Operations - Powermatic PM3000B Operating Instructions And Parts Manual

3. Using a 14mm open wrench, loosen hex nut
(B, Figure 8-13). This will allow hex cap screw
to be turned and saw blade to be adjusted
lower.
4. Use height adjust handwheel (B, Figure 8-1),
to lower saw blade all the way.
The zero-clearance insert can now be placed in
table opening without contacting blade.
Figure 8-13
Never use a zero-clearance
insert with saw blade in tilted position. Never
operate saw without blade guard, riving knife
and anti-kickback pawls for operations where
they can be used.
When the standard insert is to be used again, the
saw blade must be readjusted as follows:
5. With the height adjust handwheel (B, Figure 8-
1), adjust blade height until top of saw blade is
1/8" below top of table.
6. The blade depth stop screw (A, Figure 8-13)
should be resting against the trunnion. Verify
this; then tighten hex nut (B, Figure 8-13).
7. Reinstall standard insert, pawls and blade
guard.

9.0 Operations

Familiarize yourself with the location and operation
of all controls and adjustments and the use of
accessories such as miter gauge and rip fence.
Note: The following figures are general in nature
and may not show your particular saw model.
9.1 Kickback prevention
Serious injury can result from kickbacks which
occur when a workpiece binds on the saw blade or
binds between the blade and rip fence or other
fixed object. This binding can cause the workpiece
to lift up and be thrown toward the operator.
Listed below are conditions which can cause
kickbacks:
Confining the cutoff piece when crosscutting

or ripping.
Releasing

operation or not pushing workpiece all the
way past saw blade.
Not using splitter/riving knife when ripping or

not maintaining alignment of splitter/ riving
knife with saw blade.
Using dull saw blade.

Not maintaining alignment of rip fence so that

it tends to angle toward rather than away
from saw blade front to back.
Applying feed force when ripping to the cutoff

(free) section of workpiece instead of the
section between saw blade and fence.
Ripping wood that is twisted (not flat), or

does not have a straight edge, or has twisted
grain.
To minimize or prevent injury from kickbacks:
Avoid conditions listed above.

Wear a safety face shield, goggles, or safety

glasses.
Do not use miter gauge and rip fence in the

same operation unless provision is made by
use of a facing board on the fence, to allow
the cutoff section of workpiece to come free
before the actual cut begins (See Figure 9-
8).
As the machine receives use, the operation

of the anti-kickback pawls should be checked
periodically (Figure 9-1). If the pawls do not
stop the reverse motion of a workpiece,
resharpen all the points.
Where possible, keep your face and body out

of line with potential kickbacks, including
when starting or stopping the machine.
Dull, badly set, improper, or improperly filed

cutting tools, and cutting tools with gum or
resin adhering to them can cause accidents.
Never use a cracked saw blade. The use of a
sharp, well maintained, and correct cutting
tool for the operation will help avoid injuries.
