Precision Tooling Speed Sharp Star Manual De Instrucciones página 8

- Switch: the machine features a safety switch with release coil. In the case of a
sudden power failure, the switch trips automatically and disconnects the machine
from the mains. The machine will not start even if the power supply is suddenly
restored. You need to reset the switch to start the machine again.
- Safety button: this is used to block the arm in the completely raised position.
When the button is released, the arm is blocked. This condition is required when ad-
justing the sharpening angles, when replacing and dressing the grinding wheel.
When the button is pressed, the arm is free to move. This condition is required
during the sharpening process.
If the arm is released suddenly when the machine is in use, the button trips and
blocks the arm in the raised position.

13. TeSTIng THe grIndIng wHeel
Hold the grinding wheel up by its central hole. Knock the edge of the grinding wheel
(fig.3) gently with a metal object. If it makes a numb non-metallic noise it means that
the wheel could be damaged: do noT use it!

Do not install the machine at eye level. You are recommended to install it at a height
of no more than 1.2-1.3 meters off the floor.
The machine can be bench mounted or wall mounted.
14.1 bencH mounTIng
- securing the base unit (fig.4): use 2 M8 screws complete with washers and nuts
(material not supplied), inserted in the securing holes F4. Make sure you position
the base unit on the bench as illustrated in the detail.
- Fitting the arm (fig.5): to secure the arm-motor unit to the base unit, insert the V5
screw in the dedicated hole F5. Insert the R5 washer at the back and tighten the
knob M5.
14.2 wall mounTIng
- securing the base unit (fig.6): use two dowels with relative screws complete with
washers (material not supplied), inserted in the securing holes F6.
- Fitting the arm (fig.5): to secure the arm-motor unit to the base unit, insert the V5
screw in the dedicated hole F5. Insert the R5 washer at the back and tighten the
nut D5.

16. cHaIn IdenTIfIcaTIon
- Before you start to sharpen, you need to know the type of chain and the relative
adjustment angles. These characteristics are written in the owner's manual of the
chain saw on which the chain is fitted or on the chain pack.
- The chain identification code is usually written on the driving link.
- You can also identify the chain using a template or gauge.
- Consult the CHAIN CHART at the end of this manual.
The columns in this chart provide the following information:
÷ 2
a Chain pitch
b Gauge
c Top sharpening angle (vise rotation)
d Cutting angle (arm rotation)
e Down angle (vise inclination)
f Gauge depth
g Grinding wheel thickness
H Grinding wheel code
I Oregon chain codes
l Windsor chain codes
m SARP chain codes
16.1 InSTrumenTal meaSuremenTS (fIg.13)
a - Measure the gauge depth using the suitable shape.
b - Put the template on this side and measure the chain PITCH.
c - Put the template on this side to measure the cutter length.
d - The driving link width is measured using a suitable instrument (i.e. gauge).
17. grIndIng wHeel warnIngS
- Use a grinding wheel suitable for the type of chain to be sharpened; consult the
chain chart at the end of the manual.
- Do not force the grinding wheel on the hub and do not alter the centering hole
diameter. Do not use grinding wheels that do not fit perfectly in place.
- Use exclusively clean and perfect intact hub and flange to fit the grinding wheel.
- Make sure the outside diameters of the hub and flange are identical.
18. fITTIng THe grIndIng wHeel
- Loosen the screw V10 and turn the guard P10 (fig.8).
- Remove the screw V8 and the flange F8 on the hub (fig.8).
- Choose the grinding wheel based on the type of chain to be sharpened (column H
in chain chart).
- Insert and perfectly center the grinding wheel in the dedicated seat on the hub
(fig.14-15).
- Insert the flange F8 and tighten the screw V8 (fig.14).
Make sure you fit the flange as illustrated in fig.15-16.
If the grinding wheel is fitted with the flanges too tight, it could break during
use and put the operator at risk. To avoid such risk, tighten screw M6x25 to
7 nm (if possible, check with dynamometric spanner).
- Close the guard again P10 and tighten the relative screw V10. Do not screw the
screw too tight during this job to avoid cracking the guards.
19. cHeckIng THe aSSembly of THe grIndIng wHeel
- Stand at the side of the grinding wheel, start the grinder and visually make sure
the grinding wheel does not oscillate sideways or crosswise, consequently causing
abnormal vibrations.
- If this should be the case, stop the machine immediately and check if the grinding
wheel has been fitted correctly. If necessary, replace the grinding wheel with another
original one.
Always check a freshly fitted grinding wheel at working speed for at least one
minute before you start grinding, standing at a safe distance and making sure
nobody else approaches the machine.
