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.

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.
ALWAYS mount the 8” bowl, it is de-
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.
Install and tighten the 2” (50.8mm)
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.
