Filtration System - GEISMAR STUMEC MTZ 350S Manual

5.1.11 Filtration system

A dirty filtration system may lead to the
following problems occurring :
- High fuel consumption
- Problems in starting the engine
- A drop in engine power
- Premature engine wear
• At the end of every day's work :
➊ Unscrew the locking screw on the filter-
cover Ref.① (multi-purpose spanner).
➋ Remove the filter cover Ref.②.
➌ Clean inside and around the filter box, as
well as the inside surface of the filter
cover. Carry out this operation using
compressed air, taking care not to aim the
air directly at the main filter body.
• The two filter elements must be replaced if
they are clogged or damaged.
To avoid any dirt particles entering the
admission side of the engine, this operation
MUST be carried out in a clean area such as a
depot or a maintenance shop.
➊ Unscrew the four screws Ref.③ (multi-
purpose spanner).
➋ Take out the filter box Ref.④.
➌ Remove the main filter Ref.⑤ from the
filter box.
➍ Put the choke lever in position
➎ Remove the extra filter Ref.⑥ from the
base of filter Ref.⑦. Make sure no foreign
bodies enter the engine through the inlet
orifice.

➏ Clean the filter chamber.
➐ Re-assemble all the filter system elements in
reverse order to the dismantling procedure.
Given the exceptional conditions under which a
rail-cutting machine operates (great amounts of
dust created and a high dynamic load), the quality
of the filter elements used is of paramount
importance.
The air filters we recommend have been specially
designed for use on abrasive disk cutters and, as
such, meet special requirements concerning their
production and quality of manufacture as well as
the materials used :
- Extremely regular pore-size, fold forming and
very solid filter paper.
- High precision filter cartridges, with high-
pressure resistance capacity.

The filtration capacity and permeability to air of
all the filter elements on this rail-cutting machine
are perfectly matched.
For this reason, ONLY use recommended air
filters (references provided in § 5.2.2). The high
quality of these parts and carrying out the
recommended servicing and
operations will guarantee trouble-free use and a
long service life for your engine.
IMPORTANT: Should other makes of filter be
fitted, even if they appear to be the right size,
optimal protection of the engine unit against
incursion by impurities cannot be guaranteed. In
the event of excessive wear on engine parts or
deterioration of the engine unit resulting from the
use of non-approved filters, no requests for repair
under the terms of the guarantee may be
accepted.
