Warning
1. Read and understand this entire manual before attempting assembly or operation.
2. Read and understand the warnings posted on the machine and in this manual. Failure to comply with
all of these warnings may cause serious injury.
3. Replace the warning labels if they become obscured or removed.
4. This sander is designed and intended for use by properly trained and experienced personnel only. If
you are not familiar with the proper and safe operation of a sander, do not use until proper training
and knowledge have been obtained.
5. Do not use this sander for other than its intended use. If used for other purposes, WMH Tool Group
disclaims any real or implied warranty and holds itself harmless from any injury that may result from
that use.
6. Always wear approved safety glasses/face shields while using this sander. Everyday eyeglasses only
have impact resistant lenses; they are not safety glasses.
7. Before operating this sander, remove tie, rings, watches and other jewelry, and roll sleeves up past
the elbows. Remove all loose clothing and confine long hair. Non-slip footwear or anti-skid floor strips
are recommended. Do not wear gloves.
8. Wear ear protectors (plugs or muffs) during extended periods of operation.
9. Some dust created by power sanding, sawing, grinding, drilling and other construction activities
contain chemicals known to cause cancer, birth defects or other reproductive harm. Some examples
of these chemicals are:
• Lead from lead based paint.
• Crystalline silica from bricks, cement and other masonry products.
• Arsenic and chromium from chemically treated lumber.
Your risk of exposure 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 face or dust masks that are specifically designed to filter out microscopic
particles.
10. Do not operate this machine while tired or under the influence of drugs, alcohol or any medication.
11. Make certain the switch is in the OFF position before connecting the machine to the power supply.
12. Make certain the machine is properly grounded.
13. Make all machine adjustments or maintenance with the machine unplugged from the power source.
14. Remove adjusting keys and wrenches. Form a habit of checking to see that keys and adjusting
wrenches are removed from the machine before turning it on.
15. Keep safety guards in place at all times when the machine is in use. If removed for maintenance
purposes, use extreme caution and replace the guards immediately.
16. Make sure the sander is firmly secured to the stand or work table before use.
17. Check damaged parts. Before further use of the machine, a guard or other part that is damaged
should be carefully checked to determine that it will operate properly and perform its intended
function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting
and any other conditions that may affect its operation. A guard or other part that is damaged should
be properly repaired or replaced.
18. Provide for adequate space surrounding work area and non-glare, overhead lighting.
19. Keep the floor around the machine clean and free of scrap material, oil and grease.
20. Keep visitors a safe distance from the work area. Keep children away.

blahblahblah
21. Make your workshop child proof with padlocks, master switches or by removing starter keys.
22. Give your work undivided attention. Looking around, carrying on a conversation and “horse-play” are
careless acts that can result in serious injury.
23. Maintain a balanced stance at all times so that you do not fall or lean against moving parts. Do not
overreach or use excessive force to perform any machine operation.
24. Stand to one side of the conveyor and make sure no one else is standing in line with the conveyor
while feeding into the machine. Should a part slip while being fed, it may exit the machine at a high
rate of speed and can cause injuries to anyone standing directly in front of the infeed.
25. Use the right tool at the correct speed and feed rate. Do not force a tool or attachment to do a job for
which it was not designed. The right tool will do the job better and safer.
26. Use recommended accessories; improper accessories may be hazardous.
27. Maintain tools with care. Keep abrasives clean for the best and safest performance. Follow
instructions for lubricating the machine and changing accessories.
28. Always feed stock against the rotation of the drum.
29. Keep your hands clear when feeding parts onto the conveyor. The part will be forced down as it
begins to feed, causing a pinching action between the part and the conveyor bed. Never reach into a
running machine. Turn off sander and disconnect from power before attempting to retrieve parts from
beneath the drum.
30. Turn off the machine and disconnect from power before cleaning. Use a brush or compressed air to
remove chips or debris — do not use your hands.
31. Do not stand on the machine. Serious injury could occur if the machine tips over.
32. Never leave the machine running unattended. Turn the power off and do not leave the machine until it
comes to a complete stop.
33. Remove loose items and unnecessary work pieces from the area before starting the machine.
Familiarize yourself with the following safety notices used in this manual:
This means that if precautions are not heeded, it may result in minor injury and/or
possible machine damage.
This means that if precautions are not heeded, it may result in serious injury or possibly
even death.
