COMPRESSOR MAINTENANCE
BEFORE EACH USE...
Check the TX200 Compressor oil level before each recovery procedure. The Oil Level Sight Glass is visible
through a cut-out on the side of the unit. The level should be maintained within the lower half of the sight glass.
Too much oil will cause the Compressor to be noisy; too little will cause it to overheat and may lead to piston
or bearing failure.
ADD COMPRESSOR OIL...
Run the TX200 with the Inlet Hose Ball Valve closed until the Compressor On Light goes Off. Press and hold
the Deep Vacuum Switch for approximately 30 seconds to draw a deeper vacuum. Leave the TX200 power on.
Pour 3GS Compressor Oil into the measuring cup. Insert the end of the Inlet Hose into the Oil and slightly open
the Ball Valve. Oil will be drawn into the TX200 due to the vacuum in the hose. Draw approximately 30 ml of
Oil into the TX200 and close the valve. Use the TX200 for a recovery job and again check the oil level.
CHANGE COMPRESSOR OIL...
The oil in the Compressor should be changed every 90 days (or after approximately every 100 jobs or 50 hours
of use). Change Compressor Oil as follows:
1. Disconnect power and remove cover.
2. Remove Caps from Vent Port (Upper) and Drain Port (Lower) on Compressor.
3. Remove Valve Cores from both ports and tip TX200 so Drain Port is at lowest possible level
(approximately 45
0 ).
4. Prop unit and allow Oil to drain for approximately 15 minutes.
5. Tip TX200 in opposite direction so the Drain and Vent Ports are at the highest possible level.
6. Use a syringe or oil injector at the Drain Port to re-fill the Compressor with 175 ml of Compressor Oil. Do
not exceed a total of 225 ml.
7. Replace the Valve Cores and Caps on the two Compressor Ports. Replace TX200 Cover.
8. Let the TX200 sit in the normal (level) position for 30 minutes to allow the Oil to settle.
9. Follow the above procedure "TO ADD OIL" until the Oil level is visible within the lower half of the Oil
Level Sight Glass.
