Spark Plug - Texas ZS 50 TR/W User Manual

Oil change
The oil must be changed after the first 5 hours of use. After that the oil must be changed at
least once a year.
1. Let the engine run for 5 minutes to warm up the oil. This makes it run easier and
make the oil change more complete.
2. Turn off the engine after 5 minutes. Take off the spark plug cap. Unscrew the
cork for the drain plug. Theo oil now runs out of the engine. Keep a suitable
container ready to collect the oil.
NOTE that the engine may only be tilted backward at an angle of max 45
degrees.
Refit the drain plug and pour fresh oil into the engine.
3. This is done by removing the oil stick and filling with correct amount of oil.
4. Mount the spark plug cap.
Alternatively use an oil changing kit:
1. Suck the oil up through the oil filler hole using the
syringe. (See the section Identification of parts, Pos
C.) Use the hose as an extension piece to reach the
bottom of the engine. Transfer the used oil to the
accompanying container.
2. Fill the engine with new oil, type SAE30.
Check the oil level using the dipstick on the oil bung
Remember to dispose of the used oil so that it is not harmful to nature.
Use your local recycling station. Oil and oil changing kit is not included.
