Adjustable flow oil pump is a special
option.
Different quantities of oil are required for
different bar lengths, types of wood and
cutting techniques.
Use the adjusting screw (1) (on
underside of machine) to vary the oil
feed rate as required.
Ematic position (E), medium oil flow rate
–
N turn the adjusting screw to "E"
(Ematic position).
To increase oil feed –
N turn the adjusting screw clockwise.
Turn reduce oil feed –
N turn the adjusting screw
counterclockwise.
NOTICE
The chain must always be wetted with a
film of lubricant.
N Turn the guide bar over – every time
you sharpen the chain and every
time you replace the chain – this
helps avoid one-sided wear,
especially at the nose and
underside of the bar.
N Regularly clean the oil inlet hole (1),
the oilway (2) and the bar groove
(3).
N Measure the groove depth – with the
scale on the filing gauge (special
accessory) – in the area used most
for cutting.
If groove depth is less than specified:
N Replace the guide bar.
The drive link tangs will otherwise
scrape along the bottom of the groove –
the cutters and tie straps will not ride on
the bar rails.
