9.2.6 Maintenance of the guide rail
• Rotate the rail every time around, if you have
sharpened or replaced the chain. This avoids a one-
sided wear of the rail, particularly at the top and bottom.
Clean regularly.
1 = the opening for the oil supply 2 = the oil passage
3 = the groove of the rail regularly
9.2.7 Maintenance and sharpening of the saw chain
The right sharpened chain
A properly sharpened chain goes effortlessly through the
wood and requires very little pressure. Do not work with
a dull or damaged saw chain. It increases physical effort,
increases the the vibration and leads to unsatisfactory
results and higher wear.
• Clean the chain.
• Check for breaks in the parts and for damaged rivets.
• Replace damaged or worn chain parts with matching
spare parts, which you may file in the form and size of
the original parts, if necessary.
• The sharpening of a chain should be carried out only
by experienced users!
Note the specified angles and measurements below. If
the saw chain is not correctly sharpened or the depth
dimension is too small, there is a higher risk of backlash
effects and injuries resulting out of this!
The saw chain cannot be fixed on the guide rail. It is
therefore best to take the chain from the rail and then to
sharpen it.
• Select a suitable sharpening tool for the chain pitch.
See "Technical Specifications" for the approved chain
pitches.
The chain pitch (for example, 3/8 ") is highlighted in the
depth gauge of each blade.
Use only special files for saw chains! Other files have
the wrong form and the wrong sharpening.
Select the diameter of the file according to your chain
pitch. Please also pay attention to the following angle
when sharpening the chain blade.
A = filing angle
B = angle of the side plate
The angle must also be maintained for all blades.
In uneven angles, the chain will run irregularly, wear out
quickly and break prematurely.
