8. Connect a source of compressed air to the
air regulator inlet valve on the back of the
machine.
Note: The source of compressed air must
provide a steady supply of clean, dry air at 57
PSI or more, not to exceed 120 PSI.
Exceeding 120 PSI may result in unpredict
-
able operation of the sander and damage to
the pneumatic system.
9. Lift up on the air regulator adjusting knob
(see Figure 13), and turn the knob so that the
air pressure dial reads 57 PSI, then push the
adjusting knob down to lock the setting.

Dust Collection
To connect a dust collection hose:
1. Fit a 4" dust hose over the dust port on top
of the machine, as shown in
Figure 14, and
secure it in place with a hose clamp
.
2. Tug the hose to make sure it does not come
off. Note: A tight fit is necessary for proper
performance.
This sander creates substantial amount of
wood dust while operating. Failure to wear
a respirator rated for wood dust and use an
adequate dust collection system when oper
-
ating this machine can result in short and
long-term respiratory illness.
Minimum CFM at Dust Port: 400 CFM
Do not confuse this CFM recommendation with
the rating of the dust collector. To determine
the CFM at the dust port, you must consider
these variables: (1) CFM rating of the dust col
-
lector, (2) hose type and length between the
dust collector and the machine, (3) number
of branches or wyes, and (4) amount of other
open lines throughout the system. Explaining
how to calculate these variables is beyond the
scope of this manual. Consult an expert or pur-
chase a good dust collection "how-to" book.
