Using the Power Edge LB7 EZ
Adjusting Power Levels
The
EZ
has three power levels. The
EZ
module was designed to allow the user
to select any of the three power levels on the fly with the supplied three position
switch. Level 3 is with the switch towards the tab.
Power Level Confirmation
To confirm the power level that you have selected with your switch, you can do
the following procedure:
1.
Place gear selector in Park with your foot off of the accelerator while
engine is idling
2.
Set the Parking Brake
3.
Place gear selector to reverse, neutral, reverse, then back to park. P-R-N-
R-P
4.
The engine will rev to coincide with the power level selected, revving 3
times for level 3 and so on
Towing
It is recommended that you use the Tow/Haul transmission mode while towing.
This provides torque converter lockup in gears 2-5, which reduces transmission
heat and also raises the shift rpm threshold to keep the rpm’s higher. It is
recommended that you maintain engine rpm above 1800 while towing.
While towing, the
EZ
module allows the engine to pull many grades in the mid
rpm’s rather than having to downshift and pull them in the high rpm’s. This
provides for lower EGT (Exhaust Gas Temperature) with the same power
output. EGT rises significantly with rpm--especially above 2500. It is highly
recommended that you install an EGT gauge while using the Power Edge
EZ
.
It is recommended while towing you use power levels 1 or
2 due to EGT and transmission stress
