bracket and is contacting the over wind valve, move the AUGER LATCH lever
into the CLOSE position and hold until the latch is completely closed. Return the
AUGER ROTATION lever to the neutral position and the auger flighting shaft will
rest on the closed stow bar. Do not continue rotating the auger if contact with
the over wind valve does not stop rotation. Damage may occur to the wind-
up rope or stow bracket, which could cause the auger to drop. Visually
check the complete auger system after it is stowed to ensure that the auger is
properly locked in the stow position and that all ropes, pins, and keepers are
properly installed prior to machine shutdown
5. Refer to the “Shut Down and Preparing for Road Travel” Section in the Owner’s
Manual when stowing the machine after use.
Machine Use with Auger Stowed
1. Refer to normal “Operating Procedures” as outlined in the Operation Section of
the Owner’s Manual to set the crane up properly
2. Inspect the auger stow mechanism to ensure all ropes, pins and keepers are in
place so that the auger is securely stowed
3. Before lifting any loads with the crane, refer to the “Capacity Deduction” decal
located at the operator’s station. With the auger stowed on the side of the boom,
each maximum capacity load showed on the load chart must be reduced by the
amount shown on this decal
Digger System Description
The Digger System hydraulic schematic is provided in the specifications section
of this manual. The hydraulic circuit is explained below:
Digger Circuit
The required flow for the digger is approximately 55 GPM for optimum
