ALWAYS inspect all slings, chains, or cables when lifting components, be sure that they are properly
tied, fastened and balanced before lifting. Be sure that the lifting device is capable of retaining the
weight to be lifted.
NEVER attempt to lift heavy parts by hand when a lifting device should be used.
ALWAYS wear safety glasses when performing any maintenance or repair work on the machine.
NEVER attempt to remove or repair any component, on the machine, while the engine is running.
NEVER leave the machine and/or heavy parts in an unstable position during repair.
ALWAYS keep the machine and work area clear of lubricants and dirt.
ALWAYS use the correct tools for the repair procedures being done on the machine,
ALWAYS use approved parts, that are designed for the machine being repaired. This helps
to ensure maximum service life of the machine.
ALWAYS be sure that all necessary nuts, bolts, snap rings, and other fastening devices, are
removed before using force to remove components.
ALWAYS attach a sign in the machine operators area, stating DO NOT OPERATE when the
machine is being repaired.
ALWAYS observe ALL WARNING AND CAUTION statements given in the Operating Manual and
Service Manual and found on the machine decals.

in Section 4 - MAINTENANCE - in THIS manual.
CHECK, or INSPECT, the following items:
Fuel level.
Engine lubrication oil level.
Engine cooling system coolant level.
Condition of drive belt on engine.
Hydraulic system oil level.
Drum bearing lubrication oil level, in BOTH drums.
Engine inlet air path.
Fluid leaks from engine, fuel or hydraulic system.

Section 3
OPERATION
NOTE: The machine is equipped with an
automatic ether cold start aid. At engine
"cold start", the system will introduce
ether into the fuel intake system to
assist in engine starting. If the engine
fails to start, during a engine "cold start"
[40F, or below] attempt, check and if
needed, replace the ether supply canister
with a "full" replacement canister.
During engine start up, when the ignition
key switch is placed in the "on"
[number 2] position, the system function
monitor display screen [ITEM 26] will
display the machine model number and
then return to the "default screen"
display showing machine speed, front
and rear vibrator speeds [vpm] and
impacts per foot, thereafter.

Section 3
OPERATION
f. AFTER being seated, and BEFORE the
machine is started, ALWAYS securely FASTEN and
TIGHTEN the seat belt across the lap. The operator
MUST remain seated at ALL times during machine
operation. Keep the hands and feet INSIDE the
machine cockpit at ALL times. Allow NO riders on
the machine at ANY time.
g. Do NOT suddenly stop the machine during
operation.
h. BEFORE getting off of the machine, put the
directional/speed control handle [ITEM 1] in the
NEUTRAL position. Put the secondary/parking
brake system control switch [ITEM 5] in the ON
[APPLIED] position. STOP the engine.

GENERAL INFORMATION.
MAINTENANCE SCHEDULE.
GENERAL INFORMATION.
MAINTENANCE.
GENERAL INFORMATION.
MAINTENANCE must be a planned program which
includes periodic machine inspection and lubrication
procedures.
The MAINTENANCE program must be done, based
on the machine OPERATING HOURS, recorded
on the hourmeter, or based on the PERIODIC
SCHEDULE, which is done at time intervals of
weekly, monthly or yearly.
The MAINTENANCE SCHEDULE lists the recommended time intervals between machine maintenance inspections and lubrication procedures. Table
4-1 gives inspection and lubrication information for
the Model C766C and C778B Compactors.
Most service intervals are listed by the HOUR and
PERIODIC time periods. The maintenance
schedule begins with eight [8] hours, or daily,
maintenance intervals and continues through the
2,000 hours, or every two [2] years, maintenance
schedule intervals.
