Circuits

Battery Fluid
WARNING
Before inspecting the electrical system,
be sure either to turn off the battery
switch or to disconnect the (-) terminal
of the earth cable. Otherwise, a short-
circuit could cause a fire.
Ensure good ventilation when charging
the battery. The use of open flames is
strictly prohibited. Hydrogen gas may
also catch fire.
Battery fluid is diluted sulfuric acid. It
can blind you or burn your eyes or skin.
Wear goggles and gloves when handling
battery fluid. Should the fluid be
deposited on your skin, wash with a
large quantity of fresh water and seek
treatment from a doctor.
1) If operation continues with insufficient
battery fluid, the battery will be destroyed.
Check the fluid level periodically. If the
level is lower than specified, resupply
battery fluid (available in the market) up to
the upper limit of the battery.
(Battery fluid tends to evaporate in high
temperatures, especially in summer. In
such cases, inspect the battery earlier than
specified.)
2) If the engine speed will not rise and the
engine cannot be started, measure the
specific gravity with a pycnometre (avail-
able in the market).
The specific gravity of the fluid when fully
charged is over 1.27(at 20°C).
Fluid with a specific gravity of below 1.24
needs charging. If the specific gravity
Pagina 39
cannot be raised by charging, the battery
must be replaced.
NOTICE
The capacities of the standard
alternator and the recommended
battery assume only the power
necessary for regular operation.
If the power is also used for inboard
lighting or other purposes, the
generating and charging capacities
may be insufficient. In such cases,
consult your Yanmar dealer or
distributor.
4.3.3 Inspection Every 250 hours.
(1) Replace the engine oil and the
clutch lube oil.
After the second oil change, the engine oil
should be replaced after every 250 hours.
(2) Replacing the Engine Oil and Lube
Oil Filter
(See 4.3.1(1))
(3) Adjusting the Remote Control Cable
The various control levers on the engine
side are connected to the remote control
lever by the remote control cable. The
cable will become stretched and the
attachments loose after long hours of use
causing deviation. It is dangerous to
control operation under these conditions,
and the remote control cable must be
checked and adjusted periodically.
A) Adjusting the Governor Remote Control
Cable
Check to see that the control lever on the
engine side moves to the high speed bolt
position and low speed bolt position when
the remote control lever is moved to
H (high speed) and L (low speed) respec-
tively.
When there is deviation, loosen the
bracket for the remote control cable on the
engine side and adjust.
