Note:
Use a wrench on the square neck of the bolt to
prevent the bolt from spinning.
4.
Repeat the procedure for the other stop bolt.
5.
Ensure that the rake does not contact the tires
throughout the range of motion.
Inspecting the Raking Pattern
and Adjusting the Lift-in-turn
System
Inspecting the Raking Pattern
1.
Ensure that the tires are inflated to 48 kPa (7 psi).
2.
Drive the machine to a sand trap—with a flat bottom,
if possible.
3.
With the rake in the lowered position, turn the machine
to the left while driving, so that the rake is fully pivoted.
4.
Stop the machine, stop the engine, set the parking
brake, remove the key, and wait for all moving parts
to stop.
5.
Get off the machine, and inspect the left-hand side of
the raking path in the sand.
Note:
The rake should groom over the tire tracks, but
it should not contact the sand beyond the tire tracks.
If the raking path is not correct, refer to Adjusting the
Lift-in-turn System (page 11).
6.
Repeat the procedure for the right-hand side of the
rake.
Adjusting the Lift-in-turn System
1.
Complete steps 1 through 5 in Inspecting the Raking
Pattern (page 11).
2.
Pivot the rake fully to 1 side.
3.
On the inside of the turn (for example, the left-hand
side if the rake is pivoted to the left), determine
whether the rake contacts the sand too much and
grooms beyond the tire tracks, or does not contact the
sand enough to groom over the tire tracks.
4.
Note the hole to which the top of the cable is mounted.
5.
Remove the shoulder bolt and the flange nut, and move
the end of the cable to the appropriate hole.
•
If the rake contacts the sand too much and grooms
beyond the tire tracks, move the top of the cable to
a hole closer to the center of the boom.

•
If the rake does not contact the sand enough to
groom over the tire tracks, move the top of the
cable to a hole further away from the center of
the boom.
6.
Secure the cable with the shoulder bolt and the flange
nut.
Note:
To decrease the chance of binding, ensure that
the end of the cable is positioned as shown in Figure 20.
7.
Repeat the procedure for the other side.
Adjusting the Rake Pitch
You can adjust the pitch of the rake to increase or decrease
the amount of material agitation. If the rake edge is angled
forward (Figure 21), toward the machine, the rake will carry
more material and agitate the material at a deeper level. If
the rake edge is angled backward (Figure 23), away from
the machine, the rake will carry less material and agitate the
material at a shallower level.
