Machine Operation:
The Variable Frequency Drive (VFD) is
designed to allow the user to operate the
equipment on either single phase or
three phase power
for the 3HP model
.
The equipment is able to operate on
either 50 Hz or 60 Hz frequencies.
The
VFD will automatically adjust for phase
or frequency input
which will raise or
lower head speed on the machine.
LED
DISPLAY – Shows PAD speed
when
machine is running and says stop when
plugged in but not running.
Starting the equipment:
Apply downward pressure on the handle
to alleviate some pressure off of the tools
and press the green or blue start button.
Once the equipment gets started, gently
release the downward pressure and start
grinding.
The equipment is designed to rotate the
tooling in either the forward direction
(green button) or reverse direction (blue
button) depending on operating needs.
Use the equipment in the forward rotation
mode (green button) unless reverse
rotation is needed. This will ensure consis-
tent tool wear and tool profile. The use of
the equipment in the reverse rotation is
only needed when surface being finished
is uneven and causes the equipment to
pull in an undesired direction or when the
tooling is glazed and needs to be
re-dressed.
Use the knob, located
on
the right side
of
the handle control box
, to adjust speed of
equipment.Before
starting the equipment,
ensure that the speed is set to the
lowest speed available as displayed on
the VFD screen. Doing so will prevent
unexpected high speed start up which
could cause some tools to eject or
cause undesirable marks to the surface
being finished.
DO NOT LIFT THE EQUIPMENT OFF THE
GROUND WHILE STARTING!
Doing so can
cause the tools to release from the equip-
ment and cause damage to the surface
being finished and harm to the user!
Stopping the equipment:
To stop the equipment, turn speed control
knob to the slowest setting and push the
red stop button on the face of the handle
Changing tools and accessories:
Always turn off and disconnect power
from the machine when performing any
operations to the bottom of the machine!
When removing and inserting tool
plates or adapter plates, be sure to
inspect rubber grommets for signs for
wear and replace any damaged
grommets.
Using grommets that are damaged
or missing can cause unexpected
equipment operation and increase the
chance of tool plate / adapter plate
ejection or violent vibration leading to
loss of control of equipment!
Handle adjustment:
To adjust the handle, pull
the hand
latch or step on foot latch
on the
handle and move handle up or down
to
the desired
position.
Avoid
stepping on or tangling handle
control cable when adjusting the handle
position. Make sure that the
latch
clicks
in place
