G2438-6.5C
• Correct grinding wheel mounting is necessary to prevent
injury from broken wheels.
• Avoid mismatch between UNC and metric threads.
• Grinding wheels should be a free fit on the spindle to
prevent stress at the hole. Do not use reducing bushes to
fit large hole grinding wheels.
• Use only the flanges that come with the grinder for
mounting the grinding wheel. Flat washers or other
adapters may over stress the wheel. Always use heavy
paper blotter discs between the flanges and the grinding
wheel.
• If several flanges are supplied to fit different sizes and
types of abrasive, always fit the correct flange(s) for the
abrasive being used.
• When mounting cups, cones or plugs with threaded
holes, the spindle end must not contact the bottom of the
hole as it will stress the abrasive.
• Tighten the wheel on the spindle to prevent spin off
when the air grinder is turned off.
• Before grinding, test grinding wheel by briefly running
tool at full throttle. Be sure to use a barrier (such as un-
der a heavy work table) to stop any possible broken
wheel parts. Stop immediately if vibration is excessive.
Operating hazards
• Operators and maintenance personnel must be physically
able to handle the bulk, weight and power of the tool.
• Hold the tool correctly: be ready to counteract normal or
sudden movements – have both hands available.
• You can be cut or burned if you come into contact with
the accessory, grinding sparks or the work surface.
Avoid contact and wear protective equipment such as
gloves, apron and helmet.
• Avoid wheel jamming when cutting-off. Support the
workpiece on both sides of the cut line to prevent the
wheel becoming trapped. If jamming occurs, release the
throttle and ease the wheel free. Check the wheel is un-
damaged and properly secured before continuing.
• Never use cutting-off wheels for side grinding.
• Grinding sparks can ignite clothing and cause severe
burns. Ensure sparks do not land on clothing. Wear fire-
retardant clothing and have a bucket of water nearby.
• There is a risk of electrostatic discharge if used on plas-
tic and other non-conductive materials.
Repetitive motion hazards
• When using a power tool to perform work-related activi-
ties, the operator might experience discomfort in the
hands, arms, shoulders, neck, or other parts of the body.
• Adopt a comfortable posture whilst maintaining secure
footing and avoiding awkward or off-balance postures.
Changing posture during extended tasks can help avoid
discomfort and fatigue.
• Do not ignore symptoms such as persistent or recurring
discomfort, pain, throbbing, aching, tingling, numbness,
burning sensation, or stiffness. Stop using the tool, tell
your employer and consult a physician.

Noise and Vibration hazards
• High sound levels can cause permanent hearing loss and
other problems such as tinnitus. Use hearing protection
as recommended by your employer or occupational
health and safety regulations.
• Exposure to vibration can cause disabling damage to the
nerves and blood supply of the hands and arms. Wear
warm clothing and keep your hands warm and dry. If
numbness, tingling, pain or whitening of the skin occurs,
stop using tool, tell your employer and consult a physi-
cian.
• Hold the tool in a light but safe grip because the risk
from vibration is generally greater when the grip force is
higher. Where possible support the weight of the tool
with a balancer.
• To prevent unnecessary increases in noise and vibration
levels:
• Operate and maintain the tool, and select, maintain and
replace the accessories and consumables, in accordance
with this instruction manual;
• Use damping materials to prevent workpieces from
"ringing."
Workplace hazards
• Slip/Trip/Fall is a major cause of serious injury or death.
Be aware of excess hose left on the walking or work sur-
face.
• Avoid inhaling dust or fumes or handling debris from the
work process which can cause ill health (for example,
cancer, birth defects, asthma and/or dermatitis). Use dust
extraction and wear respiratory protective equipment
when working with materials which produce airborne
particles.
• Some dust created by power sanding, sawing, grinding,
drilling and other construction activities contains chemi-
cals known to the State of California to cause cancer and
birth defects or other reproductive harm. Some examples
of these chemicals are:
• Lead from lead based paints
• Crystalline silica bricks and cement and other ma-
sonry products
• Arsenic and chromium from chemically-treated rub-
ber
Your risk from these exposures varies, depending on
how often you do this type of work. To reduce your ex-
posure to these chemicals: work in a well ventilated area,
and work with approved safety equipment, such as dust
masks that are specially designed to filter out micro-
scopic particles.
• Proceed with care in unfamiliar surroundings. Hidden
hazards may exist, such as electricity or other utility
lines.
• Potentially explosive atmospheres can be caused by dust
and fumes resulting from sanding or grinding. Always
use dust extraction or suppression systems which are
suitable for the material being processed.
