cutter knife lock bar from the cutter
block.
Clean all surfaces of cutter block
and cutter knife lock bar with a
suitable solvent (do not use cleaning
agents that could corrode the light
metal components).
Knife installation:
Use only suitable cutter knives

dull, cracked of bent cutter knives
can work loose or increase the risk
of kickback considerably.

randomly be placed.
Only cutter knives marked “HSS” or
“HS” can be resharpened!
When resharpening, remove the
same amount of material from both
cutter knives, otherwise a balancing
error may cause damage to the
bearings.
Cutter knives can only be
resharpened down to a minimum
width of 14 mm.
Use genuine Jet replacement parts
only.
