SF-1500 Range-General Usage Guidance

The SF-1500 range of Hydraclamps can be either hand or air operated. This allows pressure to be readily applied or released in accordance with the requirements of the load.
In the air operated version, the handle assembly is removed and replaced by a small pneumatic booster. In either case a pre-optive sleeve is provided which controls the pressure applied before locking and enables any desired degree of sustained pressure to be maintained to form a permanent partial lock if required.
Final tightening is effected by tightening the handle or applying air pressure using the foot operated switch. The normal method of use is to set the pre-optive sleeve so that the load is almost weight neutral and final tightening as above to make the unit ready for use. To do this:

1. Mount the load to the unit.
2. Fully back off the handwheel.
3. Loosen the locknut.
4. Adjust the pre-optive sleeve so that the load becomes almost weight neutral.
5. Lock the lock nut.
6. Adjust the load to the required position.
7. Tighten the handwheel (or apply air pressure by means of the foot switch).

There should be no need to apply more than hand pressure to lock the unit and the load in position.
Points to watch for during operation and use.

1. Check that there are no external leaks from:
   • Fill point/bleed point
   • Handwheel assembly
   • In the turret/ball cavity
   Any leak will result in the pre-optive sleeve having to be reset and the handwheel will have to be screwed in further to apply the same pressure as it will have lost some volume of oil. This can be topped up by following the filling and bleeding instructions but be aware that a leak is usually an indication that a seal is not performing as it should and this needs to be investigated and repaired to prevent failure of the unit.
2. If the handwheel has to be screwed in further than normal, then oil has been lost from the unit and action as above should be taken.
3. Be aware that the unit operates by the use of friction and on no account should oil, grease or dirt be allowed to enter the turret/ball cavity as this may seriously affect the performance of the unit.

Filling & Bleeding Instructions for
1500 Series Hydraclamps

It is preferable to fill and/or bleed the hydraclamp when it is in a horizontal position. Whilst the procedure can be carried out with the unit in a vertical position all of the air will not necessarily be expelled from the unit. ISO 68 hydraulic or equivalent must be used for filling and it is also recommended that a hand pump (type SF-0E00691) be used to assist the operation of filling and bleeding.

1. On manual units, set the handwheel to the 82mm dimension (figure 1) slacken the locknut & set the pre load sleeve to 28.5mm dimension.
2. On hydraulic units set the unit to the 33mm dimension (figure 2).
3. Using a spanner to prevent the fill/bleed adaptor which is nearest the handwheel from rotating, undo and remove the acorn nut from it together with the bonded washer. Do not undo the second acorn nut at this stage.
4. Connect a hand pump to the adaptor using a suitable length of 1/8”BSP flexible hydraulic hose and commence pumping. When the relief valve setting of the pump has been reached open the release valve on the pump.
5. Undo the second acorn nut whilst preventing its adaptor from rotating and remove the
   acorn nut.
6. Close the release valve at the pump and commence pumping, continue to pump until the fluid coming out of the hydraclamp is completely free of air buddles, then refit the acorn nut to this adaptor and tighten it to seal off the bonded washer.
7. Remove the flexible hose from the other adaptor and replace the bonded washer together with the acorn nut. Tighten the acorn nut to seal off at the bonded washer. NOTE: - if the unit is mounted vertically or on its side, the hand pump should be connected to whichever is then the lower adaptor and fluid bled from the other. (Hence instruction 2 should be modified to suit these conditions.

If you are uncertain about any element or step of this process the unit should be returned to WDS Component Parts Ltd for refurbishment.
