6.3.1 Lift the load
• Close the pressure relief valve on the pump.
• Position the wedge under the load:
- Use one of the four steps of the top plate of the wedge for lifting or spreading.
- Let the load rest on the whole surface (Fig. 6) of the step.
- Let the load rest on the full width of the step.
• Operate the hand pump or foot pump to open the wedge.
6.3.2 Use the safety block
Refer to Fig. 7.
Use the safety block to underpin (secure) the load after lifting.
• Slide the safety block (2) under the load as far as possible when you have completed the lifting
action.
• Open cautiously the pressure release valve of the pump. The load will now rest on the safety block.
• Push the wedge (1) further under the load to continue lifting, if necessary. In this way, you can
create more space under the load.
6.3.3 Use the stepped block
Use the stepped block to lift the load with a larger supporting surface. By mounting this block, you can
make an extra opening of 7.5 mm.
• Attach the stepped block (Fig. 8/2) with an M6 x 10 bolt (Fig. 8/1) to the top plate.
• Make sure that the wedge is slid at least X = 15 mm (Fig. 9) under the load and that the full width of
the block is being used.
6.4 After use
6.4.1 Shut down and disconnect
• Open slowly the pressure relief valve on the pump. The pressure decreases and the load lowers.
The top plate returns to the home position by the internal spring.
• Disconnect the hydraulic hose from the tool and the pump. Refer to section 5.3.
6.4.2 Inspection
• Check the tool for completeness, leaks and damage. Do not use the tool if it leaks or is damaged
and contact the Holmatro dealer.
6.4.3 Cleaning and storage
• Clean the tool and any accessories before storage.
• Store the tool in a dry and well-ventilated area.
