SAFETY INSTRUCTIONS
1. ALWAYS WEAR EYE PROTECTION. A full-face visor is preferred. Any Belt/Disc Grinder can throw
foreign objects into the eyes.
2. AVOID CONTACT WITH BELT OR DISC. The abrasive belt when running is an aggressive cung tool.
Extra care should be exercised when using coarse grit belts because of their rapid cung acon.
3. KEEP CHILDREN AWAY. All visitors should be kept a safe distance from the work area.
4. BOLT THE BENCH GRINDER securely to the bench or supporng surface to stop it from pping over
or moving when in use.
5. DO NOT MOUNT the aachment protruding into walkways.
6. KEEP WORK AREA CLEAN. Cluered areas and benches invite accidents.
7. ALWAYS WEAR A DUST MASK to prevent dust inhalaon when adequate venlaon or extracon is
not available.
8. DO NOT WEAR LOOSE CLOTHING which may become entangled in the machine. Wear protecve
hair covering to contain long hair.
9. ALWAYS HOLD the work piece rmly when grinding and apply a light and steady pressure against
abrasive disc or belt.
10. ALWAYS GRIND ON THE DOWNWARD SIDE of the grinding disc. Grinding on the upward side of
the disc could cause the work piece to y out of posion, resulng in injury.
11. DO NOT USE BELTS THAT ARE DAMAGED, TORN, OR SHOW SIGNS OF WEAR.
12. ALWAYS INSTALL BELTS with arrows in the back of the belts poinng the correct direcon. Belts
with lap joints must be ed facing the correct direcon.

OPERATING INSTRUCTIONS
BELT CHANGING
To remove the belt, simply push down on the underside of belt to compress the tensioner assembly. The
catch will automacally hold the slide in the retracted posion. When replacing the belt simply release the
catch. Make sure that direconal belts are turning the correct direcon.
BELT TRACKING
Ensure the belt enrely covers the rubber contact wheel. Adjustments can be made when running or when
belt is rotated by hand. To adjust le, move tracking lever down. To adjust right, move lever up.
PLATEN GRINDING (HORIZONTAL OR VERTICAL)
It is important that the platen is not set too high. If belt is deected and rides up over the platen, this creates
an undue strain on the grinder, especially when starng. If platen is not oen used, it is beer to adjust it
slightly below the belt. A simple method to adjust the platen is to place a straight edge on top of the belt
between the contact wheel and drive pulley and raise platen so that it just touches the under side of belt.
DISC GRINDING
Disc grinding is well suited for shaping and general deburring work. Grind parts on the downward side of
the disc’s rotaon, so that dust and sparks are directed away from the operator’s face. For grinding small
parts, a secure work holding tool should be used to help prevent operator from contact with the grinding
disc surface. Abrasive disc grit should be matched to the amount of material intended to be removed. The
more quickly material can be removed, the less heat will build up in the part being ground. This will also
help preserve abrasive life. 80 – 180 grit discs are good for general deburring and chamfering operaons. For
heavy material removal use more aggressive 40 grit abrasive discs.
CONTACT WHEEL GRINDING, POLISHING, AND SANDING
Always grind on the lower half of the contact wheel, so that dust and sparks are directed away from the
operator’s face. For grinding small parts, a secure work holding tool should be used to help prevent operator
contact with the grinding belt surface. Abrasive belt grit should be matched to the amount of material
intended to be removed. The more quickly material can be removed, the less heat will build up in the part
being ground. This will also help preserve abrasive life. 80 – 180 grit belts are good for general deburring
and chamfering operaons. For heavy material removal use aggressive (24 – 40 grit) abrasive belts unl
desired shape is achieved. Finer grit belts should be ulized for removal of coarser grinding marks and
polishing operaons. Scotchbrite® belts are ideally suited for paint and rust removal operaons.
SLACK BELT
Slack Belt grinding is a method of belt grinding, sanding, or polishing where no backing is used behind the
belt. It is especially suitable for round and contoured work and some sharpening operaons. Slack belt
grinding can be performed on the underneath side of the belt opposite the platen. Belt grits of 180 to 400
are recommended due to the rapid cung acon of this method of grinding.

FITTING INSTRUCTIONS
1.
Install sloed adaptor plate using either 6mm bolt (3), 5mm bolt (5), or 4.8mm bolt (9) provided (image
2A). Use appropriate size washers under heads (1 or 12). The outer edge of the adaptor plate is tapered.
Face smallest side of taper away from grinder motor (image 2B).
Di sconnect grinder from power source. From the
right side of the grinder, remove wheel guards,
grinding stone, and any anges or washers used
with the factory stone. Retain factory arbor nut
for use with Multool drive drum.

NOTE: Some grinders may require the
use of addional washers between the
grinder and adaptor plate to clear bolt
heads in step 3. This may require the
use of longer bolts to get full thread
engagement in motor housing.

4
Install the tensioner arm using 8mm bolts (2) and washers (7) into the slots on the main bracket, keeping
the bolts slightly loose for future adjustments in step 6.
5. Install a 1/2” washer (13) or a 5/8” washer (11) on the grinder sha (image 5A). The drive drum features
a 5/8” bore, however a nylon bushing (10) is provided for 1/2” shas. Fit the drive drum by sliding over
the sha of the grinder (image 5B). If there is interference between the adapter plate bolts and drive
drum, add addional washers behind the drum to gain acceptable clearance. Use 1/2” (13) or 5/8” (11)
diameter washers under the arbor nut and ghten. If drive drum does not run true, use rubber or leather
mallet to tap on the inside edge of rim (image 5C) where run-out may occur.

For parts, tech support, belts, or discs contact Multool Grinders at 641-628-4253 or sales@multoolgrinders.com
Install the main bracket using bolts (8) through the three cut outs shown in image 3A. With head of
bolt facing the grinder motor, use 6mm nuts (6) and washers (12) and ght en evenly. The adaptor plate
should be ush with the main bracket as shown image 3B. If the Multool is to be used in a vercal
posion simply loosen nuts and tap main bracket to loosen. Swivel to desired posion and reghten
nuts (image 3C).

Collapse tensioner arm unl the catch lever engages. Install the belt and release spring loaded tensioner
arm by liing the catch.
7.
The tensioner arm plate should now be set 1/4” (6mm) from the inside edge of the drive drum (image 6A).
Set tracking lever in horizontal posion as shown in image 6B. Use a 1/2” wrench to ghten the two bolts
securing the tensioner arm to the main bracket (image 6C).

Spin the belt over a few
revoluons by hand. If the belt
wanders towards the drive
drum, remove belt, loosen the
top bolt of the tensioner arm
(image 6C) and tap the edge of
the platen in small amount on
the le using a mallet (image
8A). If the belt moves towards
the grinder, tap the edge of
platen on the right (image 8B).
Reinstall belt and repeat test.

Vibraon or wobble from the drive drum
Vibraon is oen related to the hardware, installaon, or the grinder itself. It is best to remove the stone
or wheel on the opposite side of the grinder to be sure that is not the source of the problem. Runout at the
edge of the drum of approximately 1/16” is within the standard tolerances for this aachment. This small
amount of runout has virtually no impact on how the aachment operates.
The most common issue we have found is that ghtening the arbor nut can somemes cause the drum to
wobble. You may noce that as the nut is ghtened, runout increases. It may be necessary to use a so face
mallet or hammer and block of wood to take out the bind created by ghtening and true the drum on the
sha. Rotate the drum unl the high spot is idened and strike the drum on the inside edge near the screw
bosses for the cover disc. A substanal strike with a dead blow mallet is required to adjust runout. Light
tapping will generally not have an eect.

When the belt runs evenly on the contact wheel, re-ghten bolt (image 9A). Briey turn grinder on to
perform nal check. Final tracking adjust ments can be done with the tracking lever (image 9B). Pulling
the tracking lever down moves the belt to the le, while moving it up moves the belt to the right.
