Carbide-tipped chain
Cutter
Cutters are tipped with carbide.
Large-area brazing of carbide
tipping to top plate increases
strength.
Depth gauge
Forward projecting.
Construction of chain
A triple-humped tie strap installed
on the opposite side of the chain in
front of each cutter. It reduces the
tendency of the cutter to sit up and
snag.
Applications
Primarily for special applications
(rescue services, fire and
emergency services, etc.).
Maintenance
Resharpening of the extremely hard
carbide tips requires a special
diamond grinding wheel and the
STIHL USG electric sharpener.

Micro
(PM)
Low vibration, low profile semi-
chisel chain
Cutter
Slim, straight-sided, low profile
cutter for reduced kickback
tendency.
Depth gauge
Forward projecting depth gauge
reduces kickback tendency.
Function
The bottoms of the cutters and tie
straps slope upwards to the rear –
this clearance allows the cutters to
rock back slightly and thus produce
a shock absorbing effect – very low
vibrations and high cutting capacity.
Applications
Agriculture and building industry, as
well as occasional users; limbing in
small stands on lightweight saws.
Maintenance
Resharpening is accomplished with
a round file with file holder, a filing
tool or electric chain grinder.
