Before start up you ensure (it's a must) that:

- Cowl flaps are fully opened
- Fuel selectors: Right engines left tank and Left engine right tank
- Fuel and oil quantity is checked and cross-checked
Push the mixture leavers all the way forward, to the "rich" setting.
- These levers are easily identified as they are almost always a bright red colour.
Push the propeller leavers all the way forward, to the "high RPM" setting
- This leaver is usually light blue, however in this aircraft, it is black.
Pull the throttle leavers towards you - completely shut off
- This leaver is nearly always black.
Set the auxiliary fuel pump to "HI"
Push the throttle forward to obtain 60 lbs/hr fuel flow and then pull lever back to idle.
Switch the auxiliary fuel pump off
Check and re-check that the propeller area is clear
Turn the ignition switch to the start position
Slowly advance the throttle forward
Release the ignition switch when the engine starts
Set the throttle to 800-1000 RPM
Check and cross-check oil pressure
Repeat steps 4 to 12 to start the other engine

Always keep your eyes on oil pressure and fuel levels throughout the start up process
