Operating the Ultra Mk4
!
WARNING:
Before adjusting the unit, make sure the machine is switched ‘
OFF
’ at the
power supply to prevent unintended starting.
1. Clean and inspect the chain before sharpening. Look for the most worn-out cutting tooth, this
is important in order to sharpen all the other teeth to the same depth!
2. Position the chain between the clamping
plates of the guide vise. Fold down the
chain stop, pulling on the chain, slide the
chain up against the chain stop. The chain
stop prevents the chain moving and allows
fine tuning of the grinding wheel position
on the chain.
3. Check the various setup angles are set
according to the chain specification.
4. As the wheel is brought into contact with
the chain the clamp bars automatically grip
the chain.
6. Bring the grinding wheel down without the
unit running to check position and angle.
Once satisfied, after raising the grinding
wheel, switch on the Ultra MK4 and then
sharpen that tooth. Check that the tooth
has sharpened completely, adjusting the
chainstop if necessary.
7. The chain can now be moved to the next tooth in that row to sharpen.
8. The angle plate will need to be rotated to sharpen the alternate teeth on the chain and then
repeat the process. When sharpening the alternate teeth double check that the tooth length
is the same as the first row that have been sharpened. Very fine adjustment of the chainstop
may be necessary.
