ATTENTION! Depending on configuration of the machine the
track gauge can be altered in the range from 1500 mm to
2000 mm, or from 1800 mm to 2250 mm.
ATTENTION! When wheels has been mounted or re-tightened,
the plastic nut covers must be placed on the nuts afterwards.
ATTENTION! The wider the track width is, the better is the sta-
bility of the sprayer. HARDI recommends to work with widest
possible track width.
WARNING! Place the jack under the axle and lift the wheel to
remove load from the clamps before tightening the clamp
bolts to the specified torque.
The track gauge of the COMMANDER can be altered stepless as fol-
lows,

tyre). Each side must be extended or retracted half the desired alte-
ration.
