Brake must not slip under loadTo adjust:
TURN nut toward spring for ... INCREASED brake capacity TURN nut away from spring for ... DECREASED brake capacity
Brake spring must be just tight enough for brake to hold load without slipping

Pioneering
Start cut down grade if possible.Slope to inside of cut. Cast material over bank.Doze bench wide enough for machines that will follow.Continue down around slope Make starting cut with a series of downhill passes if necessary.Ditching
Angle Blade - tilt blade and work with low side in ditch center.Level blade when required depth and slope is reached. Straight Blade - tilt blade to cut shallow "V" ditches.Larger ditches - work at right angle to center of ditch.Doze length of ditch to smooth sides and bottom.Backfilling
Angle Dozer - travel parallel to ditch. Straight Dozer - Push at 90° to ditch.Side By Side
Use when moving large quantities of loose material. Keep both blades close together and parallel. Remember: There is constant danger of slides when working on a high bank. Rock Removal
Straight Dozer - contact rock at one side of blade. Angle Dozer - contact rock in center of blade. Tree Removal
Cut roots on side opposite direction of fall. Cut roots on sides parallel to direction of fall. Ease into tree.Push in direction of fall with blade high.Build earth ramp if higher contact is needed. Large brush and medium size trees-contact tree 12" to 16" high.Move forward while raising blade. Removing stumps-lift blade while pushing.Brush Clearing
Lower blade a few inches into ground. Move forward.When brush is out move forward while lifting blade.Methods Of Ripper Operation
Use first speed for most ripping operations. It is better to use additional shanks, where practical, rather than to increase speed. Start with one shank. If the material is penetrated easily and breaks up satisfactorily, adding more shanks may be desirable. Cross rip only where one way ripping will not adequately loosen the formation. When ripping a scraper cut, rip in same direction that scrapers load.Rip downhill whenever possible.Operating Hints:
In most cases it is desirable to rip as deep as possible. Sometimes it is better to rip at partial depth and remove the material in its natural layers.Keep several inches of material on top of the unripped formation to cushion the machine and provide traction.When final material size must be relatively small, close spacing of passes is recommended.Packed Soil, Hard Pan, Clay, Shale or Cemented Gravel
Three shanks work well in these materials. Use as many shanks as necessary to break material to desired size without stalling or hanging up the machine.Rock with Fractures, Faults and Planes of Weakness
Use two shanks where rock breaks out in small pieces and the machine can handle the job easily. When machine begins to stall or tracks spin, use only the center shank.Solid Rock, Granite or Hard-to-Rip Material
Use one shank in tough-to-rip material or material that tends
