BLADE CUTTING DIRECTION 

shut off.    If so, push down on either emergency push 

buttons (I or H) to immediately stop all machine 

functions. 

- During the operation cycle, the hydraulic vise will 

automatically close on the work piece for a distance 

up to 8mm.    The hydraulic vise will then open 

maximum 8mm on end of operation.    Now it is ready 

for the next operation.    Therefore, it is not necessary 

to manually lock down the vise jaws on the work piece 

for every operation.    Allowing a gap of 4-5mm 

between jaws and the work piece will suffice. 

-The saw bow will return to the bow’s maximum height 

upon completion of operation. 

 

- In case of Emergency or problem during the 

operation cycle, press the emergency push button (H 

or I) down to shut off all functions. 

-To release the emergency push button (H or I), rotate 

the mushroom shaped button clock-wise.    The button 

will pop up and then the cutting cycle can be 

restarted. 

 

-The hydraulic flow control (G) will automatically 

shut-off after 5 minutes of non-operation. 

*Note: If the hydraulic flow control fails to activate, then 

switch (C), (D), and (F) cannot operate.    Indicator 

light (7) will blink if any are pressed, indicating that 

start switch (G) has failed to activate. 

-If the hand operation is selected and the foot pad is 

used, then the hand operation indicator light (4) will 

blink.    And vice versa, If the foot pad operation is 

selected and the hand switches are used, then the 

foot operation indicator light (5) will blink.    They 

indicate improper selection. 

-The appropriate indicator light will blink to indicate 

which part of the machine has gone out of order.   

1.    Indicator light 14 indicates the emergency button 

is pressed.    Indicator light 16 indicates the 

emergency button on foot pad is pressed. 

2.    Indicator light 13 indicates the band saw blade 

has broken. 

3.    Indicator light 10 indicates the blade cover is 

open. 

4.    Indicator light 12 indicates the motor has 

overloaded. 

5.    Indicator light 15 indicates the hydraulic motor 

has overloaded. 

6.    Indicator light 11 indicates the speed is not 

properly selected. 

-If the saw bow up/down switches are out of order then 

indicator lights 2 and 3 will blink at the same time.

 ADVICE ON USING YOUR 

BANDSAW 

 

4.1 Recommendations and advice for using the 
machine 

The machine has been designed to cut metal

 

building 

materials, with different shapes and profiles, used in 

workshops, turner's shops and general mechanical 

structural work. 

 

Only one operator is needed

 

to use the machine, that 

must stand as shown in the picture. 

 

 

- Before

 

starting

 

each

 

cutting

 

operation,

 

ensure

 

that

 

the

 

part

 

is firmly

 

clamped

 

in

 

the

 

vise

 

and

 

that

 

the

 

end

 

is

 

suitably

 

supported. 

- These

 

figures

 

below

 

show

 

examples

 

of

 

suitable

 

clamping

 

of

 

different section

 

bars,

 

bearing

 

in

 

mind

 

the

 

cutting

 

capacities

 

of

 

the

 

machine

 

in

 

order

 

to

 

achieve

 

good

 

efficiency

 

and

 

blade

 

durability. 

 

 

 

- Do

 

not

 

use

 

blades

 

of

 

a different

 

size

 

from

 

those

 

stated

 

in

 

the machine

 

specifications. 

- If

 

the

 

blade

 

gets

 

stuck

 

in

 

the

 

cut,

 

press the cycle start 

switch or emergency button to

 

switch

 

off

 

the

 

machine.

 

Open

 

the

 

vise

 

slowly,

 

remove

 

the

 

part

 

and

 

check

 

that

 

the

 

blade

 

or

 

its

 

teeth

 

are

 

not broken.

 

If

 

they

 

are

 

broken,

 

change

 

the

 

blade. 

- Check

 

saw

 

frame

 

return

 

spring

 

to

 

ensure

 

proper

 

balancing. 

- Before

 

carrying

 

out

 

any

 

repairs

 

on

 

the

 

machine,

 

consult

 

the dealer.
