Operation - DeWalt D28114 Instruction Manual

CAUTION: Do not tighten the adjusting screw with the clamp lever
in open position. Undetectable damage to the guard or the mounting
hub may result.
CAUTION: If guard cannot be tightened by adjusting clamp, do
not use tool and take the tool and guard to a service center to repair
or replace the guard.

OPERATION

WARNING: To reduce the risk of injury, turn unit off and
disconnect it from power source before installing and removing
accessories, before adjusting or when making repairs. Before
reconnecting the tool, depress and release the trigger switch
to ensure that the tool is off. An accidental start-up can cause
injury.
Guards and Flanges
It is important to choose the correct guards and flanges to use with
the grinder accessories. See pages 10–12 for the correct accessories.
NOTE: Edge grinding and cutting can be performed with Type 27
wheels designed and specified for this purpose.
WARNING: Accessories must be rated for at least the speed
recom mended on the tool warning label. Wheels and other accessories
running over rated accessory speed may burst and cause injury.
Every unthreaded accessory must have a 7/8" (22.2 mm) arbor hole.
If it does not, it may have been designed for a circular saw and should
not be used. Use only the accessories shown on pages 10–12.
Accessory ratings must be above listed minimum wheel speed as
shown on tool nameplate.
Switches
CAUTION: Hold the side handle and body of the tool firmly to
maintain control of the tool at start up and during use and until the
wheel or accessory stops rotating. Make sure the wheel has come to
a complete stop be fore laying the tool down.
NOTE: To reduce unexpected tool movement, do not switch the
tool on or off while under load conditions. Allow the grinder to run
up to full speed before touching the work surface. Lift the tool from
the surface before turning the tool off. Allow the tool to stop rotating
before putting it down.
SOFT START FEATURE
The soft start feature allows a slow speed build-up to avoid an initial
jerk when starting. This feature is particularly useful when working in
confined areas. Current surge will also be reduced.

accidental unplugging, or power failure.
To turn the tool on, push the lock-off
lever (B) toward the back of the tool,
