Unplug the tool or place the switch in the locked or off position before making any
adjustments, changing accessories, or storing the tool. Such preventive safety measures
reduce the risk of starting the tool accidentally. Store idle tools out of reach of children
and other untrained persons. Tools are dangerous in the hands of untrained users.
Check for misalignment or binding of moving parts, breakage of parts, and any other
condition that may affect the tool's operation. If damaged, have the tool serviced before
using. Many accidents are caused by poorly maintained tools. Use only accessories that
are recommended by the manufacturer for your model. Accessories that may be suitable
for one tool may create a risk of injury when used on another tool.
Service
Tool service must be performed only by qualified repair personnel. Service or
maintenance performed by unqualified personnel may result in a risk of injury. When
servicing a tool, use only identical replacement parts.
Additional Safety Precautions
• Check that the rated speed of the accessories is equal to or greater than the rated speed
of the grinder (30,000 RPM).
• Handle and store grinding accessories with care.
• Inspect tool and accessories before operation. Do not use chipped, cracked or otherwise
defective products.
• Ensure that mounted wheels and points are fitted according to manufacturer's
instructions before operation.
• After mounting an accessory properly, turn on the tool and run it idle for 30 seconds in
a safe position. Stop immediately if there is considerable vibration or if other defects
are detected. Unplug and check the machine to determine the cause.
• Do not use separate reducing bushings or adapters to adapt large hole abrasive wheels.
• Ensure the work piece is properly supported.
• Do not use cut-off wheels for side grinding.
• Ensure that sparks resulting from use do not create a hazard. For example, that they do
not hit surrounding persons, or ignite flammable substances.
• Ensure that the vent is free of dust during operation. Unplug tool before cleaning dust
from the vent. To avoid damaging the inner components, do not clean the tool with
metal materials.
