FITTING THE GRINDING WHEEL
1 - Make sure that the grinding wheel is in perfect condition.
Hang the wheel by the central hole and tap it lightly with a metal object on the side near the perimeter. You should hear a metallic
sound. A dull sound means that the wheel is cracked or broken, and
must not be used.
2 - Consult the enclosed table (Fig. 7) to choose the appropriate grinding wheel (8) for the type of chain to be ground, and fit the wheel
securely. Attach screen (12) using the two screws provided and guard (15) after the lever (16) has been fitted.
CHECKING THE GRINDING WHEEL
1 - With the machine off, check the profile of the wheel using the special template (Fig. 5) and, if necessary, retouch the wheel using the
dressing stone provided.
Always wear protective eyewear.
2 - Put the switch in the “O” position, and connect the plug correctly to the electrical outlet.
3 - Stand beside the wheel and examine it to ensure that it does not oscillate either laterally or transversally.
Replace the wheel if
necessary
.
GRINDING
1 - We recommend that you clean the chain before grinding it.
2 - Place the chain on the guides (11) with the depth gauge (13) on the right.
3 - Rotate the chain support (5) by 30-35° on the graduated scale (4) according to the type of chain. Tighten the flywheel (6).
4 - Position the cutter in relation to the wheel using the register (9), always starting from the most worn cutter identified using the
template.
5 - Adjust the grinding depth using the screw (10).
6 - Clamp the chain lightly using the knob (7).
7 -
Put on protective eyewear.
8 - Grind all the cutters of the same type before turning the chain support (5) by 30-35° from the opposite side.
Make this rotation with the grinding wheel stopped.
9 -
To avoid overloading the motor and so as not to damage the chain, remove the minimum quantity of material necessary
and do not stay too long on the same tooth.
10 - For very worn chains, adjust the stop (13) using the knob (14) to prevent the wheel from nicking the stop.
11 - After grinding, if the right cutters are shorter, tighten the screw (3) accordingly. If the right cutters are longer, loosen the screw (3)
accordingly.
12 - Rotate the grinding wheel so that the grinding burr is turned toward the outside of the cutters.
NOTE: When the job is finished, switch the grinder off by putting the switch in the “O” position.
WARNING: If the grinder does not switch on when the switch is positioned on “I”, disconnect the power supply cable immediately.
GRINDING CHAINS WITH STRAIGHT CUTTERS
1 - With the thickest wheel fitted, fix the arm from 90° to 45° as read on the plate (1).
2 - Depending on the cutter to be ground, rotate the chain support by 40° to the right or left as read on the scale (4).
3 - If the right cutters prove to be longer than the left cutters after grinding, make adjustments by slightly turning the screw (3).
GRINDING THE DEPTH GAUGES
1 - Fit the thickest grinding wheel tilted from 90° to 60° and shape it using the dressing stone as needed. Check the profile using the
angles of the template.
2 - Set the chain support (5) at zero degrees according to the plate (4).
3 - Position the depth gauge in relation to the grinding wheel using adjustment screws (9) and (10).
IMPORTANT NOTES
- If the grinding wheel is accidentally struck or bumped, repeat the instructions in point 1 of the section “FITTING THE
GRINDING WHEEL”.
- Replace the grinding wheel when its minimum diameter has reached approximately 70 mm (2.8”).
- Do not use cooling liquids while grinding.
- The warranty will be void if:
a. the grinder has been tampered with;
b. the grinder has not been used according to this instruction manual;
c. non-original and/or unauthorized parts, tools, or grinding wheels have been fitted on the machine;
d. the grinder has been connected to a voltage other than the one stated on the serial number plate.

Grounding methods
2 - Fasten the grinder to a bench or to
the wall using two screws of
appropriate length (fig. 1A-B-C).
For correct bench positioning,
make use of the notch on the base
(fig. 1D).
