Park machine inside a building overnight, if possible.
Turn key on and watch display for glow plug cycle to end, indicating it is okay to start machine.
If your machine is equipped with a “Cold Start,” engage that manually on cold days to start the machine engine only, wait 5-10 minutes for the engine to warm up before, then disengage the Cold Start to turn on the machine hydraulics. To warm up machine hydraulics, pick a small motor (like hammer rotation) and spin for 5-10 minutes.
Some Machines have automatic warm-up cycles. If machine is in automatic warm-up cycle mode at startup, the display unit will prompt you.
NOTE: Each machine’s warm-up cycle is explained in the owner’s manual for that particular machine.
Use Glow plug pre-heater at temperatures below 50 degrees F.
Do not use Glow plug pre-heater more than 20 seconds.
With the ignition switch held in the pre-heat (counterclockwise) position, the glow plugs remain on even after light goes off.
Even if red light is on, this does not mean the glow plugs are getting 12 volts.
Do NOT crank engine more than 10 seconds at a time.
Check 30A fuse if engine will crank but not start.
Once warmed up you may have to bleed fuel system.
For machines that are equipped with a 12V fuel pump such as 6620, and 7822DT…
For machines not equipped with a 12V pump such as 54LT, 540UD…
Note: Never open injector lines to bleed fuel system. Will void engine warranty.
