below to reduce the tension.
4. Undo the lock nuts for the bar.
5. Reduce the tension of the chain by slowly
turning the adjuster screw anticlockwise.
6. Pull the chain backwards and forwards on
the bar. The chain is correctly tensioned
when it rests against the underside of the
bar, but can still be pulled along the bar by
hand. Increase the tension of the chain by
turning the adjuster screw clockwise.
7. When the chain is correctly tensioned, hold
up the tip of the bar and firmly tighten the
two lock nuts.

Checking and filling the chain oil
1. Check at regular intervals that the
automatic lubrication system is working
properly.
2. Always check the oil level before use.
FIG. 13
3. Fill the oil reservoir to about half of the
level glass. Proper lubrication is essential to
minimise the friction to the bar.
4. Start the pruning saw and run the chain
about 20 cm over a suitable surface for
15 seconds. If the chain lubrication
is working properly there should be
splashing of oil on the surface. If there is
no splashing, clean the oil outlet behind
the bar and check that the flow of oil is
not blocked. Check the oval seal is in place
between the oil outlet and the bar.
NOTE:
• Never use the saw if the lubrication is not
working properly. Inadequate lubrication
results in the chain quickly going blunt
and reduces its lifespan. It also overheats
the bar and and will cause it to wear out.
Smoke or discolouration of the bar are
signs of inadequate lubrication.
Lubricating the sprocket
IMPORTANT:
• Wear heavy-duty safety gloves when
handling the bar and chain.
• Switch off the pruning saw, pull out the
plug and wait until all moving parts have
completely stopped before lubricating it.
The bar sprocket should be lubricated at intervals
of 25 working hours, or once a week during
intensive Use.
1. Clean the sprocket.
2. Press grease from the nozzle of the grease
gun into the lubrication hole (see arrow)
until it comes out by the edge of the bar.
A grease gun with a slim nozzle simplifies
effective lubrication.
FIG. 14
3. Pull round the chain by hand. Repeat until
all the sprocket has been lubricated.
NOTE:
• It is not necessary to remove the chain to
lubricate the sprocket.
• Clean the sprocket before lubricating it.
• Failure to follow the instructions for
lubricating the sprocket can cause it to
seize, and will invalidate the warranty.
Sharpening the chain
WARNING!
• A worn or incorrectly filed chain can result
in kickback, which can result in fatal and/
or serious personal injury.
• Wear heavy-duty safety gloves when
handling the bar and chain.
• The filing should be done with a special
tool to ensure that the chain has the right
angles and height.
