CLEANLINESS
The heavy-duty design should endure heavy operating conditions and provide the customer with awless machine perfor-
mance. To extend good performance some care is required especially where cleanliness is concerned.
The following areas should be kept clean:
• Control console free of dirt and grease
• Door charts free of dirt and grease
• Wheel boxes free of chips
• Blade guides free of chips
• Out-feed tables free of chips
• A large chip build-up should be avoided in the base of the saw
NOTE: All parts must be cleaned before any repair service may be performed on them.
TROUBLESHOOTING
LENGTH INACCURACIES
POSSIBLE CAUSES:
1. Coupling loose between screw and stepper motor.
2. Bad stepper motor drive
3. Faulty unit (not repairable in the eld) Contact Hyd-Mech service department.
4. Improper Programmed Information:
•Length compensation
•Existing parameter(s) incorrect
•Incorrect blade kerf
GENERAL RULES – Normally, three types of length inaccuracies may occur
1. Inconsistent – lengths cut are not consistent, error changes. It doesn’t matter how long the part required is the
error is never the same.
Cause – most likely a drag or slippage between the vises and the material.
2. Consistent – lengths cut are consistent and the error is also consistent. The error always stays the same regard-
less of part length.
Cause – kerf value or backlash in the ball screw assembly
3. Linear – lengths cut are consistent but the error increases as the part length increases. The longer the part the
greater the error.
Cause –incorrect LENGTH and OFFSET values entered in the setup section of the parameters.
DIAGNOSIS:
Check and record existing parameter. Also check for proper blade kerf. By making a cut partway into a piece of material
and measuring the width of the cut, the operator can verify blade kerf.
