Application

The SAND TRAK Model ST1-075A la wasdeveloped to use as an accessory attachment toexpand the versatility of the Military SmallEmplacement Excavator (SEE Tractor)

The attachment is used instead of the SEETractors normal 3/4 yard loader bucket. Thesandbagger attachment, following initial installationof the quick disconnects kits onto the excavatorattachment, is easily installed and/or removedwithin fifteen minutes.

The sandbagger attachment may be maintained onthe host vehicle for movement of granularmaterials or for filling sandbags.

The sandbagger is designed for use with “A” grade(3/4 inch minus) sand and gravel or smaller. Thesandbagger was not designed for material with ahigh clay content or large pieces of frozenmaterial.

The sandbagger screen will not permit gravel orrocks through the screen in excess of 1-3/4 inch insize. Material having excessive amounts of 1-3/4inch material clay or debris will cause the screen toclog rapidly, requiring that the sandbagger screensbe cleaned. (See section on cleaning underStarting and Operating).

Filling sandbags requires one person to hold bagsfor filling and a second person to poerate the hostvehicle’s excavator boom or bucket functioncontrol. A mirror is utilized by the operator to seethe person filling bags for start and stop signals. Equipment Considerations

DO NOT operate in REVERSE direction inexcess of momentary movement as this maycause damage to the motor housing seal andrubber bellows.

Variations In Sand

There are many variations in sand, from course tovery fine. With these variations sand changesconsistency when dry or wet. Sand also changesdramatically in weight from dry to wet.

The sandbagger design permits operation withmost types of sand; however, due to sand moisturecontent, and with travel, which causes packingwithin the bucket, sand or other materials will resistflow by standing vertically or tunnelling around theauger.

The above variance in conditions will resistemptying of the front and/or back areas in thebucket. As an aid to assist in emptying the bucket,the operator should raise the attachment and tilt itback and forth to dislodge the sand pockets. Thesafety stand must be removed prior to tilting.

A stick or similar object must NEVER be usedto dislodge sand while operating thesandbagger. Use of a stick may causepersonal injury and/or damage to thesandbagger mechanism.

Stalled condition

Should the sandbagger stall, due to a rock ordebris becoming jammed in the auger or screen, ordue to very wet sand having been compacted as aresult of travel, the control function may bemomentarily reversed. Should the stalledcondition not clear by momentary reversal, it willbe necessary to dump the sand out of bucket todetermine the cause.

! Caution

! Warning

�� ST1-075A Ia 12/98

Due to clay, fines and stones within sand it will benecessary to clean the sandbagger to obtain goodflow.

Stones: If sand has stones larger than 1-3/4 inches, the screens will stopentry of these stones into theauger area. As a result the dumpbody should be checked for largestones and or debris betweenloads.

Clay or Fines: When sand is wet and containsclay and/or fines, the material willbuild on screens and auger flightwhich reduces sand flow.

Sandbagger should be periodicallychecked for this condition. Shouldthis condition exist it will benecessary to wash or clean thesandbagger screens to removebuild up.

Sand is corrosive and therefore it is important thatthe sandbagger be kept clean. It is recommendedthat the sandbagger be cleaned (washed) at theend of each shift and before storing. It may alsobe necessary to wash the sandbagger during ashift to clean the screen or auger.

To clean:

• empty all sand from bucket

• shake bucket forward - run sandbagger

• tilt bucket rearward - shake and runsandbagger

• repeat steps above, and wash thoroughly

• Remove safety stand and store

• lower the bucket until resting on the ground

• ensure that the sandbagger control (boomfunction) is in neutral

• set host vehicle brakes

• stop engine

• unbuckle the seat belt, and

• exit the host vehicle using the hand holds

When old shaker bearings are reused surfacegrind the spacer ring (item 9) equal to the endplay plus .002 inch determined at disassembly(see step 2 in disassembly) e.g. for .005 inchend play plus .002 for preload remove .007inch from spacer with surface grinder. Newbearing sets are supplied with a new spacerring as a kit.

2. Torque the lock nut (item 15) to 100-150 lb/ft.Sockets are available for use with a torquewrench. An adjustable spanner wrench with anextension applying the force required relativeto wrench and extension length may also beused, eg force (125 lbs) x length (1 ft) = 125 lb/ft.

3. Torque bolt (item 1) to 100 lb/ft.

4. Torque six socket head capscrews (item 20) to100 lb/ft.

5. After torquing six socket head capscrews,install shim stacks which were removed (item21).

NOTE: Shim stack must fill complete spacebetween modular housing and frame to within .010inch before tightening through bolts and nuts (item22 & 26) to 40 lb-ft.

6. The flow control valve is normally set atadjustment point 6 for proper operating sped(Figure 14, item 7).

7. Auger speed of 240 to 260 rpm must bechecked with sandbagger on host vehicle.Higher number on flow control increases speedand lower number reduces speed.
