SF-1400 Range-General Usage Guidance

The SF-1400 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
1400 Series Hydraclamps

If you are uncertain about any element or step of this process the unit should be returned to WDS Component Parts Ltd for refurbishment.
These instructions must be read in conjunction with the drawing on page 7.

It is important that absolute cleanliness must be observed when servicing hydraulic equipment. Before commencing the procedure ensure there is no dirt on either the hand knob assembly, locknut, and bleed screw, or the area surrounding these items.

The hand knob assembly, the plunger, and the plunger seal must first be removed from the base by proceeding as follows:

• Ensure you have a clean surface of sufficient size to layout the components.
• Place the unit on it’s side with the handknob assembly uppermost. Slacken the locknut. Undo and remove handle assembly/pre-optive sleeve assembly and locknut, lay them on a clean surface.
• Remove the plunger (Note the orientation of the plunger seal, take care not to damage it, or it may damage the bore in which it is housed. The plunger has a M6 tapped hole to help remove it easily. When removed place on a clean surface. The plunger seal will be on the plunger. Check the seal for damage, replace with a new seal if any signs of wear or nicks are present.
• Now examine the bore of the body for damage. Nominal scoring or marks may be dressed out with a fine stone or wet & dry paper. Any heavy nicks or scoring will require replacement of the base.
• The unit can now be filled via the bore from which the seal has been removed using only recommended hydraulic oil. Whilst maintaining the bore in a vertical position, pour the oil slowly to minimise the amount of air trapped in the unit during filling, until the oil is a distance of 44mm (1.75”) from the outer face of the body.
• The seal kit for SF-1400 is SF-4776.
• Maintain the body in this position, note the orientation of the plunger seal on the plunger, insert the plunger and seal carefully into the hydraulic bore, taking care not to damage the seal.
• Check the hand knob assembly, the end of the adjusting screw should not project beyond the inner end of the preload sleeve. Fit the locknut onto the pre-optive sleeve. Assemble this unit to the body, screw the unit until the pre-optive sleeve pushes the plunger. Note that the pre load sleeve should be 27mm from the body. The locknut should still be in a free position. (See SF-1400M on page 7).
• Turn the HYDRACLAMP so that the bleed screw is upper most. Slacken the bleed screw approximately one complete turn. Now rotate the pre-optive sleeve slowly in a clockwise direction thus forcing oil out of the unit, past the bleed screw. Check this fluid for signs of air, when no air is visible in this fluid retighten the bleed screw. It is important that this procedure is done carefully as when the unit has been completely bled of air, the stroke for the preload sleeve should be as large as possible, (if it is insufficient, repeat the filling process). Now tighten the locknut against the body, whilst retaining the pre-optive sleeve in it’s present position.
• Rotate the handle (handwheel assembly) in a clockwise direction, to pressurise the HYDRACLAMP and check for any leaks, if any oil leaks are found take the appropriate action to cure them. If no leaks are apparent rotate the handwheel in an anti-clockwise direction to release the pressure in the unit and then check the ball arm is free to rotate. If it will not rotate this may be caused by too great a pressure being applied by the preload sleeve. To reduce the pre-optive pressure slacken off the locknut and rotate the pre-optive sleeve a small amount anti-clockwise. Retighten the locknut whilst maintaining the position of the pre-optive sleeve. If this procedure does not cure the fault then the source of the problem must be found and the fault rectified.
• Mini-booster maximum air input pressure is 5.5 bar. The seal kit for the mini booster is SF-4777.
