Preface
Congratulations on your CRANE Lever Block purchase.
The CRANE Lever Block you have chosen, is a top quality & heavy
duty hoist, designed to retain its operational features under normal
operating conditions. In order to achieve years of satisfactory
service from your CRANE Lever Block regular maintenance and
lubrication should be applied.
Prior to operation, please read all the contents contained within this
manual. At all times only competent and experienced personnel
should operate, install or maintain this hoist. Failure to comply with
the instructions contained within this manual can result in both
physical and/or property damage.
In keeping with statutory requirements, and best use for your
CRANE Lever Block we recommended a periodic maintenance check
every 12 months.
Initial Set Up Check
Your CRANE Lever Block has been tested, and conforms to
Australian Standard AS1418.2 - 1997
On completion of installation, but prior to your CRANE Lever
Block being put into regular service, the following procedures
should be carried out:
1. Check that all joints and fasteners are tight and secure.
2. Check operation of hoist brake, under light load and full load
conditions.
3. Operate the hoist with both no load and full load, and check
that the operation is smooth at all times.

Instructions
Principle and Operation of Free Chain Adjusting System -
Free Chain Adjusting Principle.
WARNING IMPROPER use of chain lever blocks could result
in death or serious injury. To avoid these hazards: please read &
follow the instructions in this owners manual.
WARNING NEVER operate the free chain adjusting device while
load is applied to chain lever block.
WARNING NEVER touch the free knob during lifting or lowering
of the load.
Note: The break is engaged automatically
during lowering or lifting of the load. Free
chain adjusting is achieved by releasing the
brake during no-load.
Step Action
1. Set the charge-over knob to “N”. The change-over knob is
located under the free knob on the hand lever.
2. Rotate the “Free” knob slightly in desired direction.
3. Pull the load chain to move the hook to the desired location.
4. By “setting” the change-over knob to “Up” or “Down” , this
will reset the break and allow the hoist to be operated with
the hand lever.
Method
Principle of Lifting and Lowering Operation - Lifting and
Lowering Principle
By setting the change-over knob to “UP” or “DOWN”, and operating
the lever, the female thread and the change-over pawl inside the
hoist engage and the female thread rotates in either the lifting
or lowering direction. The brake works instantly after the lever
operation stops and holds the load.
Lifting and Lowering
Select direction of movement and ratchet hand lever back and
forth, see below:
NOTE 1: If hand lever movement does not produce lifting, pull
down the load chain while ratcheting until slack is removed.
NOTE 2: PRE-LOAD is the minimum load that must be applied to
the lever block before the braking system activates. The PRE-LOAD
on the CRANE Lever block is set approximately 3% of the W.L.L.
(Working Load Limit) of the particular Lever Block. eg. (800Kg lever
hoist 24kg), (1600kg lever hoist 48kg), (3200kg lever hoist 96kg),
(6300kg lever hoist 189kg), (9000kg lever hoist 270kg).

Safety Procedures
The following Safety section should form part of the safety rules
for any plant where any hoist or other lifting equipment is being
used, serviced or repaired.
Any person(s) operating the hoist should read and observe
the following safety instructions and the instructions in the
Operating section, to avoid operating hazards.
Always Check for any cracks or wear signs on the unit before use
and ensure you are working in a safe environment before use.
1. DO NOT load beyond the rated capacity.
2. DO NOT heat treat and DO NOT weld any part of the
lever block, especially the load chain.
3. DO NOT leave a load on the lever block unattended.
4. DO NOT shock load lever block, chain or hook.
5. DO NOT operate the lever block unless it is rigged to
pull in a straight line from hook to hook, and the frame is
allowed to freely swivel on the upper hook.
6. DO NOT hold the load chain in a loaded state while
operating the lever block as serious injury may occur if
the brake did not operate properly.
7. DO NOT wrap the load chain around the load and hook
onto itself as a choker chain, or bring the load in contact
with the lever block.
8. DO NOT use this lever block for lifting or moving people,
or lifting loads over people.
9. DO NOT take up the load chain to the point where the
end ring or lower hook becomes jammed against the
frame.
10. DO NOT use an extension pipe or cheater bar to apply
more pressure to the lever handle.
11. DO NOT Repair unless you are fully qualified to do so.
12. Do Not allow your attention to being diverted whilst
lifting the load.

Care in Use
1. Always examine the hoist carefully before use - your life may
be at stake. Look for cracks or damage, particularly with hooks
and load chain.
2. Keep load chain clean and oiled to prevent undue damage or
wear. When in use, avoid dragging the load chain through dirt
or mud.
3. When the hoist is used outdoors or in a corrosive environment,
ensure that it is regularly and adequately lubricated.
4. Do not operate the hoist if you do not have a clear view of the
bottom hook and the load.
WARNING
If a load hook has been distorted, due to an overload on the
hoist, then the hoist lifting unit will also be damaged. A hoist
which has been overloaded must be withdrawn from service
immediately.
