Thank you for purchasing the AquaCraft Nitro Hammer! This
manual  contains  the  instructions  you  need  to  safely  build,
operate  and  maintain  your  nitro  R/C  boat.  Read  over  this
manual thoroughly before operating the Nitro Hammer.

Use  care  to  avoid  touching  the  propeller  anytime  the
engine  is  running.  Pay  equally  close  attention  to  items
such as loose clothing, shirtsleeves, ties, scarves, long hair
or  anything  that  may  become  entangled  in  the  spinning
prop. If your fingers, hands, etc. come in contact with the
spinning propeller, you may be severely injured.

Because of the speed and mass of this boat, it is capable
of inflicting property damage and severe personal injury
if a collision occurs. Never run this boat in the presence
of  swimmers  or  where  the  possibility  of  collision  with
people or property exists.

This boat is controlled by radio signals, which are subject
to  possible  interference  from  other  R/C  transmitters,
paging  systems  or  other  electrical  noise.  Before  turning
your  radio  on,  make  sure  no  one  else  in  the  area  is
operating a radio on the same frequency (channel).

Model engine fuel is poisonous. Do not allow it to come
into contact with the eyes or mouth. 

Always store fuel in a

clearly marked container and out of the reach of children.

Model  engine  fuel  is  highly  flammable.  Keep  it  away
from  open  flame,  excessive  heat,  sources  of  sparks,  or
anything else that might ignite it. 

Do not smoke or allow

anyone  else  to  smoke

in  close  proximity  to  open  fuel.

Make  sure  that  fuel  lines  are  in  good  condition  so  that
fuel will not leak onto a hot engine causing a fire.

Never operate your engine in an enclosed space. Model
engines, like automobile engines, exhaust deadly carbon
monoxide. 

Run your engine only in an open area.

Model engines generate considerable heat. Do not touch any
part of your engine until it has cooled. Touching the muffler,
cylinder head, or exhaust header may result in a serious burn.

Use safety glasses when starting or running engines. The
propeller  may  throw  loose  material  such  as  sand  or
gravel into your face.

Avoid  running  the  boat  in  cold  weather.  The  hull  and
plastic  parts  can  become  brittle  at  low  temperatures.  In
addition, grease and oil become thick, causing premature
wear and poor performance.

If the buyer is not prepared to accept the liability associated
with the use of this product, the buyer is advised to return
this  kit  immediately  in  new  and  unused  condition  to  the
place of purchase.

Avoid  working  over  a  deep  pile  carpet.  If  you  drop  a
small part or screw, it will be difficult to find.

Place a mat or towel over your work surface. This will prevent
parts from rolling off and will protect the work surface.

Test fit all parts before attaching them permanently.

Repair service is available anytime.

After  the  90-day  warranty,  you  can  still  have  your  Nitro
Hammer  repaired  for  a  small  charge  by  the  experts  at
AquaCraft's authorized repair facility, 

Hobby Services
