Air Line Lubricator
Hoists may be operated without an air line lubricator. If a lubricator is used, use one having an inlet and outlet at least as
large as the inlet on the hoist motor. Install the air line lubricator as close to the air inlet on the hoist motor as possible.
• Lubricator must be located no more than 3 m from the hoist motor.
• Shut off air supply before filling air line lubricator.
The air line lubricator should be replenished daily and set to provide lubrication at a minimum rate of 1 to 3 drops per
minute adjusted at maximum hoist speed, of SAE 30W ISO VG100 oil.
Air Line Filter
It is recommended that an air line strainer/filter be installed as close as practical to the motor air inlet port to prevent dirt
from entering the motor. The strainer/filter should provide 20 micron filtration and include a moisture trap. Clean the
strainer/filter monthly to maintain its operating efficiency.
Moisture in Air Lines
Moisture that reaches the air motor through the supply lines is the chief factor in determining the length of time between
service overhauls. Moisture traps can help to eliminate moisture. Other methods, such as an air receiver which collects
moisture before it reaches the motor or an aftercooler at the compressor that cools the air prior to distribution through the
supply lines, are also helpful.
Overload Device
An overload device is required on all hoists with a rated capacity of over 1 metric ton used for lifting applications. The
overload device is integrated into the hoist air motor and prevents the hoist from lifting a load greater than the overload
value listed in the specifications chart. If an overload is detected, inlet supply air is stopped and the hoist will not operate.
If the overload device is activated the load must be lowered and reduced. Alternative methods should be used to
accomplish the task. To lower the load reset the hoist by pressing the "ON" button of the emergency stop device and press
the hoist control lever to lower.
Storing the Hoist
1. Always store the hoist in a no load condition.
2. Wipe off all dirt and water.
3. Oil the load chain, hook pins and hook latch.
4. Place in a dry location.
5. Plug hoist air inlet port.
6. Before returning hoist to service follow instructions for Hoists not in Regular Service in the "INSPECTION"
section.
The four most important aspects of hoist operation are:
1. Follow all safety instructions when operating hoist.
2. Allow only people instructed in safety and operation on this product to operate hoist.
3. Subject each hoist to a regular inspection and maintenance as recommended by the manufacturer.
4. Be aware of the hoist capacity and weight of load at all times.
Operators must be physically competent. Operators should have no health condition which might affect their ability to
react, and they must have good hearing, vision and depth perception. The hoist operator must be carefully instructed in his
duties and must understand the operation of the hoist, including a study of the manufacturer's literature. The operator must
be aware of proper methods of hitching loads and should have a good attitude regarding safety. It is the operator's
responsibility to refuse to operate the hoist under unsafe conditions.
Initial Operating Checks
Hoists are tested for proper operation prior to leaving the factory. Before the hoist is placed into service the following
initial operating checks should be performed.
1. After installation of trolley mounted hoists, check to ensure the hoist is centered below the trolley.
2. Check for air leaks in the supply hose and fittings to pendant, and from pendant to manifold.
3. When first running the hoist or trolley motors a small amount of, non-detergent, light oil should be injected into the
inlet connection to allow good lubrication.
