Changing Rolling-Filter Timing - Grizzly G0648 Owner's Manual

Changing Rolling-
Filter Timing
as the rolling-type filter becomes clogged, the
EXhauSting tiME and rolling tiME should
be set to advance the rolling type filter as to
expose just enough filter paper so that a good
working CFM is maintained. this is accomplished
by unrolling just enough filter paper to maintain
adequate suction at the point of welding. the
general idea is to initially find the point at which
the filter paper begins to clog and suction begins
to drop off. When you determine that point, both
(or either) the EXhauSting tiME or FiltEr
rolling tiME settings should be adjusted to
restore acceptable suction.
:
Exhausting Time
this is the time interval
between the filter advance events. the time inter-
vals can be set at 30, 45, 60, 120, 180, and 240
minutes. For example, if 45 minutes is selected,
the filter will advance every 45 minutes for the
duration you have selected below under FiltEr
rolling tiME.
Filter Rolling Time: this is the time duration the
filter is allowed to advance, which exposes new
filter paper. the advance time can be set at 10,
15, 20, 25, 30 or 40 seconds. For example, the
greater the filter rolling time, the more fresh filter
paper is exposed.

To change the rolling-filter timing:
1.
Stop the machine.
2. refer to the Rolling Filter Consumption
Chart on page 21 to select your needed time
values.
3. open the control panel door (Figure 10).
4. Slide the nor/SEt switch (Figure 10) to the
SEt position.

5.
press the time Setting buttons on the control
panel to your new time settings.
6. Slide the nor/SEt switch to the nor posi-
tion.
7. Close the control panel door.
