IMPORTANT: Do not use starting assist fluids. Use of
such fluids in the air intake system may be potentially
explosive or cause a “Runaway” engine condition and
could result in serious engine damage.
1.
Sit in operator’s seat, make sure mow switch (B) is
OFF, and traction pedal (K and L, Figure 4B) is in
Neutral.
2.
Turn system power switch (H) to RUN. Steering
controller will initialize, LDU (A) will display
Jacobsen start up screen, and all lights on LDU will
be on for two seconds.
After LDU initializes, green power light will be
flashing two times per second and parking brake light
will be on. Engine oil pressure light will be on for
diesel and gas power modules.
Gas Power Modules: Pull the choke control knob
out to close the choke plate when starting a cold

1 to 6 seconds during initialization, do not attempt to
start engine until glow plug light turns off.
3.
Turn system power switch (H) to START position.

position for more than 10 seconds. Once engine
starts, engine oil light (P) should go out, green power
light will be solid on and traction and mow systems
will be active.
NOTE: Engine speed is adjusted by the engine
controller and cannot be changed by the operator.
4.
