Polini Motori THOR 202 Instructions Pour L'utilisation Et L'entretien page 17

All the parts in movement, including the springs, must be well lubrica-
ted. Now go on by charging the return spring: take the head of the rope
leaving 10-20 cm coming out the hole with "u" shape on the wheel side.
Turn the wheel three times in counter clock-wise sense till it stops in
front of the exit hole on the aluminium case. Keeping the plastic wheel
stopped, pass the rope through the case hole. Insert the handle and the
washer and tie a single knot as shown in photo 9.
!
ATTENTION: verify that the return spring does not reach the
end of the stroke. Pull the rope completely and turn the wheel again to
check that it can make at least one turn before stopping.
This test is very important because the spring hasn't been studied to
reach the end of the stroke and, if it happens, the spring will break.
Reassemble the starter in the engine and tight the 4 screws (M5) with
strength (see the tightening torque values table).
15- HOW TO CHECK THE COOLING SYSTEM LEVEL
Periodically check the cooling system: when the engine is cold the coo-
lant must cover the last radiator part (photo 10).
COOLING LIQUID LEVEL
If necessary add some liquid, using the one specific for aluminium radiator.

!
CAUTION: never open the cap when the engine is hot, you could burn.
15.1 HOW TO EMPTY THE COOLING SYSTEM
If necessary empty the cooling system by unscrewing the proper screw
(see photo 11) and collect the leaking liquid. Remove the cap to make
this operation easier.

!
CAUTION: Do not empty it when the engine is hot, you could
burn.
15.2 HOW TO FILL IN THE COOLING SYSTEM
Fill in the cooling system using coolant specific for aluminium radiator
till covering the last part of the radiator (photo 10). To make this opera-
tion easier and eliminate possible air bubbles inside the cooling system,
press several times the pipe placed at the base of the radiator, to check
the proper liquid level.
We recommend starting the engine for some minutes, then switch it off
and check the level again.
!
CAUTION: check the coolant before every use
16- ADVANCE TIMING SETTING
This adjustment is necessary only if the ignition has been disassembled
and it must be done by qualified people only owning the necessary
tools. Screw one m.5x30 screw in the hole with thread passing through
the flywheel and lock it. Assemble the flywheel and insert the screw in
the case: the flywheel will be fixed (Photo 12).
