7. Store tools properly in a safe and dry location to prevent rust or damage.

8. Always lock up tools and keep them out of the reach of children.

PERSONAL SAFETY

CAUTION! Wear protective equipment approved by the Canadian Standards Association (CSA) or American

National Standards Institute (ANSI) when using the tool.

1. Dress properly, wear protective equipment. Use breathing, ear, eye, face, foot, hand, and head protection.

Always wear ANSI approved impact safety goggles, which must provide both frontal and side protection.

Wear a full face shield if your work creates metal ﬁlings or wood chips. Protect your head from falling

objects by wearing a hard hat. Wear an ANSI approved dust mask or respirator when working around

metal, wood and chemical dusts and mists. Wear ANSI approved earplugs. Protective, electrically non-

conductive clothes and non-skid footwear are recommended when working. Wear steel-toed boots to

prevent injury from falling objects.

2. Control the tool, the work piece, personal movement and the work environment to avoid personal injury or

damage to the tool. Stay alert, watch what you are doing and use your common sense.

3. Keep articles of clothing, jewellery, hair, etc., away from moving parts to avoid entanglement with tool.

4. Do not operate any machine / tool when tired or under the inﬂuence of drugs, alcohol or medications.

5. Do not overreach when operating a tool. Proper footing and balance enables better control of a tool in

unexpected situations.

6. Use clamps or other practical ways to support or secure the work piece to a stable platform. Holding the

work piece by hand or against your body is not stable and may lead to loss of control and injury.

Speciﬁc Safety Precautions

1. Keep hands away from cutting area and the blade. If both hands are holding the tool, the blade cannot

cut them.

2. Always wear approved eye protection during use.

3. Do not wear loose clothing or jewelry that could be caught in the moving parts.

4. Do not remove or modify any of the safety features of the tool.

5. Never stand on the tool. Serious injury could occur if the tool is tipped or if the blade is accidentally

touched. To avoid having to stand or lean over the tool, do not store materials above or near it.

6. Always handle the cutter with care when mounting or removing it.

7. Do not start the tool when the blade is touching the work piece.

V 3.05 8507667

Mini Milling Machine

8. Do not touch the cutter or the surface that has been cut with this tool immediately after use. The surface

will be hot and may cause an injury.

9. The unit is heavy. Have the help of an assistant and a lifting tool when moving the unit.

10. In the event of a power failure, turn off the machine as soon as the power is interrupted. The possibility of

accidental injury could occur if the power returns and the unit is not switched off.

11. Do not force the tool. Do not use excessive pressure to operate the tool. A larger, more industrial tool may

be required to perform the required task.

ELECTRICAL SAFETY

1. Disconnect power supply. Disconnect the tool from the power supply when not in use, before cleaning,

servicing or changing any parts.

2. Protect yourself against electric shocks when working on electrical equipment. Avoid body contact with

grounded surfaces such as pipes, radiators, cooking stoves and refrigerators. There is an increased

chance of electrical shock if your body is grounded.

3. Double insulated tools are equipped with a polarized plug (one blade is wider than the other.) This plug will

ﬁt in a polarized outlet only one way. If the plug does not ﬁt fully in the outlet, reverse the plug. If it still

does not ﬁt, contact a qualiﬁed electrician to install a polarized outlet. Do not change the plug in any way.

Double insulation eliminates the need for a three wire grounded power cord and grounded power

supply system.

4. Grounded tools must be plugged into an outlet that is properly installed and grounded in accordance with

all codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use

any adapter plugs. Check with a qualiﬁed electrician if you are in doubt as to whether the outlet is properly

grounded. If the tool should electronically malfunction or break down, grounding provides a low resistance

path to carry electricity away from the user.

5. Do not abuse the cord. Never use the cord to pull the plug from an outlet. Keep the cord away from heat,

oil, sharp edges or moving parts. Do not operate this tool if the power cord is frayed or damaged. Replace

damaged cords immediately. Damaged cords increase the risk of electric shock. Do not modify the plug in

any way.

6. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords

are rated for outdoor use and reduce the risk of electric shock. Use in conjunction with a Ground Fault

Circuit Interrupter (GFCI). If operating a power tool in a damp location is unavoidable, the use of a GFCI

reduces the risk of electric shock. It is recommended that the GFCI should have a rated residual current of

30 mA or less.

7. Avoid using an unnecessarily long extension cord. Choose a cord that is appropriate for the situation, as a

cord that is too long and running across the ﬂoor can be more dangerous than helpful. Using a cord that is

too long or too thin could damage the tool. Unroll the cord completely to prevent it from overheating.

8. Place the electrical cord in a position that prevents it from coming into contact with the tool and from

getting caught by the work piece. The cord should always stay behind the tool.

9. Keep all connections dry and off the ground to reduce the risk of electric shock. Do not touch the plug with

wet hands.

WARNING! People with pacemakers should consult their physician(s) before using this product.

Operations of electrical equipment in close proximity to a heart pacemaker could cause interference or failure

of the pacemaker.

VIBRATION PRECAUTIONS

This tool / work piece vibrates during use. Repeated or long-term exposure to vibration may cause temporary or

permanent physical injury, particularly to the hands, arms and shoulders.

1. Anyone using vibrating tools regularly or for an extended period should ﬁrst be examined by a doctor and

then have regular medical check-ups to ensure medical problems are not being caused by or worsened

from vibrations. Pregnant women or people who have impaired blood circulation to the hands, past hand

injuries, nervous system disorders, diabetes or Raynaud’s Disease should not use tool’s that vibrate. If you

feel any medical symptoms related to vibrations (such as tingling, numbness, and white or blue ﬁngers),

seek medical attention as soon as possible.

2. Do not smoke during use. Nicotine reduces the blood ﬂow to the hands and ﬁngers, increasing the risk of

vibration-related injury.

3. Use tools with the lowest amount of vibration when there is a choice between different processes.

4. Do not use for extended periods. Take frequent breaks when using vibrating tools.

5. Let the tool do the work. Grip the tool as lightly as possible (while still keeping safe control of it).

6. To reduce vibrations, maintain the tool as explained in this manual. If abnormal vibrations occur, stop

using this tool immediately.

INTRODUCTION

You can use the mini milling machine as a drill press or as

a milling machine. A drill chuck is included for the former

function and optional collets and fluted end mills (both

sold separately) are needed for the latter.

Fluted end mills are not designed for use with the drill

chuck. The chuck is not large enough to hold all the mill

end sizes. Nor is the chuck designed to withstand the side

pressure of the milling process. Attempting to use the

fluted end mills with the chuck may result in damage to the

machine and poor mill work.

Princess Auto has Imperial and Metric Collets and Fluted End

Mill sets available. The sale of individual collets are planned.

• Powerfist 8 pc SAE Fluted End Mills (8512188)

• 8 pc SAE Fluted End Mill Collet Set (8640633)

• Powerfist 7 pc Metric Fluted End Mills (8512170)

• 7 pc Metric Fluted End Mill Collet Set (8640625)

INSTALLATION

WARNING! Remove the unit from its power source before

changing any accessories.

CAUTION! Use heavy duty gloves or an oiled cloth when

handling the fluted end mill (I) to avoid damage to the

hands or mill end’s edges.

1. Remove the arbor (G) and drill chuck (see Mini

Milling Machine manual).

2. Remove the protective cover (A).

3. Clean the collet (H).

4. Insert the fixing pin (D) through the spindle box

(#49) into the spindle. Rotate the spindle by hand

until the spindle locks.

5. Use a #14 open end wrench (C) to loosen the draw

bar, but not enough to remove it.

6. Select the fluted end mill (I) and collet (H) that are

matched in diameter.

7. Insert the fluted end mill into the

collet until it is seated. Do not

allow the flutes to enter the collet

as side pressure during cutting

can damage both the end mill

and collet.

8. Screw the collet directly into the

draw bar (B) until hand-tight.

9. Tighten the nut on the draw bar with a wrench.

10. Remove the fixing pin.

11. Reinstall the protective cover.

REMOVAL

1. Follow Steps 1 and 3 for Installation.

2. Use a #14 open end wrench (C) to loosen the draw

bar, but not enough to remove it

3. Unscrew the collet and mill end from the draw bar.

4. Remove the fluted end mill from the collet and wipe

clean before storing.

5. Check the collet’s threads to ensure no debris is

lodged there. Clean and store it in the plastic case.

6. Reinstall the arbor (G) and drill chuck (see Mini

Milling Machine manual).

7. Remove the fixing pin and reinstall the protective cover.

OPERATION

The fluted mill ends are not designed for plunge cutting.

The mill end creates a horizontal flat bottom channel when

moved across the material’s surface.

Drill a hole of the correct diameter into the material. Then

replace the drill chuck with a matching collet and fluted mill

end. Align the mill end to fit into the drilled hole. Follow the

operation instructions in the mini mill manual.
