1.0 Transport & Handling
1.1 Transport
The Silverstar belt grinding machine is packed in protective wrapping and delivered
on a pallet with the following measures: 120 x 80 x 120 cm
1.2 Handling
The machine can easily be transported on the pallet on which it is delivered.
1.3 Placing
Mounting of the belt grinder must take place on a firm and level ground. The machine
must be fastened to the ground by means of the four fittings which are used to
fasten the belt grinder to the pallet.
The machine is provided with no-volt release protection switch and connected for
the wanted voltage (V). The electrical connection must be performed by an
authorized electrician, and it is important to control that the motor (and ventilator)
has the correct direction or rotation (please see the arrow on the motor).
Eye shields, suction hose and perhaps dust bag must be mounted before use. The
clamps for mounting the suction hose are placed in the dust bag. The eye shields (A)
must be mounted into the eye shield fitting (see fig.: 1.1).
Fig.: 1.1
The tool rest (B) must be mounted at minimum 2 mm from the belt, and the handle (C)
must be fastened. Turn the contact wheel by your hand and adjust the belt by means
of the handle (D) until it runs just on the contact wheel (E). It must be controlled that
the spark box (F) is properly fastened. The wanted working height is adjusted by
bolt/locknut (G).

2.0 Directions
2.1 Operation
After adjustment and connection, the belt grinding machine is ready for use. The
grinding can take place by the contact wheel (E) or on the surface grinding table by
opening the cover (H). The lifetime of a new belt is prolonged if the grinding starts
with a light pressure.
Please note these safety rules: the machine is designated for use only with non-
spark materials, such as Aluminium-bronze- yellow metal.
Never use steel or any type of metal that when grinded will dispose sparks.
2.2 Security
The existing safety rules must be kept in order to avoid personal or material injury
when working with the belt grinder.
A. User
Do not wear loose clothing, gloves, rings, bracelets, or other jewellery to get caught
in moving parts. Nonslip footwear is recommended. Wear protective hair covering to
contain long hair.
Always wear eye protection and face or dust mask if the operation is dusty. Ordinary
glasses cannot replace eye protection.
Don´t overreach. Keep proper footing and balance at all times.
Never leave tool running unattended. Turn power off. Don´t leave tool until it comes
to a complete stop.
Don´t operate tool while under influence of drugs, alcohol, or any medication.
B. Use of Machine

designed.
Use recommended accessories. Consult the owner´s manual for recommended
accessories. The use of improper accessories may cause hazards.
C. Adjustment
Make all adjustments with the power off. In order to obtain the machine precision and
correct ways of adjustment while assembling, the user should read the detailed
instruction in this manual.

cleaning. Empty or change the dust bag as required. The contact wheel should be
replaced when the edges have been worn round or the tyre has been damaged. The
graphite pad on the surface grinding table is changed as required.
Fig.: 2.1
When changing the belt it is released by turning the handle (I) in anti-clock-wise
direction (see fig.: 2.1), the cover (J) is opened and the worn-down belt (K) is removed
by driving the belt against the direction of rotation, and the belt is removed from the
machine by the drive wheel. The new belt is fitted. It must be checked that the
direction of the arrows on the back side of the belt correpsond to the direction of
rotation. The handle (I) is turned clockwise until grinding belt is tightened. Check for
alignment by turning the grinding belt by hand and adjust with handle (D)
