MOUNTING THE EXTRACTION ARM
(continued)
Place the other rubber seal around base of the arm
tube. MOUNT THE ARM IN THE VERTICAL POSI-
TION! Rotate the hinge rod so the stop pin is in the
back, and mount the arm (Fig. 4, Item A) on the hinge
rod (Fig. 4, Item B); use the two (1 3/4”) bolts and nuts
in the two vertical connecting holes as shown in the
inset of Fig. 4, leaving a third hole open.
Leave the tape and plastic packaging on the
extraction arm sections until the arm is complete-
ly installed (including mounting the hood). The arm is
spring-balanced to compensate for the weight of the
hood and will spring out quickly if it is not mounted
securely, with the hood in place.
Position one 8” rubber seal (Fig. 5, Item B) and the
flexible hose supplied with the arm (Fig. 5, Item C)
onto the hood end of the arm (Fig. 5, Item A). Put the
last rubber seal on the hood connection. Mount the
hood to the arm.
Remove the plastic and tape from the arm sections.
Snap the “hose running guard” onto the middle hinge
section so the “nose” end faces the base of the arm
as shown in Figure 6.
ADJUSTING THE BALANCE AND
MOVEMENT OF THE ARM
Do not attempt to change the spring tension. Springs
are factory set and once released, cannot be reset in
the field. Balance and movement adjustments are only
made through adjustments of the friction connections.
When installing the arm, adjust the friction connec-
tions to convenient settings. These connections are
located at the base hinge, at the underside of the mid-
dle hinge, and in two directions at the hood hinge.
Refer to the maintenance section of the instruction
manual for the LFA Extraction Arm for details. After
adjusting the friction connections and installing any
lamp options that you have purchased, seal all con-
necting hoses with the rubber seals as described ear-
lier.
INSTALLING COMPRESSED AIR
Connect 90 - 100 psi of clean, dry comprerssed air to
the 1/4” NPT fitting on the front of the machine. If the
pressure relief valve on the tank opens, the com-
pressed air must be regulated to below 100 psi.
