Maintenance; Replacing Carbon Brushes - Princess auto pro point User Manual

3. Double insulated tools are equipped with a polarized plug (one blade is wider than the other). This plug will
fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does
not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double
insulation eliminates the need for a three wire grounded power cord and grounded power supply system.
4. Grounded tools must be plugged into an outlet properly installed and grounded in accordance with all codes
and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use any adapter
plugs. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If
the tool should electronically malfunction or break down, grounding provides a low resistance path to carry
electricity away from the user.
5. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away
from heat, oil, sharp edges or moving parts. Do not operate this tool if the power cord is frayed or damaged.
Replace damaged cords immediately. Damaged cords increase the risk of electric shock. Do not modify the
plug in any way.
6. When operating a power tool outside, use an outdoor extension cord marked "W-A" or "W". These cords
are rated for outdoor use and reduce the risk of electric shock. Use in conjunction with a Ground Fault Circuit
Interrupter (GFCI). If operating a power tool in a damp location is unavoidable, the use of a GFCI reduces the
risk of electric shock. It is recommended that the GFCI should have a rated residual current of 30 mA or less.
7. Avoid using an unnecessarily long extension cord. Choose a cord that is appropriate for the situation, as a
cord that is too long and running across the floor can be more dangerous than helpful. Using a cord that is too
long or too thin could damage the tool. Unroll the cord completely to prevent it from overheating.
8. Place the electrical cord in a position that prevents it from coming into contact with the tool and from getting
caught into the work piece. The cord should always stay behind the tool.

MAINTENANCE

• The brushes should be checked periodically and worn-out brushes should be replaced. After replacing, inspect
whether the new brushes can move freely in the brush holder. Run the motor for 15 minutes without load to
shape the brushes, so that they are properly aligned with the commutator.
• Keep the vent passage clear from dirt. Clean off the accumulated dust and oil dirt periodically.
• During normal operation, if anything happens, the power supply should be cut off at once and the tool should
be checked and repaired.
• Clean the tool after each use.
CAUTION! Only qualified service personnel should repair the tool.

REPLACING CARBON BRUSHES

• Using the parts list included, locate the carbon brushes. Remove the brush holder caps with a screwdriver and
inspect the carbon brushes. Replace them when they are worn up to about one third.
• Take the old brush out and install new brushes. Remove all of the brushes at once. Make sure the brush slides
freely within the brush housing.
• Run the motor for 15 minutes without load to shape the brushes, so that they are properly aligned with
the commutator.
UNPACKING
1. Carefully remove the parts and accessories from the box.
2. Make sure that all items listed in the parts lists are included.
3. Inspect the parts carefully to make sure the tool was not damaged while shipping.
4. Do not discard the packaging material until you have carefully inspected and satisfactorily operated the tool.
WARNING! If any part is missing, do not operate the tool until the missing parts are replaced. Failure to do so
could result in serious personal injury.
