lection system with a 3" adapter.

must be adjusted in/out so there is not more

Dust collection
DO NOT use the Model H7507 without an ade-
quate dust collection system. An attached
router will create substantial amounts of
wood dust while operating. failure to use a
dust collection system can result in short
and long-term respiratory illness.
Recommended cfM at Dust port: 225 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.
the Model h7507 features a clear 3" plastic guard
that can be connected to a dust collector or a dust
collection system.
19. Center the guard over the table opening and
attach the guard assembly to the top of the
fence boards with the two provided wood
screws, as shown in
figure 29.
