FLOOR & SEAT AREA
Throttle Pedal:
This is right-foot operated and con-
trols the engine RPM to match increased power
requirements. Pushing down on the pedal increases the
RPM. Letting up on the pedal decreases RPM.
Service Brake Pedal:
Depressing this pedal hydrauli-
cally activates the internal braking mechanism of the
front and rear axles to all four wheels.
Brake Fluid Reservoir:
The reservoir is located under
the hinged seat mounting section. With rear bolts
removed, this section may be tilted forward to check
fluid level.
Seat Positioning:
The seat is mounted on rails for for-
ward or backward repositioning to accommodate oper-
ator’s size and comfort. A spring-loaded latch handle
under the front of the seat activates the adjustment
mechanism.
RIGHT SIDE PANEL
These controls and indicators are used to position the
frame, boom, and attachment. Graphic symbols on the
side panel illustrate the control actions.
Frame Level Joystick:
This may be tilted slowly 10
o
to the left or right to level the frame and boom in rela-
tion to the ground. Position the lever to the left to tilt to
the left. Position the lever to the right to tilt to the right.
Bubble Indicator:
Located in front of the operator on
the ROPS upper cross tube, movement of the bubble
shows when the frame is at level position relative to
slopping ground surface.
The boom inner section nose has an attachment carry-
ing device feature called Dynattach
®
system. This pro-
vides the operator with a convenient means of utilizing
optional attachment tools. Refer to the OPERATION
& ADJUSTMENTS chapter for changing attachment
tools procedure.
Once the operator tilts the attachment tool to a desired
angle, that angle will be maintained as the boom is
raised or lowered, extended or retracted, until a new
angle is desired.
To tilt the attachment tool, move the joystick back to
tilt up. To tilt the attachment tool down, move the joy-
stick forward.
Boom Lift/Extend Joystick:
This machine has a
hydraulic type boom with telescopic sections. The sec-
tions extend by means of a hydraulic cylinder and
chain system inside the boom, sequenced for uniform
extension of each section.
To EXTEND the boom, move the joystick RIGHT. To
RETRACT the boom, move the joystick LEFT. To
RAISE the boom, move the joystick REARWARD. To
LOWER the boom, move the joystick FORWARD.
