TINE REMOVAL AND REPLACEMENT
All tines should be replaced at the same time as they will wear evenly
through normal use. Work on one side at a time.
1.
Make sure the unit is off.
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. It
may also be necessary
to wash any dirt off the
tines and shaft for ease
of removal.
2.
Remove the click pin from
each end of the tine shaft. Slide the tines off of the shaft (Fig. 12).
3.
Clean and oil the shaft.
4.
Slide on the new tines with the hubs facing each other (Fig. 12).
NOTE:
Each tine has a convex side. Make sure that all of the convex
sides are facing as shown in Figure 12.
5.
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
WARNING:
To avoid serious personal injury, always turn the
unit off and allow it to cool before cleaning or maintaining it.
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 in a horizontal
position to get a proper oil
level reading (Fig. 13).
3.
Keep dirt, grass clippings
and other debris out of the
engine. Clean the area
around the dipstick before
removing it.
4.
Remove the oil fill plug.
5.
Look into the oil fill hole, use
a flashlight if needed. The oil
should be just touching the
inner most thread (Fig. 14).

amount of oil to the oil fill hole
and recheck (Fig. 17). Repeat
this procedure until the oil
level reaches the inner most
thread on the oil fill hole.
