SAFETY PRECAUTIONS
)
Read this manual and all the safety precautions before attempting to
operate WerkMaster machines. Failure to follow the safety precautions may
result in severe personal injury or death. This product is intended for
commercial use.
•Wear eye and ear protection at all times when operating WerkMaster
machines. Use only ANSI/OSHA-approved safety glasses to help prevent
eye injury.
•Wear appropriate clothing and footwear when operating WerkMaster
machines. Do not wear loose clothing or jewelry that may become entangled
in moving parts.
•Exposure to wood dust may cause health problems. To reduce your risk, work
in a well-ventilated area, use a dust control system such as an industrial-
style vacuum, and wear approved personal safety equipment, such as a dust
or particle respirator designed to filter out microscopic particles.
•Crystalline silica from bricks and concrete and other masonry products may
cause health problems. To reduce your risk, work in a well-ventilated area,
use a dust control system such as an industrial-style vacuum, and wear
approved personal safety equipment, such as a dust or particle respirator
designed to filter out microscopic particles.
•NEVER operate WerkMaster machines under the influence of drugs or
alcohol, when taking medications that impair the senses or reactions, or
when excessively tired or under stress.
•Only operate and maintain WerkMaster machines if you are trained in their
use and are in good physical condition and mental health. You must be
physically able to handle their bulk, weight and power.
•WerkMaster machines are to be operated by one person at a time. Maintain a
safe operating distance from other personnel. Keep bystanders a safe
distance away during operation by blocking off the work area in all directions
with roping, safety netting, or other material. Failure to do so may result in
someone being injured by flying debris or being exposed to harmful dust and
noise.
•Maintain a safe operating distance from flammable materials. Sparks from the
cutting action of WerkMaster machines may ignite flammable materials or
vapors.
•Unplug the WerkMaster’s power cord when not in use and before servicing or
changing tooling plates.
•DO NOT disconnect power by pulling the cord. To disconnect power, grasp
the plug, not the cord. Push the plug in and turn clockwise to engage; turn
counter-clockwise and pull to remove.
•DO NOT turn on the WerkMaster while it is tilted back. Any tooling fastened to
the WerkMaster may eject and become a lethal projectile.

•Ground this floor-finishing machine while in use to protect the operator from
electric shock. The machine is provided with a three-conductor cord and a
three-contact grounding type attachment plug to fit the proper grounding type
receptacle. The green (or green and yellow) conductor in the cord is the
grounding wire. NEVER connect this wire to other than the grounding pin of
the attachment plug.
•Be sure all safety decals on the machine may be clearly read and understood.
Replace damaged or missing decals immediately.
•Maintain WerkMaster machines in safe operating condition with all guards in
place and secure, all mechanical fasteners tight, all controls in working
order, and the grinder configured for the job application, whether concrete,
natural stone, wood or other surfaces.
•To prevent damage to your machine or severe personal injury, avoid
protruding slab inserts, nails, screws, Hilti anchors, rebar, embedded bolts or
any other debris, pipe extensions, machinery bases, or any objects that
transmit sudden shock to the grinding assembly.
•Inspect the discs carefully before installing. DO NOT use any discs that exhibit
signs of damage, as severe personal injury or damage to the equipment
could result.
•NEVER leave WerkMaster machines running unattended.
•Risk of Explosion: Grinding/polishing concrete surfaces and sanding/finishing
wood floors can result in an explosive mixture of fine dust and air. Use this
machine only in well-ventilated area free from any flame, match or
combustible materials.
Dust generated from sanding wood floors can spontaneously ignite or
explode. Promptly dispose of any sanding dust in a metal container clear of
any combustibles. Do not dispose in a fire.
DO NOT modify WerkMaster machines. Modifications will void the warranty
and may result in injury to persons and damage to the machine.
POWER AND CONNECTIVITY
WerkMaster machines are outfitted with a variable-frequency drive (VFD) that
allows the desired grinding speed to be selected. Along with controlling the
speed of the machine, the VFD features include the following:
•Undervoltage protection (damages most single-phase motors)
•+/- 10% voltage protection
•60 Hz and 50 Hz capability (international)
•Wide voltage range for 230V models (200–230V)
•Soft start (smaller generator requirements)
•Monitor pad speed display
!
!
!
NEVER open the VFD panel while plugged in or immediately after
unplugging the power cord. Severe injury or death may result.

WerkMaster machines come with a variety of different plug configurations. The
following table lists the plugs that are typically used.
!
!
!
!
!
!
WerkMaster machines come in a variety of voltage and phase configurations.
They are typically configured to operate on 208-230V single-phase power. They
are capable of operating on single-phase 208-230V power, as well as 110V
using a Breakout Box.
Pigtails are plug ends with unfinished bare wire on one end for hooking in to
panels. Pigtails are used when connectivity is unknown, when connecting to the
power grid of an unfinished building that has no power receptacles, or when
operating certain generators.
Certified electricians ONLY should make and/or install a pigtail in to a
panel.
When using the machines in a residential environment, source power may be
hard to find. Plug two 110V cords from the Quick 220 into the 110V wall outlet on
two (2) separate circuits on opposite sides of the panel. Plug the WerkMaster
machine into the Quick 220 adapter.
Draws power form either a stove/range or a dryer outlet and breaks it out into 2 x
20 Amp circuits that can be used to power both a WerkMaster machine and
auxiliary equipment such as a vacuum or the 110V Quad Box (sold separately).
The following table lists the requirements for power cords.

To change tooling:
1. Unplug the power cord from the twist lock plug (C). Ensure the handle is in its
full upright position (Fig 2). Tilt the machine back (Fig 3). Choose the
appropriate tooling holder attachment – magnetic Plug ‘N Go plate (D) for
Metal Bond tools or Foam Hook and Loop Adapter plate for polishing resins
and sandpaper. Insert the 2 shear pins through the compression foam pad
(E) into the rubber grommets on the pad driver (F). Attach the corresponding
tooling to the plate.
2. Return the machine to the upright position (Fig 2).
!
!
The dust skirt (G) serves as a seal for the bottom of the machine to act as a
vacuum chamber helping the dust stay contained under the machine. If the skirt
is too far from the ground, the dust containment is reduced.
To adjust the skirt:
1. Pull one end of the skirt off the machine until you reach the middle of the skirt.
2. Position the skirt until it is barely touching the ground and repeat with the other
end.
3. Pull the skirt snug. The two ends of the skirt should not touch. You may have a
gap of up to ½inch. Using the fabric connector cover the gap.
!
Avoid positioning the skirt too low as it will drag against the ground, wearing the
skirt out prematurely and possibly preventing smooth machine movement.
!
!
!
!
Changing Tools
)
Adjusting the Dust Skirt
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ))CAUTION)

0123!+!)
To adjust the handle, pull the pin (H). Adjust the handle to a comfortable
operating position. Release the pull pin and allow it to click into the positioning
hole.
!
!
!
Failure to check the pull pin is fully engaged could result in damage to the
machine or personal injury as the handle could release unexpectedly when the
machine is being operated or tilted back.
!
!
When the machine is first plugged in, a start-up screen (I) will flash STOP.
To start the machine, gently squeeze the activation lever (J) and press and
release the START button (A).
DO NOT lift the machine off the ground while starting it. Doing so could
cause the diamonds to release from the machine, resulting in damage to the floor
or personal injury.
The speed of the machine can be adjusted when the machine is running or
stopped. To adjust the speed, rotate the speed control knob (B) on the VFD
clockwise to speed it up, or counterclockwise to slow it down. Always start the
machine at the lowest speed and adjust as necessary.
Once the machine reaches the desired speed, the speed will remain constant as
long as the load applied remains below 100%. If the machine is running at speed
and the load begins to exceed 100%, the machine will reduce its speed as a
protective measure to try and alleviate the outstanding load. The current running
speed will be displayed. This happens under demanding conditions and is
normal.
If the machine is not able to maintain the minimum speed for more than 30
seconds the machine will turn off. This is a normal protective measure. To
prevent this from reoccurring alleviate some of the load and then resume
operation.
!
!
Let go of the activation lever.
When you unplug the machine, the screen will stay lit for a few seconds as the
VFD drains the power from its internal capacitors. This is normal.

To install and remove the pad driver on the bottom of the machine, you will need
a 17 mm socket wrench, a soft face mallet, and some medium-strength thread
locker (blue Loctite 243 or equivalent).
To remove the pad driver:
1. Slip the 17 mm socket wrench over the pad driver bolt and strike the wrench
with the soft face mallet in a counter-clockwise direction.
2. When installing a new pad driver or re-installing an existing one, apply a
generous amount of thread locker compound to the bolt and the threaded
drive shaft. Insert the bolt through the hole in the pad driver. Reapply thread
locking compound every time a pad driver is removed.
3. Line up the bolt to the threaded end of the shaft and start the first couple of
threads.
4. Once the bolt is engaged, make sure that the drive shaft is properly seated
within the pad driver slot before tightening the bolt all the way.
!
!
!
Failure to seat the pad driver could result in the pad driver slot being damaged,
the threads in the shaft being stripped, the machine leaving heavy tool marks,
and the tooling overheating.

MAINTENANCE
!
!
Disconnect power before performing any maintenance, cleaning, or repair
to your machine.
After wet operation, wash bottom of the machine thoroughly, failure to do
so may result in damaged bearing seals.
Do not use any sharp object or abrasive pad to clean the bearing seals.
This can compromise the bearing seals.
•Wipe down the machine after every job.
•Gently remove dirt and debris from the pad driver.
•Check to ensure the pad driver bolts are tight. If loose, remove pad driver and
apply blue thread locker (Locktite 243).
•Check grommets and replace if necessary.
•Vacuum, wash and thoroughly dry the underside of the machine.
•Inspect the plug ends for signs of carbon deposits and arcing.
•Check all fasteners and tighten if necessary.
•Inspect bearings seals around shaft for any wear or damage.
•Inspect the handle wires for damage.
•Blow off the VFD heat sink with compressed air.
•Using a soft scrub pad, remove any excess dirt build-up from the bottom plate
and back side of the pad drivers.
•Check all strain reliefs and make sure they are tight. (Strain reliefs are the
plastic nuts that secure the wires that come out of the handle and VFD.)
•Clean and lubricate wheels.
•Using an extremely light abrasive pad, remove any topical rust from the shafts.
