P3: Machine Overheats
1. Check if fluid level in reservoir is low.
2. Check for low line voltage to transformer, causing low control voltage to directional
valve solenoid coils.
3. Determine if limit switches are set improperly when using footswitch, allowing cylinder
to bottom out at retraction and extension. This may cause hydraulic fluid to by-pass
over relief valve, creating heat buildup.
4. If jog mode is used during production, hydraulic fluid may pass over the NC valve and
create heat buildup.
5. Check for restrictions in the hydraulic system. Example: Contaminated cartridge valve,
restricted or kinked hose, etc.
P4: Reset On Motor Starter Kicks Out
1. Internal overheating. Refer to P3, above, for troubleshooting procedure.
2. Insure proper sized heater coils are being used. Reference the wiring diagram on page
3. Check for proper line voltage.
4. Check for loose connections on motor cable at starter or motor.
P5: Edges On Knife Blade Chipped By Material
1. Check knife clearance - .007" to .010". If not:
a. Combo table bolts may have become loose, allowing scale and contamination
between table and beam. Remove table and clean.
b. Combo table bolts may have stretched the threads in the beam. Remove table and
sand beam surface flat.
c. Knives may have been ground. Shim to recommended clearance.
2. Knives may be dull and are creating a pulling effect on the shearing edge.
3. Material may be too hard.
4. Material may be thicker than rated capacities.
