lightly with a non-metal object (for example, a screwdriver handle). If it is in good conditions it will produce a metallic sound. A dull sound indicates that the
grinding wheel is cracked or broken; if this is the case, do not use the grinding wheel and utilise one with the above specification.
b) Only use grinding wheels as mentioned at point 1) Specification. Never force a grinding wheel onto the machine or change the diameter of the mounting
hole.
c) Installing a grinding wheel with the flange too tight could result in breakage or disintegration during operation. To avoid this risk, tighten the screw manually
and with care. Use exclusively clean, flat flanges to fit grinding wheel.
d) Once the grinding wheel is mounted, refit the grinding wheel guard before switching on the machine.
e) Always test the grinding wheel for at least one minute at operating speed before carrying out grinding. During this operation, keep away from the wheel and
make sure no one else is standing in line with wheel rotation trajectory.
f) If the grinding wheel is found to vibrate/oscillate when starting up or operating the machine, stop it immediately cutting the power off. Check that the grinding
wheel is fitted correctly and that the grinding wheel is not damaged. Before grinding again repeat the above test.
g) Attention: never try to stop the grinding wheel with your hand, even if you wear safety gloves. Touching the grinding wheel while it is turning at high speed
can cause burns and abrasions. Always keep at safety distance.
5) RESIDUAL RISK
a) Place and store the grinder in a dry place, and avoid contact with the ground. Do not expose it to rain; do not use it in places where the air can be impreg-
nated with flammable or explosive gas or liquid.
b) Do not wear bracelets, other jewellery or loose-fitting clothing liable to come into contact with the grinding wheel and grinding area.
c) Do not use extension cables that are defective, not up to safety norms, not in good conditions & not good for use.
d) During grinding wheel and motor operating test (See 4 - d), make sure the machine stops when the switch is pressed in O position. If this does not happen
contact your dealer or authorised service centre.
e) For greater sensitivity of touch, it is not obligatory to wear gloves. To avoid the risk of cutting yourself, move the chain by gripping it correctly on the side
rivet, without touching cutting parts.
f) The machine has been designed exclusively to sharpen saw chains for chainsaws and electric chainsaws. Any improper use is forbidden, do not use tools
other than grinding wheels (DO NOT use knives, saw bands, millers, etc.), do not grind and/or cut other objects.
g) Do not use the machine when you are tired.
h) The machine must not be used at different voltages from the ones specified on the sticker on the machine.
i) Contact your dealer for further explanations, for repair and/or replacement requirements.
6) TRANSPORT
The machine is supplied in a recyclable cardboard box. The box must be handled with care and must not be knocked while being moved.
7) INSTALLATION
The machine is supplied complete and assembled. The following are supplied separately: 3 grinding wheels of different thickness (3.0 - 1/8"; 4.5 mm - 3/16";
6.0 mm - 1/4"), grinding wheel dresser, setscrew wrench for fitting /removing the grinding wheel retention flange, shim to be inserted in the grinding wheel
housing before fitting the 3.0 mm - 1/8" grinding wheel. Make sure the bench on which the machine is to be fitted has all the features mentioned at points 3
(SAFETY) and 5 (OTHER SAFETY NORMS). After stop-regulating the two notches underneath the base (photo 2), fasten the grinder to the bench using two bolts
and the two nuts (not provided) (photo 3). Make sure the fitting is secure before operating.
a) Make sure (table A) that the right grinding wheel is used for the type of chain to be ground. Remove the grinding wheel cover using a screwdriver (photo
4) and then secure the grinding wheel according to the instructions in chapter 4 "WARNINGS ABOUT THE GRINDING WHEEL". Lock the grinding wheel
in position with the flange using the setscrew wrench provided (photo 5). Important: for perfect grinding (see chapter 9), whenever a 3mm (1/8") grinding
wheel is used, it is best to fit the shim before the grinding wheel.
b) Replace the grinding wheel cover and secure using the two screws (photo 4)
To select the right grinding wheel, see diagram A.
8) MACHINE ADJUSTMENT (All adjustments must be made with the machine turned off and the power plug disconnected)
a) Clean the chain before grinding (wash it with petrol or thinner)
b) Lift up the chain stop (Part nr. 1300) and secure the chain on the vice (photo 6). Position the tooth where grinding is to start against the newly lowered chain
stop; by means of the special screw, move the chain stop to the right or left so it rests correctly against the tooth (photo7). Unscrew the knob under the vice and
position this at the angle required (read it on the scale) for the type of chain to be ground (the angle must be the same as the tooth grinding angle. In case of
uncertainty, find this angle in the manuals provided by the chain manufacturers). Secure the vice inclination screwing the lower knob (photo 8). The Marxx
grinders feature automatic fastening of the chain in the vice. To ensure the chain is secured in the centre of the vice jaws, these must be adjusted according
to the chain thickness. This operation can be performed by means of the lever located underneath the arm (photo 9), which regulates the eccentric located on
the side of the outer jaw. Coincide the thickness of the chain shown on the eccentric with the centre of the jaw (if you do not know the chain thickness, find
this in the manuals provided by the manufacturers)
c) Adjust the tilt angle of the head so this coincides with the upper cutting angle of the chain to be ground (in most cases, this is 60°. This angle can be found in
the manuals provided by the chain manufacturers). To make this adjustment, unscrew the knob located in the rear section, turn the head and then secure this
again by tightening the knob (photo 10). To grind the right teeth of a chain, the head must always be on the right side (with respect to the operator) of the
machine. To grind the left teeth, this can be in the same position as that for grinding the series of right teeth or on the left of the operator (in this connection,
see chapter 9 Grinding).
d) Always with the motor switched off, lower the arm until the grinding wheel skims the chain tooth, secure the depth stop by tightening or loosening the locknut
(photo 11). During grinding do not touch the drive link and the tie strap (for further information refer to the chain maintenance manual, provided by chain
manufacturers)!.
e) Depending on the quantity of material to be removed, adjust (forwards or backwards) the screw positioned on the connecting rod of the chain stop and which
moves the rear stop point of the tooth backwards or forwards (photo 12). Once the required position has been reached tighten the locknut.
f) If the chain has been ground several times, the depth stops in the tooth link could be too high and prevent the tooth from cutting correctly. These can be
returned to correct measurement using the 6.0 mm - 1/4" grinding wheel. To fit this wheel, see the instructions provided on grinding wheel fitting (chapter 7
Installation). Lower the depth stop after making all the adjustments as shown in this chapter, but moving the head of the grinder (photo 10) to vertical position
(read graduated scale 0°).
Once all adjustments have been made, the machine is ready to grind the chain
