Cleaning The Guide Bar; Replacing The Saw Chain; Replacing The Fuel Filter - Makita EA7900P Operator's And Safety Manual

Cleaning the guide bar

CAUTION: Protective gloves must be worn.
Regularly inspect the bearing surfaces of the guide bar for
damage, and clean them with a suitable tool.

Replacing the saw chain

CAUTION: Use only chains and guide bars designed for
this saw (see the Extract from the spare-parts list)!
Check the sprocket before mounting a new chain.
Worn out sprockets (12) may damage the new chain and must
therefore be replaced.
Remove the sprocket guard (1) (See „PUTTING INTO OPE-
RATION" figs. B).
Remove the chain and guide bar.
Remove circlip (13).
CAREFUL: The circlip will jump out of the groove unless you
hold it down with your thumb while removing it.
Remove cup-disc (15).
Replace the old sprocket (12) with a new one (16). For the part
number consult the "Extract from the spare parts list".
Assemble the new sprocket, cup-disc and circlip.
For replacing the guide bar, chain, and sprocket see „PUTTING
INTO OPERATION A-H".
NOTE:
New chains stretch, so check the chain tension frequently (see
"Checking the chain tension").

Replacing the fuel filter

The felt filter (17) of the fuel filter can become clogged.
It is recommended to replace the fuel filter once every
three months in order to ensure unimpeded fuel flow to the
carburetor.
To remove the fuel filter for replacement, pull it out through
the tank filler neck using a piece of wire bent at one end to
form a hook.
