Every 100 Hrs

Every 150 Hrs

Every 200 Hrs

1.

 Check torque of all 

screws and nuts of the 
engine, exhaust, frame, 
and cylinder head; with 
a cold engine too avoid 
malformation. 

2. 

Check the sparkplug, 

the inner part should be

kit.

3. 

Check thickness of 

clutch del ferodo.

4.

 Piston rings.

5. 

Clean carbon residue 

from clutch and exhaust 
manifold, piston head 
cylinder manifold. 
Check needle-bearing 
set by vertically moving

6.

 Replace cylinder 

gasket and and cylinder 
head gasket. 

1. 

Replace reduction

replace those that are 
worn or not elastic.

IMPORTANT: 

IS ESSENTIAL TO TIGHT THE HEAD CYLINDER AFTER THE FIRST FLIGHT HOUR 

It is necessary to tight the head cylinder nuts after the first flight hour accorded with the table of pairs of tightens and 
using for it a dynamometric key.  
For the 

RM80

 the head cylinder pair of tightens is of 

0.9 KGM/9 NM

 and 

1.6 KGM/16 NM

 for the 

PA125

SPECIAL ATTENTION BEFORE THE FIRST USE: 

It is necessary to have a special care when you pump the gasoline before the first use to prevent some gasoline does 
not fall on the exhaust pipe. If there is some fuel on the exhaust you have to leave it dried before passing a rag.

 WE RECOMMEND TO ALWAYS FILTER THE FUEL WHEN YOU FILL THE DEPOSIT. 
 

TAKE OFF THE CARBURETTOR INNER FILTER.

REDUCTOR GEAR AND TRANSMISSION

The reductor gear leaning in oil bath is quite efficient 
and reliable, and has a very low noise production.
Its ratio is 3,65 / 1. Almost no maintenance and ad-
justments are necessary, except check
every 100 hours that oil level and state of the clutch 
are correct.
The transmission from the crankshaft to the reductor 
gear is connected by means of a dry centrifugal
clutch that allows the propeller to be not moving 
when idle. No maintenance is required.
The amount of oil to apply is: 

20 ml. 75W – 90.

IMPORTANT

This screw is used 
to change the oil 
but not to check 
the level.
