NOTICE  
Standard Safety Instructions  
1. THOROUGHLY READ THE INSTRUCTION MANUAL BEFORE OPERATING YOUR MACHINE. Learn the  
applications, limitations and potential hazards of this machine. Keep the manual in a safe and con-  
venient place for future reference.  
2. KEEP WORK AREA CLEAN AND WELL LIGHTED. Clutter and poor lighting invite potential hazards.  
3. GROUND ALL TOOLS. If a machine is equipped with a three-prong plug, it must be plugged into a  
three-hole grounded electrical receptacle or grounded extension cord. If using an adapter to aid in  
accommodating a two-hole receptacle, ground using a screw to a known ground.  
4. WEAR EYE PROTECTION AT ALL TIMES. Use safety glasses with side shields or safety goggles that  
meet the appropriate standards of the American National Standards Institute (ANSI).  
5. AVOID DANGEROUS ENVIRONMENTS. Do not operate this machine in wet or open flame environ-  
ments. Airborne dust particles could cause an explosion and severe fire hazard.  
6. ENSURE ALL GUARDS ARE SECURELY IN PLACE and in working condition.  
7. MAKE SURE SWITCH IS IN THE OFF POSITION before connecting power to machine.  
8. KEEP WORK AREA CLEAN, free of clutter, grease, etc.  
9. KEEP CHILDREN AND VISITORS AWAY. Visitors must be kept at a safe distance while operating

12.DO NOT FORCE TOOL. The machine will do a safer and better job at the rate for which it was  
designed.  
13.USE CORRECT TOOL. Do not force machine or attachment to do a job for which it was not  
designed.  
14.WEAR PROPER APPAREL. Do not wear loose clothing, neck ties, gloves, jewelry, and secure long  
hair away from moving parts.  
15.REMOVE ADJUSTING KEYS, RAGS, AND TOOLS. Before turning the machine ON, make it a habit to  
check that all adjusting keys and wrenches have been removed.  
16.AVOID USING AN EXTENSION CORD. But if you must use one, examine the extension cord to ensure  
it is in good condition. Immediately replace a damaged extension cord. Always use an extension  
cord that uses a ground pin and connected ground wire. Use an extension cord that meets the amp  
rating on the motor nameplate. If the motor is dual voltage, be sure to use the amp rating for the  
voltage you will be using. If you use an extension cord with an undersized gauge or one that is too  
long, excessive heat will be generated within the circuit, increasing the chance of a fire or damage  
to the circuit.  
17.KEEP PROPER FOOTING AND BALANCE at all times.  
18.DO NOT LEAVE MACHINE UNATTENDED. Wait until it comes to a complete stop before leaving the  
area.  
19.PERFORM ALL MACHINE MAINTENANCE. Follow lubrication and accessory attachment instructions  
in the manual.  
20.KEEP MACHINE AWAY FROM OPEN FLAME. Operating machines near pilot lights or open flames  
creates a high risk if dust is dispersed in the area. Dust particles and an ignition source may cause  
an explosion. Do not operate the machine in high-risk areas, including but not limited to, those  
mentioned above.  
21.IF AT ANY TIME YOU ARE EXPERIENCING DIFFICULTIES performing the intended operation, stop  
using the machine! Then contact our service department or ask a qualified expert how the opera-  
tion should be performed.  
22. HABITS—GOOD AND BAD—ARE HARD TO BREAK. Develop good habits in your shop and safety will  
become second nature to you.

Additional Safety Instructions for Grinder  
READ and understand this  
entire instruction manual  
before using this machine.  
Serious personal injury  
may occur if safety and  
operational information is  
not understood and fol-  
lowed. DO NOT risk your  
safety by not reading!  
USE this and other machinery with caution  
and respect. Always consider safety first,  
as it applies to your individual working  
conditions. No list of safety guidelines can  
be complete—every shop environment is  
different. Failure to follow guidelines could  
result in serious personal injury, damage  
to equipment or poor work results.  
1. EYE PROTECTION. Grinding causes small particles to become airborne at a high rate of speed.  
ALWAYS wear safety glasses when using this machine.  
2. MOUNTING TO BENCH/STAND. An unsecured grinder may become dangerously out of control dur-  
ing operation. Make sure grinder is FIRMLY secured to a bench/stand before use.  
3. WHEEL SPEED RATING. Wheels operated at a faster speed than rated for may break or fly apart.  
Before mounting a new wheel, be sure the wheel RPM rating is equal or higher than the speed of  
the grinder.  
4. WHEEL FLANGES. Only use the flanges included with the grinder when mounting wheels. Other  
flanges may not properly secure the wheel and cause an accident.  
5. RING TEST. Perform a “ring test” on grinding wheels before installation to ensure that they are  
safe to use. A wheel that does not pass the ring test may break or fly apart during operation.  
6. STARTING GRINDER. If a wheel IS damaged, it will usually fly apart shortly after start-up. To  
protect yourself, always stand to the side of the grinder when turning it ON, allow it to gain full  
speed and wait for at least 1 minute before standing in front of it.  
7. LUNG PROTECTION. Grinding produces hazardous dust, which may cause long-term respiratory  
problems if breathed. Always wear a NIOSH approved dust mask or respirator when grinding.  
8. SIDE GRINDING. Grinding on the side of wheels can cause them to break and fly apart—unless the  
wheel is rated for side grinding.  
9. TOP GRINDING. Grinding on the top of wheels greatly increases the risk of workpiece kickback.  
Always grind on the downward part of the wheel.  
10. HAND/WHEEL CONTACT. Grinding wheels have the capability of removing a lot of skin fast. Keep  
a firm grip on the workpiece and position your hands a safe distance away when grinding. Avoid  
wearing gloves as they may get caught in the grinding wheel and cause even more serious entan-  
glement injuries.  
11. TOOL REST POSITION. If the tool rest is too far away from the wheel, the workpiece may be  
pulled down, causing loss of control and pulling your hand into the grinding wheel. Keep the tool  
rest within 18" from the wheel when operating.

ELECTRICAL  
110V Operation  
Your bench grinder needs a 110 volt power supply. When  
choosing a power supply outlet for the Model M1107  
bench grinder, use a circuit that is protected with a 15  
amp circuit breaker or fuse. Keep in mind that a circuit  
being used by other machines or tools at the same time  
will add to the total load being applied to the circuit.  
Add up the load ratings of all machines on the circuit. If  
this number exceeds the rating of the circuit breaker or  
fuse, use a different circuit.  
This equipment must be grounded.  
Verify that any existing electrical out-  
let and circuit you intend to plug into  
is actually grounded. If it is not, it  
will be necessary to run a separate 12  
AWG copper grounding wire from the  
outlet to a known ground. Under no  
circumstances should the grounding  
pin from any three-pronged plug be  
removed or serious injury may occur.  
Extension Cords  
When it is necessary to use an extension cord, use the  
following guidelines:  
Use cords rated for Standard Service.  
Never exceed a length of 50 feet.  
Use cords with 14 ga. wire or bigger.  
Insure cord has a ground wire and pin.  
Do not use cords in need of repair.  
Grounding  
This grinder must be grounded! The electrical cord sup-  
plied comes with a grounding pin. Do not remove it (see  
Figure 2). If your outlet does not accommodate a ground  
pin, have it replaced by a qualified electrician or have  
an appropriate adapter installed.  
Figure 2. Never remove the grounding  
Note: When using an adapter, the adapter must be  
grounded.

Shop Preparation  
Working Clearances: Consider existing and  
anticipated needs, size of material to be processed  
through the machine, and space for other machinery  
when establishing a location for your new machine.  
Lighting: Lighting should be bright enough to  
eliminate shadow and prevent eye strain.  
Electrical: Electrical circuits must be dedicated or  
large enough to handle amperage requirements.  
Outlets must be located near each machine, so  
power or extension cords are clear of high-traffic  
areas. Follow local electrical codes for proper  
installation of new lighting, outlets, or circuits.  
MAKE your shop “child safe.Ensure  
that your workplace is inaccessible to  
youngsters by closing and locking all  
entrances when you are away. NEVER  
allow untrained visitors in your shop  
when assembling, adjusting or operat-  
ing equipment.  
Mounting  
The bench grinder must be mounted to a workbench to  
avoid accidental tipping. If you intend on using the grind-  
er for portable applications, mount it to a heavy plywood  
base (at least 1" thick) that is wide enough to prevent  
tipping or rocking during use, then clamp the plywood  
base to the workbench or table.  
6"  
Holes are 516"  
To mount the bench grinder, do these steps:  
Diameter  
1. Determine the surface or object to which you will  
mount your grinder, and obtain the needed hard-  
ware for your mounting application.  
Figure 5. Bench grinder mounting bolt  
pattern.  
2. Fasten the grinder to your supporting surface, using  
the dimensions in Figure 5. DO NOT overtighten the  
mounting bolts or you will crack the base.  
3. Check the stability of the mounted grinder to make  
sure it is stable enough to be used safely.  
4. Always make sure the grinder is bolted or clamped  
to the workbench, table, or grinder stand before  
use.

Tool Rest and Eye Shield  
The tool rest supports the workpiece during grinding.  
Certain types of grinding may require jigs or accessories  
to assure the proper angle of the workpiece against the  
wheel.  
The eye shield must be installed and positioned between  
the grinding wheel and your face during grinding. The  
eye shield is NOT a substitute for safety glasses or a  
safety face shield. You must wear ANSI approved face  
and eye protection.

Before installing the included grinding wheels, you must  
check them for integrity by performing a “ring test.”  
Hang on a string, then lightly tap the rim of the wheel  
with a piece of wood such as the handle of a hammer.  
The wheel should have a ringing or harmonic type of  
sound. If the wheel responds with a dull thud it may  
indicate that the wheel has cracks. Do not use a wheel  
that is suspected of having cracks, or if there are visual  
chips, nicks or dents in the wheel surface. This damage  
can lead to wheel failure, causing the wheel to fly apart  
at operating speed.  
Figure 6. Tool rest and eye shield  
assembly.  
NEVER assemble a grinding wheel on  
the arbor without paper or fiber discs  
between the wheel and the mount-  
ing flange. Omitting the discs can put  
undue stress on the wheel, causing it  
to crack and possibly fly apart.  
Always be sure to use a Type 1 wheel that is rated for  
operating at 1725 RPM or greater. Install the grinding  
wheel, paper disc, wheel flange, and nut in the order  
shown in Figure 7, and then attach the side cover.  
Note: The arbor shaft and nut on the left-hand side of  
the grinder is a left-hand thread, so tightening it will  
require turning it counterclockwise.

Test Run  
Once your machine is mounted and assembled, you should  
perform a test run to make sure it works properly.  
To perform a test run, do these steps:  
1. Make sure all tools are removed from the grinder  
area.  
2. Make sure the switch is in the OFF position.  
3. Plug the grinder into the power source.  
DO NOT investigate problems or adjust  
the bench grinder while it is running.  
Wait until the machine is turned OFF,  
unplugged and the spindle has come  
to a complete stop before proceed-  
ing!  
4. Turn the grinder ON. Under normal conditions, the  
grinder will make a humming noise, with only minor  
vibration.  
— If you suspect any problems, immediately turn  
the grinder OFF and refer to Page 15 to trouble-  
shoot and correct any problems before starting the  
grinder again.  
— If the source of an unusual noise or vibration is not  
readily apparent, contact our technical support  
for help at (360) 734-3482 or contact us online at

OPERATIONS  
General  
Your bench grinder will allow you to perform many types  
of grinding and buffing operations. However, the follow-  
ing section is not a complete guide for every possible  
use.  
We strongly recommend that you read books, trade mag-  
azines, or seek formal training before attempting any  
grinding or buffing operations in which you are not con-  
fident with. Above all, your safety should come first.  
This recommended research will pay off with increased  
safety, improved work results, and the knowledge to be  
a better metalworker.  
Operation of this equipment has the  
potential to propel debris into the air  
which can cause eye injury. Always  
wear safety glasses or goggles when  
operating a grinder. Everyday glasses  
or reading glasses are not safety glass-  
es. Be certain the safety glasses you  
wear meet the appropriate standards  
of the American National Standards  
Institute (ANSI).  
Grinding Operations  
NEVER grind non ferrous metals like aluminum,  
brass, copper, bronze, and others, or the grinding  
wheel will load up, overheat, and can explode dur-  
ing operation.  
DO NOT make adjustments while the  
grinder is running. Ensure that the  
switch is OFF, power is disconnected  
and moving parts have stopped before  
making adjustments. Failure to comply  
could result in serious injury or  
electrical shock hazard.  
Once the assembly and the test run have been  
completed, your bench grinder is ready for use.  
When mounting a new wheel, or when there is any  
concern about wheel integrity, stand away from the line  
of rotation of the wheel and then turn the grinder ON.  
Allow the grinder to operate for one minute. If there is a  
problem it will generally occur when the grinder is first  
started. If the grinding wheel is OK, rest the workpiece  
on the tool rest and ease the workpiece into the grinding  
wheel. Begin grinding without holding the workpiece in  
one spot, or it will cause uneven wear on the stone face.

Changing Grinding  
Wheels  
Before installing any grinding wheel you must check the  
structural integrity by performing a “ring test.” Hang the  
wheel on a string, then lightly tap the rim of the wheel  
with a piece of wood such as the handle of a hammer.  
The wheel should have a ringing or harmonic sound.  
If the wheel responds with a dull thud it may indicate  
that the wheel has cracks. Do not use a wheel that is  
suspected of having cracks, or if there are visual chips,  
nicks or dents in the wheel surface. This damage can  
lead to wheel failure, causing the wheel to fly apart at  
operating speed.  
Do not use a wheel that is suspected of having cracks,  
or if there are visual chips, nicks or dents in the wheel  
surface. This damage can lead to wheel failure where  
the wheel flies apart at operating speed. Always be sure  
to use a wheel which is rated for 3450 RPM or greater.  
Figure 8. Grinding wheel components.  
NEVER assemble a grinding wheel on  
the arbor without paper or fiber discs  
between the wheel and the flange.  
Omitting the discs can put uneven  
stress on the wheel causing it to crack  
and possibly fly apart. ALWAYS “ring  
test” a wheel before assembly to make  
certain it has no cracks or flaws.  
To change a grinding wheel, do these steps:  
1. DISCONNECT THE GRINDER FROM POWER!  
2. Disassemble grinder to the level shown in Figure 8.  
3. Hold the wheel from turning, and remove the arbor  
nut which holds the wheel on.  
Note: The arbor shaft and nut on the left hand side  
of the grinder is a left hand thread, so loosening it  
will require turning it clockwise.  
4. Install the new wheel in the order shown in Figure  
8 and tighten the arbor nut snugly, but do not over  
tighten or you will crack the wheel.  
5. Run a new wheel for at least 1 minute while stand-  
ing clear of the line of rotation. If a wheel does  
have defects it will generally fail as soon as it gets  
up to full speed.

MAINTENANCE  
General  
Check for the following conditions and repair or  
replace when necessary:  
Cracked or loose grinding wheel.  
Loose mounting bolts.  
Worn switch.  
Worn or damaged cords and plugs.  
Any other condition that could hamper the safe  
operation of this machine.  
MAKE SURE that your machine is  
unplugged during all maintenance pro-  
cedures! If this warning is ignored, seri-  
ous personal injury may occur.  
Lubrication & Cleaning  
This grinder has sealed bearings that require no user  
lubrication.  
The grinding wheel should be inspected before every  
use. Use the ring test method noted in Changing  
Grinding Wheels on Page 13 to verify the structural  
integrity. Take care in storing grinding wheels to keep  
them free from potential damage by being dropped, or  
having other items drop on them.  
Replace the wheel when the wheel diameter is reduced  
to 4". Operating at anything less than this diameter does  
not allow the proper surface speed for grinding or spac-  
ing of the tool rest and the eye shield, and the grinding  
wheel may fly apart.  
Depending on the type of grinding you do, the grinding  
wheel may require periodic dressing. There are several  
different types of wheel dressing devices available on  
the market. Use a suitable diamond or silicon carbide  
stick type dresser. Sweep it smoothly and evenly several  
times across the face of the wheel. Dressing restores the  
abrasive quality of the wheel surface, plus it will bring  
the wheel edge back to a square form. Refer to the  
instructions that accompany your dressing accessory for  
complete detail on wheel dressing.
