INSTALLATION
Installation of the EZ Loader is a simple process; however, certain precautions must be taken to ensure years of
trouble free service. The EZ Loader requires clean, dry, compressed air to operate properly. A fi lter and regulator with
a pressure gauge should be installed on an air line in the installation area before initially charging the system for use.
Before you begin, locate and identify the pneumatic components detailed in Figure 6. These components will be
referred to in the Installation and the Set-Up procedures. Make sure you understand the function of each component
before proceeding.
Air Chuck - The air chuck is supplied the EZ Loader and is used to charge the EZ Loader with air. The air chuck
body is supplied with 1/4 inch female pipe threads and must be attached to the end of the air line extending from the
fi lter/regulator.
Air Gauge - The air gauge, Figure 7, indicates the EZ Loader’s internal system
pressure. Green identifi es the initial pressure range for the EZ Loader in the raised
position. The initial system pressure should be between 10 psi (0.7 bar) and 60 psi
(4.1 bar). Yellow identifi es the operation pressure range when the EZ Loader is fully
loaded and collapsed. The maximum operational pressure is 135 psi (9.3 bar). Under
no circumstance should be EZ Loader be operated in the red range above 135 psi (9.3
bar).
Purge Valve - The purge valve is a manual one way valve used to release air from
the EZ Loader. Turning the valve counter-clockwise opens the valve and releases air
from the system. Turn the valve clockwise to close. The valve should be closed with
fi nger tight pressure. DO NOT use a wrench to close the valve. Leakage may occur if
over-tightened.
Tank Valve - The tank valve is a one way valve used to charge the EZ Loader with
air. The end of the tank valve is designed to mate with the air chuck. Pressing the air chuck against the end of the
tank valve allows air to enter the system.
EZ Adjust Knob - The EZ Adjust capacity adjustment knob allows the operator to change the collapsed capacity
of the EZ Loader without adding or removing air from the system. The knob’s three (3) positions are identifi ed in
Figure 8.
Light Weight Position - is also the air charge/discharge position. Always turn the EZ Adjust
knob to this position before adding or removing air from the system. The Light Weight
