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.

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.

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).

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.

2.1 Mounting the Grinder to the Workbench
Before attempting to use this grinder, it should be properly mounted to a workbench or grinding stand.
CAUTION Bench grinders vibrate. Grinder movement during high-speed rotation may cause
Injury or damage to the workpiece or operator. Mount the grinder securely to a sturdy workbench
or grinding stand.
1. Position the grinder on the workbench.
2. Mark the workbench through the two mounting holes located in the grinder base.
3. Drill holes in the workbench at the marks.
4. Using two long bolts, washers, locking washers and nuts (not supplied), secure the
grinder to the workbench.
2.2 Mounting the Wheels
Wheels are mounted using a 3/8-24 button head cap screw. at screw is a le hand thread on the le side
(turn clockwise to loosen), and right hand thread on the right side.
Be sure that the at 5/8” washer is always used between the wheel and the snap ring. is washer prevents the
wheel from pushing the snap ring over and contacting the grinder (see following diagram).
Your Tradesman has the largest possible sha that can be t into a motor this diameter and still have room for
brushes.e sha diameter internally is 0.6875” and ground down at nal assembly to 0.6248“ for a 5/8” arbor
and close-to-zero runout.
Given this engineering circumstance, the sha mounts an extra heavy duty snap ring in place of a shoulder.
is snap ring is good for 1400 lbs of shear when shouldered with a strong, precise bore that is just slightly
larger than the sha by 0.0004”. ere is NO countersink on the face that bears agains the snapring allowing
it to develop maximum shear. See the following diagram.
Care should be taken to ensure that only factory certied washers come in contact with the snap ring. e
3/8”-24 button head wheel bolts are designed to apply the appropriate resisting force to drive the wheels on
your grinder.

Tool Grinder Hub
is hub is used to adapt the 5/8” sha of the Tradesman to a 1.25” tool grinder hub to mount our machin-
ist and specialty wheels. e hub is reversable: mount thicker wheels with the hub oriented with the ange
inside, and thinner wheels like the cut o wheels, with the ange outside. is exposes the shorter 1.25” hub.

e 2-1/2” long spindle extension can be used for felt bung wheels. It is designed to t over inner prole of
an 8” Tradesman Plated Grinding Wheel. It can be used on either side and requires a long 3/8-24 scew to reach
through the extension to the motor sha and that would be a le hand thread on the le side of the grinder.To
install remove wheel cap and screw from wheel and place the extension securely over the wheel. Mount felt or

e Tradesman Grinders feature 1/4-28 mounting holes in the side plates for mounting various attachments.
Your Tradesman is supplied with four 1/4-28 Socket Head Cap Screws with dual-lobed thumb screws for toolless
use. ese can be replaced with any 1/4-28 screw. e bottom one is a pivot post while the top one is used to lock
the arm at a certain swing position. Tighten each according to your needs.
Standard Rest, Mitre Rest Jig Plate (T-MRJ) and Mitre Rest
Jig Plate with Feed (T-MRF)
e standard rest, the Mitre Rest and the Mitre Rest with y Axis Feed all mount similarly to a tool rest support
arm with a ratchet lever arm. Note: On the Tradesman Machinist the support arm is red to show it is shorter
than the Tradesman 8, due to the smaller wheel diameter on the Machinist.
T-MRF uses a unique tool rest support arm that mounts a 1/4-28 lead screw assembly. e T-MRF is the T-MRJ
with the addition of the feed assembly.

V-Block for Flats (T-WF)
e V-Block is mounted like the other rests using the 1/4-28 lever ratchet. It is designed to quickly put Weldon
set screw ats into carbide end mills. Care should be taken to secure the tool to the V-Block with a clamp so that
it doesn’t shi during grinding. Tension the pivot screw and swing screw on the support arm suciently so that
there is minimal play while allowing the tool rest to swing the V-Block forward to make the at. e V-Block
isn’t designed for carbide cut o so be sure to clamp the tool if performing this operation.
2.5 Tool Rest Adjustments and Installation
Tool rest adjustment is achieved using thumb screw and or button head cap screw and included hex key.
Before tightening the screws, adjust the gap between the grinding wheel and the work rest to a maximum of
1/8th” (3.2 mm). Tighten securely. To prevent the workpiece from being pulled and caught between the tool rest
and the wheel, readjust the tool rest position whenever necessary to maintain the 1/8th” (3.2 mm) distance.

Tormek Bracket (T-TB, TE-TB for Edge)
Remove the standard tool rest support arms to mount the Tormek Bracket which has its own longer support
arms. You can use the same mounting screws as used on the standard rests.
Note: For most Tormek jigs the wheel guards probably need to be repositioned so that the opening is at the top
of the wheel. If not equiped with thumb screws, the wheel guard is mounted with two socket head cap screws
and your grinder should be supplied with a 9/64ths hex key for these screws.
Water Bath Kit
e Tradesman Edge can be equiped with a water bath kit similar to that used on the Tormek machines. ese
water baths are machined to hook on the the side of grinder and li o for easy removal. is requires that the
grinder be sitting on a riser to provide the cleraance to drop the water bath. Wheel guard is removed. RPM
should be kept to minimum.
Universal Rest for Tormek Attachments
ere are several options for your tool rest for Tormek attachments that are set the same way, with red lock-
ing set screws in the bracket. Use your ocial Tormek US-105 Support, e similar Tradesman support (T-
US105), the 26” Tradesman Edge Twin Support (TE-US105), or the short 6” bar rest (T-BR) which mounts
without the Tormek Bracket using a 1/4-28 screw.

Installing an Abrasive Belt
Check to see if your belt has directional arrows and observe any manufacturer recomendations. Turn the
grinder o. With one hand, grasp the tensioning handle, opposite the upper pulley and rotate it towards you.
is will release tension on the belt for installation. With your other hand center the belt over both pulleys
and release the tension handle. Roll the belt in your desired direction by hand to check the tracking before
you turn on the grinder. Once the belt tracking is set so that the belt stays on the pulleys over several rota-
tions it is safe to turn on the grinder in your desired direction.
If static electricity is experienced around the belt, try applying foil tape to the smart platen. Remove Teon
tape before applying the foil tape.
Reversing the Belt Sanding Attachment
If your grinder is equiped with the reverse feature --- Check to see if your belt has directional arrows. Turn o
the grinder and run the belt in the reverse direction by hand to see if the tracking needs to be adjusted. If so,
use the supplied hex key to adjust the tracking set screw. Once the belt tracking is set so that the belt stays on
the pulleys over several rotations by hand it is safe to turn on the grinder in your desired direction. Fine tune
tracking using 1/8 turns of the set screw.
Tracking the Belt Sanding Attachment
Use the supplied hex key to adjust the tracking set screw.
