Example (A) corresponds to a chain that is too tight.
Example (B) corresponds to a chain that is too
loose.
6. Tighten the bolts (1) with a strength of (12-15 Nm)
then check that the chain slides smoothly round
the bar, maintaining the appropriate tightness when
it is moved by hand. If necessary, adjust the tension
again.
New chains have the tendency to dilate
when they are used for the fi rst time. Check
and adjust the tension with frequency.
A loose chain can easily come away and this
will cause both the chain and the chain bar
to wear out quickly.
6.3. POINTS TO CHECK BEFORE OPERATING
Check the whole machine for any loose parts (nuts,
bolts, screws, etc.) or damage. Repair or replace the
parts that are necessary before using the machine.
Check that there are no fuel leaks.
Do not use the machine if it is damaged or incorrectly
adjusted.
Before commencing a task, it is necessary to plan the
path where the tree will fall, to have a clear escape
route and to ensure feet are safely supported.
Inspect the working area and remove all obstacles. Do
not commence work until the working area is clear.
Check the working area and the direction in which the
branches and/or trees will fall.
Check that the air fi lter is not dirty. If necessary, clean
it thoroughly before operating.
6.3.1. CHECKING THE SAFETY BRAKE
When kickback occurs, the tip of the chain bar rises
brusquely, the chainsaw changes its angle and, as this
movement is so quick, the user does not have time
to change the position of his left arm, which bangs
against the protective guard and activates the safety
brake.
The safety brake can be activated whenever desired,
by moving the safety guard forwards.
To release the safety brake, pull the safety protector
backwards until a "click" can be heard.
Remember to check the brake every day the chainsaw
is used:
1. Switch off the engine.
2. Activate the safety brake by moving the lever
forward until a "click" can be heard.
3. Hold the chainsaw horizontally with the tip about
40 cms over a piece of wood, take your hand off
the front handle allowing the chainsaw to rotate on
your right hand and hit the wood.
