Maintenance; Sharpening The Saw Chain - Scheppach BCHS300-ProS Original Bedienungsanleitung

16. Maintenance

16.1 Re-tightening the saw chain
The saw chain (6) must not sag, although it should be
possible to pull it 1 - 2 millimetres away from the guide
rail in the centre of the guide rail.
1. Turn the hand wheel (13) anti-clockwise, sufficient-
ly that the guide rail (7) can be moved by hand.
2. Turn the chain tensioning wheel (11) anti-clock-
wise, so that the saw chain (6) is tensioned.
3. Turn the saw chain (6) by hand, to check it runs
freely. It must glide freely in the guide rail (7).
4. Tighten the hand wheel (13) for fastening the
guide rail (7) to the cover.
NOTE
The tension of a new saw chain must be checked after
a few minutes in operation, and adjusted if necessary.
To do so switch the device off, remove the battery and
apply the chain brake.
16.2 Clean guide rail oil guide groove
1. Remove the guide rail (7).
2. Clean the oil guide groove of dirt with a suitable
tool. Use the plastic spatula for this. Do not use
steel tools!
3. Attach the guide rail (7) again.
16.3

Sharpening the saw chain

Special tools are required to sharpen the saw chain;
these ensure that the chain cutting edges are sharp-
ened at the correct angle and to the correct depth.
We recommend having the saw chain sharpened by
a specialist.
16.4 Maintaining the guide rail (7)
1. Remove any burrs on the edge of the guide bar
using a metal file.
2. Clean the groove of the guide rail (7) using a brush
or compressed air. Replace the guide rail (7) as
soon as the guide nut is worn.
3. Turn the guide rail (7) after each use to ensure
even wear.
4. Check the sprocket at the tip of the guide rail (7)
for smooth running. If necessary, lubricate it with
a bearing oil. Let some bearing oil drip into the lu-
brication hole.
