Welding instructions:
 Before beginning welding, proceed as follows:
 Turn the starting switch to the OFF position.
 Switch the battery main switch off once the green pilot
lamp on the relay box has gone out.
 Do not apply a continuous voltage of more than 200 V.
 Connect the earthing wire at a maximum distance of 1 m to
the weld area.
There must not be any gaskets or bearings between the weld
area and the earthing point.
Never weld lines or pipes containing fuel or oil.
Do not drop objects into the machine:
 When opening inspection windows or filler necks, be careful
not to drop screws, nuts, or tools into the machine.
If such objects are dropped into the machine, they will dam-
age the machine and cause malfunctions leading to machine
failure. If you drop anything inside the machine, always
remove it immediately.
 Do not carry unnecessary objects in your pockets. Carry only
the things that are necessary for the inspection.
Dusty worksites:
Proceed as follows when working in dusty environments:
 Frequently check the air cleaner caution lamp for clogging of
the air cleaner.
Clean the air cleaner more frequently.
 Periodically clean the cooler block to prevent clogging.
 Periodically clean and replace the fuel filter.
 Clean electrical components, especially the starter motor and
alternator, to prevent accumulation of dust.
 When inspecting or changing the oil, move the machine to a
place that is free of dust to prevent oil contamination.
