Care and Maintenance
7.1
General
•
Unplug the rotary tool before performing any maintenance on it.
•
Keep the tool housing and accessories clean and free of oil and grease using mild
soap and a damp (not wet) cloth. Do not let solvents like brake fluid, gasoline,
petroleum-based products, etc., contact plastic parts of the housing. Cleaning with
these substances can harm the plastic and compromise the integrity of the double
insulating system.
•
Inspect the mounting screws regularly. They should be properly tightened. If any
are found to be loose, tighten immediately or serious injury could result.
•
Use care to see that the motor winding does not become damaged or wet with oil or
water.
•
The carbon brushes should be checked every 2 to 6 months, depending on
frequency of use, and replaced if worn. Worn brushes could cause motor damage
and should be replaced with identical parts if worn to or near their limit. Brushes
should be kept clean and free moving within their holder.
•
Keep the vents and the insides of the tool clear of dust and debris. Ideally, this can
be done with an air blowgun. This will help prevent possible electrical shorts and
ensure proper cooling. Always use approved eye protection when using air blowguns
to clean tools.
•
Inspect the cord regularly and have it replaced by an authorized repair facility if it is
damaged.
•
Lubrication for this tool is done at the factory and should not be necessary again
under normal use.
•
An authorized repair centre should do any repairs, modification, or maintenance
that involve opening or disassembling the tool housing.
7.2
Accessories
•
Use only accessories that are recommended by the manufacturer for your model.
Accessories that may be suitable for one tool may become hazardous when used on
another tool.
•
Always attach grounded extension cords to grounded outlets.
•
If you must use an extension cord, be sure that the gauge is large enough to carry
the amount of current necessary for your power tool. If not, your tool may
experience a loss of power, excessive voltage drop or overheating. The smaller the
gauge number, the heavier the cord.
