Bosch 400 Series XPR - Manual (Page 3)

Store idle tools out of reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
Maintain tools with care. Keep cutting
tools sharp and clean. Properly main-
tained tools, with sharp cutting edges are
less likely to bind and are easier to control.
Any alteration or modification is a misuse
and may result in a dangerous condition.
Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tools
operation. If damaged, have the tool
serviced before using. Many accidents
are caused by poorly maintained tools.
Develop a periodic maintenance schedule
for your tool.
Use only accessories that are recom-
mended by the manufacturer for your
model. Accessories that may be suitable for
one tool, may become hazardous when
used on another tool.
Service
Tool service must be performed only by
qualified repair personnel. Service or
maintenance performed by unqualified per-
sonnel could result in a risk of injury. For
example: internal wires may be misplaced
or pinched, safety guard return springs may
be improperly mounted.
When servicing a tool, use only identical
replacement parts. Follow instructions in
the Maintenance section of this manual.
Use of unauthorized parts or failure to follow
Maintenance Instructions may create a risk
of electric shock or injury. Certain cleaning
agents such as gasoline, carbon tetrachlo-
ride, ammonia, etc. may damage plastic
parts.
SAFETY RULES FOR ROTARY TOOL
Accessories must be rated for at least the
speed recommended on the tool warning
label. Wheels and other accessories run-
ning over rated speed can fly apart and
cause injury.
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or
its own cord. Contact with a "live" wire will
make exposed metal parts of the tool "live"
and shock the operator. If cutting into existing
walls or other blind areas where electrical
wiring may exist is unavoidable, disconnect
all fuses or circuit breakers feeding this work-
site.
Do not operate the flexible shaft with a
sharp bend. Over bending the shaft can
generate excessive heat on the jacket or
hand piece. The recommended minimum is
6" radius.
Always disconnect the power cord from
the power source before making any
adjustments or attaching any acces-
sories. You may unexpectedly cause the tool
to start leading to serious personal injury.
Be aware of the switch location, when
placing the tool down or when picking the
tool up. You may accidentally activate the
switch.
Always hold the hand piece firmly in your
hands during the start-up. The reaction
torque of the motor, as it accelerates to full
speed, can cause the shaft to twist.
Always wear safety goggles and dust
mask. Use only in well ventilated area.
Using personal safety devices and working in
safe environment reduces risk of injury.
After changing the bits or making any
adjustments, make sure the collet nut and
any other adjustment devices are secure-
ly tightened. Loose adjustment device can
unexpectedly shift, causing loss of control,
loose rotating components will be violently
thrown.
Do not reach in the area of the spinning
bit. The proximity of the spinning bit to your
hand may not always be obvious.
Allow brushes to run at operating speed
for at least one minute before using
wheel. During this time no one is to stand
in front or in line with the brush. Loose
bristles or wires will be discharged during the
run-in time.
Wire and bristle brushes must never be
operated at speeds greater than
15,000/min. Direct the discharge of the
spinning wire brush away from you.
Small particles and tiny wire fragments may
be discharged at high velocity during the
“cleaning” action with these brushes and may
become imbedded in your skin. Bristles or
wires will be discharged from the brush at
high speeds.
Carefully handle both the tool and individ-
ual grinding wheels to avoid chipping or
cracking. Install a new wheel if tool is
