increases this risk of explosion.<br />

for your engine.<br />
• See page 114 for more information.<br />

lines clear? If they are not being used, are they stored<br />
properly?<br />
• Is the trailer spare wheel secure and inflated?<br />
• Is the landing gear up and the handle secured?<br />
12. Check the fifth wheel. Is the kingpin locked?<br />
