Wedge Spreader “CY1501”
4. START UP
1.
Connect the hose end to the pump and screw the male coupler to the other hose end and connect it to the wedge. Ensure the connections are perfectly engaged
to ensure the correct function of the system.
2.
Ensure the tool is fully retracted before inserting it between the flange faces.
3.
Remove the bolts from the flanges. Insert the wedge spreader and check the correct full engagement of the wedge spreader shoes and the grip between the tool
and the flange faces. Minimum access gat is 5 mm.
4.
Pump until the end of stoke of the tool. Maximum working pressure: 700 bar.
5.
Insert the safety block CY15B and gradually reduce the pressure on the wedge spreader.
6.
Insert the tool again and repeat previous steps until maximum flange opening possible using the safety block.
7.
To close the flange, insert the spreader at approx. 80% stroke of the tool in order to take over the load from the safety block onto the wedge spreader. Remove the
safety block one step back and reduce the pressure to let the load be taken by the next smaller step of the safety block.
8.
Repeat previous step until flange closing and replace and tighten flange bolts.
It is recommended to use two wedge spreaders in tandem. This will give an even spread to the joint. The spreaders should be set at 180°.
Never insert the fingers into the gap when the flanges are held by the spreader unless a safety block will be using.
Never hit or force the tool to create an access gap.
5. MAINTENANCE
Clean and grease the tool after its use. For that:
1.
Unscrew the screws (7, 14) and open the wedge.
2.
Clean and degrease inside surface of the stepped shoes (11), external surface of the wedge (3) and its slots.
3.
Re‐grease the same parts with quality, high pressure grease.
4.
Close the stepped shoes and torque the screws to 34 Nm.
