SECTION 1: SAFETY

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 which are intended to convey the level of

importance 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.

Indicates an imminently hazardous situation which, if not avoided,

WILL result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided,

COULD result in death or serious injury.

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.

This symbol is used to alert the user to useful information about

proper operation of the machine.

Clean Up

Site Considerations

The unpainted surfaces are coated with a waxy

oil to protect them from corrosion during ship-

ment. Remove this protective coating with a sol-

vent cleaner or citrus-based degreaser such as

Grizzly’s G7895 Degreaser. To clean thoroughly,

some parts may need to be removed. For opti-

mum performance from your machine, make

sure you clean all moving parts or sliding

contact surfaces that are coated. Avoid chlo-

rine-based solvents, such as acetone or brake

parts cleaner, as they may damage painted sur-

faces should they come in contact. Always follow

the manufacturer’s instructions when using any

type of cleaning product.

Floor Load

Refer to the Machine Data Sheet for the weight

and footprint specifications of your machine.

Some residential floors may require additional

reinforcement to support both the machine and

operator.

Working Clearances

Consider existing and anticipated needs, size of

material to be processed through each machine,

and space for auxiliary stands, work tables or

other machinery when establishing a location for

your new machine. See Figure 4 for the minimum

working clearances.

Gasoline and petroleum

products have low flash

points and could cause

an explosion or fire if

used to clean machinery.

DO NOT use gasoline or

petroleum products to

clean the machinery.

��

�

��

�

Many of the solvents

commonly used to clean

machinery can be toxic

when inhaled or ingest-

ed. Lack of ventilation

while using these sol-

vents could cause seri-

ous personal health risks

or fire. Take precautions

from this hazard by only

using cleaning solvents

in a well ventilated area.

Figure 4. Minimum working clearances.

Unsupervised children and

visitors inside your shop

could cause serious per-

sonal injury to themselves.

Lock all entrances to the

shop when you are away and

DO NOT allow unsupervised

children or visitors in your

shop at any time!

To mount the lathe bed:

Mounting Lathe

1. Move the stand to where you plan to locate

the lathe.

2. Using a forklift, lift the lathe bed onto the

stand by placing the lifting straps through

the center of the bed and around the cast-

ing webs, as shown in Figure 5. The strap

closest to the headstock should be wrapped

around the forklift forks a few times to com-

pensate for the heavier weight load on that

side.

The Model G0456 is

an extremely heavy

machine. Serious per-

sonal injury may occur

if safe moving methods

are not followed. To be

safe, use assistance and

power equipment when

moving the machine. If

you are unfamiliar with

safe machine lifting prac-

tices, hire professionals.

The lathe bed and stand are separated for ship-

ping safety purposes. We recommend positioning

the stand in the final location for the lathe before

mounting the lathe bed. L-brackets are also pro-

vided for floor mounting.

When lifting the lathe, use a forklift and lifting

straps—and have another person on the ground

to steady the lathe while moving, so the lathe

doesn't swing uncontrollably.

Dust Collection

Test Run

Once the assembly is complete, test run the lathe

to make sure it runs properly.

DO NOT operate the Model G0456 disc sand-

er without an adequate dust collection sys-

tem. Sanding creates substantial amounts

of fine dust. Failure to use a dust collection

system can result in short- and long-term

respiratory illness.

If, during the test run, you cannot easily locate

the source of an unusual noise or vibration, stop

using the machine immediately, then review the

Troubleshooting on Page 30.

If you still cannot remedy a problem, contact our

Tech Support at (570) 546-9663 for assistance.

Recommended CFM at Dust Port: 100 CFM

Do not confuse this CFM recommendation with

the rating of the dust collector. To determine the

CFM at the dust port, you must take into account

many variables, including the CFM rating of the

dust collector, the length of hose between the

dust collector and the machine, the amount of

branches or wyes, and the amount of other open

lines throughout the system. Explaining this cal-

culation is beyond the scope of this manual. If

you are unsure of your system, consult an expert

or purchase a good dust collection "how-to" book.

Refer to Grizzly Model G2525 "Dust Collection

Basics."

To test run the machine:

1. Plug the lathe into the power source.

2. Turn the speed dial to OFF, then lift the

paddle switch up to turn the lathe ON.

3. Turn the speed dial to start the lathe spindle

motor. The spindle should rotate.

4. Listen to and watch for abnormal noises or

actions. The lathe should run smoothly with

little or no vibration or rubbing noises.

To connect a dust collection hose:

—Strange or unusual noises should be

investigated and corrected before operat-

ing the machine further. Always unplug the

machine when investigating or correcting

the machine.

1. Fit the 2" dust hose or adapter over the dust

port, as shown in Figure 9, and secure in

place with a hose clamp.

2. Tug the hose to make sure it does not come

off. Note: A tight fit is necessary for proper

performance.

5. Test the variable speed by slowly turning the

speed up, then down, once.

—The machine should have sped up and

slowed down as you moved the dial. If

it did, then the test run is over and your

machine is ready for normal operations.

—If the lathe had problems changing speeds,

refer to the Troubleshooting chart on

Page 30, or call our Tech Support at (570)

546-9663 for additional help.

Scrapers: Mainly used where access for

other tools is limited, such as hollowing oper-

ations. This is a flat, double-ground tool that

comes in a variety of profiles (Round Nose,

Spear Point, Square Nose, etc.) to match

many different contours. Figure 20 shows an

example of a round nose scraper.

Selecting Turning

Tools

Lathe tools come in a variety of shapes and sizes

and usually fall into five major categories.

•

Gouges: Mainly used for rough cutting, detail

cutting, and cove profiles. The rough gouge

is a hollow, double-ground tool with a round

nose, and the detail gouge is a hollow, dou-

ble-ground tool with either a round or pointed

nose. Figure 18 shows an example of a

gouge.

Figure 20. Round nose scraper.

•

Parting Tools: Used for sizing and cutting off

work. This is a flat tool with a sharp pointed

nose that may be single- or double-ground.

Figure 21 shows an example of a parting

tool.

Figure 18. Gouge.

•

Skew Chisel: A very versatile tool that can be

used for planing, squaring, V-cutting, bead-

ing, and parting off. The skew chisel is flat,

double-ground with one side higher than the

other (usually at an angle of 20-40˚). Figure

19 shows an example of a skew chisel.

Figure 21. Parting tool.

•

Specialty Tools: These are the unique, spe-

cial function tools to aid in hollowing, bowl

making, cutting profiles, etc. The Swan Neck

Hollowing Tool shown on Page 27 is a good

example of a specialty tool.

2. Using a wood mallet, tap the point of the spur

center into the center of the workpiece, so it

leaves a center mark, then remove the spur

center.

Spindle Turning

Spindle turning (Figure 22) is the operation per-

formed when a workpiece is mounted between

the headstock and the tailstock.

3. Using a ¹⁄4" drill bit, drill a ¹⁄4" deep hole at the

center mark. (Additionally, if the end of your

workpiece is square, cut ⁄8" deep saw kerfs

across the corners to help embed the spur

center.)

4. Cut the corners off your workpiece if it is over

2" x 2" to make turning safer and easier.

5. Drive the spur center into the center of the

workpiece with a wood mallet to embed it at

least ¹⁄4", as shown in Figure 24.

Figure 22. Typical spindle turning operation.

To set up a spindle turning operation:

��

1. Mark both ends of your workpiece by draw-

ing diagonal lines from corner to corner. The

intersection point of these lines will show you

the center of your workpiece. See Figure 23

for details.

Figure 24. Spur center properly embedded.

��

6. With the workpiece still attached, insert the

spur center into the headstock spindle.

��

7. With the live center installed in the tailstock,

slide the tailstock toward the workpiece until

the live center touches the workpiece center-

point, then lock the tailstock in this position.

8. Use the tailstock adjustment knob to push the

live center into the workpiece at least a ¹⁄4".

��

Figure 23. Workpiece marked diagonally from

corner-to-corner to determine the center.

Do not press the workpiece too firmly with

the tailstock or the bearings will bind and

overheat. Likewise, do not adjust too loose-

ly or the workpiece will spin off the lathe.

Use good judgement. Serious personal

injury could result if care is not taken.

10. Test the setup by hand-turning the workpiece

to make sure there is enough clearance all

the way around before starting.

To mount your workpiece to the faceplate:

1. Find the center of your workpiece in the same

manner as when spindle turning.

•

When turning the lathe ON, stand to the side

of the spinning direction until the lathe reach-

es full speed and you can verify that the lathe

will not throw the workpiece.

2. Optional: Trim corners off the workpiece with

a bandsaw to easily remove known waste.

3. Center the faceplate on the workpiece and

attach it through the faceplate holes with

wood screws, as shown in Figure 27.

•

Use the slowest speed when starting or stop-

ping the lathe, and when rough cutting.

Select the right speed for the size of workpiece

you are turning. Use slower speeds for

large workpieces (4" diameter and over); use

the middle range speeds for medium sized

workpieces (2" to 4" diameter); and use faster

speeds for small sized workpieces (under 2"

in diameter).

•

Keep the turning tool on the tool rest the

ENTIRE time that it is in contact with the

workpiece.

Learn the correct techniques for each tool

you will use. If you are unsure, read books or

magazines about lathe techniques and seek

training from experienced users.

To mount your workpiece to a backing block:

7. Replace the front and rear covers.

1. Make the backing block from a piece of scrap

wood that is flat on both sides.

Sanding/Finishing

2. Locate and mark the center of both the

workpiece and the backing block.

After turning, the workpiece can be sanded, as

shown in Figure 29, and finished (in the same

manner) before removing it from the lathe.

3. Drill a ⁄4" hole in the center of the backing

block.

4. Glue the center of the backing block to the

center of the workpiece (look through the

drilled hole to line up centers), clamp the

backing block to the workpiece, and wait for

the glue to cure according to the manufactur-

er’s recommendation.

Attaching Sandpaper

Disc Sanding

To perform sanding operations:

The disc sander accepts 12" diameter cloth or

paper-backed PSA sanding discs, which are

available through Grizzly (see Page 28).

1. Set the angle of the table relative to the sand-

ing disc. The angle can be set with the angle

gauge on the disc sander or with a protractor

for greater accuracy.

The sanding disc sticks to the surface of the cast

iron disc, using the pressure sensitive adhesive

backing (PSA) on the reverse side of the sandpa-

per disc. The sandpaper can be replaced without

removing either the table or the dust port.

2. When a 90˚ horizontal angle is required,

place one surface of the workpiece firmly

against the face of the miter gauge (set at

0˚), with the other surface against the face of

the disc (Figure 31).

To attach sandpaper:

1. Peel back the protective layer on one-half

of the sandpaper disc and fold it against the

remaining half.

Note: For sanding curves or irregular shapes,

remove the miter gauge from the disc table.

Always keep the workpiece on the side of the

wheel that is rotating down toward the table. This

will keep the workpiece from flying out of your

hands from the rotational forces.

2. Slip the half with the protective layer between

the disc and the table edge.

3. Position the exposed adhesive on the upper

half of the disc that extends above the table.

Once it is positioned evenly across the disc,

press the adhesive onto the surface.

4. Now rotate the disc so the lower half is now

above the table.

5. Bend the paper back and remove the remain-

ing half of the protective layer (Figure 30),

then press the adhesive portion against the

disc.

Miter Sanding

Angle Sanding

The most efficient way to get a perfect miter is to

cut the workpiece slightly long and sand it to the

desired dimension. Use the miter gauge to hold

the workpiece at the desired angle.

To perform angle sanding operations:

1. Loosen the handles securing the table.

2. Use the angle gauge to achieve the desired

table angle and tighten the handles.

To perform miter sanding operations:

1. Loosen the knob on the miter gauge and

adjust the angle to the desired point. Tighten

the knob.

Note: The disc table can be positioned from

-15˚ to 35˚, relative to the plane of the sand-

ing surface. Whenever possible, sand with

an open angle where there is plenty of clear-

ance between the disc and the table. This

will avoid trapping the workpiece between

the sanding surface and the table.

2. Slide the miter gauge into its slot and use it

to hold your workpiece in position.

Note: The miter gauge can be used in either

direction in the slot to achieve the proper

relation of the workpiece to the disc.

3. Slide the miter gauge into its slot and use it

to hold your workpiece in position.

3. With light, but steady pressure, push the

workpiece slowly into the downspin side of

the rotating disc (Figure 32).

4. With light, but steady pressure, push the

workpiece slowly into the downspin side of

the rotating disc (Figure 33).

Brushes

9. Remove the motor mount bolts and the motor

from the headstock.

The Model G0456 features a DC motor, which

uses heavy-duty carbon brushes. While these

brushes are designed for extended life, they will

eventually wear out, causing a loss of power or

faulty starting. This procedure takes approxi-

mately 45 minutes to complete and requires you

to remove and discard the sandpaper disc if it is

installed. If you need help locating any parts of

the machine, refer to the parts breakdown.
