TROUBLE SHOOTING GUIDE
Most problems which may occur have one of the relatively simple solutions which appear in this section. If
the solution is not found here, contact the Hyd-Mech Distributor from whom you purchased your bandsaw. They
have trained field service personnel who will be able to rectify the problem.
NOTES:
1) IF THE BLADE IS RUNNING COUNTER CLOCKWISE OR THE HYDRAULIC PUMP IS NOISY
SHUT THE SAW DOWN IMMEDIATELY!
2) IF THE DRIVE MOTOR IS TO BE REPLACED, IT MUST BE REPLACED WITH A NON-VENTED
MOTOR TO PREVENT COOLANT LEAKING INTO THE MOTOR.
3) THE HEAD SHOULD BE SWUNG TO 45
O
LEFT OR RIGHT BEFORE ANY HYDRAULIC SERVICE
IS PERFORMED TO PREVENT THE HEAD FROM MOVING UNEXPECTEDLY.
ELECTRICAL TROUBLESHOOTING
SOLUTION
1a) Depress Blade Motor Overload Reset
Button.
1b) Replace Fuse with 8 AMP 250 V AG
type. Repeated Fuse Blow-outs indicates
an internal wiring fault.
1c) Remount the blade.
1d) Check functionality of safety interlock
switches.
2a) Stop Immediately. Reverse any two of
three phase connections.
2b) Stop Immediately and add hydraulic oil
until the correct level is present.
2c) Stop Immediately and check for the
adjustment required.
3a - 3b) The solution to this problem is
handled best by a qualified electrical
technician.
4) Replace the component that is
inoperative. Test
voltage levels at switch.
5a) Interupt main supply to machine for
two to three minutes.
5b) Check blade motor line fuses.
CAUSE
1a)Motor overload has tripped.
1b)Control cicuit has blown.
1c)Check blade breakage limit
switch.
1d) Check that doors and gaurd
are closed.
2a)Check system pressure gauge.
Wrong phase order if no pressure.
2b)If pump runs noisily then
check the hydraulic oil level at
gauge.
2c)Check the pump/motor
coupling for separation.
3a)Check pilots on valves. If
pilot fails to light, then check
electrical system.
3b) If pilot lights but output fails
the coil may be bad. Check dirt in
valve spool.
4) The switch or pushbutton
contact assembly is defective.
5a) Check for red fault light at
VFD.
5b) Red fault light on VFD is
not on.
PROBLEMS
1) Saw will not start at all.
2) Saw will start, but no
hydraulic functions
respond.
3) Functions will not
respond to manual controls.
4) An operator control will not
respond.
5) Hydraulics run but blade will
not start.
