SAFETY INSTRUCTIONS
Safety Instructions:
Introduction
Thank you for purchasing your new machine from Husqvar-
na Construction Products. We have provided important
safety messages in this manual and on the machine.
Please read these messages carefully. A safety message
alerts you to potential hazards that could hurt you or others.
Each safety message is preceded by a symbol or the safety
WARNING!
Before starting up machine make sure you
completely read these instructions and the
power cutter operation manual. Be familiar with
operation of the machine before operation!
alert symbol (
CAUTION.
) and one of two words, WARNING, or
Your SpeedMill comes with two Operator’s
Manual’s. This one for the SpeedMill attach-
ment and one for the K750 power head. It is the
owner’s responsibility to ensure that all opera-
tors of this SpeedMill have read and under-
stood the content of both manuals before using
the product.
These signal words mean:
WARNING: Indicates a hazardous situation which, if not
avoided COULD result in death or serious injury.
CAUTION: Indicates a hazardous situation, which, if not
avoided, COULD result in minor or moderate injury. It may
also be used to alert against unsafe practices.
Each message tells you what the hazard is, what can hap-
pen, and what you can do to avoid or reduce injury.
WARNING!
NEVER use a SpeedMill as a standard power cutter. A
SpeedMill is ONLY for USES listed in this document.
NOTICE: Indicates a hazardous situation which, if not
avoided, COULD result in property damage. Your machine
or other property can be damaged if you don’t follow this
instruction.
Cut only PVC plastic pipe with a machine equipped with
a SpeedMill Accessory! DO NOT cut other materials.
Use ONLY High Speed Reinforced Abrasive Blades with
this machine.
If the label is worn, damaged, or is illegible, it should be
replaced.
DO NOT use carbide tipped, wood cutting, or circular
saw blades with this machine.
Contents of Package
DO NOT use diamond or rescue blades with this ma-
chine! Cutting plastics with a diamond or rescue blade
can cause kickback. The heat produced melts the
material and it sticks to the blade.
Verify the contents of the package:
• SpeedMill Power Cutter.
• SpeedMill Bowl Assembly: 100mm (4”), 150mm (6”), and
200mm (8”) Bowls with Hub and 2.00” Nut.
DO NOT cut ductile iron pipe with a SpeedMill.
• Document Package. Operation Manual for Power Cut-
ter, Spare Parts List for Power Cutter, Operation Manual /
Spare Parts List for Speed Mill Accessory (This Document).
DO NOT touch Bowl when machine is running. Speed-
Mill Bowl Rotates with Blade.
Before performing any maintenance, ALWAYS locate
the machine on a level surface with the engine / motor
OFF and the start switch in the OFF position, and the
power source disconnected.
If these items are not included in the package, contact our
customer service department at the telephone number
shown in this document.
EVACUATE PIPE CONTENTS before cutting; else EX-
PLOSION may occur. Static electricity from the cutting
operation may cause sewer or other gas within the pipe
to explode.
The working area must be completely
clear, well lit and all safety hazards
removed.

SAFETY INSTRUCTIONS
WARNING!
Read, understand, and follow all warnings and instructions in this and the K750 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 possible risk situations that
can arise in conjunction with pipe cutting and beveling within these instructions. 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, or 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.
The operator must
wear protective
clothing
appropriate to the
work he is doing.
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 blades with a minimum speed rating of 6300 rpm. Many blades are not made
for hand held high speed saw and they all have a lower speed rating (marked on their label) Such blades might brake
at higher speed 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.

USES, TOOLS, AND ASSEMBLY
Uses: Cutting and beveling of 100mm (4”), 150mm (6”),
and 200mm (8”) PVC pipe of the following types; ASTM
D2241 IPS Gasketed Pipe, and ASTM D3034 Gravity
Sewer Pipe (Type SDR 35, and SDR 26). Note that this
machine, as supplied, is not designed for cutting AWWA
C900 Municipal Water Pipe, or any non-plastic material.
CAUTION!
Always install the 8” SpeedMill Bowl (P/N 542 19 61-
89) before using the machine! The 8” SpeedMill must
always be installed even if the machine will only be
used to cut and bevel smaller diameter pipes. Besides
serving as a beveller for 8” pipes the 8” flange is also
designed to cover the area between the guard and the
flange and to prevent unintentional contact with the
blade.
WARNING!

ASSEMBLY AND OPERATION
OPERATION:
Mount the SpeedMill Bowl
Assembly. Align the slot in the
SpeedMill Hub with the face of
the shaft. Make sure the flange
face of the SpeedMill Hub con-
tacts the face of the blade.
WARNING!
Before starting up machine make sure you
completely read these instructions and the
power cutter operation manual. Be familiar with
operation of the machine before operation!
Install the blade shaft bolt into
the Hub Assembly.
WARNING!
EVACUATE PIPE CONTENTS before cutting; else
EXPLOSION may occur! Static electricity from cut-
ting operation may cause gas or other pipe contents
to explode (for installed piping).
Position plastic pipe so pipe end is
off the ground. Secure pipe in place
if required. Example: Set plastic
pipe between two of the boards of a
wooden pallet.
Using Combination Spanner,
Supplied with machine, tighten
blade shaft bolt by turning it
clockwise. Torque to 130-215
in-lbs. (15-25 Nm).
Before starting machine,
verify that when SpeedMill
Bowl and blade is positioned
to cut / bevel the plastic pipe,
that it clears all objects in the
cutting area.
Before using the assem-
bled machine, completely
read the power cutter op-
eration manual supplied
with this machine.
Start machine per instructions in K750
Power Cutter Operation Manual.
Position machine at top of plas-
tic pipe to begin cutting through
the pipe wall.
Move saw forward while
maintaining a “square cut”
on the end of the pipe. This
means the cut should al-
ways be perpendicular to the
length of the pipe.
8 SpeedMill
OPERATION
Rotate Pipe and repeat this cut-
ting process until pipe circum-
ference is cut.
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 mate-
rial.
Bevel Pipe: Position SpeedMill
Bowl near end of pipe to be
beveled. Accelerate power cut-
ter to full throttle.
WARNING!
HOLD MACHINE ONLY at front and rear handles!
NEVER bevel or cut material while holding the pipe with
your hands!

MAINTENANCE
MAINTENANCE:
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 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.
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 damages and become unusable.
WARNING!
NEVER use the SpeedMill as a regular power cutter!
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.
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.
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).
Cleaning
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 scrap
shavings from bowl using
a screwdriver or any other
hard metallic tool. Damage
to the bowls or abrasive
coating could occur.
