Please consult your local Ingersoll---Rand branch or dealer when
these procedures become due.

COLD WEATHER OPERATION
A. Fuel Selection
In cold weather, the fuel might freeze resulting in difficult engine
starting; therefore, select a suitable fuel for such engine
operation. Use ASTM 975 No. 2---D fuel if you expect temperature
above ---7
˚
C (20
˚
F).
Use No. 1---D if you expect temperatures below ---7
˚
C (20
˚
F).
If No. 1---D is not available, a “winter” blend of No. 1---D and No.
2---D is available in some areas during the winter months.
Check with your fuel supplier to be sure you get the correct
blended fuel.
B. Coolant
Where the ambient temperature falls below freezing point, the
cooling system should be drained after engine operation, but to
eliminate the need for repeated draining, refilling and to provide
all year protection against corrosion, the use of anti---freeze
solution throughout the year is highly recommended.
All Ingersoll---Rand portable compressor engines are factory
filled with a 50/50 % ethylene glycol base antifreeze/water mix
which provides protection to ---33
˚
C (---27
˚
F).
Concentrations over about 65 % adversely affect freeze
protection, heat transfer rates, and silicate stability which may
cause wate pump leakage.
CAUTION
NEVER EXCEED A 60/40 % ANTIFREEZE/WATER MIX (WHICH
PROVIDES PROTECTION TO ABOUT ---50
˚
C (---58
˚
F).
NOTE
Methyl alcohol base antifreeze is not recommended because of
its effect on the non---metallic components of the cooling
system and because of its low boiling point.
NOTE
High silicate antifreeze is not recommended because of
causing serious silica gelation problems.
NOTE
Usage and mixing ratio etc. should be followed to the antifreeze
manufacture’s recommendations.
C. Engine Oil
At low ambient temperatures, engine oil viscocity can affect
engine starting. It is important to use the correct grade of oil as
recommended in
Figure 13---3 OPERATING TEMPERATURE
.
Try to position the compressor where it will not be affected by
cold winds when not running.
D. Battery
(1.) Always ensure that the batteries are kept fully charged in the
cold season. This takes a longer period of running than in
warm weather operation.
The electrolyte in a partly discharged battery will freeze easier
than when it is fully charged. Try to keep the batterys fully
charged and warm in cold weather operation.
(2.) Top up the battery with distilled water immediately before
starting the engine.
E. Cold Starting
When operating in cold ambient conditions, or when starting
from cold, observe the following procedures:
---
Turn the key switch to position
II
(GLOW) and hold for
between 5÷15 seconds. This action operates the glow
plugs.
---
If the engine does not start at the first attempt, allow the
battery to recove for at least 30 seconds then repeat step 1)
above.
---
In order protect the starter, do not engage for longer than 10
seconds during any attempt.
---
If during cranking, the starter motor reatedly engages and
disengages the battery power could be low. Either recharge
the battery or replace it with one that is fully charged.
NOTICE
Do not use starting “aids” in the air intake system. Such aids
can cause immediate engine damage.
