5.3.1 Maintaining the cutting saw
The JAPA 315 firewood machine is equipped with a chainsaw which corresponds to the 13” chain and
bar of a traditional chainsaw. The pitch is 0.325 with 56 loops. Check the blade on a daily basis and
sharpen or replace it as necessary. We recommend turning the bar every time you replace the chain
so that the guide groove, if worn, does not damage the new chain.
A. Loosen the saw bar fastening screws (2 pcs)
with a 13 mm spanner.
B. Tighten the chain-tensioning screw with a 5
mm hex key until the side loops and cutting teeth
barely touch the bottom of the groove.
ALWAYS DEACTIVATE THE MACHINE AND DISCONNECT THE POWER SOURCE WHEN CARRYING
OUT MAINTENANCE!
AFTER MAINTENANCE, ALWAYS REATTACH ALL THE GUARDS YOU HAVE REMOVED AND CHECK
THE OPERATION OF THE SAFETY DEVICES BEFORE BEGINNING OPERATION!

Chain replacement
•
When installing a new chain, soak the chain in oil overnight to ensure that the oil penetrates all sections of the chain.
•
Do not use a worn drive wheel or saw bar with a new chain. We recommend that you replace the saw bar after every
second chain, and the drive sprocket after every third chain.
•
Once you have installed the new chain, perform quick pumping motions with the sawing handle before beginning
operation, so that sufficient oil is applied to the chain.
•
When starting off, check the chain tension frequently. The new chain tends to initially conform to the saw bar.
•
Saw lightly at first and avoid excessive pressure.
USE PURE MINERAL OILS INTENDED FOR BLADE LUBRICATION ONLY.
DO NOT USE BIO OR WASTE OIL!
