3700 Operator’s Manual and Parts List
I. The antifreeze compound used in air line 
antifreeze systems contains methanol and is 
toxic, harmful or fatal if swallowed. Avoid contact 
with the skin or eyes and avoid breathing the 
fumes. If swallowed, induce vomiting by 
administering a tablespoon of salt, in each glass 
of clean, warm water until vomit is clear, then 
administer two teaspoons of baking soda in a 
glass of clean water. Have patient lay down and 
cover eyes to exclude light. Call a physician 
immediately.
1.8 ELECTRICAL SHOCK
A. This compressor should be installed and 
maintained in full compliance with all applicable 
Federal, State and Local codes, standards and 
regulations, including those of the National 
Electrical Code, and also including those relative 
to equipment grounding conductors, and only by 
personnel that are trained, qualified and 
delegated to do so. 
B. Keep all parts of the body and any hand-held tools 
or other conductive objects away from exposed 
live parts of electrical system. Maintain dry 
footing, stand on insulating surfaces and DO NOT 
contact any other portion of the compressor when 
making adjustments or repairs to exposed live 
parts of the electrical system. Make all such 
adjustments or repairs with one hand only, so as 
to minimize the possibility of creating a current 
path through the heart.
C. Attempt repairs in clean, dry and well lighted and 
ventilated areas only.
D. DO NOT leave the compressor unattended with 
open electrical enclosures. If necessary to do so, 
then disconnect, lock out and tag all power at 
source so others will not inadvertently restore 
power.
E. Disconnect, lock out, and tag all power at source 
prior to attempting repairs or adjustments to 
rotating machinery and prior to handling any 
ungrounded conductors.
1.9 LIFTING
A. If the compressor is provided with a lifting bail, 
then lift by the bail provided. If no bail is provided, 
then lift by sling. Compressors to be air-lifted by 
helicopter must not be supported by the lifting bail 
but by slings instead. In any event, lift and/or 
handle only in full compliance with OSHA 
standards 29 CFR 1910 subpart N and/or any 
applicable Federal, State, and Local codes, 
standards and regulations.
B. Inspect points of attachment for cracked welds 
and for cracked, bent, corroded or otherwise 
degraded members and for loose bolts or nuts 
prior to lifting.
C. Make sure entire lifting, rigging and supporting 
structure has been inspected, is in good condition 
and has a rated capacity of at least the weight of 
the compressor. If you are unsure of the weight, 
then weigh compressor before lifting.
D. Make sure lifting hook has a functional safety 
latch or equivalent, and is fully engaged and 
latched on the bail or slings.
E. Use guide ropes or equivalent to prevent twisting 
or swinging of the compressor once it has been 
lifted clear of the ground.
F. DO NOT attempt to lift in high winds.
G. Keep all personnel out from under and away from 
the compressor whenever it is suspended.
H. Lift compressor no higher than necessary.
I. Keep lift operator in constant attendance 
whenever compressor is suspended.
J. Set compressor down only on a level surface 
capable of safely supporting at least its weight 
and its loading unit.
A DANGER
All field equipment must be tested for 
electrostatic fields prior to servicing or 
making contact with the machine using 
the following or equivalent test 
equipment:
• 90-600 VAC: Volt detector such as Fluke 
Model 1AC-A
• 600-7000 VAC: Voltage detector such as 
Fluke Networks Model C9970
It is the responsibility of each 
organization to provide/arrange training 
for all their associates expected to test for 
electrostatic fields.
