Test The Pas; Reset The Pas; Lower Radiator Hose Heater (If Equipped); Tandem Tow (If Equipped) - Generac Power Systems MAGNUM MLT6SM Owner's Manual

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
is closed by verifying that the knob has rotated perpen-
dicular to the pipe centerline. If valve does not close, con-
tact Generac Mobile Products Technical Support.

Reset the PAS

IMPORTANT NOTE: Before resetting the PAS, turn
the control power switch OFF (O). This will prevent
unexpected engine start-up during the procedure.
1. Rotate the reset knob and hold it in place while
pulling the T-handle until reset knob rotates coun-
terclockwise into plunger detent. An audible "click"
indicates the reset knob has seated properly.
2. Verify that the reset knob is parallel to the intake
pipe centerline.
3. Release T-handle, and then release reset knob.
The reset knob should remain parallel to the intake
pipe centerline.
Lower Radiator Hose Heater
(If Equipped)
The lower radiator hose heater is designed to prevent
engine coolant from freezing in extreme cold weather
conditions. While the heater is designed to be operated
overnight if necessary, 2–5 hours of heating just prior to
starting is usually sufficient for proper engine starting.
NOTE: Use the lower radiator hose heater only in its
designated location. Incorrect use can damage the
engine.
Proceed as follows when operating a unit equipped with
a lower radiator hose heater.
1. Verify the unit is level to maintain correct orienta-
tion of the heater while it is in operation.
2. Verify the cooling system is full of the correct
mixture of water and engine coolant before each
heater use.
Owner's Manual for MLT6SM/6SK Light Tower
3. Use only an undamaged, outdoor rated, three-
prong grounded 120VAC extension cord with a
minimum amperage rating of 10A. Connect the
cord to a properly grounded 120VAC GFCI outlet.
4. Before starting the engine, unplug the extension
cord from the power first, then unplug the heater
cord set from the extension cord.

Tandem Tow (If Equipped)

See Figure 3-19. The tandem tow hitch option (A) allows
the operator to tow a second MLT6 Light Tower in series
behind the unit equipped with the hitch.
IMPORTANT NOTE: Never tow more than two units
at once.
Connect any trailer wiring to the unit in front (B).
•
Inspect for proper operation of the directional and
brake lights.
Connect the towing chains to the tie down locations
•
(C).
Avoid sharp turns when towing. Do not cross any
•
obstacles more than 12 in (30.5 cm) deep.
• Tandem tow speeds:
a. Paved highway—45 mph (72 km/h)
b. Graded gravel—25 mph (40 km/h)
c. Cross country—10 mph (16 km/h)

Telemetry (If Equipped)

The digital telemetry option enables the operator to
remotely monitor the unit fuel level. A transmitter inside
the engine compartment sends real time equipment
status information to the user via cellular or satellite
connection.

Spark Arrester (If Equipped)

A spark arrester, installed on the unit exhaust, may be
required by code in certain municipalities. Contact the
local authority having jurisdiction to determine if a spark
arrester must be installed on the unit before operation.
