lows,

tyre). Each side must be extended or retracted half the desired alte-
ration.
2. Attach the sprayer to tractor and engage tractor parking brake.

wheel, support and secure sprayer body.

5. Loosen the pointed screw (B) on the brake operating arm.
6. Extend or retract the axle. A sack barrow and a rod will facilitate
the operation.
7. Tighten the clamp bolts (A) to a torque of 250 Nm.
8. Tighten the pointed screw (B) again.
9. Repeat the procedure on RH wheel.
10. Check if the distance from centre tyre to centre of rear frame is
equal at RH and LH.
11. Retighten bolts and wheel bolts to specified torque after 8 hours
of work.
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.
