4.5 Motor hours counter / speed counter –
Motor Monitor PT 14 (Fig.11e)
Fig.11e
The engine monitor is an independent LCD counter for motor-
hours, a speed indicator and a measuring gauge for
maintenance. Energy is supplied from a lithium battery The
conductor around the sparking plug ensures both functions; the
signal of the counter for the revolutions, as well as an indicator
that the engine is running. For maintenance, this counter is
used in such a manner that the maintenance interval is set and
at the moment of expiration the counter reports the
requirement for the maintenance of the engine. Before setting
the counter each time, make sure that the engine is
disconnected. If it is necessary to unwind the black conductor
from the cable of the spark plug, for re-winding it is necessary
to perform only 3 ÷ 4 turns (otherwise the counter will not
show the correct values of the revolutions within the whole
range of the revolutions of the engine).

spark plug
Press and hold button S1 for 4 seconds. LCD displays 01 (the
spark plug is activated twice per revolution), 02 (once per
revolution), 03 (each further revolution), 04 (displays only
hours not revolutions). As soon as you find the required
diagram, release button S1. The LCD will flash 8-10s and
