3.0 Safety warnings
1. Read and understand entire owner's manual
before attempting assembly or operation.
2. Read and understand the warnings posted on
the machine and in this manual. Failure to
comply with all of these warnings may cause
serious injury.
3. Replace warning labels if they become
obscured or removed.
4. This lat he is designed and intended f or use by
properly trained and experienced personnel
only. If you a re no t fa miliar with the pro p er a nd
safe operation of a lathe, do not use until
proper training and knowledge have been
obtained.
5. Do not use this lathe for othe r than its intended
use. If used for other purposes, Powermatic
disclaims any real or implied warranty and
hold s itself harmles s from a ny injury t hat may
result from that use.
6. Always wear approved safety glasses or f ace
shields while using this lathe. Everyday
eyeglasses only have impact resistant lenses;
they are not safety glasses.
7. Before operating this lathe, remove tie, rings,
watches and other jewelry, and roll sleeves up
past the elbows. Remove all loose clothing
and confine long hair. Non-slip footwear or
anti-skid floor strips are recom mended. Do not
wear gloves.
8. Wear ear protectors (plugs or muffs) during
extended periods of operation.
9. Some dust created by power sanding, sawing,
grinding, drilling and other construction
activities contain chemicals known to cause
cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
• Lead from lead based paint.
•
Crystalline silica from bricks, cement and
other masonry products.
•
Arsenic and chromium from chemically
treated lumber.
Your risk of exposure varies, depending on
how often you do this type of work. To reduce
your exposure to these chemicals, work in a
well-ventilated area and work with approved
safety equipment, such as face or dust masks
that are specifically designed to filter out
microscopic particles.
10. Do not operate this machine while tired or
under the influence of drugs, alcohol or any
medication which may impair your judgment.
11. Make certain switch is in OFF position before
connecting machine to power supply.
12. Make certain machine is properly grounded.
13. Make all machine adjustments or maintenance
with machine unplugged from power source.
14. Remove adjusting keys and wrenches. Form a
habit of checking to see that keys and
adjusting wrenches are removed from the
machine before turning it on.
15. Keep safety guards in place at all times when
machine is in use. If removed for maintenance
purposes, use extreme caution and replace
the guards immediately after completion of
maintenance.
16. Check damaged parts. Before further use of
the machine, a guard or other part that is
damaged should be carefully checked to
determine that it will operate properly and
perform its intended function. Check for
alignment of moving parts, binding of moving
parts, breakage of parts, mounting and any
other conditions that may affect its operation.
A guard or other part that is damaged should
be properly repaired or replaced.
17. Provide for adequate space surrounding work
area and non-glare, overhead lighting.
18. Keep floor around machine clean and free of
scrap material, oil and grease.
19. Keep visitors a safe distance from the work
area. Keep children away.
20. Make your workshop child proof with padlocks,
master switches or by removing starter keys.
21. Give your work undivided attention. Looking
around, carrying on a conversation and “horseplay” are careless acts that can result in
serious injury.
22. Maintain a balanced stance at all times so that
you do not fall against t he spindle, workpiece
or other moving parts. Do not overreach or use
excessive force to perform any machine
operation.
23. Use the right tool at the correct speed and
feed rate. Do not force a tool or attachment to
do a job for which it was not designed. The
right tool will do the job better and more safely.
24. Use recommended accessories; improper
accessories may be hazardous.
25. Keep turning tools sharp and clean for the best
and safest performance, and position tools
properly in relation to the workpiece.
5
26. Turn off the machine before cleaning. Use a
brush or compressed air to remove chips or
debris — do not use your hands.
33. Make sure all locking handles are tight to
prevent creeping of headstock, tailstock or tool
post.
27. Do not stand on the machine. Serious injury
could occur if the machine tips over.
28. Never leave the lathe running unattended.
Turn the power off and do not leave the
machine until spindle stops completely.
29. Remove loose items and unnecessary work
pieces from the area before starting the
machine.
30. Don’t use in dangerous environment. Don’t
use power tools in damp or wet locatio ns, or in
the presence of flammable liquids or gases.
31. Check workpiece carefully for splits, knots or
other obstructions which may cause a safety
risk while turning.
32. Adjust tool support to proper height and
position for the work. Rotate workpiece by
hand to check clearance with tool support.
Familiarize yourself with the following safety notices used in this manual:
This means that if precautions are not heeded, it may result in minor injury and/or possible
machine damage.
34. Turn off lathe before adjusting tool rest.
35. S elect appropriate speed for the turning job at
hand. Start at low speed and allow lathe to
ramp up to operating speed.
36. Never stop a rotating workpiece with your
hand.
37. If reversing spindle rotation, make sure face
plate or vacuum chuck is secured with t he set
screws.
38. If gluing up a workpiece, always use highquality glue of the type necessary for that
particular workpiece.

the two positions, plunger will engage. (Swing
lamp holder away for guard clearance.)
7.9 Air/vacuum system
Connecting pressurized air to the lathe allows use
of the air blow gun and the vacuum chuck.
See Figures 12 and 13.
1. Connect blow gun hose (A, Figure 12) to t he
tee connector.
2. Connect your incoming air supply (90 psi) to
the quick connect coupler (B).
3. Attach vacuum adaptor (C) to hose (D) and
push adaptor into spindle.

7.10 Optional accessories
The following items are optional and purchased
separately. See your Powermatic dealer for
information. If you did not purchase an optional
accessory, proceed to section 7.11.
The optional 20-inch bed extension is available in
two configurations: Bed Extension only (p/n
6294905) and Bed Extension Kit with elevating and
swing-away function (p/n 6294900). The bed
extension can be installed to upper or lower sets of
holes.
7.10.1 20-inch Bed Extension
Installing Bed Extension only (p/n 6294905)
Tools required:
10mm hex key
1. Slide tailstock away from edge of bed.
2. Have an assistant hold bed extension flush to
end of lathe bed, and insert f our screws with
washers (provided with bed extension). Snug
screws just enough to hold bed extension to
lathe bed.
Figure 12
4. Install support bracket (E, Figure 13) with
knurled screw. This prevents adaptor from
backing out during spindle rotation.
3. Adj ust extension bed to lathe bed, aligning the
surface and the inside ways as closely as
possible.
IMPORTANT: Top surface of bed extension
must be flush with surface of lathe bed, and
inside ways must be aligned, to allow smooth
movement of tailstock across joint.
4. Slide tailstock over joint where beds meet, so
that clamping nut is centered over joint (Figure
14). Lock tailstock clamping handle; this will
align the beds.
5. Tighten screws in extension bed.
6. Unlock tailstock and slide it back and forth to
test smoothness of joint.

7. Unscrew stop bolt from lathe bed (Figure 15),
and insert it into hole at end of bed extension.

7.10.2 20” Bed Extension Kit (6294900)
Tools required:
8mm hex key
10mm hex ke y
Strai ght Edge
1. Slide tailstock away from edge of bed.
2. Place a straight edge against bed and raised
area of leg (Figure 16). These two areas
should be flush. If they are not, support the
lathe (with fork lift, hoist, etc. – USE
CAUTION!) and loosen the screws holding leg
to bed. Nudge leg as needed, then retighten
screws firmly.
3. Install 20-inch bed extension in the same
manner as described in section 7.10.1.
Figure 16
4. Install elevating system (Figure 17) to bed
extension with four 3/8" screws and washers,
and to lathe leg with three 1/2” screws and
washers (A, Figure 17). Note that top screw is
installed from inside the leg and secured with
the nylon nut (B). Refer to exploded view,
section 17.5.1 if clarification is needed.
5. Install handwheel and tighten setscrew.
Figure 17
Remove screws in bed extension to swing away
the bed, or to move bed to lower set of holes. Note:
If heavy loading makes handwheel turning difficult,
a 19mm wrench can be used to turn hexagonal
shaft (Figure 18).
For outboard turning, where headstock is moved to
opposite end of lathe to accommodate large bowl
blanks, you can (1) mount the 20-inch bed
extension to the lower set of holes on the Lathe
frame, and (2) mount an extension post [included
with kit] to the tool rest base. See Figure 19.
For larger outboard work, an outboard turning
stand (# 6294732) is available; see section 13.0,
Optional Accessories.

pieces and insert screws only after the shelf has
been established beneath the Lathe.
Shelf Style 1 (Figure 20)
Lay two 2x6 boards flat upon the inner ledges.
Shelf Style 2 (Figure 21)
Lay two 2x6’s (or 2x4’s) on edge into the outer
ledges.
Cut two pieces from a plywood board, and screw
them to the top edges of the 2x6’s. Make the
plywood pieces flush with the outside edge of the
2x6’s. A more refined appearance is achieved by
cutting a rabbet on the inside edge of the 2x6 and
recessing the plywood (as shown).
Figure 19
7.10.3 63-inch Bed Extension
Tools required:
10mm hex key
Dead blow mallet (or hammer with wood block)
The optional 63-inch bed extension with leg
assembly is mounted to the upper set of holes in
similar fashion to the 20-inch bed extension. Install
leg first, level with leveling feet, then attach to
lathe.
7.11 User-made shelf assembly
The double ledges inside the lathe legs provide
support for a shelf (not provided), which is
convenient for storing larger items while keeping
them easily accessible.
Figures 20/21/22 illustrate three methods of
creating a shelf, using common lumber and basic
tools.
IMPORTANT TIP: It is unlikely that a full-size shelf
can be completely built and then inserted between
the Lathe legs. Therefore, construct the shelf in
Figure 20
Figure 21
Shelf Style 3: (Figure 22)
This is a basket-style shelf consisting of two 2x6’s
and dowel rods. The advantage of this design is
that most wood chips will fall through the shelf
instead of accumulating on it. The instructions
below are for building the shelf shown in Figure 22.
