Multitool 362 Plus User manual

WARNING:
Read, understand and follow all instructions before operating the
Multitool:
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 cutting tool. Extra care should
be exercised when using coarse grit belts because of their
rapid cutting action.
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
supporting surface to stop it from tipping over or moving
when in use.
5. DO NOT MOUNT the attachment protruding into walkways.
6. KEEP WORK AREA CLEAN. Cluttered areas and benches
invite accidents.
7. ALWAYS WEAR A DUST MASK to prevent dust
inhalation when adequate ventilation or extraction is not
available.
8. DO NOT WEAR LOOSE CLOTHING which may become
entangled in the machine. Wear protective 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 position, resulting 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 facing the correct direction. Belts and lap joints must be
fitted facing the correct direction. See sketch below.

Unscrew the nut and remove the
washer and Drive Pulley (Fig 2,B). Leave the
ange in place. (Fig 3)
Using the 5/16” bolts & washer (Fig 1, 8)
aach the Tensioner Assembly (Fig 1, 3) to
the Main Bracket (Fig1 /A). Tighten rmly
so that it will allow for some movement, as
it may need to be adjusted when tracking.
(Refer Fig 7 text)
Return the Drive Pulley (Fig 1/B) to the sha next to the ange
followed by the washer and ghten the nut.
Note: The 6” motor (plus) has a 1/2” sha size with a 1/2”
metal bush inserted in the Drive Pulley. When removing the
Drive Pulley from the motor if the bush becomes detached
reinsert back into the Drive Pulley before reassembly.
The Cam Plate of the Tensioner
Assembly must now be set at 6mm
(1/4”) clear of the inside edge of the
Drive Pulley.
Set the tracking lever (above) to mid or
horizontal posion. Fit the belt and
release the spring loaded contact wheel
by liing the catch. (Fig.3)

Catch
Cam Plate
Pull the belt over a few revoluons by hand. If the belt wanders towards the
drive pulley (Fig 1. B.) tap the top of the cam plate in small amounts towards the
drive pulley. If the belt moves towards the grinder tap the top of the cam plate
towards the grinder.
When the belt runs evenly on the contact wheel ghten the two bolts holding the
cam plate. Final tracking adjustments can be done with the tracking lever. Pulling
the tracking lever down moves the belt to the le, up moves the belt to the right.
Fit the cover plate using counter sunk screws provided. Clean the face of the
cover disc with a solvent (not a household cleaner) and t adhesive backed
abrasive disc provided.

BELT CHANGING
To remove the belt simply push down on the underside of belt to compress the tensioner assembly. Catch automatically holds slide in retracted position. When refitting the
belt simply release the catch (fig 3) Always make sure the belt lap faces the correct direction. (diagram reverse side)
DISC GRINDING
Whenever possible remove the belt when using the disc facility. The disc grinding facility is a very useful and versatile part of the attachment. It is very useful for dressing
small castings and components, patterns, models etc., often eliminating costly machining. Tool and cutter sharpening is a simple task and there is less chance of burning
edges. With the addition of the table, lengths and angles are easy to adjust. A rubber cleaning stick should be used regularly to prevent the build up of wood resin. Three
options are available in abrasive discs. 1. Self-Adhesive. 2. Fur backed – which must be used with an optional hook and loop backing pad. 3. Plain paper or cloth backed
disc which must be attached with a contact adhesive. When changing a disc pad remove any remaining adhesive with a solvent eg acetone– Do not use household
cleaners.
CONTACT WHEEL GRINDING, POLISHING AND SANDING
Using the front contact wheel avails the user of material removal many times faster than a conventional grinding wheel. The unique smooth cutting action is cooler, faster
and safer than conventional grinding methods. A good example of one of the many uses is the smoothing of welds and casting blemishes prior to plating. Using the
extremely fast and easy belt change, it is possible to go from a rough weld finish to a flat smooth polished finish suitable to chrome plate in only three belt changes. e.g.
Remove rough weld with 40, 60 or 80 grit belt. Remove grinding marks – 240 grit belt. Change ground finish to smooth, brushed finish for plating – Scotchbrite super
fine. 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 stick helps prevent clogging on wood use.
FREE STRAPPING
Free strapping 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 operations. It is done on the underneath side of the belt opposite the platen. It is ideally suited to narrow belt widths as small as ½” (13mm). Belt grades of
180 to 400 are recommended because of the rapid cutting action of narrow belts.
