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 safety glasses [ANSI Z87.1 (CAN/CSA Z94.3)]
when draining as debris can be kicked up into face. 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 On/Off switch is in the OFF position.
2. Place a suitable container under the drain valve to catch
discharge.
WARNING: 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.
CAUTION: Risk of property damage. Drain water from air tank may
contain oil and rust which can cause stains.
3. Grasp black lever on drain valve (J).
4. Slowly rotate lever to gradually bleed air from air tank.
5. Grasp black lever on other drain valve and rotate to approximately
the same position as the first.
6. When air tank pressure gauge reads 10 PSI (68.9 kPa), rotate
valve to the fully open position.
7. Close drain valves when finished.
Compressor Pump Oil (Fig. 1)
CHECKING OIL
WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head and
surrounding parts are very hot, do not touch (see the Hot Surfaces
identified in Fig. 2). Allow compressor to cool prior to servicing.
CAUTION: Risk of unsafe operation. Overfilling with oil will cause
premature compressor failure. Do not overfill.
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.
1. Ensure On/Off switch is in the OFF position.
2. Place unit on a flat level surface.
3. FOR K PUMP UNITS
• Remove dipstick (K) and wipe clean.
• Insert and remove dipstick without
threading dipstick into crankcase as
shown in figure.
• Check the oil level on dipstick.
If oil level is at or below "Add",
oil needs to be added. Add D
synthetic oil to the proper maximum
level as shown in figure.
FOR G PUMP UNITS
• Remove oil fill plug (K).
• Check the oil level. Oil should not
exceed top raised line on side of
crackcase. (Oil will be even with
bottom of threads in crankcase fill
port), if needed add D
synthetic oil to the proper level.
