Different quantities of oil are required for
different bar lengths, types of wood and
cutting techniques.
N Use the adjusting screw (1) (on
underside of machine) to vary the oil
feed rate as required.
N Ematic position (E), medium oil feed
rate – turn the adjusting screw to "E"
(Ematic position).
N Turn the adjusting screw clockwise
to increase oil feed rate.
N Turn the adjusting screw
counterclockwise to reduce oil feed
rate.
When using as rescue saw:
N Turn the adjusting screw (on
underside of machine) clockwise as
far as stop to obtain maximum oil
feed rate.
NOTICE
Your 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.
