Cleaning and General Maintenance
For best results, and to maintain the finish of the
KV552, clean or wash the V-blade to remove dirt,
gravel, and salt deposits. Remove any ice or snow
accumulations from the blade and frame.
Attention
To maintain the finish of the power unit and attach
-
ment, thoroughly wash the equipment after each
use to remove any corrosive agents (e.g., salt). Fail-
ure to clean the equipment may result in corrosion
of (including but not limited to) steel, aluminum, and
electrical components. Equipment that will experi-
ence repeated exposure to corrosive agents should
be pretreated with a corrosion preventative.
Cutting Edge Reversal/Replacement
If the cutting edges wear down near the blade frame
structure, remove the cutting edges and flip over so
the unworn top edge is now on the bottom. Reinstall
the cutting edges onto the V-blade. When both sides
of the cutting edges have been worn down, the cut-
ting edges will need to be replaced. Always reverse
or replace both cutting edges at the same time.
NOTE: It is normal for the forward edge of the cut-
ting edges to wear faster than the rest of the cut-
ting edge, if the V-blade is used extensively in the
swept forward position or in the left and right angled
positions. To help minimize this effect, make sure
the blade is level from side to side and that the skid
shoes are adjusted properly.
Skid Shoe Replacement
Skid shoes should be replaced when wear surface is
less then 1/8” thick.
Leveling Blade - Side to Side
1.
Make sure the power unit tires are inflated to the
correct pressure.
2. With the V-blade attached to the power unit and
the power unit parked on a level surface, adjust
both wings until they are straight out perpendicu-
lar to the power unit.
3. Disengage the power unit’s weight transfer sys-
tem (if equipped).
4. Lower the V-blade to the ground and place the
power unit’s primary S.D.L.A. lever in the float
position by pushing it to the right until the detent
engages.
5. Check to see if the cutting edges are making even
contact with the ground. If they are not making
even contact, raise the blade all the way up and
support securely with blocks or jack stands.
6.
When making adjustments with the V-blade in the
raised position, the V-blade hitch frame must be
supported securely with blocks or jack stands.
Hydraulic drift or accidental release of hydraulic
pressure could allow the V-blade to lower and
trap a person or appendage, if the V-blade is not
securely supported.
Loosen the 5) 1/2” bolts that fasten the center
frame to the center hinge shaft and the center
skid shoe.
7.
1/2” Bolts
Sliding the center frame left or right in relationship
to the center hinge shaft will raise or lower the
outside corners of the blade wings. Moving the
bottom to the right will raise the right side of the
blade and lower the left side and moving it to the
left will do the opposite. It may be helpful to use
a jack or hoist to lift the appropriate side of the
blade and then tighten the 1/2” bolts.
8. Repeat steps 4 and 5. If blade is still not level,
repeat steps 6 and 7.
9. When the blade is level, tighten the 1/2” bolts to
80 ft-lbs (108 nm).
SERVICE
Always set the parking brake, shut off power
unit engine, remove the ignition key, and ensure
all moving parts have come to a complete stop
before inspecting components or attempting any
repair or adjustment.
Attention
If any component requires replacement, use only
original Ventrac replacement parts.
