Procedure
Check safety valve
Inspect air filter
Drain air tank
Check for unusual noise/vibration
Check for air leaks 1
Clean compressor exterior
Remove tank from service
1 - To check for air leaks apply a solution of soapy water around joints.
While compressor is pumping to pressure and after pressure cuts
out, look for air bubbles to form.
2 - For more information, call 1-800-4-D
Checking Safety Valve
WARNING: Risk of bursting. If the safety valve does not work
properly, over­pressurization may occur, causing air tank rupture or
an explosion.
WARNING: Risk from flying objects. Always wear certified safety
equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side
shields when using the compressor.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. nOte: Ring may
be difficult to pull when air tank pressure is at 0 psi. If the valve is
stuck or does not operate smoothly, it must be replaced with the
same type of valve.

Draining Air Tank (Fig. 1)
WARNING: 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 eye protection [ANSI Z87.1 (CAN/CSA Z94.3)]
when draining as debris can be kicked up into face.
WARNING: Risk from noise. Use ear protection [ANSI S12.6
(S3.19)] as air flow noise is loud when draining.
nOte: All compressed air systems generate condensate that
accumulates in any drain point (e.g. tanks, filter, aftercoolers,
dryers). This condensate contains lubricating oil and/or substances
which may be regulated and must be disposed of in accordance with
local, state, and federal laws and regulations.
1. Ensure Auto/Off switch is in the OFF position.
2. Place a suitable container under the drain valve (H) to catch
discharge.
3. Grasp lever on drain valve.
4. Slowly rotate lever to gradually bleed air from air tank.
WARNING: Risk of bursting. Drain air tank daily. Water will
condense in air tank. If not drained, water will corrode and weaken
the air tank causing a risk of air tank rupture.
NOTICE: Risk of Property Damage. Drain water from air tank may
contain oil and rust, which can cause stains.
5. When air tank pressure gauge reads 10 psi, rotate valve to the
fully open position.
6. Close drain valve when finished.
