Working safely with cut-off machines

English

3

STIHL cut-off machines are 
equipped with an anti-vibration 
("AV") system designed to reduce 
the transmission of vibrations 
created by the machine to the 
operator's hands. An AV system is 
recommended for those persons 
using cut-off machines on a regular 
or sustained basis.

Wear gloves and keep your hands 
warm.

Keep the AV system well 
maintained. A cut-off machine with 
loose components or with damaged 
or worn AV elements will tend to 
have higher vibration levels.

Maintain a firm grip at all times, but 
do not squeeze the handles with 
constant, excessive pressure. Take 
frequent breaks.

All the above-mentioned precautions do 
not guarantee that you will not sustain 
whitefinger disease or carpal tunnel 
syndrome. Therefore, continual and 
regular users should monitor closely the 
condition of their hands and fingers. If 
any of the above symptoms appear, 
seek medical advice immediately.

Proper Clothing

Clothing must be sturdy and snug-fitting, 
but allow complete freedom of 
movement. Avoid loose-fitting jackets, 
scarfs, neckties, jewelry, flared or cuffed 
pants, unconfined long hair or anything 
that could become caught on any 
obstacles or moving parts of the unit. 
Wear overalls or long pants to protect 
your legs. Do not wear shorts.

Wear an approved safety hard hat to 
protect your head. Cut-off machine 
noise may damage your hearing. Always 
wear sound barriers (ear plugs or ear 
mufflers) to help protect your hearing. 
Regular users should have their hearing 
checked regularly.

Warning!

The ignition system of your unit pro-
duces an electromagnetic field of a very 
low intensity. This field may interfere 
with some pacemakers. To reduce the 
risk of serious or fatal injury, persons 
with a pacemaker should consult their 
physician and the pacemaker manufac-
turer before operating this tool.

Warning!

To reduce the risk of 
injury, the operator 
should wear proper pro-
tective apparel.

Warning!

When cutting metal, a cut-off machine 
generates sparks that can ignite cloth-
ing. Most fabrics used in clothing are 
flammable – even flame-retardant fab-
rics will ignite at higher temperatures. 
To reduce the risk of burn injury STIHL 
recommends wearing clothing made of 
leather, wool, flame-retardant-treated 
cotton or a tightly woven, heavier cotton 
such as denim. Some flame-retardant 
synthetic fabrics are also suitable, but 
others such as polyester, nylon, rayon 
and acetate can melt during a fire into a 
tar-like matter that burns into the skin. 
Check the clothing manufacturer's 
instructions. Keep clothing free of oil, 
fuel, grease and other flammable 
substances.

Always wear gloves 
when handling the cut-off 
machine. Heavy-duty, 
nonslip gloves improve 
your grip and help to pro-
tect your hands.

Good footing is important 
in cut-off machine work. 
Wear sturdy boots with 
nonslip soles. Steel-toed 
safety boots are 
recommended.

Warning!

Loose objects may be thrown toward 
the operator by the cutting tool.

To reduce the risk of 
injury to your eyes never 
operate a cut-off machine 
unless wearing goggles 
or properly fitted safety 
glasses with adequate 
top and side protection 
complying with 
ANSI Z 87.1. Proper eye 
protection is a must.
