WARNING
Never point a spray gun at yourself or any
other person or animal. Accidental discharge
may result in serious injury.
Reduce the risk of dangerous
environment
WARNING
Extreme caution should be taken when
spraying flammable liquids as the spark from
a motor or pressure switch may cause a fire
or explosion. Ample ventilation must be
provided.
WARNING
Spray in a well ventilated area to keep fumes
from collecting and causing serious injury and
fire hazards.

Perform these maintenance operations

1. Do regular maintenance; keep all nuts, bolts,
and screws tight, to be sure equipment is in
safe working condition.
2. Inspect tank yearly for rust, pin holes or any
other imperfections that could cause it to
become unsafe.
WARNING
NEVER attempt to repair or modify a tank!
Welding, drilling or any other modification will
weaken the tank resulting in damage from
rupture or explosion. Always replace worn,
cracked or damaged tanks.
3. Clean electrical equipment with an approved
cleaning agent, such as a dry, non-flam-
mable cleaning solvent.
Daily
Check oil level at sight glass.
Drain moisture from tank.
Verify the pressure switch unloader is
working by listening for a brief hissing sound
when the compressor shuts off.
Visually check the compressor for loose parts,
excessive noise or vibration.

Spraying precautions

1. Do Not spray in the vicinity of open flames
or other places where a spark can cause
ignition. Do Not smoke when spraying
paint, insecticides, or other flammable
substances.
Be informed about the materials you use
1. When spraying with solvents or toxic chemi-
cals, follow the instructions provided by the
chemical manufacturer. Consult a safety
expert if unsure about the use of masks or
respirators.
2. If the material you intend to spray contains
trichloreoethane and methylene chloride, do
not use accessories that contain aluminum or
galvanized materials, as these chemicals can
react with galvanized components causing
corrosion and weakening equipment. Use
stainless steel accessories.
4. Drain tanks of moisture after each day's use.
If unit will not be used for awhile, it is best to
leave the drain cock open until such time as it
is to be used. This will allow moisture to
completely drain out and help prevent
corrosion of inside of tank.
5. Always disconnect from power source before
working on or near a motor, or its connected
load. If power disconnect point is out-of-
sight, secure it in the "OFF" position and tag it
to prevent unexpected application of power.
Disconnect power and depressurize system
before servicing air compressor. Slightly open
drain cock after shutting off compressor.
Monthly
(Make sure the main power is off.) Check the belts
for tension. Belts should not move up and down
when the compressor runs and when stopped,
should not have more than ½ in of play when
depressed. Be careful not to over tighten belts
during adjustment.
Remove and check air filter, replace if necessary.
Change oil every 3 months or 300 hours. A
compressor grade non-detergent oil should be
used. (40 wt for 3848 and 30wt for Models
93274 and 90836).
