4.12 CHARGING BATTERY _____________________________________________________
1. Refer to Section 4.10. Read the Battery and
Charger’s manual for specific instructions.
2. Whenever possible, remove the battery from the
tractor before charging. If battery is not sealed,
check that the electrolyte covers the plates in all the
cells.
3. Make sure the charger is “Off”, then connect the
charger to the battery terminals as specified in the
charger’s manual.
4. Always turn the charger “Off” before disconnecting
charger from the battery terminals.
4.13 HYDRAULIC HOSES _______________________________________________________
1. Always lower implements to ground, disengage all
drives, engage parking brake, stop engine and
remove key before inspecting or disconnecting
hydraulic lines or hoses.
2. Check visible hoses and tubes daily. Look for wet
hoses or oil spots. Replace worn or damaged hoses
and tubes before operating the machine.
3. The replacement tube or hoses must be routed in
the same path as the existing hose, do not move
clamps, brackets and ties to a new location.
4. Thoroughly inspect all tubes, hoses and connections
every 300 hours.
IMPORTANT:
The hydraulic system can be
permanently damaged if the oil becomes
contaminated.
Before disconnecting any hydraulic
component, clean the area around the fittings and
the hose ends to keep impurities out of the system.
a. Before disconnecting any hydraulic component,
tag or mark the location of each hose then clean
the area around the fittings.
b. As you disconnect the component, be prepared
to assemble plugs or caps to the hose ends and
open ports. This will keep impurities out of the
hydraulic system and also prevent oil spills.
c. Make sure “O” rings are clean and hose fittings
are properly seated before tightening.
d. Keep the hose from twisting. Twisted hoses can
cause couplers to loosen as the hose flexes dur-
ing operation resulting in oil leaks.
e. Kinked or twisted hoses can restrict the oil flow
causing the system to malfunction and the oil to
overheat and also lead to hose failure.
WARNING
Charge battery in a well ventilated area. Batteries
generate explosive gases. To prevent an explosion,
keep any device that may create sparks or flames
away from the battery.
To prevent injury, stand away from battery when the
charger is turned on. A damaged battery could
explode.
!
WARNING
To prevent serious injury from hot, high pressure oil,
never use your hands to check for oil leaks, use paper
or cardboard.
Hydraulic fluid escaping under pressure can have
sufficient force to penetrate skin. If fluid is injected into
the skin it must be surgically removed within a few
hours by a doctor familiar with this form of injury or
gangrene may result.
