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.
