TINE REMOVAL AND REPLACEMENT
All 4 tines should be replaced at the same time because they will
wear evenly through normal use. Work on one side at a time.
1. Put the On/Off Stop Control in the STOP (O) position
and disconnect the spark plug wire.
NOTE: It may be necessary to lay the cultivator back in a
horizontal position on a flat level surface with the
upper handle touching the ground.
2. Remove the click pin from each end of the tine shaft. Slide
the tines off of the shaft (Fig. 14).

5. Place one “A” tine and one “B” tine onto the shaft.
6. Secure the new tines to the shaft with click pins. It may be
necessary to wash the dirt off the tines and shaft for ease
of removal.
CHECKING THE OIL LEVEL
The importance of checking and maintaining the proper oil
level in the crankcase cannot be overemphasized. Check oil
before each use:
1.
Stop the engine and allow oil to drain into the crankcase.
2. Place the unit on a flat, level surface to get a proper oil
level reading (Fig. 9).
3. Keep dirt, grass clippings and other debris out of the
engine. Clean the area around the oil fill plug/dipstick
before removing it.
4. Remove the oil fill plug/dipstick and wipe off oil. Reinsert it
all the way back in.
5. Remove the oil fill plug/dipstick and check the oil level. Oil
should be up to the top of the dipstick (Fig. 15).
6. If the level is low, add a small amount of oil to the oil fill hole
and recheck (Fig. 16). Repeat this procedure until the oil level
reaches the top of the dipstick.
NOTE: Do not overfill the unit.
