PRECAUTIONS FOR MAINTENANCE
When the strainer is located in
the oil filler, the strainer must not
be removed while adding oil.
When adding oil or checking the
oil level, check that the oil is at
the correct level.
After greasing up, always wipe
off the old grease that was
forced out.
When changing the oil or filter,
check the drained oil and filter
for any signs of excessive metal
particles or other foreign
materials.
When removing parts containing
O-rings, gaskets or seals, clean
the mounting surface and replace
with new sealing parts.
When washing the machine,
ensure that water does not get
onto the alternator.
Special measuring apparatus is
needed for testing hydraulic
pressure.
Thoroughly wash the machine. In
particular, be careful to clean the
filler caps, grease fittings and the
area around the dipsticks. Be
careful not to let any dirt or dust
into the system.
When check an open cover there
is a risk of dropping things in.
Before removing the covers to in-
spect cover, empty everything
from your pockets. Be particularly
careful to remove wrenches and
nuts.
When working on the sea shore,
carefully clean all electrical equip-
ment to ensure that is does not
corrode.

parts of the machine.
