Checks after inspection and maintenance:
Neglecting to perform these checks after inspection and mainte-
nance may cause unexpected problems resulting in serious
injury or property damage. Always proceed as follows:

Checks after operation (with engine off)

Were any inspection and maintenance points forgotten?

Were all inspection and maintenance items carried out
correctly?

Were any tools or parts dropped into the machine? It is
very dangerous if parts are dropped inside the machine
and become caught in the lever linkage.

Is there any leakage of water or oil? Have all the bolts
been tightened?

Checks with the engine running:
If a maintenance task must be carried out with the engine
running, perform the task with at least two workers and pro-
ceed as follows:

Park the machine on solid, level ground. Lower the work
equipment to the ground.

One worker must always sit in the operator's seat and be
ready to stop the engine at any time. The workers must
always maintain contact with each other.

Engage the work equipment lock lever.

Do not touch the control levers.

If any control lever must be operated, give a signal to the
other workers to warn them to move to a safe place.

Increase the engine speed to check for fuel and oil leak-
age.
