NOTE: You must read and understand the warnings and
basic safety rules, found in section 2 of this
manual, before performing any operation or
maintenance procedures.

the engine manual furnished with this crane.
Inspections
Inspecting the Anti-Two-Blocking System
Test the anti-two-block system daily before beginning
operation to make sure it is functioning properly.
Raise the drop block until it hits the anti-two-blocking bracket
under the boom head. An alarm should sound and the
raising of the hoist block should stop.
Lower the hoist block and the alarm will stop.
If there is a malfunction in the system, DO NOT operate the
crane. Have the malfunction corrected.
Inspect the Wire Rope
Each day before beginning operation, visually inspect the
wire rope for damage. Refer to 50 Hour Maintenance for
examples of damage that can be visually inspected for. If any
damage is found, do not operate the crane. The wire rope
must be replaced with a new rope before operation can
resume.
Inspecting Reeving, Clamps and Connections
Each day before beginning operation, inspect for correct
reeving of the boom and drop block.
Inspect the terminal ends of the wire rope for damaged parts,
loose clamps or wrong installation.
Do not operate the crane if any of the above are found. Only
after correcting the problem should the crane be put back in
service.
Inspecting the Lifting Hook
Daily before beginning operation, inspect the lifting hook for
damage; cracks, deformation, loose retaining hardware, etc.
If any damage is found, DO NOT operate the crane until the
damage is repaired.
Inspecting All Safety Devices
Daily before beginning operation, check all safety devices for
proper operation. Examples of safety devices include,
backup alarms, horn and beacon lights.
If any is found to be malfunctioning, correct the problem
before placing the crane in service.
Checking Controls Operation
Each control should be checked for proper operation after
the above inspections have been completed. Do not place
the crane in service if any control is not functioning properly.
Component/System Checks
Checking Fuel Level
Check the fuel supply daily before operation. Turn the
ignition key to the ON position and view the fuel gauge on the
instrument panel. If necessary, fill the tank with
recommended fuel.
Engine fuel is flammable and can cause a fire and/or
explosion. Avoid personal injury or death by keeping sparks,
open flames, and smoking materials away from the crane
and fuel during refueling or fuel system servicing. Know the
location of the fire extinguishers on the job site and how to
use them.
