GENERAL SAFETY RULES
WARNING! Read and understand all
instructions. Failure to follow all instruc-
tions listed below, may result in electric
shock, re and/or serious personal injury.
SAVE THESE INSTRUCTIONS.
Work Area
1. Keep your work area clean and well lit.
Cluttered oors and dark areas invite
accidents.
2. Do not operate equipment in
explosive atmospheres, such as in the
presence of ammable liquids, gases or
dust. Grinding can create sparks which
may ignite the dust or fumes.
3. Keep bystanders, children, and
visitors away while operating equip-
ment. Distractions can cause you to lose
control.
Electrical Safety
4. Do not abuse the cord. Never use the
cord to pull the equipment or pull the
plug from an outlet. Keep cord away
from heat, oil, sharp edges or moving
parts. Replace damaged cords immedi-
ately. Damaged cords increase the risk
of electric shock.
5. When operating equipment outside,
use an outdoor extension cord marked
"W-A" or "W". These cords are rated for
outdoor use and reduce the risk of
electric shock.
6. Avoid accidental starting. Be sure stop
button is depressed before plugging in.
Starting equipment with your nger on
the start buttons or plugging in equip-
ment that have the buttons depressed
invites accidents.
Personal Safety
7. Stay alert, watch what you are doing
and use common sense when operating
equipment. Do not use equipment while
tired or under the inuence of drugs,
alcohol, or medication. A moment of
inattention while operating equipment
may result in serious personal injury.
8. Do not overreach. Keep proper
footing and balance at all times. Proper
footing and balance enables better
control of the equipment in unexpected
situations.
9. Use safety equipment. Always wear
eye protection. Dust mask, non-skid
safety shoes, hard hat, or hearing
protection must be used for appropriate
conditions. Ordinary eye or sunglasses
are NOT eye protection.
10. DO NOT Turn on equipment while
the machine is tilted back. Any tooling
fastened to the machine can eject and
become a lethal projectile.
Equipment Use and Care
11. The equipment is designed to
remove excess surface material. To
prevent damage to the equipment
and/or serious personal injury, beware
of protruding objects or other debris on
or embedded in the surface being
nished.
12. Disconnect the plug from the power
source before making any adjustments,
changing accessories, or storing equip-

ment. Such preventive safety measures
reduce the risk of starting the equip-
ment accidentally.
13. Maintain equipment with care. Keep
tools and accessories in good condition.
Properly maintained tools with sharp
cutting edges are less likely to fail and
are easier to control.
14. Check for binding of moving parts,
breakage of parts, and any other condi-
tion that may aect the equipment's
operation. If damaged, have equipment
serviced before using. Many accidents
are caused by poorly maintained equip-
ment.
15. Use only tools and accessories that
are recommended by the manufacturer
for your equipment. Tools and accesso-
ries that may be suitable for style of
equipment, may become hazardous
when used on another style of equip-
ment.
SERVICE
16. DO NOT modify the machine. Modi-
cations will void warranty and could
result in unsafe operation of equipment.
17. Equipment service should be
performed only by qualied repair
personnel. Service or maintenance
performed by unqualied personnel
could result in a risk of injury.
18. When servicing equipment, use only
identical replacement parts. Use of
unauthorized parts may create a risk of
electric shock or injury.
USE PROPER EXTENSION CORD. Make
sure your extension cord is in good
condition. When using an extension cord,
be sure to use one heavy enough to carry
the current your product will draw. An
undersized cord will cause a drop in line
voltage resulting in loss of power and
overheating. For model HDX465 use
10gauge cord or larger. For model
HDX465HV use 12 gauge cord or larger. If
in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier
the cord.
SPECIFIC SAFETY RULES
DO NOT let comfort or familiarity with
product (gained from repeated use)
replace strict adherence to equipment
safety rules. If you use this equipment
unsafely or incorrectly, you can suer
serious personal injury.
1. Tools and accessories must be rated
for at least the speed stated on the
equipment serial plate. Tools and other
accessories running over rated speed
can y apart and cause injury.
2. Always use safety glasses or goggles.
Ordinary eye or sun glasses are NOT
safety glasses.
3. Make sure cord is clear of wheels and
cutting discs. Do not wrap cord around
your arm or wrist. If control of equip-
ment is lost, cord may become wrapped
around you and cause personal injury.
4. Adequate ventilation of your work
area is very important when using
equipment. Use a dust mask or appro-
priate respirator.
5. Due to the dusty nature during use of
this equipment, be sure to clean equip-
ment often to remove dust accumula-
tions. Carefully blow the dust out of the
motor, VFD and dust covered areas
frequently.
6. Always install the dust skirt before
operation.
7. Check the tools and accessories
carefully for cracks or damage before
operation. Replace cracked or damaged
tools or and accessories immediately.
8. Hold the equipment rmly with both
hands during operation.
9. Do not leave the equipment running
unattended.
10. Do not touch the tools immediately
after operation; they may be extremely
hot and could burn your skin.
WARNING: Misuse or failure to follow
the safety rules stated in this instruction
manual may cause serious personal
injury. SAVE THESE INSTRUCTIONS.

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 o 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 prole. The use of
the equipment in the reverse rotation is
only needed when surface being nished
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 nished 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 o 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

when the desired position is achieved.
Failure to check for positive engagement
could result in damage to the equipment
or injury to the user as the handle could
release unexpectedly when the machine
is being operated or tilted back!
VFD features:
The machine is outtted with a VFD
(Variable Frequency Drive) enabling the
user to select the desired operating speed.
The VFD also possesses many features
such as:
- Under voltage protection - Over current
protection
- 60Hz and 50Hz capability (international)
- Wide voltage range
(200-230V +/- 15% for 230V model)
(380-460V +/- 15% for 460V model)
- Soft start
- Speed display - Load display
- Current limiting
Maintenance:
General:
- Disconnect power before performing
any maintenance, cleaning, or repair to
your equipment!
- When the equipment is not in use,
make sure that the adapter plate assem-
blies have something attached to them
to protect the Velcro. Resting the
machine directly on unprotected Velcro
will crush the fastening material causing
the Velcro to become unusable.
Daily:
- Wipe down the equipment after every
job.
- Gently remove dirt and debris from the
Velcro hook material using a wire brush.
This will ensure maximum adhesion.
- Check that the handle bolts are tight.
- Vacuum or wipe underside of machine.
- Inspect plug ends for signs of carbon
deposits or arcing.
- Check all fasteners and tighten if
necessary.
Weekly:
- Inspect handle wires for damage.
- Blow o VFD heat sink with
compressed air. - Blow out VFD cooling
n fan(s) with low
pressure compressed air (30psi or less).
- Cleaning the fan(s) prevents fan failure
and
potential VFD overheating. Do not
over-speed
the fan(s) with compressed air!
- Blow o motor fan with compressed
air.
- Remove tool plate holders and wipe
down
bearing shields with a damp cloth. Do
not use any sharp object or abrasive pad
to clean the bearing shields. This can
compromise the bearing seal! Re-install
tool plate drivers using blue medium
strength thread locking compound.
- Using a soft scrub pad, remove any
excess dirt build up from the bottom
plate and back side of pad drivers.
- Inspect tool plate driver grommets for
signs of wear. Replace grommets that
show signs of extensive wear.
Monthly:
- Check all strain reliefs and make sure
they are tight so as to avoid cords being
pulled out of the VFD or handle.
- Remove tool plate drivers and inspect
threads to make sure that there are no
signs of cross threading or stripping.
- Clean and lubricate wheels.
- Clean and lubricate latch mecha-
nisms.

The VFD is protected from voltage
fluctua-tions within the specified
voltage range. Check voltage before
plugging in equip-ment to insure safe
operation.
If a machine is plugged into a power
source that is above the machine’s
maximum voltage capability (ex. 230V
model plugged into a 460V power
source) this will damage and/or destroy
the internals of the VFD and void
warranty!
