High Altitude Operation - Honda Power Products WJR2525 Manual De Explicaciones

Hot Restart
If the engine is operated at higher ambient temperatures then turned
off and allowed to sit for a short time, it may not restart on the first
pull.
If necessary, use for following procedure:
IMPORTANT SAFETY PRECAUTION
Turn the engine switch to the OFF position before performing the
following procedure. This will prevent the engine from starting and
running at maximum speed when the throttle is in the full throttle
position. If the engine starts, with the throttle in the full throttle
position, agricultural chemicals may splash on you if the shut-off
valve is in the "OPEN" position. This may result in personal injury.
1. Turn the engine switch to the OFF position.
2. Move the choke lever to the OPEN position.
3. Move the throttle lever in the full throttle position (FAST).
4. Pull the starter grip 3 to 5 times.
5. Follow the STARTING THE ENGINE procedure on page 38 and start
the engine with the choke lever in the OPEN position.

• High altitude operation

At high altitude, the standard carburetor air-fuel mixture will be
excessively rich. Performance will decrease, and fuel consumption
will increase.
High altitude performance can be improved by specific modifications
to the carburetor. If you always operate the backpack sprayer at
altitudes higher than 1,500 m above sea level, have your authorized
Honda dealer perform these carburetor modifications.
Even with suitable carburetor jetting, engine horsepower will
decrease approximately 3.5% for each 300 m increase in altitude. The
effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
CAUTION:
Operation of the backpack sprayer at an altitude lower than the
carburetor is jetted for may result in reduced performance,
overheating, and serious engine damage caused by an excessively
lean air/fuel mixture.
