gcode to left nozzle/z axis

Hi,
I am editing the end section of the gcode so it stops everything when the machine stops printing, what is the gcode for lifting the nozzle for few mm from its relative place?
my current code is:
G1 E-2 F1800; retract 2mm
M104 S0 ; turn off temperature
M140 S0
M84 ; disable motors

is it enough for disabling all unnecessary operations (turn of the printer)?

Something like this sould do it:

G91 ; Set relative positioning
G1 Z1 F1000 ; Raise Z 1 mm
G90 Set absolute positioning
G1 X1 F1000 ; Move X carrige out of the way

Be sure to to test it..

Thanks, I took the first part it works well
