Ryobi PCL445 Manual Del Operador página 10

 Turn on the grinder and let the motor and grinding wheel
build up to full speed.
 Lower the grinder gradually until the grinding wheel
contacts the workpiece.
WARNING:
To prevent loss of control and possible serious personal
injury, always operate the grinder with both hands, keep-
ing one hand on the side handle.
 Keep the grinder tilted at an angle from 5° to 15° and
continuously moving at a steady, consistent pace.
NOTICE:
If the grinder is held in one spot too long, it will gouge
and cut grooves in the workpiece. If the grinder is held
at too sharp an angle, it will also gouge the workpiece
because of concentration of pressure on a small area.
 Use just enough pressure to keep the grinder from
chattering or bouncing.
NOTE: Heavy pressure will decrease the grinder's speed and
put a strain on the motor. Normally the weight of the tool
alone is adequate for most grinding jobs. Use light pressure
when grinding jagged edges or loose bolts where there is the
potential for the grinder to snag on the metal edge.
 Lift the grinder away from the workpiece before turning
off the grinder.
CUTTING WITH THE TOOL USING THE
REQUIRED ACCESSORY CUTTING WHEEL
GUARD (NOT INCLUDED)
See Figure 8, page 15.
Look for the accessory cutting wheel guard (p/n 204772004)
online or call 1-800-525-2579.
It is important to understand the correct method for cutting
with this tool. Refer to the figure in this section to learn the
correct way to handle the tool during a cutting operation.
WARNING:
Always attach the accessory cutting wheel guard to
the wheel guard when using a Type 1 straight or cut-off
wheel. Failure to use the guard insert could result in seri-
ous personal injury.
Always install the accessory cutting wheel guard before
performing cutting operations. When attached correctly, the
wheel guard insert and wheel guard provide protection on
both sides of the cutting wheel.
 Install wheel guard and cutting wheel.
 Place the edge of the guard insert closest to the label
over the edge of the wheel guard.
OPERATION
NOTE: The label on the guard insert should be pointing
away from the cutting wheel.
 Slide the guard insert over the grinding wheel and rotate
it until the tab snaps into place.
 To remove, pull the tab away from the wheel guard and
rotate guard insert off of the wheel guard.
WARNING:
To maintain proper control, always operate the tool with
both hands, keeping one hand on the side handle. Loss
of control could cause an accident resulting in possible
serious injury.
WARNING:
Since wheel is exposed on underside of work, keep
hands and fingers away from cutting area. Any part of
your body coming in contact with moving wheel may
result in serious injury.
WARNING:
Do not grind with the side of the cutting wheel. Abrasive
cutting wheels are intended for peripheral grinding,
side forces applied to these wheels may cause them to
shatter.
INSTALLING/REMOVING CUTTING WHEEL
See Figure 8, page 15.
 Place the guard on the shoulder of the bearing cap by
aligning index arrows on guard and bearing cap. Press
down on guard until it is fully seated.
 Depress the lever and rotate guard to the correct posi-
tion. Refer to Positioning the Wheel Guard.
NOTE: Be sure the raised ridge on the guard is seated
in the groove on the bearing cap.
 Place the disc flange onto the spindle. Make sure the
flats on the bottom of the disc flange are engaged with
the flats on the spindle.
 Place the cutting wheel over the spindle.
WARNING:
Always install a cutting wheel with the flat side of the
flange nut against the wheel. Failure to do so may cause
the cutting wheel to crack when tightening the flange
nut. This could result in serious in serious personal injury
because of loose particles breaking off and being thrown
from the tool. Do not overtighten.
 Thread the flange nut on the spindle with the raised, small
diameter portion of the flange nut facing up.
