Ether fuel Systems

Ether fuel systems are used for diesel cold starting.
1 1 Do not use ether as a starting aid in conjunction with
other stating aids (i.e. glow plug, air intake heater etc.)
as an explosive condition may result in severe engine
damage or personal injury.
2 This type of fuel is extremely flammable, toxic and
poisonous. Avoid contact with eyes or skin and
breathing the fumes. If accidentally swallowed, do not
induce vomiting but call a physician immediately.
3 If fuel enters or fumes irritate the eyes, flush the latter
with large quantities of clean water and call for medical
aid.
4 Before operating ether cold starting aids, read the
instructions and the container label.
5 Never operate ether cold starting aids while the engine
is running as this can cause severe damage.
6 When maintenance, tests or repair has to be performed,
do so in a well-ventilated area only, away from heat,
open flame or sparks. Ascertain that the area is clearly
marked out with signs prohibiting fire, open flame and
smoking.
7 Wear eye protection when testing a system. Make sure
that openings of a spray container, valve, tube or
atomizer are pointed away from yourself and others
while testing.
8 Do not store ether containers in temperatures above
160 ºF (70ºC),
9 Do not incinerate, puncture or attempt to remove the
center core valve, side safety valve or any other part of
an ether container.

Pressure vessels

Maintenance/installation requirements:
1 The vessel can be used as pressure vessel or as
separator and is designed to hold compressed air for the
following application:
- pressure vessel for compressor,
- medium AIR/OIL,
and operates as detailed on the data plate of the vessel:
- the maximum working pressure ps in psi (bar),
2 The pressure vessel is only to be used for the
applications as specified above and in accordance with
the technical specifications. Safety reasons prohibit
any other applications.
3 National legislation requirements with respect to re-
inspection must be complied with.
4 No welding or heat treatment of any kind is permitted
to those vessel walls which are exposed to pressure.
5 The vessel is provided and may only be used with the
required safety equipment such as manometer,
overpressure control devices, safety valve, etc.
6 Draining of condensate shall be performed daily when
vessel is in use.
7. Installation, design and connections should not be
changed.
8. Bolts of cover and flanges may not be used for extra
fixation.

Safety valves

All adjustments or repairs are to be done by an authorized
representative of the valve supplier.
Following checks must be carried out:
1 A check of the opening of the lifting gear,1 or 2 times
a year. This can be done by lifting the ring or lever.
2 A check of the set pressure once a year according to the
local regulations, if required. This check may not be
done with the compressor supplying the air pressure
and must be carried out on a proper test bench.

Injury Prevention

1 Stationary housing guards are provided on all rotating
or reciprocating parts not otherwise protected and
which may be hazardous to personnel. Machinery shall
never be put into operation, when such guards have
been removed, operate only when guards are securely
reinstalled.
2 Do not open electrical cabinets, cubicles or other
equipment while voltage is supplied. If such cannot be
avoided, e.g. for measurements, tests or adjustments,
have the action carried out by a qualified electrician
only, with appropriate tools, and ascertain that the
required bodily protection against electrical hazards is
applied.
3 Noise, even at reasonable levels, can cause irritation
and disturbance which, over a long period of time, may
cause severe injuries to the nervous system of human
beings.
When the sound pressure level, at any point where
personnel normally has to attend, is:
- 10 -
below 70 dB(A): no action needs to be taken,
above 70 dB(A): noise-protective devices should be
provided for people continuously being present in the
room,
below 85 dB(A): no action needs to be taken for
occasional visitors staying a limited time only,
above 85 dB(A): room to be classified as a noise-
hazardous area and an obvious warning shall be
placed permanently at each entrance to alert people
entering the room, for even relatively short times,
about the need to wear ear protectors,
above 95 dB(A): the warning(s) at the entrance(s)
shall be completed with the recommendation that also
occasional visitors shall wear ear protectors,
above 105 dB(A): special ear protectors that are
adequate for this noise level and the spectral
composition of the noise shall be provided and a
special warning to that effect shall be placed at each
entrance.
4 Insulation or safety guards of parts the temperature of
which can be in excess of 80 ºC (175 ºF) and which
may be accidentally touched by personnel shall not be
removed before the parts have cooled to room
temperature.
5 When hot parts have to be handled, e.g. shrink fitting,
special heat-resistant gloves shall be used and, if
required, other body protection shall be applied.
6 If the working process produces fumes, dust or
vibration hazards, etc., take the necessary steps to
eliminate the risk of personnel injury.
7 Before lifting machines, all loose parts which could be
liable to fall down shall be removed or secured;
pivoting parts such as doors, etc. shall be safely
immobilized.
8 To lift heavy parts, a hoist of ample capacity, tested and
approved according to local safety regulations, shall be
used.
9 When lifting machinery, only hooks or shackles
meeting local safety regulations shall be applied. Never
shall cables, chains or ropes be applied directly on or
through lifting eyes. Never allow sharp bends in lifting
cables, chains or ropes.
10 Lifting hooks, eyes, shackles, etc. shall never be bent
and shall only have stress in line with their design load
axis. The capacity of a lifting device diminishes when
