be certain to replace bolt-on cutting edge when it wears within 1/2” -3/4” of the
bolt head securing it to the trip-edge. Replace only with genuine Blue Diamond
Attachments cutting edge and hardware.
Cylinder Gland Nut
Periodically check cylinder gland nuts for tightness. Usually they will leak first if they
become loose. A large slip-joint pliers or pipe wrench can be used to tighten. Do not
over tighten!
Hoses
Check hoses occasionally for abrasion damage. This may save you from downtime. If
in doubt, replace with genuine Blue Diamond Attachments parts.
Pivot Pins
Pivot pins may be lubed with moly-type grease, same as used on your machine. Please
check the cotter pins that retain all pivot/anchor pins after each use. If missing,
replace! Severe damage could be caused by losing a pin.
Springs
Multi-Blade springs are adjusted by the two large jam nuts on the rod between each
spring. Springs are adjusted correctly when you can fit a business card between the
coils. It is very important to set them after your first use, then twice per year
thereafter. Use of grease or “Anti Seize” on the rod and jam nuts will keep them from
rusting to each other.
Storage
Lubrication of pivot pins is recommended if unit is stored outside. Be certain
hydraulic quick couplers are cleaned and joined together to keep dirt out. Put a light
coating of grease on exposed rod portion of cylinders to prevent corrosion. Touch-up
paint should be used on all scratches to prevent further rust.
