FUNCTIONAL DESCRIPTION
FOREWORD
Porter-Cable angle grinders are designed for numerous grinding operations.
Typical applications are auto body grinding, smoothing welding beads,
removing gates and flash from castings, removing rust and the like.
NOTE:This tool is shipped completely assembled. Assembly time to
install HANDLE, WHEEL GUARD and GRINDING WHEEL is required
and should take 15 minutes or less. A 4mm hex wrench (supplied) is
required to install the WHEEL GUARD. The HANDLE serves as an
wrench to install the GRINDING WHEEL.
TO INSTALL AUXILIARY HANDLE
An auxiliary handle (H) Fig. 1 is furnished with this tool and can be installed
on either side or on top of the front housing. THIS HANDLE SHOULD BE
USED AT ALL TIMES TO MAINTAIN COMPLETE CONTROL OF THE
TOOL.
TO INSTALL WHEEL GUARD
A TYPE 27 wheel guard is furnished
with the tool. A TYPE 1 wheel guard is
available as an accessory. Both guards
are installed and adjusted in the same
manner.
Always use an approved and properly adjusted wheel guard.
DISCONNECT TOOL FROM POWER SOURCE.
1. Rest the tool on its back with spindle facing up.
2. Position the appropriate guard to the
tool so that the three bosses (A)
Fig. 2 (inside the guard mounting
clamp) are aligned with the three
notches (B) Fig. 2 in the mounting
flange of the grinder.
3. Seat the guard on the mounting
flange. Rotate the guard to a position
that will place the guard between the
operator and the grinding wheel (or
any other accessory requiring a guard). Tighten the clamp screw (A)
Fig. 3 to secure the guard in proper position for the grinding
application (see Fig. 4).
Always make sure that the wheel guard is positioned between
the operator and the wheel, so that flying chips or pieces of a wheel that
might break will be deflected away from the operator (see Fig. 4).
