Weight Kit Installation (s/n C1017A+)
These instructions apply to an installation of an optional
407-904A weight kit.
Note: This kit is compatible only with applicators having
serial numbers C1017A or higher. C1016A and
earlier applicators have a mechanically
incompatible rear sub-frame.
Tools Required:
• Lift or hoist with a capacity of at least 750 pounds
(340 kg). Two lift lines, each with a capacity of at least
750 pounds (340 kg).
• Tractor for raising and unfolding the applicator.
• Basic hand tools.
1. Raise and unfold the applicator. Leave it hitched or
install parking stands.
Heavy Overhead Object Hazard:
Move only one weight stack at a time. Use an adequate hoist.
Use two or more lines, each rated for the full weight of a single
weight stack. Inspect lines for wear and damage. If the hoist
fails or tips, or a line fails, a weight could fall or swing,
causing serious injury or death.
Refer to Figure 108
2.
Locate one:
160-296S NTA WEIGHT BRACKET ASSY
Observe that a weight stack is not symmetrical. The
weight base has a long (outside) notch
and a
short (inside) notch .
3. As needed, orient the weight stack prior to line
attachment, so that it is in the correct orientation
when placed on the frame.
4. Connect hoist lines to the weight mounts .
5. With the longer notch toward the wings, and the
shorter notch to machine center, place the weight
in the openings of the rear sub-frame. Push it fully to
the rear before releasing the lines.
6. Select two sets:
407-991D BRACKET STOP
802-226C HHCS 1/2-13X2 3/4 GR5
804-015C WASHER LOCK SPRING 1/2 PLT
803-020C NUT HEX 5/8-11 PLT
Assemble the stop pair on either side of the
weight support bar . Snug against weight stack .
Secure with bolts , lock washers and nuts .
7. Repeat step 2 through step 6 for second weight
stack.
Heavy Overhead Object Hazard:
Do not stand to either side of an elevated weight stack. Keep
body parts away from gaps between the stack and other
machine parts. Remain behind and out from under the elevated
weight stack. Move the stack slowly and carefully. Assume a
line could fail, and that the weights could swing down and to
the side.
Machine Damage Risk:
Do not install a single weight on either side. Do not leave
weight pairs uncoupled on either side. Always install or
remove all four weights. When installed, always use provided
fasteners to couple front and rear weights at their mounts
.
Weights are held in place largely by gravity. A single weight,
or uncoupled pair, could tip forward during a sudden stop,
causing machine damage.
