Operation
Payout Operations
The PT-3500 and PT-7500 are designed to offer two methods of payout operations. They can both
be run utilizing a hydraulically assisted payout, where the drum drives the line out. This assisted
other method of payout is a non-assisted payout where the operator utilizes the tensioning
capabilities of the machine. In this method, the machine will hold a set tension on the line, and the
line must be pulled off of the drum at that tension. This method is useful if employing a spider
system to pull the pilot line in or if operating above energized lines.
Hydraulic Assisted Payout:

Perform Start-Up Procedure starting on page
50.

Raise the levelwind to the
upward standby position using
LEVELWIND SETUP screen.

Alternatively, the operator can manually raise
the levelwind to the upward
standby position by pressing
the raise button on the exterior
hydraulic control panel.
If necessary, while outside of the cab, attach
the pulling rope to the tow vehicle.

Get back inside the cab, and turn
off the automatic
levelwind
control
using the door panel
rocker switch.

Select PULL MODE on the
system control display by
pressing and holding the
[SELECT MODE] mode button
for three seconds to toggle through the drive
mode cycles.
This setting is
defaulted to
whatever was
last set for the
system. If the
system is already in PULL MODE, there is no
need to change this setting.
NOTE: Before beginning payout operations, the operator must perform all pre-operation inspections. (See Pre-
Operation Inspection Checklist on page 103.) Pre-operation inspections are important for the safe operation of the
machine and are required under OSHA Regulations.
NOTE: With the system in Pull Mode , the operator
will be able to payout the line at a speed that is
consistent with
walking or driving out the line
with a truck or other off road vehicle. This is
accomplished by using the drive system to drive out
the line with minimal or no tension.
CAUTION: When using pulling mode with minimal
or no tension, excess slack and over spin of the drum
can occur.
