Maintenance - Scheppach BCH5300BP Originalbetriebsanleitung

Warning! Take extreme care during mowing work.
When doing such work keep a distance of 30 meters
between yourself and other people or animals.
Mowing
When mowing, you want to cut all the vegetation
down to the ground. To do this, set the line spool at
an angle of 30° to the right. Place the handle in the
required position. Remember the increased risk of in-
jury to the user, watchers and animals, and the dan-
ger of damaging property due to objects (for example
stones) being thrown.
Warning! Do not use the equipment to remove ob-
jects from footpaths, etc. The equipment is a power-
ful tool and can throw small stones and other objects
a distance of 15 meters or more, causing injuries and
damage to cars, houses and windows.
Jamming
If the cutting blade jams as a result of attempting to
cut vegetation that is too dense, switch off the engine
immediately. Remove the grass and scrub from the
equipment before you restart it. Fig. 49
Preventing recoil
When you work with the blade, there is a risk of recoil
if it strikes solid objects such as tree trunks, branch-
es, tree stumps, stones or the like. This will throw the
equipment backwards in the direction opposite to
the rotation of the tool. This can cause you to lose
control of the equipment. Do not use the blade near
fences, metal posts, boundary stones or foundations.

10. Maintenance

Before performing any maintenance or cleaning
work, always turn off the engine and pull out the
spark boot plug.
1. Do not spray the unit with water. It damages the
engine.
2. Clean the unit with a cloth, hand brush, etc.
Maintenance schedule

Spark plug check
Expert inspection is required:
• If the brush cutter strikes an object.
• If the motor stops suddenly
• If the blade is bent (do not align!)
• If the gears are damaged.
Replacing the line spool/cutting line Fig. 41 - 46
1. Dismantle the line spool (1) as described in sec-
tion 8.3 Assembly. Press the spool together and
remove one half of the housing. Fig. 42
2. Take the spool plate out of the line spool housing.

3. Remove any remaining cutting line.
4. Place the new cutting line in the center and hang
the loop which has formed into the recess in the
spool splitter. Fig. 44
5. Wind the line onto the spool counter-clockwise
and under tension. The spool splitter will sepa-
rate the two halves of the line. Fig. 45
6. Hook the last 15cm of the two ends of the line
onto the opposite lying line holders of the spool
plate. Fig. 46
7. Thread the two ends of the line through the metal
eyelets in the line spool housing .
8. Press the spool plate into the line spool housing.
Fig. 43
9. Pull the two line ends sharply to release them
from the line holders.
10. Join the housing parts together again. Fig. 42
11. Cut the excess line to a length of around 13cm.
This will reduce the load on the engine when
starting and warming up.
12. Remount the line spool (see section 8.3). If you
are replacing the complete line spool, skip points
3-6.
Grinding the safety hood blade Fig. 24 (A)
The safety hood blade can become blunt over time.
• When you notice this, undo the screw holding the
safety hood blade on the safety hood.
• Clamp the blade in a vise.
• Sharpen the blade with a flat file and make sure
that the angle of the cutting edge is not altered in
the process. File in one direction only.
• Important! Reassemble the cutting knife.
Replacing and resharpening the cutting blade at the
end of the mowing season always resharpen the cut-
ting blade or, if required, replace the cutting blade
with a new one.
Grinding cutter blade (4)
If the blade is only slightly dull, they can re-sharpen
themselves.
• Clamp the blade in a vise.
• Sharpen the blade with a flat file and make sure
that the angle of the cutting edge is not altered in
the process. (~25°) File in one direction only.
Replace the blade at the latest after five times sharp-
ening.
Replace the blade with heavy wear or broken blade.
Unbalanced blades will cause the brush cutter to vi-
brate violently-risk of accident!
Change and clean the spark plug Fig. 35 - 36
1. Once the engine has cooled, remove the spark
plug using the socket spanner supplied.
2. Clean the plug with a wire brush.
3. Using a feeler gauge; set the gap to 0.5-0.7 mm.
4. Install the spark plug carefully by hand, to avoid
cross-threading.
5. After the spark plug is seated, tighten with span-
ner to compress the washer.
