Failure to follow these rules may result in serious personal injury.
1.
For your own safety, read the instruction manual before
operating the machine. Learning the machine's application,
limitations, and specific hazards will greatly minimize the
possibility of accidents and injury.
2.
ALWAYS USE SAFETY GLASSES. Also use face or dust
mask if cutting operation is dusty. Everyday eyeglasses
only have impact resistant lenses, they are NOT safety glasses.
Use certified safety equipment. Eye protection equipment should
comply with ANSI Z87.1 standards. Hearing equipment should
comply with ANSI S3.19 standards.
3.
Wear proper apparel. Do not wear loose clothing, gloves,
neckties, rings, bracelets, or other jewelry which may get caught
in moving parts. Nonslip protective footwear is recommended.
Wear protective hair covering to contain long hair.
4.
Do not use the machine in a dangerous environment.
The use of power tools in damp or wet locations or in rain can
cause shock or electrocution. Keep your work area well-lit to
prevent tripping or placing arms, hands, and fingers in danger.
5.
Do not operate electric tools near flammable liquids or in
gaseous or explosive atmospheres. Motors and switches in
these tools may spark and ignite fumes.
6.
Maintain all tools and machines in peak condition. Keep
tools sharp and clean for best and safest performance. Follow
instructions for lubricating and changing accessories. Poorly
maintained tools and machines can further damage the tool or
machine and/or cause injury.
7.
Check for damaged parts. Before using the machine, check
for any damaged parts. Check for alignment of moving parts,
binding of moving parts, breakage of parts, and any other
conditions that may affect its operation. A guard or any other
part that is damaged should be properly repaired or replaced
with RIDGID
or factory authorized replacement parts. Damaged
®
parts can cause further damage to the machine and/or injury.
8.
Keep the work area clean. Cluttered areas and benches invite
accidents.
9.
Keep children and visitors away. Your shop is a potentially
dangerous environment. Children and visitors can be injured.
10. Reduce the risk of unintentional starting. Make sure that
the switch is in the "OFF" position before plugging in the power
cord. In the event of a power failure, move the switch to the
"OFF" position. An accidental start-up can cause injury. Do not
touch the plug's metal prongs when unplugging or plugging in
the cord.
11. Use the guards. Check to see that all safety devices are in
place, secured, and working correctly to prevent injury.
12. Remove adjusting keys and wrenches before starting
the machine. Tools, scrap pieces, and other debris can be
thrown at high speed, causing injury.
13. Use the right machine. Don't force a machine or an
attachment to do a job for which it was not designed. Damage to
the machine and/or injury may result.

14. Use recommended accessories. The use of accessories and
attachments not recommended by RIDGID
to the machine or injury to the user.
15. Use the proper extension cord. Make sure your extension
cord is in good condition. When using an extension cord, be
sure to use one heavy enough to carry the current your product
will draw. An undersized cord will cause a drop in line voltage,
resulting in loss of power and overheating. See the Extension
Cord Chart for the correct size depending on the cord length
and nameplate ampere rating. If in doubt, use the next heavier
gauge. The smaller the gauge number, the heavier the cord.
16. Secure the workpiece. Use clamps or a vise to hold the
workpiece when practical. Loss of control of a workpiece can
cause injury.
17. Feed the workpiece against the direction of the rotation
of the blade, cutter, or abrasive surface. Feeding it from the
other direction will cause the workpiece to be thrown out at high
speed.
18. Do not force the workpiece on the machine. Damage to
the machine and/or injury may result.
19. Do not overreach. Loss of balance can make you fall into a
working machine, causing injury.
20. Never stand on the machine. Injury could occur if the tool
tips, or if you accidentally contact the cutting tool.
21. Never leave the machine running unattended. Turn the
power off. Don't leave the machine until it comes to a complete
stop. A child or visitor could be injured.
22. Turn the machine "OFF", and disconnect the machine
from the power source before installing or removing
accessories, changing cutters, adjusting or changing set-
ups. When making repairs, be sure to lock the start switch in the
"OFF" position. An accidental start-up can cause injury.
23. Make your workshop childproof with padlocks, master
switches, or by removing starter keys. The accidental start-
up of a machine by a child or visitor could cause injury.
24. Stay alert, watch what you are doing, and use common
sense. Do not use the machine when you are tired or under
the influence of drugs, alcohol, or medication. A moment of
inattention while operating power tools may result in injury.
Use of this tool can generate and disperse dust or
other airborne particles, including wood dust, crystalline silica dust
and asbestos dust. Direct particles away from face and body. Always
operate tool in well ventila ted area and provide for proper dust
removal. Use dust collection system wherever possible. Exposure
to the dust may cause serious and permanent respiratory or other
injury, including silicosis (a serious lung disease), cancer, and death.
Avoid breathing the dust, and avoid prolonged contact with dust.
Allowing dust to get into your mouth or eyes, or lay on your skin may
promote absorption of harmful material. Always use properly fitting
NIOSH/OSHA approved respiratory protection appropriate for the dust
exposure, and wash exposed areas with soap and water.
