Congratulations on your purchase of the Tradesman
DC Variable Speed Bench Grinder. All Tradesman
Grinders feature the same 400W DC Motor and
control and plug in to regular household 110V AC
current (220V available).
We have a patent on low speed high feed grinding
with the Tradesman (variable speed, high torque
and super abrasive wheels). e Tradesman is the
only grinder designed to run plated-bond wheels.
It is not like using other grinders, period. With the
Tradesman you can grind carbide tools or Teon on
the same wheel because at 500 RPM, there’s nothing
threatening about it: you can take heavy cuts while
keeping the heat down.
Enjoy your new grinding experience. Give us a call if
you have any questions.

Quick Start Guide
ON/OFF
e ON/OFF power switch is located on the front of the grinder. It has a safety feature to default to the O
position when every power is disconnected.
1. Turn the speed dial to minimum setting before turning the grinder on.
2. Press the green button marked with a vertical bar to turn the grinder on.
3. Press the red button marked with a circle to turn the grinder o.
Reverse (if equiped)
e reverse switch is a three position rocker switch where up is forwards, down is reverse and the middle po-
sition cuts power to the motor ie. the grinder will appear to be o (on switch will remain engaged) and wheels
will not turn. Important: Do not go from forwards to reverse or vice versa while wheels are turning, this
could damage the circuit board. Wait for wheels to stop turning before you change wheel direction. See page 7.
Wheel Guards
Wheel guards are precision machined and secured to the grinder with two socket head cap screws. ese
screws can be loosened to readjust the guard if it is rubbing on the grinding wheel, or removed to reposition
the guard to it’s open-at-top position for Tormek.
Drive Pins
Tradesman Grinders equiped with reverse feature drive pins (3/16” diameter pins) that t through the wheel
cap and into a receiving hole in the motor sha. is ensures that hub caps and screw don’t loosen during op-
eration. If you have a reverse machine, always check that these pins are in place before you start. See page 6.
Fuses
e Tradesman Grinder uses a 8A Slow Blow fuse. It is located at the back of the machine inside the AC recep-
tacle. It can be accessed by removing the power cord and prying the drawer out. e grinder ships with a spare
fuse also in this location. See page 7.
Red Caps are used to indicate adjustment points.

DRIVE PINS
Drive Pins: On all Tradesman Grinders with Reverse capability (have a reverse switch on rear
of machine - see following page) drive pins are employed to secure the wheels to the sha.
ey pass through the cap and in to the sha and stop the cap from accidentally unscrewing
resulting in a wheel coming o during operation. Before use make sure that each wheel and cap
has it’s drive pin installed. Do not operate the grinder without drive pins installed. Failure to do
so could result in a grinding wheel coming o during operation. See the below diagram for a
review of the drive pin operation.

When using the sha extension, two drive pins are employed: one that locks the cap the exten-
sion and one that locks the extension to the spindle sha.

FUSES and REVERSE
Fuses: All Tradesman grinders are equiped with a fuse inside the AC re-
ceptacle at the rear of the machine. If a power surge is experienced this fuse
is designed to blow at 10A (10A Slow Blow). If your grinder isn’t turning on
when plugged in to a good power source this is the rst place to look. e
fuse can be accessed by unplugging the power cord from the grinder and
nding it in a small drawer inside the receptacle. e drawer can be levered
out with a small at head screw driver. e drawer also contains a spare
fuse.

Reverse Switch: If your gridner is equiped with a reverse switch note that
it is a three position rocker switch where up is forwards, down is reverse
and the middle position cuts power to the motor ie. the grinder will ap-
pear to be o and wheels will not turn.
Important: Do not go from forwards to reverse or vice versa while wheels
are turning, this could damage the circuit board. Wait for wheels to stop
turning before you change wheel direction.

For your own safety, read this instruction manual before
operating this machine.
1. Always use ANSI approved safety glasses when operating machinery. Everyday eyeglasses only have
impact resistant lenses - they are not safety glasses.
2. Always wear a NIOSH approved respirator when operating machinery that produces dust. Most types of
dust (wood, metal, etc.) can cause severe respiratory illnesses.
3. Always use hearing protection. Machinery noice can cause permanent hearing loss.
4. Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings, or jewelery that can catch in
moving parts. Wear protective hair covering to contain long hair and wear noon-slip footwear.
5. Never operate machinery when tired or under the inuence of drugs or alcohol. Be mentally alert at all
times when running mcachinery.
6. Do not overtighten spindle nuts. Overtightening these may cause the wheel to run out. Caps should be
snug.
7. Adjust tool rests whenever necessary to maintain a distance of 1/8” (3.2mm) from the grinding wheel.
8. Keep wheel guards in place and working properly
9. During each start up, stand to one side of the grinder and switch it ‘On’. Let the grinder run for 60 sec-
onds to detect any aws.
10. Always ensure that the work area is clear of any ammable materials, liquids or gasses, because the use
of this tool may create sparks.
No list of safety guidlines is complete. Every shop is dierent. Always consider safety rst, as it applies to
your individual working conditions. Use this machinery with caution and respect. Failure to do so could
result in serious persal injury, damage to equipment, or poor work results.

Before You Start - Electrical
In the event of a malfunction or short circuit, grounding provides the path of least resistance for electri-
cal current, and reduces the risk of electric shock for the operator. is tool is equipped with an electric
cord that has an equipment grounding conductor and a grounding plug. e plug MUST be plugged
into a matching outlet that is properly installed and grounded in accordance with ALL local codes and
ordinances.
DO NOT MODIFY THE PLUG PROVIDED. If it will not t the outlet, have the proper outlet installed
by an electrician.
IMPROPER CONNECTION of the equipment grounding conductor can result in increased risk of
electric shock. e conductor with the green insulation (with or without yellow stripes) is the equip-
ment grounding conductor. If repair or replacement of the electric cord or plug is necessary, DO NOT
connect the equipment grounding conductor to a live terminal.
CHECK with a qualied electrician or service personnel if you do not completely understand the
grounding instructions, or if you are not sure if the tool is properly grounded.
Use of Extension Cords
USE ONLY THREE-WIRED EXTENSION CORDS that have 3-prong plugs and 3-holed outlets that
accept the tool's plug. Repair or replace damaged or worn cords immediately.
Be sure your extension cord is properly wired and in good condition. Do not use damaged extension
cords. Always replace a damaged extension cord.
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.
e table below shows the correct size to use according to the cord length and the amperage draw of
the tool (specied on the nameplate). When in doubt, use the next heavier gauge. e smaller the gauge
number, the heavier the cord. (AWG = American Wire Gauge).

Page 10
Before You Start - Electrical (continued)
Use a separate electrical circuit for your tools. is circuit should not be less than a #12 gauge wire, and
should be protected with a 15A time-lag fuse or breaker. Before connecting the motor to the power
line, ensure the switch is in the OFF position and the electric current is rated the same as the current
stamped on the motor's nameplate. Running at a lower voltage will damage the motor, and this damage
is not covered' by warranty.
