ZUMA BREWER CAST ALUMINUM ARM UPGRADE INSTRUCTIONS
1. Remove the old Zuma brewer arms.
a) Open the brewer and remove the brew chamber.
b) Rotate the T-bar 180° to allow the H-frame to open completely.
c) Make sure the crank arm is at about the 5 o'clock position.
d) Remove the two 'C'-clips that secure the wipe arm and unwipe
arm shafts in place. These clips are located on the front of the
brewer mainframe, just below the brew cylinder (Figure 1).
e) From the front of the brewer, push the two arm shafts out the back
of the brewer. These will free the two older arms (Figure 1).
f)
From the top of the brewer, push the arms out the bottom of the
brewer.
g) Once done, the wipe arm spring and two plastic bushings will fall
out of the brewer. The two bushings can be discarded, but the
spring is still required.
2. Install the new Zuma brewer arms.
a) Position the spring onto the wipe arm boss (round protrusion) as
illustrated (Figure 2).
b) Slide the wipe arm into the brewer from the bottom.
c) Secure the wipe arm (and spring) in place by installing the wipe
arm shaft.
d) Secure the wipe arm shaft in place by installing the 'C'-clip.
e) Slide the spring hook tool (p/n – M027019) through the top right of
the brewer towards the wipe arm spring (Figure 3).
f)
Hook the smaller end of the wipe arm spring and pull upwards on
the tool. This will rotate the spring into position and allow you to
secure the end of the spring (small hook) onto the inner part of the
wipe arm (Figure 3).
g) Turn the brewer shaft until the crank arm is in the 9 o'clock
position.
h) Slide the unwipe arm into the brewer from the bottom.
i)
Place the loop of the spring onto the boss (round protrusion) of
the arm. You may need to use a small screwdriver to lift the spring
onto the boss.
j)
Secure the unwipe arm (and spring) in place by installing the
unwipe arm shaft.
k) Secure the unwipe arm in place by installing the 'C'-clip.
l)
Turn the brewer shaft until the crank arm is in the 5 o'clock
position.
m) Slide the spring hook tool through the top left of the brewer
towards the unwipe arm spring (Figure 4).
n) Hook the end of the unwipe arm spring and pull upwards on the
tool. This will allow you to secure the end of the spring (small
hook) onto the inner part of the unwipe arm (Figure 4).
o) Re-install the H-frame and the brew chamber.
p) Test the brewer to verify the operation of the arms and the tension
on the brew chamber. Make any necessary adjustments.
