Recommended preventive maintenance will contrib-
ute to the long life and dependability of the truck and
its components. The use of proper lubricants and the
performance of checks and adjustments at the rec-
ommended intervals is most important.
Lubrication requirements are referenced to the lube
key found in the Lubrication Chart (page P2-5). For
detailed service requirements for specific compo-
nents, refer to the service manual section for that
component (i.e. Section H for suspensions, Section L
for hydraulic system, etc.).
Refer to the manufacturer's service manual when
servicing any components of the General Electric
system.
Refer to the engine manufacturer's service manual
when servicing the engine or any of its components.
The service intervals presented here are in hours of
operation. These intervals are recommended in
lieu of an oil analysis program which may deter-
mine different intervals. However, if the truck is
being operated under extreme conditions, some or
all, of the intervals may need to be shortened and the
service performed more frequently.
The 830E truck is equipped with an automatic lubri-
cation system. The initial setup for this system pro-
vides for nominal amounts of lubricant to be
delivered to each serviced point. The lubrication
injectors can be adjusted to vary the amount of lubri-
cant delivered. In addition, the timer for lubrication
intervals is normally adjustable. For adjustments to
these devices, refer to Automatic Lubrication System
later in this manual.

Lubrication and Service
HYDRAULIC TANK SERVICE
There are two sight gauges on the side of the
hydraulic tank. With the engine stopped, key switch
OFF, hydraulic system bled down and body down, oil
should be visible in the top sight gauge. If hydraulic
oil is not visible in the top sight gauge, follow Adding
Oil instructions below.
Adding Oil
Keep the system open to the atmosphere only as
long as absolutely necessary to lessen the chances
of system contamination.
Service the tank with clean Type C-4 hydraulic oil
only. All oil being put into the hydraulic tank must be
filtered through filters rated at three microns.
1. With the engine stopped, key switch OFF,
hydraulic system bled down and body down,
check to see that hydraulic oil is visible in the
top sight gauge.
2. If hydraulic oil is not visible in the top sight
gauge, remove the tank fill cap. Add clean, fil-
tered C-4 hydraulic oil (Lubrication Chart, Lube
Key "B") until oil is visible in the top sight gauge.
3. Install the fill cap.
4. Start the engine. Raise and lower the dump
body three times.
5. Repeat Steps 1 through 4 until oil is maintained
in the top sight gauge with engine stopped,
body down, and hydraulic system bled down.
WHEEL MOTOR SERVICE
Due to differences in gear ratio and component evo-
lution/design, wheel motor service intervals may be
unit number and/or mine specific. Because of the
wide variety of factors involved, it is necessary to
consult your area Komatsu representative for all
wheel motor service intervals and instructions. Gen-
eral intervals for oil service and sampling are listed in
the interval charts.
COOLANT LEVEL CHECK
Inspect the coolant sight gauge. If coolant cannot be
seen in the sight gauge, it is necessary to add cool-
ant to the system before truck operation. Refer to the
procedure below for the proper filling procedure.
