PT Hydraulics Australia
offers a few useful pointers about basic techniques to be employed when operating hydraulic cutters.
Using the right technique will not only help gain efficiencies but also reduce damage to the cutters.
Expose before cutting
It is important to remove interior panels from vehicle structures before operating the cutter. This will help with identifying risk zones such as SRS, high strength steel and seat belt housing among others.
Given that modern vehicles have wider and deeper pillars, it is better to cut just below or level with the seat when removing the B pillars as this option will reduce the number of cuts required, saving precious time during a rescue effort. The remaining stem of the pillar will also provide with an option for a ram, should a dash relocation technique be required.
Inadequate cutting forces
If the cutter being used is underperforming or has less capacity, the user should consider the option of cutting the B pillar high by utilising a ‘pie cut’.
Create a gap
Using spreaders, the user can create a gap around the hinges to engage the cutters, while allowing greater visibility. Users are advised not to cut blindly.
If the cutter starts to rotate during cutting, the user should reset the tool and continue the cut.
