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.

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, see 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 180 ml (6 ounce) of Omega 690 gearbox oil. Clean the
magnetic plug, fit it and tighten again.
