The GTA Viewing/Fume Extraction Accessory (Optional)
Figure 21. The exhaust hose fits all the way into the accessory until it is level
with the white block at the bottom. Note the directional arrows.
To remove the exhaust hose from the adapter plate, simply unscrew it.
NOTE
Changing Location
To adjust the position of the accessory, tilt the base forwards and lift
it up slightly to enable the accessory to move freely. Move the
accessory to the desired position and then press it down to lock into
place.
Cleaning the Mirror
To clean the mirror, wipe the surface with a soft lint-free cloth. Take
care not to put finger marks on the mirror.
If the mirror is particularly dirty, water and detergent can be used
before wiping the surface with a soft lint-free cloth.
Cleaning the Accessory
The exposed parts of the GTA viewing/fume extraction accessory are
made of corrosion resistant materials. The exposed surfaces of the
exhaust inlet should be wiped down with a damp cloth if they
become dirty. If the exhaust hose becomes dirty, it may be removed
and cleaned with water. Refer to Page 51 for instructions on
removing the exhaust hose.
