Maintenance
NOTE : The Selector Switch should be in the "OFF" position while maintenance checks
are being performed. Reference page 13, Figure B.
Hydraulic Filter Element
The hydraulic oil filter is a vital component of the hydraulic system as it filters impurities
and foreign particles to avoid hydraulic component malfunctions.
CAUTION : When the filter element is plugged, hydraulic fluid will by-pass the element,
allowing contamination to enter the hydraulic system. It is recommended that the filter
element be changed every three-(3) months, depending on workload and environmental
conditions. One extra element is furnished with the basic unit. This element should be
installed after the first 40 hours of use. The filter housing is mounted inside the access
door on the machine. Reference: Repair Parts List for reordering instructions and the item
number 7,
Motor Assembly page 46.
Fasteners and Connections
The efficiency and accuracy of the Piranha is dependent upon proper alignment of all
parts. Alignment can only be achieved by keeping the fasteners tight. Check all bolts and
nuts for tightness every 40 hours of operation, or when lubricating the machine. Unless
specified in parts illustrations, torque socket head bolts and hinge pin jam nuts to the
specifications in the table
Recommended Fastener Torque Specifications on page 23.
Check all hydraulic hose and fitting connections for tightness when lubricating the
machine. We recommend you use Loctite hydraulic sealant or an equivalent product on
all connectors.
Check that the hydraulic cylinder clevis is screwed tight on the piston rod each time
machine is lubricated.
Hydraulic Oil Level
The Piranha ironworker is equipped with a dipstick indicator on the fill cap located inside
the access door. The dipstick is marked to help maintain proper fluid level. This should
be checked as part of your normal maintenance cycle.
NOTE : Implement a weekly maintenance program to inspect and lubricate your Piranha.
