Fuel Filler Cap with Screw Thread

This reduces the risk of the cap working 
loose due to engine vibrations and fuel 
leaking out.

Before use, make sure that the fuel cap 
has been properly tightened and any 
spilled fuel wiped away. Check for fuel 
leakage while refueling and during 
operation. If a fuel leak is suspected, do 
not start or run the engine until the leak 
is fixed and spilled fuel has been wiped 
away.

Before Starting

For assembly, follow the procedure 
described in the appropriate section of 
your instruction manual.

Never operate a cut-off machine that is 
damaged, improperly adjusted or not 
completely and securely assembled. 
Check machine that it is ready for proper 
operation.

Keep the handles dry, clean and free of 
oil and fuel.

Proper tensioning of the ribbed V-belt is 
important. In order to avoid an incorrect 
setting, the tensioning procedure must 
be followed as described in your 
manual. Always make sure the 
hexagonal collar nuts for the cast arm 
are tightened securely.

Check ribbed belt tension after one hour 
of operation and correct if necessary.

Starting

Do not drop start. This method is very 
dangerous because you may lose 
control of the cut-off machine. Place the 
cut-off machine on firm ground or other 
solid surface in an open area. Maintain 
good balance and secure footing. Be 
absolutely sure that the cutting wheel is 
clear of you and all other obstructions 
and objects, including the ground. When 
the engine starts at starting-throttle, 
engine speed will be fast enough for the 
clutch to engage the belt pulley and turn 

Tighten the fuel filler cap 
as securely as possible 
after refuelling.

Warning!

Never attempt to force the cap open by 
using a tool. It may damage the cap and 
allow fuel to leak.

Warning!

Before operation of your cut-off 
machine, be sure the controls (e.g. 
throttle trigger, throttle trigger lockout, 
stop switch) and the safety devices are 
working properly, the carburetor idle 
and maximum speed are correctly 
adjusted, the wheel is properly 
mounted, and the wheel guard is in 
place and securely fastened to your 
unit. All wheels should be carefully 
inspected for good condition before 
mounting.

Adjust the wheel guard 
so that sparks, dust and 
cut material are deflected 
away from the operator, 
and cannot reach flam-
mable surroundings. See 
section "Operating 
Instructions" of your 
instruction manual.

Warning!

Check that the spark plug boot is 
securely mounted on the spark plug – a 
loose boot may cause arcing that could 
ignite combustible fumes and cause a 
fire.

Warning!

Your cut-off machine is a one-person 
tool. Do not allow other persons to be 
near a running cut-off machine. Start 
and operate your cut-off machine with-
out assistance. For specific starting 
instructions, see the appropriate section 
of your instruction manual.
