NOTICE
The standard distance between the joints of the brace (
3 in), but make sure that the maximum tilt does not exceed 400 mm (15.8 in).
If the tilt exceeds 400 mm (15.8 in), there will be excessive force brought to
bear on the parts, so do not use with a tilt of more than 400 mm (15.8 in).
ADJUSTING RIPPER
ADJUSTING DIGGING DEPTH
There are mounting holes in the shank to chose to match the ripping depth. Normally, use the bottom hole, but if
particularly deep ripping is needed, use the top hole.
When changing the digging depth, do as follows.
1. Place a pointed object on the tip of pin (1), then hit with a
hammer to remove from the opposite side.
2. Remove pin (2) and change the position of the shank hole.
3. Insert pin (1) partially by hand then knock it in with a hammer.
The pin is one unit, so when inserting, insert it partially by
hand, then knock it in with a hammer.
When a giant ripper is installed, use the pin puller.
For details, see "METHOD OF OPERATING PIN PULLER
(PAGE 3-147)".
REPLACING POINT AND PROTECTOR
To protect the shank, replace the point and protector installed to
the tip of the shank when they are worn.
Put a pin removal bar in contact with the pin marked by the arrow,
then hit it with a hammer and remove it from the opposite side.
