WARNING; Do not touch the hoist after operation.
・ After operating the hoist, do not touch the hoist. After operation, the hoist may become hot. Please
let the hoist cool before touching.
WARNING; Do not use the limiter to stop the hoist all the time.
・ This mechanism is a safety device. The limiter for over lifting and over lowering will operate
continuously using this device may lead to an accident and it is not recommended to use it
continuously.
WARNING; Do not over look the load limiter setting and confirm before
using the hoist.
・ A load limiter is equipped within the hoist but please understand that this device is the final
emergency measure to stop the hoist. During actual operation, it is necessary that the load is
within the rated load of the hoist before it is used.
WARNING; The load limiter must be adjusted when the air pressure
changes.
・ The load limiter needs to be adjusted according to the air pressure being used. At the factory it
has been set at 125% of the rated load at 0.6 MPa. If the hoist will be used above this air pressure,
referring to the section of “ how to adjust the load limiter “ must be refereed. Also, depending on
the piping and hose size and length the setting may change. If the setting adjustment is not made
the hoist may stop below the rated capacity. It is dangerous to perform lifting of a load above 125%
of the rated load.
WARNING; Use one hoist when lifting.
・ When lifting for more than 2 hoists, balance becomes a factor and one hoist may be stronger and
this type of operation can become dangerous.

WARNING; When using 2-load suspension type, be sure to use sling chain or
wire style equipment when lifting.
・ When lifting a load using an under hook 2-load suspension type(TMH-6000-2), be sure to use a
sling chain or wire style equipment and be sure to lift the center of the load with under hook in
vertical position. Please do not tilt or drag the under hook when lifting.
If the load is lifted wrong way, there is a possibility that under hook block will tilt or the chain will
loosen. This may allow the limit spring on the chain to enter the chain entrance in the under
hook and jam, or the chain can get hung up and may lead to chain breakage or an accident.
When lifting the load, make sure the chain can move smoothly into the under hook block entry
holes.
WARNING; Lubrication for the chain.
・Please apply lubrication oil to the lifting chain certainly. If there is no oil on the chain, chain will be
worn out soon. This may lead to dropping of the load and personal injury due to breaking of the
chain and it is very dangerous.
Lubricate chain links and sprockets contacting part on both Load Sheave and Free Chain Wheel
with Fricttle 2 (liquid type, Rix Corporation product) in every 300 cycles. Make sure to lubricate
chain when it is dry even before reaching 300 cycles. Viscogen KL300 (Castrol .Ltd product) can be
used instead of Fricttle 2 in a light use, less than 30 cycles a day. In this case lubricate chain
every 30 cycles. Spray type is recommended for easy lubricating.
CAUTION; Do not pull or use the hoist side ways.
・ The hoist was designed to be used in the vertical direction. Using the hoist in the horizontal
direction is not recommended and may result in an accident or premature wear of parts.
CAUTION; Do not suddenly change the direction of the hoist.
・ Suddenly changing the direction of the hoist will shock certain areas of the hoist and may cause
breakage of parts or lead to an accident.
CAUTION; Do not pull on the pendant hose or cords when trying to
move the hoist.
・ This will lead to damage to the hose and may cause the hoist to malfunction.

CAUTION; Use the hoist indoors.
・ Using the hoist outside may become effected by rain and moisture allowing the hoist to rust
leading to malfunction. Do not use the hoist outdoors.
CAUTION; Storage must be considered carefully.
・ Store the hoist away from children in a dry area. When storing the hoist for a longer period of time,
to prevent internal rust, apply 3 cc of lubrication into the air hose and operate the hoist for 3-4 sec.
CAUTION; Make sure the correct air pressure is used with the hoist.
・ Operating air pressure is 0.4～0.6Mpa ≪Recommended air pressure 0.6MPa≫
Operating at air pressures above 0.4～0.6Mpa will effect the durability, performance and safety
of the hoist. As a result, it is important to consider the pressure for the air compressor, volume
and piping aspects to operate the hoist at its best level.
※ Please note the air pressures stated above are actual operating air pressures and not the air
pressure when the hoist is not operating, which is normally slightly lower. As a result, always
check the air pressure when the air hoist is operating.
CAUTION; Operate the hoist in the correct ambient temperature.
・ The recommended ambient temperature for the hoist is in the range of -20℃～70℃.
≪Recommended20℃≫
Operating the hoist out of the above temperature range will affect the durability, performance and
safety of the hoist.
CAUTION; Air maintenance is important.
・ Always use a air filter, regulator and lubricator (line oiler) near the hoist
The size we recommend is a size larger than the actual piping size and for the air regulator we
recommend the pilot type regulator. If a pilot style regulator is not available, we recommend a
regulator one size larger than the standard size. (To keep the performance level for the hoist)
With regards to the lubricator (line oiler), we recommend a flow of 15-20 drops/min
（approximately 0.3-0.4cc） of lubrication.
If air maintenance is not performed properly, this will lead to rust, malfunctioning and premature
wear of the internal parts, and this may result in personal injury.

（７）Preparation before operation
１． Preparation of the compressor and drain removal.
・Method of selection; ( Air Consumption for each hoist is shown on Page 13)
( Air consumption × 10 ) × Hoist Quantity ≦ Compressor Horse Power
・Method of drain removal;
Rust will develop leading to the cause of trouble if the drain is not removed from the compressor.
Remove the drain at the bottom of the air tank on your compressor. Remove excess water and oil.
Supply clean dry air to the hoist. (Refer to the compressor manual for details）
２． Piping
Refer to the diagram below for piping or installation. The main and secondary pipes should be larger
than the air hoist hose size. It the main or secondary pipe is smaller in diameter or too long, you will
experience pressure drop and this will reduce the performance of your hoist.
CAUTION; Always install an Air Filter, regulator and lubricator (Line Oiler)
near the hoist.
・ Always use an air filter, regulator and lubricator (line oiler) near the hoist
The size we recommend is a size larger than the actual piping size and for the air regulator we
recommend the pilot type regulator. If a pilot style regulator is not available, we recommend a
regulator one size larger than the standard size. (To keep the performance level for the hoist)
With regards to the lubricator (line oiler), we recommend a flow of 15-20 drops/min. of lubrication.
If air maintenance is not performed properly, this will lead to rust, malfunctioning and premature
wear of the internal parts, and this may result in personal injury.

３． Preparation of the Air Hose
WARNING; Do not use Quick Coupler for connection.
・ Quick Coupler restricts air flow too much. This leads to significant degradation of the hoist
performance and to trouble on brake part.
・Size of Hose： The hose size for this hoist is ID 38mm or larger.
Prepare suitable hose band for hose size.
・Length of Hose：
IMPORTANT; We recommend to keep the hose length within 10 meters.
・If the hose is too long, the air pressure will drop at the hoist. In order to prevent the pressure
drop, use a hose with ID larger than 50mm.
Please refer to the following chart showing the relationship between air flow and pressure
drop for a 10 meter long hose.
0.4 0.0066 0.0117 0.0182 0.0263 0.0358

※The chart information shows the pressure reduction at each Air Pressure at free flow. The pressure drop has been
calculated by subtracting the pressure from the inlet of the hose to the outlet port.
※If the hose length is longer than 10 meters, the relationship of the pressure drop if proportional to the extended
length. As a result, if the hose length is 20 meters, you would multiply the above chart numbers by 2.
４． Check the strength of the beam before installing the hoist.
WARNING; Before installing the hoist to the beam make sure the safety
factor is met.
・ Before installing the Air hoist to the beam, make sure the rated load for the beam exceeds the
rated load for the air hoist with the proper safety factor. If the rated load of the beam does not
exceed the rated load of the air hoist, please do not install the air hoist to this location.
