Safety Instructions - Hitachi VB 16Y Technical Data And Service Manual

11. SAFETY INSTRUCTIONS

Be particularly careful to ensure that the customer understands the following precautions which are listed on the
Handling Instructions and Caution Plates attached to the main body of each tool.
(1) Do not cut and/or bend any materials other than the rebars.
Avoid any work exceeding the maximum capacities of the unit described in the specifications. For example,
cutting or bending a hard rebar made of PC steel will not only damage the cutter but also there will be a fear of
the broken rebar fragments flying around. A slip clutch is built in the Model VB 16Y to protect the mechanism.
If the material with the diameter or quality beyond the capacity is processed, the slip clutch can sometimes
function. In such a case, stop processing immediately and check the material. When the slip clutch works, a
big slip noise occurs, but it is not a malfunction.
(2) Make absolutely sure that the cutter cover is closed when you do not carry
out the cutting work.
If the cover is kept open, the cutter can jam on foreign objects and cause
serious accidents.
(3) Reserve an extra length of at least 200 mm (8") on the bending length of the
rebar to be bent (Fig. 7).
If the extra length is not long enough, the rebar can come off during bending
operation, or it can break into fragments and scatter dangerously.
(4) Observe the specified number of rebars that can be bent or cut at one time.
<Bending>
Rebar of 10 mm (3/8") diameter: 3 pieces maximum
Rebar of 13 mm (1/2") diameter: 2 pieces maximum
Rebar of 16 mm (5/8") diameter: 1 piece
<Cutting>
Rebar of 10 mm (3/8") diameter: 2 pieces maximum
Rebar of 13 mm (1/2") diameter: 1 piece
Rebar of 16 mm (5/8") diameter: 1 piece
(5) Setting bending angles by setting dial
Even at the same dial setting position, the bending angle can sometimes differ if the diameter or hardness of
the rebar is different. Use the angle marks merely as a rough guide. (Refer to the Handling Instructions and
Caution Plates attached to the main body of each tool for details.) When replacing with the optional center
roller set, the bending angle may be slightly smaller than the set angle. Instruct the customers to set the
bending angle about 5 - 15˚ larger than the desired angle when replacing with the optional center roller (D38)
set or the center roller (D50) set.
