TINE REPLACEMENT
The cultivator/tiller is left hand or right hand
as viewed from the operator's position be-
hind the unit.
All four tines on this unit are different and
cannot be interchanged. The tines must be
properly installed as shown in figures to the
right or the cultivator/tiller will not function
properly.
For working close around plants or in small
areas, the outside tines may be removed to
reduce the tilling width to about 7 inches. To
reinstall the outside tines see below.
CAUTION: The tines are self sharp-
ening and wilt become quite sharp from
use° Handle carefully.
The tines will all wear fairly evenly_ If the
tines are being replaced because of wear,
we recommend that all four tines be re-
placed at the same time. To replace the
tines, do the following:
- Place the on-off switch to the OFF
position and disconnect the spark plug
wire.
, While wearing gloves, remove the
hairpins and the clevis pins from the tines
on one side of the unit and then remove
the tines. See figure, previous page.
- Clean the tine shaft and oil it at the tine
locations.
° Place the inside tine on the fine shaft and
reinstall the clevis pin and hairpin.
• When the tines are properly installed, the
letter R will be visible on the outside of
the right-hand fine (the letter L on the left-
hand tine). The letter should appear
opposite the small hole in the side of the
tine.
° Place the outside tine on the tine shaft
and reinstall the clevis pin and hairpin.
• The outside tine cutting tips will all bend
in toward the inside tine. The letter R on
the right side or L on the left side should
be visible from the outside of the unit.
° Repeat the above steps on the opposite
side of the unit.
• Check to make sure the tines are
installed on correct side of the unit.
