Replacing saw chain
The first signs of a worn chain are abnormally long saw times and
blue smoke emerging from the cut. When replacing the saw chain
we recommend the following method.
Warning!
Before performing any maintenance or service work,
lower the attachment to the ground and shut off the
engine. Turn off any master shut-offs and do not allow
personnel in the cab.
Important!
When working on the saw chain always ensure the
engine is shut off and wear safety gloves to prevent
injuries. Remove the saw chain when making any
adjustments or servicing the saw unit.
1.
Place the unit steady on the ground with the saw unit
facing up (when possible).
2.
Depressurize the chain tension system by pushing in the
pilot valve (1).
3.
Use the retraction tool (4) to retract the bar holder (2)
until the locking device (3) automatically engages.
4.
Remove the saw chain.
5.
Make sure that the drive sprocket isn’t worn or damaged.
Replace if necessary.
See Replacing drive sprocket
6.
Install the new saw chain and retract the tool (4) until the
locking device (3) can be pulled out.
7.
Operate the saw carefully a few times to secure the
pressure in the chain tensioner. If after replacing a chain
it repeatedly jumps off the saw bar, you may have to
bleed the system.
