Regular Checks - Scheppach P-MGB4-1 Anleitung

3. Use a moist piece of cloth to clean the plastic parts. Do not use any cleaning agents, solvents, or
sharp objects.
4. During the course of work, wet grass and weed wraps around the drive shaft below the cutting
guard for technical reasons. Remove this, otherwise the engine will overheat because of too
much friction. Fig. 38

Regular checks

Keep in mind that following specifications relate to normal usage. Owing to circumstances (longer
periods of daily work, severe dust exposure, etc.), the specified intervals will become correspond-
ingly shorter.
• Before starting work, after tank filling, after impact or dropping:
Check the cutting tools for secure seating, general visual check for cracks and damage.
• Immediately replace damaged or blunt cutting tools, even in the event of minor hairline cracks.
• Sharpen cutting tools (also when required).
• Weekly inspection:
Lubrication of gear (also, if necessary).
• If necessary:
Retighten accessible fastening screws and nuts. You will avoid excessive wear and tear and dam-
ages of the tool, when you follow the instructions in this manual.
Replacing the line spool/cutting line Fig. 24-29
1. Pull off the line guard cap from the line spool (5) by forcefully pressing between the retaining plates.
2. Remove the spool with line remaining and the compression spring.
3. Remove the used up spool.
4. Take the new line spool and pull out 10 cm at both lines each.
5. Now, place the line spool (5) on the tapered spring, and guide both lines each through the round
metal lugs at the line spool housing.
6. Then place the spool cover on the new line spool (5). Turn it so that the plates of the spool cover
are pushed with the springs in the line spool housing.
7. Now, press the spool cover together with the line spool, until it engages in the line spool housing.
8. The knife (A) in the protective hood (18) shortens the trimming line to the correct length, when the
engine starts again.
Grinding the safety hood blade Fig. 18 (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 cutting blade or, if required, replace the cutting blade with a new one.
Grinding cutter blade (17)
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 scharpening.
