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 Vacuum Pump 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 1 ounce 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 6 ounces of
3GS Compressor Oil. Do not exceed a total of 8 ounces.
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.
