Flip motor control switch on front panel to the "OFF" position
before plugging the machine in. Make sure the cutting chain is
free from entanglements with other hardware, i.e. do not allow
the cutting chain to be hooked or bound in any way that would
prohibit free movement. When the machine is plugged into a
power source, the red indicator light on the front panel should be
illuminated. At this point, flip the motor control switch to the
"ON" position. If the hydraulic cylinder is at the proper reset
position, nothing should happen, i.e. the hydraulic pump motor
should not run and the cutting chain should not move. If the
hydraulic cylinder has retracted slightly from its reset position (as
might occur during transit or after a long period of storage), the
hydraulic pump motor will run long enough to allow the machine
to reset. Once reset, the hydraulic pump motor will shut off.
(When the unit is plugged in, it is important to allow the cylinder
to go to its reset position, otherwise the valve that operates the
reset function will overheat.) In the event that the hydraulic
pump motor is running and the cutting chain is being pulled into
the mechanism (as would be the case when the cutting chain is
being tightened around the circumference of a pipe), verify that
the overarm (actuating arm) is in its relaxed and retracted
position (not in the actuating position).
