Thank you for purchasing the DuraTrax FireHammer. This
manual contains the instructions you need to build, operate
and maintain your new, gas-powered R/C buggy. Read
over this manual thoroughly before building or operating
the FireHammer.

When the safety precautions are followed, the FireHammer
will provide years of enjoyment.Use care and good sense at
all times when operating this radio controlled buggy. Failure
to use this vehicle in a safe, sensible manner can result in
injury or damage to property.You and you alone must insure
that the instructions are carefully followed and all safety
precautions are obeyed.

•

Do not operate the FireHammer near people.Spectators
should be behind the driver or at a safe distance away
from the vehicle.

•

Do not leave the charger unattended during charging. If
the battery or charger becomes hot at any time,
disconnect the battery from the charger immediately!
Failure to do so may cause permanent damage to the
charger and battery and may cause bodily harm.

•

Do not allow the radio equipment to come into contact
with moisture. Water can cause the electronics to short
out and can cause permanent damage.

•

Always turn on the transmitter before turning on the
receiver. Before turning on your radio, check to make
sure that no one else is running on the same frequency
as your FireHammer.

The engine is under a limited warranty for 3 years. DuraTrax
warrants this engine to be free from defects in materials and
workmanship for a period of three years from the date of
purchase. During that period, DuraTrax will, at its option,
repair or replace without service charge any product deemed
defective due to those causes .Y ou will be required to pro vide
proof of purchase date (receipt or invoice).

This warranty does not cover damage caused by crash,
abuse, misuse, alterations or accident. Damaged caused by
customer disassembly, tampering, use of substandard fuel,
use of incorrect accessories (spark plug, etc) or any use of the
engine for which it is not specifically intended will automatically
void the warranty of the engine. If there is damage resulting
from these causes within the stated warranty period, DuraTrax
will, at its option, repair or replace it for a service charge not
greater than 50% of the current retail list value. Be sure to
include your daytime telephone number and e-mail address in

•

If the vehicle is not going to be used for a month or so,
the fuel should be drained from the tank and then the
engine run until all excess fuel is used.Leaving fuel in the
vehicle for extended periods of time can cause
premature wear to parts.

•

poor ventilation.

•

Gasoline is extremely flammable.Keep it away from open
flame, excessive heat or sparks. Do not smoke while
operating the FireHammer.

•

used for any other purpose.

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