Engine Operation
On receipt of 400 AS-50, remove “Gold Seal” or “Carecard” label
from engine, add ownership details, and mail to nearest Perkins
Distributor. The Distributor will return a plastic Carecard which
must be retained and presented should warranty service be
required. Note that the Carecard is accepted world-wide.
Before attempting to start the engine, the following should
be carried out:
1. Ensure the crankcase oil level is at the “Full” mark on the
dipstick. Use only the grade oil recommended by the
engine manufacturer in accompanying Engine Manual.
N.B.: Many oil companies market a product which meets
the recommended MIL-L-46152 (SE CC) and the heavy
duty and turbocharged engine specification MIL-L-2104C
(SE CD). These oils are not recommended for use in this
welder, particularly in the initial 50 hours of operation.
2. Fill the fuel tank (always use clean fuel).
3. Fill the radiator. Be sure to add Alfoc 2000 or equivalent to
radiator as per container instructions. This is required for
corrosion resistance.
A water/glycol mixture is
recommended for use in cold temperature conditions.
4. In the case of a new engine or an engine which has been
standing idle for any length of time, it is important to bleed
the fuel system. Always use the manual primer on the lift
pump to circulate fuel in the system. Extensive use of the
electric starter for this purpose may lead to electrical
component damage. Refer to the engine instruction
manual for the correct procedure.
5. Fill the dry charged battery. See page 6.
Before Starting the Engine
To Start the Welder
Turn the start switch to the “H” position for 15-20 seconds, then
turn further in the clockwise direction to the “start” position. If the
engine does not start after 30 seconds, return the switch to the
“H” position for 10 seconds and then return to the “start” position.
Then engage the starter motor again for a maximum period of 30
seconds. If the engine still does not start, allow at least 10
minutes for the starter motor and other electrical components to
cool before repeating the starting procedure. As soon as the
engine starts, the start switch should be released and allowed to
return to the “on” position. If the engine is warm and has only
been stopped for a short period, restart by turning switch directly
on to the “start” position and releasing when the engine starts.
Note: The “H” position is midway between the “on” position
and the “start” position. A definite spring loaded location can
be felt at the “H” position.
If the oil pressure gauge does not show normal oil pressure
(200/420kPa) 10 seconds after starting, stop the engine and
consult the engine instruction manual.
The engine speed has been pre-set in the factory for optimum
welder performance and the fuel pump and governor then sealed.
This setting should not be altered, to do so will void the warranty.
For normal running, lubricating and maintenance instructions,
consult the engine instruction manual. For correct cooling air flow,
the welder should be operated with the doors closed.
TO STOP THE ENGINE
Turn the key switch to “off” position.
FOR OPTIONAL ENGINE WATCHER OPERATION:
When an engine watcher option is fitted to a 400AS-12V, two (2)
warning lights are mounted on the control panel. These are
located in the area of the key switch.
The light beside the key switch is the battery charge alternator
light. If this light glows after the engine has reached operating
speed there is a fault in the battery charge alternator and the
battery is not being charged.
The second light, mounted above the battery charge alternator
light, is the engine watcher operation light. This light glows to
indicate that the engine watcher is functioning correctly.
OPERATING INSTRUCTIONS
IMPORTANT NOTE ABOUT “RUNNING IN” YOUR DIESEL ENGINE
All diesel engines require some additional care for about the first 50 hours operation. While maximum load can be applied to a
new engine as soon as it is put into service and the coolant temperature has reached at least 60°C, care should be taken that
the engine is not run at very light loads (say less than 2.4 kVA, or a 10 amp radiator) for extended periods, as this can lead to
glazing of the cylinder bores. Do not operate at high speeds without a load, and do not overload the engine. Cylinder glazing
can lead to excessive oil consumption and smoky exhaust, while overloading during the first few hours can lead to excessive
wear and shorten the life of the engine.
FOR ENGINE
powered equipment
Operate internal combustion engine in open, well ventilated
areas or vent the exhaust fumes outdoors. Whenever
starting the engine, be sure any welding loads are removed
and any A.C. auxiliary loads are either turned off or the
plugs pulled. If the load is left connected it may prevent the
generator from building up to full voltage.
CAUTION
Failure to return the key switch to “on” position, or turning
to “start” position while engine is running will cause
electrical component damage.
