Manually Lowering the Mast
IMPORTANT NOTE: Do not use this procedure
unless it is absolutely necessary. Frequent use of
this procedure could damage the motor shaft.
1. See Figure 3-16 . Remove the motor cover (A).
Figure 3-16. Manually Lowering the Mast
2. Attach a drill chuck firmly to the exposed motor
shaft (B).
3. Using the drill, slowly rotate the motor shaft
counterclockwise to lower mast.
4. Detach the drill chuck and install the motor cover
after the mast is completely lowered.
Lowering the Mast—Power Zone-
DLA (If Equipped)
NOTE: Units with the Power Zone-DLA do not have a
mast switch for the electric winch.
1. Verify Power Zone-DLA controller is powered on.
2. Press the up/down arrows next to the controller
display until the mast screen is shown. See
Figure
3-17 .

IMPORTANT NOTE: Contact a GMP ASD immedi-
ately if the mast hangs up or the winch cable devel-
ops slack.
5. If the unit is going to be moved, rotate the mast so
the lights face the rear of the unit. See
Raising the
Mast—Manual Winch .
Positive Air Shutdown (PAS)
(If Equipped)
See Figure 3-18 . This unit may be equipped with a
positive air shutdown (A) on the air intake. The PAS
system automatically stops the engine if an overspeed is
detected. Engine overspeed can occur if the atmosphere
contains elevated levels of combustible propane or
natural gas.
Figure 3-18. Positive Air Shutdown
The PAS system stops the engine by closing an internal
valve and obstructing intake air. Shutdown is triggered
automatically by an output from the controller or manually
by pulling the T-handle (B).
The reset knob (C) rotates 90° to block airflow. If the knob
is parallel to the pipe centerline (as shown), the valve is
open. If the knob is perpendicular to the pipe centerline,
the valve is closed and airflow is blocked.
Test the PAS
Test the PAS at least once a month to ensure optimal
valve performance. There are two methods:
1. Pull the T-handle. ( NOTE : The valve must be open
before testing.)
2. Press the emergency stop button.
Testing the PAS triggers an actuator, closing the butterfly
valve inside the valve body. An audible click can be
heard when the actuator engages. Confirm that the valve
