5.2 MAINTENANCE
By following a careful service and maintenance pro-
gram on your machine, you will enjoy many years of
trouble-free use.
5.2.1 HYDRAULIC SYSTEM INSPECTION
A hydraulic system provides power to move the ma-
chine. The system consists of an electrically powered
pump, reservoir, lines, hoses, directional valves, mo-
tors and cylinders. To maintain the integrity of the
system and provide a safe working environment for
the operator, it is important that a daily inspection be
done to make sure that the entire system and all com-
ponents are in good working condition.
When inspecting the hydraulic system and compo-
nents, follow this procedure:
1. Place all controls in the OFF or neutral position.
2. Turn power OFF at the master panel and lock-out
before starting the inspection.
3. Inspect all hydraulic components looking for:
a. Leaks.
b. Damaged hoses or lines.
c. Damaged or leaking cylinders.
d. Leaking motors or îttings.
e. Damaged or leaking solenoid and directional
valves.
f. Leaking pump or îttings.
4. Tighten any leaking îttings and replace any dam-
aged components.
5. Change the hydraulic oil and îlter every 500 hours
or annually per the Service schedule. Change
more frequently if operating in harsh conditions
such as extreme heat or cold, extreme dust or dirt,
and/or extreme humidity.
5.2.2 ELECTRIC SYSTEM INSPECTION
Electricity provides power to all systems on the Con-
veyor. To maintain the integrity of each system and
provide a safe working environment for the operator,
it is important that a daily inspection be done to make
sure that all systems and components are in good
working condition. To provide a safe working environ-
ment, have a licensed electrician provide power to
the machine.
When inspecting the electrical system and compo-
nents, follow this procedure:
1. Place all controls in the OFF or neutral position.
2. Turn power OFF at the master panel and lock-out
before starting the inspection.
3. Inspect all electrical components looking for:
IMPORTANT
Do not operate the machine unless the
master panel is equipped with a lock-out
device. Always engage lock-out device
before performing any maintenance
work. Lock-out devices are available
from your dealer or the factory.
a. Physical damage. (Includes all components:
starters, switches, enclosures, as well as
plugs).
b. Frayed or loose wires.
c. Cut or cracked insulation.
4. Replace any damaged components immediately.
5. Be sure all components are grounded.
6. Be sure there is not water or moisture in any junc-
tion box or enclosure. Dry the components before
turning power on. Be sure that all compartments
seal properly when closed.
