7 General Maintenance
To Remove Left Rear Cover
196 7000/7010 Series TQ GC/MS Operating Manual
To Remove Left Rear Cover
The rear cover should be removed to open the rear analyzer side plate. This is
necessary when replacing the electron multiplier horn. If you need to access the
rear analyzer chamber, follow these procedures to remove the rear cover. (See
Figure 64 on page 197.)
Materials needed
• Screwdriver, Torx T-10 and T-20
Procedure
1 Loosen the top screw of the rear cover. It is captive so you will not be able to
remove it entirely. (See Figure 64 on page 197.)
2 Lift the bottom flap of the cover out of the groove in the back of the MS to
free the cover.
Do not remove any other covers. Dangerous voltages are present under the
other covers.
