CAUTION NOTES
a. Before putting the pump back into operation
after a breakdown, inspect it and check care-
fully for any other signs of damage.
b. Use only tools that are in perfect working or-
der and specially designed for the job; use of
inappropriate or ineffective tools may cause
serious damage.
c. Perform repairs in clean and, where possible,
dust-free areas. Protect all the clearances of
connection points with suitable plastic caps
and cover the machined surface areas of all
parts stripped down until they are put back on
the pump again.
d. Always check the lubricant and that it is prop-
erly distributed through the pump; inadequate
lubrication may damage the pump seriously.
MAINTENANCE ACTIONS
NOTE
The frequency with which repairs are performed de-
pends on the process and presence of substances
that shorten pump life (dust, abrasives, solvents,
water, chemically aggressive substances).
The pump must be cleaned at regular intervals of
time.
CAUTION
Do not clean with Alcohol the plastic or rubber
components of the pump.
Use only the strictly necessary amount of lubricant;
an excess of lubricating oil, like when there is
none, may sometimes compromise proper opera-
tion of the pump.
Only the recommended lubricants, or lubricating
oils with similar characteristics and known and ex-
perimented quality, should be used.
Oil changes must be made with the oil at a suffi-
ciently high temperature, after leaving the pump to
cool for a few minutes following operation.
The drain and filler plugs must not be left open any
longer than is strictly necessary.
When performing maintenance, look out for all sig-
nals that may precede a breakdown, in particular:
•
traces of corrosion;
•
oil
leaks;
•
slack joints or couplings.
Maintenance technicians must:
•
be aware of all applicable national directives
concerning accident prevention during work
on motor-driven pumps and should know how
to apply them;
•
have read and understood all the sections on
“Safety Rules";
•
be familiar with the essential design features
and operation of the pump;
•
know how to use and consult the pump docu-
mentation;
•
be concerned about proper operation of the
pump;
•
make a note of any irregularities in operation
of the pump and take the necessary action,
where appropriate.
Use original spare parts wherever possible and
repair a broken part as best as possible on site or
send it back to the manufacturer for repairs.
For all problems arising, or to order spare parts,
refer to our service department.

LUBRICANTS
It will be readily understood how important ade-
quate lubrication is to high technology pumps like
the Varian vacuum pumps. Correct use of appro-
priate lubricants makes a significant contribution to
achieving best performance and warding off de-
fects.
When handling lubricants, the following sanitary
protection measures should be observed at all
times:
•
Avoid prolonged, excessive or repeated con-
tact of the skin with products for lubrication,
and also avoid directly inhaling the fumes or
vapors of such products.
•
Protect the skin by wearing appropriate
clothes and equipment (e.g. special suits,
glasses or, where permitted by the safety
regulations, gloves) or by applying a special
protective product.
•
Clean the skin carefully after contact with the
lubricants by washing freely with water and
soap.
•
Apply a skin cream after washing.
