1 Transport & handling

1.1 Transport

PSD 5 Industrial belt grinder and others are delivered on a pallet packed in protective
wrapping.

1.2 Handling

The machines can easily be transported on the pallet on which they are delivered. If the
machine is delivered on a pedestal you must insure that the pedestal is secured to the
pallet.

1.3 Placing

Mounting of the machine must take place on a firm level ground. It must be fastened to the
ground by means of the four fittings which are used to fasten the machine to the pallet. It is
provided with no-volt release protection switch and connected for the wanted voltage. The
electrical connection must be performed by an authorized electrician, and it is important to
control that the motor (and the exhaust unit) have the correct direction or rotation (please
see the arrow on the motor).

Fig.: 1.1

Before use you must control that the outer cover (A) (se fig.: 1.1) is solidly mounted on the
inner cover. The outer cover must stay mounted during use and should only be dismounted
during change of grinding wheel. The grinding wheel (B) must be able to rotate freely
without being loose. The tool rest (C) must be adjusted to a distance of approximately 2 mm
from the grinding wheel.
The eye shield (D) must be clean and adjusted into the right position and the spark arrester
(E) must also be adjusted to a distance of approximately 5 mm from the grinding wheel and
slightly fastened.

The first time you start the belt grinder please let it run at max speed without using it for 5
minutes. Make sure to stay in a safe distance during the machine start-up.

2 Directions for use

2.1 Operation

After adjustment and connection the machine is ready for use. The grinding kan take place
by the contact wheel (E) or on the surface grinding table by opening the cover (H). When
you start grinding please start by letting the material touch the grinding wheel lightly and
thereby avoid pressuring the grinding wheel to prolonge the lifetime of it. The lifetime of a
grinding belt is also prolonged if you start with a light pressure. Please make sure not to
overload the motor. Let it run at max speed before start grinding. Grind at max speed and if
possible have the material tightened in clamps as it is safer than holding the material in
your hands. Avoid grinding on the side of the grinding wheel unless you are using a cup
wheel. Do not stop the grinding wheel by pushing any material against it but let it stop by
itself. It is very important to keep the working area well lighted.

2.2 Safety rules for stationary power tools.

Follow them to achieve best results and full benefit from your new machine.

The good craftsman respects
the tools with which he works.
He knows they represent years
of constantly improved design.
He also knows that they are
dangerous if misused.
The safety rules are based on
approved practices in industrial
and home shops.

1. Know your power
tool. Read the

owner’s manual

carefully. Learn its
applications and
limitations, as well
as the specific
potential hazards
peculiar to this tool.

2. Keep guard in place
and in working order.

3. Ground all tools. If tool is equipped with three­prong plug, it should be plugged into a three-hole
electrical receptacle. If an adapter is used to
accomodate a two­prong receptacle, the
adapter wire must be
attached to a known
ground. Never
remove the third
prong.

4. Remove adjusting keys
and wrenches. Form
habit of checking to see
that keys and adjusting
wrenches is removed
before turning it on.

5. Cluttered areas and benches invite accidents.

6. Avoid dangerous

environment. Don’t use

power tools in damp or wet
locations or expose them to
rain. Keep your work area
well lighted.

6. Keep children away.
All visitors should be
kept in a safe distance
from work area.

5

8. Make workshop
kidproof with
padlocks, master
switches, or by
removing starter keys.

9. Don’t force tool. It will
do the job better and be
safer at the rate for
which it was designed.
.

10. Use right tool.

Don’t force tool or

attachment to do
a job it was not
designed for.

11. Wear proper apparel. Wear no loose clothing,
gloves, neckties, rings,
bracelets, or other
jewelry which may get
caught in moving parts.
Non-slip footwear is
recommended. Wear
protective hair covering
to contain long hair.

12. Always use safety
glasses. Also use face or
dust mask if cutting
operation is dusty.
Everyday eyeglasses only
have impact resistant
lenses. They are NOT
safety glasses.

13. Secure works. Use
clamps or vise to hold

works, when pratical. It’s

safer than using your
hands and it frees both
hands to operate tool.

14. Don’t
overreach.
Keep proper
footing and
balance at
all times.

15. Maintain tools with care. Keep tools sharp and
clean for best and safest
performance. Follow
instructions for lubricating
and changing accessories.

16. Disconnect tools before
servicing and when changing
accessories such as grinding
wheels, polishing mops,
grinding belts, blades, bits,
cutters, etc. Never leave a
running maschine, wait till the
Machine has stopped. If parts
of the machine are out of order
the Machine shold not be used
befour it has been repaired.

17. Reduce the risk of
unintentional starting.
Make sure switch is in off
position before plugging
in.

18. Use recommended accessories. Consult owner’s
manual for recommended accessories. Use of
improper accessories may cause risk of injury to
persons.

19. Never work in a way that can hurt you. Do not
stand in a bent position. Stand straight. Alkohol and
other drugs are not to be taken while working with
the machine.

2.3 Maintenance

Keep the machine in a dry place so the grinding wheels or belts will not risk getting any
damp or rain.
The grinding wheel will often get uneven because of use and therefore we recommend that
you level the grinding wheel off frequently. When the grinding wheel is worn more than 25%
we recommend that you change to a new wheel. An uneven grinding wheel causes
vibrations which with time will damage the bearings in the machine. Damaged tool rests,
eye shields and covers must be replaced to avoid personal damage.

When to change the grinding wheel please dismount the spark arrester (A) (see fig.: 2.1),
then dismount the outer cover (B). The reverse nut (C) and the outer flange is to be
unscrewed, now the outer flange and the grinding wheel can be dismounted. The new
grinding wheel is not allowed to exceed the measures shown on the sign on the machine. It
is also very important that the hole dimension is correct.
The grinding wheels are provided with labels placed around the holes on both sides of the
grinding wheel. If these labels are missing or damaged they must be replaced by new ones
of the same dimension.
The new grinding wheel is to be mounted between the two flanges (D) and the reverse nut
(C) screwed on and fastened. The reverse nut (C) is to be fastened so tightly that it can
hold the grinding wheel tight but on the other hand it is not to be tightened too much as it
can cause unwanted stress in the grinding wheel.

3 Belt Arm

3.1 Assembly and mounting of belt arm

If the grinding machine is mounted with a grinder cover or a deburrer cover these must be
removed completely before mounting the belt arm.

Mount the telescopearm (A) to the cover (B) by using the fitting for the telescope arm (C)
and mounting the cover (B) by putting a screw through the side plate into the holder for the
telescopearm (D). The topwheel (E) must be inside the cover (B).

Fig.: 3.1

The fitting for the telescopearm (C) is not alloved to be fastened harder than it is
still possible to adjust the direction of the grinding belt.

The belt arm can be tilted to the wanted inclination. After this the holder for the
telescopearm (D) is fastened by tightening the two screws placed in the ring on the
holder. The flanges, contact wheel and the reserve nut are now put in (pls. see the
drawing of belt arm for order). Please make sure that the top wheel (E) and the
contact wheel run parallelly. The position of the contact wheel can be adjusted with
the distance rings attached.

The topwheel (E) can be loosened and adjusted so that it fits the wanted grinding
belt lenght. The same way you can tighten the grinding belt.

3.2 Changing of grinding belt

When the grinding belt is worn out it must be replaced which is done the following
way: The top plate (A) (se fig.: 3.2) on the cover is opened and the handle (B) is
pulled down. This way the pressure on the grinding belt will be lowered (C), so that
it can be dismounted and a new grinding belt can be mounted in reverse order.
Please control that the arrows on the back of the grinding belt run in the same
direction as they point. When the new grinding belt is mounted it is necessary to
adjust by the handle (D) for parallel running. The belt is loosened so that the
telescopearm (E) and top wheel (F) can be turned with until the grinding belt runs
straightly on the contactwheel. After this the handle is fastened (D).

It is only allowed to do this adjustment by pulling the grinding belt with the
hands and NOT with power on the machine.

Fig.: 3.2

There are many kinds of grinding belts so therefore it is very important to choose
the right type of belt. There are many things to consider before choosing the belt:
material to be grinded - grit size - belt material - glue.
In connection to this we can tell you that there are different kinds of contact wheels
with various softnes and shapes for different purposes.
