Battery And Charger Safety - Silverline 980960 Manual

EN
A grinding disc will gradually wear down during use,
•
reducing its size. If a disc becomes too small to work with
easily, stop using it and replace it with a new disc
Additional safety for superabrasives
• Superabrasives are generally inflexible and could shatter,
so must be handled with the utmost care. Damaged or
improperly mounted superabrasives are dangerous and can
cause SEVERE injury to the user and other people in the
vicinity
• Types of superabrasive wheels include diamond cutting
discs, welded metal discs, CBN discs etc. Choose your
superabrasive tool carefully, taking into consideration the
workpiece material, the tool dimensions and capabilities.
Make sure the tool does not exceed the maximum operating
speed of the superabrasive disc
NEVER use superabrasive cutting discs for side grinding, as
•
this might lead to the disc shattering
Superabrasive wheels have to be carefully inspected and
•
tested before mounting. Metal wheels should be subjected
to a sound test: hold the wheel on a mandrel or with a
finger inserted through the bore, then tap it with a non-
metallic object at several points and listen each time to the
sound produced. An intact wheel will produce a clear 'bell
like' metallic sound. Damaged wheels will give a dull,
chattering sound. If in doubt, DO NOT USE, MARK AS
DAMAGED AND DISCARD
• Make sure the tool's mounting flange is compatible with
the superabrasive wheel. Refer to the manufacturer's
mounting instructions
• ALWAYS conduct a test run after mounting, with no load
for at least 30 seconds, to determine if the wheel runs
balanced and does not produce excessive vibration. If it
does, switch off IMMEDIATELY, remove the disc, inspect, re-
mount and re-test if no damage is detected
• If planning on using the superabrasive wheel with a
coolant, liquid dust suppressant or lubricant, first check if
the wheel, tool and workpiece are compatible with wet
cutting and with the compound to be used. Always apply
liquid to an already running wheel, never to a non-moving
tool, as the unbalance could lead to the rupture of the
wheel. When switching off, remove the liquid supply first
and let the tool run at no-load, until centrifugal forces have
drained all liquid from the wheel. Dry off the wheel after
use, and prevent liquid from being absorbed into the wheel
Avoiding angle grinder burnout
Grinders are designed to work under load. Provided the motor is cooled
quickly, minimal wear or damage will occur.
•
DO NOT over work the angle grinder.
• If the grinder emits a burning smell, DO NOT stop the
grinder; instead, remove from load and allow to spin freely
for approximately 5-10 seconds at high speed to cool the
motor before continuing work.
•
Repeat the removal of the grinder from load intermittently
to keep the tool cool during use.
If a grinder is slowing down on sticky material whilst under load:
•
Check the correct grinding wheel type is being used
• Make shallower passes across the material

Battery and Charger Safety

Use the Battery Charger correctly
•
Refer to the section of this manual relating to use of the
Battery Charger (18) before attempting to charge the
Battery (8)
• Do not attempt to use the Battery Charger with any
batteries other than those supplied.
• Keep your Battery Charger clean; foreign objects or dirt may
cause a short or block air vents. Failure to follow these
instructions may cause overheating or fire
•
If the supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified
persons in order to avoid a hazard
•
Examine the Battery Charger regularly for damage,
especially the cord, plug and enclosure. If the Battery
Charger is damaged, it must not be used until it has been
repaired
•
Children should be supervised to ensure that they do not
play with the appliance
WARNING: Do not attempt to recharge non-rechargeable batteries.
Battery Safety
WARNING: Li-ion batteries, if incorrectly used, stored or charged are a
fire, burn and explosion hazard.
•
Keep the battery out of reach of children
• Only charge Li-ion batteries designed specifically for this
charger
• Only use Li-ion batteries provided with this product or
specifically designed to be compatible
•
Allow batteries to cool for 15 minutes after charging or
heavy use. Failure to follow these instructions may cause
overheating or fire
• When not in use batteries should be stored at room
temperature (approximately 20˚C)
• Ensure battery contacts cannot accidentally short in
storage. Keep batteries clean; foreign objects or dirt may
cause a short. Keep away from other metal objects, for
example paperclips, coins, keys, nails and screws
•
Under abusive conditions, liquid may be ejected from the
battery. This liquid may cause skin irritation or burns. Avoid
contact. If contact accidentally occurs, flush with water. If
liquid contacts eyes, seek medical help
•
Do not open, disassemble, crush, heat above 60°C or
incinerate. Do not dispose of in fire or similar
•
Do not get batteries wet or immerse in water
Battery & charger safety features
The Battery and Charger are fitted with a number of safety features which
may be triggered during charging or operation:
• Over-charge protection: Charger automatically switches off
when the Battery has reached full charge capacity,
protecting the internal components of the battery
•
Over-discharge protection: Prevents the Battery from
discharging beyond the recommended lowest safety
voltage
•
Over-heat protection: Sensor switches off if the Battery
becomes too hot during operation. This can happen if the
tool is overloaded or being used for extended periods of
time. Up to 30 minutes cooling time may be required
depending on the ambient temperature
•
Overload protection: Battery temporarily stops if it is
overloaded or the maximum current draw is exceeded,
protecting the internal components. The Battery will
resume normal operation when the current draw returns to
a normal safe level. This may take a few seconds
•
Short circuit protection: The Battery will stop working
immediately if a short circuit occurs, this prevents damage
to the Battery or tool
