Page 14 KM3000 KM4000 Operating Manual
Always stop the machine and lock-out/tag-out the PCU before making
adjustments to controls or machine components. Failure to follow this
safety precaution may result in severe injury.
Always stop the machine using the E-stop button on the PCU. This
removes all pressure from the pneumatic drive motor.
The motor can operate unexpectedly when the air hose is connected.
Close the valve to the pneumatic motor before connecting the air hose.
Avoid damaging the air motor and voiding your warranty by routing
incoming air through the filter and lubricator.
For machines with air motors, if the machine stops moving
unexpectedly, lock out the pneumatic safety valve located at the filter
lubricator assembly before performing any troubleshooting.
2.2.3 KM3000/KM4000 hydraulic power
Table 2-7 lists operating specifications of the hydraulically powered version of the
KM3000 using standard mineral-based hydraulic oil.
A hydraulically powered KM3000 operating with flame retardant, water/
glycol-based hydraulic fluid has operating specifications different from
those listed below. Consult the hydraulic fluid manufacturer data for
operating specifications.
Figure B-2 on page 79 shows the hydraulic schematic.
The hydraulic power unit (HPU) is an electrically-driven piston pump with hori-
zontally mounted high-torque motor. Separate documentation detailing the HPU is
available with the HPU.
TABLE 2-7. HYDRAULIC SPECIFICATIONS
Maximum working pressure: 2,050 psi (140 bar)
