10. Troubleshooting

A
Danger!
Before carrying out any fault service
or maintenance work, always:
1. Switch machine off.
2. Wait until the saw has come to a
complete stop.
3. Disconnect the mains plug.
A
Cutting hazard when touching
the rotating cutterblock!
Unintentional startup of the machine
may lead to serious injuries.
A
Risk of burning!
Shortly after working the planer
knives may be hot - Let the device
cool down before rectifiying any mal-
function.
A
Danger!
After each malfunction rectification:
Put back into operation and check all
safety installations.
Motor does not run:
• Undervoltage relay tripped by tem-
porary voltage failure.
 Start again.
• No mains voltage.
 Check cables, plug, outlet and
mains fuse.
• Motor has overheated, e.g. due to
blunt planer knives, overloading or
chip buildup.
 Remove cause for overheating
and allow to cool down for
approx. 10 minutes, then start
again.
• Contact pins of outfeed table or dust
chute have not engaged in the limit
switch.
 Correctly install outfeed table or
dust chute, respectively. If neces-
sary, adjust contact pins.
 When thickness planing: Check if
the setting screw of the chip
guard is turned to the end position
and correct if necessary. Only
then the contact switch is acti-
vated and the machine can be
switched on (see chapter 6.3
"Operation as thickness planer").
 When surface planing: Check if
the chip extraction guard is
mounted correctly. Only then the
contact switch is activated and
the machine can be switched on
(see chapter 6.1 "Operation as
surface planer").
Performance lessens
• Planer knives blunt
 Install sharp knives.
• Drive belt slips
 Re-tension drive belt
Planed surface not smooth
• Planer knives blunt
 Install sharp knives.
• Planer knives blocked by chips
 remove chips.
• Moisture contents of work piece too
high
 Dry work piece.
Planed surface cracked
• Planer knives blunt
 Install sharp knives.
• Planer knives blocked by chips
 remove chips.
• Work piece was planed against the
grain
 Plane work piece in opposite
direction
• Too much material removed in one
pass
 Make several passes at less
depth of cut.
Feed rate too little (thicknessing)
• Resin buildup on thicknesser bed
 Clean thicknesser bed and apply
light coat of anti-seize compound.
• Feed rollers stiff
 Repair feed rollers.
• Drive belt slips
 Re-tension drive belt
Work piece jammed
(thicknessing)
• Too much material removed in one
pass
