Safety and operating instructions
◆
Check that the tool retainer is not worn and that
it functions as it should. Never use the
equipment if you suspect that it is damaged.
◆
Check for wear in the tool chuck.
◆
Check the working tool, make sure that it is
sharp and not worn out. Check that the tool
shank is clean.
◆
Replace worn components in good time.
In order to ensure that the machine remains within
the stated vibration level values, the following
checks must be performed:
Wear check
If a working tool with a worn shank is used,
machine vibration will increase. Avoid such
vibration by checking for shank wear before
mounting the working tool on the machine.
◆
Use the shank gauge that corresponds to the
dimension of the working tools shank. If the
gauge can be inserted beyond point A in the
tool chuck (point B) then the tool chuck must be
replaced immediately.

Air filter check
A clogged air filter will eventually cause damage to
the engine. Check the air filter regularly.
1. Unscrew the air filter cover.
2. If the air filter is dirty, it must be replaced.
Never wash the air filter.
3. Clean filter container.
Spark plug check
If the spark plug electrodes are very dirty or
burned, replace the spark plug. The spark plug is
placed under the service cover, mounted in the
cylinder head. See the section "Main parts" for
position of the spark plug.
Only use Champion RCJ8 and make sure that the
electrode gap is 0.6-0.7 mm (0.024-0.028 in.)
before fitting the spark plug. Tighten the spark plug
using the correct tightening torque, see Spare
parts list.
