TO THE SLOTTED END OF THE RELEASE  PLATE. Next shake
the MICRO-BLASTER  so  that the Firing Pin extends  about 1/10
of  an  inch  from  the  tip  of  the  MICRO-BLASTER.  A  whipping
motion  seems  the  most  effective for extending  the Firing Pin.  If
the  Firing  Pin  is  not  easily  shifted,  check  for  damage  or  dirt
which may be  stopping  its free movement.  NEVER  USE YOUR
MICRO-BLASTER   IF  THE  FIRING  PIN  DOES  NOT  MOVE
FREELY. The green indicator  should  not  be  visible  through  the
countersunk hole in the side  of the MICRO-BLASTER  when  the
Firing  Pin  is  extended.    With  the  pin  extended  from  the  tip,
carefully  insert  the  tip  of  the  MICRO-BLASTER    into  the  hole
and  gently  slide  it  into  the  hole  until  it  makes  contact  with  the
cartridge  installed  in  the  previous  step.  Some  resistance  to
insertion  is  desirable  as  this  will  contribute  to  the  effectiveness
of  the  MICRO-BLASTER  in  that  the  gasses  produced  from
initiation  of  the  cartridge  will  not  easily  eject  the  MICRO-
BLASTER  from  the  hole.  To  make  sure  that  you  have  made
contact with the cartridge notice that you can now see the  green
head of the Firing  Pin through  the  countersunk  hole  in  the  side
of your MICRO-BLASTER BODY.  If you cannot see the green  it
is  very  likely  that  the  tip  of  the  MICRO-BLASTER  is  not  in
contact with the end of the cartridge. The MICRO-BLASTER  will
not  initiate  the  cartridge  if  the  tip  is  not  in  contact  with  the
cartridge.   When you can see green through the hole, the  tip of
the MICRO-BLASTER is in contact with the cartridge and  ready
to  fire.  Covering  the  masonry  or  rock  with  a  blast  mat  (ie  old
carpet  or  other  heavy  material)  is  highly  recommended  and will
avoid  damage  to  anything  in  the  immediate  area  from  flyrock.
After making sure that the  area  is  clear,  remove  the  safety  clip
and retreat to the end of the 25 foot (8 meter) release  cord.  Be
extremely  careful  to  avoid  stepping  on  or  tripping  over  the
release  cord  and  inadvertently  triggering  the  MICRO-BLASTER
as you move to the WINDER end of the Release Cord.

6.  Before  initiating  the  cartridge  again  carefully  scan  the  area
around  where  you  are  working  and  make  sure  that  no  one  has
inadvertently  entered  your  work  area.  When  you  have
determined  that  the  area  is  clear  pull  the  Release  Cord  gently
but steadily until the MICRO-BLASTER initiates the cartridge.
