8. Re-install the air filter assembly back onto the air filter base.
❏
9. Decal the body as shown on box.
BEFORE OPERATION:
•
Prepare only the amount of gasoline needed.
•
If the engine was just run, make sure you allow enough time
for it to cool down before you run it again. Also, wipe off any
residue the engine may have blown on the FireHammer.
•
Fuel the FireHammer with the adequate gasoline mix.
ENGINE BREAK IN:
•
To break in your FireHammer engine, you need to run the
engine for two tanks of fuel with a fuel mixture that
contains a 25:1 (4%) fuel/oil ratio (5oz. per 1 gallon).
•
Do not adjust the high-speed needle on the carburetor to
break in the engine. If you do so, carbon will accumulate
in the spark plug and making ignition difficult.
•
Do not run at full power for extended periods of time
while breaking in your engine.
•
Run the FireHammer with the body off for break in.
RUNNING THE FIREHAMMER AFTER BREAK IN:
•
Once the engine is broken in, use 40:1 (2.5%) fuel/oil mix
(3.2oz. per 1 gallon).
ENGINE ADJUSTMENTS:
•
Always make high and low speed needle adjustments
with the engine shut off.
•
Always make small adjustment to the needles to prevent
over-adjustment.
•
To lean the engine, make a clockwise adjustment to the
desired needle.
•
It is not necessary to change the needle settings if the
engine is running smoothly. Normally only the high speed
needle will need adjustment from time to time, and only
a small amount.
IDLE ADJUSTMENT:
Do not confuse the idle screw with the low speed needle. The
idle screw physically adjusts how much the carburetor valve can
close. The low speed needle adjusts the gasoline to air mixture
when the engine is running at low rpm. If your engine appears
to work correctly except that the low rpm are not as low as you
want them to be, then adjust the idle screw. If your engine
behaves erratically at low rpm, then adjust the low speed
needle. When adjusting, turn the screw about 1/8th of a turn
each time. A dirty plug will make it difficult to adjust the idle rpm.
FUELING THE FIREHAMMER
❏
1. Unscrew the fuel cap (110) from the fuel tank (116).
❏
2. Pour the proper fuel mixture into the fuel tank.
❏
3. Thread the fuel cap back into the fuel tank making sure
that the fuel cap is thoroughly tightened.
❏
4. Wipe off any fuel that may have spilled onto the
FireHammer during the fueling process with an old towel.
STARTING THE FIREHAMMER
❏
1. Turn on the transmitter and then the receiver.
❏
2. Check the throttle and steering to make sure they are
functioning properly.
❏
3. Prime the engine. Push the primer button until you start
to see fuel in it. Note: Do not press the primer after you
start to see fuel. This will flood the engine and cause it to
be hard to start.
