12 Y- 5. Y- 5. Adjustment and checks This section covers the procedures to be applied when performing adjustments and checks in areas other than the pressure and electric areas, which have been covered in the preceding sections. 4) After bleeding the master cylinder is completed, proceed with the swing driving unit. Bleed the swing driving unit in the same manner as for the master cylinder. Swing system 1. Master cylinder mounting and adjusting procedure There must be a play of about 0.5 mm between the push rod and piston when the swing brake lever is free. Adjusting nut Push rod Master cylinder 3. Swing circuit bleeding procedure After replacing the oil in the hydraulic oil tank or removing the pump or equipment on the P3 discharge side (manual control valve for outrigger, rotary joint, etc.), bleed the swing circuit of air as follows. 2. Swing brake circuit bleeding procedure 1) Start the engine to run the pump. 1) Remove the plug of the VT port on the manual control valve (for swing), and make the supply valve normally open. Under such a condition, start the engine and bleed the circuit about one minute at idle. After bleeding is completed, stop the engine and plug the VT port. 2) Insert a vinyl hose in the bleeder screw on the master cylinder. VT port 3) Pull the swing brake open the bleeder screw, and close the bleeder screw before releasing the swing brake. Repeat this procedure until discharged fluid contains no more air bubbles. Once no air bubbles are visible, close the bleeder screw while the fluid is still flowing out. 2) Run the engine and make sure that the pressure builds up in the accumulator. If the pressure does not build up, repeat the step 1). 8 Y E

Foot brake cylinder Brake pedal 1) Set the drum lock lever to the lock position. 2) Set the clutch lever to the Free position. 1) Adjust the rod of the master cylinder so that the angle between the brake pedal and the floor board is about 20 when the brake pedal is not depressed. NOTICE Manually move and release the pedal and make sure that the piston of the master cylinder is completely returned. 3) Depress the brake pedal and open the bleeder screw on the brake cylinder, and close the screw before releasing the brake pedal. Repeat this procedure until discharged brake fluid contains no air bubbles. Once no air bubbles are visible, close the bleeder screw while the fluid is still flowing out. NOTICE Pay attention to the fluid level in the brake fluid reservoir. 2) Turn bolt (a) until the clearance [A] is eliminated when the brake pedal is not depressed. 3) Depress the pedal and adjust the bolt (b) so that the stroke of the master cylinder becomes 24 mm. 2. Winch brake circuit bleeding procedure A. Automatic brake cylinder 1) Set the drum lock lever to the lock position. 2) Insert a vinyl hose in the bleeder screw on the brake cylinder. 3) Set the clutch lever to the Free position. 4) Open the bleeder screw to bleed the hydraulic system until discharged fluid contains no air bubbles. Once no air bubbles are visible, close the bleeder screw while the fluid is still flowing out. 3. Winch brake adjusting procedure 1) Turn the synchronizing bolt (b) until [L] becomes 18.0 mm. 2) With the clutch lever in the FREE position and the drum lock lever in the LOCK position, set the winch control lever to the neutral position. 3) Use a wrench to tentatively tighten the stroke adjustment nut (a) until the clearance between the drum and shoe is eliminated. (This can be known as it becomes hard to turn the wrench.) 4) Tighten the synchronizing bolt (b) until it becomes hard to turn the wrench so that Y becomes 0 when the clearance X is 0. Secure the bolt with a nut and lock it with wire to prevent it from loosening. Y E

14 Y- 5. Y- 5. Adjustment and checks NOTICE Make sure that the dimension L is within the range of 15.0±2.0 mm. 5) Engage the clutch and loosen the stroke adjustment nut (a) until X becomes 2.5 to 3.0 mm. 9) After completing the adjustment of the clearances A and B, turn the slinging bolt and the retaining bolt to get a uniform clearance between the brake band and drum. Check that there is no clearance at Z area shown in the figure at the step 5) when the clutch is in the FREE position. Slinging bolt NOTICE Before tightening the nut (a) for adjustment, set the drum lock lever to the lock position and the clutch lever to the FREE position. Stroke adjustment nut (a) Retaining bolt 10) After the adjustment in the step 9) is completed, reeve the rope for the maximum allowable number of turns and raise the boom to the maximum angle, then check that the hook can descend quickly. Synchronizing bolt (b) Safety wire 11) Hoist a load equivalent to N times (N: number of turns of rope) the maximum allowable load per rope and make sure that no slip occurs between the brake band and drum when the winch control lever is set to the neutral position. NOTICE The maximum allowable load per rope is described in the Rated lifting capacity nameplate. Never lift a load exceeding the rated lifting capacity. 12) After adjusting the brake band, put a label so that the righthand edge of the marker lies on the black line. 6) After the above-mentioned adjustment procedure is completed, return the clutch to the FREE position and the drum lock lever to the LOCK position, and then set the winch control lever to the neutral position. Red Black line 7) Turn bolt (c) until the clearance A becomes 0.4 to 0.5 mm. 8) Turn bolt (d) until the clearance B becomes 0.4 to 0.5 mm. Marker Blue NOTICE Be careful not to over tighten the bolt (d), or there is a possibility that lowering operation at high speed may not be achieved when loaded. (If not loaded, lowering operations can be done at high speed.) 4. Clutch cylinder bleeding procedure 1) Rotate the drum until the bleeder screw is located at the top. 2) With the winch control lever in the neutral position, set the clutch lever to ON and open the bleeder screw to bleed the clutch of air. 1 0 Y E

Winch clutch adjusting procedure 1) Set the drum lock lever to the lock position, and the clutch lever to the "FREE" position. 1) Depress the accelerator pedal and open the bleeder screw (located on the right side of the rotary joint) to bleed the circuit, and close the bleeder screw before releasing the accelerator pedal. Repeat this procedure until discharged fluid contains no air bubbles. Once no air bubbles are visible, close the bleeder screw while the fluid is still flowing out. 2) Turn the adjusting nut on the wheel cylinder in the direction of the arrow to expanding side until it cannot turn any more. Then, turn the adjusting nut to the retracting side until the clearance between the drum and the clutch shoe is adjusted to mm. (Inside of swing table) [Reference] Returning for 4 scales results in a clearance of about 0.26 mm. 2) Also bleed the control cylinder of air in the same manner as mentioned in the step 1). Bleeder screw 6. Accumulator pressure checking procedure for nitrogen gas (N2) 1) Set the drum lock lever to the lock position. Control cylinder 2) With the engine stopped, watch the pressure gauge while moving the clutch lever between "ON" and "FREE" repeatedly. First, the pressure gauge reading will drop gradually, and then it will drop rapidly from a certain pressure level. The pressure from which the reading drops rapidly is the charged pressure of the nitrogen gas (N2) in the accumulator. (Frame inside) Slowly Charged gas pressure Suddenly 11 Y E

Accelerator (pump speed) adjustment procedure 1) Adjust the angle of the accelerator pedal θ to degree (approx. 105 mm in terms of the dimension A) with the push rod and lock the rod with the nut (a). 3) Set the rotational speed when Outrigger is operated according to the following points. Operate Outrigger and air cylinder K, and adjust with bolt J to become Outrigger pump rotation speed. Master cylinder Nut (a) Accelerator pedal Bolt (b) Push rod 2) Adjustment of control cylinder surroundings Stopper for prevention over-rotation of engine (Maker set, adjustment is unnecessary. ) Crane idle speed set bolt Bolt Lever Engine IDL Engine MAX Bolt Bolt (in side) (out side) Stopper bolt when MAX.) Air cylinder Adjust part A nut, and adjust the distance between the cylinder installation bolt and the pin center to 106 ± 1 mm. At this time, confirm there is a space in part B. (Refer to figure in the preceding clause. ) Adjust it by the material 8 rod so that cylinder rod and pin space C may become 1 mm while idling. Operate the accelerator pedal in the crane cab, and adjust for lever E to return completely with bolt H. Adjust for lever E to hit bolt I in the stroke end of engine rotation MAX. The rotatin speed depends on the pump rotation speed in chapter Y. 1 2 Y E
