Maintenance
For the Pentruder 8-20 HF IQ / Pentpak 427 to remain in a condition which is safe for operation at
all times, certain maintenance is needed. Please read the instructions below carefully before any
service work is commenced.
For safe and uninterrupted operation of the machine, we strongly recommend that the complete
machine is brought back to your dealer for service at least once per year. At this service the
machine is checked for proper function and all components critical for safe and reliable operation
are checked and replaced if necessary.
Please respect the following maintenance instructions:
Warning!
No service or maintenance may be performed on the power pack unless it is
disconnected electrically from the mains.
Warning!
No service or maintenance may be performed on the saw head unless it is
disconnected electrically from the power pack.
Bolts for flush
cutting blades:
Always replace worn or damaged bolts with new of correct length and
quality. M8 x 25 10.9 or M10 x 25 10.9.
Cleaning:
The machine should be carefully cleaned and all functions checked and
found normal before use of the machine. If a high pressure cleaner is
used, the nozzle may
NOT
be pointed at rotating parts on the machine.
Avoid pointing at seals and electrical connectors.
Cords and connectors:
Check that all cords and connectors are in faultless condition.
Track guide rollers:
Check that the track guide rollers on the saw head can move freely
without too much friction. A certain amount of friction is always present as
the bearings are double sealed with both rubber and steel scraper seals.
Oil change in the saw
head 4-speed gearbox
(arm transmission):
Check the condition of the oil every week. If it is grey it needs to
replaced. This is an indication that the water seal needs to be
replaced, the below “Water seal”.
Change oil every 200 hours of operation.
Before attempting to change
oil,
and this is very important,
clean thoroughly around the plug and
blow with compressed air before the plug is removed. If dirt is allowed to
enter the gearbox, the gearbox may seize and any warranty is void. To
change oil, unscrew the oil-plug and drain the arm completely. Refill with
0.5 L (0.55 quart) of Omega 690 gearbox oil. Clean the magnetic plug, fit
it and tighten again.
Oil change in the travel
and arm feed worm gear
transmission:
This oil should be changed every 200 hours of operation when service is
done to the machine. The travel worm gear transmission is filled with 60
ml and the arm feed worm gear transmission with 80-100 ml of Omega
680 oil.
