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

BEFORE STARTING THE ENGINE
On receipt of machine, 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
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 radiator. Be sure to add Alfloc 2000 to
radiator as per container instructions. This is
required for corrosion resistance.
3. Fill the fuel tank (always use clean fuel).
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

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 8.
CAUTION
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
either turned off or the plugs pulled. If the load is
left connected it may prevent the generator from
building up to full voltage.

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 "Hs" position. If the engine does not start after 20
seconds, return the switch to the "H" position for 10
seconds and then return to the "Hs" position 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 "R" position. If the engine is warm and has only been
stopped for a short period, restart by turning the start
switch directly on to the "Hs" position and releasing when
the engine starts.
