To Drain Tank - Craftsman 16781 - Professional 80 Gal. Vertical Air Compressor Owner's Manual

TO DRAIN TANK
_Risk of Unsafe
Operation. Risk
from noise. Air tanks contain high
pressure air. Keep face and other
body parts away from outlet of
drain. Use ANSi Z87.1 eye protection
(CAN/CSA Z94.3) when draining as
debris can be kicked up into face.
Use ear protection (ANSi $12,6
(S3.19) hearing protection) as air flow
noise is loud when draining.
NOTE: Operation of the air compres-
sor will cause condensation to build up
in the air tank. Always drain tank on a
washable surface or in a suitable con-
tainer to prevent damaging or staining
surfaces.
1. Set the On/Auto/Off lever to "Off".
2. Close the globe valve.
3. Remove the air tool or accessory.
4. Open the globe valve and allow
the air to slowly bleed from the air
tank until tank pressure is approxi-
mately 20 PSI.
5. Close the globe valve.
6. Drain water from air tank by open-
ing drain valve on bottom of tank.
_Risk of Bursting.
Water will condense
in the air tank. if not drained, water
will corrode and weaken the air tank
causing a risk of air tank rupture.
_Risk of Property
Damage. Drain water
from air tank may contain oil and rust
which can cause stains.
7. After the water has been drained,
close the drain valve. The air com-
pressor can now be stored.
NOTE: If drain valve is plugged,
release all air pressure. The valve can
then be removed, cleaned, then rein-
stalled.
OIL
_Use air compressor
oil only. Multi-weight
automotive engine oils like 10W30
should not be use in air compressors.
They leave carbon deposits on
critical components, thus reducing
performance and compressor life.
NOTE: Use 30W compressor oil or a
heavy duty SAE 30W, non-detergent,
SF grade or better oil DO NOT use
multi-weight automotive engine oils,
they will reduce compressor life. Under
extreme winter condition use SAE-10
weight oil.
NOTE: Crankcase oil capacity is
approximately 48 fluid ounces (1.4 L).
Checking
1. The oil level should be to the
middle of the sight glass (C).
2. If needed remove oil fill plug (A)
and slowly add oil until it reaches
the middle of the sight glass.
Changing
1. Remove the oil fill plug (A).
2. Remove the oil drain plug (B) and
drain oil into a suitable container.
3. Replace the oil drain plug (B) and
tighten securely.
4. Slowly add compressor oil until
the oil level is in the middle of the
sightglass (C). NOTE: When filling
the crankcase, the oil flows very
slowly into the pump. If the oil is
added too quickly, it will overflow
and appear to be full.
_Risk of Unsafe
Operation. Overfilling
with oil will cause premature
compressor failure. Do not overfill.
5. Replace oil fill plug (A) and tighten
securely.
