Introduction
Dust Collection
the included dust collection hose assembly has a
21⁄2" adapter for connection to your dust collection
system.
the Model t10252 dust port helps capture
dust from the disc sander on the g1183/g1276
Combination sanders that were manufactured
before august, 2010.
NOTICE
DO NOT operate the Model G1183/G1276

tion system. This sander creates substan-
tial amounts of wood dust while operating.
Failure to use an adequate dust collection
system can result in short and long-term
respiratory illness.
The installation of the dust port requires
that you remove the lower disc guard from
the sander and modify it. Read through
this entire document before beginning the
installation procedure on the next page.

Recommended CFM at Dust Port: 150 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 collector,
(2) hose type and length between the dust col-
lector and the machine, (3) number of branches
or wyes, and (4) amount of other open lines
throughout the system. Explaining how to cal-
culate these variables is beyond the scope of
this manual. Consult an expert or purchase a
good dust collection "how-to" book.
