SAFETY PRECAUTIONS

Improper installation and operation could cause
personal injury and/or equipment and property damage.
Read and understand labels and the Owner's Manual
before installing, operating, or making adjustments.

WARNING

Lower the blade when the vehicle is parked.
Temperature changes could change
hydraulic pressure, causing the blade to
drop unexpectedly or damaging hydraulic
components. Failure to do this could result in
serious personal injury.

WARNING

The driver shall keep bystanders clear of the
blade when it is being raised, lowered, or
angled. Do not stand between the vehicle and
the blade or within 8 feet of a moving blade. A
moving or falling blade could cause personal
injury.

WARNING

Keep hands and feet clear of the blade and
A-frame when mounting or removing the
snowplow. Moving or falling assemblies could
cause personal injury.

WARNING

Do not exceed GVWR or GAWR including
blade and ballast. The rating label is found on
driver-side vehicle door cornerpost.

WARNING

To prevent accidental movement of the blade,
always turn the control OFF whenever the
snowplow is not in use. The power indicator
light will turn OFF.

WARNING

Remove blade assembly before placing
vehicle on hoist.

CAUTION

Refer to the current eMatch selection system
for minimum vehicle recommendations and
ballast requirements.

HYDRAULIC SAFETY

WARNING

Hydraulic fl uid under pressure can cause skin
injection injury. If you are injured by hydraulic
fl uid, get medical attention immediately.

• Always inspect hydraulic components and hoses
before using. Replace any damaged or worn parts
immediately.

• If you suspect a hose leak, DO NOT use your
hand to locate it. Use a piece of cardboard or
wood.

FUSES

The FISHER® electrical and hydraulic systems
contain several automotive-style fuses. If a problem
should occur and fuse replacement is necessary,
the replacement fuse must be of the same type and
amperage rating as the original. Installing a fuse with
a higher rating can damage the system and could start
a fi re. Fuse Replacement, including fuse ratings and
locations, is located in the Maintenance section of the
Owner's Manual.

PERSONAL SAFETY

• Remove the ignition key and put the vehicle in
PARK or in gear to prevent others from starting
the vehicle during installation or service.

• Wear only snug-fi tting clothing while working on
your vehicle or snowplow.

• Do not wear jewelry or a necktie, and secure long
hair.

• Wear safety goggles to protect your eyes from
battery acid, gasoline, dirt, and dust.

• Avoid touching hot surfaces such as the engine,

CAUTION

Assembling a hose to the incorrect wing ram
port can result in permanent damage to the ram.

FIRE AND EXPLOSION

WARNING

Gasoline is highly fl ammable and gasoline
vapor is explosive. Never smoke while
working on vehicle. Keep all open fl ames
away from gasoline tank and lines. Wipe up
any spilled gasoline immediately.

Be careful when using gasoline. Do not use gasoline
to clean parts. Store only in approved containers away
from sources of heat or fl ame.

CELL PHONES

A driver's fi rst responsibility is the safe operation of
the vehicle. The most important thing you can do
to prevent a crash is to avoid distractions and pay
attention to the road. Wait until it is safe to operate
Mobile Communication Equipment such as cell phones,
text messaging devices, pagers, or two-way radios.

VENTILATION

NOISE

Airborne noise emission during use is below 70 dB(A)
for the snowplow operator.

VIBRATION

Operating snowplow vibration does not exceed 2.5 m/s2
to the hand-arm or 0.5 m/s2 to the whole body.

TORQUE CHART

CAUTION

Read instructions before assembling.
Fasteners should be fi nger tight until
instructed to tighten according to the torque
chart. Use standard methods and practices
when attaching snowplow, including proper
personal protective safety equipment.

WARNING

Vehicle exhaust contains lethal fumes.
Breathing these fumes, even in low
concentrations, can cause death. Never
operate a vehicle in an enclosed area without
venting exhaust to the outside.

BATTERY SAFETY

Batteries normally produce explosive gases,
which can cause personal injury. Therefore,
do not allow fl ames, sparks, or lit tobacco
to come near the battery. When charging or
working near a battery, always cover your
face and protect your eyes, and also provide
ventilation.

• Batteries contain sulfuric acid, which burns

• Disconnect the battery before removing or

HEADGEAR TO A-FRAME ASSEMBLY

NOTE: For easier assembly and installation,
vehicle and all snowplow components should
be on a smooth, level, hard surface, such as
concrete.

1. With the vehicle parked on a solid level surface,
measure the distance from the center of the
connecting pin hole to the ground. Using this
measurement, refer to the hole selection chart
below to determine which hole should be used to
attach the headgear to the A-frame.

6. Adjust the lift chain so there are an equal number
of links on each side of the lift arm. Then, while
supporting the headgear, remove and retain the
four pins and discard the shipping brackets.

7. Lower the jack leg in the headgear assembly so
that eight complete slots are showing through the
top of the headgear cross bar.

8. Release the jack lock to hold the jack in place.
Place the headgear assembly on top of the
A-frame assembly so that the headgear is tipped
backward and the jack leg is in between the
A-frame and push assembly.

2. If the vehicle is unavailable, use the middle holes
and reposition the headgear later, if necessary.

3. Set aside the parts bags, pivot bolt, and blade
guides. The vehicle electrical harnesses and
Owner's Manual packet are in the bag with the
headlamps box.

4. Remove the hardware and board(s) securing the
A-frame to the pallet.

5. Remove the hardware and bracket securing the
headgear to the A-frame.
