For Your Own Safety, Read Instruction
Manual Before Operating this Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of impor-
tance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgement.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
This symbol is used to alert the user to useful information about
proper operation of the machine.

Safety Instructions for Line Boring Machines
Like all machinery there is potential danger
when operating this machine. Accidents
are frequently caused by lack of familiarity
or failure to pay attention. Use this machine
with respect and caution to decrease the
risk of operator injury. If normal safety pre-
cautions are overlooked or ignored, seri-
ous personal injury may occur.
No list of safety guidelines can be com-
plete. Every shop environment is different.
Always consider safety first, as it applies
to your individual working conditions. Use
this and other machinery with caution and
respect. Failure to do so could result in
serious personal injury, damage to equip-
ment, or poor work results.

Note: Generally, slight differences of drilling
depth from one bit to another is acceptable.
However, if drilling depth adjustment of a bit
is required, refer to Adjusting Boring Bit
Height on Page 19.
NOTICE
This line boring head is designed to drill only
wood products. Drilling any other material
may damage the head and machine.
Note: Make sure the boring bits to be installed
match the rotation direction of each chuck, as
shown in the information circle above the
chuck on the boring head assembly.
For example, the chuck shown in Figure 11
rotates to the right (as viewed from above).
This is shown by the letter "R" in the informa-
tion circle. The boring bit is also 64mm on
center from the middle or number "0" boring
bit, as shown by the number in the top of the
information circle.

Make sure the hold-downs exert enough
pressure to keep the workpiece in place
against the rotational force of the boring
bits. Otherwise, the workpiece may move
during the boring operation, resulting in a
drilling line that is out of alignment.
