OPERATING INSTRUCTIONS
WARNING:
To avoid mistakes that could cause injury, do not use the Multool unl you
have read and understood the following:
1. ALWAYS WEAR EYE PROTECTION. A full-face visor is preferred. Any Belt/Disc
Grinder can throw foreign objects into the eyes.
2. AVOID EYE 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 firmly 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 fly 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 fied facing the correct
direcon. See sketch below.
Belt grinding or finishing has many advantages over the use of convenonal grinding wheels. It is
possible to remove material up to 5 mes faster than the equivalent grade of grinding wheel with
far less heat. The electrostac process used in the manufacturing of an abrasive belt ensures that
the sharp side of each piece of grit is facing outwards on the belt thus giving cleaner, smoother
and faster cung. The flexing of the belt has a self-cleaning and cooling acon, making it more
suitable to any applicaon where heat could damage the work such as grinding leather, plascs,
tool sharpening etc.
MACHINE SPECIFICATIONS
MULTITOOL 364
Belt size 36” x 4” - Disc size 7” - Contact Wheel 3½” diameter. Fits most 6” or 8” bench grinders
with minimum 1/2 H.P. and sha sizes of 1/2” or 5/8”.
BELT APPLICATIONS
To remove the belt simply push down on the underside of belt to compress the tensioner assembly.
Catch automacally holds the slide in retracted posion. When refing the belt simply release the
catch (Step 3:O). Always make sure belt lap faces the correct direcon (see diagram le).
BELT CHANGING
Always ensure the belt enrely covers the rubber contact wheel. Adjustment is made when
running or when belt is rotated by hand. To adjust le, move tracking lever down. To adjust right,
move lever up. If tracking lever is constantly set in up or down posion, refer to Steps 3 & 4 of fing
instrucons on reverse side.
BELT TRACKING
It is important that the Platen (Step 4: P) is not set too high. If belt is deflected and rides up over the
platen it creates an undue strain on the grinder, especially when starng. If platen is not oen used,
it is beer to set a lile clear of 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 drum and raise platen so that it just
touches under side of belt. Work of any length can be surfaced on the platen, for example the saw
edges of wood from short pieces up to lengths of several feet. Never grind or sand on platen unless
you are sure belt lap is facing in correct posion.
(See diagram at le)
PLATEN GRINDING (HORIZONTAL OR VERTICAL)
Whenever possible remove the belt when using the grinding disc. The disc grinder is a very versale
part of the aachment that can be used for dressing small casngs and components, paerns,
models, etc. oen eliminang costly machining. Tool and cuer sharpening is a simple task and
there is less chance of burning edges. With the addion of the table, lengths and angles are easy to
adjust. Dressing end grain, flat and square, has always been a difficult task but now it is a simple and
quick operaon, making perfect joints possible. A rubber cleaning sck should be used regularly to
prevent build up wood resin. When changing a disc pad remove any remaining adhesive with a
solvent, e.g. Lacquer thinner, acetone (nail polish remover). Do not use household cleaners.
DISC GRINDING
Using the front contact wheel removes material many mes faster than a convenonal grinding
wheel. The unique smooth cung acon is cooler, faster, and safer than convenonal grinding
methods. A good example of one of the many uses is the smoothing of welds and casng blemishes
prior to plang. Using the extremely fast and easy belt change, it is possible to go from a rough
weld finish to a flat, smooth polish suitable to chrome plate in only two belt changes. e.g. Remove
rough weld with 40 or 80 grit belt. Remove grinding marks with 240 grit belt. Change ground finish
to smooth, brushed finish for plang using Scotchbrite super fine or Trizact belts. Wood shaping
and finishing can be done in a similar manner, but belts should always be kept exclusively for wood,
especially in the finer grades. A rubber belt cleaning sck helps prevent clogging on wood use.
CONTACT WHEEL GRINDING, POLISHING, AND SANDING
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. It is done on the underneath side of the belt opposite the platen. Belt grits of 180 to 400 are
recommended because of the rapid cung acon.

Use 13mm (13) or 16mm (11) diameter washer under the sha nut and ghten. If
drive drum does not run true, use rubber or leather hammer to tap on the inside
edge of rim where run-out may occur.
NOTE: A poor quality nut may prevent drum from running true. If this is the case,
replace factory nut with high quality alternave.
Step 6
Tensioner arm cam plate (M) must now be set 1/4” (6mm) from the inside edge
of the drive drum (Step 4: K). Slots are provided for 8mm bolts (Step 3: J) for this
adjustment. Set tracking lever (N) in mid or horizontal posion. Fit the belt and
release spring loaded contact wheel by liing the catch (Step 3: O).
NOTE: It is not necessary to remove the platen as in Steps 5 and 6. This has been
removed for clarity and instrucon only. There will always be some parts le over
aer fing.
Spin the belt over a few revoluons by hand. If the belt wanders towards the drive
drum (Step 4: K), loosen the top bolt (Step 3: J) and tap the top of the cam plate
(M) in small amount towards the drum. If the belt moves towards the grinder, tap
the top of cam plate (M) towards the grinder. When the belt runs evenly on the
contact wheel, re-ghten bolt (J), turn grinder on to check. Final tracking adjust-
ments can be done with the tracking lever (N). Pulling the tracking lever down
moves belt to the le, up moves the belt to the right. Fit the cover plate using
bolts (4). Clean face of cover disc with a solvent and fit adhesive backed abrasive
disc provided.

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 as shown
above.
NOTE: Some grinders may require the use of addional washers between the
grinder and adaptor plate to clear bolt heads. This may require the use of longer
bolts to get full thread engagement in motor housing. (Step 2: E).
Fit the tensioner arm (H) using 8mm bolts (2) and washers (7) provided into slots
(J). Fit one of the washers (13) that suits 1/2” or (11) suing 5/8” diameter sha
size on the grinder sha. Fit the drive drum (Step 4: K) by sliding over the sha of
the grinder. If there is interference between the adapter plate bolts and drive drum,
add addional washers to gain acceptable clearance. The drive drum (Step 4: K)
comes with a 5/8” bore. There is a nylon bushing (10) provided for 1/2” shas.

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 machine. 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 drum nut can somemes cause the drum to wobble. You may be able to see that the more you ghten the nut, the more the runout
increases. You may need to use a so face mallet or hammer and block of wood to take out the bind created by ghtening and true it up on the sha. Just rotate the drum unl you idenfy the high
spot and strike the drum on the inside edge near the screw bosses for the cover disc. It takes a substanal strike with a dead blow mallet to make a change. Light tapping is generally not going to have
an eect.

Tracking Adjustments
Although, your new Multool should track correctly right out of the box, there’s a chance that some simple adjustments may need to be made so that your Multool will track properly. Aer taking it
out of the box and aempng to use it for the first me, you may noce the belt wandering le or right on the contact wheel. Using the tracking lever on the Multool arm will help track the belt, but
somemes that adjustment isn’t enough. The following steps can be made to help your Multool track properly.
Center the tracking lever on the Multool arm and take o the Drive Drum. Removing the Drive Drum will allow you to gain access to two bolts aaching the Multool cam plate to the 90 degree
mounng bracket that is aached to the grinder motor. Loosen the two bolts that aach the arm, however keep them snug enough so adjustments to the arm can be made. Re-mount the Drive Drum
and install the belt. Spin the belt by hand. If the belt wanders towards the right, tap the top of the cam plate in small amounts towards the right. If the belt moves towards the le, tap the top of cam
plate towards the le. When the belt runs evenly on the contact wheel, re-ghten bolts that aach the multool cam plate to the 90 degree bracket. Turn grinder on to check that it is tracking properly.
Final tracking adjustments can be done with the tracking lever. Note: the belt will always dri toward the high side of the contact wheel.
