watching roof movement.
9. Cease pumping when the roof in a position where it can be pulled back with ropes attached to the
Apost (may require adjustment and additional extensions before lift is completed)
10. Secure the roof to minimize any movement.
H. Forcing Door
1. Forcing a door is best accomplished with both wedgie and spreader and two pumps.
2. Due to strength of locking mechanism on most modern automobiles, forcing of door should be
undertaken at hinges rather than lock.
3. Use a haligan bar and axe to make purchase point in opening between door and fender by forcing
adz (wedge) end of the haligan bar in opening and prying up or down to widening the opening.
4. Use wedgie to further widen opening and expose hinges.
5. As opening is widened, spreader can be used to force door at hinged side.
6. Hold both pumps with the hose pointing downward and pumping the squeezing the handle against
the pump (this reduces the chance for overpowering the pump).
7. Reposition either wedgie or spreader as needed. Forcing should be done as close to hinge as
8. Be cautious not to overpower the wedgie or spreader. The porto-power may not have sufficient
strength to force the door open.
9. If door latch and locking mechanism can be operated, porto-power can be operated at lock side
to force door (porto-power not strong enough to overcome lock).
I. Displacing Front Seat
1. Attached serrated saddle to bottom of cylinder.
2. Attach female to male adapter to plunger.
3. Measure distance between bottom of A-column near rocker panel and seat bracket and insert
necessary extensions using lock-on connectors, as needed.
4. Put 90-degree V-wedge on extension to secure to seat bracket; place wedge against upper portion
of seat bracket.
5. Make sure ram is pushing at right angle to seat bracket to minimize ram slipping as pressure is
6. Hold pump in hands with hose downward, close relief valve, and begin pumping slowly while
watching seat movement.
7. Cease pumping when sufficient space has been achieved for the rescue.
8. Alternative method is to pull seat from behind using the pulling capability of ram.
9. Place the single chain plate on outside cylinder threading.
10. Place double chain plate on plunger.
11. Pass chain under seat and secure it to forward portion of both seat brackets using caution to
make sure that chain is attached to portion of bracket attached to seat rather than portion
attached to floor. This is best accomplished with two short pieces of chain.
12. Pass chain through the holes on double chain plate and attach in respective slots on single chain
13. Using another piece of chain, wrap chain around a frame member under vehicle.
14. Pass chain back to ram and secure in respective slots in double chain plate.
15. Take up slack in chains and make necessary adjustments so that pulls evenly.
16. Hold pump in hands with hose downward, close relief valve, and begin pumping slowly while
watching seat movement. Movement of plunger pulls chain rather than pushes.
17. Be aware that movement of seat will probably be sudden rather than gradual. Patient should have
been boarded and collared prior to beginning operation.
J. Widening Door Opening
1. Operation involves pulling door away from opening to make opening for patient removal wider.
2. Place single chain plate on outside cylinder threading.
3. Place double chain plate on plunger.
4. Pass chain around door already been forced open and secure so that it will not slip as door is
pulled. This is best accomplished with single piece of chain.
