CONTROLS AND OPERATING PROCEDURES OPERATOR MANUAL 600H SERIES
Electric Shift Control
Full torque electric shift PTO’s are controlled by a switch. To
operate, disengage the clutch, shift to fourth or fifth gear, and
operate the switch down to engage the PTO or up to
disengage the PTO. Return the gear shift to neutral and
engage the clutch.
Power Shift Control
If the vehicles equipped with automatic transmission, the
power take-off must be engaged with the engine at idle.
Refer to transmission manufacturers instructions for special
procedures.
Park Brake
The truck brake must be firmly set before leaving cab to
begin operation. If the ground surface is icy or slick or is
sloped, chock the wheel.
CRANE CONTROLS
The unit is equipped two operator stations: one on the
drivers side and one on the passengers side of the truck
(Figure 3-1). Decals next to the controls indicate which
direction to actuate the controls. Each station provides
control of boom rotation, boom elevation, boom extension,
hoist, outriggers and engine speed. An engine emergency
stop switch shuts down the truck engine. All control handles
except the outrigger controls are positioned in the same
order at both control stations.
Boom Rotation
The 600H series crane is not a continuos rotation machine. A
mechanical rotation stop pulls the turn control lever to the
neutral position when the boom reaches over the front
center. This prevents damage to the hydraulic hoses due to
twisting.
On rear mounted cranes, the boom is over the front when in
the boom rest. Rotate the boom to the right over the
passenger side of the truck when stowing and unstowing the
jib or rigging the hook block to keep from activating the
rotation stop.
Swing Speed Adjustment
Located on swing motor inside frame. Turn knob in to
increase the maximum speed. Turn knob out to decrease the
maximum speed.
Boom
Position the control lever to DOWN to lower the boom and UP
to raise the boom.
Boom Telescope
Position the control lever to OUT to extend the boom and IN
to retract the boom.
