MARKER-TERMINAL 5421122 - Caterpillar

1. Articulate the machine so the front wheels and the blade are in the ditch. Steer with the front wheels. 2. Keep the rear wheels on the shoulder to prevent wheel slippage in wet or soft material in the ditch. This method may be used to avoid obstructions whenever cleaning old ditches, which may have tree overhangs, rock ledges, etc.Grading on 3 to 1 Slope
Be completely familiar with the machine before operating on extreme side slopes.Never fully articulate the machine uphill on steep slopes.
On steep slopes, the machine should be operated in first gear, at a reduced engine speed.When working on slopes, use the accelerator to control the speed of the machine.
When operating on extreme slopes, use crab steering to keep the back of the grader on the downhill side of cut. Articulate the frame, to place the frame in an offset position, for maximum stability. Use crab steering when the front of the machine tends to slip due to the heavy side load on the blade.High Bank Cuts - Right Side
Be sure to ground the moldboard before retracting the centershift lock pin.
1. The road bed at the base of the cut must be uniform. 2. If the material is hard, slope the road bed slightly into the bank to keep the machine from sliding away from the bank.3. Tip the moldboard 3/4 to full position forward. 4. Move the centershift lock pin to the position shown. Move the centershift lock pin lever to the INDEX and RUN position.5. Sideshift the moldboard to the right. 6. Rotate the circle counterclockwise. Lower the left lift cylinder while the circle is turning. 7. Lower the left lift cylinder to set heel of the blade at the bottom of the slope and in line with the outer edge of the rear tire. 8. The right rear tires should be in the "V" at the base of the slope. 9. Lower the right lift cylinder to set the desired degree of bank slope. 10. Move into the cut gradually. The wheels normally should be near the vertical position.11. Lean the wheels toward the slope for a heavier cut.12. Lean the wheels away from the slope for a lighter cut.Keep the material from the slope moved to the outside of the rear wheels.The procedure shown is for the right side. Position the moldboard opposite to that shown for the left side.Extreme Side Reach
Be sure to ground the moldboard before retracting the centershift lock pin.
1. Move the centershift lock pin to the position shown. Move the centershift lock pin lever to the INDEX and RUN position. 2. Sideshift the moldboard as shown. 3. Lower the blade to the desired depth and set it at an angle to deliver the material to the side. Right side shown. For extreme left side reach, position the centershift lock pin and moldboard opposite to that shown.Ripper/Scarifier Operation - With Frame Straight
When using ripper/scarifier, the frame must be straight.
Use one to three shanks in severe conditions. Use three to
