REPLACING THE FEED PUMP FILTER
• Do not smoke or permit open flames
while handling fuel or working on the
fuel system.
• Stop the engine in a well-ventilated
place and allow it to cool down before
performing maintenance.
• Clean up spilled fuel immediately.
• Before performing maintenance on top
of the work bench, clean the footing and
observe the following precautions to
prevent falling.
· Do not spill oil or grease.
· Do not leave tools scattered around.
· Watch your step when walking.
• Never jump down from the machine or
the work bench. When getting on or off
the machine or work bench, use the
steps, handrails or work bench to
support your body. Your weight should
be evenly distributed among the three
contact points (one hand and two feet
or two hands and one foot).
• Do not stand on the dozer blade and
perform maintenance work. Doing so is
dangerous because of the unsteady
foothold. Use the work bench.
