Empty the fuel tank with a suction pump.
Be careful! Do not discharge gasoline in a closed room or near an open flame. do not smoke! This can cause an explosion or fire.

Remove the spark plug. Approximately 20 ml of oil was injected into the combustion chamber using a syringe. Pull the starter disk to evenly distribute the
oil in the combustion chamber.
2. Clean and lubricate the machine carefully as described in the Lubrication Instructions above.
3. Gently apply the rust inhibitor to the impeller and exposed metal parts to avoid corrosion.
4. Store the machine in a dry, clean, frost-proof place away from unauthorized personnel
Be careful! The engine must be completely cooled before storing the machine.

The importance of proper maintenance
●
Proper maintenance is critical to safe, economical and trouble-free
operation; it also helps reduce air pollution.
Improper maintenance or failure to correct problems prior to operation
can result in serious injury or death.
●
Always follow the maintenance recommendations and schedules in this
instruction manual.
To help you properly maintain your machine, the following pages include
maintenance plans, routine inspection procedures, and simple maintenance
procedures using basic hand tools. Other maintenance tasks that are more
difficult or require special tools are best handled by professionals, usually
by our technical staff or other qualified mechanics.
The maintenance plan is for normal operating conditions. If you operate the
machine under harsh conditions, such as continuous high load or high
temperature operation, or in unusually humid temperatures, consult your
service dealer for advice that is appropriate for your individual needs and
use.
Maintenance, replacement or repair of the emission control devices and
systems can be performed by any engine service facility or individual
using components that meet the EPA standards in the "Certification".

Routine maintenance
1. Oil maintenance
Before each use of the machine, check the oil level to see if it is between the upper and lower scales of the oil gauge (see Fig 39-2).
。
The new
machine is run for 4 hours before use to achieve the best effect of the machine. After the running-in period, please replace the oil. The oil should be
replaced after 25 hours of use, and the oil should be changed periodically according to the instructions.
The oil change should be carried out after the engine is in the heat engine. Do not add too much oil, otherwise it will appear: black smoke, no
power (excessive cylinder carbon deposit, small spark plug clearance). Engine overheating. Filling the engine oil should not be too small, otherwise it
will appear: the engine gear is noisy, the piston ring accelerates wear and damage, and even the piston jams, causing serious damage to the engine.
When changing the oil, the machine must be tilted in the direction of the oil port, you can pour it out and replace it with new oil, but you can't tilt it to
the other side. Otherwise, the oil will flow into the carburetor, causing damage to the carburetor.
