affect the power tool's operation on a daily basis. If
damaged, have the power tool repaired before use.
Many accidents are caused by poorly maintained
power tools.
Sawing chain
Working with a blunt sawing chain causes
premature wear of the sawing chain, the chain
wheel and the guide rail. It can also cause the
sawing chain to break. It is therefore important that
the sawing chain is sharpened in good time.
Sharpening should be carried out by a specialist
workshop.
The sawing chain cutters have the following angles:
cutting angle = 55°, sharpening angle = 30°. A 4.0-
mm round file is required to sharpen the sawing
chain. Use a flay file to file the depth gauge to a
height of 0.65 mm.
4,0 mm
55°
Replace the sawing chain if:
- The length of the cutting edges is less than 5 mm.
- There is too much space between the driving links
and the rivets.
- The cutting speed is too slow.
- The cutting speed cannot be increased even after
sharpening the sawing chain multiple times.
For replacement sawing chains, refer to the
Accessories chapter.
Guide rail
Occasionally, some ball bearing grease must be
applied (with a grease gun, not provided) through
the lubrication holes (5) for the deflector star at the
front end of the guide rail.
The lower edge of the guide rail is particularly
susceptible to wear. To avoid one-sided wear of the
guide rail, it should be turned every time the sawing
chain is sharpened. If necessary: Debur the edges
and file the edges flat with a flat file.
You should also take this opportunity to clean the
groove and the oil inlet bores (14) of the guide rail.
Replace the guide rail if
- The groove does not match the height of the
driving links (which must never touch the
underside).
- If the inside of the guide rail is worn and the sawing
chain tends towards one side as a result.
If the guide rail is replaced, the sawing chain must
also be replaced. For replacement guide rails, refer
to the Accessories chapter.
Chain wheel
If the chain wheel (19) shows signs of greater wear
(deep indentations), it must be replaced.
See the chapter on Repairs.
Lubrication
Every 40 operating hours, top-up grease through
the grease nipple on the gearbox housing using a
30°
0,65 mm
grease gun:
12 g high-temperature composite lithium grease
12. Troubleshooting Guide
When attaching to the cordless multidrive, the
rod ends cannot be pushed into each other.
- Read the operating instructions supplied with the
cordless multifunction drive.
Machine switches off during sawing.
- Is the saw chain (8) tensioned too much? See
chapter 6.1.
- Too much pressure applied when sawing? See
chapter 7.2.
- Is the guide rail defective? (bent, damaged...)?
- Sawing chain (8) blunt? See chapter 11.
- Wood shavings under the sprocket cover (11)
cause a blockage? Clean.
No chain lubricating oil is supplied.
- Is the oil container empty? See chapter 6.2.
- Oil channel (15) or oil inlet bore (14)
contaminated? See chapter 7.
