11.2 Air Tank Maintenance
Ensure that the accessory air tank is purged dur-
ing pre-starting inspection. A good practice is to
purge this tank at the end of every working day by
the remote air tank drain valve located in the
steering compartment (Fig. 28).
Moreover, purge all tanks by their bottom drain
valves at specified intervals.
This tank is installed above L.H. wheel of drive
axle, and is provided with a bottom drain valve. It
is recommended to purge the wet air tank by its
bottom drain valve every 12,500 miles
(20 000 km), or once a year, whichever comes
first.
A remote valve located in engine compartment
and accessible through engine R.H. side door is
used to drain the air dryer. On XL-40 & XL-45E
converted coach shell vehicles, the valve is posi-
tioned over battery assembly, close to door hinge
(Fig. 26). On XL-45, the valve is positioned under
back up alarm, close to L.H. side of door opening
(Fig. 27).
