Komatsu GALEO HM350-2 Operation & Maintenance Manual page 128

OPERATION
DOES BODY POSITIONER OPERATE NORMALLY?
1. Turn the starting switch key to the START position and start the
engine.
2. Operate the dump control lever to the RAISE position, then
release it.
Check that the dump body stops before the end of the stroke.
REMARK
If the dump body reaches the end of the stroke, the contact of the
body will cause an impact. The body positioner is functioning, so
the dump body stops without any impact.
ARE THE CAB MOUNTING BOLTS AND PINS ARE FREE FROM LOOSENESS AND BREAKAGE?
Check that there are no loose cab mounting bolts (1) (left, right: 4
each). Tighten any loose bolts.
Tightening torque: 245 to 309 Nm{25 to 31.5 kgm, 180 to 227 lbft}
Check that there are no loose or broken cab mount pins (2) (left,
right: 1 each).
