7.2. Failures - Potential Causes and Remedies

Failure
Saw blade feed cannot start
The motor is on, but the saw blade
is not moving
Red light on the control panel
Irregular cooling
Vibration during cutting
Broken teeth stuck in the cutting
channel in the workpiece
The blade cuts under
Saw blade cracking between teeth
Saw blade cracking on the face
The feed to cut is not constant,
sinks
The arm descends even when
the relief valve is closed
The arm does not ascend
Possible cause
• The power switch is off
• The TOTAL STOP button is locked.
• The protective overcurrent relay is off
• The vice is not clamped
• The control board fuse is burnt
• The saw arm is in the lowest position, the limit
switch is pressed
• The saw arm is not in upper position
when in S.A.F. mode
• The saw blade slips on the running wheel
• Broken blade
• Other fault in the gearbox
• Coolant used up
• The coolant tank and/or supply pipes or the
ball valves are contaminated
• Broken pump
• The feed to cut occurs within a non-desirable
range
• Wrong selection of saw blade tooth size
• Incorrectly adjusted guide heads,
hardened steel blade guides, bearings
• Incorrectly clamped material
• Blunt saw blade
• Wrong selection of saw blade tooth size
• Feed to cut is too quick
• The blade slid under guide bearings
• Clearance between hardened steel blade guides
• The workpiece is not placed parallel with
the vice loading surface
• Wrong selection of saw blade tooth size
• Feed to cut is too quick
• Incorrectly adjusted or damaged guidance
through heads (blade guids, bearings)
• The moving guide head is too far from the
workpiece
• Insufficient cooling
• Incorrectly clamped workpiece while cutting
• Saw blade incorrectly placed on wheels
(runs into the fitting)
• Wrong selection of saw blade tooth size
• Feed to cut is too quick
• Incorrectly adjusted or damaged guidance
through heads (blade guides, bearings)
• The moving guide head is too far from
the workpiece
• Not enough oil in hydraulics
• Loosened M4 screw on control valve's wheel -
turns loosely
• Valve seat is worn out
• Cylinder sealing is worn out
• Valve failure (impurities)
• The arm uplift switch is set to 0
• The power switch is off
• The TOTAL STOP button is locked
Remedy
• Turn on the power switch
• Unlock the TOTAL STOP button
• Check motor protective switch
• Clamp the vice
• Replace the fuse
• The saw arm must be raised when the saw blade
starts
• The saw arm must be in the upper position
when in automatic mode
• Tension the blade properly as specified in section 4.7.
• Replace it (see section 4.7.)
• Call the service technician
• Control panel describes the type of fault
• Check the coolant
• Clean the coolant tank and supply pipes
• Replace the pump
• Set 5% less/more feed to cut
• Check the tooth size
• Adjust it, see section 4.8.
• Check workpiece clamping
• Do not cut into an old cutting channel with a new
blade! Otherwise you damage the new blade
with the first
• Replace the blade
• Check the tooth size, see section 8.2.
• Adjust the feed
• Insert the blade properly as specified in section 4.7.
• Adjust it, see section 4.8.
Align the roller conveyor, check workpiece clamping
• Check the tooth size, see section 8.2.
• Adjust the feed
• Adjust (see section 4.8.) or replace them
• Move it closer, see section 4.5.
• Increase the coolant supply
• Clamp the workpiece properly
• Check, see section 4.7.
• Check the tooth size, see section 8.2.
• Adjust the feed
• Adjust (see section 4.8.) or replace them
• Move it closer, see section 4.5.
• Call the authorised service centre
• Tighten it
• Tighten M4 lock screw, turn wheel approx. 10°
to the left and tighten
• Call the authorised service centre
• Call the authorised service centre
• Switch it to 1
• Turn on the power switch
• Unlock the TOTAL STOP button
