
Remember that ethylene glycol liquids and "Tosol" are
toxic if swallowed.

Use fire extinguishers to extinguish a burning fuel spill,
throw sand onto the fire, cover it with asbestos blanket, felt
or tarpaulin. Don’t pour water onto the flame.

When performing electric welding operations directly on
the vehicle, open the master disconnect switch and
disconnect the wire from the «+» generator terminal in
order to prevent breakdown of the electronic control system
and the regulating relay. The welding machine ground cable
must be connected in close proximity to the welded seam.

Take measures to prevent contact of sparks and molten
metal drops formed during welding with wiring harnesses,
fuel pipes and other engine parts and units which are
vulnerable to heat damage.
ATTENTION! THE ELECTRONIC CONTROL SYSTEM OF OUR
ENGINES PREVENTS FROM EXCEEDING UPPER LIMITS OF
R.P.M. AND COOLANT TEMPERATURE AND LOWER LIMIT OF
OIL PRESSURE.
THE ENGINES ARE AUTOMATICALLY STOPPED IN
EMERGENCY CONDITIONS.
