3.3 ASSEMBLY OF SECONDARY COMPONENTS
3.3.1 SPECIAL ASSEMBLY INSTRUCTIONS
Engine SKY100 is more complex than other models and a greater experience is
therefore required to assemble its components and specifically its internal ones. As
the engine is liquid cooled, the assembly of the components that use the radiator's
coolant requires the implementation of specific tasks that only a skilled mechanics is
able to carry out.
Therefore, all users who are not specifically skilled or trained to perform these
operations SHOULD NOT TOUCH THE ENGINE EXCEPT FOR ORDINARY
MAINTENANCE OPERATIONS, WHICH SHOULD BE PERFORMED FOLLOWING
THE DETAILED INSTRUCTIONS SPECIFIED BELOW. DO NOT IMPROVISE OR
ATTEMPT TO MAKE UNAUTHORIZED CHANGES THAT COULD DAMAGE THE

4.0 MAINTENANCE
THIS CHAPTER CONTAINS VERY IMPORTANT INFORMATION. IN ORDER TO
ENHANCE THE LIFE OF YOUR ENGINE AND PREVENTING PROBLEMS CAUSED
BY WEAR, IT IS ESSENTIAL TO CAREFULLY READ ALL THE WARNINGS AND
DATA ON SCHEDULES, AND FOLLOW ALL THE INSTRUCTIONS PROVIDED.
IT IS USEFUL TO REMEMBER THAT DAMAGE ORIGINATING FROM AN
INSUFFICIENT MAINTENANCE ARE NOT COVERED BY THE WARRANTY.
4.1 CLEANING
SKY100 engines do not require specific cleaning operations. However, when
performing this operation, always remember not to use corrosive solvents on the
external or internal parts of the engine.
ALWAYS KEEP THE INTERNAL PART OF THE ENGINE CLEAN TO PREVENT
RESIDUALS FROM ENTERING THE INTERIOR OF THE CYLINDER OR, WORST
STILL, THE GUARD AND CAUSING THE SEIZURE OF THE ENGINE.
✴ When using a filter box, always remember to disassemble it and wash the internal
filter with water and a degreasing detergent after approximately 100 hours of flight.
Cleaning the muffler does not improve the performance of the engine, but only the
quality and quantity of exhaust emissions. Customers who prefer not to hear so much
noise while flying should carry out the maintenance operations described in the
chapter above with a frequency of at least 50 hours of flight for an optimum operation
of the muffler.
4.2 TOPPING UP LIQUIDS
The only liquids that need replacing are:
RADIATOR COOLAN THE LEVEL OF THE RADIATOR COOLANT MUST BE
INSPECTED APPROXIMATELY AFTER 10 HOURS OF FLIGHT BY PERFORMING
THE FOLLOWING OPERATIONS:
1. Loosen the RADIATOR CAP.
2. Verify that the liquid inside the radiator reaches the side nut next to the cap.
3. If the liquid level is below the indicator, top up the radiator coolant as specified
above.
4. When replacing the whole amount of coolant, always remember not to exceed the
amount of 700 ml:
- 600 ml directly in the radiator
- 100 ml in the recovery tank
ATTENTION!
COOLANT MUST ALWAYS BE TOPPED UP WHEN
THE ENGINE IS COLD!!!
WHEN PERFORMING THIS OPERATION, ALWAYS
REMEMBER TO POUR THE LIQUID INTO THE
RADIATOR AND NOT INTO THE SMALL CONTAINER,
AS THE LATTER IS DESIGNED TO BE USED TO
COLLECT THE COOLANT IN EXCESS, NOT TO FILL
THE RADIATOR. THE LIQUID IN EXCESS MAY EXIT
FROM THE SMALL TANK.
IF LEAKS ARE VISIBLE, ALWAYS THOROUGHLY
CHECK THE SMALL TANK AND VERIFY THAT THE
COOLANT DOES NOT EXCEED THE
RECOMMENDED LEVEL.
THE SMALL TANK MUST BE FILLED UP TO THE
INDICATOR WITH THE BLACK "MAX" WORD
SITUATED ON THE EXTERNAL SIDE, AS SHOWN IN
THE PHOTO.
ALWAYS REMEMBER NOT TO FILL THE SMALL
TANK ABOVE THE MAXIMUM LEVEL AS THIS
COULD CAUSE LEAKS.
REDUCTION GEAR OIL:
1. REGULARLY INSPECT THE OIL LEVEL IN THE REDUCTION GEAR
USING THE BUSHING ON THE FRONT SIDE.
2. REPLACE THE WHOLE AMOUNT OF OIL AFTER APPROXIMATELY
100 HOURS OR IF YOU NOTICE THAT THE BUSHING IS PLACED
IN PERFECT VERTICAL POSITION.
3. OPEN THE BUSHING AND INSERT 30 ml OF SYNTHETIC OIL OF GEARS.
✴ Our technician recommend Bardahl SAE 75W-90 synthetic oil
4.3 ADJUSTMENTS
The only adjustment that may enhance the operation of the
engine is the regulation of the maximum and minimum level
of the carburetor:
STANDARD ADJUSTMENT:
- OPEN INDICATED SCREW BY A QUARTER OF
REVOLUTION (3)
4.4 SCHEDULES AND GENERAL RECOMMENDATIONS
This paragraph lists a few recommendations that have been defined as a result of the
tests carried out by our mechanics and on the basis of the feedback provided by
customers. We kindly ask you to report anomalies or maintenance procedures that
are not described in this manual using the space provided in chapter 7.0. You can
also use this space for feedback or queries, to which we will be glad to answer.
Some components of SKY100 are subject to wear. Therefore, to avoid damaging the
engine or affecting its operation, we recommend you perform the operations
described below at the specified intervals:
Before flying, always check the safety devices of the muffler, silencer and filter box
(verify that the steel cables are in place and correctly connected).
Replace the sparking plug after approximately 80 hours of flight.
Inspect the silent blocks that support the radiator every 50 hours and replace them
after approximately 100 hours of flight.
The same applies to the silent blocks of the crosspiece and muffler, which have to be
replaced after 100 hours of flight.
Inspect the blocks of the clutch after approximately 50 hours of EFFECTIVE flight. For
information on how to disassemble them, see the section on the disassembly of
secondary components in Chapter 3.0.
• the depurtures increase the wearing out of the blocks of the clutch:an exagerated number of
departures decrease the effective hours of flight.in this case we recommend (especially to the
beginner, who are making exercises of departures) to check constantly the wear of the
different component of the clutch.
Replace the membranes of the carburetor after approximately 100 hours of flight.
Inspect the laminar bundle under the radiator every 50 hours of flight. Carefully
inspect the conditions of the blades because they could damage or break the engine
if damaged. Inspect the bank bearings approximately every 150 hours.
Regularly inspect the teeth of the flywheel.
CHECK THE LEVEL OF COOLANT INSIDE THE RADIATOR EVERY 10 HOURS OF
FLIGHT USING THE CAP SITUATED ON THE TOP OF THE RADIATOR, NOT THE
ONE IN THE DISCHARGE CONTAINER.
✓Our technicians recommend the use of Arexons Glitech 4100 Coolant
