4. Rotate the choke lever to the closed position.
❏
5. Tug on the recoil until the engine starts. (The engine
should start after a few pulls). It may be necessary to slightly
open the throttle to get the engine to start.
❏
6. Once the engine starts, return the throttle to neutral
and open the choke back up. Note: If you do not open the
choke after the engine starts, it will probably die quickly.
SHUTTING THE FIREHAMMER OFF
To stop the engine press the red shut off switch on the
engine. We recommend that you familiarize yourself with the
switch and what the easiest way is to get to it with the body
on. This way you are not fumbling around to find it in case of
an emergency.
FAIL SAFE SET-UP
The fail safe is designed with a signal failsafe and a battery
failsafe. If the receiver loses contact with the transmitter, the
failsafe will set the throttle to the designated position and the
red LED will be constantly lit. If the battery goes below the
preset voltage, the failsafe will set the throttle to the designated
position and the red LED will be constant and the green LED
will flash. If this occurs, shut the FireHammer off and recharge
the receiver battery before running the model again.
The fail safe should be set from the factory, but we recommend
that you double check it before running the FireHammer.
❏
1. Check that the fail safe is functioning properly before
starting the engine.
❏
2. With the receiver on, advance your throttle on the
transmitter. Then shut off the transmitter and see if the
throttle servo moves to the desired position (idle).
❏
3. Turn on the radio system and make sure the throttle is
positioned at idle. Press and hold the “SET” button for
2 seconds.
SPARK PLUG
The recommended spark plug is a DuraTrax NGK CMR 7H
Spark Plug (DTXG3100). To avoid improper operation or
possible engine damage, do not use any other type of spark
plugs. The plug gap should be .025" to .030" (if the plug gap
is incorrect, adjust it with a spark plug gapping tool, wash it
with gasoline and allow it to dry completely before you
reinstall the plug into the engine).
BEFORE EACH RUN
❏
1.Check to make sure that all screws are tight and there
are not any screws missing.
❏
2.Check to make sure that the transmitter and receiver
batteries are not low.
❏
3.Check to make sure that all of the moving parts of the
FireHammer move freely and do not bind.
❏
4.Check for broken or damaged parts. Replace any broken
or damaged parts before running the FireHammer.
Running of the FireHammer with broken or damaged
parts could result in damage to other parts.
❏
5.Check to make sure that all wires are properly connected
and secure.
AFTER EACH RUN
❏
1. Clean any large globs of dirt or debris from the chassis
and moving parts.
❏
2. Drain any remaining gas from the tank.
❏
3. Check for any broken or damaged parts. This way
parts may be replaced before the next run.
AFTER EVERY 10 RUNS
❏
1. Check to make sure that the bearings are free of dirt
and debris and roll smoothly.
❏
2. Check the shocks for oil leakage. If the shocks have
leaked any shock fluid out, you should properly refill
the shocks for best performance.
❏
3. Make sure the servo saver is free-moving and does
not bind. This will help prevent stripping of the servo
during running. Clean as needed.
❏
4. Check for proper gear mesh between the spur and
pinion gear.
