ENGINE OIL
CAUTION! A
This engine is delivered without oil, be sure to put oil in the engine before the starting.
Use only below recommended types of oil.
RECOMMENDED OIL
Use 4-stroke motor oil that meets or exceeds the requirements for API service classification SH,
SJ, or equivalent. Always check the API service label on the oil container to be sure it includes
the letters SH, SJ, or equivalent.
SAE 10W-30 is recommended for general use in the summer (for temperatures above 0°C) -
recommended oil HECHT GARDEN 4T.
SAE 5W-40 is recommended for general use in winter (for temperatures below 0°C) -
recommended oil HECHT 5W-40.
Choose optimal oil viscosity that match the ambient temperature at which you are
going to operate the machine. DO NOT MIX OILS!
OIL LEVEL CHECK
CAUTION! A
Only check oil level with cold engine.
1. Place engine level. Check the oil level with the engine stopped and cooled down.
2. Remove the oil filler cap/dipstick (fig. 18A) and wipe it clean.
3. Insert the oil filler cap/dipstick into the oil filler neck until it stops, but do not screw it in.
Then remove it. Now read off the oil level on the dipstick.
4. If the oil level is near or below the lower limit mark on the dipstick, fill with the recommended
oil into the engine between the upper and lower mark. Do not overfill.
CAUTION! A
Running the engine with insufficient oil can cause serious engine damage.
5. Reinstall the oil filler cap/dipstick.
HIGH ALTITUDE
• 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 installing a smaller diameter main fuel jet in
the carburetor. If you always operate the machine at altitudes higher than 1600 m above
sea level, have your authorized dealer install the high altitude main jet.
• This machine will not perform well at high altitudes without proper adjustment. Contact
a authorized service center for adjustment information.
