Instrumental Measurements
A Measure the gauge depth using the suitable shape.
B Measure the cutter length.
C Measure the chain pitch.
Preparing for Use
ATTENTION 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 m from the floor. The machine can be
bench‑mounted or wall‑mounted.
Mounting the Base Unit – Motor Unit
Securing the Upper Housing / Motor Unit
3
See illustration
. Insert the bolt (I) in the dedicated slot (7) in the motor unit (A)
and through the mounting hole (12) in the support unit (B). Insert the washer (J)
at the front and tighten the locking knob (H).
Note: You may need to depress the upper housing to ensure correct alignment
Bench Mounting
4
See illustration
. Use two (2) appropriate bolts complete with washers
and nuts (not supplied), inserted in the securing holes. Make sure you position
the base unit hanging over the edge of the bench as shown in the detail.
Wall Mounting
Note: Assemble the upper housing / motor unit (A) to the base unit (B) before
mounting to your wall.
5
See illustration
. Use four (4) appropriate bolts complete with washers
(not supplied), inserted in the securing holes.
Assembly
Securing the Operating Handle
See illustration

. Insert the nut (D) into the handle (E). Insert the bolt (C) into
the slot (1). Completely screw the operating handle (E) onto the bolt (C).
Choosing and Installing the Grinding Wheel
WARNING
- Do not force the grinding wheel (K) on the hub (2) and do not alter the centre
hole diameter. Do not use grinding wheels that do not fit perfectly in place.
- Ensure hub (2) and flange (4) are clean and intact.
Choose the Correct Size Grinding Wheel
based on the type of chain to be sharpened (see the chain chart at the end of this
instruction manual).
Testing the Grinding Wheel
7
See illustration
. Hold the grinding wheel (K) up by its centre hole. Knock the
edge of the grinding wheel gently with a non-metallic object. If it makes a dull,
non-metallic noise it means that the wheel could be damaged: Do not use it!
Remove Wheel Guard
See illustration
8
. Remove wheel guard (G) by removing the guard securing
screw (F) from holes (6) using screwdriver (not included).
Remove Flange
9
See illustration
. Using the 5 mm hex spanner (N), remove the grinding
wheel flange screw (3), and the grinding wheel flange (4) from the hub.

Install Grinding Wheel
See illustration
10
. Insert and perfectly centre the grinding wheel (K) in the
dedicated seat on the hub (2).
Reinstall Flange
9
See illustration
. Using the 5 mm hex spanner, insert the flange (4) and
tighten the screw (3).
Make sure you fit the flange as illustrated. If the grinding wheel is fitted with the
flange too tight, it could break during use and put the operator at risk. To avoid such
risk, tighten screw (3) to 62 in-lbs. (7 Nm). If possible, check with a torque wrench.
Reinstall Wheel Guard
See illustration
8
. Reinstall wheel guard (G) with guard securing screw (F) in
holes (6) using screwdriver (not included).
Start‑Up
Plug the power cable into the mains.
Checking the Assembly of the Grinding Wheel
Stand at the side of the grinding wheel.
See illustration
1
. Start the grinder by turning the switch to position "I".
Once started, the lamp lights up to illuminate the sharpening area.
11
See illustration
. 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 to the side of the
grinder, making sure no one else approaches the machine.
Checking the Grinding Wheel Shape
12
See illustration
. With the machine turned off, check the grinding wheel (K)
profile using the measuring template (L); if necessary, dress the wheel torestore
the correct profile.
Grinding Wheel Dressing
Wear personal protective equipment.
See illustration
13
. Start the grinder by turning the switch
to position "I".
Profile the grinding wheel with the dressing brick (O), always working with
extreme caution, holding it with two hands firmly and effectively.
WARNING Contact with the grinding wheel while it spins at high speed
may cause burning and abrasions.
See illustration
12
. Stop the grinder by turning the switch to position "O".
Check if the grinding wheel (K) profile is correct using the template (L). Continue
to dress wheel until profile matches template.
Setting the Sharpening Angles
WARNING
- Wear personal protective equipment when sharpening.
- All adjustments must be made with the motor switched off
and the grinding wheel completely stopped.
- In the case of accidental impact or collision of the grinding wheel during the
sharpening process, follow the instructions given in the "Choosing and installing
the grinding wheel – Warnings" section.
- Clean the chain before sharpening it.
- To avoid overloading the motor excessively and to avoid damaging the chain
cutters, grind minimum quantities of material and do not stop along the same
cutter as this could burn the cutting edge.
- Do not use cooling liquids during the sharpening process.
WARNING Grinding creates sparks which could ignite flammable materials. Do
not operate grinder in presence of flammable materials or explosive atmospheres.
