Assembling The Bearing And Guard - Stihl TS 400 Instruction Manual

English
Undercut
Do not cut into the base course
(frequently chipped stones and gravel)
when cutting roadway pavement –
cutting in chipped stones and gravel is
revealed by light-colored dust –
excessive undercut may occur as a
result – Danger of shattering!
Built-up edges, sharpen
Built-up edges take the form of a light
gray deposit on the tops of the diamond
segments. This deposit on the segments
clogs the diamonds and blunts the
segments.

Built-up edges can form:
when cutting extremely hard
–
materials, e. g., granite
with incorrect handling, e. g.,
–
excessive feed effort
if excessively large cross-sections
–
are cut without pendulum cutting
(movement back and forth in the
cutting plane)
Built-up edges increase vibration,
reduce cutting performance, and cause
formation of sparks.
At the first signs of built-up edges,
immediately "sharpen" the diamond
cutting wheel – to do this, briefly cut
through abrasive material such as
sandstone, aerated concrete or asphalt.
Addition of water prevents the formation
of built-up edges.
If work continues with dull segments,
these may soften due to the high heat
generated – the parent wheel is
annealed and its strength is
compromised – this can lead to stresses
that are clearly recognizable by
gyrations of the cutting wheel. Do not
continue to use the cutting wheel – Risk
of accident!
Assembling the bearing and
guard
A
1
The "bearing with guard" can be
mounted on the inboard or outboard side
of the cast arm depending on
requirements. Assembly on the inboard
side is recommended for freehand
cutting on account of improved balance;
outboard mounting is recommended
when the machine is mounted on a
STIHL cut-off machine cart.
for outboard mounting, fasten the
N
adjusting lever (1) in Position A
