DO NOT use this product if any of the components are cracked. DO NOT exceed the rated load limit of the unit. DO NOT make alterations or modifications to the unit. DO NOT remove or obscure warning labels. Keep hands, feet and loose clothing away from moving parts. Some procedures described in this manual require work inside the indicator enclo-

sure. These procedures are to be performed by qualified service personnel only.

Always be certain when lowering the scale that everyone is clear of the scale and any moving parts.

Use two hands when gripping the lift handle to raise or lower the scale. Be sure the gates are latched or tied inward before transporting the scale. Ensure all three hitch lock pins are installed and the suspension stops are in the

transport position before moving the scale.

This unit is not intended for the transportation of livestock or any other goods. Any addition of weight to the scale in transport mode may cause premature component failure and voids the Rice Lake warranty.

Animal Safety:

Animal safety is a very serious issue and must be observed when handling any type of animal.

The scale surface may become slippery during use; a build-up of manure on the scale may reduce traction. It is recommended that you take any necessary precautions to maintain an acceptable level of animal footing.

Calibration:

Do not calibrate this scale with a weight cart having a gross weight in excess of 4,000 lbs or 1,815 kg. This device is designed to be calibrated with single block weights spread evenly throughout the floor of the scale. Shift tests should not be done with more than 4,000 lbs or 1,815 kg in a 4’ x 4’ area. Failure to comply with this warning will result in damage to the scale and void the warranty.

Introduction 5

1. 2 Ov e rv i ew

The MAS-M is an agricultural implement consisting of a scale with air ride suspension and swing out hitch, sheeted animal cage suspended by four S-type load cells through a cam style On-Board scale system, and weigh center. In transport mode the scale system is locked down, protecting the load cells from damage during transport. To convert to weigh mode the entire scale is lowered to the ground, the hitch is spl it and swung outward and the scale is raised to the weigh mode using a lever and cam system. The weigh center contains the digital indicator and ticket printer. To convert back to transport mode the process is reversed (lower the scale, swing hitch inward and lock and raise the suspension using the integral air pump).

The MAS-M can be used on any firm surface up to 7% grade (4-degree slope) and has a low deck height (6”) for easy step in.

1.3 Lifting Instructions

Lift the scale only in designated locations (see Figure 1-5). The scale may be lifted by forklift (ensuring the forks reach through both walls) or by 4 straps and a crane or loader. Ensure the scale is in the transport mode (locked down – see next section) when loading and transporting the scale.

2.0 Assembly

Note

Lifting Fixture

Nylon Locknut

2.1 Unloading

2.1.1 Install one lifting fixture on each of the four corners.

If lifting fixtures are in place, skip to Section 2.1.2

1. Remove the nylon locknut from the bolt inst alled for shipping.

2. Place the lifting fixture with small hole over the bolt.

3. Reinstall the nut leaving the fixture free to move.

Figure 2-1. Lifting Fixture

2.1.2 Slinging the scale.

The MAS-M can be slung using 4 straps conn ected from the lifting lugs to a single point in the center. To obtain a lifting point closer to the center of gravity straps should be 1 to 2 ft longer on the rear of the scale. See Figure 2-2.

• Strap length 8 x 13 = 6 ft minimum

• Strap length 8 x 18 = 9 ft minimum

Figure 2-2. Slinging the Scale

2.1.3 Lift the scale.

Shipping Stub

Note

1. If stacked, monitor the four corners directly below the lifting fixtures.

2. Each corner has a shipping stub inserted, these stubs are not bolted in place, ensure they remain with the lower scale.

3. Once the upper scale of the stack is removed the stubs can be discarded.

Figure 2-3. Shipping Stub

4. The scale can now be stored as is or placed on a relatively flat location to be assembled.

2.2 Package Removal

The indicator and tires are shrink wrapped for transportation. Be careful when removing to avoid damaging the indicator or tires when removing.

1. Remove the tires and indicator, then re-strap the walls if the scale is to be transported while packaged.

The bolt that holds the walls and the cross members in place during shipping is not used for assembly.

Please recycle the packaging material. Place the parts safely and in a location they will not be damaged.

2.2.1 Wheel Assembly and Torque Specification

Note

It is extremely important to apply an d maintain proper wheel mounting torque on the scale axle. Torque is a measure of the amount of tightening applied to a fastener (nut or bolt) and is expressed as length times force. For example, a force of 90 pounds applied at the end of a wrench one-foot long will yield 90 ft-lbs of torque. Torque wrenches are the best method to assure the proper amount of torque is bein g applied.

Wheel bolts/nuts must be tightened and maintained at the proper torque levels to prevent loose wheels, broken studs and possible dangerous separation of wheels from the axle. Be sure to use only the fasteners matched to the cone angle of the wheel (usually 60° or 90°).

The proper procedure for attaching the wheels is as follows:

1. Start all bolts/nuts by hand to prevent cross threading.

2. Tighten bolts/nuts in the sequence shown in Figure 2-4.

The tightening of the fasteners should be done in stages, following the recommended sequence, tighten fasteners per torque chart in Table 2-1.

3. Wheel bolts/nuts should be re-torqued after the first 10 miles, 25 miles and again at 50 miles.

Wheel Torque Sequence (ft-lbs)

1st Stage 2nd Stage 3rd Stage

20-25 50-60 90-120

Table 2-1. Wheel Torque

Figure 2-4. Wheel Torque Pattern

4. Once the wheel nuts have been torqued use a white marker to mark the end of each stud to show they have been torqued.

2.3 Cage Assembly

Silicone

Wall Insert

WARNING

Note

2.3.1 Apply the silicone bead

Before installing the walls a silicone bead must be added.

1. Clean the upper flange of the floor and the lower wall flange with mineral spirits.

2. Apply an 1/8” bead of silicone along the upper edge of the floor pane l along the entire length as shown in Figure 2-5.

Figure 2-5. Silicon Bead

2.3.2 Install walls

Wall installation should be done with 2 people or an overhead crane.

1. Lift the first wall by using one sling in the center.

The wall with the operator’s instructions is mounted on the left side.

2. Stand the wall vertical and place the inserts from the wall into the tubes of the cage floor. The more vertical the wall the easier assembly will be.

3. Repeat for the opposite wall.

4. Install the top cross members.

5. Insert the 3/4 x 3 1/2” bolts t hrough the cage wall and inserts on the indicator side of the cage, head of bolt to the inside.

A come-along from the top of the cross member to bottom of the cage corner post may be required.

For 18 ft scales a 1/2 x 3” bolt and nylon locknut is installed on the center post with the nut on the outside.
