1.3 FRONT BLOW TUBE SETTINGS
The front blow consists of two tubes (Figure 13-1 & 2
and Figure 15-1 & 2) instead of the traditional one tube.
The numbers on the left hand side of the tubes correspond to
the chart (Figure 15-3) found on the side of the main control
enclosure.
Setting Up
1.) Determine the width of the job to be run.
2.) Find the numbers on the right-hand side of chart
that correspond with the sheet width.
3.) Set the top (15-1) and bottom (15-2) blow tubes,
using the detent slots, to the respective numbers.
Vacuum adjustment is made at the pump (Figure 16).
Vacuum adjustment requirements should be minimal. Listen
to the feeding at the vacuum wheel to determine if there is too
much vacuum.
1.4 Vacuum Wheel
The vacuum flow is controlled by a solenoid valve
(Figure 11-4 & 17-1). This can be quickly and easily
removed to clean the piston (17-2) by releasing the clamp-
ing springs. Be careful not to damage the piston and
cylinder.
The vacuum wheel (Figure 18-1) is supplied with two
O-rings (18-2) to assist feeding with a positive friction grip.
These O-rings are replaced after removing the guard (18-3)
by removing the two button head screws (18-4) holding it.
