Product Inspection Range
When performing the inspection, make sure the engine is stopped and empty. The durability of parts
differs depending on the frequency of use.
When the impact or rotation sound is abnormal (the impact rhythm is different, the work efficiency is
reduced, the vibration is large, etc.) request inspection and repair.
Anvil (Drive at the Tip)
Wear out: Reduce performance and efficiency. Recommend early replacement.
Cracks. There is a risk of breakage. Stop using and request a repair.
Bolts
Make sure all the bolts are tightened.
Impact Mechanism
When the contact places of
the anvil and ham
mer become worn-out and dull by percussion, the tool
will have reduced power. This will cause a longer percussion than normal condition, causing
early damage and broken parts.
1 . Empty all oil in the gear box and completely remove the hammer housing.
2. C heck the degree of ware on the anvil and hammer at least once every month.
3. Apply grease around the contact areas.
Fuel Pipe
Check that the fuel pipe is not twisted or broken. If broken, replace immediately.
Leakage of Fuel or Oil
Engine: If fuel leakage is confirmed, it may cause an accident or malfunction. Stop using immediately,
check the engine, and request repair if necessary.
Main unit: If an oil leak is confirmed, it may cause an accident or breakdown. Stop using
immediately, check the unit, and request repair if necessary
.
Socket
Wear out of square part: It may cause performance degradation and fall off from the anvil.
Worn pinholes: Cannot be fixed and may fall of the anvil.
Cracks: There is a risk of breakage and scattering. Stop using and replace with a new one.
Throttle Lever
When pulling the throttle lever, check that there is no abnormality in pulling or returning.
Storage
Damaged parts should be repaired before storage.
1. Clean each part and coat other areas that may rust with a light film of oil.
2.
If storing over three weeks:
•
Drain the fuel from the fuel tank.
•
Run the engine without load until the engine stops and exhaust all the remaining fuel in the
carburetor.
