z
Lower the speed of the engine, and examine the reason if engine oil pressure gauge is not in
the normal position in more than 10 seconds. After that, start again, otherwise there may be
some problem.

When the engine oil pressure does not reach the designated value, the high running speed of
the engine will induce a high temperature and the turbo charger may be broken.
z
Use the working equipment control levers to let the preheated hydraulic oil circle in
hydraulic tank and pipes, so that way the hydraulic parts can warm quickly.
z
Keep the engine at an idle speed for several minutes after starting. Increase the speed to
1000~1200r/min gradually, and then enter the partial load running status. Pay attention to the
value of the gauge.

If the engine has to run at idle status, the machine should be loaded from time to time or the
engine should run at the middle speed.
