SECTION 1
ENTRAPMENT1.10
Make sure all personnel are out of compressor before A.
closing and latching enclosure doors.
If the compressor is large enough to hold a man and B.
if it is necessary to enter it to perform service
adjustments, inform other personnel before doing so,
or else secure the access door in the open position to
avoid the possibility of others closing and possibly
latching the door with personnel inside.
JUMP STARTING1.11
Observe all safety precautions mentioned elsewhere A.
in this manual.
Batteries may contain hydrogen gas which is B.
ammable and explosive. Keep ames, sparks and
other sources of ignition away.
Batteries contain acid which is corrosive and C.
poisonous. DO NOT allow battery acid to contact
eyes, skin, fabrics or painted surfaces as serious
personal injury or property damage could result.
Flush any contacted areas thoroughly with water
immediately. Always wear an acid-resistant apron and
face shield when attempting to jump start the
compressor.
Remove all vent caps (if so equipped) from the D.
battery or batteries in the compressor. DO NOT
permit dirt or foreign matter to enter the open cells.
Check uid level. If low, bring uid to proper level E.
before attempting to jump start (not applicable to
maintenance-free batteries).
DO NOTF. attempt to jump start if uid is frozen or
slushy. Bring batteries up to at least 60 F (16 C)
before attempting to jump start or it may explode.
Cover open cells of all compressor batteries with clean G.
dampened cloths before attempting to jump start.
Attempt to jump start only with a vehicle having a H.
negative ground electrical system with the same
voltage, and is also equipped with a battery or
batteries of comparable size or larger than supplied in
the compressor. DO NOT attempt to jump start using
motor generator sets, welders or other sources of DC
power as serious damage may result.
Bring the starting vehicle alongside the compressor, I.
but DO NOT permit metal to metal contact between
the compressor and the starting vehicle.
Set the parking brakes of both the compressor (if J.
provided) and the starting vehicle or otherwise block
both sides of all wheels.
Place the starting vehicle in neutral or park, turn off all K.
non-essential accessory electrical loads and start its
engine.
Use only jumper cables that are clean, in good L.
condition and are heavy enough to handle the starting
current.
Avoid accidental contact between jumper cable M.
terminal clips or clamps and any metallic portion of
either the compressor or the starting vehicle to
minimize the possibility of uncontrolled arcing which
might serve as a source of ignition.
Positive battery terminals are usually identied by a N.
plus (+) sign on the terminal and the letters POS
adjacent to the terminal. Negative battery terminals
are usually identied by the letters NEG adjacent to
the terminal or a negative (-) sign.
Connect one end of a jumper cable to the positive O.
(POS) (+) battery terminal in the starting vehicle.
When jump starting 24V compressors and if the
starting vehicle is provided with two (2) 12V batteries
connected in series, connect the jumper cable to the
positive (POS) (+) terminal of the ungrounded battery.
Connect the other end of the same jumper cable to P.
the positive (POS) (+) terminal of the starter motor
battery in the compressor, or when jump starting 24V
compressor, to the positive (POS) (+) terminal of the
ungrounded battery in the compressor.
Connect one end of the other jumper cable to the Q.
grounded negative (NEG) (-) terminal of the battery in
the starting vehicle. When jump starting 24V
compressors and if the starting vehicle is provided
with two (2) 12V batteries connected in series,
connect the jumper cable to the negative (NEG) (-)
terminal of the grounded battery.
Check your connections. R. DO NOT attempt to start a
24V compressor with one 12V battery in the starting
vehicle. DO NOT apply 24V to one 12V battery in the
compressor.
Connect the other end of this same jumper cable to a S.
clean portion of the compressor engine block away
from fuel lines, the crank case breather opening and
the battery.
Start the compressor in accordance with normal T.
procedure. Avoid prolonged cranking.
Allow the compressor to warm up. When the U.
compressor is warm and operating smoothly at
normal idle RPM, disconnect the jumper cable from
the engine block in the compressor, then disconnect
the other end of this same cable from the grounded
negative (NEG) (-) terminal of the battery in the
starting vehicle. Then disconnect the other jumper
cable from the positive (POS) (+) terminal of the
battery in the compressor, or if provided with two (2)
12V batteries connected in series, from the
ungrounded battery in the compressor, and nally,
disconnect the other end of this same jumper cable
from the positive (POS) (+) terminal of the battery in
the starting vehicle or from the positive (POS) (+)
terminal of the ungrounded battery in the starting
vehicle, if it is provided with two (2) 12V batteries
connected in series.
