Maintenance
For the Pentruder 8-20HF / 8-20iQ / Pentpak HF-power pack 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.
Blade flange:
The threads on the centre screw and the female thread on the blade
flange should be clean and well lubricated. The friction surfaces on the
blade flange should be kept dry and clean.
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.
Cables:
Check that all cables 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 80 hours of operation.
Important! Before attempting to change oil, 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.
