brake operating arm.
6. Extend or retract the axle. A sack barrow and a rod will facilitate the
operation.
7. Lower down the left wheel.Tighten the clamp bolts (A) to a torque
of 250 Nmand lock the bolts with the counternuts.
8. Repeat the procedure on right wheel.
9. Check if the distance from centre tyre to centre of rear frame is equal at right and left side.
10. Retighten bolts and wheel bolts to specified torque after 8 hours of work.
