12. Maintenance
Before any service and maintenance is done, the power must be disconnected,
it means the battery removed from the tool.
•
Remove the battery before you clean and store the machine.
•
For obtaining the best cutting results the chain and guide bar must be cleaned and
oiled regularly. Remove dirt with a brush and oil lightly.
•
Use biodegradable oil.
•
Clean the housing and other parts with a mild cleanser and a moist cloth. Never use
aggressive cleansers or solvents.
•
Prevent water from getting into the machine.
•
Use the blade protection when the machine is stored.
Lubrication hole
. Remove the guide bar and check that the lubrication hole (1) is not
blocked with sawdust or dirt. Lubricate with oil/grease.’
Guide bar
. Clean the nose wheel and chain groove of any dirt. If required, turn the
guide bar over to evenly share wear. A worn guide bar can be hazardous to use and
should therefore be replaced.
Chain
. The chain should be filed regularly to ensure the best result.
1. Ensure that the guide bar is securely attached.
2. Use a 4.0 mm (3/8”) round file (not supplied).
3. File all of the teeth with 3-4 strokes, so that they are uniform, as shown in the
illustration.
4. The height of the teeth must be checked regularly, and if they are too high, they must
be filed down using a flat file (not supplied).
Replacing saw chain / guide bar
Replace chain when cutters are too worn to sharpen or
when chain breaks. Only use replacement chain type
91PJ052X (art. no. 441634).
Inspect guide bar before sharpening or replacing chain.
A worn or damaged guide bar is unsafe and should be
replaced. A worn or damaged guide bar will damage the
chain. It will also make cutting harder.
