for changing load, be sure to switch OFF the circuit
breaker, remove the starter key from the starter
switch, then perform work.
WARNING Contact with rotating parts or
belts could cause death or serious injury. Keep hands
from rotating parts and belts while machine is in
operation.
WARNING Do not open radiator
cap during or immediately after operation. Explosive
pressure of hot liquid could cause severe burns,
resulting in death or serious injury.
WARNING Do not touch hot parts.
• Never work nearby hot portions of the machine while

WARNING Fire prevention.
• Fuel and oils are extremely flammable. Do not bring
ignition sorces near machine when checking or
adding fuel and oils.
• Adding fuel and oils should be done outdoors or in a
well-ventilated location.
• Refuel after stopping engine, and never leave
fuel near machine. Do not spill. If spilled, wipe up
completely.
• Do not fill fuel oil up to cap level. Fuel oil will overflow
due to volume expansion caused by rise of ambient
temperature. Fuel can also spill during machine
movement or transporting.
• Parts such as muffler and exhaust pipe can be
extremely hot. Remove twigs, dried leaves, dried
grass, waste paper, etc. from around muffler and
exhaust pipe.

• Work lighting should be fitted with safety guard to
protect against breakage.
• Do not allow work light to contact fuel or oils, as they
could ignite, causing death or serious injury.
