MKT V-22/HP-380T4, Operating, Maintenance And Parts Manual, Page: 21 / 73

VII. MAINTENANCE AND SERVICE INSTRUCTIONS (CONTINUED)
H. The V-22/HP-380T4 system normally has the hydraulic reservoir, hose
bundle, and hammer lines filled with hydraulic fluid. Whenever the system
has been completely or partially drained (as when a new hose bundle section
is replaced in the hose bundle), the hydraulic lines must be purged of air.
I. Daily maintenance check lists - Check the entire unit prior to and during
startup of each shift.
1. Prior to starting the engine at each shift, check as follows:
a. Make all daily lubrication and preventive maintenance checks indicated in
the engine manufacturer's operating and maintenance manual.
b. Check the hydraulic fluid level before starting the engine. Recheck this
level after filling the lines to be sure it remains in the safe operating range.
Do not operate the unit with the hydraulic fluid level below the gauge.
c. Visually check all hoses for signs of damage or cuts that might cause
hose failure during operation. Be sure all connections are tight,
especially the quick disconnects.
d. Look for any damage to the unit, in general that might cause it to fail
when put into operation.
e. Be sure there is fuel in the tank.
f. Be sure there is cooling fluid in the radiator.
g. Check the V-22 exciter case lube oil level.
h. Check the V-22 clamping jaws for excessive wear, cracks or loose
fasteners. If it is necessary, the removal of the movable jaw is done by
pushing out the 3/4" roll pin. The single vertical roll pin captivates the
movable jaw. The fixed jaw is held tight against the housing with two (2)
1" bolts. Also, operating the V-22 on piling without the jaw shield could
result in jaw damage if the hammer is dropped onto the pile.
i. Check all fasteners to assure that they are tight.
