CAUTION.
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 happen, and what you can do to avoid or reduce injury.
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.
If the label is worn, damaged, or is illegible, it should be
replaced.

Safety Instructions:
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!
Your SpeedMill comes with two Operator’s
Manual’s. This one for the SpeedMill attachment and one for the K750 power head. It is the
owner’s responsibility to ensure that all operators of this SpeedMill have read and understood the content of both manuals before using
the product.
WARNING!
NEVER use a SpeedMill as a standard power cutter. A
SpeedMill is ONLY for USES listed in this document.
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.
DO NOT use carbide tipped, wood cutting, or circular
saw blades with this machine.
DO NOT use diamond or rescue blades with this machine! Cutting plastics with a diamond or rescue blade
can cause kickback. The heat produced melts the
material and it sticks to the blade.
DO NOT cut ductile iron pipe with a SpeedMill.
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.
EVACUATE PIPE CONTENTS before cutting; else EXPLOSION 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.
Any persons not involved in the work,
should leave the area.
Stop, in the fixed position.
Other symbols/decals on the machine refer to special
certification requirements for certain markets.
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 modied from its original design without the manufacturer’s approval in writing. Unapproved
modications 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 inuence 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 rm grip of the SpeedMill and have a proper footing and balance at all
times.
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 specied 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”. (Regarding 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.
Do not operate your SpeedMill in an explosive atmosphere. Sparks may ignite ammable liquids,
gases, or dust. This is a concern when old pipes are being repaired.

MAINTENANCE
MAINTENANCE:
CAUTION!
Allow SpeedMill Bowls to cool before performing any maintenance.
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 anges will be damages and become unusable.
Use the proper procedure to lock the blade when attaching or removing the blade or anges – 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 arbor until the screwdriver stops
the rotation.
CONVERTING THE SPEEDMILL TO A REGULAR POWER CUTTER.
The guard on the SpeedMill is designed to work together
with the special outer ange 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 recommend you have an authorized dealer do the conversion.
WARNING!
NEVER use the SpeedMill as a regular power cutter!
Inspect the SpeedMill Bowls
Always inspect the SpeedMill Bowls before you start cutting. 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
Plastic debris from a small-
10 SpeedMill
er ange often lodges itself
in the bigger ange during
cutting. This can easily be
removed once the anges
have cooled down.
Use compressed air to
blow shavings from SpeedMill 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.
