CRANE OPERATION AND MAINTENANCE INSTRUCTIONS
HT25KX
SAFETY
Before operating this crane, read and understand these instructions, the 920612 Crane Safety and
Hazards Information Sheet, and review all safety & instruction labels on the crane.
CRANE INSPECTION
Before operating this crane, inspect for wear, damage, or oil leakage. After the wire rope has been run
out, check for wear, kinks, and broken strands. Check the hook and safety latch for damage. Correct
any problems before using the crane.
CAPACITY
Before operating this crane, review the capacity charts on the sides of the boom to relate the load to be
lifted to the boom length and angle. The boom angle is shown by a gravity arrow.
SNATCH BLOCK
If the load exceeds 2500 lbs. or reduced winching speed for better control of smaller loads is required,
use the snatch block to rig the crane for two part line operation.
CONTROLS
This crane is operated by a remote control pendant. The pendant should be unplugged and stored in a
compartment when the crane is not in use.
Before plugging the pendant in, inspect the plug, socket, cord, pendant head, and switches for damage.
Actuate all four switches both ways to verify that they all have the same feel and sound and that they
return to the center position.
PTO SYSTEM
Check the hydraulic fluid level in the PTO system reservoir. Engage PTO and set the engine idle speed
to provide a hydraulic flow rate per the PTO system instructions. A lower idle setting may be used for
more delicate spotting of loads if required.
CRANE OPERATION
Use "Winch Down" to release tension on the wire rope to unhook it from the storage tie down position.
Use "Boom Up" to elevate the boom from the boom rest position.
Avoid repeated rapid reversals of the control switches. This can cause the load to swing.
Check all control functions to see that they are working as described in the following section
CONTROL FUNCTIONS
WINCH "UP" and "DOWN" - Raises and lowers the load with the winch.
BOOM "UP" and "DOWN" - Raises and lowers the boom elevation angle. The boom elevates from 8
degrees below horizontal to 75 degrees above horizontal.
BOOM "OUT" and "IN" - Extends and retracts the boom. The boom hydraulic extension stroke is 6 ft.

ROTATION "L" and "R" - Controls the left and right direction of the crane rotation. The crane rotation
is limited to 400 degrees.
POWER (Non Proportional Systems with Engine Controls) - Energizes safety shutoff valve. See
page 22328 for detailed operating instructions and warnings.
TRIGGER (Proportional Systems Only) - Varies the flow rate delivered to the crane valve. The
farther the trigger is pulled, the faster the selected crane function operates.
OVERLOAD SENSING SYSTEM
This crane is equipped with an Overload Sensing System. If the capacity of the crane is exceeded,
the "Winch Up", "Boom Down", and "Boom Out" functions will be shut down. The "Winch Down",
"Boom Up", and "Boom In" functions will continue to operate and can be used to relieve the overload
condition. The "Rotation" function also will continue to operate.
The Overload system is inoperative if the boom elevation is at the bottom or top limit of travel. To
relieve this condition, raise or lower the boom slightly before lifting the load.
TWO-BLOCK SENSING SYSTEM
This crane is equipped with an anti two-block device that is mounted at the tip of the boom. If the
snatch block/overhaul weight contacts the device the "Winch Up", "Boom Down", and "Boom Out"
functions are disabled. The "Winch Down", "Boom Up", and "Boom In" functions will continue to
operate and can be used to relieve the two-block condition. Refer to Drawing 19050 for parts
breakdown and configuration information.
MANUAL TELESCOPIC BOOM
The 10 to 20 ft. boom has a 4 ft. manual telescoping section in addition to the 6 ft. power extension.
A pin locks the manual extension into either the extended or retracted position.
TRUCK SETUP & OUTRIGGERS
1. The truck should be parked on ground that is as level and as firm as possible when using the
crane.
2. The center of the crane should be positioned close enough to the job so that it can be operated at
a reach that puts the load within the rated capacity of the crane.
3. Set the vehicle parking brake and put the vehicle transmission in "park" if it is an automatic.
4. Deploy the outriggers to help stabilize the vehicle against rocking or overturning when lifting with
the crane.
PREPARATION FOR TRAVEL
1. Return the outriggers to the stowed position. Install and secure all pins.
2. Stow the crane boom in the boom support.
3. Hook the winch line to the tie down point on the boom and apply light tension.
4. Disengage the PTO pump and idle speed control.
5. Unplug the control pendant and store in a body compartment or the cab.
