7.  Never solder a wire or anything else directly to the cell case, as this may damage 

the pressure valve. 

8. 

Warning

Never  dispose  of  faulty  or  exhausted  NiMH  batteries  in  a  fire,  as  they  may  ex-
plode.  Don’t  discard  them  in  the  household  rubbish,  as  they  constitute  toxic 
waste and require special treatment. Take them to your local toxic waste collec-
tion  point  (ask  your  local  council  for  details).  It  costs  nothing  to  dispose  of  ex-
hausted cells properly, and helps preserve a clean environment, as most of the 
materials can be recycled. 

 
Flying the model 

Never fly your ASW 28 in a nature reserve or any other protected site. Please don’t 
disturb the animals and plants which live in the countryside. 
Trees  and  bushes  are  the  natural  habitat  of  many  birds,  and  also  serve  as  nesting 
sites and general protection for them. 
 

Important safety notes 

You have acquired a kit which can be assembled into a fully working RC model when 
fitted  out  with  suitable  accessories.  However,  we  as  manufacturers  have  no  control 
over  the  way  you  build  and fly  your  RC  model  aircraft,  nor  how  you  install,  operate 
and maintain the associated components, and for this reason we are obliged to deny 
all  liability  for  loss,  damage  or  costs  which  are  incurred  due  to  the  incompetent  or 
incorrect use and operation of our products, or which are connected with such opera-
tion  in  any  way.  Unless  otherwise  prescribed  by  binding  law,  the  obligation  of  the 
GRAUPNER  company  to  pay  compensation,  regardless  of  the  legal  argument  em-
ployed, is excluded. This includes personal injury, death, damage to buildings, dam-
age due to loss of business or turnover, interruption of business or other direct or in-
direct consequent damage whose root cause was the operation of the model. 
The  total  liability  in  all  cases  is  limited  to  the  amount  of  money  which  you  actually 
paid for this model. 
 
This model aeroplane is built and flown at the sole and express responsibility of the 
operator. The only way to avoid injury to persons and damage to property is to han-
dle and operate the model with the greatest care and consideration at all times. 
 

Before  you  fly  the  model  for  the  first  time  it  is  essential  to  take  out  a  special 
insurance policy designed to cover modelling risks. 
These  safety  notes  should  be  kept  in  a  safe  place.  If  you  ever  dispose  of  the 
model, be sure to pass them on to the new owner. 

 
 
Manufacturer’s declaration: 
 
If material defects or manufacturing faults should arise in a product distributed by us 
in the Federal Republic of Germany and purchased by a consumer (§ 13 BGB), we, 
Graupner  GmbH  &  Co.  KG,  D-73230  Kirchheim/Teck,  Germany,  acknowledge  the 
obligation to correct those defects within the limitations described below.
