WARNING:
The boring head may swing up rapidly. Keep hands clear and do not allow anyone
to stand near the boring head area when raising or lowering it.
When the boring head reaches horizontal position, tighten the locking handle.
WARNING
The locking handle should always be tightened, except when tilting the boring head.
13.5.6 90 Degree Stop
The 90 degree stop for the boring head has been factory set and should require no adjustment.
As the machine receives extensive use, however, you may wish to check this setting and if
necessary adjust as follows:
• Open the front or rear door.
• Loosen the hex nut (A, Fig. 11)
• Rotate the stop screw as needed, until the boring
head will attain 90 degrees when the boring head
contacts the stop screw.
• Tighten the hex nut A
13.5.7 Horizontal Stop
• The horizontal stop for the boring head is
controlled by the nut located on the cylinder (C,
Fig. 11). The nut regulates how far the cylinder
rod can protrude, and thus controls where the boring head comes to a stop when pivoted to
horizontal position.
• Rotate the nut as needed until the boring head is level (0 degrees) at horizontal position.
13.5.8 45 Degree Stop
The 45 degree stop for the boring head has been factory set and should require no adjustment.
As the machine receives extensive use, however, you may wish to check this setting and if
necessary adjust as follows:
The angle pin ( Fig. 12) should be pushed in
completely. (You may have to slightly loosen the
socket head cap screw on the angle pin to allow the
angle pin to move)
• Loosen the hex nut on the 45 degree stop screw
(Fig. 12)
• Turn the stop screw until the 45 degree angle is
obtained. Check this setting by pivoting the head
down until the stop screw contacts the angle pin.
The angle can be read on the angle gauge (Fig.
12)
Make further turns of the stop screw if needed, then tighten the hex nut on the stop screw.
When using the 45 degree stop, always tighten the locking handle (Fig. 12)
