OPERATION METHOD
KEY POINTS OF TREATMENT
when cutting wet grass, the grass cut inside the cutter cover is easy to pile up，accumulation will cause unreason-
able load to the machine, so please wait for the grass to dry then start working, or often clean up the accumulated
inside the cutter coverStraw residue.
when the mower is overloaded, please shift to "forward" or "1", or Increase the mowing height and cut twice or reduce
the mowing width. (wet) grass, long grass, dense grass, etc.
If the engine throttle is not adjusted to the maximum, put in the cutter clutch the engine may stall.
please operate after the cutter is fully rotated. Low cutter speed the engine may shut down or the grass may not be
cut clean.
sometimes long grass and vine like grass will be entangled on the cutter and cannot be used well cut.

WARNING
To prevent injury accidents
Do not touch the plug cover or high�
voltage line when pulling the start-
ing pull plate. One touch will "get
an electric shock".
WARNING
To prevent injury accidents
If you continue to use the cutter
not installed in place or damaged
parts or extremely worn cutter, it
will cause vibration damage to the
machine, which is very dangerous.
Please check it before operation.
When replacing worn cutters,
please replace all (38 pieces) at
the same time. (once the rotating
balance collapses, the vibration
will increase, which is ver y danger-
ous)
WARNING
Remove the spark plug s leeve and remove the spark
plug with the attached box wrench. Remove the
carbon deposit on the spa r k plug and adjus t the
electrode gap to "0.02 ~ 0.03 inch".
When the electrode part is worn or damaged, please
replace it with a new spark plug.
After installing the spark plug, make sure that the

To prevent injury accidents
If the protective cover is cracked,
deformed or shortened, there will
be more foreign matters such as
stones flying out, because it is
very dangerous, please replace it in
time.
WARNING
To prevent injury accidents
Clean, check and adjust the
machine in a flat place until all
parts stop running.
After adjustment, try whether the
machine is abnormal.
WARNING
To prevent injury accidents
Stop the engine and then adjust
the travel clutch.
After starting the engine and
confirming that the belt is not
rotating, shift the gear lever into
"n" gear. Don't get close to people
or objects. Don't get close to the
engine pulley or belt with your
hands and feet.
Ins tall the belt cover after adjust-
ment.
Please don't adjust the belt too
tight. If the belt is too tight, the
walking clutch rod cannot be
disconnected, which may cause
accidents.
WARNING
All pa rt s ha ve be en prope rly debugged before leaving
the factory, but due to wear and tension during use, they
should be debugged and replaced with parts exceeding
the loss limit to make them in a state of normal use.
If the corner of the cutter is seriously worn, it is
necessary to change the cutter to a new side and cut
the grass with a new side
The cutting knife (38 pieces in total) is fixed on the
connecting accessories (19 places in total) with
bolts on the back of each two pieces.
Screw in the flat direction of the fastening nut
towards the bolt.
After tightening the bolt and fastening nut with tools,
the bolt protrudes more than 2 threads from the end
face of the fastening nut. Please make sure that the
two cutters can rotate freely in the cutter connecting
accessories.
The traveling clutch rod is belt tensioned, and the travel-
ing clutch is not adjusted well. If it is too loose, it will lead
to low operation efficiency and performance, and acceler-
ate the wear of V-belt.
In addition, the belt is too tight, the travel clutch rod
cannot be disconnected, and the machine will not stop.
