SAFETY INSTRUCTIONS

WARNING!

Read, understand, and follow all warnings and instructions both manuals. Failure to do so may result

in serious personal injury as well as damage to the equipment. It is not possible to cover all potentional risk situations

that can arise from pipe cutting and beveling within these instructions. Therefore use common sense and caution at all

times.

Remember: “If you don’t know – don’t do.”

The SpeedMill may not be modiﬁed from its original design without the manufacturer’s approval in writing. Unapproved

modiﬁcations can result in serious injury.

All operators must be trained in the proper use of this machine. It is the owner’s responsibility to explain the content of

this manual to all operators and ensure that they receive the necessary training to safely operate this machine.

PERSONAL SAFETY

Stay alert, watch what you are doing, and use common sense when operating this SpeedMill or any other

power tool. Do not use when tired or under the inﬂuence of drugs, alcohol, medication, or any substance that could

affect your judgment. A moment of inattention during operation may result in serious personal injury.

Keep proper footing and balance at all times. Do not overreach or operate from a ladder. Do not operate above

chest height. If necessary use proper scaffolding to reach a safe operating height.

Use personal safety equipment. Always wear eye protection, hard hat, hearing protection, non-slip safety shoes and

gloves. Respirator mask must be used when dry-cutting. (Reference OSHA 29CFR 1910.95, 1910.133-138)

Dress properly. Never wear loose clothing or jewelry. Keep long hair tied back. Keep your hair, clothing, and gloves

away from the rotating blade.

Do not use the SpeedMill if the ON/OFF switch does not turn it on or off. Have the switch replaced before the

SpeedMill is used again.

WORK AREA SAFETY

Keep the work area organized. Maintain a ﬁrm grip of the SpeedMill and have a proper footing and balance at all

times.

Do not operate your SpeedMill in an explosive atmosphere. Sparks may ignite ﬂammable liquids,

gases, or dust. This is a concern when old pipes are being repaired.

Keep all bystanders at a safe distance. Bystanders can be a distraction that can cause you to lose control.

CHOICE OF BLADE

Use only 12” high speed abrasive concrete cutting blades for cutting speciﬁed PVC pipe with the SpeedMill.

Use only blades designated High Speed blade with a minimum speed rating of 6300 rpm. Many blades are not made

for hand held high speed saws and have a lower speed rating (marked on label). Such blades might brake at higher

speeds with possible severe injury as a result.

Diamond blades shall not be used while cutting any plastic pipe due to the increased risk of “kick-back”. (Regard-

ing kick-back see K750 operation manual).

Use of carbide tipped blades or any blade with cutting teeth, is a violation of OSHA regulations and shall never be used.

The operator must

wear protective

clothing

appropriate to the

work he is doing.

506 37 96-25) is pushed onto blade

shaft so it contacts the inner flange.

The mounting surfaces of the flange

and bushing arbor must be undam-

aged, clean, and free of debris. Ver-

ASSEMBLY AND OPERATION

8 SpeedMill

Assembling the bevelling bowls to

the SpeedMill.

Bowl Bevelers 506 11 97-01 for:

Waste/Sewer/Drain 4” to 8” in diameter.

Mount the beveling bowl in order 8”

first, 6” second, and 4” last.

signed to shield operator in case the

blade breaks.

Always install the 8” SpeedMill Bowl (P/N 542 19 61-89)

before using the machine! The 8” SpeedMill Bowl must

always be installed even if the machine will only be used

to cut and bevel smaller diameter pipes. Besides serv-

ing as a beveler for 8” pipes, the 8” flange is also de-

signed to cover the area between the guard and the

flange and to prevent unintentional contact with the

blade.

Assembling the bevelling ring to the

SpeedMill.

Ring Beveler 506 11 96-01 for:

Sewer/Drain 10” to 36” in diameter.

Supply/Water 4” to 24” in diameter.

Mount the Ring Beveler assembly

onto the hub shaft.

hub nut with the proper tool. Torque

to 130-215 in-lbs. (15-25 Nm).

NOTE: Do not tighten excessively –

nut will tighten during cutting process

– making disassembly difficult.

When tightening the hub nut, use a

screwdriver to lock the blade shaft in

position. Push the screwdriver into

the slot (see picture) and rotate the

arbor until the screwdriver stops the

rotation.

Before using the assem-

bled machine, completely

read the power cutter op-

eration manual supplied

with this machine.

OPERATION:

CAUTION!

Before starting machine, make sure

you completely read these instructions

and the power cutter operation manual.

Be familiar with the functions of the

machine before operation!

WARNING!

Before starting machine, verify that when SpeedMill Bowl

and blade are positioned to cut / bevel the plastic pipe,

that the cutting area is cleared of all objects.

Position machine at top of plastic pipe

to begin cutting through the pipe wall.

NOTE:

When using the ring beveler, the pipe

is cut and beveled in one operation.

Move saw forward while maintain-

ing a “square cut” on the end of

the pipe. This means the cut

should always be perpendicular to

the length of the pipe.

OPERATION

SpeedMill 9

Position plastic pipe so pipe end is

off the ground. Secure pipe in place

if required. Example: Set plastic

pipe between two boards of a

wooden pallet.

EVACUATE PIPE CONTENTS before cutting or

else an EXPLOSION may occur! Static electricity from

cutting operation may cause gas or other pipe contents

to explode.

Bevel Pipe:

Position SpeedMill Bowl near

end of pipe to be beveled.

Accelerate power cutter to full

throttle.

Align proper SpeedMill Bowl with

end of pipe, and move toward

the pipe so that the pipe is

slightly beveled.

Note: The bevel required is

usually quite small, so do not

remove excessive pipe material.

HOLD MACHINE ONLY

at front and rear handles,

as shown in the photo to

the left.

WARNING!

HOLD MACHINE ONLY at front and rear handles!

NEVER bevel or cut material while holding the pipe with

your hands!

DO NOT use blade guard pivot handle as a hand hold

while operating machine!

Start machine per instructions in K750

Power Cutter Operation Manual.

Rotate pipe and repeat this

cutting process until pipe

circumference is cut.

WARNING!

10 SpeedMill

MAINTENANCE:

CAUTION!

Allow SpeedMill Bowls to cool before performing any main-

tenance.

NOTICE!

DO NOT hold SpeedMill Bowls using a screwdriver or

other device through the slots in the bowl. Damage to

the bowls or abrasive coating could occur.

DO NOT use a screw driver or similar in the slots of the

SpeedMill Bowls to lock the blade. If you do it is likely

the ﬂanges will be damaged and become unusable.

Use the proper procedure to lock the blade when at-

taching or removing the blade or ﬂanges – See below,

or see K750 Operation Manual.

When removing the Hub nut,

use a Screwdriver to lock the

blade shaft in position. Push

the screwdriver into the slot

(see picture) and rotate the ar-

bor until the screwdriver stops

the rotation.

SPARE PARTS:

The parts required for the SpeedMill Accessory are shown

on the next page. For any other parts used on this ma-

chine see the power cutter spare parts list (included).

MAINTENANCE

Plastic debris from a small-

er ﬂange often lodges itself

in the bigger ﬂange during

cutting. This can easily be

removed once the ﬂanges

have cooled down.

Use compressed air to

blow shavings from Speed-

Mill Bowl. DO NOT scrape

shavings from bowl using

a screwdriver or any other

hard metallic tool. Damage

to the bowls or abrasive

coating could occur.

Inspect the SpeedMill Bowls

Always inspect the SpeedMill Bowls before you start cut-

ting. Small nicks or scratches can be sanded smooth. If

the SpeedMill Bowl has been bent or distorted in any way it

must be replaced.

Cleaning

WARNING!

NEVER use the SpeedMill as a regular power cutter!

CONVERTING THE SPEEDMILL TO A REGU-

LAR POWER CUTTER.

The guard on the SpeedMill is designed to work together

with the special outer ﬂange and SpeedMill Bowls used

on the SpeedMill. The 8” (200mm) SpeedMill Bowl must

always be installed when the SpeedMill is used and the

SpeedMill shall not be used for any other purpose than

those mentioned in “USES” section (p7) of this document.

Should you desire to convert the SpeedMill to a regular

power cutter you must replace the cutting head with an

original 12” or 14” cutting head attachment. We recom-

mend you have an authorized dealer do the conversion.
