MAINTENANCE AND INSPECTION
I. nspecting the tool
Since use of a dull tool will cause the motor to malfunction, it should be replaced with a new one
without delay when abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure to do so could result in serious hazard.
3. Maintenance of the motor.
The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes
The motor employs carbon brushes which are consumable parts. When they become worn or near
”wear limit”, it could result in motor trouble. When an auto-stop carbon brush is equipped, the motor
will stop automatically. At that time, replace both carbon brushes with new ones. In addition always
keep carbon brushes clean and ensure that they slide freely within the brush holders.
5. Cleaning the device
To keep the device clean, clean it using a soft cloth damped in water with soap. Never use brushes or
other cleaning tools that may scratch/damage the device. Remember to prevent water from penet
rating inside the device through vents in the housing of the device. Clean the vents with a paintbrush
and compressed air.
TRANSPORTATION AND STORAGE
Shaking, crashing and turning upside down of the machine should be prevented when it is transported.
Store it in a properly ventilated surrounding with dry air and without any corrosive gas.
REGULAR CONTROL OF THE DEVICE
Regularly check the machine for signs of damage. If it should be damaged, please stop using it
immediately and contact your customer service to solve the problem.
What to do in case of a problem?
Please contact your customer service and prepare following information:
• Invoice number and serial number (the latter is to be found on the technical plate on the machine).
• If relevant, a picture of the damaged, broken or defective part.
• It will be easier for your customer service clerk to determine the source of the problem if you give
a detailed and precise description of the matter. The more detailed your information, the better
customer service will be able to solve your problem rapidly and efficiently!
CAUTION: Never open the machine without the authorization of your customer
service. This can lead to a loss of warranty!
