recommended by the power tool manufacturer.
7.2.2.9 WORKPLACE HAZARDS
• Slips, trips and falls are major causes of workplace injury. Be aware
of slippery surfaces caused by use of the tool and also of trip hazards
caused by the air line or hydraulic hose.
• Proceed with care in unfamiliar surroundings. Hidden hazards may
exist, such as electricity or other utility lines.
• This power tool is not intended for use in potentially explosive atmo-
spheres and is not insulated from coming into contact with electric
power.
• Make sure there are no electrical cables, gas pipes etc. that could
cause a hazard if damaged by use of the tool.
7.2.2.10 DUST AND FUME HAZARDS
• Dust from some work processes can cause cancer, birth defects or
other respiratory diseases. Risk assessment of these hazards and
implementation of appropriate controls is essential.
• If the pneumatic tool is used in a dust lled environment exhaust
air can cause a dust hazard
• Dusts and fumes generated when using power tools can cause
ill health (for example: cancer, birth defects, asthma and/or der-
matitis); risk assessment of these hazards and implementation of
appropriate controls of is essential.
• Risk assessment should include dust created by the use of the tool
and the potential for disturbing existing dust.
• Operate and maintain the power tool as recommended in these
instructions, to minimize dust or fume emissions

suppression of airborne dust or fumes should be correctly used
andmaintainedinaccordancewiththemanufacturer’sinstructions.
• Select, maintain and replace the consumable/inserted tool as
recommended in these instructions, to prevent an unnecessary
increase in dust or fumes
• Use respiratory protection as instructed by your employer or as
required by occupational health and safety regulations;
7.2.2.11 NOISE HAZARDS

increase in vibration levels;
• Support the weight of the tool in a stand, tensioner or balancer,
becausetheoperatorcanthenusealightergriptosupportthetool.
• Hold the tool with a light but safe grip taking account of the
required hand reaction forces, because the risk from vibration is
generally greater when the grip force is higher.
7.2.3 ADDITIONAL SAFETY INSTRUCTIONS FOR PNEUMATIC
POWER TOOLS - AIR SUPPLY & CONNECTION HAZARDS
• Air under pressure can cause severe injury.
• Always shut o air supply, drain hose of air pressure and discon-
nect tool from air supply when not in use, before changing acces-
sories or when making repairs.
• Never direct air at yourself or anyone else.

AIR COMPRESSOR AND AIR TOOL SAFETY
1. Risk of Bursting. Do not adjust the regulator to result in output
pressuregreaterthanthemarkedmaximumpressureofthisair
tool.
2. Ensure the hose is free of obstructions or snags. Entangled or
snarled hoses can cause loss of balance or footing and may
become damaged.
3. Never leave a tool unattended with the air hose attached.
4. Do notoperate thistoolif it doesnotcontaina legiblewarning
label.
5. Do not continue to use a tool or hose that leaks air or does not
function properly.
6. Never direct a jet of compressed air toward people or animals.
7. Protect your lungs.Wear a face or dust mask if the operation is
dusty.
WARNING: Some dust created by power sanding, sawing,
grinding,drillingandotherconstructionactivitiescontains
chemicals known to cause cancer, birth defects or other
reproductiveharm.Someexamplesofthesechemicalsare:
Lead from lead based paint, crystalline silica from bricks
and cement and other masonry products, arsenic and
chromium from chemically-treated lumber.
Your risk from those 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

Important Warnings - Die Grinders
Specications
1. Only use mounted grinding stones or mounted carbide burrs that meet ANSI standards, ISO standards or both.
2. Never adjust the die grinder, adjust the collets or change the mounted stones or mounted burrs unless the air supply and air hose is
disconnected from the die grinder.
3. Onlypersonneltrainedinthecorrectmethodstoadjustcolletsandchangemountedstonesandmountedburrsshouldconductthese

Installation
1 Cleaning the air hose
□A3/8"airhoseisrequired,withamaximumlengthof25ft.
□Clean the air hose of accumulated dust and moisture
before connecting it to the air supply.
NOTE: If a longer air hose is required, connect a 1/2" air
hose to the 3/8" air hose to ensure the die grinder has the
necessary air supply.
Ensure the air line is shut-o and drained of air before removing this tool for service or changing sockets. This will prevent the tool
from operating if the throttle is accidentally engaged.
LUBRICATION
□An in-line lter-regulator-lubricator is recommended as it increases tool life and keeps the tool in sustained operation.
□Regularly check and ll the in-line lubricator with air tool oil. Avoid using excessive amounts of oil.
□Adjust the in-line lubricator by placing a sheet of paper next to the tool’s exhaust ports and holding the throttle open
approximately 30 seconds. The lubricator is properly set when a light stain of oil collects on the paper.
□If it is necessary to store the tool for an extended period of time (overnight, weekend, etc.), generously lubricate the tool
through the air inlet. Run the tool for approximately 30 seconds to ensure the oil is evenly distributed throughout the tool.
Store the tool in a clean and dry environment.
□Recommended lubricants: Air tool oil or any other high grade turbine oil containing moisture absorbent, rust inhibitors,
metal wetting agents, and an EP (extreme pressure) additive.

Troubleshooting
Problem Possible Cause Solution
The tool runs slowly or will not
operate.
There is grit or gum in the tool. Flush the tool with air tool oil or gum solvent.
The tool is out of oil. Lubricate the tool according to the lubrication
instructions in this manual.
The air pressure is low. □Adjust the regulator on the tool to the
maximum setting.
□Adjustthecompressorregulatortothetool’s
maximum setting of 90 psi.
The air hose leaks. □Tighten and seal the hose ttings with pipe
thread tape if leaks are found.
The air pressure drops. □Ensure the hose is the proper size. Long
hosesortoolsusinglargevolumesofairmay
require a hose with an I.D. of ½" or larger
depending on the total length of the hose.
□Do not use a multiple number of hoses
connected together with a quick connect

There is moisture blowing out
of the tool’s exhaust.
There is water in the tank. □Drain the tank. (See the air compressor
