Lubrication Of The Cutting Equipment; To Do A Check Of The Saw Chain Lubrication - Zenoah GZ4350 Manual De Usuario

The more you use a saw chain the longer it becomes. It
is therefore important to adjust the saw chain regularly
to take up the slack.
Do a check of the saw chain tension every time you
refuel. Tension the chain as tightly as possible, but not
so tight that you cannot pull it round freely by hand.
Note: A new saw chain has a running-in period during
which you should do a check of the tension more
frequently.
1. Undo the bar nuts that hold the clutch cover/chain
brake. Use the combination spanner.
2. Tighten the bar nuts by hand as tight as you can.
3. Raise the tip of the bar and stretch the saw chain by
tightening the chain tensioning screw. Use the
combination spanner. Tighten the saw chain until it
does not sag from the underside of the bar.
4. Tighten the bar nuts using the combination spanner
and lift the tip of the bar at the same time.
5. Make sure that you can pull the saw chain round
freely by hand and that it does not sag from the
underside of the bar.
The position of the chain tensioning screw on our
chainsaws varies from model to model. See instructions

Lubrication of the cutting equipment

To do a check of the saw chain lubrication

Do a check of the chain saw lubrication each time you
refuel.
1. Start the product and let it run at 3/4 throttle. Aim the
tip of the bar at a light coloured surface about 20 cm
(8 inches) away.
2. After 1 minute running you should see a distinct line
of oil on the light surface.
What to do if the saw chain lubrication is not working
Do the following if the saw chain lubrication is not
working:
• Do a check of the oil channel in the bar to make sure
that it is not obstructed. Clean if necessary.
• Do a check of the groove in the edge of the bar to
make sure that it is clean. Clean if necessary.
• Make sure that the bar tip sprocket turns freely and
that the lubricating hole in the tip sprocket is not
blocked. Clean and lubricate if necessary.
