expensive models prepared their own list of performing pre and control operations, so-
called - Check List. It can still be advantageously incorporate a list of specific control
operations on the motor and drive unit as a whole.

and smooth running in all modes of engine speed.
3. Fuel
Use unleaded gasoline with a minimum octane 95 mixed with synthetic oil designed for two-stroke
engines.
For running we recommend 1:25, after running 1:30. Run-in should take about 2 hours of operation.
We recommend Valvoline oil - SynPower 2T - Full Synthetic, Mobil 1 - Racing 2T - Full Synthetic or

26/12. For best results use Fiala propellers.
With these propellers motor should be measured on the ground to achieve optimum speed, ie
approx. 4500 - 5000 rev / min. When installing and using the propeller observe strictly all safety
recommendations propeller manufacturer. Propeller is mounted on motor by a central bolt M10x 1
and six screws around the perimeter of the flange.
5. First start of the motor

- Start the motor
If the engine can no longer run, we recommend:
- Make sure that the ignition is switched off
- Close the choke
- 3-4 times to spin the motor, in order to draw fuel
- Open the choke and set the throttle
- 1 x spin the motor
- Set a slightly increased idle speed of about 3-8% (must be tested on a specific motor)
- Turn the ignition
- Start the motor
If the engine still does not start, it is necessary to contact an authorized service center or the
manufacturer directly.
7. Running motor
Each motor is factory-tested and adjusted to the basic setting. Use a fuel with a higher ratio of oil
(see section 3 of this manual), ie. 1:25. While running is not recommended long term exceed the
motor speed 2500 / min while controlling the temperature of the engine. Do not keep a constant
speed but motor flush with the occasional addition / slow down the gas. This mode observe about
the first 30 minutes of operation. After a short time, you can gradually increase the speed up to 4000
/ min. Total time of run is about 2 hours.

condition of the spark plugs and ignition battery status.
9.1.Adjusting valve clearances –only on cold motor!
The correct valve clearance is cold engine 0.1 mm. Is set with the gauge attached and keys.
1. Remove the valve cap
2. Turn propeller to remain both valves as well ajar
3. Then turn the propeller in the same direction by one revolution
4. Adjust the valve clearance - see the following text
5. Lubricate the rocker - see section 9.2
6. Replace the valve cover
Setting procedure: loosen the nut, place the gauge between the rod and rocker arm and adjust
gradual screwing clearance so that the gauge was sliding grip. Then tighten the nut again. After
tightening recheck valve clearance. More tells you the following three photos. A system of
adjustment is a classic - cut right valve adjusts the left and vice versa.
9.2.Lubrication rockers
Always when checking / adjusting valve lash perform simultaneously lubricate the rocker. We

set to 0.4 mm. When the electrodes are burnt, replace the spark plug.
10. Carburetor
The standard motors mounted Walbro carburetor. Such carburettors are fitted along side by two
adjusting rotating needles marked H (high) and L (low). Needle labeled H is used to adjust the
carburetor / motor at maximum RPM and needle bearing L turn affects low speeds and transitions to
the midrange. Basic settings of the two needles is 2 turns, calculated from tight needles. Fine
adjustment and tuning of the engine should be performed by fitting the model.
