OPERATING INSTRUCTIONS
WARNING:
To avoid mistakes that could cause injury, do not use the Multool unl 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 cung tool. Extra care should be exercised when using
coarse grit belts because of their rapid cung acon.
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 supporng surface to
stop it from pping over or moving when in use.
5. DO NOT MOUNT the aachment protruding into walkways.
6. KEEP WORK AREA CLEAN. Cluered areas and benches invite accidents.
7. ALWAYS WEAR A DUST MASK to prevent dust inhalaon when adequate
venlaon or extracon is not available.
8. DO NOT WEAR LOOSE CLOTHING, which may become entangled in the
machine. Wear protecve 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 posion,
resulng 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 poinng the
correct direcon. Belts with lap joints must be fied facing the correct
direcon. See sketch below.
Belt grinding or finishing has many advantages over the use of convenonal 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 electrostac 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 cung. The flexing of the belt has a self-cleaning and cooling acon, making it more
suitable to any applicaon where heat could damage the work such as grinding leather, plascs,
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 automacally holds the slide in retracted posion. When refing the belt simply release the
catch (Step 3:O). Always make sure belt lap faces the correct direcon (see diagram le).
BELT CHANGING
Always ensure the belt enrely 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 posion, refer to Steps 3 & 4 of fing
instrucons 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 starng. If platen is not oen used,
it is beer to set a lile 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 posion.
(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 versale
part of the aachment that can be used for dressing small casngs and components, paerns,
models, etc. oen eliminang costly machining. Tool and cuer sharpening is a simple task and
there is less chance of burning edges. With the addion 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 operaon, making perfect joints possible. A rubber cleaning sck 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 convenonal grinding
wheel. The unique smooth cung acon is cooler, faster, and safer than convenonal grinding
methods. A good example of one of the many uses is the smoothing of welds and casng blemishes
prior to plang. 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 plang 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 sck 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 cung acon.
