Clamp the tool in the appropriate jig.
Adjust the support arm (G, Fig 9) and
change the tool clamping position to
get to the wanted grinding angle.
Fig 9
Use the angle measuring device (S) to
inspect the angle in relation to the
stone wheel.
Note:
The stone diameter needs to be set on
the scale (X) to get correct angle
reading.
7.2 Torque adjustment
During heavy machining the friction
drive may slip.
Therefore a torque adjustment has
been installed to the machine.
Turn the torque adjust knob (D, Fig 1)
clockwise to add more pressure to the
friction drive.
When no added torque is required or
when the machine is not in use,
release the pressure to avoid
permanent deformation of the friction
drive rubber (O).
7.3 Changing the stone wheel
If the stone wheel (C) is worn down to
a diameter of approximately 150mm it
needs to be replaced.
Disconnect from power source,
unplug!
Loosen the Nut (M) and remove the
old stone wheel.
Fig 10
The new stone wheel has to meet the
technical specification.
Check abrasive wheel for flaws (e.g.
cracks) before installation. Do not use
faulty wheels.
Install the new stone wheel
(C, Fig 10….Jet Article No.: JSSG8-503).
Place a washer (L) on each sides of the
stone wheel and tighten the nut (M).
7.4 Changing the honing wheel
Disconnect from power source,
unplug!
Loosen the lock knob (N) and remove
the worn honing wheel.
Fig 11
Install the new leather honing wheel
(A, Fig 11 Jet Article No.: JSSG8-509)
Pay attention that the 3 drive pins
engage with the friction drive wheel
(O).
If the leather strop wheel seems to
wobble, please try rotating it to the
next pin location.
Tighten the lock knob (N)
8. Maintenance and inspection
Make all adjustments or
machine maintenance
with the machine
unplugged from the
power source.
Repair and maintenance work on the
electrical system may only be carried
out by a qualified electrician.
All protective and safety devices must
be re-attached immediately after
completed cleaning, repair and
maintenance work.
Defective safety devices must be
replaced immediately.
Cleaning:
Regularly change the water in the
water tank.
Regularly clean the machine housing
with a soft cloth preferably after each
use.
If the dirt does not come off use a soft
cloth moistened with soapy water.
Never use solvents such as petrol,
alcohol, ammoniac water, etc. These
solvents may damage the plastic parts.
Inspecting the brushes:
Disconnect from power source,
unplug!
Inspect the motor brushes after 300
hours of use.
If the brushes are worn to 6 mm
replace them.
