HD-101R Pro24-JCS SAFETY
Consult the owner’s manual for recommended accessories. Using improper accessories
may increase the risk of personal or by-stander injury. Unauthorized equipment
modifications will void all warranties. Manufacturer does not assume responsibility for any
accident due to equipment modifications.
ALWAYS ensure that the machine is on level ground before using.
Serious injury could occur if a power tool is tipped, or if a cutting tool is unintentionally
contacted.
When loading or unloading the machine, use caution. Remove the blade prior to hoisting,
loading and transporting the machine.
USE RECOMMENDED ACCESSORIES
NEVER STAND ON THE TOOL
TRANSPORT
Form a habit of checking to see that keys and adjusting wrenches are removed from
the power tool before it is turned on.
Cluttered work areas and benches invite accidents. Keep area around machine clear of
obstructions which could cause persons to fall.
DO NOT operate equipment in dangerous or hazardous environments. DO NOT use power
tools in damp or wet locations nor expose them to rain. Always keep the work area well
lighted.
REMOVE ADJUSTING KEYS AND WRENCHES
KEEP WORK AREA CLEAN
DO NOT USE IN DANGEROUS PLACES
MAINTAIN TOOLS WITH CARE
Keep tools clean and maintained for the best and safest performance. Always follow
maintenance instructions and examine the machine before use. If any abnormal vibrations
or noises occurs, turn off machine immediately and have the problem corrected before
further use.
DISCONNECT TOOLS
Power tools should always be disconnected before servicing, adjusting or when changing
accessories, such as blades, bits, cutters, and the like.
DO NOT OVERREACH

HD-101R Pro24-JCS SAFETY
Before using a power tool, check for damaged parts. A guard or any other part that is
damaged should be carefully checked to determine if it would operate properly and
perform its intended function. Always check moving parts for proper alignment or binding.
Check for broken parts and mountings and all other conditions that may affect the
operation of the power tool. A guard, or any damaged part, should be properly repaired or
replaced. Always check the machine for loose bolts before starting.
A blade or cutter should always be installed so that rotation is in the direction of the
arrow imprinted on the side of the blade or cutter. It should correspond with the rotational
direction of the motor. Always feed work into a blade against the direction of rotation.
TURN POWER OFF - Do not leave a tool until it comes to a complete stop. ALWAYS
turn a power tool OFF when leaving the work area, or, when a cut is finished.
NEVER LEAVE A TOOL UNATTENDED
CHECK FOR DAMAGED PARTS
DIRECTION OF ROTATION
NEVER disconnect any "emergency or safety devices". These devices are intended for
operator safety. Disconnection of these devices can cause severe injury, bodily harm, or
even death! Disconnection of any of these devices will void all warranties. Unauthorized
equipment modifications will void all warranties. Manufacturer does not assume
responsibility for any accident due to equipment modifications.
NEVER operate this equipment under the influence of drugs or alcohol.
NEVER operate this equipment when not feeling well due to fatigue, illness or taking medicine.
NEVER use this machine with any cutter designed for woodworking.

On belt driven equipment, overtensioning of belts will result in premature crank and/or bearing
failure.
Whenever necessary, replace nameplate, operation and safety decals when they become
difcult to read.
ALWAYS store equipment properly when it is not being used. Equipment should be stored in
a clean, dry location out of the reach of children
DO NOT lend or rent this equipment without including the Owner's Manual and the Engine/
Motor Manufacturer's Manual.
Check the chemical properties of the material to be cut/grinded and follow all EPA/OSHA
Regulations.

HD-101R Pro24-JCS SAFETY
Sawing, grinding and drilling generate dust. Excessive airborne particles may cause irritation to eyes,
skin and respiratory tract. To avoid breathing impairment, always employ dust controls and protection
suitable to the material being sawed or drilled; See OSHA (29 CFR Part 1910.1200).
WARNING
CALIFORNIA PROPOSITION 65 MESSAGE
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities con-
tain chemicals known (to the State of California) to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:
•Lead, from lead-based paints
•Crystalline silica from bricks, cement and other masonry products
•Arsenic and chromium, from chemically treated lumber
For further information, consult the following sources:
http://www.osha.gov/dsg/topics/silicacrystalline/index.html
http://www.cdc.gov/niosh/docs/96-112/
http://oehha.ca.gov/prop65/law/P65law72003.html
http://www.dir.ca.gov/Title8/sub4.html
Your risk from these exposures varies depending on how often you do this type of work. To reduce
your exposure to these chemicals, work in a well-ventilated area, and work with approved safety
equipment, such as dust masks that are specially designed to lter out microscopic particles. Where
use of a dust extraction device is possible, it should be used. To achieve a high level of dust collec-
tion, use an industrial HEPA vacuum cleaner. Observe OSHA 29 CFR part 1926.57 and 1926.103.
SILICA DUST WARNING
Grinding/cutting/drilling of masonry, concrete, metal and other materials with silica in their composition
may give off dust or mists containing crystalline silica. Silica is a basic component of sand, quartz,
brick clay, granite and numerous other minerals and rocks. Repeated and/or substantial inhalation of
airborne crystalline silica can cause serious or fatal respiratory diseases, including silicosis. In ad-
dition, California and some other authorities have listed respirable crystalline silica as a substance
known to cause cancer. When cutting such materials, always follow respiratory precautions.
Use appropriate NIOSH-approved respiratory protection where dust hazard may occur. Paper masks
or surgical masks without a NIOSH approval number are not recommended because they do little to
protect the worker. For more information about respirator programs, including what respirators have
received NIOSH approval as safe and effective, please visit the NIOSH website at:
http://www.cdc.gov/niosh/topics/respirators
Observe OSHA regulations for respirator use (29 C.F.R.§1910.134).
