when overload occurs.
“Electrical type Safety and Control devices”
⚫When carrying out an operation test or making a periodic inspection, make sure to verify
that it functions properly as a protection device.
⚫Follow the instruction manual when carrying out megger testing because most electrical
devices have certain requirements for megger testing.
⚫Check the operation of the device periodically so that it can be sure to function properly
when overloaded occurs.

carrying out maintenance and inspections. Take the necessary measures to ensure the
power is not turned back on.
3) Follow the instruction manual.
4) Wire according to the technical standards of Electrical Installation and company
regulations. Take note of the cautions in this manual which explain installation
direction, clearance and environmental conditions. Make sure to ground the device to
prevent electrical shock and to improve noise resistance.

otherwise an accident resulting in death, serious injury or damage to the equipment may
occur due to a falling accident.
Death or serious injury may result from product misuse due to not
following the instructions.

CAUTION
“Mechanical type Safety and Control devices”
⚫The strength of the equipment should be designed to withstand the load or rotational force
when the device is activated due to overload.
⚫Wear damage may occur depending on the number and frequency of activations. Following
the manual, check the functions and operations periodically. If something is not functioning
properly, contact the distributor for repair.
“Electrical type Safety and Control devices”
⚫Consumable parts (tantalum electrolytic capacitors, relays, etc.) are built-in the products.
Using the manual, periodically check the functions and operation of the device. If it is not
functioning properly, contact the distributor for repair.
⚫Do not use the device in a corrosive gas environment. Sulphidizing gases (SO2, H2S) can
especially corrode the copper and copper alloy used on PCBs and parts, and cause a
malfunction.
“Common”
⚫Read the instruction manual carefully, and use the product properly. In case the instruction
manual is not available, request one from the distributor where you purchased the product,
or our sales office with the product name and model number.
⚫Deliver this instruction manual to the final customer who uses the TSUBAKIMOTO CHAIN
product.
Minor or moderate injury, as well as damage to the product may
result from product misuse due to not following the instructions.

2. INSTALLATION
２－１．Installation to the axis
A Bore diameter tolerance of h6 or h7 for installing the Shock Guard to the shaft is
recommended. Use a JIS 1301-1996（New JIS standards）parallel key. Allow some
clearance between the top of the key and keyway.
When installing the cam actuating plate to the shaft, tighten bolts in three places.（For
the key, 1 place; for the shaft, 2 places）
When mounting the Shock Guard to the end face of the shaft, depending on the
installation method, the cam actuating plate set screws cannot be used. In this case use
the tap holes on the mounting seat side.
Set screws for these tap holes are not included, so use bolts with a length that fits the
bore diameter. (Table 2) Take care to ensure that the head of the set screws do not come
out from the outer diameter of the camshaft.
If the head of the screws come out, they will interfere with the inner diameter and lateral
side of the mounting seats when the Shock Guard trips.
If during operation there is a chance vibration will cause the screws to loosen, apply
Loctite 242 or an equivalent for anti-loosening.
