Training Bulletin 067- Holmatro Rescue Tool

Question 1

Both power units utilize a two-stage pump design capable of producing _____ psi. Initial extrication operations will only require use of the first stage pump, which is near _____ psi. When an operation requires stronger tool forces, the second stage will “kick in” which can increase the hydraulic pressure up to _____ psi. This “change over” to the second stage can be recognized by a momentary “stalling” of movement of the tool followed by a continued movement in the direction selected.
