SAFETY INST UCTIONS
• Read all installation, safety and maintenance instructions completely before
operating this equipment
• Keep all personnel clear of moving parts while equipment is being operated.
• Do not operate equipment in need of maintenance! Repair immediately!
• While operating this equipment, use common sense, use caution, be alert
and be safety-conscious.
AVOID HIGH-PRESSURE FLUIDS
Escaping fluid under pressure can penetrate the skin causing serious injury.
Avoid the hazard by relieving pressure before disconnecting
hydraulic or other lines. Tighten all connections before applying pressure.
Search for leaks with a piece of cardboard. Protect hands and body from
high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid injected into
the skin must be surgically removed within a few hours or gangrene
may result.
CAUTION: “Stacking” (piling) of snow with a push plow is not recommended
Raising the plow too high while stacking can damage the plow and mount by causing
the lift arm to fold up and contact the moldboard
Do not lift the plow more than 18” off the ground with piling and stacking snow
Where possible, start the snow season by pushing snow as far back as possible from
the area begin plowed to avoid having to move or stack it later

MAINTENANCE INST UCTIONS
Off Season:
• Use care when disconnecting hydraulic lines to assure that no dirt or foreign
objects enter the hydraulic system. Use caps to cover hydraulic hose fittings
and insert plugs in hydraulic ports.
• Hydraulic cylinders should be fully retracted when stored during the off season
to prevent damage or corrosion. The remaining exposed shaft surface should
be coated with a thick grease to prevent corrosion, which must be removed
before returning to regular service.
• Check mounting bolts for wear and/or damaged threads and replace before next
season.
In Season:
• Check for loose bolts and nuts daily, and re-torque before use. (Failure to
inspect equipment on a daily basis may seriously affect safety and/or efficiency.)
• Lubricate all grease fittings every ten hours of normal use and more frequently
under heavy use.
• A cross over relief valve (1800 PSI) MUST be plumbed into the reversing circuit.
• Check all hydraulic fittings for tightness on a regular basis.
• System pressure should NOT exceed 2000 PSI.
• Check cutting edge for wear. Do not let cutting edge wear closer than 1⁄2" to
3⁄8" from the bottom angle of the moldboard.
• Due to the nature of use and environment this equipment is operating in,
damage and wear may occur at anytime. Therefore, Monroe Truck
Equipment recommends the end user establish and follow a daily inspection
routine before using this equipment.

Possible serious injury and equipment dam-
age from loosening of equipment fasteners.
Fasteners on snow and ice removal equipment may
loosen due to vibration and repetitive movements.
Retighten all equipment mounting fasteners after the
first 8 hours of use, then check tightness weekly after
that. Use a torque wrench when specific torque val-
ues are given in the installation manual.
If fasteners need to be replaced, be certain to use the
correct size, grade and type to prevent failure.

Springs under tension!
If spring releases while
performing maintenance,
serious injury or death
could result. Use caution
when working in area.
