Setting the folding stopper
Mount a fence stop from the end of the fence by
sliding the bolt head at the bottom of the stop
into the top channel of the fence, as shown in
Fig.
4.
The fence stop can be moved to any point along
the fence, and secured by tightening the locking
handle. When not in use, the stop plate can be
flipped upward and out of the way.
NOTE: All locking handles, such as that shown in Fig.
7
can be pivoted out of the way. Simply pull
up on the handle, rotate it to a more convenient position, then release it making sure it seats
itself on the screw.

Air Supply Connection
WARNING
Make sure the locking handle (see Fig.
6
) on the side
of the machine is tightened before connecting the air,
to prevent the boring head from rising suddenly.
Connect your air hose to the nozzle on the
machine´s F.R.L unit, as shown in Fig.
6
. Make
sure your hose fitting is pushed completely onto the
nozzle. Turn on the air.
Check the reading on the pressure gauge – it
should read approximately
6 – 8bar
. If the air
pressure is incorrect, adjust it with the regulator
knob (Fig.
7
) as follows:
Pull up on the air pressure regulator knob, then
rotate it clockwise to increase the air pressure; or
counterclockwise to decrease the air pressure. Make
this adjustment in small increments and allow the
pressure gauge time to react.
When satisfied, push the regulator knob back down.
(For further adjustments of the air system, see under
“Adjustments”)
