General
• Before operating, perform a thorough visual inspec-
tion of the equipment. Look for fluid leaks, cracked,
bent or broken components, loose nuts, bolts or
attachments and proper fluid levels.
• A clean hydraulic system is essential to long pump
life and proper performance.
• When adding oil to the reservoir, wipe the area
around the filler port clean before
removing the
breather cap. Use clean oil and a clean funnel, (DO
NOT use a cloth or rag to strain the oil).
IMPORTANT:
Hydraulic unit comes from factory
charged with Type 5606. If additional oil is added it
must be compatible with Type 5606. If another type of
oil has been used in the system the same type of oil
must be used for topping off system.
• The operational environment for snow plows is an
extremely harsh and corrosive one.
• Ensure all electrical connections are clean and
tight.
• To prevent rust from forming, clean and repaint
exposed metal surfaces.
• NEVER operate the equipment with the protective
covers or guards removed.
Break In Period
During the first few hours of operation the Plow will go
through a break in period during which mating surfaces of
the A-Frame and Swing Frame pivots will settle in. After
15 to 20 hours of operation check for free play of the
A-Frame and Swing Frame Pivot.
To check for free play:
• raise the plow and install the transport lock. See
“Installing The Transport Lock Clamp on page 10.
• push down on end of blade, either right or left side, as
far as it will go
• using a tape measure, measure and record the
distance from the ground to the bottom edge of the
wear strip
• Pull upwards on the same end of the plow until edge
of blade is raised as far as it will go
• measure and record the distance from the ground to
the bottom edge of the wear strip
• Subtract the two measurements to determine the
amount of free play between the Swing Frame Pivot
and the A-Frame
NOTE: Allowable free play range is 1/2" to 1-1/2". If free
play exceeds this range it must be adjusted using the
following steps.
To remove any excessive free play:
• remove the 3/8" Cap Screw and Lock Nut which holds
the Lock Plate to the Pump Platform (See Figure
2-2)
• tighten the Pivot Bolt Nut (typically 1/6 to 1/3 turn, one
or two flats)
• replace the Lock Plate and secure with the 3/8" Cap
Screw and Lock Nut.
Periodic Inspection
After approximately every 20 hours of operation perform
the following inspections procedures:
1. Inspect the plow assembly including the Subframe
assembly for any damage or excessive wear. Also
inspect all fasteners to insure that they are properly
tightened. If any fasteners are loose re-tighten to the
proper torque (Refer to the Torque Specification chart in
this manual). Also carefully inspect adjacent area for
damage or wear as well as carefully inspecting all
adjacent fasteners for proper torque.
2. Apply a small amount of light oil to the Hitch Pins and
pivots, to Pivot Pins between the Blade Assembly and the
Swing Frame, between Lift and Swing Cylinder pivot Pins
and the Lift Linkage Pivots.
3. Check for excessive free play between the A-Frame
and Swing Frame Pivot. See “Break In Period on page
18. If there is excessive free play adjust the Swing Frame
Pivot Pin as described in the "Break In Period" section
on page 18 of this manual.
NOTE: If wear is noticed between the A-Frame and
Swing Frame apply a good quality Anti-Seize lubricant to
this area.
Hydraulic Cylinders
To avoid corrosion during storage, coat the exposed
(chrome) portion of the lift and angle cylinders with a light
grease.
Electrical Quick Disconnect Plug
Install protective covers on quick disconnect ends to
prevent corrosion from forming on terminal ends during
storage or when plow is disconnected from vehicle.
