    Introduction to the Handbook This handbook provides the information for the operation, adjustment and maintenance of your Standen Megastar Gen-2. To enable you to achieve the best results from the machine, the manufacturer recommends that you read the handbook thoroughly prior to using the machine for the first time.

  • Page 7: Replacement Parts

    Section 3 of this handbook contains lists of spare parts available through your Standen Agents. Each illustration shows a complete unit or assembly in exploded form. Standen's policy of continual product development means that components or even complete assemblies are redesigned from time to time.

    100 ltr/min (For flows greater than 100 ltr/min consult your officially appointed Standen dealer) There must no restriction in this return oil. Ensure that there is a full flow return, or even better return straight back into the tractor gearbox. Consult your tractor handbook or dealer for further information.

  • Page 15: Operation

    Control for the major functions of the Megastar Gen-2 are provided electronically by the switches mounted on the control box. The function of each switch is listed below.
  • Page 16 1.11 OPERATION Axle Steering The axle steer switch manually steers the machine wheels left/right. The auto-centre button when pressed operates the self-centring circuit to automatically set the wheels to the straight-ahead position. Only operate the steering while the machine is moving or some of the steering components may be damaged.

    OPERATION 1.12 Vari-Flow Web (optional) The push button starts/stops the vari-web. The LED is illuminated when the unit is running. The dial increases/decreases the speed of the web. Turn the dial clockwise to increase or anticlockwise to decrease the speed. Machine Wheel Settings The machine wheels must be set for work in a specific bed width.
  • Page 18 1.13 OPERATION Release the track rod locking bolts (item 1, fig 6) and remove the flange plate mounting bolts (item 3, fig 5 & item 2, fig 6). Using lifting equipment, carefully slide the leg pillar to the required position. Refit the mounting bolts (item 3, fig 5 & item 2, fig 6) through the relevant hole in the flange plates.

  • Page 19: Manual/Automatic Depth Control

    OPERATION 1.14 Manual/Automatic Depth Control Manual/automatic depth control ensures an even depth of soil in the finished bed. The depth roller (item 1, fig 8) runs on top of the preformed bed following the contours. On machines with manual depth control a turnbuckle is fitted between the chassis and depth roller frame.

    1.15 OPERATION The disc scrapers (item 3 fig 9) will need to be adjusted to suit the new disc position. To do this, slacken the scraper bracket bolts (item 4 fig 9) and reposition the scraper until just clear of the disc surface and retighten. As the scraper wears it can be adjusted closer to the disc by slackening the bolts (item 5 fig 9).

  • Page 21: Boulder Box

    OPERATION 1.16 Never attempt to manually adjust the clod mat angle while the drive belts and pulleys are in motion. Boulder Box (optional) The rear boulder box is recommended in conditions where many large stones and boulders are encountered and it is advisable to remove them from the field rather than leave them in the trenches between the formed beds.

    1.19 OPERATION IN THE FIELD Starting Off Your Machine Before commencing work, whether starting off a new machine or starting work in a new field, it is advisable to carry out the following checks. Is the machine connected correctly to the tractor ? Is the front end of the machine set correctly for the bed width being lifted ? Are the wheel settings correct on both machine and tractor ? Is the transport lock valve on the depth ram in the open working position ?

  • Page 25: Star Spacing

    Separation is a function of star spacing and star speed. Normal star spacing for the Megastar Gen-2 is one spacer for de-stoning and three spacers for de-clodding. Each machine can be converted to the other by changing the star spacing or by fitting alternative, ready built-up shaft assemblies.

    Slide the two halves in and out several times to ensure that they slide easily and that the grease has spread around the shaft tubes. Use only the BP lubricants recommended by Standen or an exact equivalent recommended by your lubricant supplier.

  • Page 28: Drive Belt Maintenance

    1.23 MAINTENANCE Drive Belt Maintenance As a guide, correct belt tension is achieved when, at a distance half way between the furthest spaced pulleys, the belt can be twisted approximately 45° . The LH and RH input belts should be adjusted first (see page 1.29). Ensure alignment by measuring the distance between the pulley centres.

  • Page 29: Residual Hydraulic Pressure Dump Procedure

    MAINTENANCE 1.24 As the tractor supplies the oil for the machine’s hydraulics, ensure that the tractor hydraulic system is serviced in accordance with the manufacturer's recommendations to prevent any contamination of the machine’s system. To extend the life of the hydraulic components it is important to monitor the condition of the hydraulic oil.

    1.25 MAINTENANCE Testing the Auto-Depth Control Circuit Uneven share depth operation. When share is in the fully raised position and the auto-depth function is selected the drawbar depth ram does not operate, though it does operate in manual mode. Check the setting of the proximity sensors (see proximity sensor adjustment).

  • Page 31: Proximity Sensor Adjustment

    MAINTENANCE 1.26 Proximity Sensor Adjustment Proximity sensors are used in the auto-depth control circuit and the axle self-centring circuit. The sensors are factory set and in normal circumstances should not require any adjustment. Should it be necessary to readjust, then the following settings should be obtained (see figure 19).

  • Page 32: Daily Maintenance

    1.27 MAINTENANCE Daily Maintenance During the working season the following daily maintenance should be carried out. Check all covers and guards are in position, free from damage, and all retaining latches and hinges are in place and operative. Repair or replace any found to be defective before operating the machine.

  • Page 33: Out Of Season Storage

    Inspect wheel bearings and check for excessive wear, replace as necessary. Re-pack with fresh grease on re-assembly. Replace pressure filter element. Use only genuine Standen replacement parts. THIS IS NOT A WASHABLE ELEMENT. If a high water content becomes apparent or a cloudiness in the hydraulic oil, the oil should be changed.
