with an oil syringe.
Cylinder fins (Fig.20)
•
Clean the cylinder fins (M) after each use. To do this, use
compressed air at low pressure or use a brush.
ATTEN-
TION! Wear safety glasses!
•
Dust and dirt between the fins on the cylinder may cause
the machine to overheat.
Other maintenance points before each use
• Check for leakage from oil or fuel tanks.
•
Check the unit for loose parts and screws. Specifically, the
chain, the bar and the hand grips.
•
If you find defects on the machine, fix them immediately.
Oil-/Fuel filter (Fig.21)
m
CAUTION!:
Never operate the saw without the Oil-/fuel fil
-
ter (L1/L2). After every 100 hours of operation the Oil-/fuel fil
-
ter needs to be cleaned or replaced when damaged. Drain the
Oil-/fuel tank completely before replacing the Oil-/filter.
• Remove the Oil-/fuel tank cap (12/14).
• Make a handle from soft wire.
• Insert it into the opening of the Oil-/fuel tank and hook the
Oil-/fuel hose. Pull the Oil-/fuel hose carefully to the open-
ing until you can grab it with your fingers.
m
NOTE
Pull the hose so it is not quite out of the tank.
•
Lift the Oil-/fuel filter (L1/L2) from the tank.
•
Remove the Oil-/fuel filter with a twisting motion and clean
it. If it is damaged, discard the Oil-/fuel filter.
•
Insert the cleaned Oil-/fuel filter or a new one. Plug one end
of the Oil-/fuel filter into the tank opening.
•
Make sure the Oil-/fuel filter is seated in the lower tank cap.
Move the Oil-/fuel filter with a long screwdriver to put it in
its proper slot.
•
Fill the Oil-/fuel tank with fresh saw chain oil or fuel mixture.
Put the Oil-/fuel tank cap on the tank.
Spark plug (Fig.17-19,22)
m
NOTE!:
In order for the saw motor to remain powerful,
the spark plug (G) must be clean and properly gapped (0.6-
0.7 mm). Spark plugs should be cleaned or replaced every 20
hours.
• Set the power switch (11) to „Stop“.
•
Remove the air filter cover (5) by removing the air filter
mounting nut (6). The cover can then be removed.
• Disconnect the spark plug from the ignition wire by gently
pulling it and turning the spark plug (G).
• Remove the spark plug with a spark plug wrench (20). Do
not use other tools.
• Clean the spark plug with a copper wire brush or replace it
with a new one. (Fig.22)
Adjusting the idling speed (Fig. 25)
If the saw chain continues to idle, you must correct the idle speed.
1. Remove the plug (T).
2. Let the engine warm up for 3-5 minutes (no high
speeds!).
3.
Turn the adjusting screw (R) using a flat-head screw
-
driver:
clockwise
- Idle speed increases (+)
counterclockwise
- Idle speed decreases (-)
Idling speed max.: 3500 min
-1
Contact the manufacturer if the saw chain continues to idle.
Attention!
Do not work on the chain saw!
Important:
No adjustments can be made to the plug L / H.
Carburetor setting
The carburetor has been set to its perfect adjustment at the
factory. If it requires adjusting, take the saw to your nearest au
-
thorized after-sales service outlet.
m
WARNING!:
You may not make settings on the carbure-
tor itself!
Bar
• Check after every 8 hours of work to ensure uniform wear.
Saw chain
Saw chain Tension
Periodically check the chain tension and adjust if necessary,
so that after use the chain is snug against the rail, but still
loose enough that it can be pulled by hand. (Fig.8)
Breaking in a new saw chain
A new chain and bar will need chain readjustment after as few
as 5 cuts. This is normal during the breakin period, and the in-
terval between future adjustments will begin to lengthen quick
-
ly.
Oil Supply Control
Always make sure the automatic oiler system is working properly.
Keep the oil tank filled with Chain, Bar and Sprocket Oil.
Adequate lubrication of the bar and chain during cutting
operations is essential to minimize friction with the guide bar.
Never starve the bar and chain of lubricating oil. Running
the saw dry or with too little oil will decrease cutting efficiency,
shorten saw chain life, cause rapid dulling of chain, and lead to
excessive wear of bar from overheating. Too little oil is evidenced
by smoke or bar discoloration.
To check the saw chain lubrication, hold the chain saw with the
saw chain over a piece of paper and give a few seconds of full
throttle.
The oil quantity can be checked on the paper. The chain must
always be thrown off a small amount of oil. After a few seconds, a
light oil trail must be visible.

Use screw (E) to reduce or increase the amount of oil.
Clockwise - oil quantity is reduced (-)
Counterclockwise - oil quantity increases (+)
