Multitool PO8CW Manual

WARNING:

To avoid mistakes that could cause injury, do not use the Multitool until 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 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
Belt grinding or finishing has many advantages over the use of conventional grinding
wheels. It is possible to remove material up to 5 times faster than the equivalent grade of
grinding wheel with far less heat. The electrostatic process used in the manufacture 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 cutting. The flexing of the belt has a self cleaning
action and also it does not overheat, making it more suitable to any application where heat
could damage the work, for example, grinding leather, plastics, tool sharpening etc

OPERATING INSTRUCTIONS

BELT CHANGING

To remove the belt simply push down on the underside of belt to compress the tensioner assembly.
The Catch automatically holds slide in retracted position. When refitting the belt simply release
the Catch (Fig 3: O). Always make sure belt lap faces the correct direction.
( see diagram left).

BELT TRACKING

Always ensure the belt entirely covers the rubber contact wheel. Adjustment is made when running
or when belt is rotated by hand. To adjust left, move tracking lever down. To adjust right, move
lever up. If tracking lever is constantly set in up or down position refer to (Figs 5 & 6: N) of fitting
instructions on reverse side.

PLATEN GRINDING (HORIZONTAL OR VERTICAL)

It is important that the Platen (Fig 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 starting. If the platen is not often
used it is better to set a little 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 the drive pulley and raise platen so
that it just touches under side of the belt. Work of any length can be surfaced on the platen, for
example the sawn edges of wood from short pieces up to lengths of several metres. Never grind or
sand on platen unless you are sure belt lap is facing in correct position See diagram left).

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 Mitre 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 operation, making perfect joints possible. A rubber cleaning
stick should be used regularly to prevent a 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, e.g. Lacquer
thinner, acetone (nail polish remover). 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 polish suitable to chrome plate in only two 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. Belt grades of 180 to 400 are
recommended because of the rapid cutting action.
