(2) Maintenance and care
z
Always carry out maintenance work when the engine is switched off. If the
engine has to be maintained while it is running, e.g. changing the elements of
change-over filters, remember that there is a risk of scalding. Do not get too
close to rotating parts.
z
Change the oil when the engine is warm from operation.
CAUTION:
There is a rise of burns and scalding. Do not touch oil drain plug or oil filters
with bare hands.
z
Take into account the amount of oil in the sump. Use a vessel of sufficient
size to ensure that the oil will not overflow.
z
If change or refill the cooling water, disassemble the drain plug when the
engine has cooled down. Heated cooling water has the risk of scalding and
safety accidents.
z
Neither tighten up nor open pipes and hoses (lube oil circuit, coolant circuit
and any additional hydraulic oil circuit) during the operation. The fluids which
flow out can cause injury.
z
Fuel is inflammable. Do not smoke or use naked lights in its vicinity. The tank
must be filled only when the engine is switched off.
z
Keep service products (anti-freeze) only in containers which can not be
confused with drinks containers.
z
Comply with the manufacturer's instructions when handling batteries.
CAUTION:
Accumulator acid is toxic and caustic. Battery gases are explosive.
Therefore it should be done by an expert of the handling professionally.
(3) When carrying out checking, setting and repair work
z
Checking, setting and repair work must be carried out by authorized
personnel only.
z
Use only tools which are in satisfactory condition. Slip caused by the worn
open-end wrench could lead to injury.
