b. Exceptions ensuring equivalent protection are allowed, if approved by the administrative or regulatory
authority in writing.
c. Install durable signs at the operator's station and on the outside of the crane, warning that electrocution or
serious bodily injury may occur if the Table 1. Safe Operating Distance limits aren't adhered to.

4.7 PREPARING THE CRANE FOR OPERATION

1. Ensure the manual has been thoroughly read by all crane operating and maintenance personnel and supervisors.
2. Perform a routine inspection of the crane before operation each day. Correct any defects immediately.
3. At the job site, position the vehicle so the crane can reach the load within the rated capacity (centerline of rotation
to hoist hook).
4. Keep the vehicle as level as possible during operation.
are disabled.
5. Allow the vehicle engine to warm up before operation.
6. For Auto Crane units using only electric operation:
a. Engage the emergency brake,
b. Leave the ignition on with the transmission in neutral (or park for automatic transmissions),
c. Activate any crane power switches.
7. For Auto Crane units using electric and hydraulic operation:
a. Engage the emergency brake,
b. Place the transmission in neutral,
c. Press the clutch in,
d. Activate PTO (Power Take Off),
e. Release the clutch,
f. Allow sufficient time for the hydraulic fluid to warm up,
g. Set the throttle control to the proper engine speed.
8. For all outrigger usage:
a. Always extend the outriggers from the vehicle to the ground before crane operation. Ensure they are
firmly positioned on solid ground.
b. Stand clear of outriggers while being extended.
c. If a curb or other object prevents the outrigger from begin fully extended, shorten the bearing or fulcrum
point and reduce the maximum load accordingly.
d. If an outrigger will not reach the ground because of holes or grades, block up the outrigger pad to provide
level and firm support to the vehicle.
e. If working in soft ground, use wide pads under the outrigger feet to prevent sinking.
f. Always store the outriggers before transportation.
i. For Auto Crane units with Manual Outriggers:
ii. For Auto Crane units with Hydraulic Outriggers:
9. Remove the remote control from the cab or storage area. Power the remote control on. Detach the hook from the
dead man.
10. The crane is now ready for operation.

DURING OPERATION

1. Always boom up before rotating so the boom will clear the boom support.
2. Always maintain clearance between the boom crown and the traveling block or hook hoist during boom extension.
3. Always observe all relevant safe policies and procedures during crane operation.
4.
Always use slow and smooth movements with the crane to avoid causing the load to swing like a pendulum.
At a 10° slope, all crane functions are limited to 50% speed. At a 15° slope, all crane functions At a 10° slope, all crane functions are limited to 50% speed. At a 15° slope, all crane functions
1. Pull the lock pins to release the jackleg or drop down outrigger. Move to the outermost
lock position.
2. Ensure lock pins are reinstalled properly.
3. Lower the Outrigger pad to firm ground and adjust the foot to remove slack.
1. Shift the diverter valve to the Outrigger position.
2. Extend the Outriggers to their horizontal limit.
3. Extend the Outriggers vertically until they make solid contact with the ground with the
ground and the truck is approximately level side-to-side.
4. With the Outriggers properly positioned, return the diverter valve to the Crane position.
