ways be sure to turn off the en-
gine before turning around.

 MAINTENANCE

1.  In order to maintain your product

the maintenance and checking 
operations described in the 
manual at regular intervals.

2. Always be sure to turn off the 

engine and disconnect the spark

maintenance or checking proce-
dures.

WARNING

The metallic parts reach high tem-
peratures immediately after stop-
ping the engine.

3. When replacing the cutting at-

tachment or any other part, or 
when replacing the oil or any lu-
bricant, always be sure to 

use 

only  ZENOAH    products  or 
products which have been cer-
tified by ZENOAH for use with 
the ZENOAH product

.

4.  In the event that any part must be 

replaced or any maintenance or 
repair work not described in this 
manual must be performed, 
please contact a representative 
from the store nearest ZENOAH 
authorized servicing dealer for 
assistance.

5. Do not use any accessory or at-

tachment other than those bear-
ing the ZENOAH mark and rec-
ommended for the unit.

6. Under no circumstances should 

you ever take apart the product 
or alter it in any way. Doing so 
might result in the product be-
coming damaged during opera-

tion or the product becoming 
unable to operate properly.

 HANDLING FUEL

1.  The engine of the  ZENOAH prod-

uct is designed to run on a mixed 
fuel, which contains highly flam-
mable gasoline. Never store cans 
of fuel or refill the tank of the unit 
in any place where there is a 
boiler, stove, wood fire, electrical 
sparks, welding sparks, or any 
other source of heat or fire which 
might ignite the fuel.

2.  Never smoke while operating the 

unit or refilling its fuel tank.

3. When refilling the tank, always 

turn off the engine and allow it to 
cool down. Take a careful look 
around to make sure that there 
are no sparks or open flames 
anywhere nearby before refuel-
ing.

4. Wipe spilled fuel completely us-

ing a dry rag if any fuel spillage 
occurs during refueling.

5.  After refueling, screw the fuel cap 

back tightly onto the fuel tank and 
then carry the unit to a spot 3 m 
or more away from where it was 
refueled before turning on the 
engine.

 TRANSPORTATION

1.  When hand-carrying the product, 

cover over the cutting part if nec-
essary, lift up the product and 
carry it paying attention to the 
blade.

2.  Never transport the product over 

rough roads over long distances 
by vehicle without removing all 
fuel from the fuel tank. If doing so, 
fuel might leak from the tank dur-
ing transport.

WARNING

THRUST

Blade  thrust  can  cause  serious 
personal  injury.  Carefully  study 
this  section.  It  is  important  that 
you  understand  what  causes 
blade thrust, how you can reduce 
the  chance  of  blade  thrust  and 
how you can remain in control of 
the unit if blade thrust does occur.
