VII. MAINTENANCE AND SERVICE INSTRUCTIONS (CONTINUED)
1. Check the hydraulic fluid level on the HP-380T4 tank gauge before
and during operation of the V-22/HP-380T4 system.
DO NOT
OPERATE THE V-22/HP-380T4 SYSTEM IF THE HYDRAULIC
FLUID REGISTERS BELOW THE TANK FLUID GAUGE.
2 In normal, safe operation of the V-22/HP-380T4 system, the
hydraulic fluid temperature should remain in its typical range of 115
degrees Fahrenheit to 165 degrees Fahrenheit. This temperature
can be read on the thermometer located on the control panel.
CAUTION: IF THE HYDRAULIC OIL TEMPERATURE BECOMES
EXCESSIVE (ABOVE 180 DEGREES FAHRENHEIT) STOP
OPERATIONS AND CONSULT WITH THE NEAREST
FACTORY AUTHORIZED SERVICING DISTRIBUTOR.
E. Make a daily check of all hoses in the hydraulic hose bundle for cuts or other
damage. Hoses are sometimes cut or bruised by dragging them across pile
heads while setting the V-22 hammer. Stop V-22 hammer operations that
may cause damage to the hoses and redirect the hose bundle to avoid
dragging and damage. Damaged hose sections must be replaced to
eliminate failure and down time during operations.
F. Inspect the V-22 hammer for normal hanging posture and loosened
fasteners, particularly on the suspension and clamp assemblies before and
during operation.
SAFETY WARNING: STAND AWAY FROM THE PILE AND FROM
BELOW THE V-22 DURING VIBRATING
OPERATIONS. ANY UNOBSERVED,
UNCORRECTED, LOOSE NUT OR OTHER
FASTENER MAY FALL.
G. Assure that the proper lube oil level is maintained in the V-22 exciter case. If
the level of oil is above the sight gauge or the lube oil volume is increasing
this may be an indication that the hydraulic motor is leaking hydraulic fluid
through the motor drive shaft seal. Any seal leakage must be corrected
immediately. The mixture of hydraulic oil and lube oil is not a lube problem
but the increasing level will add load to the rotating eccentrics and cause
excessive foaming.
The lube oil in the V-22 exciter case should be changed after every 50 hours
of driving time.
