Reactive Forces - Stihl TSA 230 Instruction Manual

English
Vibrations
Prolonged use of the power tool may
result in vibration-induced circulation
problems in the hands (whitefinger
disease).
No general recommendation can be
given for the length of usage because it
depends on several factors.
The period of usage is prolonged by:
Hand protection (wearing warm
–
gloves)
Work breaks
–
The period of usage is shortened by:
Any personal tendency to suffer
–
from poor circulation (symptoms:
frequently cold fingers, tingling
sensations).
Low outside temperatures.
–
The force with which the handles
–
are held (a tight grip restricts
circulation).
Continual and regular users should
monitor closely the condition of their
hands and fingers. If any of the above
symptoms appear (e.g. tingling
sensation in fingers), seek medical
advice.
Maintenance and repairs
Before all repair and maintenance work,
always switch off the machine, set the
locking lever to ƒ and remove the
battery from the cut-off machine. If the
abrasive wheel starts inadvertently – risk
of injury!
8
The cut-off machine must be serviced
regularly. Do not attempt any
maintenance or repair work not
described in the Instruction Manual. All
other work should be carried out by a
servicing dealer.
STIHL recommends that maintenance
and repair work be carried out only by
authorized STIHL dealers. STIHL
dealers receive regular training and are
supplied with technical information.
Use only high-quality spare parts.
Otherwise, there may be a risk of
accidents and damage to the cut-off
machine. If you have any questions in
this respect, consult a servicing dealer.
STIHL recommends the use of genuine
STIHL spare parts. They are specifically
designed to match your cut-off machine
and meet your performance
requirements.
Do not modify the cut-off machine in any
way – this can be extremely dangerous
–risk of accidents!
Check existing electrical contacts,
power cords and power plug of the
charger regularly for undamaged
insulation and aging (brittleness).
Electrical components, e.g., the power
cord of the charger, may only be
repaired and/or replaced by qualified
electricians.

Reactive Forces

The most frequently occurring reactive
forces are kickback and pull-in.
Kickback
Danger of kickback –
Kickback can result in
fatal injuries.
Kickback occurs when the cut-off
machine is suddenly thrown up and back
in an uncontrolled arc towards the
operator.
Kickback occurs if, for example, the
abrasive cutting wheel
gets jammed – especially the upper
–
quarter, or
is abruptly braked through friction
–
contact with a solid object
Reducing the risk of kickback
Work cautiously and methodically
–
Hold the cut-off machine firmly with
–
both hands and maintain a secure
grip
