BASIC COMPONENTS (HYDRAULIC)
Figure 3 illustrates the hydraulic components used on the
mixer.
1.
Hydraulic Motor —
Bi-directional hydraulic motor that
is used in conjunction with the directional control valve
to operate the hydraulic dump cylinder and paddle
shaft.
2.
Hydraulic Oil Cap —
Remove this cap to add hydraulic
oil to the hydraulic oil tank. Fill with hydraulic oil as
listed in Table 1. Make sure cap is tightened securely.
3.
Hydraulic Oil Tank —
This tank has a capacity of 12
gallons (45 liters). Fill with only recommended hydraulic
oil type as listed in Table 1.
4.
Hydraulic Valve —
Directional hydraulic control valve.
Controls the direction of hydraulic fluid supplied to the
dump cylinder and paddle shaft.
5.
Hydraulic Dump Cylinder —
When activated, this
cylinder will cause the mixing drum to rotate to the
dump position.
6.
Hydraulic Pump —
Supplies hydraulic fluid to the
hydraulic control valve.
7.
Hydraulic Dump Lever —
Pull lever
outward
to place
mixing drum in the dump position. Push lever
inward
to return mixing drum to the upright position.
8.
Hydraulic Paddle Blade Lever —
3-position lever.
Push
inward
for clockwise rotation of blades, pull
outward for counterclockwise rotation of blades. Place
in center position for no blade rotation (neutral).
9.
Hydraulic Oil Sight Gauge —
This gauge indicates
the level and temperature of the hydraulic oil. For
normal operation oil level should be visible at the 3/4
point on the sightglass.
10.
Strainer —
Filters out large particles and debris that
are harmful to the hydraulic system.
11.
Hydraulic Oil Filter —
10 micron hydraulic filter. Filters
out small particles that are harmful to the hydraulic
system.
