Before Starting Work; Switching On The Machine - Stihl TSA 230 Manual De Instrucciones

2 Safety Precautions
STIHL generally recommends wet cutting.
Observe the outside diameter of the
abrasive cutting wheel – refer to the
chapter "Specifications".
Spindle hole diameter of the abrasive
cutting wheel and shaft of the cut-off
machine must match – refer to the
chapter "Specifications".
Check the spindle hole for damage. Do not use
abrasive cutting wheels with a damaged spindle
hole – risk of accident!
The permissible speed of the abra‐
sive cutting wheel must be equal to or
greater than the maximum spindle
speed of the cut-off machine. – Refer
to the chapter "Specifications".
Before fitting a used abrasive cutting wheel,
check that it is not cracked, chipped, undercut or
uneven, and does not display any signs of core
fatigue or overheating (discoloration); check also
that there are no damaged or missing segments
and that the spindle hole is not damaged.
Never use cracked, chipped or bent abrasive cut‐
ting wheels.
Substandard and/or unapproved diamond abra‐
sive cutting wheels can shimmy during cutting.
This shimmying can cause such diamond abra‐
sive cutting wheels to be abruptly braked or
become stuck in the cut – Danger of kickback!
Kickback can result in fatal injuries! Diamond
abrasive cutting wheels that shimmy constantly
or even only intermittently must be replaced
immediately.
Never straighten diamond abrasive cutting
wheels.
Do not use an abrasive cutting wheel which has
fallen to the ground – damaged abrasive cutting
wheels may break – risk of accident!
Observe the expiration date where resin abrasive
cutting wheels are concerned.
2.9.2 Fitting abrasive cutting wheels
Inspect the spindle of the cut-off machine. Do not
use a cut-off machine if the spindle is damaged –
risk of accident!
Note the arrows indicating the direction of rota‐
tion on diamond abrasive cutting wheels.
Position the front pressure plate – tighten up the
clamping screw – rotate the abrasive cutting
wheel by hand and take a sight check for con‐
centricity and axial running.

2.9.3 Storing abrasive cutting wheels
Store abrasive cutting wheels in a dry and frost-
free place, on a flat surface, at constant tempera‐
ture – risk of breakage and splintering!
Always protect the abrasive cutting wheel
against sudden contact with the ground or
objects.

Before starting work

Inspect the parting-off grinder for safe-to-operate
state – observe the respective chapters in the
instruction manual:
– Trigger switch and trigger switch lockout must
move easily – trigger switch and trigger switch
lockout must return to initial position when
released
– The abrasive wheel must be suitable for the
material to be cut. It must be in good condition
and fitted correctly (direction of rotation,
secure).
– Trigger switch is locked when the trigger
switch lockout is not depressed
– Locking lever easy to set to ‚ or ƒ
– Never attempt to modify the controls or safety
devices in any way
– Keep the handles clean, dry and free of oil as
well as dirt – important for safe guiding of the
parting-off grinder.
– Check contacts in the battery compartment of
the cut-off machine for foreign matter and dirt
– Fit the battery correctly – it must engage audi‐
bly
– Do not use defective or deformed batteries
– For wet applications, provide sufficient water
The cut-off machine should only be used if it is in
full working order – risk of accident!
2.11

Switching on the machine

On even ground, ensure a firm and secure foot‐
ing and hold the cut-off machine firmly – the
abrasive wheel must not touch any objects or the
ground and must not be in cutting action.
The cut-off machine is a one-person unit. Do not
allow other persons to be near the machine.
Switch on as described in the Instruction Manual
– see "Switching on the machine".
After releasing the trigger switch, the abrasive
wheel keeps on running for a while – danger of
injury due to coasting effect!
