2. CONTROLS 2.10 FOOT CONTROLS Operation of the lift cylinders and bucket tilt cylinders are controlled by foot pedals (Fig. 2.10A) connected to a hydraulic control valve. The hydraulic control valve is a series type valve which allows simultaneous use of both the lift and bucket tilt circuits. Lift – The L.H. pedal is the lift control (Fig. 2.10A). To raise the lift arms press on the heel (2) of the pedal. To lower the lift arms press on the toe (1) of the pedal. Firm pressure on the toe (1) of the pedal will lock the lift arms in float position. This allows the bucket to follow the ground as the loader moves backward. Bucket Tilt – The R.H. pedal is the bucket tilt (dump) control.
Pressing on the toe (3) of the pedal will dump the bucket. Pressing on the heel (4) of the pedal will roll the bucket back. C669 Fig. 2.10A 2. 11 HAND CONTROLS Hand controls to operate the loader’s lift arm and bucket hydraulic system as well as the loader’s travel speed and direction are available. Refer to Section 2.8 for instruction on steering controls. LIFT ARM AND BUCKET CONTROLS The right hand lever controls the bucket tilt cylinders (Fig. 2.11A). Moving the control lever to the right causes the bucket to dump. Moving the lever to the left rolls the bucket to the carry position. Moving the left hand control lever (Fig.
2.11A) to the left will cause the lift cylinders to extend, raising the loader’s lift arms. Moving the control lever to the right causes the lift cylinders to retract, lowering the lift arms. Moving the control lever to extreme right will place the lift arms in float position. This allows the bucket to follow the contour of the ground as the loader moves backward. C3020 Fig. 2.11A When the control levers are released they will automatically return to the neutral position stopping all hydraulic movement and travel speed. Before exiting the loader, lower the lift arms completely down to the frame and ground the attachment. Then shut off the engine.
Move both levers to the left and right to ensure the hydraulic controls are locked before you get out of the loader. To avoid personal injury, lower the lift arms, shut off the engine, raise the seat bar and cycle the controls to ensure they are locked. Then, unlatch the seat belt and exit the loader. Do not enter or exit with the engine running unless as specified in this manual or under specific service and backhoe operating procedures. To prevent personal injury do not operate the loader without lowering the safety bar, fastening the seat belt and keeping feet on the control pedals or cab floor.
WARNING WARNING 18 IMPORTANT Return the auxiliary hydraulic control to the neutral position when not in use.
