the area where fuel is handled
or stored.
• Never use oil for 4 cycle
engine use or water cooled
2-cycle engine.
• Never use “FUEL WITH
NO OIL (NEAT UNLEADED
PETROL)”.
• Never use fuel laced with
water.
• Mixed fuels which have
been left unused for a period
of one month or more may
clog the carburetor or result in
the engine failing to operate
properly. Put remained fuel into
an air-tight container and keep
it in the dark and cool room.
• Please ask for “mixed
gasoline for air-cooled 2-cycle
engines” at your nearest gas
station, or use fuel made by
putting unleaded gasoline for
automobiles and air-cooled
2-cycle engine oil into a mixing
container in accordance with
the following ratios and then
shaking to mix well.
Mixing ratios:
When using commercially
available 2 stroke oil:

OIL
It is recommended that you use
a high quality 2 stroke oil in this
machine with an ethanol shield.
Sherpa recommends use of
B3C oil in the wheeled trimmer,
when using this product you
are able to mix petrol to oil at
a 50:1 ratio, as opposed to the
usual 40:1 with other 2 stroke
oils.

STORAGE
Aged fuel is one of major
causes of engine starting
failure. Before storing the unit,
empty the fuel tank and run
the engine until it uses all the
fuel left in the fuel line and the
carburetor. Store the unit indoor
taking necessary measures for
rust prevention.

up for several minutes before
starting operation.
1. When restarting the engine
immediately after stopping it,
leave the choke open (OP2)
and push the primer pump
several times (OP4).
2. Overchoking can make the
engine hard to start due to
excess fuel. If the engine failed
to start after several attempts,
open the choke and repeat
pulling the rope, or remove the
spark plug and dry it.
STOPPING ENGINE
1. Release the throttle lever
and run the engine for a half
minute.
2. Shift the ignition switch to the
STOP position.
Except for an emergency,
avoid stopping the engine while
pulling the throttle lever.
ADJUSTING IDLING SPEED
(OP5)
1. If the engine tends stop
frequently at idling mode, turn
the adjusting screw clockwise
a fraction.
2. When the cutting head keeps
rotating after releasing the
trigger, turn the adjusting screw
anticlockwise.
Warm up the engine before
adjusting the idling speed.
